How to Speed Up Database Upgrade when a New Index is Being Applied? (Doc ID 2425100.1)

Last updated on AUGUST 03, 2018

Applies to:

Oracle Utilities Meter Data Management - Version 2.1.0.3 and later
Information in this document applies to any platform.

Goal


During the database portion of a MDM upgrade, some parts are taking longer than expected.

As per the logs it shows that a particular index creation is taking a long time to complete.

Log might show it is occurring on a different index but the statement will look something like this:
CREATE UNIQUE INDEX D1T304P0 ON D1_INIT_MSRMT_DATA(INIT_MSRMT_DATA_ID) NOPARALLEL;

Because it takes time to execute, customers may question whether the changes are necessary. Often they would like to leave existing index in place or somehow make it faster to apply the index. How do they do this?
