März 2026 * * ![](https://www.servicenow.com/docs/portal-asset/ico-clock) 33 Minuten Lesedauer Parameters control the behavior of a particular MID Server and have lower precedence than MID Server properties. |-| | | [ ] {#mid-server-parameters__table_ibb_fsf_khb} To add a parameter to a MID Server, see [Add a MID Server parameter](https://servicenow-prod.fluidtopics.net/VYH5xHLIPq1GhC9qbQDc9Q#t_SetMIDServerParameters "Use a MID Server parameter to control the behavior of a particular MID Server."). Wichtig: Changes to parameters only take effect when the MID Server is started (or restarted). Hinweis: The value of any MID Server parameter in the config.xml file can be encrypted. See [Encrypt or decrypt MID Server configuration file values](https://servicenow-prod.fluidtopics.net/iCgc9bn4JQYK9vgd1wAC6w "The value of any MID Server parameter in the config.xml file can be encrypted. The attributes for all encrypted values are managed from within the configuration file, including the security attribute of the login password.") for more information. ## Required parameters {#mid-server-parameters__section_required} Hinweis: Using special characters in an XML configuration file requires you to encode them. url : Specifies the URL to the associated instance. Normally the URL is similar to https://instance.service-now.com, where you replace instance with the instance name. If you host your own instance, use the URL set by your organization. * Type: string * Default value: none {#mid-server-parameters__ul_dgz_nd1_s1b} mid_sys_id : Records the MID Server record's unique identifier. This parameter should be empty when you initially configure a MID Server. Do not change the value. * Type: string * Default value: automatically set (GUID) {#mid-server-parameters__ul_egz_nd1_s1b} name : Use this parameter to supply a name that is meaningful for you. If you do not supply this parameter, the MID Server uses the default value. A set of business rules synchronizes the name in the configuration file with the name in the MID Server record. The business rules ensure that changing the name in one location also changes the name in the other location. * Type: string * Default value: YOUR_MIDSERVER_NAME_GOES_HERE {#mid-server-parameters__ul_fgz_nd1_s1b} mid.instance.username or glide.glidesoap.username : If the ServiceNow instance has authentication enabled, as it is by default, set this parameter to define the user name the MID Server should use to log in to the instance. This user should have the mid_server role on the ServiceNow instance in order to access necessary tables and fields. You can use this parameter to define user names with special characters. * Type: string * Default value: none {#mid-server-parameters__ul_ggz_nd1_s1b} mid.instance.password or glide.glidesoap.password : If your ServiceNow instance has authentication enabled, as it is by default, set this parameter to define the password the MID Server should use to log in to the instance. You can use this parameter to define passwords with special characters. * Type: string * Default value: none {#mid-server-parameters__ul_hgz_nd1_s1b} ## CIM parameters {#mid-server-parameters__section_cim} mid.cim.batch.size : Specifies the maximum number of messages sent at once to a CIM server. * Type: integer * Default value: 1 {#mid-server-parameters__ul_gdw_5pp_b3b} mid.cim.request.interval : Specifies the number of milliseconds to wait between requests to the same Common Information Model Object Manager (CIMOM). * Type: integer * Default value: 0 {#mid-server-parameters__ul_fhg_vpp_b3b} mid.cim.host.connection.limit : Specifies the maximum number of simultaneous connections to each CIMOM. A value of zero disables simultaneous connections. * Type: integer * Default value: 0 {#mid-server-parameters__ul_n1x_vpp_b3b} ## Connection parameters {#mid-server-parameters__section_connection} glide.mid.fast.responses : Instructs the MID Server to try sending messages to the instance as soon as they are ready. Normally the MID Servers end messages to the ServiceNow instance serially (that is, one message at a time). Since many probes can be run in parallel, there can be multiple messages transmitted simultaneously to the instance. Setting this parameter to true may decrease the time between a probe's completion and its response arriving at the instance. However, the multiple simultaneous messages consume resources, decreasing the overall instance responsiveness. If there are communications problems, this parameter's value can also cause a logjam on the MID Server, as threads normally used for running probes may become consumed for sending messages. Generally, leave this parameter out of your configuration. Setting it to true is meaningful only under very special circumstances. * Type: true \| false * Default value: false {#mid-server-parameters__ul_nn3_ht5_b3b} glide.mid.max.sender.queue.size : Places an upper limit on how large the queue is allowed to get. The MID Server starts deleting queued messages if this limit is exceeded. When the MID Server generates messages to the ServiceNow instance faster than it can send them, it queues them temporarily on the file system of the MID Server's host. This queue is normally quite small, and is completely emptied as soon as the MID Server processing slows for a short period. However, this queue can grow in size when there are communication problems between the MID Server and the instance, and especially if there is an integration running on the MID Server. The parameter is of the form {number}{multiplier}, where {number} is any positive decimal number including non-integers, and the optional multiplier is any spelling of bytes, kilobytes, megabytes, gigabytes, or terabytes (only the first character is tested, and the test is case-insensitive). The default multiplier is bytes. White space is liberally tolerated. The following strings all represent valid parameters: "1000000000", "0.5m", "5 GB", "7.67gigas", "145.69392 meg", and "1.1 terra". * Type: string * Default value: 0.5 GB {#mid-server-parameters__ul_n2z_ht5_b3b} instance.date.format : Specifies the format the instance uses for dates and times. The primary impact of setting this parameter is to allow the MID Server to correctly refresh its start and stop times on the MID Server record in ServiceNow. The format of this date/time string is identical to that used by the Java SimpleDateFormat class. * Type: string (Date format) * Default value: yyyy-MM-dd HH:mm:ss {#mid-server-parameters__ul_l1s_3t5_b3b} mid.disable_amb : Disables the Asynchronous Message Bus (AMB) notifications for new ECC queue output messages. For more information, see the Asynchronous Message Bus section in[Asynchronous Message Bus](https://servicenow-prod.fluidtopics.net/MiXcR9G3ui5Vkc~Z2ld0iQ#ecc-queue-mid-server__section_b5j_ysv_s1b). When AMB is enabled the MID Server uses a different default polling interval than when AMB is disabled. See the mid.poll.time parameter for more details. If you set a polling interval with the mid.poll.time parameter, the MID Server uses that value whether or not the AMB client is enabled. * Type: true \| false * Default value: false {#mid-server-parameters__ul_jk5_jt5_b3b} mid.https.truststore.password : Sets the trustStore password that is required for HTTPS connections with the Asynchronous Message Bus (AMB) Client. * Type: string * Default value: none {#mid-server-parameters__ul_hhn_4t5_b3b} mid.https.truststore.path : Path to the trustStore to be used by the MID Server for TLS transactions (Asynchronous Message Bus (AMB) Client). Add this parameter only if you want to change the default path. * Type: string * Default: Path to the JRE trustStore bundled with the MID Server {#mid-server-parameters__ul_ajn_pt5_b3b} mid.instance.skip_basic_auth : Allows the MID Server to connect to an instance using cookies instead of basic authentication credentials. When set to true, it uses cookies first. However, if the connection fails, the MID Server will try to connect again using basic authentication credentials. * Type: true \| false * Default value: true {#mid-server-parameters__ul_dct_svy_1jb} mid.jmx.enabled : Enables a JMX server on the MID Server, which exposes some management information to JMX consoles. Implementing JMX requires additional configuration of the Java runtime environment. Setting this parameter to true is only recommended for those with detailed knowledge of the Java security architecture and a specific need for JMX. * Type: true \| false * Default value: false {#mid-server-parameters__ul_xxd_tt5_b3b} mid.poll.time : Sets the default MID Server polling interval (in seconds). The polling interval is the amount of time the MID Server waits before checking the ECC queue for work when the MID Server is not busy. For more information, see the Asynchronous Message Bus section in. When mid.disable.amb is set to false (the default setting), see the Asynchronous Message Bus section in [Asynchronous Message Bus](https://servicenow-prod.fluidtopics.net/MiXcR9G3ui5Vkc~Z2ld0iQ#ecc-queue-mid-server__section_b5j_ysv_s1b) for more information about how mid.poll.time is used. When mid.disable.amb is set to true, polling occurs on a fixed mid.poll.time interval, but polling switches to using mid.poll.time.standard (5 seconds by default) when the MID Server is busy. * Type: integer (seconds) * Default value: 40 when mid.disable.amb is false, or 5 when mid.disable.amb is true. {#mid-server-parameters__ul_odz_tt5_b3b} mid.probe.wait.resources : Indicates whether probe execution is delayed until resources are available. Used to enable [MID Server Resource Reservation](https://servicenow-prod.fluidtopics.net/7UaT9i0RdbN_pF1iB6hJtg#mid_server_resource_reservation "This feature allows resources to be reserved before a task is assigned to a thread. If the resources the task needs aren’t available, then that task waits in the MID Server work queue while other tasks are assigned to the thread."). Hinweis: Requires MID Server restart. * Type: true \| false * Default value: true {#mid-server-parameters__ul_s2f_pfp_plb} mid.property.long_runner : Identifies the name of a script include that manages long running commands. Hinweis: This property is applicable till the Rome version only. If your instance is of a later version, you must configure the system property, glide.eccprobe.longrunner.class. * Type: string * Default value: LongRunner {#mid-server-parameters__ul_gqs_jlh_ppb} threads.interactive.max : Sets the maximum number of interactive worker threads that can run simultaneously in the interactive thread pool. See [Set MID Server Thread Use](https://servicenow-prod.fluidtopics.net/ptcKRw8McyzYO8lpq1Vafg "Change the number of threads used by the MID Server according to performance requirements. MID Servers which compete with other programs for CPU time can use fewer threads than the default. MID Servers which need more speed, and have a host computer powerful enough, can use more threads."). * Type: integer * Default value: 10 {#mid-server-parameters__ul_ik2_355_b3b} threads.expedited.max : Sets the maximum number of expedited worker threads that can run simultaneously in the expedited thread pool. See [Set MID Server Thread Use](https://servicenow-prod.fluidtopics.net/ptcKRw8McyzYO8lpq1Vafg "Change the number of threads used by the MID Server according to performance requirements. MID Servers which compete with other programs for CPU time can use fewer threads than the default. MID Servers which need more speed, and have a host computer powerful enough, can use more threads."). * Type: integer * Default value: 20 {#mid-server-parameters__ul_e5x_t1v_rjb} threads.max : Sets the maximum number of standard worker threads that can run simultaneously in the standard thread pool. This parameter provides direct control over what CPU resources the MID Server consumes on the computer that hosts it. See [Set MID Server Thread Use](https://servicenow-prod.fluidtopics.net/ptcKRw8McyzYO8lpq1Vafg "Change the number of threads used by the MID Server according to performance requirements. MID Servers which compete with other programs for CPU time can use fewer threads than the default. MID Servers which need more speed, and have a host computer powerful enough, can use more threads."). * Type: integer * Default value: 25 {#mid-server-parameters__ul_cly_355_b3b} Wichtig: You can set threads.max as high as 200, however, this setting may need to be changed depending on the OS. For example, Windows-based MID Servers running Discovery uses Powershell which is resource intensive. In this case, you may exhaust the CPU power of the host machine with just 50 threads count. ## Credentials parameters {#mid-server-parameters__section_credentials} mid.aws.instance_profile_name : Name of the AWS IAM role configured on the EC2 instance. When configured, the MID Server uses the temporary credentials granted to this role by the AWS instance profile to Discover cloud resources. * Type: string * Default value: None (User must provide a non-blank value) {#mid-server-parameters__ul_pvm_ypp_b3b} mid.credentials.provider : Specifies the Java class name of the credentials provider. * Type: string * Default value: com.service_now.mid.creds.standard.StandardCredentialsProvider {#mid-server-parameters__ul_cqw_ypp_b3b} mid.secure_credentials.key_pairs.provider : Class that the MID Server uses to generate secure key pairs. * Type: string * Default value: com.service_now.mid.keypairs.provider.standard.StandardKeyPairsProvider {#mid-server-parameters__ul_lsg_zpp_b3b} ## Debug parameters {#mid-server-parameters__section_debug} debug.logging : \[Deprecated\] Specifies whether to enable logging of MID Server events and messages (both sent and received). Normally this parameter is only used by developers, but it is occasionally useful when troubleshooting a problem. Be aware that setting this parameter to true causes intensive logging on the MID Server, potentially using considerable disk space. * Type: true \| false * Default value: false {#mid-server-parameters__ul_cmf_m55_b3b} This parameter has been replaced by the mid.log.level parameter. debug : \[Deprecated\] Specifies whether to enable debug logging on the MID Server. Normally this parameter is only used by developers, but it is occasionally useful when troubleshooting a problem. Be aware that setting this parameter to true causes intensive logging on the MID Server, potentially using considerable disk space. * Type: true \| false * Default value: false {#mid-server-parameters__ul_vds_m55_b3b} This parameter has been replaced by the mid.log.level parameter. file.probe.template.debug : Specifies whether to debug file probe templates. * Type: true \| false * Default: false {#mid-server-parameters__ul_imh_n55_b3b} mid.cim.debug : Specifies whether to enable debug logging for CIM, WBEM, SLP, or SMI-S. * Type: true \| false * Default value: false {#mid-server-parameters__ul_mx1_455_b3b} mid.ssh.debug : Enables SSH debug information in the log file. The parameter usage depends on whether the ServiceNow SSH client is enabled. When the ServiceNow SSH client is enabled, the parameter functions as follows: * Type: string * Default value: falseThe following string values are valid for the ServiceNow SSH client: * true: Enables SSH debug information in the log file. * false: Disables SSH debug information in the log file. * \: Specify which IP ranges to enable SSH debug information in the log file. You can enter IP addresses in the following formats: * An IP range defined by a slash and the number of bits in the subnetwork. For example, the string 10.10.10.0/24 scans 24 bits of IP addresses from 10.10.10.0 to 10.10.10.254. * An IP range defined by a dash. For example, the string 10.10.11.0-10.10.11.165 scans the IP addresses from 10.10.11.0 to 10.10.11.165. * A comma-separated list of specific IP addresses. For example the string 10.10.11.200,10.10.11.235 scans the IP addresses 10.10.11.200 and 10.10.11.235. {#mid-server-parameters__ul_cld_v55_b3b} * deferred: Logs SSH debug information in memory unless an error or warning occurs. If an error or warning occurs, the platform publishes the debug information to the log file. This ensures that only the part of the log file pertaining to the error or warning is recorded. If no error or warning is detected, the platform deletes the unused log data from memory when the session closes. Each session stores up to 1000 log messages. If the session exceeds 1000 log messages, the deferred log discards the oldest log message to make room for the newest log message. {#mid-server-parameters__ul_bld_v55_b3b} {#mid-server-parameters__ul_ald_v55_b3b} When the ServiceNow SSH client is disabled, the parameter enables or disables SSH debug information in the log file: * Type: true \| false * Default value: false {#mid-server-parameters__ul_dld_v55_b3b} Hinweis: The MID Server parameter mid.ssh.debug only affects SNCSSH and J2SSH. To enable Maverick client debug logging, set the MID Server configuration parameter mid.log.level to `debug, com.maverick=debug`. mid.log.level : Specifies the logging level for the MID Server. Possible values are: * debug * info * warn * error {#mid-server-parameters__ul_w4z_v55_b3b} Hinweis: Values are case insensitive. * Type: string * Default value: info {#mid-server-parameters__ul_x4z_v55_b3b} mid.http.idle_connection_monitor.debug : Enables debug logging for the Idle Connection Monitor. * Type: true \| false * Default value: false {#mid-server-parameters__ul_rms_w55_b3b} ## DNS parameters {#mid-server-parameters__section_dns} mid.dns_scan.regulator.interval_ms : Specifies the interval between DNS scans in milliseconds. * Type: integer * Default value: 10 {#mid-server-parameters__ul_cdz_z55_b3b} mid.dns_scan.regulator.packets_per_interval : Specifies the number of regulator packets per DNS scan. * Type: integer * Default value: 1 {#mid-server-parameters__ul_tjk_1v5_b3b} mid.dns_scan.default_name_servers : Specifies the host names or IP addresses of the default name servers. * Type: string * Default value: none {#mid-server-parameters__ul_jsw_1v5_b3b} mid.dns_scan.default_name_servers : Specifies the host names or IP addresses of the default name servers. * Type: string * Default value: none {#mid-server-parameters__ul_lxj_bv5_b3b} mid.dns_scan.additional_name_servers : Specifies the host names or IP addresses of any additional name servers. * Type: string * Default value: none {#mid-server-parameters__ul_qrf_cv5_b3b} mid.dns_scan.load_balancing_enable : Specifies whether to enable load balancing of name servers. * Type: true \| false * Default value: false {#mid-server-parameters__ul_hnk_dv5_b3b} mid.probe.use_legacy_forward_dns : Enables the legacy DNSNameResolver probe and disables the default DNSNameResolver probe. See [Probes used by Orchestration](https://www.servicenow.com/docs/access?context=r_OrchestrationProbes&version=australia&pubname=australia-integrate-applications&ft:locale=en-US) for more information. * Type: true \| false * Default value: false {#mid-server-parameters__ul_jxz_dv5_b3b} mid.probe.use_legacy_reverse_dns : Enables the legacy DNS probe and disables the default DNS probe. If you experience problems with the features of the default DNS probe, use this parameter to disable those features. The default DNS probe's features include being lightweight and faster due to executing in parallel, while the legacy probe is throttled by the MID Server because it executes in serial. The default probe utilizes DNS lookup by the MID Server host OS to make use of the OS maintained DNS cache, while the legacy probe does not. Consequently, after a DNS lookup by the default probe fails in Windows systems, the OS also tries looking up by NETBIOS name. * Type: true \| false * Default value: false {#mid-server-parameters__ul_hmv_hv5_b3b} ## Event Management parameters {#mid-server-parameters__section_event-management} mid.probe.event.bulk_size : Specifies the maximum size of an event payload, in MB. * Type: integer * Default value: 120 {#mid-server-parameters__ul_bzd_mv5_b3b} mid.probe.event.wait_time : Waiting period on an empty queue for sending events. * Type: integer * Default value: 1000 {#mid-server-parameters__ul_oyn_mv5_b3b} mid.probe.event.send.enabled : Enables or disables the sending of events. * Type: true \| false * Default value: true {#mid-server-parameters__ul_qwz_mv5_b3b} mid.probe.event.queue.max_size : Specifies the maximum size permitted for the event queue before incoming events are rejected. * Type: integer * Default value: 100,000 {#mid-server-parameters__ul_jml_nv5_b3b} mid.probe.event.max.retry_time : The maximum number of seconds MID retries sending events. * Type: integer * Default: 1800 {#mid-server-parameters__ul_w4l_z2x_n4b} mid.probe.event.queue.use_bulk : Specifies whether events are sent to the server singly or in bulk.

Apply this parameter to each MID Server used with event connector instances. Choices are: all : This setting removes all whitespaces. leave_as_is : This setting keeps all whitespaces. keep_newline : This setting keeps only new_line and removes all other whitespaces. * Type: string * Default: all {#mid-server-parameters__ul_n32_qv5_b3b} mid.em.metric.metric_to_ci_map_limit : Specifies the maximum number of active metrics allowed per CI map. * Type: integer * Default value: 200,000 {#mid-server-parameters__ul_zsz_qv5_b3b} mid.em.metric_binding_timeout_seconds : Specifies the number of seconds to wait before resending unhandled events * Type: integer * Default value: 300 {#mid-server-parameters__ul_q5s_rv5_b3b} mid.em.metric_binding_timeout_max_seconds : Specifies the maximum number of seconds to wait before resending unhandled events. * Type: integer * Default value: 10800 {#mid-server-parameters__ul_jdq_sv5_b3b} mid.em.metric_max_elapsed_time_before_refresh : Specifies the maximum number of seconds before the metric source type cache is refreshed in memory. * Type: integer * Default value: 60 {#mid-server-parameters__ul_c4v_tv5_b3b} mid.em.matric_max_sql_string_length_for_types : Specifies the maximum length of the string (composed of types) used for an SQL command * Type: integer * Default value: 30000 {#mid-server-parameters__ul_znm_vv5_b3b} mid.em.statistics_report_perioon_sec : Specifies the period, in seconds, between statistics reports to the instance. Use 0 to disable reporting. This parameter requires a restart. * Type: integer * Default value: 60 {#mid-server-parameters__ul_k5k_wv5_b3b} mid.em.metric_connector_max_run_time_seconds : Specifies the maximum number of seconds to collect metrics in every cycle. * Type: integer * Default value: 300 {#mid-server-parameters__ul_oyt_yv5_b3b} mid.em.metric_connector_history_min : Specifies the number of minutes to go back in history to retrieve metrics. * Type: integer * Default value: 180 {#mid-server-parameters__ul_fwv_gw5_b3b} mid.em.metric_event_logging : Specifies the level of metric and event logging. Choices are: * none * all * events * metrics * metrics:\ * events:\ {#mid-server-parameters__ul_nps_hw5_b3b} * Type: string * Default value: none {#mid-server-parameters__ul_ops_hw5_b3b} mid.em.metric_connector_late_arrivals_delay : Specifies the number of seconds to delay when collecting metrics. * Type: integer * Default value: 30 {#mid-server-parameters__ul_rhv_3w5_b3b} ## FTP connection parameters {#mid-server-parameters__section_ftp-connection} mid.ftp.max_pool_size : Specifies the maximum size of the FTP Connection Pool, in megabytes. * Type: integer * Default value: 25 {#mid-server-parameters__ul_mgs_crp_b3b} mid.ftp.max_per_target : Specifies the maximum number of the FTP connections per target. * Type: integer * Default value: 5 {#mid-server-parameters__ul_v5b_drp_b3b} mid.ftp.max_conn_idle_time : Specifies the maximum amount of time, in milliseconds, that an FTP connection can sit idle in the pool. * Type: integer * Default value: 300000 {#mid-server-parameters__ul_l4l_drp_b3b} mid.filesystem.max.ls : Specifies the maximum number of files that can be returned in the filesystem list directory command. * Type: integer * Default value: 10000 {#mid-server-parameters__ul_ac1_2rp_b3b} ## Logging parameters {#mid-server-parameters__section_logging} disable_monitors : Specifies whether to disable the MID Server from actively checking for monitors on the instance. * Type: true \| false * Default value: true {#mid-server-parameters__ul_p11_zqp_b3b} mid.show.queries : Instructs the MID Server whether to log details about every query it makes to the ServiceNow instance. Typically this parameter is only used by developers, but it is occasionally useful when troubleshooting a problem. Be aware that setting this parameter to true causes intensive logging on the MID Server, potentially using considerable disk space. * Type: true \| false * Default value: false {#mid-server-parameters__ul_rbk_zqp_b3b} disable.remote.logging : Prevents the MID Server from logging any information to the MID Server log on the instance.

For more information, see [MID Server privileged commands](https://servicenow-prod.fluidtopics.net/wiZ0usMr7e9KjcSsNjCZIQ#c_PrivilegedCommandsForMIDServer "To discover certain information on a host server, the MID Server must run SSH commands with higher privileges. The platform provides default privileged commands for the MID Server to use and the ability to add additional commands to the system."). The remainder of this section only applies to targets which run sudo. When this parameter is set to true, the MID Server assumes that the user configured in the credential has the privilege to run the given command using sudo. The MID Server assumes the target user can run any command string following sudo on the target. When this parameter is set to false, the MID Server runs "sudo -l" on the target to verify the command which follows sudo has permission to run on the target. Regardless of this parameter's value, the MID Server always validates that sudo by itself can be run on the target. Some releases do not show this parameter in the MID Configuration Parameters pull down list. In this case, you may optionally add this parameter in MID Properties. * Type: true \| false * Default value: false {#mid-server-parameters__ul_gcl_s3g_sbb} ## Upgrade parameters {#mid-server-parameters__section_upgrade} mid.pinned.version : Name of the version to which this MID Server is pinned. * Type: string * Default value: MID buildstamp Hinweis: To see the MID buildstamp for your instance, type stats.do in the navigation filter.

A setting of true directs the MID Server to run probes with the Windows credentials from the credentials table. To run probes with the credentials of the user for the MID Server service, set this parameter to false. * Type: true \| false * Default value: true {#mid-server-parameters__ul_kkh_js4_b3b} mid.powershell.path : Enables an administrator to point to a specific PowerShell on a MID Server in cases where more than one PowerShell is installed. Supply the path to the folder containing the PowerShell executable, for example, C:\\mypowershell or C:\\mypowershell\\. ServiceNow automatically appends the string powershell.exe to the path. Configure this parameter when both a 32-bit and 64-bit PowerShells are active on the same MID Server, and it becomes necessary to launch the correct PowerShell for the context. 64-bit Windows employs file system redirection and the MID Server runs as a 32-bit application. If trying to specify a path in %WinDir%\\System32, Windows automatically redirects to %WinDir%\\SysWOW64. To avoid redirection, specify the path as %WinDir%\\Sysnative. For example, instead of C:\\WINDOWS\\system32\\WindowsPowerShell\\v1.0\\, specify C:\\WINDOWS\\sysnative\\WindowsPowerShell\\v1.0\\. Hinweis: On a 64-bit version of Windows XP, a Microsoft hotfix may be required to enable this. To discover applications running on a 64-bit Windows machine, the MID Server must be running on a 64-bit Windows host machine. * Type: string (path) * Default value: none {#mid-server-parameters__ul_pxw_ls4_b3b} mid.powershell.enforce_utf8 : Enable this parameter to force commands on a target Windows system to return UTF-8 encoded output.

Navigate to AllMID ServerServers. 2. From the list of MID Servers, select a MID Server to configure. 3. Select the Configuration Parameters related list. This shows all the parameters currently in the MID Server's configuration file. If there are any passwords, they are displayed in asterisks for security reasons. See [MID Server parameters](https://servicenow-prod.fluidtopics.net/VYH5xHLIPq1GhC9qbQDc9Q#mid-server-parameters "Parameters control the behavior of a particular MID Server and have lower precedence than MID Server properties.") for a list of available parameters. Abbildung : 1. Defining MID Server configuration parameters 4. To add parameters, click New, and then complete the form. After the form is submitted, the configuration file for that MID Server is modified to include the new parameter. Changes to existing parameters are reflected in the MID Server configuration file as well. Changes made to the MID Server configuration file do not take place immediately, but rather the next time the MID Server is restarted. The MID Server form has a related link for restarting the MID Server. Hinweis: ServiceNow prevents you from saving changes, such as modifying or deleting parameters, that would cause the MID Server to lose communications with the instance. For example, you cannot change the url parameter. Any changes to these protected parameters must be made directly in the config.xml file for that MID Server. 5. **Wahlweise:** Set parameters in the config.xml file. MID Server configuration is controlled by an XML file called config.xml. This file is located in the /agent directory, in the MID Server isntallation directory. You can edit this file directly to make any configuration changes to protected parameters. Many configuration changes, such as those that do not disrupt communication between the MID Server and the ServiceNow instance, may also be made from the instance. The structure of the config.xml file is simply an outer parameters tag and a series of inner parameter tags. Each parameter tag has name and `value` attributes. * To change the value of a parameter, edit the value attribute. * To add a parameter, add another parameter tag with its name and value. * To delete a parameter, delete the entire parameter tag. {#t_SetMIDServerParameters__ul_sp1_34d_xp} The order of the parameters within the file is not important. Notice the green comment sections in the sample. Use these elements to add useful comments to the configuration file. Hinweis: When configuring the MID Server for use with a proxy server, be sure to remove the comment tags around the proxy sections that you configure. Abbildung : 2.
