DBMAINT Mode - DATACOM/DB Structure Maintenance › Disable and Enable Structures

Disable and Enable Structures

The CA Datacom Datadictionary DISABLE and ENABLE functions apply only to the definitions in CA Datacom Datadictionary. They do not affect the definitions in the CA Datacom/DB Directory. These definitions are still accessible by your programs. CA products (such as CA Dataquery definitions) that depend on synchronized definitions in CA Datacom Datadictionary and the CA Datacom/DB Directory cannot access the CA Datacom Datadictionary disabled definitions. The use of these functions by other products is dependent on the version level of the product. Check the product documentation.

CA Datacom Datadictionary automatically performs the DISABLE function when it executes the ADD, COPY, CREATE, DEFINE, MODIFY, RESTORE, TRANSFER, and UPDATE ATTRIBUTE functions.

Enable definitions that have been disabled.

When to Use the DISABLE Function

Use the DISABLE function to mark a structure or substructure as being unavailable for use by other CA products.

How to Use

Use one of the following procedures to perform this function:

• Select the DISABLE option on the DB Structure Functions Menu for the selected structure, fill in the prompter panel and press PF9 (APPLY).
• Enter the DISABLE command (see DISABLE) for the correct format and press PF9 (APPLY).
• Type the DSB margin command in the line number of the occurrence on a structure or index display panel. Enter the PROCESS command (press PF4), and press PF9 (APPLY).

If there are no errors, you receive the CA Datacom/DB Structure Maintenance Menu with a message confirming successful execution of the function.

When to Use the ENABLE Function

Use the ENABLE function to indicate that data defined in a structure or substructure is in synchronization with the CA Datacom Datadictionary definition and available for use by other CA products. This command enables the CA Datacom Datadictionary definition, not the CA Datacom/DB definition. Enabling a structure or substructure does not affect the definition in the CA Datacom/DB Directory (CXX). Therefore, you can enable a structure or substructure that is not synchronized with the CA Datacom/DB Directory or the data, but this can cause unpredictable results.

How to Use

Use one of the following procedures to perform this function:

• Select the ENABLE option on the Structure Functions Menu Panel for the selected structure, fill in the prompter panel, and press PF9 (APPLY).
• Enter the ENABLE command (see ENABLE) for the structure and press PF9 (APPLY).
• Type the ENA margin command in the line number of the occurrence on a structure or index display panel, enter the PROCESS command (press PF4), and press PF9 (APPLY).

If there are no errors, you receive the CA Datacom/DB Structure Maintenance Menu with a message confirming successful execution of the function.

Note: When you DISABLE or ENABLE a primary structure (database) or substructure (area, table, element), CA Datacom Datadictionary also disables or enables its substructures. When you DISABLE or ENABLE a secondary structure (dataview), CA Datacom Datadictionary does not disable or enable its substructures.
