Description
Enables date/time stamp processing when set to 1. System managers can reset DTS to 0 to disable automatic date/time stamps. When DTS is 0, if you have file manager privileges, you can update a DTSFN field with values of your choosing.
| Value | Behavior |
|---|---|
| 1 | For date/time stamp files, transactions participate in DTS updating. The date/time stamp field of an updated record is automatically updated at the beginning of COMMIT processing.
This is the default setting for the parameter. |
| 0 | Transactions do not participate in DTS updating. When a transaction does not participate in DTS processing, the date/time stamp field will not be updated on records that are themselves updated. |
- You must be a system manager to reset the DTS parameter. You can reset DTS for your thread only.
If DTS=0 is set in the CCAIN for the Online, it will be ignored and DTS=1 will be assumed, and a warning message will be written to the audit trail. - When you are resetting DTS to 0, any open files with the FOPT parameter X'10' bit on must have been opened with file manager privileges, or the RESET DTS will fail.
- If the value of the DTS parameter is 0 on a thread, subsequent opens of FOPT X'10' files must obtain file manager privileges, or the OPEN FILE filename will fail.
Note: During FLOD/FILELOAD, the DTS field, if one is defined to the file, is not updated. This means that a new DTS field defined as part of a file reorganization will not have a value calculated during the reorganization. Existing DTS fields are only added from TAPEI input, and they are not automatically updated by the DTS feature.
Usage
- If you reset DTS to 0 on your thread (for example, in a BATCH204 or BATCH2 job, or any Online thread), no date/time stamp processing will occur for any file accessed on this thread.
- If you have file manager privileges for a date/time stamp file, you can turn DTS processing off by stopping the file and resetting FOPT to turn off the X'10' bit. This suspends date/time stamp processing for this file for all users.
Currently, the DTS parameter cannot suspend automatic date/time stamp processing for all files in an Online; that is, the DTS=1 default of the Online cannot be SET or RESET to DTS=0.
- DTS is not supported under Parallel Query Option. Any attempt to open a remote date/time stamp file (FOPT X'10') will fail.
