Specify the application name in supported programming languages

Before Version 9.2.0, you could already specify an application name on Java or JMS client applications. From Version 9.2.0 this feature is extended to other programming languages on IBM MQ for Multiplatforms.

How the application name is used

The application name is output from:

runmqsc DISPLAY CONN APPLTAG
runmqsc DISPLAY QSTATUS TYPE(HANDLE) APPLTAG
runmqsc DISPLAY CHSTATUS RAPPLTAG
MQMD.PutApplName
Application activity trace

The application name is also used when configuring application activity trace. The default application name for non-Java applications is the truncated name of the executable, except on Windows and IBM i.

On Windows, the default name is the fully qualified executable name, truncated to 28 characters on the left.

On IBM i, the default name is the job name.

For Java applications it is the class name prefixed by the package name truncated on the left to 28 characters.

For more information, see PutApplName.

From Version 9.2.0, applications on IBM MQ for Multiplatforms can set their application names either administratively or by using various programming methods. This enables applications to provide a more meaningful platform-independent name, when you configure application activity trace or when output from various runmqsc commands.

From Version 9.2.0, we can rebalance applications across a uniform cluster. Meaningful application names are used to achieve this.

Supported characters

See Recommended application name characters for more information on how you specify the application name.

Programming languages

See Programming language connections for more information on how applications resolving to the IBM MQ libraries in C, and other programming languages, can provide the application name.

Managed .NET applications

See Managed .NET applications for information on how managed .NET applications can provide the application name.

XMS applications

See XMS applications for information on how XMS applications can provide the application name.

Java and JMS bindings applications

See Java and JMS bindings applications for information on how Java and JMS applications can provide the application name.
