PI Installation

[Former Member]

Hi All,

Below is our Landscape.

Hardware

Server u2013 4 x 4 cores

RAM u2013 16 GB

HDD u2013 6TB

OS u2013 Win 2K8 R2

DB u2013 SQL Server 2K8 R2

System Landscape

SAP SRM 7.0

SAP ECC IDES 6.04

SAP MDM 7.1

SAP CE 7.2

SAP NW EP 7.01

Now I am Planning to install SAP PI7.1 EHP1. Is it possible to install PI on the above landscape and what are the steps i have consider before going ahaed with installation.

I would go for a different machine.

I would also do a sizing before to make sure the system performs well.

HI Markus,

I am a part of a team called Center of Excellence here in India. We take care of all R&D/POC servers. We in fact have all our boxes filled with multiple SAP systems. So:

• Number one it is possible, provided you do perfect distribution of your data files across the file system.

• You have to consider the growth of the database and hence equally divide the disks in mannered logical partitions.

• More than the performance you should be worried about space, because that the biggest challenge.

• Archive logs have to be off, in case there not much of 'Very Critical" thing

• Ample SWAP space has to be Provided, that too demands huge disk spaces.

The advantage we have that we have SAN space available which can be utilized at dire times.

Majorly I think it should work If you have around a TB of disk space, you might be also required to allocate as much as 70 GB as swap space.

The only worrying thing is MDM. MDM Oracle eats up to GBs of CPU utilization. We had to hence migrate all of our MDM servers to SQL and move it out of our supervision and hand them over to MDM consultants. This specifically happens after an Upgrade.

Talking of upgrades, insufficient space would also not allow support pack upgrades particularly stack upgrades and EHP4, if you have some distance planning for any.

I would give it a thumbs up minus the MDM server (if you want MDM, try keeping it at SP2 or 3 only) and minus and major support STACK upgrades.

Hi All,

I stopped all the instance on the host, started the installation of PI7.1 EHP1.

Installation stopped at Create Java users. In this step, it was running for 1 hours.

Can you please help.

Check the logs, without logs impossible to say anything.

I never said it's not possible. It's just a pain to maintain and configure. The problem is not the disk space - this can be managed nicely - but the memory. If you mix MDM, ABAP + Java you may the issue, that in a performance critical situation you will not be able to react quickly without impacting other systems. We had this configuration earlier (years ago) and we switched back to one server/VM --> once instance.

If you "just" use those systems to configure things and test things out it's a very good way. Since it was not said whether those are production instances (where 'production' means users doing business work - not testing) I was just assuming as such.

I can just think about that if e. g. PI has a memory problem - instance can't be started because a shared memory segment can't be created because of too less swap. In that case ALL instances + all database are affected if the system needs to be restarted, not to speak of monthly Microsoft patch days - or firewall configurations if you don't patch with all the ports.

As said, it can be a GoodThing(TM) to "just set up and to a POC" but I would very much refrain from such configurations if some hundred users are to be working on that. In that case I'd say it's much easier to set up Hyper-V and install separate instances.

Hi Markus/Varun,

I need to make PI installation to use only certain amount of RAM and Processor during installtion.

Just say I have to define 8 GB RAM & 2*4 Core Processors during PI installtion or for any other installation

Is there any settings/parameters I can define to use the above resources.

Hi,

Allocating cores cannot be done, all you can do is you can increase/decrease the number of threads/processes that run during the Abap Import phase.

I believe you can allocate the desired RAM for SAP when you perform a custom based installation, This option was there on older sapinst, not sure whether this feature is still present.

Hi All,

I stopped the installation, uninstalled and restarted the installation from scratch, again got stuck in Install Java Engine phase.

When I checkd the sapinst log, I see the below error.

Please refer installation guide, [www.service.sap.com/instguides]

I could see that you already have 6 sap applications running on the same server, so I would suggest you not to overload it by installing PI on the same machine. 16GB is not sufficient to run all these applications. PI alone would need min 6GB.

Ensure that you have sufficient swap space.

Hi SBK,

Sorry, its 64 GB.

RAM u2013 64 GB
