| start_context | bool | 1 | √ | null |
|
|
Indicates whether the Instance Context should be started on Instance start. General Usage If true, indicates that the Instance Context should be started, so long as the Application Context record is also set to allow context starting. If false, the Instance Context not be started, even if the related Application Context is set to allow context starts. Data Requirements

| diag_role_created | text | 2147483647 | √ | null |
|
|
The database role which created the record. General Usage This column is system maintained and should be considered read only in normal operations. Data Requirements

|
|
| diag_timestamp_modified | timestamptz | 35,6 | √ | null |
|
|
The database server date/time when the transaction which modified the record started. This field will be the same as diag_timestamp_created for inserted records. General Usage This column is system maintained and should be considered read only in normal operations. Data Requirements

|
|
| diag_wallclock_modified | timestamptz | 35,6 | √ | null |
|
|
The database server date/time at the moment the record was actually modified. For long running transactions this time may be significantly later than the value of diag_timestamp_modified. General Usage This column is system maintained and should be considered read only in normal operations. Data Requirements

|
| diag_role_modified | text | 2147483647 | √ | null |

|
The database role which modified the record. General Usage This column is system maintained and should be considered read only in normal operations. Data Requirements
User Defined Record Supported Operations
|
|
| diag_row_version | int8 | 19 | √ | null |
|
|
The current version of the row. The value here indicates how many actual data changes have been made to the row. If an update of the row leaves all data fields the same, disregarding the updates to the diag_* columns, the row version is not updated, nor are any updates made to the other diag_* columns other than diag_update_count. General Usage This column is system maintained and should be considered read only in normal operations. Data Requirements

|
|
| diag_update_count | int8 | 19 | √ | null |
|
|
Records the number of times the record has been updated regardless as to if the update actually changed any data. In this way needless or redundant record updates can be found. This row starts at 0 and therefore may be the same as the diag_row_version - 1. General Usage This column is system maintained and should be considered read only in normal operations.
