Index Creation and precautions

in Database Administration (MOSC) 11 commentsAnswered ✓

Dear Experts,

APPL Team wants to create an index against one big table on specific column.

It is necessary but it was not tested in lower environment.

Index creation may take 5 to 7 hrs ( Segment size is 520+ GB)

If so , what are the necessary actions needs to be done to avoid database performance issue.

Is it necessary to predict index size of the column before we step into the process

Regards,
