Have setup severel databases on a SuSe Enterprise Linux Server. Oracle
version is
Common for all instances is that they are correctly started at boot
time. But if one of the instances is shutdown and attempted started
again, I got an error message:
Connected to:
Oracle9i Enterprise Edition Release - Production
JServer Release - Production

SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup
ORA-27123: unable to attach to shared memory segment
Linux Error: 22: Invalid argument
Additional information: 1

SQL> startup
ORACLE instance started.

Total System Global Area 122754448 bytes
Fixed Size 451984 bytes
Variable Size 79691776 bytes
Database Buffers 41943040 bytes
Redo Buffers 667648 bytes
Database mounted.
Database opened.

The timeframe between the first and second startup is about 0.5 sec.
Any idea anyone. It seems to me that one startup attempt is used to
free up shared memory.

PS: A total of 4GB RAM on the server, 8 instances each with an sga of
about 100MB.
