Zowe Launcher

This is a POC project with the goal to provide an advanced launcher for Zowe components.

Current features

• Stopping Zowe using the conventional P operator command
• Ability to handle modify commands
• Stopping and starting specific Zowe components without restarting the entire Zowe

Future features

• Issuing WTOs indicating the start and termination of specific components (this should simplify the integration with z/OS automation)
• Passing modify commands to Zowe components
• Clean termination of the components in case if the launcher gets cancelled

Building

cd zowe-launcher
make

The launcher binary will be saved into the bin directory.

Prerequisites

• Zowe 1.11.0

Deployment

• Specify the Zowe installation and instance directories in zowe.conf
• Run patch-zowe.sh to apply the require Zowe changes
• Copy the launcher JCL (samplib/zlaunch) to your PROCLIB
• Edit the JCL and specify the launcher directory in the WORKDIR variable

Component configuration

Edit components.conf to add and remove components. The configuration consists of key-value pairs, where a key is a component name and a value is the path to the component binary.

Operating the launcher

• To start the launcher use the S operator command:

S ZLAUNCH

• To stop use the P operator command:

P ZLAUNCH

• To stop a specific component use the following modify command:

F ZLAUNCH,APPL=STOP(component_name)

• To start a specific component use the following modify command:

F ZLAUNCH,APPL=START(component_name)

• To list the components use the following modify command:

F ZLAUNCH,APPL=DISP

The project should fix the following issues
