System log files are swapped in order to physically separate the system logs required for database restoration. To restore the RDAREAs from the backup copy to be created in step (2), the system log collected subsequently (the system log in the file to be used as the current file after swapping) will be used as input information.

 
pdlogswap -d sys -s bes1 -w
pdlogswap -d sys -s bes2 -w
 

 
pdcopy -m /rdarea/mast/mast01 -M r -u UNT1 -b /pdcopy/backup01
-p /pdcopy/list01
 

Explanation

-m: Specifies the name of the first HiRDB file in the master directory RDAREA.

-M: Specifies the referencing-permitted mode as the backup acquisition mode.

-u: Specifies that all RDAREAs under the unit (UNT1) are to be backed up.

-b: Specifies the name of the backup file.

-p: Specifies the output file name for the pdcopy command's processing results listing.

Remarks

When the automatic log unloading facility is being used, execute the pdlogatul command to record the unload log file name that corresponds to the current system log file when backup is being made.

We recommend that after the command has executed you check whether the execution results are correct. For details on how to check command execution results, see the manual HiRDB Version 9 Command Reference.
