wouldn't there be a chance that there might be race condition issues?
Suppose that two processes can modify the file at the same time and that
could corrupt the countfile.
Before testing NBU6 in the future we will just use the old flat file backup
(cron jobs dump the db to flat files).

Subject: RE: [Veritas-bu] Multiple data stream and bpend_notify script
In unix, I do this with what I call a "count" file.
As each stream ends, it writes appends a line to a common file. The script
then checks the number of lines in the file and compares it against the
"STREAM_COUNT" variable. If they match then the end-job is run & the count
file removed.
Beats me how to do this in MS Batch files but here's my script's logic:
echo $STREAM_NUMBER >> /tmp/countfile
if [ `wc -l /tmp/countfile | awk '{print $1}'` -eq $STREAM_COUNT ]
then
echo "Last stream"
rm /tmp/countfile
<run end-of-job-stuff>
fi
There's some additional logic in the bpstart_notify script to check for an
old countfile that's gotten "lost" because a previous stream ended without
running it bpend_notify script. This, of course, may lead to the end-of-job
startup stuff not running. Usually, for me, that's not an issue.

Subject: [Veritas-bu] Multiple data stream and bpend_notify script
Hi gurus,
We have a file system backup. It is being backuped as multiple data
stream.
We are backing up offline sql backup. So, in the bpend_notify script,
There is start command to start sql after finishing backup.
As there are multiple data stream, after completion of each data stream,
Nb run bpend_notify script. We have to instruct the script,
There are multiple data stream. In fact, in the admin guide,
We have found some variables to support multiple data stream:
STREAM_NUMBER
STREAM_COUNT
However, I do not know how can I use these variables in my bpend_notify
script.
Does "Set STREAM_NUMBER=1" work? I am not sure. How can I tell the
script,
This backup is being backed up via multiple data stream. Please wait?
Is there any idea about that? I would appreciate if you could help me.
Regards,
Asiye
