Note 1
This table assumes that all events are processed normally. The status of a system journal file group is managed only while the journal service is operating. The status of a closed file group (on unload completion/wait status, overwritable/non-overwritable status) is not managed. Therefore, if the jnlunlfg or jnlchgfg command is executed on a closed file group, the status to be displayed by the jnlls command will not change. The status of the current files can be displayed by executing the jnlopnfg and jnlls commands after executing the jnlunlfg or jnlchgfg command.
Note 2
For the events Swap due to no space remaining in current file group, Swap due to error with current file group, and Swap with jnlswpfg, the system journal files whose status changes from Current are the swapped-out files. The system journal files whose status changes from Standby are the swapped-in files.
