One of the trainee from our previous batch encountered issue while accessing\u00a0the oamconsole URL: \u00a0 http\/\/<Hostname>:<Admin Port>\/oamconsole.<\/span><\/p>\n

To find the root cause check the Admin Server log file located at\u00a0$DOMAIN_HOME\/servers\/AdminServer\/logs\u00a0<\/span><\/strong>and in our case, it was showing below error messages:<\/p>\n

Root Cause<\/span><\/strong>:<\/p>\n

Since, Admin Console is deployed on Admin Server and is accessible via Admin Port \/oamconsole (\u00a0http\/\/<Hostname>:<Admin Port>\/oamconsole)<\/span>\u00a0<\/span><\/p>\n

\"oam_admin\"<\/a><\/p>\n

The jvm size at the moment \u00a0was 500 MB for Admin Server, it should be in between 1Gb to 2Gb , because we access OAM console on top of admin server.<\/p>\n

Solution<\/span>:<\/strong><\/p>\n

Temporary Fix:<\/strong><\/span><\/p>\n

Bounce the Admin server.<\/p>\n

Permanent Fix:<\/span><\/strong><\/p>\n

1. Change the Admin server jvm settings as shown below in\u00a0setDomainEnv.sh<\/strong> script located under $DOMAIN_HOME\/bin<\/strong>.<\/p>\n

if [ “${SERVER_NAME}” == “AdminServer” ] ; then<\/span><\/p>\n

\u00a0\u00a0\u00a0\u00a0\u00a0 MEM_ARGS=”-Xms2048m -Xmx2048m -XX:PermSize=128m -XX:MaxPermSize=\u00a0\u00a0<\/span><\/p>\n

\u00a0\u00a0\u00a0\u00a0\u00a0 512m”<\/span><\/p>\n

\u00a0\u00a0\u00a0 \u00a0\u00a0export MEM_ARGS<\/span><\/p>\n

fi.<\/span><\/p>\n

2. Bounce the Admin server and you should be able to access the OAM console.<\/p>\n

Note:<\/span><\/strong> You can see the modified jvm settings in Admin server Log.<\/p>\n
