Retrieve Journal Receiver Information (QjoRtvJrnReceiverInformation) API

The Retrieve Journal Receiver Information (QjoRtvJrnReceiverInformation) API provides access to journal-receiver-related information to help manage a journal environment, including a remote journal environment.

Various types of journal receiver information are provided by the API, similar to information reported using the Display Journal Receiver Attributes (DSPJRNRCVA) CL command.

These are required only if the journal receiver has ever been associated with a journal, and that journal is on the system.

Required Parameter Group

Receiver variable

OUTPUT; CHAR(*)

The receiver variable that is to receive the information requested. You can specify the size of the area smaller than the format requested as long as you specify the length of receiver variable parameter correctly. As a result, the API returns only the data the area can hold.

Length of receiver variable

INPUT; BINARY(4)

The length of the receiver variable provided. The length of receiver variable parameter may be specified up to the size of the receiver variable specified in the user program. If the length of receiver variable parameter specified is larger than the allocated size of the receiver variable specified in the user program, the results are not predictable. The minimum length is 8 bytes.

Qualified journal receiver name

INPUT; CHAR(20)

The name of the journal receiver and its library from which the journal receiver attributes and information is to be retrieved. The first 10 characters contain the journal receiver name, and the second 10 characters contain the library name. The special values supported for the library name follow:

*LIBL	Library list
*CURLIB	Current library

Format name

INPUT; CHAR(8)

The format RRCV0100 is the only supported format that is used by this API. For more information, see RRCV0100 Format.

Omissible Parameter

Error code

I/O; CHAR(*)

The structure in which to return error information. For the format of the structure, see Error Code Parameter. If this parameter is omitted, diagnostic and escape messages are issued to the application.

RRCV0100 Format

The structure of the information returned is determined by the specified format name. For detailed descriptions of the fields, see Field Descriptions.

This system name is determined when the remote journal is activated by using the Change Remote Journal (CHGRMTJRN) command or by calling the Change Journal State (QjoChangeJournalState) API, and is based on the current system name at that time as seen by using the Display Network Attributes (DSPNETA) command.

This field is blank if there is no source journal.

Status. The status of the journal receiver. The status can be one of the following:

Text. The text description of the journal receiver.

Threshold. An auxiliary disk storage space threshold value (in kilobytes) for the journal receiver. If the threshold value is exceeded during journaling and the journal has the MNGRCV(*USER) attribute, a message (CPF7099) is sent to the message queue that is specified on the Create Journal (CRTJRN) or the Change Journal (CHGJRN) command. If the journal has the MNGRCV(*SYSTEM) attribute, the system creates and attaches a new journal receiver, detaches the old journal receiver when the threshold is reached, and sends message CPF7020 to the journal message queue. This option is applicable only for local journals and is zero for remote journals.
