Hi
We have issue starting up our db instance.
SQL> startup
ORA-01012: not logged on
Process ID: 0
Session ID: 0 Serial number: 0
and
Total /dev/shm size: 15087755264 bytes, used: 11739136 bytes
Shared Memory:

309854210 0x00000000
309886979 0x00000000
309821441 0x00000000
309919748 0xd9f9bcac
Semaphores:

458756 0x92743d85

Oracle Instance not alive for sid "PPPP"
What steps can we perform to know which Shared Memory ID to remove the orphaned shared memory segment ?
Any help is appreciated
