Data Management Features

This chapter describes the database management features for managing files and records in OSC.

1. Overview

The following data management features are provided by OSC to help manage the data sets used by application programs.

2. File Control

Records in data files are managed as TSAM data sets, the OpenFrame equivalent to VSAM data sets in IBM mainframe. OSC application programs access TSAM data sets in the same way that CICS application programs access VSAM data sets; their functions are the same as well. With OSC application programs, users can search for, save, and delete the records stored in local files, as well as use function shipping to access records managed on remote application servers.

OSC application servers support three types of data sets as follows:

  • Key-sequenced data set (KSDS)

    data sets in which each record is identified by a unique key.

  • Entry-sequenced data set (ESDS)

    data sets in which each record is identified by an relative byte address (RBA).

  • Relative record data set (RRDS)

    data sets in which each record is identified by an relative record number (RRN).

  1. For more information about TSAM data sets, refer to OpenFrame TSAM Guide.

  2. For more information about function shipping for files, refer to Function Shipping.
File Control Commands

The file control commands in OSC can be classified into four general categories:

  • Searching (browsing) records

    Command Description

    ENDBR

    Indicates the end of sequential search for a specific file.

    READ

    Reads a specific record in a data set.

    READNEXT

    Reads the next record during a sequential search.

    READPREV

    Reads the previous record during a sequential search.

    RESETBR

    Resets the sequential search location.

    STARTBR

    Specifies the first record of a sequential search.

  • Adding, deleting, and modifying records

    Command Description

    DELETE

    Deletes a data set (only KSDS and RRDS are valid).

    REWRITE

    Modifies a record in the data set.

    WRITE

    Adds a record to the data set.

  • Unlocking records

    Command Description

    UNLOCK

    Unlocks a record that was locked with the READ UPDATE command.

  • File management

    Command Description

    INQUIRE FILE

    Retrieves information about a FILE resource definition.

    SET FILE

    Allows the properties of a data set to be modified.

File records are searched and read using the following two methods:

  • Direct access

    Used to read a specific record. The READ command is used.

  • Sequential access

    Used to read records sequentially. The READNEXT or READPREV commands are used to read records, and the STARTBR, RESETBR and ENDBR commands to specify the starting point, reset and end records respectively.

2.1. DELETE

Deletes a record. Records can only be deleted from the KSDS and RRDS type data sets. To specify the record to delete from a data set, either use the token value returned by the UPDATE option of a search or read command, or use the RIDFLD value.

3. Named Counter Server

The named counter server (hereafter NCS) monitors the values of named counter variables. Whenever a user requests a value from a counter, the counter value is increased by one. The NCS provides functions to set the minimum and maximum server values and the incremental value of the counter, reset a counter, and delete a counter.

The OSC application server supports two kinds of counters, COUNTER and DCOUNTER. COUNTER stores values as a 4 byte binary integer (fullword signed binary value), while DCOUNTER stores values as an 8 byte binary positive value (doubleword unsigned binary value). COUNTER and DCOUNTER are used in the same manner, but are accessed by different commands.
