8.1.6 Suppressing output of information messages during utility execution
When a utility is executed, a large number of information messages indicating the processing status of the utility might sometimes be output to the terminal's standard output, syslogfile, and the message log file. This might cause the standard output screen to scroll or files to wrap around, which in turn might cause important messages to disappear.
If such a problem occurs, you can suppress output of these information messages by the utility. You can suppress information message output for the following utilities:
- Database load utility (pdload)
- Database reorganization utility (pdrorg)
- Rebalancing utility (pdrbal)
- Organization of this subsection
- (1) Specifying an information message output suppression level
- (2) Messages whose output is to be suppressed
(1) Specifying an information message output suppression level
To suppress message output by a utility, specify an information message output suppression level (lvl0, lvl1, or lvl2) for the following options when a utility is executed:
- The -m option of pdload
- The -m option of pdrorg
- The -m option of pdrbal
The following table shows option specification values and message output destinations.

- This file is created immediately under the work file output destination directory (which is specified by the pd_tmp_directory operand). If the pd_tmp_directory operand is omitted, HiRDB determines the work file output destination. For details, see the HiRDB Version 9 System Definition.
- For details about work file names, see the explanation of the -m option of each utility in the manual HiRDB Version 9 Command Reference.
Since messages are output to the work file for troubleshooting purposes (to check whether a utility is active), we recommend that you normally specify lvl1 if there is no need to check these messages.
(2) Messages whose output is to be suppressed
A utility determines which messages not to output according to the following standards:
- Numerous information messages that are output (with a message ID of -I)
- Messages indicating the start or end of processing for each transaction
- Message indicating the name of the generated work file
- Message indicating the deletion of a generated work file
- Messages that increase in proportion to the number of RDAREAs
- Messages that increase in proportion to the number of indexes
- Messages that increase in proportion to the number of servers
- Messages that have the same meaning as those messages whose output has been suppressed in step 1 (even messages that are not output in large numbers are suppressed)
