Hi Gaurav,
User is executing Z reports, and it generate many update tasks, there are about 4 update wp run more than 30 minutes, after I canceled them by manual then it recovered normal.
1. some VBAK and VBRK tables are locked in SM12 for the same transaction.
2.there is no any locks in DB01.
system always report the alert 'High update response time', we increased two dialog instances last month.
SAP recommand us to adjust some oracle parameters, but I want to get the root cause first, because it never happened before.
Thanks,
Michael
