host name and ip adress is will be stay same.

whats your best methodology for that?

Hi

we could open the oracle database on new server . ı wonder sap side configuration steps like sap profiles , os user profiles etc.

If you could open the Oracle database, you can simply use System Copy using Backup/Restore Method.

Just keep in mind the following.:

1. Restore and Recover database.

2. Start SAPinst for System Copy.

3. Select "System copy using Backup/Restore" method.

4. When installation ask to restore and recover database, just create CONTROL.SQL file in Temporary Installation directory (C:\Program Files\sapinst_dir\XXXX") with following lines.

STARTUP
EXIT

5. Continue with SAPInst installation.

Perhaps you could explain which host are involved, and for which hosts you did or did not change host name and ip address ...

ı mean like that :

1- ı want to restore oracle and sap data to new server with same host name and ip adress

2- ı backed up all related data

3- ı shut down the system

4- ı open the new server and restore the data on it

5- ı change the host name and ip adress with former systems

6- ı create related os users and group on new machine

7- ı check the permission all file systems

8- ı open oracle at new machine

9- but startsap does not work and giving that error

thanks

Hi,

Check if firewall is running...

Also disable SELinux on RHEL server.

Post startup log contents from <sid>adm users home directory.

Thanks, a bit clearer now...

How many hosts are involved? Are SAP instances and Oracle database on the same host?

If I correctly understood, Oracle now is running on a new machine, but with same hostname and same ip?

And SAP is on the same host?

Is sapstartsrv process running?

If it isn't: What happens if you try to start it from command line?

And please show your exact startsap command and exact error message.

Is it the same startsap command that was used on the previous machine?

- exist only one host hosting db and sap instance

- yes oracle is running on new machine with same hostname and ip adress

- sap is on the same host with db

- normaly sapstartsrv didnt work ı started it manually "sapstartsrv pf=<start profile> -D" after that tried to start again but result was same

-ı run startsap command with <SID>ADM user

-yes because sap executables taken from previous machine (/usr/sap , / sapmnt etc....)

-error message is :

cat startsap_DVEBMGS00.log

Hello,

Without logs it would be difficult to help you out..

Try upgrading "sapstartsrv" with latest one...

Check [SAP Note 877795 - Problems w/ sapstartsrv as of Release 7.00 & 6.40 patch 169|https://service.sap.com/sap/support/notes/877795]

Again, post sapstartsrv.log and startup logs which can give you more details about error.

Regards.

normaly sapstartsrv didnt work ı started it manually

So I suppose SAP files are missing from your root file system; please check!

Not sure about RHEL; in our SuSE linux it is /etc/init.d/sapinit, and symbolic links in /etc/init.d/rc*.d

So now sapstartsrv is running? Which user? Should be <sid>adm.

And as asked by Rajesh :

More log files would help.

Hi,

Curious to know which method are you using for the movement of SAP / DB server?

Br,

Venky

[Former Member]

hi

snapshot copy is used for that . all file systems is mounted to new server

[Former Member]

Hi,

I don't think there is a need for re-configureation apart from SAP License since the hardware key gets changed.

Are you sure that there are no other changes to other components?

Br,

Venky

hi

sure hardware is changed but even oracle is opening but sap does not start using sapstart script at new server.

all sap file system moved to new server like /usr , / sapmnt etc...

hostname and ip adress is changed as usual

Hi,

In that case, reffer the following notes.
