VSAM support

VSAM support for EGL-generated Java code is as follows:

• AIX-based code can access local VSAM files

• The following code can access remote VSAM files on z/OS:
  • EGL-generated Java code that runs on Windows 2000/NT/XP

  • The EGL debugger, which runs on Windows 2000/NT/XP

Access prerequisites

Access requires that you first define the VSAM file on the system where you want the file to reside. Remote access from Windows 2000/NT/XP (whether for the EGL debugger or at run time) also requires that you install Distributed File Manager (DFM) on the workstation as follows:

1. Locate the following file in your EGL installation directory:

     workbench\bin\VSAMWIN.zip

2. Unzip the file into a new directory and follow the directions in the INSTALL.README file.

System name

To access a local VSAM file, specify the system name in the resource associations part and use the naming convention that is appropriate to the operating system. To access a remote VSAM file from the EGL debugger or from EGL-generated Java code, specify the system name in the following way:

  \\machineName\qualifier.fileName

machineName

The SNA LU alias name as specified in the SNA configuration

qualifier.fileName

The VSAM data set name, including a qualifier

The naming convention is similar to the Universal Naming Convention (UNC) format. For details on UNC format, refer to the Distributed FileManager User's Guide, which is in the following file in your EGL installation directory:

  workbench\bin\VSAMWIN.zip
