Enterprise Manager : java.lang.Exception: Exception in sending Request :: null

Error :

When we logged in to EM, there was an error “java.lang.Exception: Exception in sending Request :: null” and the page was not displayed properly.

Reason:

Timezone settings are not set correctly.

Solution:

Find the timezone knowledge of the operating system.

Stop EM services.

Make the agentTZRegion = XXXXX line in the “$ORACLE_HOME/<servername>_<sid>/sysman/config/emd.properties” file the same as the timezone information of the operating system.

Restart EM services.
