Hi all I'm doing some maintenance - which is done quite often, never had this problem before - which requires me to disable triggers, run some updates and then re-enable the triggers. Where the whole process normally take 30 sec , it took much longer today and I cancelled after 5 minutes. After running the statements individually to pinpoint the issue , I identified that the problem is on the first line. >> ALTER TABLE tab DISABLE TRIGGER trig; I have not been able to run this successfully -- after 10 minutes the connection ( to remote DB ) got severed . Any ideas on where I can start to look for the cause of the problem ?
