I don't think your problem is related to switching db from NOARCHIVELOG to ARCHIVELOG.
You are unable to startup the instance because you are running out of semaphores. Try increasing the kernel parameter "semmns".

Thanks Sanjay..Yeah I also think its the problem with semaphores.Could you give me any suggestion for the setting the parameters

SEMMNS, SEMMSL,SEMNI.

Right now it is with the default values.

The Processes parameter in the init.ora file is 100.

OS is HP-UX.
