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)

This is automated with job RBLDLOGI which prints DBF.BSDS01 log inventory, reads its output (SYSADM.TEMP.PRNTBSDS) and generates a JOB (SYSADM.TEMP.JU004) to: 1.-) Change BSDS HLQ 2.-) Delete LOGCOPIES with source HLQ 3.-) Create new LOGCOPIES with target HLQ and START/END RBAs taken from log inventory output. At this point we can start target system.Target DB2 subsystem is started in MAINTENACE MODE: /-DBF START DB2 ACCESS(MAINT)
Práctica del servidor HTTP. Implantaicón de un cluster WEB Objetivo: Crear un cluster WEB para aumentar el nivel de servicio (disponibilidad y rendimiento) balanceando las peticiones entre los dos servidores backend WEB z/os. Requisitos: * 1 LPAR emulada zlinux (instalada en la práctica anterior) * p390.uv.es: LPAR z/os corriendo el servidor IBM HTTP Server V5R3M0 (VLC) * zeuszvm.moppssc.ibm.com: LPAR z/os corriendo el servidor IBM HTTP Server V5R3M0

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.
Demo sobre persistència de sessions. En el cluster de la gestió acadèmica s'aturen tots els nodes. Posteriorment, s'alça un i es comprova que les dades de la sessió es recuperen sense problemes.
