Issue/Introduction
A customer may see errors in their iDash server logs showing that there were issues with heap space or ran out of heap space such as the following:
<timestamp> [ERROR] idashdb-config-thread-6:com.ca.idash.core.db.idashdb.DbConfigTool$1: java.lang.OutOfMemoryError:Java heap space
com.ca.idash.core.exception.IdashException: java.lang.OutOfMemoryError:Java heap space
Environment
Component:
Resolution
Navigate to $IDASH_HOME/bin and open the idash_server file for editing.
Find the JAVA_OPTS line and modify the values for the parameters -Xms which is minimum java heap allowed for the jvm and -Xmx which is maximum java heap allowed for the jvm.
Save the file.
Restart the iDash server using the idash_server stop and idash_server start commands.
Additional Information
Notes:
1. These values are by default in megabytes (hence the m at the end of the value).
2. There can be no spaces between the parameter and the value.
3. -Xmx value cannot be the same as the available system memory. We need to leave some memory for the system to function.
See iDash "System Requirements" doc below.
