Hi ,

The compression advisor job is taking more time for creating temp tables to calculate compression ratio and job got stopped since it's crossing window time. The job created temp table of DBMS_TABCOMP_TEMP_UNCMP 11GB and stopped during creation of DBMS_TABCOMP_TEMP_CMP.  The temp table DBMS_TABCOMP_TEMP_UNCMP  not dropped automatically but the job is stopped. The compression job is creating huge redo and filling the table spaces.

Compression type : OLTP

Kindly advise on this issue.

Thanks,

Sasikumar
