NetBase ADAGER Interface
This interface is used in shadowing environments and allows for ADAGER database changes that
are performed on the master system to be automatically sent to the shadow system and be performed
on the shadow copy of the data. In order to use the NetBase ADAGER Interface, a special
command file, ADAGER.PUB.NETBASE, must be used to create an ADAGER job to perform the
structural changes.
All commands input into this are put into a job stream. When the job stream executes, it runs the
program ADAGER.PUB.REGO. Once ADAGER has successfully completed the changes on the master
system, NBADAGER writes all of the ADAGER commands into the shadow transport file,
NBM.IPC.NETBASE, and sends them to the shadow system.
When the posting process, NBPOST, receives the ADAGER commands, it automatically puts the
database into a queue state. NBPOST then invokes ADAGER on the shadow system to make the
same changes as were made on the master. A temporary file with the name Annnnnn (where n is a
random digit) is created in the group with the root file on the shadow system. This file contains the
ADAGER commands. It will be automatically purged upon completion of the ADAGER changes.
Once the ADAGER changes complete successfully, NBPOST does a roll forward on the database.
Requirements

• Version of ADAGER equal to or greater than 941201
• NetBase version 9.6
• NetBase directory program entries for NBADAGER.PUB.NETBASE and @.PUB.REGO
