Use this command to change the attributes of a data store (DS) or to change
the attributes of a data definition (DD) for a specific data store.
Requirements and Restrictions
- You must initialize TPF collection support (TPFCS) and define
the target data store before you enter this command.
- The TPF system must have get file storage (GFS) pools enabled
before you can use this message. Pools are not enabled until the system
is cycled to CRAS state or above.
Format
- DS
- changes a data store.
- dsname
- is the 1- to 8-character name of the data store.
- DD
- changes a data definition.
- ddname
- is the 1- to 32-character name of the data definition.
- INVENTORY
- specifies that a collection inventory will be maintained for this data
store. If no collection inventory exists, it will be created.
- Note:
- Only persistent identifiers (PIDs) for collections that are created after the
inventory has been created will be added to the inventory.
- NOINVENTORY
- specifies that no collection inventory will be used for this data
store. If there is a collection inventory, it will be deleted.
- DELETE
- determines the disposition of deleted collections, where:
- DELAY
- specifies that a deleted collection will be added to the DS_DELETED data
store system collection and will not be deleted from the system for 48
hours. The collection can be reclaimed during the 48-hour
interval. All pending deletes can be processed by entering ZBROW COL
EMPTY DS_DELETED.
- IMMED
- specifies that a deleted collection will be immediately returned to the
system and cannot be reclaimed. If there are deletions pending, they
are processed immediately.
- NOSHADOW
- specifies that no shadowing will be used for this collection.
- SHADOW
- specifies the use of shadowing for this collection.
- DATARID
- defines the record ID for the data records.
- DIRECTRID
- defines the record ID for the directory records.
- INDEXRID
- defines the record ID for the index records.
- recordid
- is a 4-character hexadecimal record ID.
- FORCE
- builds the collection using an extended structure rather than the normal
compact structure.
- NOFORCE
- builds the collection with the normal compact structure.
Additional Information
None.
Examples
The BATCHWRK data store (DS) was created with default options that caused
it to be created with an inventory and delayed deletions active. It was
determined that the inventory or the delayed deletions are not wanted and,
therefore, should be removed. In the following example, the data store
is changed to remove both functions.
