In Our production in peak hours we have faced this problem.

initially we have noticed this by system lock error.we tried to kill dialog work process in with help DPMON and OS level also but it did' resolve our problem.after some time we have re-started the SAP and Database.now it is workig fine.

we have idenified in the dumps following errors:

1.Database inconsistency: Start Transaction SICK.

2.Exception condition "CONNECT_TO_ENQ_SERVER_FAILED" raised.

3. they are many dumps in system with the message "Database inconsistency"

our enque/tablesize: 20480

OS:Solaris

DB:Oracle 10g

SAP:Upgraded to ECC 6.0 from 4.6b 4 months back

can some one tell us why it happened for error analysys purpose.

Thanks in advance.

From experience I would say a good place to look for errors (and post errors) will be the database error log. Looks like the database engine is experiencing issues during peak loads. This will cause process errors on the central instance which would result in the central instance not being able to process enqueues.

Are you using replicated enqueue? Are you running a SCS outside of central instance?
