Databsae Issues

Hi, We have an online environment at 1 of our client. We have 2 machine working parallel in a replicated environment. Leme tell u a bit about the machines configuration. Basically their are 3 Pentium Pro Processors in each machine. What happened wrong is, that our primary machine motherboard and 1 of the processor goes down, I make my secondary machine as an standalone server. When this hardware problem is fixed, I again have to bring up the replication. Leme mention here, that now in my primary machine there is only 2 processors while in my secondary machine I have 3 processors. The replication is successfully up and the servers are talking to each other well. Now the problem that comes next is My primary server all of a sudden stops. I mean the machine doesnt get hangs neither the Database engine but whenever user/me trys to connect 2 a any database with DBACCESS command it stops and give errors like : 25588: The appl Process cannot connect to online server online2. InterruptedSystem Call. and further when i try 2 access the database engine using the ONMONITOR command the first error it give is : WARNING: Network Down. While i can easily c that the database engine is up and working fine, I check that onstat -d command. God I dono whats going on their, I even doesnt give ne error in the online.log files. Yes another point that comes 2 my mind is, the logical logs. I even tried that, by trying 2 backup the logical logs i use ontape -l command 2 do that, but it again give error like : Server is in incompatable state. Yes, I did found the resolution 2 this problem, which is by shutting down the databsae engine and again bringing it up. But, this is not the resolution. Please any type of help in this regard is appricated. Thanks Moazzam
