Unanswered: Critical IO problem with file LKDBNAME
I'm having a serious IO contention problem with the file $ORACLE_HOME/dbs/lkDBNAME.
I have an Oracle 9i R2 patch 220.127.116.11 on an AIX 5L and a Clariion CX400 EMC storage.
I have 12Gbytes of RAM em 6 CPU's.
Oracle SGA is about 8Gb.
so thats the problem:
all processes goes VERY slow and the iostat shows me 100% busy internal disks (not storage ones).
The UNIX guy said that the file been used is $ORACLE_HOME/dbs/lkDBNAME.
Anyone knows what and why Oracle is reading that file soo much ?
Thats been critical so that all system goes very, very slow.
I have been looking at metalink, and it was helpless.
Thanks a lot for your help.
