# Set proxy server memory limits

# Set the proxy server initial memory limit and upper bound memory limit {#ariaid-title1}

Set the initial memory limit and upper bound memory limit to specify how much memory
the proxy server can consume. Set these limits to avoid performance issues in your Edge Encryption implementation.

## Vorbereitungen

Role required: admin

## Warum und wann dieser Vorgang ausgeführt wird

As a guideline, set both the initial memory limit and the upper bound memory limit to
the same value. On any machine, allocate 2 GB of the physical memory to the
operating system (OS). Then allocate the rest of the physical memory to the heap
using the initial memory limit and upper bound memory limit properties. For example,
on a machine with 8 GB of memory, allocate 2 GB to the OS, and allocate the
remaining 6 GB (6144 m) to the initial and upper bound memory.  
Wichtig:  
If your Edge Encryption proxy server is running, you must stop and restart the proxy server after updating these properties.

## Prozedur

1. In your proxy server directory, open \<install dir\>/conf/wrapper.conf.
2. To set the initial memory limit, add the following line at the end of the file:  

       wrapper.java.additional.<number>=-Xms<min_memory_in_MB>m

   Set `<number>` to the next available
   `<number>` in the sequence of
   `wrapper.java.additional.<number>` properties defined
   in the `wrapper.conf` file.  
   For example, you have the following list of `wrapper.java.additional.<number>` properties:

       wrapper.java.additional.1=
       wrapper.java.additional.2=

   The maximum `<number>` in the above list is 2. When you add the `wrapper.java.additional.<number>=-Xms<min_memory_in_MB>m` line, set `<number>` to 3, the next available number.  
   Wichtig:  
   Do not leave gaps in the numbering sequence.  
   Set `<min_memory_in_MB>` to the number of megabytes of
   memory remaining after allocating 2 GB of memory to the OS.
3. Set the upper bound memory limit.  
   Because an upper bound memory limit is not set in the base system, the proxy server can use all available memory. If other services are running on the server, you may want to set the upper bound memory limit.

   Add the following
   line at the end of the
   file:

   `wrapper.java.additional.<number>=-Xmx<max_memory_in_MB>m`

   Set
   `<number>` to the next available
   `<number>` in the sequence of
   `wrapper.java.additional.<number>` properties defined
   in the `wrapper.conf` file.  
   For example, you have the following list of `wrapper.java.additional.<number>` properties:

       wrapper.java.additional.1=
       wrapper.java.additional.2=

   The maximum `<number>` in the above list is 2. When you add the `wrapper.java.additional.<number>=-Xmx<max_memory_in_MB>m` line, set `<number>` to 3, the next available number.  
   Hinweis:  
   Do not leave gaps in the numbering sequence.  
   Set `<max_memory_in_MB>` to the number of megabytes of
   memory remaining after allocating 2 GB of memory to the OS.
4. Save and close the file.

## Example: Setting proxy server initial and upper bound memory limits

    wrapper.java.additional.1 = -Djava.io.tmpdir=../tmp
    wrapper.java.additional.2 = -Dcloudedge.home.dist=..
    # must ensure UTF8 encoding when running on Windows
    wrapper.java.additional.3 = -Dfile.encoding=UTF8
    # additional properties for heap settings
    wrapper.java.additional.4 = -Xms6144m
    wrapper.java.additional.5 = -Xmx6144m
