Hi guys
During Downtime Phase, step PARCONV_UPG is taking several hours to complete. On the first run lasted 23 hours until cancelled during a Tablespace issue; i have added more space and now its running again but taking several hours to complete
The only job running is RDDGENBB_0, while the others RDDGENBB_X, are already finished.
It seems to be converting table BSEG by droping and creating table QCMBSEG, but I,m still clueless if there is a way to speed up the process, parallelize it
Database is Oracle 11.2.0.3, and BSEG size is around 6TB, so bear in mind that table has a lot of records, but still this behaviour does not seems normal
On a Sandbox upgrade we did a few months ago on the same database, this step only took up 11 minutes.
Job output,
2 EGT054XRequest: Convert "Table BSEG (DDIC/02.02.15/11:05)"
3WEGT062 A restart log already exists for table "BSEG"
4 EGT092 Conversion of table "BSEG" was restarted

4 EGT841 Mapping function: "DEF_MAP"
4 EGT818 Commit after at least every "16.777.216" bytes
Any ideas on how to speed up this step?
I have read note 558197 - upgrade hangs in PARCONV_UPG, XPRAS_UPG, SHADOW_IMPORT_UPG2, but i understand this is for older relases of Oracle, and in SUM tool, this script is executed as part of Upgrade
Best
