![]() ![]() Then, run the following SQL query to identify queries consuming high CPU: select stq.userid, stq.query, trim(stq.label) as label, stq.xid, stq.pid, svq.service_class, For example, make sure that all transactions starting with a BEGIN statement are accompanied by an END or COMMIT statement. To prevent these sessions from remaining open, be sure that all transactions are closed. Then, run PG_TERMINATE_BACKEND to stop any long-running transactions. To identify long-running sessions, use the following SQL query: select *,datediff(s,txn_start,getdate())/86400||' days '||datediff(s,txn_start,getdate())%86400/3600||' hrs '||datediff(s,txn_start,getdate())%3600/60||' mins '||datediff(s,txn_start,getdate())%60||' secs' as "duration"įrom svv_transactions where lockable_object_type='transactionid' and pidpg_backend_pid() order by 3 While the queries are running, retrieve locking information. Idle sessions can cause additional lock contention issues. This can be a result of idle sessions present in the cluster.
