This section describes z/OS® data sets that you need to define or modify for z/OS V2R1 Communications Server. Table 1 shows the z/OS data sets that contain information for z/OS V2R1 Communications Server, and Table 2 shows the z/OS data sets that contain information for both VTAM and NCP.

Name of data set | Contents | Comments |
---|---|---|
SYS1.ASAMPLIB | Sample of network operator command table and sample JCL for installation | Required for installation. Provided by IBM®. |
SYS1.SAMPLIB | Alterable copy of sample network operator command table, sample JCL for installation, and command lists for dynamic I/O | Required for installation. Provided by IBM. |
SYS1.SSPLIB | NCP loader utility program | Required; added when NCP is installed. See SYS1.SSPLIB for information on SYS1.SSPLIB requirements. |
