Home -> Community -> Mailing Lists -> Oracle-L -> Re: FILE IDENTIFY wait event
If a wait-event (i.e. FILE IDENTIFY) was posted, then Oracle was undoubtedly making a system call such as "open()" or "fstat()" or something. If those system calls "hang" when the device file exists but the underlying device is offline, then there is nothing Oracle can do about it...
It could be platform-specific behavior; it might "hang" on one platform and fail on another...
The volume was offline. Once it was back online, Oracle resumed the process of creating a tablespace.
Which brings up another question...why did Oracle wait on this condition instead of terminating with an error? If a file-system directory/drive cannot be found, the attempt to create a tablespace will fail. Is there something different in using a raw device?

Make sure that the volume group underlying the logical volume is ONLINE?
To test, I like to do something quick like "dd if=<raw-device> of=/dev/null count=100" to test the readability of the raw device. If this fails, you can go to the SysAdmin with something that is pure UNIX...
Oracle8.1.7 on Solaris8
I am trying to create a tablespace on a raw device and the SQL*Plus session that performs the tablespace creation is waiting on a 'file identify'. A quick search on metalink and other docs did not indicate the root cause of the wait event.
I have used the raw device previously and the create tablespace uses the 'REUSE' option.
Okay gurus...any clues as to exactly what conditions cause the event?
