The system properties available in Developer Sandboxes govern application behavior, enabling developers to configure and optimize their testing environments effectively.
Nota:  
To open the System Properties \[sys_properties\] table, enter <kbd class="ph userinput">sys_properties.list</kbd> in the navigation filter.  
These properties are available for Developer Sandboxes.{#dsb-properties-installed__table_ek4_ct3_xhc__entry__3}

| Property | Description | Details |
|-|-|-|
| glide.dev_sandbox.num.controller | Number of nodes that run as a controller. * Type: number * Default value: 2 {#dsb-properties-installed__ul_fk4_ct3_xhc} | * Can't be 0. * Increasing converts unassigned nodes to controller nodes. * Decreasing converts unassigned nodes to nodes. * More controller nodes mean you get fewer sandboxes. {#dsb-properties-installed__ul_k5r_1z3_xhc} |
| glide.dev_sandbox.node.healthy_time_min | Time in minutes that a node is considered healthy. An unhealthy node that's assigned to a sandbox can be remediated by assigning it to another sandbox. Remediation is the process of detecting a sandbox that should be running on a node but isn't, and then assigning another node to run on the sandbox. * Type: number * Default value: 10 {#dsb-properties-installed__ul_blf_5y3_xhc} | * Increasing this value keeps a sandbox node up longer, so remediation happens less frequently. * Decreasing it takes a node down faster, so remediation occurs more frequently. * Do not set this value lower than the time it takes a node to restart, roughly 3 minutes. During a restart, the node is still considered healthy to prevent the remediator from reassigning sandboxes to another node. {#dsb-properties-installed__ul_gxg_n1j_xhc} |
| glide.dev_sandbox.node.poll_interval_seconds | Number of seconds between status checks for a node expected to go offline in the sys_cluster_state table, which contains the nodes that are assigned to an instance. * Type: number * Default value: 10 {#dsb-properties-installed__ul_ptm_vy3_xhc} | * Generally doesn't need to be changed. * Used during sandbox retirement to determine how often a node is checked for being set to offline. * Increasing means the polling happens more often. * Decreasing means that the polling happens less often. {#dsb-properties-installed__ul_ebz_hbj_xhc} |
| glide.dev_sandbox.node.poll_timeout_min | Number of minutes to wait for a node to shutdown, and have a Status of Offline in sys_cluster_state table. * Type: number * Default value: 2 {#dsb-properties-installed__ul_ekj_vy3_xhc} | * Generally doesn't need to be changed. * Used during sandbox retirement to determine how long to check for a sandbox node to be set to offline. * Increasing means the polling happens longer. * Decreasing means that the polling completes faster. {#dsb-properties-installed__ul_knb_kcj_xhc} |
| glide.dev_sandbox.default_table_config | Default table config in Developer Sandboxes. * Type: string * Default value: shared_table * Other possible values: * shared_table * full_copy * zero_copy {#dsb-properties-installed__ul_l2f_vy3_xhc} {#dsb-properties-installed__ul_k2f_vy3_xhc} | * The full_copy value isolates tables but uses much more database space and can make sandbox creation slower, especially with large datasets. * The zero_copy value also isolates tables with less initial disk space, but starts empty and may consume more space as data is added. {#dsb-properties-installed__ul_i2k_bsj_xhc} |
| glide.dev_sandbox.dsb_db_copier_threads | Number of concurrent table creations in a sandbox. * Type: number * Default value: 1 * Other possible values: 1-5 {#dsb-properties-installed__ul_esd_vy3_xhc} | * Increasing threads can create more contention and load when creating sandboxes. * Aviso: Do not change this value without consulting your account manager. {#dsb-properties-installed__ul_a1y_hsj_xhc} |
| glide.db.dsb.data_copy_processor.threads | Number of data copy plans to run concurrently during sandbox creation. * Type: number * Default value: 1 * Other possible values: 1-5 {#dsb-properties-installed__ul_lcb_vy3_xhc} | * This value is multiplied by the glide.dev_sandbox.dsb_db_copier_threads value. * Increasing threads can create more contention and load when creating sandboxes. * Aviso: Do not change this value without consulting your account manager. {#dsb-properties-installed__ul_rdp_4sj_xhc} |
| glide.db.dsb.data_copy_processor.chunk_copy.threads | Number of data copiers running at a time for each table. * Type: number * Default value: 5 * Other possible values: 1-5 {#dsb-properties-installed__ul_zwm_5y3_xhc} | * This value is multiplied by the glide.dev_sandbox.dsb_db_copier_threads and glide.db.dsb.data_copy_processor.threads values. * Decreasing this value slows down sandbox creation. {#dsb-properties-installed__ul_t5k_5sj_xhc} |
| glide.dev_sandbox.cleanup_retries | Number of retries the Developer Sandboxes destroy code attempts to do clean up any leftover Developer Sandboxes tables. * Type: number * Default value: 3 {#dsb-properties-installed__ul_vfx_wyz_c3c} |   |
| glide.dev_sandbox.backup_tables | Tables that will be preserved for recreating developer sandboxes post clone. * Type: string * Default value: sys_repo_config {#dsb-properties-installed__ul_izr_kmr_c3c} | Comma-delimited list of tables to preserve. If a table has is referenced here, its content in each sandbox is saved and preserved during clones, then restored post-clone in the re-created sandbox(es). This property is effective only when Developer Sandboxes are enabled via the glide.dev_sandbox.enabled property, and impacts only sandboxes. |
| glide.dev_sandbox.export.poll_interval_seconds | Frequency in seconds that the controller node checks if a sandbox has completed exporting its altered update sets. This property is used only when exporting sandbox update sets before an instance upgrade begins. * Type: number * Default value: 10 {#dsb-properties-installed__ul_dhq_zmr_c3c} | Decreasing the value may help the upgrade go faster but at the cost of extra checks. |
| glide.dev_sandbox.export.poll_timeout_min | How long the controller node waits for a sandbox to export its altered update sets before an instance upgrade. If the timeout limit is hit, the upgrade continues regardless of export state. * Type: number * Default value: 10 {#dsb-properties-installed__ul_qlm_csr_c3c} | * Decreasing the value may result in unexported updates. * Increasing the value helps to ensure that changes are exported, but can delay the upgrade. {#dsb-properties-installed__ul_tjc_dsr_c3c} |
| glide.dev_sandbox.node.healthy_time_min | Time window in which a node must report to sys_cluster_state to be considered healthy and included in sandbox capacity calculations. * Type: number * Default value: 10 {#dsb-properties-installed__ul_lxr_xyz_c3c} |   |
| glide.dev_sandbox.lifecycle.max_concurrent_events | Maximum limit of concurrent sandbox allocations/retirements events. * Type: number * Default value: 5 {#dsb-properties-installed__ul_q1x_gsr_c3c} | Increasing the value enables more concurrent allocations/retirement, but could overload the database. |
