Format of database output files

When you direct the output of the Display Journal (DSPJRN) command to a database file, the system creates the output file records in a standard format.

The system creates the database file in one of these standard formats that are determined by the value that is specified for the OUTFILFMT parameter:

*TYPE1
*TYPE2
*TYPE3
*TYPE4
*TYPE5

Fixed-length portion of the journal entry has a complete description of these formats.

You can create an output file to hold the output from the DSPJRN command, but the format has to match the format of one of the IBM^®-supplied output files.

Processing journal entry data

There are many ways to work with the journal entry data, including the entry-specific data, depending on the command that you use to process the journal entry data.

Use your high-level language (HLL) to subdivide the fields into subfields.
Use the Retrieve Journal Entry (RTVJRNE) command and the substring built-in function.
Use the Receive Journal Entry (RCVJRNE) command and the substring built-in function.
Use the Retrieve Journal Entries (QjoRetrieveJournalEntries) API and map out the data that is returned.

Analyzing your journal activity

You can use the DSPJRN command to help analyze your journal entries. For example, you could determine how many of each type of entry (such as add or update) was done for a specific object or by a specific user.
