You can use the installer to update HiRDB. There are two ways to use the installer to update HiRDB.

(a) Updating after terminating HiRDB

Switches performed after terminating HiRDB are performed according to the same method described in 1.4.2 Replacing an existing version with the new version. Check the following references before you update to the HiRDB update version:

• The description and notes of 1.4 Upgrading HiRDB
• The operating procedures of 1.4.2 Replacing an existing version with the new version^#
  #: The operations in the procedure that involve the pdvrup command are not needed.
  

Also perform the following before you update to the HiRDB update version.

1. Check whether HiRDB is in online status.
   Use the pdls command to check whether all units are shown as ACTIVE. If they are, proceed to step 2. If HiRDB has already terminated, proceed to step 3.
   
2. Terminate HiRDB.
   Stop HiRDB in any shutdown mode. For a HiRDB parallel server configuration, stop all HiRDB units.
   
3. Check the status of the HiRDB unit.
   Execute the pdls -d ust command to check the status of the HiRDB unit. If the termination status is 4 (unit status is STARTING or STOPPING), HiRDB is in the process of starting or stopping. After processing has finished, execute the pdls -d ust command again.
   For a HiRDB parallel server configuration, execute the pdls -d ust command on all HiRDB units and check the HiRDB unit status.
   
4. Release library sharing.
   Perform (6) Releasing library sharing described in 1.4.1 Before upgrading.
   
5. Stop commands, utilities, applications, and HiRDB-linked programs.
   Follow the instructions in (7) Stopping commands, utilities, applications, and HiRDB-linked programs in the subsection 1.4.1 Before upgrading.
   

(b) Updating with HiRDB operating

See 1.5.2 Prerequisites and following sections.
