Description
Enables date/time stamp processing when set to 1. As a system manager, you can reset DTS to zero to disable automatic date/time stamps. When DTS is zero, 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.
- When DTS is reset to 0, any open files with the FOPT parameter X'10' bit on must have been opened with file manager privileges.
- If the value of the DTS parameter is 0 on a thread, subsequent opens of FOPT X'10' files must obtain file manager privileges.
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 DTS is 0, your user thread does no date/time stamp processing on any file. To turn DTS processing off for a file, you must stop the file and turn off the FOPT X'10' bit. This suspends date/time stamp processing for this file for all users.
Currently, there is no feature that can suspend date/time processing for some files for some users.
- DTS is not supported under Parallel Query Option. If you attempt a remote open of a data/time stamp file (FOPT X'10' included), the following message is issued:
