By executing the status information collection command (hdsstate command), you can output status information to the standard output. This information can be used to check the target Datareplicator's status. You can collect status information only while the target Datareplicator is active.

The status information includes the utilization status of the import information queue files, reception processing information, and import processing information. For details about how to collect status information, see the hdsstate command in Chapter 7. Command Syntax.

You can collect an activity trace to obtain Datareplicator's activity status and to determine its performance. You can use an activity trace for the following purposes:

• If import processing seems slow, use the activity trace for guidance in changing system settings to maximize HiRDB performance (for example, for determining whether tuning should involve using indexes for the HiRDB table definitions, or the concurrency level could be improved by executing Datareplicator's import processing in the table-based mode).
• If an import processing editing UOC routine's performance is poor, use the activity trace to determine whether the problem is with Datareplicator or with the UOC routine.

To obtain an activity trace with the target Datareplicator, you specify the int_trc_lvl and int_trc_filesz operands in the import system definition. To obtain an activity trace for each data linkage identifier, you specify the int_trc_getl operand in the import environment definition. Use the hdstrcedit command to output an obtained activity trace.

For details about activity trace definitions, see 5.8 Import system definition and 5.9 Import environment definition; for details about the hdstrcedit command, see the hdstrcedit command in Chapter 7. Command Syntax.
