Using External Security for CA Datacom › Setting Up Resource Classes › Table Classes

Table Classes

The table classes identify CA Datacom/DB tables and multiple access levels for each table. The valid table classes are:

• DCTABLE
• DFTABLE
• DGTABLE
• DHTABLE
• DPTABLE
• DQTABLE
• DRTABLE
• DSTABLE
• DTTABLE
• DXTABLE

The MUF recognizes ten possible access paths. Ten table classes therefore exist. Because each class has no intrinsic meaning, you can mix and match which classes are used for which paths, using each of the ten table classes for each unique path or assigning multiple paths to the same class. The SECURITY Multi-User startup option combined with the resource names defined to the DTSYSTEM resource class determines which class to use for which paths. The external security product handles the task of tying users to tables and access levels. The access levels correspond to the following CA Datacom/DB access rights:

• ADD
• DELETE
• READ
• UPDATE

Note: CA Top Secret z/OS allows READ access if UPDATE access is specified. RACF treats access levels in a hierarchical way. For more information, see Security Interfaces, RACF.

The table class resources consist of system, database, and table identifiers in the following format:

cxxname.DB0nnnn.table

For example, DBMUF001.DB00140.PAY identifies the PAY table in the database with DBID 140 in the system DBMUF001.
