ORA-19755 error using block change tracking file.

  • Posted by Arjun Raja

While restoring and recovering a database UNTIL TIME which uses the block change tracking file, the recovery may be interrupted.

This was the error –

released channel: ch1
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================

ORA-27037: unable to obtain file status

IBM AIX RISC System/6000 Error: 2: No such file or directory
Additional information: 3

This file is not backed up by RMAN and not needed for recovery – it is purely used by RMAN for speeding up the incremental backups.

Therefore to workaround this problem simply disable block_change_tracking and restart the recovery .

sql > alter database disable block change tracking ;


RMAN> run {
SET UNTIL TIME “TO_DATE (’09-02-09 18:00:00′, ‘DD-MM-YY HH24:MI:SS’)”;
allocate channel ch1 type ‘sbt_tape’ parms ‘ENV=(TDPO_OPTFILE=/usr/tivoli/tsm/client/oracle/bin64/tdpo.opt)’;
recover database;
release channel ch1 ;

HI my question is: Can I migrate a IBM DB2 (5.4 version) to Oracle 11g? Is Oracle SQL Developer the correct tool? I already read your article about the migration with Oracle SQL Developer, but I read that Oracle SQL Developer support DB2 6, 7, 8 and 9. But Don`t said in any place that I can use that tool with that version (5.4). Please Can youn help me
