Logic Flow to Create and Populate a VSAM Data Set from a Sequential File

On the Linux, UNIX or Windows platforms the data file names and source member names typically have file extensions. When uploaded to the mainframe from the PC the file extension is dropped.

This suite of programs, data sets and documentation are available in a single zipped file referred to as a zPack. For additional information refer to the Downloads and Links to Similar Pages section of this document.


We have made a significant effort to ensure the documents and software technologies are correct and accurate. We reserve the right to make changes without notice at any time. The function delivered in this version is based upon the enhancement requests from a specific group of users. The intent is to provide changes as the need arises and in a timeframe that is dependent upon the availability of resources.

Table of Contents Previous Section Next Section Create and Populate a QSAM File

Many of the sample programs access a QSAM or sequential file. This file is created by running an MVS batch job using a single mainframe JCL member.

             
QSMCRTJ1

IEFBR14

EOJ

Note-1: rseq = a Record Sequential File, this example uses 80-byte, fixed length records.
Job Flow to Create a Sequential File

The first step in the job executes IEFBR14 with a DD statement that has a DISP=(MOD,DELETE,DELETE). This step will delete a previously created file with the same name.

The second step in the job executes IEBGENER. The data for populating the QSAM file is contained within the JCL member. The inline data will add 26 records to the file in alphabetic sequence by customer number.

The following is the JCL member QSMCRTJ1.jcl used to create and populate the Sequential file.

Table of Contents Previous Section Next Section Delete a VSAM, KSDS Data Set

This section describes how to delete a VSAM Keyed-Sequential-Data-Set (KSDS). A VSAM, KSDS may be date-protected. The DEFINE Cluster has the option of specifying a retention date. If this retention date has not expired then the PURGE option will be required in order to delete the data set. The default is NOPURGE.

The standard operation by the VSAM DELETE is to delete the catalog entry of the cluster and mark the space used by the cluster as reclaimable. The data contents of the cluster is no longer generally available but the data is still present until the area is reused. This introduces a potential problem or security exposure for sensitive data. The information could be retrieved using some special class of DUMP/RESTORE utilities that are often used by data center staff. The ERASE function will write over the data area used by the cluster and the original data is destroyed. The default is NOERASE.

The following JCL (KSDDELJ1.jcl) uses IDCAMS to delete a VSAM Data Set.

Table of Contents Previous Section Next Section Company Overview

SimoTime Technologies was founded in 1987 and is a privately owned company. We specialize in the creation and deployment of business applications using new or existing technologies and services. We have a team of individuals that understand the broad range of technologies being used in today's environments. Our customers include small businesses using Internet technologies to corporations using very large mainframe systems.

Quite often, to reach larger markets or provide a higher level of service to existing customers it requires the newer Internet technologies to work in a complementary manner with existing corporate mainframe systems. We specialize in preparing applications and the associated data that are currently residing on a single platform to be distributed across a variety of platforms.

Preparing the application programs will require the transfer of source members that will be compiled and deployed on the target platform. The data will need to be transferred between the systems and may need to be converted and validated at various stages within the process. SimoTime has the technology, services and experience to assist in the application and data management tasks involved with doing business in a multi-system environment.

Whether you want to use the Internet to expand into new market segments or as a delivery vehicle for existing business functions simply give us a call or check the web site at http://www.simotime.com
