If a space shortage occurs in a synchronization point dump file, the following procedure can be used during HiRDB operation to increase the synchronization point dump file size.

Procedure

1. Use the pdlogls command to check the status of the synchronization point dump files.
   pdlogls -d spd -s b001
   
2. Use the pdlogcls command to make an overwrite enabled file into a reserved file.
   pdlogcls -d spd -s b001 -g syncfg01
   
3. Use the pdlogrm command to delete the reserved file.
   pdlogrm -d spd -s b001 -f /sysfile01/sync01
   
4. Use the pdloginit command to re-create the synchronization point dump file deleted in step 3.
   Then, increase the record count to a value greater than the record count for the synchronization point dump file before the change. To decrease the file size, decrease the record count.
   pdloginit -d spd -s b001 -f /sysfile01/sync01 -n 5000
   
5. Use the pdlogopen command to enable overwriting of the synchronization point dump file created in step 4.
   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.

Note

When you change overwrite enabled files into reserved files, make sure that you do not change all overwrite enabled files into reserved files. If a synchronization point dump needs to be output while there are no overwrite enabled files, HiRDB (or the unit for a HiRDB parallel server configuration) will terminate abnormally. Therefore, it is important to leave at least one overwrite enabled file when you change the size of a synchronization point dump file.
