How the plug-in works
The plug-in executes SQL statements against a Db2 region, export a Db2 table, and call a stored procedure.
The plug-in exposes its API so that the plug-in can be used directly in other products.
Before you install and use the plug-in:
Install Zowe CLI on your computer.
Have a license file for IBM Db2 Database for z/OS.
For connectivity to Db2 for z/OS, the Db2 region should be
db2connectlicense file should be provided. Copy the
db2connectlicense file to the
[db2 plugin folder]/node_modules/ibm_db/installer/clidriver/license/folder. For more information, see Addressing the license requirement on the Zowe Docs site.
(MacOS only) Download and Install Xcode.
Use one of the following methods to install the plug-in:
Install the plug-in from an online registry or a local package.
Use the online registry/local package method when you simply want to install the plug-in to Zowe CLI and start using it.
For more information, see Installing plug-ins on the Zowe Docs website.
Build the plug-in from source and install it into your Zowe CLI implementation.
Use the build from source method when you want to install the plug-in to Zowe CLI using the most current binaries and modify the behavior of the plug-in. For example, you want to create a new command and use the plug-in with the command that you created.
For more information, see Building from source.
Building from source
Follow these steps:
The first time that you clone this plug-in from the GitHub repository, issue the following command against the local directory:
The command installs the required dependencies and several development tools. You can run the task at any time to update the tools as needed.
To build your code changes, issue the following command:
npm run build
The first time you build your code changes, you will be prompted for the location of the Imperative CLI Framework package, which is located in the
node_modules/@zowefolder in the Zowe CLI home directory.
Note: When you update
package.jsonto include new dependencies, or when you pull changes that affect
package.json, issue the
npm updatecommand to download the dependencies.
Issue one of the following commands to install the plug-in:
zowe plugins install <local path your cloned repo>
zowe plugins install .
Tip: After the installation process completes, it validates that the plug-in was installed correct and the names of its commands, options, and arguments do not conflict with that of the other plug-ins that you installed into your Zowe CLi implimentation.
When the validation process is successful, the following message displays:
Validation results for plugin 'db2': Successfully validated.
When an unsuccessful message displays, you can troubleshoot the installation by addressing the issues that the message describes. You can also review the information that is contained in the log file that is located in the Zowe CLI home directory.
Creating a user profile
After you install the plug-in, you create a Db2 profile. A Db2 profile is required to issue commands to the Db2 region. Db2 profiles contain your host, port, user name, password, and a database name for the IBM Db2 server of your choice. You can create multiple profiles and switch between them as needed.
Follow these steps:
Create a Db2 profile:
zowe profiles create db2 <profile name> -H <host> -P <port> -u <user> -p <password> -d <database>
The result of the command displays as a success or failure message. You can use your profile when you issue commands in the Db2 command group.
Tip: For more information about the syntax, actions, and options, for a profiles create command, open Zowe CLI and issue the following command:
zowe profiles create db2 -h
You can perform the following types of tests on the IBM DB2 plug-in:
For information about running automated, unit, and system and integration tests using the plug-in, see Zowe CLI Plug-in Testing Guidelines.
Before you can perform the tests, copy the file named
.../__tests__/__resources__/properties/example_properties.yaml and create a file named
Note: Information about the required values and how to customize the
custom_properties.yaml file is provided in the yaml file itself.
Issue the following commands to run the tests:
npm run test:unit
npm run test:integration
npm run test:system
Any failures potentially indicate an issue with the set-up of the Rest API or configuration parameters that were passed in the
Follow these steps:
- To uninstall the plug-in from a base application, issue the following command:
zowe plugins uninstall @zowe/db2-for-zowe-cli
After the uninstallation process completes successfully, the product no longer contains the plug-in configuration.
For information about contributing to the plug-in, see the Zowe CLI Contribution Guidelines. The guidelines contain standards and conventions for developing plug-ins for Zowe CLI. This includes information about running, writing, maintaining automated tests, developing consistent syntax in your plug-in, and ensuring that your plug-in integrates properly with Zowe CLI.
