Applies to:Oracle Server - Enterprise Edition - Version 184.108.40.206 and later
Customer gets ORA-01013: user requested cancel of current operation in alert.log,
and ORA-7445 [tbsafl] in trace file when adding a datafile.
This issue may happen with creation of a compressed tablespace, or addition of a datafile to
a compressed tablespace, after installation of 112031DBPSU and 11203BP2 which came out in
You need to check the date the tablespace was created:
SQL> select a.CREATION_TIME from v$datafile a,v$tablespace b
and b.name ='TSNAME';
If it was created after installation of those patches, it could be that the tablespace was
initially created without compression, and compressed after its creation. In this case,
adding a datafile will still fail.
