System copy from newly upgraded EHP7 system

[Former Member]

We have System A with newly upgraded to EHP7

SAP kernel 741_REL

DB  Oracle 11.2.0.4

OS Linux RHEL 6.0

We have another System B with EHP6

SAP kernel 721_REL

DB  Oracle 11.2.0.2

OS Linux RHEL 5.3

Now We  want system B as a copy of A .We will upgrade OS and DB at a same level as System A has. So can we gonfor homogeneous system copy?

I am not understanding how we can get EHP7 on system B.

Or will SWPM(software provisioning manager) can do system copy with SAP component copy?

Please suggest

Hello All,

We have scraped our System B and cloned our system A on system B host.

we have now all mounts same as system A like  /sapmnt/A and /oracle/A on system B.

Now we are going to use SWPM 1.0  with system Rename option.

will update you once it is done successfully.

Thank you.

Hi Spr,

Follow below steps

1) Upgrade OS from RHEL 5.3 to 6.0

2) Upgrade database from 11.2.0.2 to 11.2.0.4 including SBP similar to System A

3) Perform full backup of system A

4) Restore the backup to system B.

5) Perform post restore activities.

For database I have idea about the control file change. But what about the sap side. Do I need to run SAPinst for EHP 7after backup restore.

Hi Spr,

Once you restore backup of system A , system B will already have EHP7.

You need to make the SAP kernel levels on System B same as System A.

Hello Thank you for your valuable reply . It has provided me the road map to proceed !

So once kernel has been made at same level I need to run SWPM (software provision manager) for system Rename and then  i can bring system B up right?

[divyanshu_srivastava3]

Rename using SWPM ?

Then what have you done with control files ?

[Former Member]

Yes Control files rename has done but still My usr/sap/Sid is pointing to System A but it should be System B. So what are the changes we need to do for changing SID of SAP system also.

[divyanshu_srivastava3]

Which system is pointing to A ? The real A or target B ?

[Former Member]

target system

hi,

Please go for homogeneous system copy.

For this,

1. a)First DB export from System A using sapinst tool.

b) Stop System B

c) Upgrade OS and DB.

d) Import DB to System B using sapinst.

e) Run DB instance installation.
