BOE XI3.1 SP3 ON SOLARIS Cluster/Fail Over ASSISTANCE

Former Member

H veryone; I have been looking for information on clustering and cannot find a definitive instruction set / workflow and I hope someone will provide enough pieces to put this together..

My situation:

1) Server A: Full deployment with Tomcat to Oracle

2) Server B: Also a full deployment with Tomcat to the common Oracle repository

Objectives:

- Users will connect to Server A

- If server A is down then they will connect to Server B

Questions ?

- What are the steps to install BOE on Server B (admin docs do have some info, but no explanation on how the IFRS/OFRS works?)

- Do I have to Cluster Tomcat? if so is there any preferred setup?

- Is there an explanation on how the fail over takes place? Is it manual? What happens after the fail over - is there any manual clean up processes that have to take place?

Check the Administrator's guide Section "Clustering Central Management Servers"

http://help.sap.com/businessobject/product_guides/boexir31SP3/en/xi31_sp3_bip_admin_en.pdf

Make sure to set up the file repository servers on both nodes to share the same directory

- Do I have to Cluster Tomcat? if so is there any preferred setup?

Fail-over at web server level is not in the BO scope and there is no official recommendation on how to do this. One option is to setup a web balancer device that will make both tomcat installations available to your user under a single hostname.

- Is there an explanation on how the fail over takes place? Is it manual? What happens after the fail over - is there any manual clean up processes that have to take place?

Failover is transparent to the end user. Keep in mind that failover works for the user session. The current action may fail (eg. running a report) but the session remains intact and subsequent actions are served by the working node.

Is their any theory of primary server and secondary server in boe?

I read the doc still i have these q?

for example:

10 users are accessing server A these 10 users unfortunatly server A is down, by theory it will move to server B .

for server B will it have its own FRS or will it take from the server A FRS or do we need any changes on FRS servers on server B pointed to server A.

will we have 2 separate nodes? i mean 1 for each server

The file repository servers (Input and Output) should be running on BOTH node A and Node B. This means that you will have 2 instances of the input file repository server and 2 instances of the output file repository server.

All instances of the Input FRS should point to the same directory. The same is true for the Output FRS instances.

I recommend to host the common file repository directory outside the BO servers if you want to have a real fault-tolerant setup. Failover capabilities for the file system hosting the file repository are outside the BO scope. AN option is to use a SAN system for this.

II hope this answers your question.

All instances of the Input FRS should point to the same directory. The same is true for the Output FRS instances ? in order to do this do we need to do any configuration on the servers.

If we move the data(i mean users and reports) from QA to UAT server A, will have the same data(i mean users and reports) in UAT server B?.

Hi ,

FRS:

FRS File system needs to be one for both BOE CMS servers you are going to configure for clustering.

So what we do here is we take NAS mount points of FRS in both BOE server

IN Server A:

c.sdn.net/FRS ( FRS File systme)

IN server B:

c.sdn.net/FRS (FRS File system)

Both of them are same referring to the actual file system located in c.sd.net machine.

I guess now we are clear about FRS file system. wherever you updated the data it will be updated under the same file system.

Coming to the configuration :

You need to configure the File systme path in FRS servers under Central Management Console.

Nagraj Kundan.
