jnladdfg (Define checkpoint dump file group name and attributes)

Format

{{jnladdfg [-j srf] -g file-group-name [ONL]}}

Function

The jnladdfg command defines the file group name and attributes of a checkpoint dump file and a server recovery journal file. For a server recovery journal file not created as an OpenTP1 file, the jnladdfg or jnladdpf command with the -j option specified must not be used. Only one jnladdfg command can be specified in a definition if its -j option is specified.

Within the checkpoint dump service definition, 2 to 60 jnladdfg commands can be specified. Two to 30 jnladdfg commands can be specified if ONL of the checkpoint dump file is specified in them.

Any file group name must be unique in all checkpoint dump service definitions.

Options

-j srf~<1-8 character identifier>

To use the server recovery journal file for the system switchover configuration, you must create the server recovery journal file as an OpenTP1 file on the common disk device. At this time, be sure to specify this option.

See the description about the server recovery journal file in the manual OpenTP1 Description.

-g checkpoint-dump-file-group-name~<1-8 character identifier>

Specify the file group name of a checkpoint dump file.

ONL

Specify ONL if the applicable file group is to be opened at online startup.

If this operand is not specified, it becomes a closed reserved file group at online startup.

In the server recovery journal file definition, omitting this option makes no difference.
