Applies to:

Oracle Applications Technology Stack – Version 11.5.9 to 12.2.2 [Release 11.5 to 12.2]

Goal

Sometimes it is recommended by Support or Development to clear Apache, Browser, Java, Jinitiator or
other caches in E-Business Suite environment. This document simply provides you with the methods to accomplish this.
The users shouldn’t be connected to the Applications during this task.

Solution

Apache / iAS

For 11i and earlier versions:

– shutdown iAS server
– go to $OA_HTML (for 11.5.9) or $COMMON_TOP (for 11.5.10.x) directory
– backup the directory _pages and delete its contents by running for instance:

rm -rf $COMMON_TOP/_pages/*

– for modplsql caches remove contents of  $IAS_ORACLE_HOME/Apache/modplsql/cache directory
– restart iAS server

To clear middle tier cache in release 12:

– go to “Functional Administrator” responsibility
– select Core Services => Caching Framework => Global Configuration => Clear cache
(please review Note 759038.1 for details).

In case you have login issue after accidentally cleared the _pages instead of using the method above for r12
please review Note 433386.1 to recompile jsp files.
