Increase the Java Virtual Machine (JVM) memory on Web Help Desk

You may be able to calculate the amount of memory that can be allocated to the Java Virtual Machine using the the procedure below.

1. Calculate the required allocated memory for your deployment.
2. Update the whd.conf file in the Web Help Desk directory.
3. Restart Web Help Desk. 

Calculate the required allocated memory

To configure an appropriate amount of memory for your deployment, use the following formula:
(Average # of Concurrent Techs x 150) + (Average # of Concurrent Users x 25) = MAXIMUM_MEMORY

For example, if you have 10 concurrent techs and 50 concurrent clients, the MAXIMUM_MEMORY setting in the whd.conf file should be:     
(10 x 150)1500 + (50 x 25)1250 = 2750 or 2.75GB  

MAXIMUM_MEMORY=2750

Update the whd.conf file 

Update the whd.conf file with the new memory setting. 

Microsoft Windows Server

1. Navigate to the Web Help Desk directory located at:
   C:\Program Files\WebHelpDesk\
2. Open the \conf directory.
3. Open the whd.conf file in a text editor (such as Notepad). 
4. Using the value you calculated in the previous section, change the MAXIMUM_MEMORY parameter to a value that is no greater that the total memory installed on the server. SolarWinds recommends allocating 3GB - 4 GB of memory.
5. Save and close the file. 

macOS

1. Using Finder, navigate to Applications > Utilities > Terminal and open the Terminal application.
2. Connect to the Virtual Appliance.Change the directory to the Web Help Desk conf directory:

   cd /Library/WebHelpDesk/conf

3. Enter the following command to change the maximum JVM to the appropriate value: :%s/MAXIMUM_MEMORY=512/MAXIMUM_MEMORY=[memory in MB]/ :wq
   For example,  if you would like to use 2750MB, type
   :%s/MAXIMUM_MEMORY=512/MAXIMUM_MEMORY=2750/ :wq
4. Save and close the file.

Linux/SolarWinds WHD VA

1. Connect to the Virtual Appliance (VA) using an SSH client.
2. Enter the following credentials:
   - Username: admin
   - Password: admin (default password)
   • If you changed the default password enter the new password.
   • If you do not have an SSH client and are running Windows, download a free SSH client (such as PuTTY), connect with the following credentials, and then click Open:
     • Host Name or IP: (IP of your VA)

   For example, if you want to change the value to 2750 MB, type:
   :%s/MAXIMUM_MEMORY=512/MAXIMUM_MEMORY=2750/ :wq
5. Save and close the file.
