OS,DB Upgrade

[Former Member]

Hello Team,

We are using PLM system installed on Netweaver 2004 Server,Oracle

Version is 9.2.0.6.0 and OS is 32-bit Red Hat Linux version 3ES,Machine

type i686.

Now we are planning to Upgrade OS and Database on Server but we have

below doubts about the Upgradtion:

1) Presently 64-bit server is running on 32-bit Red Hat Linux version

3ES (Means we have 64 bit hardware and 32 bit OS is running on it). So

our plan is to Upgrade the OS to a 64 bit version.

Now our query is to which 64 bit Linux version we should go for

Netweaver 2004.

2 ) As I mentioned we are using Oracle 9.2.0.6.0 So our plan is also to

Upgrade Oracle to 10g or 11 version but we are not sure with which

release we should go.

So please confirm for Netweaver 2004, and Upgraded OS verion( Target

version of OS) which Oracle version , We should go for smooth

Functioning of Application after the system Upgrade.

Components Installed on Server are as:

SAP_ABA 640 0010 SAPKA64010

SAP_BASIS 640 0010 SAPKB64010

PI_BASIS 2004_1_640 0007 SAPKIPYI67

ST-PI 2008_1_640 0003 SAPKITLRC3

SAP_BW 350 0010 SAPKW35010

CPROJECTS 310_640 0009 SAPK-31409INCPROJECT

ST-A/PI 01M_BCO640 0001 SAPKITAB6F

Kernel Information :

Kernel release 640

Compilation Linux GNU SLES-7

Patch Level 247

ABAP Load 1521

CUA load 17

Mode opt

Please help us in confirm this information.

Thanks & Regards,

I would:

- do the upgrade to Oracle 10g (or 11g) on 32bit

- take a full backup

- delete the system and install a recent RedHat version (Redhat 5.6 or Redhat 6)

- do a system copy with the backup using 64bit

I would vote against going to RHEL6 at this time.

1.) It's not supported by Oracle. I doubt you'll see Oracle support it until OEL6, which will likely come after CentOS6. Both are being delayed because the new method RHEL is using to deploy their kernel in RHEL6.

2.) It's not supported by SAP. I doubt you'll see SAP support it until Oracle supports it. Which, if you read #1, you'll notice it may be a little while.

The current plan is to have RHEL6 fully validated for SAP by end of Q2 2011. If you like you are able to start the upgrade project already. If you have doubts, please open an OSS call on BC-OP-LNX-RH and we can give you a preliminary OK for your projects.

Thanks,

AFAIK, SAP no longer support 32-bit installation.

Should this kind of customer upgrade directly to 64-bit? is that possible (using SAPup)?

Or, upgrade to next version 32-bit, then convert to 64-bit?

Thanks before.

This is not a SAP upgrade so sapup would not be involved.This would be a system copy.I think red hat 5 was recently certified.OS and DB combinations would depend on the PAM.Not sure about whether it would be heterogenous or homogenous.Usually 32 bit to 64 bit are homogenous if the underlying architecture remains same.

Hello Shivam,

Always when you have doubts about any product if it is supported or not, and if it is feasbile to upgrade, you should look on the Product Availability Matrix, that you can access by service.sap.com/pam. You can see there which operating system at which version you can install along with the database vendors and releases too. All you have to do is select the product which you are going to upgrade.

Hi Mauricio,

Thanks for reply.

I am working on PAM also but I have doubt

1 - As communicated by my OS team we are using Red Hat Linux version 3ES but I checked on PAM

there is no such version available there available versions are :

LINUX REDHAT EL5

LINUX REDHAT EL5

LINUX SUSE SLES10..

LINUX SUSE SLES10...

LINUX SUSE SLES8.

LINUX SUSE SLES9.

LINUX SUSE SLES9.

So I am thinking 3ES or 3 EL is same or they are using Linux SUSE not Linux Redhat.

Please sugget if you have idea of it.
