OS Migration from AIX to SUSE Linux

Hi All,
We are having a scenario in which we want to change our OS.
First we have AIX with oracle 10.2.0.4 and SAP ECC 6.00 which we want to change into new hardware with SUSE Linux with same Oracle and ECC 6.00
So we are planning to do Oracle Offline backup restore in the linux system, but in some placed i found If not homogeneous it will not work..
Please let us know the best way.
Thanks & Regards,
Balaji.S

Dear Balaji,
you also need a certified migration consultant, see [https://service.sap.com/osdbmigration|https://service.sap.com/osdbmigration]

Migrating from AIX to Windows

Hi all,
We are considering in a SAP R/3 4.6c to ECC6 Upgrade, the option to migrate from AIX to Windows OS.
We heard that this option is not so usual.
- Could you tell us some feedback and recommendation about it?
- What kind of issues will we face?
Thanks for your help,
Chris

Usual? What is "usual"?
> - Could you tell us some feedback and recommendation about it?
> - What kind of issues will we face?
This depends heavily (if not only) on your environment. Some thoughts:
- Windows is little endian whereas AIX is big endian; this may affect connected software (non-SAP software, filesystem transfers etc.)
- additional software plus licenses may become necessary (cluster, backup...)
- do you have enough knowledge about Windows (+ its internals) as you have on AIX? Windows is not "easier" by default just because you have a mouse to click... (even if everyone thinks it is). Windows administration is totally different to any *nix (you may need to change scripts, consider updating regularly, think about problems you didn't have before (Virus, Worms) etc.)
- Hardware for Windows is usually cheaper than Power based hardware for AIX
- Windows licenses (+ CALs) must be bought
Just as another thought: Did you consider running Linux instead? You will use the same (cheaper) hardware with a more common environment (if you come from AIX)?

Migration from HP-UX to Linux 64 bit on SAP XI 3.0 environment

Hi All,
Can you please provide the requirements steps/documents for migration from HP-UX to Linux 64 bit on SAP XI 3.0 environment
Thanks
Sateesh

Hi Sateesh,
This migration which you refer here is a heterogenous system copy. you may refer the system copy guide for the same.
you can get the system copy guide from the below link

Oracle E-business suite database migrate from AIX to Linux

Oracle 11i application database migration from single Aix instance to oracle Linux cluster RAC.
What is the easy way to migrate?
Migrate single instance from aix to linux cluster.
OR
Migrate single instance from aix to linux cluster RAC.
We have installed oracle Linux cluster.
Please help me which way I can go with RAC.
Thanks
Prince

Migrating to a single instance will be the simplest. The migration itself will not be much different between the two because you're migrating from one platform to another. The options you have available are, the traditional IMP/EXP, datapump, and RMAN to migrate to either a standalone or RAC environment. The difficulty will be in creating a RAC environment and a little a few extra steps in the RMAN restore. Working with RAC will make things harder, but the actual migration is similar. The steps to IMP/EXP, whether it's traditional or Datapump will be no different. However, standing up a RAC database will be.

Need advice migrating from AIX 7 filesystems to Exadata Linux ASM - Large DBMS

We are using 11.2.0.3 and 11.2.04 databases on AIX 7.1 using AIX filesystems . We have some 2TB databases and some much smaller. About 50 production and 200 non-production databases. We are migrating to Exadata 4 with Linux . What is your advice on the method of migrations that should be used. We may be able to take some outage time to do this.

I echo the data pump export/import recommendations. I've used data pump several times to migrate databases to Exadata - including an environment with a few DBs on AIX Power PC to Exadata last year. If you can take downtime, it is the simplest, most flexible and least risky method - and if you can put a little thought and extra effort into it can still be very performant. On Exadata it's good to setup the environment according to Oracle's published best practices - which usually means some configuration changes from your source. Data Pump allows you to set this up first and have it ready to go - then do the migration into a properly configured database. You can also put the source DB into read-only while the migration takes place if that helps the downtime requirements.
Some suggestions to maximize performance and limit downtime:
Consider using DBFS file system on the Exadata, and then mount it using NFS to your source DB servers, for the data pump file location. This may take a little longer on the export, but avoids having to do a separate copy of the files over the network afterward and can make up the time. Once on Exadata, importing off the local DBFS can really perform well.
Use parallelism with data pump to speed up the export and import. The degree will need to be determined based on your CPU capacity, but parallelism will speed up the migration dramatically.
If you're licensed for compression - use the compression with Data pump to minimize the file size.
Precreate all your tablespaces first, and possibly even the schemas - this goes back to setting things up according to Exadata best practices. You can potentially use HCC and other things on the Exadata tablespaces if you so choose. You can always use the data pump mapping if you want to change a few things about the tablespace names and such from the source.
If you're really trying to maximize the performance and minimize downtime, you can spend some time pulling out the DDL for your indexes and constraints from the source - and have them scripted. Then only export the data, not the indexes and constraints, and after the data is imported use your DDL scripts, with high degrees of parallelism, to create indexes and constraints afterward. Don't forget to alter the index objects to remove the parallelism afterward so not to leave a bunch of high parallel indexes in place. This method can usually perform much faster than letting data pump do this.
Test well, and look for objects that don't migrate correctly or well with data pump and potentially use SQL scripts to bring them over manually.
Look for opportunities with some objects, for example meta data or DDL that doesn't change, to pre-create on Exadata before taking the downtime and starting the migration.

DB migration from AIX to Linux

Dear Experts,
We are planning to migrate our existing 10g database of 11.5.10.2 from AIX to Linux. Can anyone share their experiences? Some docs/URLS will be helpful. One of my friends told that it takes more than 36 hours to complete the database migration. Is it really true? The current database size is approx. 100GB.
After the migration does, apps function as usual?
Thanks in advance.
SA

Hi,
You can use export/import or transportable tablespaces to migrate the database.

How long the task would take? Depends on the hardware resources you have. The best practice is to try this on a test instance first.

4.6C migration from HP-UX to Linux

Hi all,
we are planning to move the current 4.6C environment from HP-UX to Linux platform. we need help with a couple of things that are posted below.
1. Is 4.6c compatible on RH Linux 11.31.
2. Do we need a seperate liscense for Linux or can we use the existing one.
3. Can we install a fresh installation of 4.6C on linux and import the DB from teh present working environment. Is this the way it is done.
4. Can we upgrade the DB from Oracle 9.2 to 10.4 due the migration process.
Your hellp will be appreciated.

Dear
1. Is 4.6c compatible on RH Linux 11.31.
2. Do we need a seperate liscense for Linux or can we use the existing one.
3. Can we install a fresh installation of 4.6C on linux and import the DB from teh present working environment. Is this the way it is done.
4. Can we upgrade the DB from Oracle 9.2 to 10.4 due the migration process.
1. There is no Red Hat 11.31, only HP-UX 11.31 and Red Hat Enterprise Linux 5 (or 4).
2. After migration, you hardware key changed, you need to renew your license. You do not need a separate one
3. for OS/DB Migration, check: http://service.sap.com/osdbmigration
4. There is no Oracle 10.4, only 10.2.0.4 ! If you want to use Oracle 10.2.0.4 you'd need the 46C_EX2 kernel
You should also take care, that native installation for 46c is 32bit only (for Linux). However, we have a prepared 46c installation CD for 64bit installations on linuxx86_64 (with kernel 46c_EXT -> later upgrade to 46c_EX2). You can request this CD via an OSS call on BC-OP-LNX-X64.

SAP Printer migration from AIX to windows

Dear Experts,
We migrated our ECC from AIX to Windows.
We want to migrate printers from AIX to windows.
Do we have to create queues from scratch in SPAD?
Can we use existing queues in SPAD?
Please guide what all steps are required.
Your help will be highly appreciated!
Thanks,
Harry

Hi Hary,
For windows environment you need to change the spool server hostname in SPAD and activate all the relevant printers.
Please check whether you had any network printers configured on AIX host. You can use command
smitty spooler or
lpstat -W -p<queuename>
If there are any spoolers configured for SAP system, you need to recreate them on windows.
Hope this helps.

Hi,
1) Does oracle support this kind of migration?Yes.
2) Is this achievable, without involving any functional consultants? You do not need any functional consultants for this migration.
3) Can anyone help with some metalink notes or document on this migration?Please see these documents.

Migration from HP UX to Linux

HI All,
We are just migrating OS from HP UX to Linux .But we are not touching database.In ABAP System there is no instance ID.So after migration all the application need not to be reinstalled.But in java there is unique instance id registered with java CI .So we need to again install application .Otherwise application server don't get synchronized .Is there any other way so that after migration also all applications are synchronized.We need not to manually reinstall .

Migration from AIX Oracle8i to Solaris Oracle8i?

Hi,
I wonder how to migrate Oracle 8i (8.1.7) on AIX to Oracle
8i (8.1.7) on Solaris?
The Oracle version is the same, but only the O.S platform is
different. I have found the migration information from Oracle
web site but it only talks about migration between different
database.
Thanks.

> In our organisation, we are planning to migrate from AIX6.1 to Solaris x64. The processor which we'll be using is UltraSPARC+IV processor.
Well - I think you're mixing a few things up here.
Solaris x64 refers to Solaris on the Intel or the AMD processor (x64 == x86_64 == AMD64)
UltraSPARC IV+ refers to a CPU developed by Sun (now Oracle).
> 1. Which guide to refer for moving the SAP System from AIX6.1 to Solaris
There are no specific guides for OS migrations. You use the heterogeneous system copy approach. However, migrating a database and/or operating system requires a certified migration consultant on-site doing the migration. If you do it yourself you'll loose support from SAP for problems during the migration and for the target system (see http://service.sap.com/osdbmigration).
> 2. Is UltraSPARC+IV processor is supported for Oracle 10g
Yes. Solaris 10 on SPARC Is supported.

Oracle E-business Suite release 12.1.1 migration from AIX to OEL on OVM

Hi
We will be migrating our current Oracle E-business suite release 12.1.1 production environment from AIX to OEL using OVM. We are experienced in migrating from one platform to another on single box but this is the first time we will be using OVM.
We will be gratefull if somebody can provide us the right path to migrate to OVM, my understanding is:
1. Setup Hypervisor, install OVM guests OS using OVM templates
2. Install E-business suite environment using OVM templates
3. follow Export / import document to migrate E-business suite environment
need suggestions
Thank You
Shahrukh yasin

No. Do not use the EBS templates.
1. Get OVM up and running.
2. Install OEL guests.
3. Check requirements for running OEL on EBS 12.1. They are different for different version of OEL. There are several oracle support articles detailing the requirement from OEL4 thru OEL6. I personally would use OEL5.
4. Clone your DB and app tops and get them working.
5. When you get ready to cut, refresh your DB. You can use datapump but it will take some time depending on how much data you have. You may want to upgrade your DB. If you're running anything less than 11.2.0.3. If you do, then datapump is the best option. At least in my opinion. There are several issues with running 12.1 and 11.2.0.3. Make sure you address them. There are several support articles detailing them. Oracle 10 database isn't supported on OVM. 10 isn't offically supported at all anymore.
6. Rerun you clone scripts on your app tiers and reconfigure your app layout.

Please help me to understand the following scenario of ORACLE APP'S migration.
One of my client currently using Oracle APP'S ver 11.0.3 DB version 8.0.5 running on IBM AIX platform.
Currently three customized module under operation with 50 forms and reports.
Also some external application integrated with the current oracle financial 11.0.3.
The client is more interested to migrate their platform to linux based server.
They wants to move the current set up to the new version EBS along with the existing customized module. (My question is it possible to migrate the customized module to another platform. AIX to Linux)
If so , where i can find the right document to explore more idea of this scenario of migration.
Thanks in advance.

ram,
I am going to do the similar upgrade with replatform at the same time. I collect the information from forum and finally get an indicator to how to do it. You need to read the "Upgrading the Oracle Applications", B19297-01
"Installing Oracle Applications" B19296-01 and
"Maintenance Utilities" B19300-01
The documentation mentioned the way for upgrade an 11.0 version of EBS to latest release including some pre-upgrade tasks including the database version upgrade to work with 11i, etc.
Hope this help.
