2 SCM 4.0 Optimizer instances for one SCM system as high availability?

Hi

Can we install more (i.e. 2) seperate SCM 4.0 Optimizers and connect them both to one SCM Server system?

If yes:

1) Can/will the SCM Server system used both optimizers?

2) If one failes, can/will the SCM server then just use the one still running

Best regards

Tom

Hi Larsen

Since optimizer is just exe.file, you can install several optimizers<engine> (put exe.file into

different location <folder>) and it should not be in same HW. And in the IMG customize you can priolatize Optimizer engine. So system can use several engine depending on the priority (or for some component like CTM, you can specify engine and run CTM in parallel with using different CTM engine for different objects.

And I know 1 company who install 2 CTM engine into 2 servers for high availbility solution (This means active server A has 2 CTM engine/ stand by server B has 2 CTM engine).

To use fail over scenario with several server, I think you need to define following customize in SCM system.

T-CD /SAPAPO/COPT01 (Define directly and engine name)

T-CD /SAPAPO/COPT00 (Check availbility of Server)

<Also RFC definition should be correctly customized in SM59).

Hi Keiji

Thanks, just to understand/

Is it possible to have 2 SCM optimizers running on 2 separate servers AT THE SAME TIME supporting 1 SCM Server system for all objects/components, so that if one of the SCM Optimizers crashes, then the remaining Optimizer will support the APO server for ALL calls to optimizer?

Best regards

Hi Tom

As Keiji says you can put them on separate servers at the same time. The configuration settings on your SCM system will need to be as follows:

/sapapop/copt01

Give each server the optimiser exe file is on a separate identifier e.g. SNP01 and SNP02 each pointing to the RFC destination of your optimiser servers.

/sapapo/copt00

Check the box "Check server Availability"

Once you have done the above then the optimiser will look for the first "available" server from the list given in /sapapo/copt01.

Hope this helps

Hi Tom

Yes it should be possible.

So 1 server become crash, application will take 2nd servers's optimizer.
