jnlsort (Sort and merge unload journal files or global archive unload journal files chronologically)

-n node-identifier~<4 alphanumeric characters and symbols)

Sorts and merges only the journal blocks having the specified node identifier.

The node identifier must begin with an alphabetic character, followed by alphanumeric characters. If this option is omitted, the file is not sorted and merged on a node identifier basis.

-g

Specify this option only to merge journal blocks, not to sort them.

When multiple unload journal files and global archive unload journal files are specified, the files are merged in ascending order of run ID (generation number if the files are executed during the same online operation). Note that journal blocks are not sorted. When you specify this option, work files are not created.

-i [begin-journal-server-run-ID][, end-journal-server-run-ID] ~<1-8 hexadecimal digits>((0-ffffffff))

Sorts and merges only the journal blocks having the specified journal server run ID.

If the -i option is specified, either a begin or end journal server run ID must be specified. If both are specified, the begin journal server run ID must be equal to or smaller than the end journal server run ID.

If the begin journal server run ID is omitted, the journal blocks ranging from 0 to the specified end journal server run ID are sorted and merged.

If the end journal server run ID is omitted, the journal blocks ranging from the specified begin journal server run ID to ffffffff are sorted and merged.

When this option is omitted, journal blocks are not sorted and merged on a journal server run ID basis.

file-name~<path name>

Specifies the name of an unload journal file and a global archive unload journal file. You can specify a maximum of 256 files.

When this command argument is omitted, the standard input is input. Specify this command argument when the -n option is omitted.

The combinations of options and command arguments that can be specified are shown below:

Option	-n	-g	-i	Unload journal file	Global archive unload journal file
-n	--	Y	Y	Y	Y
-g	Y	--	Y	Y	Y
-i	Y	Y	--	Y	Y
Unload journal file	Y	Y	Y	--	Y
Global archive unload journal file	Y	Y	Y	Y	--

Y: Can be specified

Message ID	Description	Output destination

The jnlsort command creates temporary work files for using the OS sort command. Following are the work files that are created by the jnlsort command:

File name Directory File size

sort_i + process ID Current directory 256 bytes x number of blocks to be sorted

sort_o + process ID Current directory 256 bytes x number of blocks to be sorted
When you specify the standard input (when you omit a file name as a command argument), only a global archive unload journal file can be entered.
The number of characters you can enter in this command is determined by your OS. If the number of entered characters exceeds the upper limit, an error occurs.
An error occurs when the number of opened files exceeds the maximum number of files that can be opened for one process, including when the specified number of files is less than 256.

File name	Directory	File size
sort_i + process ID	Current directory	256 bytes x number of blocks to be sorted
sort_o + process ID	Current directory	256 bytes x number of blocks to be sorted
