RMAN - A "delete archivelog.." incorrectly got rid of an archivelog?!

[Axr2]

target - 9.2.0.4
target OS - SunOS 5.8

catalog - 9.2.0.5
catalog OS - AIX 5.1

FYI -
I'm guessing the issue had something to do with the "timing" or scheduling of the 2 scripts. For now, as a work around - I've incorporated both "backup archivlog" and "delete archivelog all backed up 2 times" into a SINGLE rman script (instead of splitting them into 2 separate jobs). That'll hopefully prevent it from occuring on production atleast.

I've left things 'as is' (with rman debug) on DEV to simulate the failure again.

Btw, the debug feature is quite enlightening..for those that haven't tried it - give it a shot, and look at the tracefile generated. It makes interesting reading. You get to see the different rman procedures being called, along with the bind variables. I hadn't seen this before. It seems neat.

Adding a debug is typically done like this -

rman trace=file_name
connect target /
connect catalog .....
run
{
debug on;
allocate channel c1 type ...... debug=5

debug off;
}
