Hi, Creating new index to COMPLAINT_WORK (Copy of PC_WORK)


Hi Team,

My DB team suggested to create below index on PC-WORK table,

create index complaints_work_idx on complaints_work (caseownerid, pystatuswork, pxobjclass)

Could yo uplease suggest what is the impact on creating new index on PEGA table.

Queries:

1. Required to take a back up before creating index?

2. Is there any PRE or POST activities required to do while creating index (or just running above script in DB is enough)?

FYI,

PEGA Version: 5.5

REcords in Complaints_Work - 3443275

Thanks & REgards,

Gopi

1. no

2. not much I can think of except carefully monitor your system performance especially queries against this table. Your DBA suggests index for a reason, presumably speed up data lookup, but in general it could hinder insertion/updates.

FYI, your version is really old, consider upgrade to pega 7 in the future. I did not find any index for pc_work in the latest release of pega 7.2.
