Title

Purpose

The inactive nametab table consists of two tables, DDXTT and DDXTF.

Apparently for performance reasons, both were created as transparent tables in the database, but each with a RAW field for the crucial Nametab headers and the field data. To read the inactive Nametab table, structures X030L and X031L were used as a template. The data was then read using field symbols.

To Unicode-enable all programs that read or write to the inactive nametab table, the field symbol-based access had to be modified.

Since this meant editing all programs using DDXTT/DDXTF and since there have long since been requests to be able to read (or change) the inactive nametab data directly in the database or analyze the data using transaction SE16, we decided to replace the RAW fields in both tables with explicit fields.

This requires that the inactive nametab table is not used except for upgrades, that is, that the table is empty at all times or does only contain editable entries which can be reproduced.

Sending the table in the 'normal' way is not possible, since DDXTT/DDXTF are used for the upgrade itself. During the upgrade, a conversion would then be requested for both tables, and both would be accessed. In this case, the system would terminate.

This XPRA uses the inactive activation of DDXTT/DDXTF during an upgrade (both are saved as LIMU TABD with a modified structure). The XPRA regenerates the active nametab table from the active sources and performs a DROP/CREATE on the database. The contents of DDXTT/DDXTF are written to a log in advance.
