## Installing and configuring Remote DL/I

Remote DL/I requires software that runs on the workstation and on the host (MVS or OS/390). The software communicates between the platforms using APPC. The following installation and configuration tasks are required:

On the workstation you need to:

- Install the Remote DL/I component.
  code can communicate with MVS APPC.

On the host you need to:

- Install the Remote DL/I software provided with IMS.
- Configure VTAM (and possibly NCP) so that APPC communications can be used between the workstation and MVS.
- Define an APPC TP profile. In the APPC TP profile, you must specify the JCL used to bring up the Remote DL/I server program. In the JCL, you must specify the DD statements required to bring up an IMS batch environment. In addition, DD statements for the IMS databases being used can be specified. See Figure 1 for an example of the JCL used in a TP profile for Remote DL/I.

  One or more TP profiles can be set up depending on how the Remote DL/I is going to be used. For example:

  - Each COBOL programmer within a customer's organization uses the same TP profile. The COBOL programmer can specify which databases, PSB libraries, and DBD libraries to use in the Remote DL/I Server Environment File.

    For details on the Server Environment File, see the VisualAge COBOL Programming Guide.

  - Each COBOL programmer within a customer's organization may have a Remote DL/I TP profile which they can modify as needed while developing and testing applications on the workstation.

### Installation verification

Note: Once you have completed the installation and configuration activities, you can use the DLICHECK command and DLICHKP command to verify your installation. These commands are documented in the VisualAge COBOL Programming Guide.
