Descripción: So, now we got both systems up and runing, but TARGET DB2 storage groups point to source HLQ. So we have to update TARGET DB2 catalog to point to new HLQ. To do this we use REXX code to select all storage groups and generate DDL to:
1.- Alter all depenent tablespaces and indexspaces to a temporal storage group -> SYSADM.TEMP.CHTSSGT
2.- Drop all storage groups -> SYSADM.TEMP.DROPSTO
3.- Create all storage groups with new HLQ (VCAT) -> SYSADM.TEMP.CREASTO
4.- Alter all depenent tablespaces and indexspaces to their original storages groups -> SYSADM.TEMP.CHTSSGO
The JCLs that automates all this stuff are RENSTOGC (generates DDL to change STOGROUP VCAT) and ALTSTOG (executes it)

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 .
10.- Instalación zlinux. Instalación utilidades.
Una vez tenemos instalado el nucleo del sistema operativo, procedemos a instalar las utilidades estándar del sistema (ssh server, etc ...).
6.- Instalación zlinux. Configuración DASD
En este paso vamos a configurar los volumenes que utilizaremos para el root file system de la debian s390 y el volumen para la paginación del sistema.
5.- Instalación zlinux. Configuración usuarios
En este paso vamos a configurar los usuarios del futuro linux debian para s390.
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.
