STEP 0: Initial Scenario
The main purpose of this video-tutorial is to show you how to clone a DB2 subsystem to other subsystem running in the same Z/OS LPAR. Each step is explained with a video (screen cast). It is supossed that you have two DB2 subsystems, in this case DB8G (source) and DBF (target), both up & running. The procedure is automated in three main steps contained in library SYSADM.ODBCLONE. First step is related with the physical COPY from SOURCE datasets to TARGET DB2 datasets. While the remaining, are related with making target DB2 BSDS & CATALOG consistent with the location of the DATASETS copied from source subsystem
STEP 1: Copy Source DB2 DataSets to Target DB2
First of all, we execute REXX code to simulate DB workload. This workload consist in inserting on row per second in table sysadm.prv. Second, we stop TARGET (/-DBF STOP DB2) and delete all its datasets except the TARGET SDSN libraries and installation jobs . Finally, we proceed to COPY SOURCE datasets to TARGET DB2, while renaming HLQ (High Level Qualifier). The JCL that implements this is called CPYREN and is executed while source DB is up and running.
1.- Instalación zlinux. Introducción
Pasos preliminares a la instalación. Descargar el runtime necesario (zlinux.tgz) con dispositivos emulados y configuraciones necesarias para la instalación de debian en arquitectura s390 emulada (Hercules).
STEP 4: Clone checking
Finally, we compare rows from the table that was been modified while source DB2 was clonned. Josep Vidal - System Programmer. For more questions you can reach me at: josepvidalcanet@gmail.com .
