Re: [suse-oracle] unable to attach to shared memory segment

at SAP I find:

- ---snip---
Check to see whether the "oracle" file exists on $ORACLE_HOME/bin, has a
size other than 0 and has the "-rwsr-s--x" authorizations.The owner must be
ora<sid>. The group is dba.

If the file is empty, you can create it again by relinking the software [...].

You can assign authorizations as well as the owner/group as follows:

chmod 6751 oracle

chown ora<sid> oracle

chgrp dba oracle

You should also check the authorization of the $ORACLE_HOME/bin directory.
This should be at "drwxr-xr-x".

Continue to ensure that the file system containing $ORACLE_HOME/bin
supports s-bit. The system must not be set to NOSUID.

Restart the system after the Oracle adjustments.If an error such as
ORA-27121 continues to occur after you set the s-bit, it may be caused by
hanging shared memories or semaphores that are assigned to the user under
whose name the Oracle database was mistakenly started until now.You can
correct this situation using tools such as ipcs/ipcrm or by rebooting.
- ---pins---

Replace ora<sid> with the name of the system user under whose account
oracle was installed, and check the files. ;-)
