OMW applications begin to run too slowly

[ftufekcioglu]

We used DB2 for EnterpriseOne 8.10 before, than we changed the database to Oracle. After that OMW applications begin to run too slowly, especially checkout operations. Some checkout operations finish in a long time, but some others give errors like below :

"2552/2060 Wed Jan 18 17:41:08.345 JDETAMP.C6042
DeleteByOffset(): Can't locate key {"P55PR001" } in index 3

2552/2060 Wed Jan 18 17:41:08.408 jdb_ctl.c4929
JDB4200003 - OPEN TABLE NOT CLOSED = F98752

2552/2060 Wed Jan 18 17:41:08.423 jdb_ctl.c4929
JDB4200003 - OPEN TABLE NOT CLOSED = F98753

2552/2060 Wed Jan 18 17:41:08.423 jdb_ctl.c4929
JDB4200003 - OPEN TABLE NOT CLOSED = F98750

2552/2060 Wed Jan 18 17:41:08.439 jdb_ctl.c4929
JDB4200003 - OPEN TABLE NOT CLOSED = F98751

2552/2060 Wed Jan 18 17:41:08.439 jdb_ctl.c4929
JDB4200003 - OPEN TABLE NOT CLOSED = F98740"

What may be the reason of this problem?
