Environment: Solaris 5.9, WMQ 6.0.1.0 CMVC level p600-100-051021
While in the process of migrating a filesystem to new storage we copied data
from the old filesystem to the new filesystem - with the QM down, of course
When comparing the results, we found one difference between the old and new
filesystems.
File:: /$QM_BASEDIR/data/qmgrs/$QM/@qmpersist/spipe/ccc.7636
had permissions srwxrwx--- on the old filesystem
and permissions -rwxrwx--- on the new filesystem.
The s-bit (special file) is missing.
1) Is this something I can repair myself?
2) Do I even have to repair it, or can the file just be deleted?
3) Does the QM need to be restarted to force a reallocation of the file?

Did you clear shared memory before moving the qmgr? (amqiclen). This might have removed such as it pertains to memory. For the rest as a prudent move I would want to set back the "sticky" bit before starting the qmgr. The root user might be needed to change the permissions on the file.
Enjoy

Probably not, but I am not knowledgable of the procedure being used by operations group when they take down systems for migration; it predates my being here - something else to learn.

Okay, any idea how I would do that? remember, this is the left-most s-bit in the 'ls -l' indicating a 'special file', not the o/g/w s-bits; this bit can not be turned on, it is an indicator, not a permissions, bit.

Sure but it should still be some octal combination right? If not it might depend on the type of file. I would think that this might be no ordinary file but a pipe file or something like that....

Yes, that was why I posted the original message - it is a special file in the spipe dir, so what's the downside (if any) to its losing its special-bit, and what should I do about it?

Well at this point just restarting the qmgr would probably do.
