When a server process or client has been terminated forcibly, HiRDB outputs troubleshooting information under %PDDIR%\spool. If a command or utility is terminated by pressing Ctrl + C, temporary work files output by the command or utility remain in %PDDIR%\tmp and are not deleted. These remaining troubleshooting information items and temporary work files are often the cause of a shortage of disk space available to the HiRDB directory. Because insufficient disk space for the HiRDB directory can cause abnormal termination, HiRDB deletes the following files periodically:

• Troubleshooting information files (files in %PDDIR%\spool)
• Temporary work files (files in %PDDIR%\tmp)

Normally, these files are deleted every 24 hours. The interval between deletions can be changed with the pd_spool_cleanup_interval operand. The pd_spool_cleanup_interval_level operand can be used to specify that only files that were output earlier than a specified number of days previous to the current date are to be deleted.

It is also possible to delete all at once all troubleshooting information (all files in %PDDIR%\spool).

• Use the pdcspool command to delete the troubleshooting information files. Temporary work files (in %PDDIR%\tmp) can also be deleted.
• Automatically delete the troubleshooting information files during the HiRDB startup. In this case, use the pd_spool_cleanup operand to specify whether or not to delete the troubleshooting information files. If you omit this operand, the troubleshooting information files are deleted automatically.
  You can also use the pd_spool_cleanup_level operand to delete only those troubleshooting information files that have been output a specified number of days ago.
  

Note

You can select the troubleshooting information to be deleted using the pdcspool command's option or pd_spool_cleanup_level operand.
