Installing Cisco IOS for S/390 Release 2.0

Verify that the Linkage Editor/Binder attributes for the CSI include NCAL, LET, and SIZE=(660000,160000). If you are using the linkage editor you must remove the NCAL, LET, and SIZE parameters from the ALLOCSMP JCL. You must also change your maximum return code to a 4.

For users running MVS/ESA 4.3 or above, Binder is now supported. To use the Linkage Editor, update the options entry for IEWL to point to HEWLF064. In Cisco IOS for S/390 release 2.0 the default is to use HEWLH096, which invokes the Binder.

Cisco IOS for S/390 release 2.0 must be installed into a new CSI; you cannot use a shared CSI. Data set allocation changes in this release will cause attempts to install over an existing release to fail.

Edit the ALLOCSMP member by entering TCPNAMES at the command line.

Submit ALLOCSMP.

4ALLOCT00

Member ALLOCT00 in the CNTL library allocates the libraries that will contain the Cisco IOS for S/390 base product.

Before submitting the ALLOCT00 member, consider the following:

ALLOCT00 requires 2333 tracks. You may choose to distribute some of the libraries across multiple volumes. This requires manual editing of ALLOCT00 after you execute

TCPNAMES.

The PFSLOAD and FTPLOAD libraries are allocated. The PFSLOAD library is used with OpenEdition and contains Physical File System (PFS) modules. It must be APF-authorized. If you are not using OpenEdition, the library is not required. The FTPLOAD library will contain the FTP3 load module for IBM-FTP client compatibility.

Edit the ALLOCT00 member by entering TCPNAMES at the command line.

Submit ALLOCT00.

5INSTSMPE

Member INSTSMPE in the CNTL library is used to install the base product. Before submitting the INSTSMPE member, consider the following:

The Cisco IOS for S/390 release 2.0 product consists of four FMIDs. You must apply the Cisco IOS for S/390 FMID, T01T520, and the translate table FMID, T01X520. Optional FMIDs are the development FMID, T01D520, and the SAS 6.0 runtime FMID, SAS0600. No user changes are required.

You may submit only the RECEIVE portion of this job first. This will let you review the HOLDDATA, especially any hold action that may appear, and take appropriate action. It will also let you add additional BYPASS HOLD keywords to your APPLY statement.

Edit the INSTSMPE member by entering TCPNAMES at the command line.

If you are using a tape management system such as CA1, you must modify the label parameter on your DD statements to include EXPDT=98000.

LABEL=1,NL,,EXPDT=98000

If you are using JES3, replace the JOBPARM card with the following:

//*MAIN LINES=(999,W)

Submit INSTSMPE.
