Prerequisites - CONNX for VSAM / QSAM / PDS

CONNX for VSAM / QSAM / PDS requires that:

  • The target system be set up to support TCP/IP communications.

  • The TCP/IP Started Task must be running.

  • Read/write FTP access be configured and available on the target system.

  • Both the installation PC client and the target host (OS/390 z/OS) must have FTP enabled.

CONNX for VSAM / QSAM / PDS can access any VSAM, QSAM, or partitioned data set defined on the target OS/390 / z/OS system, as long as the host user ID has the necessary privileges as defined via IBM RACF (Resource Access CONTROL Facility) or a RACF-compatible product such as eTrust CA-Top Secret Security for z/OS & OS/390®. COBOL copybooks for the target files must reside in partitioned data sets defined for FTP read access.

 

Verifying TCP/IP Connectivity

 

Before you install CONNX on your VSAM server, we recommend that you verify the TCP/IP connectivity to your OS/390 z/OS system. To verify connectivity:

  1. Open a Command Prompt window.

  2. On the task bar, click Start and then click Run

  3. Type or select:

ping hostname

where hostname is the TCP/IP symbolic address or dotted numeric address.

 

A successful ping (connectivity) will generate output in the command window similar to the following:
