show capture
Use the show capture command to view statistics for the Capture process.
Basic Command
The basic show capture command shows an overview of the process, such as the datasource, whether the process is running or stopped, and other basic information.
Detailed statistics
To view detailed statistics for the Capture process, use the show capture command with the [detail] option. That option shows detailed statistics that can help you assess the performance of the process, decide whether tuning parameters need to be adjusted, and detect problems or bottlenecks.
Detailed statistics for Oracle Capture
| Host |
The name of the local machine (source system). |
| System time |
The current time according to the system clock. |
| Source |
The name of the source Oracle instance. |
| Status |
The status of the Capture process (running or stopped). |
| Since |
The time that Capture started. |
| Oracle current redo log |
The sequence number of the redo log to which Oracle is writing. |
| Capture current redo log |
The sequence number of the redo log that Capture is reading. |
| Capture log offset |
The location in the redo log of the record being processed by Capture. |
| Last redo record processed |
The record being processed by Capture or the last one processed if Capture is not currently replicating data. |
| Capture state |
The state of the process, in relation to the replication work it performs: It can be one of the following:
- INITIALIZING: Capture is starting up.
- WAITING: Capture is reading the redo log and waiting for records that need to be replicated.
- WAITING FOR LOGFILE: Capture is configured to wait and then try again if it cannot access the required log.
- PROCESSING: Capture is processing a redo log record for replication.
- STOPPED DUE TO MISSING ARCHIVE LOG: Capture is configured to stop when it cannot access the log that it needs.
|
| Activation ID |
The internal identifying number of the configuration activation, which identifies the associated processes and queues. |
| Error count |
The number of records that were skipped due to Oracle errors since Capture started. Data from skipped records is not reflected in the target database. |
| Operations captured |
The number of redo records that Capture successfully processed for replication since it started. |
| Transactions captured |
The number of committed Oracle transactions whose operations Capture successfully replicated since it started. |
| Concurrent sessions |
The number of Oracle sessions being processed at the same time. |
| HWM concurrent sessions |
The largest number of concurrent Oracle sessions since Capture started. |
| Checkpoints performed |
The number of checkpoints to save the state of Capture since Capture started. Frequent checkpointing generates additional overhead on the system, but infrequent checkpoints cause SharePlex to recover less quickly from a system or instance failure. By default, Capture checkpoints every 40,000 messages, but it can be adjusted with the SP_OCT_CHECKPOINT_FREQ parameter. |
| Total operations processed |
The number of all Oracle operations and SharePlex internal operations processed by Capture since it started, including records captured for replication and records for objects not in the configuration. |
| Total transactions completed |
The number of committed Oracle transactions processed by Capture since it started, including transactions captured for replication and transactions for objects not in the replication configuration. |
| Total Kbytes read |
The size in kilobytes of the data that was processed by Capture since it started. |
| Redo records in progress |
The number of records that Capture is processing. |
| Redo records processed |
The total number of redo records processed. |
| Redo records ignored |
The number of records that Capture ignored because they are not associated with objects in the configuration. |
| Redo records - last HRID |
The head row ID value for the last chained row processed by Capture. |
Note: The show capture detail output for RAC systems will vary slightly from what is described here. The information is essentially the same, but is necessarily presented differently.

The following is displayed if this command is executed before Capture is up:

Capture is not yet replicating the most recent activation
Re-issue this command when capture’s replication is current
Show Config provides the following statistics:
For more information about the objects in the configuration, view the SID_config_log, where SID is the ORACLE_SID of the instance. SharePlex prints activation results and error messages in this file, which resides in the log sub-directory of the SharePlex variable- data directory.

show export
Use the show export command to view statistics about the Export process. This command keeps a record of the number of messages sent to target systems by all Export processes on the local machine, as well as optional statistic about Export performance. The message count begins over again whenever Export stops and starts again.
Note: Typically, a message approximately corresponds to a SQL operation, but there can be multiple messages for one operation on a LONG or LOB column, and there could be one record for numerous operations in an array insert. A message also can be an internal SharePlex operation.
