Command

Required Keywords

OPTION=ALTER

Requests the CXXMAINT ALTER option.

,AREA=

Identifies the data or Index Area whose data set name is to be changed.

Valid Entries:: The DATACOM-NAME of the data area, or the index area name (IXX or Inn, where nn is 00 to 99).
Default Value:: (No default)

,DBID=

Identifies the database associated with the data or Index Area.

,DSN=

Specifies the new data set name.

The DSN= cannot be set to spaces. A space serves as a delimiter and terminates the name. Do not use quotation marks to enclose the name.

Note: See restrictions on changing data set names below.

Note: The following are special considerations to be aware of.

The data set name for the base used for the CBS index can be changed only in one of the following ways:
- The enabled Multi-User Facility has a different database as the CBS index.
- The Multi-User Facility is not enabled, is not externally secured for DBUTLTY, and the DBUTLTY INIT function is used, as in the following example:
```
 DBUTLTY INIT DBID=6,AREA=IXX
 DBUTLTY INIT DBID=17,AREA=IXX
 DBUTLTY INIT DBID=17,AREA=TTM
 DBUTLTY LOAD DBID=17,FORMAT=NONE,KBYTES=9999,SORT=1
```
The data set name for the SQL temporary table management (TTM) index (IXX) or data area (TTM) may only be changed in one of the following manners:
- The enabled Multi-User Facility has a virtual TTM base.
- The enabled Multi-User Facility has SQL not generated.
- The Multi-User Facility is not enabled, is not externally secured for DBUTLTY, and the DBUTLTY INIT function is used.
A data area or index area data set cannot be shared by two CXXs. This can result in data integrity problems and index corruption.
