The HiRDB file system area (RDAREAs) table stores performance information collected over a given time period on a HiRDB file system area for RDAREAs. One line is created for each combination of a HiRDB file system area and an RDAREA.

Notes on collecting performance information

• Performance information is collected while HiRDB statistical information is being collected.
  Trigger for starting statistical information collection
  When the pdstbegin command is executed with fil specified for the statistical information type (-k option) while HiRDB is running
  When HiRDB is started by the pdstbegin operand with fil specified for the statistical information type (-k option)
  Trigger for terminating statistical information collection
  When the pdstend command is executed while HiRDB is running
  When HiRDB is terminated
  
• For a shared RDAREA, performance information is collected for each server on a separate line.
• Performance information cannot be collected on a unit that is stopped.

The following table shows the configuration of the HiRDB file system area (RDAREAs) table.

Note: Information in parentheses following pdstedit is the edit item in the statistics analysis utility.

#1: Operations are separated into groups based on the combination of RDAREA NAME and HiRDB file system area name obtained by removing the HiRDB file name from HOST, SERVER, and FILE NAME in fil_DAT in order to compute the total of the numeric value data in the fields. Overflow is indicated when ********** is output instead of numeric data, and 0 is set.

#2: Created by removing the HiRDB file name from the full-path HiRDB file name. For example, /users/hirdb_s/area/rdsys04 is obtained from /users/hirdb_s/area/rdsys04/rddata01.
