Can someone please confirm the following advise from Index advisor is
normal for iseries and not a problem specific to our system? I am
finding it difficult to believe that system tables do not have proper
indexes (Index Advisor point of view).
I found couple of suggestions by Index Advisor on queries using views
(QSYS2.SYSTABLES, SYSIBM.SYSCOLUMNS, etc.. ) related to system
cross-reference files on our test LPAR. This LPAR was recently
upgraded to V7R1 from V5R4 by IBM team. There is no business
application activity on this LPAR at present.
One of the queries with index advised is "SELECT SYSTEM_TABLE_NAME
FROM QSYS2.SYSTABLES WHERE TABLE_SCHEMA = ? AND TABLE_NAME = ? FOR
FETCH ONLY WITH NC". The query is executed by QDIRSRV. Index advised
is on QADBXREF (columns DBXREL , DBXLB2 , DBXLFI, DBXATR).
Thanks..
Satya..
