Learn more!It seems that lately, I have been getting around ORA-00600 errors when duplicating databases, and this will be a very short blog post on how I worked around ORA-00600 [KCBTSE_ENCDEC_TBSBLK_1] when duplicating a PDB and TDE is enabled in the Source PDB in a 19.10 version.
Over the last months, the team had been seeing this ORA-00600 intermittently when issuing the duplicate command below:
RMAN> CONNECT AUXILIARY * 2> CONNECT CATALOG * RMAN> run { allocate auxiliary channel ch1 type 'sbt_tape' PARMS="SBT_LIBRARY=/u01/app/CV/commvault/Base/libobk.so, BLKSIZE=1048576 ENV=(CV_mmsApiVsn=2,CV_channelPar=ch1)" TRACE 0; allocate auxiliary channel ch2 type 'sbt_tape' PARMS="SBT_LIBRARY=/u01/app/CV/commvault/Base/libobk.so, BLKSIZE=1048576 ENV=(CV_mmsApiVsn=2,CV_channelPar=ch2)" TRACE 0; DUPLICATE DATABASE CDBPROD TO CDBSTAGE PLUGGABLE DATABASE 'PDBRENE' ; }
When I finally got involved and the problem was explained, I started to see a trend: whenever the duplicate command used an L0 + L1 backup for the restore, we were hitting the ORA-00600. Searching MOS, there are several bugs out there, but most are on the backup side of things, not on the restore side of it, so I couldn’t get an exact match.
Looking at the log and trace, you could see this happening on the incremental restore part of it.

The workaround I applied to this bug is to use only the L0 backup for the duplicate command. Once I used that, the command will succeed.
channel ORA_AUX_DISK_1: restoring archived log archived log thread=1 sequence=16 channel ORA_AUX_DISK_1: restore complete, elapsed time: 00:00:02 Finished restore at 25-JUL-21 Performing import of metadata... Finished Duplicate PDB at 25-JUL-21
We are currently working with Oracle on identifying the bug, but for now, using only the L0 backup is how we are working around it.
