NDVRDLVR Definition Delivery

• After NDVRDSEL is run (to select and validate the source system) and NDVRDCOR is run (to perform impact analysis on the target), NDVRDLVR performs one or both of the following functions:
• Migrates full Source or Executable (Load Module only) definitions from the source dictionary for all items contained in the NDVRENI file created by NDVRDSEL.
• Builds a Class/Attribute Structure in the source dictionary for all items selected by NDVRDSEL. When using an alternate vendor's migrator, use the Class/Attribute migration path to export entities selected by CA Endevor/DB. The Class/Attribute structure is also useful as an audit trail when copying the entire dictionary to a system where CA Endevor/DB is not installed.

The NDVRDLVR program performs its function by first reading the NDVRIPT file with the command syntax described below. It then invokes as many of the following CA IDMS compilers as are necessary for the action being performed:

• ADSOBCOM
• ADSOBTAT
• IDMSDDDL
• IDMSCHEM
• IDMSUBSC
• RHDCMAP1
• RHDCMPUT

The DDDL syntax required to add the CLASS and ATTRIBUTE structure (if needed) and extract the source statements and/or load modules is fed to the compiler internally by NDVRDLVR.

No Change Log Entries are created as a result of NDVRDLVR activity. This program has the capability to instruct the Change Monitor to refrain from logging. This is done to prevent entities in dictionaries, which are intermediate stops in the migration path from appearing as if they were modified since the last migration. Thus, NDVRDCOR will not falsely warn against modification overlay to entities, which were migrated in and migrated out without intervening updates except by NDVRDLVR. For this reason, any user executing this program will need to be authorized for NM-MODE=Y in the Security Class.
