- For V4.2.x, this view was introduced in V4.2.2.
Purpose
The GV$OB_SYS_TIME_MODEL view displays the Time Model statistics at the tenant level in a cluster.
Columns
| Column | Type | Nullable? | Description |
|---|---|---|---|
| TENANT_ID | NUMBER | NO | Tenant ID |
| SVR_IP | VARCHAR2(46) | NO | Node IP |
| SVR_PORT | NUMBER(38) | NO | Node port |
| STAT_ID | NUMBER | NO | Stat ID |
| STAT_NAME | VARCHAR2(64) | NO | Stat name |
| VALUE | NUMBER | NO | Stat value |
The following table describes the statistics events in the STAT_NAME column and their corresponding IDs.
| Statistic event name | Description | Statistic event ID | Statistic event type |
|---|---|---|---|
| DB time | Total time of database activity, which is the sum of CPU time and non-idle wait time. | 200001 | 3072 |
| DB CPU | CPU time of database activity. | 200002 | 3072 |
| background elapsed time | Total execution time of background processes. | 200005 | 3072 |
| background cpu time | CPU time consumed by background processes. | 200006 | 3072 |
| non idle wait time | Total time of non-idle wait. This is the total time when sessions are in a waiting state but not in an idle wait state. | 200010 | 3072 |
| idle wait time | Total time of idle wait. This is the total time when sessions are in an idle wait state. | 200011 | 3072 |
| background database time | Total time of database operations executed by background processes. | 200012 | 3072 |
| background database non-idle wait time | Total time of database operations executed by background processes in a non-idle wait state. | 200013 | 3072 |
| background database idle wait time | Total time of database operations executed by background processes in an idle wait state. | 200014 | 3072 |
| concurrency wait total time | Total wait time due to concurrency issues, such as wait time due to resource lock. | 220001 | 3072 |
| user io wait total time | Total wait time of user processes for I/O operations, such as reading data or writing data to disk. | 220002 | 3072 |
| application wait total time | Total wait time generated by user application code, such as wait time due to row-level locking or explicit locking commands. | 2200013 | 3072 |
Sample query
obclient [SYS]> SELECT * FROM SYS.GV$OB_SYS_TIME_MODEL;
