How to tune InTime Server to support more InTime Agents and jobs?

Symptoms:

Running too many InTime agents may cause the InTime Server to run out of memory.
Transferring too many large files may cause InTime Server to run out of memory.
InTime Client may experience intermittent connection issues and warnings such as: Error Message: “License server is not contactable or not responding properly. Please check with your IT administrator.”

Resolution:

Give InTime Server more memory to accommodate more agents.

By default, InTime Server runs using these jvm options:

[user@host ~]$ cat jvm.options
-server
-Xms2g
-Xmx2g
-Djava.security.egd=file:/dev/./urandom 
-Djava.net.preferIPv4Stack=true

Use <InTimeServer directory>/jvm.options.optimal to overwrite <InTimeServer directory>/jvm.options. Edit jvm.options file, update -Xms and -Xmx and restart InTime Server. In this example, -Xms and -Xmx is set to 4GB of memory. There are some cases when higher memory is required. Edit -Xms8g -Xmx8g in jvm.option when 8GB of memory is required to support higher concurrent runs.

-server
-Xms4g
-Xmx4g
-Djava.security.egd=file:/dev/./urandom
-XX:+DisableExplicitGC
-XX:+UseConcMarkSweepGC
-XX:NewRatio=2
-XX:CMSInitiatingOccupancyFraction=80
-XX:+CMSScavengeBeforeRemark
-XX:MetaspaceSize=64m 
-XX:MaxMetaspaceSize=128m
-Djava.net.preferIPv4Stack=true

(root access required) Increase the ulimit on the InTime Server machine to allow more open files. Refer to: https://support.plunify.com/en/knowledgebase/how-to-increase-file-open-limit-in-linux/

Start the InTime Server in the terminal:

[user@host intimeserver]$ ./start_server.sh

Start a new terminal and check that InTime server is running with the correct jvm options:

[user@host intimeserver]$ ps -ef | grep intimeserver
