Native HA queue manager status attributes

The status attributes of Native HA queue managers.

[UNIX, Linux, Windows, IBM i]

The following table lists the status attributes of Native HA queue managers, and gives the equivalent MQSC parameter for the DISPLAY QMSTATUS command. For more information about MQSC commands, see Administering IBM® MQ using MQSC commands in IBM Documentation. Other status attributes applicable to the queue manager are described in Queue manager status attributes.

Table 1. Native HA queue manager status attributes
Attribute Meaning MQSC parameter
Backlog How many KB of recovery log data the active instance in a Native HA configuration has written that have not yet been acknowledged by the named instance. For replica instances, this is how 'out of sync' the named instance currently is.

[MQ 9.4.2 Feb 2025]Native HA group backlog. Only for Recovery or Pending live groups in a Native HA cross-region replication configuration.

BACKLOG
Active connections Whether the instance in a Native HA configuration currently has a pair of active connections to the active instance. CONNACTV

[MQ 9.4.2 Feb 2025]Group connections

Indicates whether the group is connected to a live or pending recovery group. Only applies to recovery, pending live, or unknown groups in a Native HA cross-region replication configuration. Set to one of the following values:
Yes
The group is connected.
No
The group is disconnected.
Unknown
The connection status is unknown.
CONNGRP

[MQ 9.4.2 Feb 2025]Group IP address

Indicates the operational status of this group and is one of the following values:
Normal
The group is operating normally.
Checking
The group is being checked to ensure the consistency of the recovery log.
Synchronizing
The group is being sent data to bring it in sync.
Rebasing
The group is being sent data a new recovery log.
Disk full
The group has a full disk.
Disconnected
Cannot communicate with the group.
Partitioned
Two groups believe they are the Live group (that is, a 'split brain' status).
Unknown
The group status is unknown.
GRSTATUS

[MQ 9.4.2 Feb 2025]Group leader version

Indicates the version of the current group leader. GRPVER
Group initial date The date of the last log record recovered when the Native HA group initially became active. HAINITDA
Group initial LSN The log sequence number (LSN) of the last log record recovered when the Native HA group initially became active. HAINITL
Group initial time The time of the last log record recovered when the Native HA group initially became active. HAINITTI

[MQ 9.4.2 Feb 2025]Initial live LSN

The log sequence number (LSN) of the last log record recovered when the Native HA group initially became live, in the formatnnnnn:nnnnn:nnnnn:nnnnn.

Only for live or pending recovery groups in a Native HA cross-region replication configuration.

INITLSN
Native HA instance name The name of the local Native HA instance when the queue manager is part of a Native HA group. INSTANCE
In-sync Whether this instance is currently considered in-sync with the active instance in a Native HA configuration. (for replica instances).

[MQ 9.4.2 Feb 2025]Indicates whether the group could become Live with no loss of data if a failover occurred. Only for recovery or pending live groups in a Native HA cross-region replication configuration.

INSYNC

[MQ 9.4.2 Feb 2025]Time of last log record

The time of the last log record recovered when the Native HA group initially became live, in ISO 8601 format. Only for live or pending recovery groups in a Native HA cross-region replication configuration. INITTIME

[MQ 9.4.2 Feb 2025]Time group became live

The time the group first became the live group, in ISO 8601 format. Only for live or pending recovery groups in a Native HA cross-region replication configuration. LIVETIME

[MQ 9.4.2 Feb 2025]Information type

Native HA information type. Can be one of the following values:
INSTANCE
Display information about instances in the local group.
GROUP
Display information about groups.
ALL
Display all information.
NHATYPE

[MQ 9.4.2 Feb 2025]Recovery LSN

A log sequence number (LSN) that the group could recover to. Given in the format nnnnn:nnnnn:nnnnn:nnnnn. RCOVLSN

[MQ 9.4.2 Feb 2025]Recovery time

A time that the group could recover to, in ISO 8601 format. RCOVTIME
Replication address The network address and port to use when sending data to and from the specified instance in a Native HA configuration. REPLADDR
Role The current role of the instance in the Native HA group. Can be ACTIVE, REPLICA, or UNKNOWN. ROLE

[MQ 9.4.2 Feb 2025]Time last in-sync

Indicates the time when this group was last in-sync with the Live group, in ISO 8601 format. Only for Recovery or Pending live groups in a Native HA cross-region replication configuration. SYNCTIME
