Issue/Introduction

With Workload Automation CA 7 12.1 installed in the environment, what kind of information is being written in Datacom Datadictionary and the directory file CXX?

How often should a backup be taken?

Environment

Datacom/AD 15.1 

CA 7 12.1 

Resolution

Refer to Datacom Datadictionary.

Here is an extract: 

Datacom Datadictionary 

is a tightly coupled 

Datacom

 application facility. It manages and stores database structure definitions including predefined entities (or record types) and corresponding relationships. Interconnected by standard and internal relationships, the standard entities form the model for the database environment. This model assures that the format of the data stored in the database matches the expectations of a program.

As part of the Datacom/AD installation, the 

Datacom Datadictionary 

has various 

Datacom

 system and sample databases defined in the 

Datacom Datadictionary 

. Each structured database is promoted from a TEST to PRODuction status and then cataloged from the 

Datacom Datadictionary 

to the CXX.

• During the post-installation for many of the products that use 

  Datacom Datadictionary 

  , your 

  Datacom Datadictionary 

  is fully populated with the definitions required by the product. Therefore, you are not required to use any of the 

  Datacom Datadictionary 

  online or batch facilities to customize it.

CA 7 jobs  AL2DCA20, AL2DCA30 and AL2DCA40 that run DDUPDATE modify Datadictionary. 

DDRTVCAT, executed in AL2DCA30, catalogs the CA 7 data base structure found in Datadictionary to the CXX.  

The CXX contains the definition of the CA 7 data base in compressed format . Datacom cannot function without a valid CXX. 

DDTRSLM updates both Datadictionary and the CXX when importing CA 7 table structures. 

DDTRSLM  runs in AL2DCA40 and AL2DCA70. 

 

Backup of the CXX and Datadictionary should be run after the initial CA 7  installation and before/after running the HOLD ACTION of any CA 7 PTF for which a rerun of a CA 7 installation job is required. This is what CA 7 recommends to do. See Data Dictionary Backup
