Un-officially SAP OSDB Migration Project done !!


Another project have been completed by me this year.

Since the sister company (formerly I maintain) moved to hyperconverged Nutanix and used Acropolis as its hypervisor, there is a SAP R / 3 4.7 ext 200 system running on HP rx4640 machine with HPUX 11.23 OS and Oracle 9.2 database server that must be migrated to a Nutanix machine . HP rx4640 machine is not extended maintenance support. While the system, SAP R / 3 4.7 ext 200 is also not supported by SAP both SAP instance and database server.

Target using Linux OS SLES 11 SP4 and DB2 database server 9.7 FP 5.

Broadly speaking the migration process is :

    – Export existing data in SAP R / 3 4.7 ext 200 on HPUX source machine
Install DB2 9.7 database server on target Linux
Install Central Instance on Linux target
Install Database instance in Linux target by selecting System Copy and export result (process no.1) as imported data.

The export process runs smoothly. Problems begin to emerge during process no.4 of them:

The process of database load had stopped because the file system is full sapdata. Solution: extend the sapdata partition and the file system
The database load process was stopped again because the file system is a full archive log. Solution: extend the partition and add the number of LOGARCHIVE second files.

After the import process is complete, there are still more problems that arise, the SAP kernel 6.40 used does not recognize the linux 3.0 kernel (used SLES 11 SP 4) and DB2 9.7 database. The solution is download the latest version of SAP kernel 6.40 EX2 patch (version 414).
