The Master, Application Server (AJAS), and Integration Servers (IS') function each within their own Java Virtual Machine with default arguments. To improve performance for your specific TSIM deployment, it might be useful to configure the JVM and Java options. TSIM provides a means of configuring the Java Virtual Machine (JVM) and Java options for each of them in the following properties files:

Master: $ACTISEDI/lib/ediman.jdbc

Parameter: JMASTER_OPTS

Note: This parameter should be written before the last "if - else" condition of the file.

Example: JMASTER_OPTS="-Xmx512m -Xms256m -XX:+UseConcMarkSweepGC"

AJAS: $ACTISEDI/param/startajas.par

Parameter: MEM_OPT

Example: MEM_OPT="-Xms64m -Xmx4096m -XX:NewSize=32m"

IS instances: $ACTISEDI/is/instances/is#/etc/java.properties

Parameter: MEM_OPT

Note: If there are more IS instances, each will have their separate properties file.

Example: MEM_OPT="-Xms128M -Xmx2048M"

The configuration specified in these files is taken into account each time the respective process is started.
