Configuring the post-implementation script

BMC AMI Enterprise Connector for Venafi supports a post-implementation script that you can use to perform site-specific tasks after the successful creation of a certificate, for example:

  • Issuing a command to refresh a started task running on the system
  • Running a Write to Operator (WTO) macro that your site's automation product can pick up

The post-implementation script is a REXX exec.

Configuring-after-installation

You configure the post-implementation script by copying a sample script provided with EC for Venafi, and by specifying the script name in Venafi Trust Protection Platform (TPP). For an example of a post-implementation script, see Sample post-implementation script.

The sample script is included in the RSSSAMP library, which is installed with the application. For more information, see "Installation tasks" in Installing.

To configure the post-implementation script

  1. From the SAMPLIB library installed with EC for Venafi, copy the POSTIMPL sample script.
  2. Modify the functions, arguments, and variables according to the needs of your organization. For details, see Scripting requirements and variables.
  3. Save the script. You can rename the script. If so, use that name to specify the script in TPP, as described in step 5.
  4. Copy the script to the PDS library specified in your agent's started task ECIREXX JCL statement.
  5. Specify the script in TPP as follows. For detailed instructions on working with application objects, see the TPP documentation.
    1. Navigate to the application object associated with the certificate for which you want to run the post-implementation script.
    2. In the Post-implementation script name field, specify the name of the script.
    3. (Optional) Add any additional arguments to pass to the script at runtime.
    4. Click Save.

Important

Where particular values for TPP object fields are not specified in this procedure, you can leave their defaults or set them according to your own needs. If settings given in this section conflict with your own policies, contact BMC Support for more information.

Scripting requirements and variables

For instructions on using REXX language, see the IBM documentation.

The post-implementation script is subject to the following requirements:

  • To retrieve the entry variables, the script must start with a call to the ecentry() function and it must return with a call to the ecreturn() function.
  • To write messages to the EC for Venafi log file, you must use the rsvxlog() function, which requires the following parameters:
    • The value that appears in the left-hand column of the log entry
    • The value that appears in the right-hand column of the log entry
  • To run a WTO, you must use the rsvxwto() function.

You can use the following variables after the ecentry() call.
