In this post, sharing the difficulties of boucing Apache, clearing HTML comparing with 11i.
To clear HTML cache and bounce Apache at R12 level, firstly goto the scripts directory of R12
To clear HTML cache :
The _pages directory under $COMMON_TOP should not be cleared for E-Biz R12, which we used to do in 11i applications. For clearing middle tier cache in R12,
Navigate to Functional Administrator responsibility > Core Services >
Caching Framework > Global Configuration > Clear cache
Instead of clearing the _pages in R12 creates blank login page issue, as in R12 the jsp files does not get compiled automatically.
At R12 level bouncing apache command is different of the one to bounce oacore oc4j engine andothers.
An example of situation is : how to make a modification to a JSPand have that modification recognized by the OC4J - JSP engine.
In 11i the apache start and stop command, also bounce the JVM running on JSERV and clear caches by doings as below :
To clear the jsp & modplsql caches run this command
rm -Rf $OA_HTML/_pages/*
rm -Rf $COMMON_TOP/_pages/*
rm -Rf $IAS_ORACLE_HOME/Apache/modplsql/cache/*
But in R12 the command to stop and start apache only takes action on Apache web server and not on the OC4J container that executes the JVM.
To bounce the OC4J container there is an specific script:
Therefore when making a modification to a JAVA class in R12 for the web application, in order to have that change recognized, it is needed to bounce
OC4J using adoacorectl.sh script.
Bouncing oacore OC4J engine may also be needed if you make modifications to system properties.
Example for JTT based applications: jtt system properties.
