The Global VCAT and BSDS1 data set names are generated using the DSN Prefix entered on the previous panel. Enter the required allocation information. Enter c on the command line and press Enter to continue to the next panel.

Note: If the Global VCAT and BSDS1 DSNs need to match a control data set naming standard at your site, they can be renamed in the JCL generated by the Customization Process before the JCL is submitted. CA Vtape only enforces the naming standard using the DSN Prefix during the Customization Process. The running product does not enforce this naming standard for these data sets. You will be reminded to rename these data sets if required during the appropriate step later in the Customization Process.

VTIP1400 --------------- CA Vtape Virtual Tape System ---------------- JCL Customization Options COMMAND ===> c C to Continue P for Profile Values PF3 to Previous DFSMS constructs and/or VOLSERs can be defined to control the allocation of the Global VCAT and BSDS1 data sets. The Global VCAT and BSDS1 should not be allocated on the same volume and should not be allocated on the DASD Buffer Pool volumes.

On this panel you chose whether you are going to customize CA Vtape to use Dynamic or Static Cache Management.

The panel defaults to Dynamic Cache Management. To take the recommended path of Dynamic Cache Management, enter c on the command line and press Enter to continue to the next panel. Proceed to step 10.

To take the Static Cache Management path, overtype DYNAMIC with STATIC, enter a c on the command line and press Enter to continue to the next panel.

VTIP145D --------------- CA Vtape Virtual Tape System ---------------- JCL Customization Options COMMAND ===> c C to Continue P for Profile Values PF3 to Previous Define CA Vtape CACHE Management - Specify "Dynamic" or "Static" - Dynamic Cache Management dynamically allocates DFSMS managed data sets using Media Manager I/O Services. - Static Cache Management pre-allocates and pre-initializes a fixed number of VSAM Linear data sets using Data-In-Virtual I/O services. In this mode DFSMS is not required. CA Vtape Cache Management: DYNAMIC ***

This panel is only displayed for Static Cache Management. If you chose Dynamic Cache Management, proceed to step 10.

Enter the required allocation information for the DASD buffer LDSs. Enter c on the command line and press Enter to continue to the next panel.

VTIP1500 -------------- CA Vtape Virtual Tape System -------------- JCL Customization Options COMMAND ===> c E to Edit Volumes Mbr C to Continue P for Profile Values PF3 to Previous DFSMS constructs or a volume list can be used to control the allocation of the DASD Buffer Pool Linear Data Sets. A Volume List Member can be defined in the SVTJCL library from this panel by specifying a member name that must start with VOL (e.g., VOLUMES, VOLIST1). The DFSMS constructs and the Volume List Member are mutually exclusive. Data Class: ________________________________ Storage Class: BPSTORCLAS______________________ Management Class: ________________________________ DASD Buffer Pool Volume List Member Name: ___________ ***

This panel is only displayed if you have chosen Static Cache Management. If you chose Dynamic Cache Management proceed to step 10.

Enter the Virtual Volume Size, the total number of Virtual VOLSERs that will be needed in the CA Vtape Complex, and the DASD Buffer Pool size. The number of Virtual Volumes defaults to 1000. The number entered is used to size the control data sets. 1000 works well for a software trial. If a production complex is being defined, the value should be increased to at least 100,000. Enter g on the command line and press Enter to generate the customization JCL, the Configuration Log, and the Configuration Member SUTPARMS.

Proceed to step 11.

VTIP160D -------------- CA Vtape Virtual Tape System -------------- JCL Customization Options COMMAND ===> g G to Generate Session Mode: Define PF3 to Previous Virtual Tape Volume Size (MBytes): 800_ A Virtual Tape Volume Size of 400, 800 or 2000 MBytes can be entered. The value entered is used to internally configure CA Vtape and to determine the size of the DASD Buffer Pool Linear Data Sets (LDS). 400 MByte Virtual Volumes = 40 MByte LDS 800 MByte Virtual Volumes = 80 MByte LDS 2000 MByte Virtual Volumes = 200 MByte LDS Define the maximum number of Virtual Volumes for the CA Vtape System. Enter a value between 100 and 1,000,000 Number of Virtual Volumes to Index: 100000___ Enter the DASD Buffer Pool Size (MBytes) determined from the analysis of your tape activity reports. The maximum value for 400 MByte Virtual Volumes is 2,621,440 MBytes. The maximum value for 800 MByte Virtual Volumes is 5,242,880 MBytes. The maximum value for 2000 MByte Virtual Volumes is 13,107,200 MBytes. DASD Buffer Pool Size (MBytes): 100000_____ ***

This is the panel displayed for Dynamic Cache Management. If you chose Static Cache Management, proceed to step 11.

The Virtual Volume Size defaults to 2000 MBs. This is the recommended value. Enter the total number of Virtual VOLSERs that will be needed in the CA Vtape Complex. The number entered is used to size the control data sets. 1,000 is the default and this works okay for a software trial. If a production complex is being defined, the value should be increased to at least 100,000. Enter g on the command line and press Enter to generate the customization JCL, the Configuration Log, and the Configuration Member SUTPARMS.

VTIP170D --------------- CA Vtape Virtual Tape System ---------------- JCL Customization Options COMMAND ===> g G to Generate Session Mode: Define PF3 to Previous Virtual Tape Volume Size (MBytes): 2000 A Virtual Tape Volume Size of 400, 800 or 2000 MBytes can be entered. The value entered is used to internally configure CA Vtape and to determine the maximum DASD allocation allowed for a single Virtual Tape Volume. If additional DASD space is needed, the Virtual Tape Volume will be kept, a scratch mount will be requested, and the application data set will go to multiple volumes. Define the maximum number of Virtual Volumes for the CA Vtape System. Enter a value between 100 and 1,000,000. Number of Virtual Volumes to Index: 10000_ ***

During the generation process the following screen will be displayed. The message block will change multiple times as different phases of the generation process are entered.

When the generation process is complete, you will be placed in a browse session to review the Configuration Log.

After reviewing the Configuration Log press PF3 and you will be placed in an edit session for the PREFIX.SVTJCL(DELETE) member.

The DELETE JCL member submits other jobs. As the member name implies, the other jobs contain delete statements.

Important! If you enter the DSN Prefix of an existing CA Vtape Complex into the panels and submit the DELETE JCL member, you run the risk of deleting the control data sets and the cache and backstore copies of the Virtual Volumes of that existing CA Vtape Complex. That is, you run the risk of creating a data loss situation.

Press PF3 to return to the Main Menu. Press PF3 again to leave the Customization Panels.
