You can use script files, infasetupconfig.sh and infaserviceconfig.sh, to set environment variables. You can find the script files in the following location:

<CDI-PC installation directory>/Informatica/platform/usr/bin/

If you use environment variables such as INFA_JAVA_OPTS or INFA_JAVA_CMD_OPTS to set customized values for JVM parameters that infaservice and infasetup commands use, set the variables and values in the configuration file for each command.

For example, to set the maximum heap size to 4 GB for each of the commands, configure each file as follows:

infaserviceconfig.sh.
INFA_JAVA_OPTS="-Xmx4096m -XX:MaxMetaspaceSize=256m ${INFA_JAVA_OPTS}"
infasetupconfig.sh.
INFA_JAVA_CMD_OPTS="-Xmx4096m -XX:MaxMetaspaceSize=128m ${INFA_JAVA_CMD_OPTS}"
