Informix HDR problem

Hi, Im trying to setup replication between two servers absolutely identical in setup. Theyre both running SCO OSR5.0.5 and Informix 7.30 UC2. The problem is that when connecting to each other, the initial log exchange seems to hang... BUT this does not happen all the time, occasionally the connection succeeds but mostly fails. Originally I thought that this was a networking problem, but the network is 100% functional. Some info : /etc/hosts (identical to both machines) : 127.0.0.1 localhost 172.168.4.206 mediprod mediprod.meditrac.co.za 172.168.4.207 medirepl medirepl.meditrac.co.za excerpt from /etc/services (identical to both machines) : mtracptcp 1501/tcp Informix Online tcp service mtracrtcp 1502/tcp Informix Online tcp service $INFORMIXDIR/etc/sqlhosts (identical to both machines) : # Primary mediponl onipcshm mediprod mtractcp mediptcp ontlitcp mediprod mtracptcp# Secondary medironl onipcshm medirepl mtractcp medirtcp ontlitcp medirepl mtracrtcp DRAUTO is set to 0, If anyone requests I can send the rest of the onconfigs. (The dbspaces are identical though) After restoring the "ontape -s" from the primary with "ontape -p" on the secondary I issue: onmode -d primary medirtcp (on the primary) and onmode -d secondary mediptcp (on the secondary) The two servers connect and these are extracts from the online.logs : Primary : 09:39:20 DR: new type = primary, secondary server name = medirtcp 09:39:22 DR: Primary server connected 09:39:22 DR: Receive error 09:39:22 DR: Failure recovery error (2) 09:39:23 DR: Turned off on primary server 09:39:23 Checkpoint Completed: duration was 0 seconds. 09:39:23 DR: Cannot connect to secondary server 09:39:33 DR: Primary server connected 09:39:34 DR: Sending log 22 (current), size 250 pages, 5.20 percentused Secondary : 09:39:26 DR: new type = secondary, primary server name = mediptcp 09:39:26 Warning: Invalid dbspace 'dbtmp1' listed in DBSPACETEMP. 09:39:26 DR: Trying to connect to primary server ... 09:39:29 DR: Secondary server connected 09:39:30 DR: Failure recovery from disk in progress ... 09:39:32 Logical Recovery Started. 09:39:32 Start Logical Recovery - Start Log 22, End Log ? 09:39:32 Starting Log Position - 22 0x8018 This is where everything (mostly) stops. If it succeeds then the replication initiates otherwise it just hangs at this point. In the onstat - output I sometimes get BLOCKED:CKPT or CKPT REQD but this is not always the case... Whew, sorry for the long post :) If anyone can help me I would be EXTREMELY thankful ... Johan. Sent via Deja.com http://www.deja.com/ Share what you know. Learn what you don't.
