Hi,
When you run the upgrade, if the property "rebuild.indexes" in setupDatabase.properties file is set as true, then the upgrade step calls the SPPR_REBUILD_INDEXES procedure to rebuild indices and forces the re-computation of table stats for the purpose of upgrade performance.
By default, this property is set as FALSE for all DB except DB2 Z/oS. I understand that this step is time consuming.
Won't setting up this property avoided your problem in the first place ?
Thanks, Jaffer
To resolve this issue , we need to follow below steps
Below is the sample sql statement
ALTER INDEX ALL ON rules.pr_index_reference
REORGANIZE ;
GO
UPDATE STATISTICS rules.pr_index_reference
GO
