DBBACKUP using only one thread

[illllm]

Name Line Number Command
DBBACKUP 10 backup db devc=DBBACK_FILEDEV type=full numstreams=12 wait=yes
20 if(error) goto done
30 backup volhist
40 backup devconf
50 delete volhist todate=today-30 type=all
60 delete volhist todate=today-6 type=dbb
70 prepare source=dbb planp=/var/log/SpectrumProtect/RPF/
80 done:exit

this is my script.....

it used to work before, but now DBBACKUP is using only one thread. We ran the backup manually. Any ideas or suggestions as to why this could be happening ?

Many thanks!

I have seen this before and it was due to an error followed by a retry during the backup. The retry only uses 1 stream.

Thanks Marclant, yes that seems to be the issue. The DB backup starts with 8 sessions, then fails and then single session starts. I am trying to cancel the session/process but it keeps opening a new session.

ok it turns out that the archive log space must have 20% free. This is why the backups were failing .

well now there is 55% free and its still failing
