SAP SWPM Checks Windows Virtual Hostname Setup

When you come to use SWPM for the first time to copy a SAP system which has a virtual hostname defined and used, be aware that the SWPM has in-built checks to ensure that the Windows registry is correctly configured according to SAP note 1564275.

If you’ve not fully implemented the note configuration in the Windows registry, even if you’re using the “SAPINST_USE_HOSTNAME=<hostname>” SAPInst.exe parameter, the SWPM will show an error and exit.

My specific setup was missing the DisableStrictNameChecking setting.  After adding this into the registry, I was able to launch SWPM.

SAP Netweaver 731 Oracle Create DB Statement

By default, when you use the Software Provisioning Manager (SWPM) to create a new NW731 Oracle database, it will generate and run an Oracle “CREATE DATABASE” statement as follows:

SQL> CREATE DATABASE DB1 CONTROLFILE REUSE 
MAXLOGFILES 255
MAXLOGMEMBERS 3
MAXLOGHISTORY 1000
MAXDATAFILES 1000
MAXINSTANCES 50
NOARCHIVELOG
CHARACTER SET UTF8
NATIONAL CHARACTER SET UTF8
DATAFILE '/oracle/DB1/sapdata1/system_1/system.data1' SIZE 350M REUSE AUTOEXTEND ON NEXT 20M MAXSIZE 10000M EXTENT MANAGEMENT LOCAL
DEFAULT TEMPORARY TABLESPACE PSAPTEMP TEMPFILE '/oracle/DB1/sapdata1/temp_1/temp.data1' SIZE 50M REUSE
AUTOEXTEND ON NEXT 20M MAXSIZE 10000M
UNDO TABLESPACE PSAPUNDO DATAFILE '/oracle/DB1/sapdata1/undo_1/undo.data1' SIZE 100M REUSE AUTOEXTEND ON NEXT 20M MAXSIZE 10000M
SYSAUX DATAFILE '/oracle/DB1/sapdata1/sysaux_1/sysaux.data1' SIZE 200M REUSE AUTOEXTEND ON NEXT 20M MAXSIZE 10000M
LOGFILE GROUP 1 ('/oracle/DB1/origlogA/log_g11m1.dbf') SIZE 200M  REUSE ,
GROUP 2 ('/oracle/DB1/origlogA/log_g12m1.dbf') SIZE 200M  REUSE ;

Notice that both the character set and national character set are UTF8.
