A question on how Oracle handles shared memory segments/semaphores
CSM.DBAJul 6 2012 — edited Jul 6 2012Hi All,
I have a requirement to write a shell script to install Oracle automatically in silent mode --> create Databases and the reset script drop Databases --> deinstall Oracle
So, in the reset step, I'm removing all the Oracle related directories like software, Data files of the Database etc...without actually dropping the Database through DBCA to minimize the time required to my reset operation.
Will Oracle release the latches acquired on the shared memory segments and semaphores or I need to shut down the instance before removing the software?
In fact not Oracle particularly, any binary program which running in the machine will release it's memory structures if we remove the parent program and the required libraries needed by that program?
Thanks in advance.
regards,
CSM
