Option 3 – FSU Installation

Note, that FSU installation (stage 1) must immediately follow the FSU preparation job.

You can run stage 1 of the installation while the system is up and running. There is no need to shut down any partitions.

When you select option 3 FSU Installation, the following panel is displayed:

TAPE UNIT ADDRESS............ ___         For valid addresses see HELP          
Enter 1 if FSU is to be done from virtual tape, else enter 2 for real 
tape.      
VIRTUAL TAPE................. 2           FSU from virtual (VSAM) tape?         
If virtual tape is selected, enter:                                             
VSAM FILE NAME............... _______     Unique name of the VSAM file          
Enter 1 for YES and 2 for NO to the following questions.                        
GEN-LIB REFRESH.............. 1           Do you want to refresh Generation     
                                          part?                                 
REORGANIZE DTSFILE........... 2           Do you want to reorganize DTSFILE ?   
BACKUP LIBRARIES............. 1           Do you want to backup base libraries? 
BACKUP DTSFILE............... 1           Do you want to backup the DTSFILE ?   
OWN POWER PARAMETERS......... 2           Do you have your own POWER parameters 
                                          (Phase, Partition allocs, Partition   
                                          size, or PFIX value) ?

TAPE UNIT ADDRESS: Specify the address (cuu) of the tape unit used for FSU and for creating the backups.
VIRTUAL TAPE: Enter 1 if you want to do an FSU from virtual tape. If you select virtual tape, you must enter the VSAM file name of the file holding the tape image.
In case you specified a virtual tape, a real tape is used for reorganizing the DTSFILE as well as for creating backups of libraries and the DTSFILE. The real tape is used on the same address as the virtual tape.
GEN-LIB REFRESH: This selection appears only for those users who have installed the Generation Feature.
Specify whether you want to upgrade the generation library during FSU. If you enter 2 (NO), the entry for the generation library is removed from the system history file. The sublibrary (PRD2.GEN1) where the Generation Feature resides is not upgraded. Consequently, no service for the Generation Feature (supervisor generation macros) will be applied in future.
REORGANIZE VSE/ICCF DTSFILE: Specify whether you want to reorganize the refreshed VSE/ICCF DTSFILE. Reorganization of the VSE/ICCF DTSFILE helps improve system performance.
BACKUP LIBRARIES: Specify whether you want to back up the VSE system libraries IJSYSRS, PRD1, PRD2.SCEEBASE, PRD2.TCPIPB and PRD2.TCPIPC. If you do not have a backup available, specify 1 (YES) in the BACKUP field for the libraries. (Job DTRFSU12 is created.)
BACKUP VSE/ICCF DTSFILE: Specify whether you want to back up the existing VSE/ICCF DTSFILE. If you do not have a backup available, specify 1 (YES) in the BACKUP field for the VSE/ICCF DTSFILE. (Job DTRFSU13 is created.)
In case of an error situation, you should have a job in your VSE/POWER reader queue to restore your original VSE/ICCF DTSFILE.
OWN POWER PARAMETERS: Specify whether you want to use a VSE/POWER phase that you have generated yourself. If you specify YES, another panel appears and prompts you for the name of the VSE/POWER phase and allocation values, such as the allocation size and the SET PFIX value for the VSE/POWER partition. You also have to enter the name of the library where your VSE/POWER phase is stored. It is recommended to make a copy of your own VSE/POWER phase.

This dialog creates a job with the default name DTRFSU. From the Job Disposition panel, you can submit the job to batch, file it in your default primary VSE/ICCF library, or both.

After you have entered all data, the Job Disposition panel is displayed, and you can submit the job. You can change the class on the Job Disposition panel. Note, that the startup for stage 2 of FSU activates seven partitions only (BG, F1 to F5 and FB). In stage 2 all jobs run automatically in partition BG.

Continue with FSU Installation – Stage 1, independent of whether you install a service refresh or perform a version upgrade.
