Re: dsm.opt file being corrupted/blanked
Thanks for the information/confirmation. I sure hope IBM will recognize and fix this. Since we've only seen/know of 2-occurances, this is mostly an annoyance. Sounds like it is related to the problems we experienced when we tried to do replication with Oracle backups. We run multiple RMAN processes simultaneously and the replication statements kept breaking them so we stopped replicating Oracle nodes. Zoltan Forray Spectrum Protect (p.k.a.

Re: dsm.opt file being corrupted/blanked
FYI. I have seen this problem on numerous occasions and with various client versions (Version 7, Release 1, Level 2.2 -> Version 8, Release 1, Level 2.0). Our analysis is that it is indeed related to replication (we have two servers that cross-replicate to each other). And to the fact that we often perform multiple backup sessions in parallel (SQL agent jobs that kick off dsmc.exe per database; we don't use TDP). It seems that each session wants to write replication failover values to the options file. And when multiple sessions try to do that in parallel, they collide with each other and end up completely wrecking the options file. Workaround we have implemented: allow TSM to write failover values to the options file just once and then mark it readonly. Subsequent sessions can't write to it anymore and hence can't destroy the options file. Only drawback: each TSM session now causes the following alert to be written to dsmerror.log: ANS4058I A write failure occurred while attempting to save node replication failover values to the options file. We know what causes these alerts and choose to ignore them. The backups themselves are not affected.

We did not test replication with this round of clients. I agree only replication would need to touch the OPT files.

Re: dsm.opt file being corrupted/blanked
We ran extensive testing on the 7.1.0 code and never saw this issue. Not saying the 0 base is not your issue but just haven't seen it. We have 7.1.6 out in the wild now and also have not seen this issue.
