We use WA AE release 11.3.6 along with CCS and WCC and we need to verify the exact release of EEM for troubleshooting while the EEM server is down and cannot be started.
The solution is to verify the version information in file "server.xml" (for EEM 12.x releases).
By default, you can find the "server.xml" file under the following location:
# cd /opt/CA/SharedComponents/EmbeddedEntitlementsManager/config/server
# more server.xml
You can find the equivalent information in "ipoz.conf" file for EEM 8.x releases.
