Message-ID: MIME-Version: 1.0 Content-Type: text/plain look at dlm configuration at the os level...pings? up/down converts normal? apply all patches. also look at UDP buffer size settings in the kernel. Oracle DLM use udp vice tcp and bad buffer sizes cause hangs. hth Ross Mohan -----Original Message----- Sent: Friday, November 30, 2001 12:12 PM To: Multiple recipients of list ORACLE-L Hi. I'm running oracle 8172 on AIX SP 4.3.3 in ops mode on 4 nodes. I have noticed that the queries that are trying to read the GV$ tables are hanging, while those using the V$ tables don't. I have looked at the locks/waits on each node, but didn't see anything unusual (or may be I missed). What/where should I be looking to figure out what is going on?
