4.3.2 When there are no overwrite enabled files

Overwriting of a reserved file must be enabled by means of one of the methods described below. If there are no reserved files, you must add synchronization point dump files. For details, see 4.3.5 Adding a new synchronization point dump file.

Organization of this subsection
(1) When there is a synchronization point dump file entity
(2) When there is no synchronization point dump file entity

(1) When there is a synchronization point dump file entity

There is a synchronization point dump file entity when a synchronization point dump file has been created by the pdloginit command.

Procedure
  1. Use the pdlogls command to check the reserved files.
    pdlogls -d spd -s b001
  2. Use the pdlogopen command to enable overwriting of a reserved file that has an entity.
    pdlogopen -d spd -s b001 -g syncfg01
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.

(2) When there is no synchronization point dump file entity

There is no synchronization point dump file entity when a file group name has been specified in the pdlogadfg operand but no synchronization point dump file has been created by specifying the pdloginit command.

Procedure
  1. Use the pdlogls command to check the reserved files.
    pdlogls -d spd -s b001
  2. Use the pdloginit command to create a synchronization point dump file. Assign to the created synchronization point dump file a synchronization point dump file name specified in the HiRDB system definition.
    pdloginit -d spd -s b001 -f /sysfile01/sync01 -n 5000
  3. Use the pdlogadpf command to associate the synchronization point dump file created in step 2 with the file group specified by the pdlogadfg operand.
    pdlogadpf -d spd -s b001 -g syncfg01 -a /sysfile01/sync01
  4. Use the pdlogopen command to enable overwriting of the synchronization point dump file created in step 2.
    pdlogopen -d spd -s b001 -g syncfg01
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.
