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.
Timezone settings are not set correctly.
Find the timezone knowledge of the operating system.
bash-3.00$ echo $TZ
Stop EM services.
$emctl stop dbconsole
Make the agentTZRegion = XXXXX line in the “$ORACLE_HOME/<servername>_<sid>/sysman/config/emd.properties” file the same as the timezone information of the operating system.
Restart EM services.
$emctl start dbconsole
