Upgrading strategy

Post by Guest » Fri May 16, 2003 7:36 am

I´m planning an upgrade
FROM:
Solaris 2.6 (32 bits)
Oracle 8.0.6.3 (32 bits)
Sap 31I

TO:
Solaris 9 (64 bits)
Oracle 9.2 (64 bits)
SAP Enterprise (4.7)

Which will be the best strategy of attack?
Thanks a lot,
Xman

TO:
Solaris 9 (64 bits)
Oracle 9.2 (64 bits)
SAP Enterprise (4.7)

1. stop sap
2. brbackup
3. unix backup of SAP related files
4. use ufsdump to backup Unix files
5. re-install completely server
6. install Solaris 9 64-bit
7. instlal Oracle 9.2 64-bit
8. restore unix backup of SAP related files
9. setup sidadm or orasid accounts
10. try to start DB
11. try to start R/3

If all Ok, plan 4.7 upgrade.

Well, this seems so easy that I'm confused.

you said I can:

brbackup the 3.1I (806) database
level 0 backup
format server
install solaris 9 (64bits)
install sap 3.1I (again)
install oracle 9 (64bits)
and then brrestore sap datafiles
then upgrade to SAP Enterprise

just like that?

It's ok to restore the database files from the 32bits environement to 64bits?
Can I espect small problems that require high level of knowledge of Solaris anda Oracle?

I usualy follow SAP manuals. :D

well - it's not sooooo easy ... just a small example. delivered with sap there are 32bit binaries - but also 64bit binaries (svrmgrl for example). you have to adapt environment, paths a. s. o.

there might be other obstacles.

also i'm not sure, that you can simply restore 32-bit db-files to a 64-bit database, when we we're migrating we had to dump the database to files ...

I tried it with 8.1.7 and yes, the database format does not change. Only binaries change.
brbackup the 3.1I (806) database
level 0 backup
format server
install solaris 9 (64bits)
install sap 3.1I (again)
install oracle 9 (64bits)
and then brrestore sap datafiles
then upgrade to SAP Enterprise

Yes, these are the main steps. You may get a few problems here and there but OSS notes are there for you... And there is always SAPfans to help too!


Make sure you read the links I posted before. There was a 64-bit locale problem on Solaris 8. It might be the same on Solaris 9.
