DBMS_ALERT looks like a great choice for asynchronous data movement. We want to use it. Problem is DBMS_ALERT.SIGNAL is too slow. It takes about 4X the time for an SQL insert. We are AIX 4.3.3 Oracle 8.1.7.0. Does anybody else have this problem? Is that much overhead normal? I did open a tar with Oracle, no response yet.

I don't think so. The DBMS_ALERT.SIGNAL does not get sent until the commit, but the statement itself doesn't block. So I don't think I'm waiting.

My experience with DBMS_ALERT is even worse. After we've upgraded to Oracle 8.1.7 from Oracle 8.1.6 we are getting intermittent "End of file on communication channel" during DBMS_ALERT.WAITONE(ID). Up to now, we are still trying to determine what could have caused this error intermittently, especially after a long wait such as more than 2 hours. This problem does not exist in Oracle 8.1.6.
