RE: Apache and Orion
I am running an orion cluster behind a load balancer and Apache at the front end on same machine, its on a test system so theirs no real load. We are using Oracles 9i Application Server. We use Apache for oracle reports and SSL and of course serving up static content etc. The problem is with mod_proxy which is just plain slow. Oracle is coming out with a ojp protocol which is based on ajp13 which will solve my problems, but until then (late october) I wanted to use Orion but it just doesn't integrate well with apache. Any suggestions ? No i haven't tried the tunnelServlet, I will look into that. I was just wondering if anyone else has this kind of setup. Note we are using Oracle's OC4J (which is essentially orion). They bought Orion and popped it into their next release of application server.

Its a little "bass-ackwards", but orion could be faster than apache in this respect. Also, are you running orion, the loadbalancer, and apache on the same machine? This could be just a load issue. Lastly, orion is generally faster than apache at serving up static content. There are very good reasons for using apache for static content, though, that have nothing to do with speed. (For example, you have one ssl cert for apache, and you don't want to pay for another one for orion.). regards, the elephantwalker -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Gurinder Randhawa Sent: Tuesday, July 10, 2001 7:36 PM To: Orion-Interest Subject: Apache and Orion Is anyone using Apache as a front end to Orion.

Re: Cluster configuration
In regards to my last email i have changed RMI and JMS ports fine and i got rid of Address already in use message upon Orion instance startup. However i still cannot shutdown the processes properly. I have also noticed multiple Loadbalancer processes running, I don't know how though ? Any ideas or suggestions on starting and shutting down orion instances and loadbalancer on same physical host ?

Re: Cluster configuration
I have managed to setup a cluster-island with a loadbalancer. I have a web-app that is shared. I am running Apache in front of Orion. I can start everything fine except for 2nd instance of orion in cluster i get the error: Error starting JMS-Server: Unable to bind socket: Address already in use Error starting RMI-Server: IO Error: Address already in use Warning: Error reading transaction-log file (/oracle/app/oracle/product/oas9i/Apache/j2ee_2/home/persistence/transactio n.state) for recovery: premature end of file Where can i change the ports for these or how would i resolve this ? Also i have apache running on port 80 and i would like to run loadbalancer on another port. Would i specify this port in the loadbalancer.xml file or at startup command line for loadbalancer ? Is it recommended to run loadbalancer on port 80 ?

Re: Cluster configuration
Another question in regards to Apache running in front of the load balancer. How does apache send requests via mod_proxy (ProxyPass...) to loadbalancer ? Is there any xtra config required or do you just specify loadbalancer port in httpd.conf file ?

That is, if every server was sharing its http sessions with every other server, you can see how the power of e and factorial are related. (sigma (1/n!)) == e. So instead of the traffic being proporational e^s, where s is the number of sessions, the traffic is proportional to s*n!, where n is the number of servers in a cluster. If a cluster has three servers, this seems to be a good comprimise between redundancy and multi-cast traffic. The loadbalancing bit randomly picks servers ... not clusters. So if one server goes down or is removed, another server in its same cluster takes over. This is the fail-over policy. regards, the elephantwalker -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Gurinder Randhawa Sent: Friday, July 06, 2001 5:14 PM To: Orion-Interest Subject: Re: Cluster configuration Thanks for the response Jeff, what i wanted was first and foremost was if one orion instance fails another one to kick in with session replication.

Re: Cluster configuration
One other question i had was...when you setup a "cluster-island" do you install 2 seperate orion instances with same cluster id in web-site.xml ? We are setting up 2 cluster-islands witha load balancer running behind apache on same host (one physical sun box) for one web-application. So to add to my question above for 2 cluster-islands do we need to run 4 instances of orion or just 2 ? The documentation wasn't clear to me on this I have it working for a single instance of orion but need to do clustering for scalability and fault tolerance issues. How does this perform ?
