Clear Cache in Oracle EBS R12

Clear Cache in Oracle EBS R12

There are two ways to clear cache in R12

1. Functional level (individual product/all product cache)

Functional Administrator -> Core Services -> Caching Framework -> Global Configuration ->

“Go to specific cache or Clear All Cache“

2. Server level

Basic steps for a clear cache bounce is as below:-

Set you application environment and go to $ADMIN_SCRIPTS_HOME

1. ./adopmnctl.sh stopall
2. wait for command to complete
3. ./adopmnctl.sh status -l
4. cd $COMMON_TOP/_pages
5. ls -l|wc -l (note it down)
6. rm -rf * (to remove all files)
   Note:-For step 4 to 6, better to take backup of _pages by renaming it, and create a new directory as _pages at the same place.
7. ls -l|wc -l (it should be 0 now)
8. cd $FND_TOP/patch/115/bin
9. which perl (should come from $IAS_ORACLE_HOME/perl/bin)
10. pl –compile –flush -p 10 (to compile all JSPs,-p is for parallel and value (i.e. 10 here) can be varied accourding to your server)
11. wait for successful completion
12. cd $COMMON_TOP/_pages
13. ls -l| wc -l (check whether count is same or more than before (pre-remove) – sometimes a little difference may be there)
14. Go to $ADMIN_SCRIPTS_HOME again
15. ./adopmnctl.sh startall
16. wait for proper services startup
17. ./adopmnctl.sh status -l
18. check front-end and JSPs and FORMs should open up fine

Now change in R12 context file (XML file):

parameter s_jsp_main_mode – you will find it justrun by default.

change it to – recompile and run autoconfig to make the changes take place.

This will generate the jsp at run time saving bounce time, but could affect the performance.
