Use this command to decrease the space that can be used by the recovery log.
Attention: | Do not change the size of an allocated recovery log volume after it has been defined to TSM. If you do, TSM may not initialize correctly and data could be lost. |
You can use the REDUCE LOG command while users are accessing the server. Use the QUERY LOG command to determine how much you can reduce the assigned capacity of the recovery log.
This command can generate a background process that can be canceled with the CANCEL PROCESS command. If a REDUCE LOG background process is canceled, the assigned capacity ofthe recovery log may be partially reduced. To display information on background processes, use the QUERY PROCESS command.
