Tablespace Point in Time Recovery fails with RMAN-06026:

Question

I have cataloged with RMAN the datafiles from Snapshot backup. Still it fails with the following error.
RMAN> RECOVER TABLESPACE TSPC UNTIL TIME "to_date('03-apr-2013 02:18:00','dd-mon-yyyy hh24:mi:ss')" AUXILIARY DESTINATION '/tmp/auxpran';

Answer 1

I had created a snapshot of the database(datafiles and archivelogs) and cataloged them.
CATALOG START WITH "+TBL_DG_DATA/ORCL/DATAFILE/" NOPROMPT;
catalog start with "+DG_ARCH/ORCL/ARCHIVELOG/" NOPROMPT;
The time i gave was after the snapshot was created.
When it failed the first time I created another controlfile using
sql "alter database backup controlfile to ''/tmp/auxpran/controlbc.ctl''";
And ran the recover command after the time after i generated this controlfile. Changed nothing else. TSPITR completed successfully. But it had failed first time. Cannot figure how it ran the second time but failed the first time.
