Reg: System Copy for JAVA stack

[Former Member]

We have Solaris sparc10 machine on which net weaver 2004s is installed with oracle database 10.2.0.2 (only java stack)and SAP GRC is running on the JAVA stack. The Unix box is a leased one. It is going to expire so we have to copy the entire application onto another Unix machine which would have the same OS . Has anybody done system copy for JAVA stack and if yes can anybody help us.

Do we have to go for a system copy or else we have a method where we can keep the same host name and copy the entire application.

Thanks in advance .

Hi,

You can do by using the SAPINST export-import method or the filesystem copy.

If you want to do it in export-import method, using SAPINST then you have to copy the filesystem /usr/sap/<SID> to the destination directory. If the hostname is different than the source system, follow the SAP note 757692 to change the hostname.

If you want to do the filesystem copy, just copy the entire file system which are related to SAP to the traget system with the samekind of authorization(Including Home Directory of the <sid>adm and ora<sid>). Have to re-link the database with the below commands..

Re-link :

For executables: oracle, exp, imp, sqlldr, tkprof, mig, dbv, orapwd, rman, svrmgrl, ogms, ogmsctl

% cd $ORACLE_HOME/rdbms/lib

% make -f ins_rdbms.mk install

For executables: sqlplus

% cd $ORACLE_HOME/sqlplus/lib

% make -f ins_sqlplus.mk install

For executables: dbsnmp, oemevent, oratclsh

% cd $ORACLE_HOME/network/lib

% make -f ins_oemagent.mk install

For executables: names, namesctl

% cd $ORACLE_HOME/network/lib

% make -f ins_names.mk install

For executables: osslogin, trcasst, trcroute, onrsd, tnsping

% cd $ORACLE_HOME/network/lib

% make -f ins_net_client.mk install

For executables: tnslsnr, lsnrctl

% cd $ORACLE_HOME/network/lib

% make -f ins_net_server.mk install

If the target hostname is different, follow up the above mentioned note.

Hi,

I would suggest you to go for homogenoeus system copy.

Hi this was the approach suggested by one of my team mates .

I didnt get this approach .

1. Isolate new host from DNS lookup, give it same hostname.

2. Install SAP instance with same SID, instance numbers as current one.

3. Install DB software on new host (same patchset, one-off patches).

4. Define cut-over time from business for existing installation.

5. Shutdown system, copy all database files to new server.

6. Unix task: IP switch between old and new server.

7. Start instances on new server.
