unable to Find archivelog XXXX

Problem: Unable to find/lock the archivelog 'XXXX"

Scenario:
Archive log we manually backedup to tape and deleted from the source.

We configured a catalog for that database and then gave the below command;

rman target / catalog rmanrep/rmanrep@RMAN4
Recovery Manager: Release 9.2.0.3.0 - Production
Copyright (c) 1995, 2002, Oracle Corporation. All rights reserved.
connected to target database: RMAN4 (DBID=4109780682)connected to recovery catalog database
RMAN> backup format '/u01/app/oracle/sandy/proddb/1.arc' archivelog all

Unable to identift/locg logfile '/u01/app/oracle/sandy/proddb/9.2.0/arch/REOPENPROD_1_42.arc'


This error occured as 42 was deleted before creating the catalog.

the solution for this proble is

rman target / catalog rmanrep/rmanrep@RMAN4
Recovery Manager: Release 9.2.0.3.0 - ProductionCopyright (c) 1995, 2002, Oracle Corporation. All rights reserved.connected to target database: RMAN4 (DBID=4109780682)connected to recovery catalog database

RMAN> crosscheck archivelog all;

The above command "crosscheck archivelog all;" will actually delete the archivelog entry from controlfile. Thus Catalog will not try backingup the archivelog which is not present(or deleted)
