Configuring Baseline Libraries

Baseline libraries are the permanent repositories for application components. Use the baseline configuration function to specify physical baseline library names and to set the following related parameters:

The technology or file type used to store current and prior versions of components
How many prior versions of components are held in baseline libraries
Whether components are copied to separate production libraries as well as to baseline libraries when a change package is installed.

If you have set the parameter for Keep Baseline by Site on the Application Parameters - Part 1 of 4 panel, baseline libraries must be configured for each site. See Configuring Remote Sites for details.

Allocating Baseline Libraries

Select Option B on the Update Application Administration Options panel. The Application - Baseline Configuration Part 1 of 2 panel (CMNCBAS1) is displayed.

The following table describes the field of the Application - Baseline Configuration Part 1 of 2 panel (CMNCBAS1) and the information that you can enter when you create new libraries.

Field	Description
Type	Type the library type. Enter a * to select from the list of valid library types.
Levels	Enter the number of baseline levels to maintain for each library type. The range is from 2 to 10. Baseline libraries with storage means SD can retain a maximum of 999 levels; LA can retain up to 255.
Install in prd	Enter 'Y' if the library type is to be moved into the production libraries upon installation. Enter 'N' if the library type is not to be moved into the production libraries. Enter 'C' if the movement of the library type into the production libraries is dependent on their existence at the site.
Baseline storage means	Specify the means of maintaining the baseline libraries. Valid values for this field are as follows: SD - STACKED REVERSE DELTA - The 0 level baseline version is stored in a PDS or PDSE. All prior versions are stored as reverse delta records in a single PDS or PDSE. NOTE: This is the most efficient storage means for text components that can be compressed with delta technology. P - PDS or PDSE - The 0 level baseline library is a PDS or a PDSE, and each prior version level is stored in a separate PDS or PDSE library without compression. H - Hierarchical File System - The 0 level baseline library is a zFS directory, and each prior version level is stored in a separate zFS directory without compression. L - LIBRARIAN managed master files LA - LIBRARIAN ARCHIE managed master files PV - PANVALET managed files

To update an existing library, type S to select a row to specify the actual data set names for the item. The Application Baseline Configuration Part 2 of 2 panel (CMNCBAS2) is displayed.

The Application Baseline Configuration Part 2 of 2 panel (CMNCBAS2) specifies the names of an application's baseline libraries. The rows are already generated when you access the panel. From this panel you can verify or allocate (specify V or A) the baseline library data sets. ChangeMan ZMF uses these names when it creates batch jobs to ripple an application's baseline libraries after a change package has been installed. These libraries must exist and ChangeMan ZMF must be able to update them.

If you have set the parameter for Keep Baseline by Site on the Application Parameter Part 1 of 2 panel (CMNGLP01), baseline libraries must be configured for each site. See Configuring Remote Sites.

In a row of the Application Parameter Part 1 of 2 panel (CMNGLP01), type A or V and press Enter to allocate or verify these baseline library. Verify will display the allocation details.

Note

This option is not available for Librarian or Panvalet.

If you typed V in a row, the Dataset Information panel (CMNDSINF) is displayed.

If you verify, and a baseline library data set does not exist, the long message "CMN2650I - Unable to allocate dsname dataset", and *Error is displayed in the STATUS column next to the data set name.

If the dataset is a PDSE then a different panel CMNDAIPE is displayed.
