Copy or rename R/3 w-out installing

Copy or rename R/3 w-out installing

Need to move or copy R3 to another server or change the SID or instance number? It can be done without an install quite easily on Unix/Oracle systems.

Move or copy SAP R3 on Unix/Oracle, changing hostname, SID and instance without installing R3 or Oracle.

<SID>        = SAP SID
<HOST>       = Host name
<##>         = SAP Instance number
<SAPINSTNAM> = SAP Instance name (e.g. DVEBMGS00)
<SAPORAHOME> = Home directory of SAP Oracle user
<SAPADMHOME> = Home directory of SAP Administrator
<SAPPROFILE> = Directory containing SAP profiles
<ORATNSHOME> = Directory containing oracle TNS control files
<ORAHOME>    = Oracle Home

  1. Stop SAP and Oracle (shutdown normal)

  2. Copy all files under /oracle/<SID>, /usr/sap/<SID> and /sapmnt/<SID>

  3. Rename and/or edit following changing hostname, SID and instance number
        <SAPORAHOME>/.init<SID>.ora                                             
                /.dbenv_<HOST>.csh                                          
                /.dbenv_<HOST>.sh                                           
                /.sapenv_<HOST>.csh                                         
                /.sapenv_<HOST>.sh

    /usr/sap/PRD/<SAPINSTNAM>

  2. Relink Oracle executables
        cd <ORAHOME>/rdbms/lib                                                  
    edit nmliblist and change <SID>                                         
    make -f ins_rdbms.mk install

  3. Create script to build new DB control files
        svrmgrl                                                                 
    connect internal                                                        
    shutdown normal                                                         
    startup nomount                                                         
    alter database backup controlfile to trace resetlogs;                   
    alter database open;                                                    
    alter system switch logfile (one for each group)                        
    shutdown normal                                                         
    exit                                                                    
    rename the trace file in <ORAHOME>/saptrace/usertrace/ to control.sql   
    edit this file                                                          
      delete everything but the CREATE CONTROLFILE command                  
      change the CREATE CONTROLFILE statement to                            
        CREATE CONTROLFILE SET DATABASE <SID> RESETLOGS ARCHIVELOG          
      change <SID> and alter any file location changes

  4. Remove or rename old control files

  5. Build new DB control files
        svrmgrl                                                                 
    connect internal                                                        
    startup nomount                                                         
    @control.sql                                                            
    alter database open resetlogs;                                          
    exit

          sapdp<##>    32<##>/tcp
      sapgw<##>    33<##>/tcp
      sapms<SID>   36<##>/tcp
