RMAN-06025: no backup of log thread 1 seq 43 scn 3924903 found to restore ...........

quit
I can resetlogs and that error disapeire
Does anybody know that wrong with that script?

Really the error is very strange realizing that if functions well for about 6 days or something like that.
this is a notable line in the error.
some targets not found - aborting restore
I recommend you to check very well your targets path
to be restore. I think that is the cause of the failure.
