Finalize and validate the upgrade

Follow these steps to perform the final tasks for an upgrade to Moogsoft Enterprise v7.3.x from v7.0.x, v7.1,.x or 7.2.x.

Refer to Upgrade Moogsoft Enterprise for general information and upgrade instructions for other components and versions.

Configure the ServiceNow MID server to use Java 8

Configure Elasticsearch heap size

The minimum and maximum JVM heap sizes must be large enough to ensure that Elasticsearch starts.

To set the minimum and maximum JVM heap sizes:

  • For RPM, edit the /etc/elasticsearch/jvm.options file.

  • For Tarball, edit the $MOOGSOFT_HOME/etc/cots/elasticsearch/config/jvm.options file.

These heap sizes must be the same value. For example, to set the heap to 4 GB:

# Xms represents the initial size of total heap space
# Xmx represents the maximum size of total heap space

-Xms4g
-Xmx4g

If you change the heap size, you must restart Elasticsearch:

  • For RPM, run service elasticsearch restart.

  • For Tarball, run $MOOGSOFT_HOME/bin/utils/process_cntl elasticsearch restart.
