Apache Login Issue

Hi Friends,

Today we had Prod 12.1.3 oracle applications login issue.
This issue was only to few users and other users were working fine,and this bit challenge.
We had forms/apache 6 nodes.

1)check each nodes latest access_log and error_log files

cd $LOG_HOME\ora\10.1.3\Apache\ 

If thier is any indication of failure or error

2)check each nodes application.log and server.log to fine any errors in it.

cd $LOG_HOME\ora\10.1.3\j2ee\oacore\oacore_default_group_xxx\

As said i was checking step 1.
I found one the nodes error_log file had this error

mod_oc4j: request to OC4J mt-036.us.abc.com:21506 failed: Connect failed

This indicates the issue is on this specific mt-036 node.

Bounced Apache and Oacore services on this nodes,this fixed issue

thanks,
Edwin.K
