[Former Member]

Hi,

I have installed ECC 6.0 on windows 32 bit. After I upgraded the kernel, the database can't be started as well as SAP. When I checked the logs, the error ORA-27101: shared memory realm does not exist was encountered.

Hi. First restart the server, then start the LISTENER, and repeat startsap again. Check if messages repeated. Regards.
