Issue/Introduction
Would like to verify if the following variables in the VARBLIST member are used when upgrading to 19.0
In particular the VARBLIST variables listed below:
GJSDMLOW = 2001 Starting page of SYSTEM.DDLDML area
GJSLOLOW = 3501 Starting page of SYSTEM.DDLDCLOD area
GJCCTNPG = 1600 Number of pages (blocks) in 'DCCAT'
GJCCLLOW = 1606 Starting page of CATSYS.DCCATLOD area
GJCCLNPG = 250 Number of pages (blocks) in 'DCCATL'
GJCCXLOW = 1861 Starting page of CATSYS.DCCATX area
GJCCXNPG = 120 Number of pages (blocks) in 'DCCATX'
Environment
IDMS - all supported releases
Resolution
The variables in the VARBLIST that are related to database allocation are NOT used for an UPGRADE CONFIGURATION.
The variables mentioned are only used for 'Complete Base Configurations'. A Complete Base Configuration will use the variables related to allocation and page range parameters for your database files to create new dictionaries. When a Complete Base Configuration is being performed it is entirely up to you whether you choose to change the values from the defaults delivered or if you want to change them to meet you sites need or preference.
When you perform an 'UPGRADE CONFIGURATION' from an older release of IDMS to a new release (19.0), then the variables related to database file allocation and page ranges are ignored. An Upgrade Configuration preserves and operates with your existing dictionaries and database files and does not allocate, format, or initialize dictionaries or database files.
