Data Sources Accessed by Classic Connect

Classic Connect provides relational read-only access to IMS databases and VSAM data sets. It creates a logical, relational database, complete with logical tables that are mapped to actual data in IMS or VSAM databases. Specifically:

  • For IMS, each logical table corresponds to one or more segments of a path in an IMS full-function database. The fields of multiple segments in a path map to the columns of a logical table. Each unique set of segment instances for the given path maps to a row in a logical table.
  • For VSAM, each logical table corresponds to a VSAM data set. Each field of the data set maps to a column of the logical table; each record of the data set maps to a row. Classic Connect can read data from VSAM KSDS, RRDS, and ESDS data sets.

Using this relational structure, Classic Connect translates relational queries into DL1 calls or VSAM reads against IMS databases and VSAM data sets respectively, and returns the result in a relational (for example, a table) format.

Multiple logical databases can be defined for a single data source (such as, a set of VSAM data sets or a single IMS database). Multiple logical tables can be defined in a logical database.

Multiple logical tables can be defined for a single data entity (such as a VSAM data set or an IMS segment). For example, a single VSAM data set can have multiple logical tables defined for it, each one mapping data in a new way.

Consists of Four Major Components

  • Client Interface Module
  • Data Server
  • Enterprise Server
  • Data Mapper

Client Interface Module: The Client Interface Module is used to establish and maintain connections with Data Servers and Enterprise Servers. It performs the following functions:

  • Determines and loads the appropriate transport layer module, based on configuration parameters
  • Establishes communications with Data Servers and Enterprise Servers
  • Stores and retrieves data in the application storage areas
  • Presents error and feedback information to the application

The Client Interface Module can establish multiple connections to a Data Server or Enterprise Server on behalf of a single application program.

The Client Interface Module is contained in both DataJoiner and the sample applications (DJXSAMP) on MVS, AIX, and Windows NT. The sample applications are used during initial setup, for testing the configuration, and for problem determination. They are also useful for designing application queries.

Data Server: All data access is performed by Data Servers. A Data Server is responsible for the following functions:

  • Accepting SQL queries from DataJoiner or the sample applications (DJXSAMP)
  • Determining the type of data to be accessed
  • Rewriting the SQL query into the native file or database access language needed; A single SQL access could translate into multiple native data requests.
  • Optimizing queries based on generic SQL query rewrite and file- or database-specific optimization
  • Querying multiple data sources for JOINs
  • Translating result sets into a consistent relational format, which involves restructuring non-relational data into columns and rows
  • Sorting result sets as needed; for example, ORDER BY
  • Issuing all client catalog queries to the Classic Connect Meta Data Catalog

A Classic Connect Data Server accepts connection requests from DataJoiner and the sample applications on AIX, Windows NT, and MVS.

Enterprise Server: This optional component manages a large number of concurrent users across multiple data sources. An Enterprise Server contains the same tasks that a Data Server uses, with the exception of the query processor and the initialization services.

Like a Data Server, the Enterprise Server's Connection Handler is responsible for responding to client connection requests. However, when a connection request is received, the Enterprise Server does not forward the request to a query processor task for processing. Instead, the connection request is forwarded to a Data Source Handler (DSH) and then to a Data Server for processing. The Enterprise Server maintains the end-to-end connection between the client application and the target Data Server. It is responsible for sending and receiving messages between the client application and the Data Server.

The Enterprise Server is also used to perform load balancing. Using configuration parameters, the Enterprise Server determines the locations of the Data Servers that it will be communicating with and whether those Data Servers are running on the same platform as the Enterprise Server.

The Enterprise Server can automatically start a local Data Server if there are no instances active. It can also start additional instances of a local Data Server when the currently active instances have reached the maximum number of concurrent users they can service, or the currently active instances are all busy.

Data Mapper: The Classic Connect non-relational Data Mapper is a Microsoft Windows™-based application that automates many of the tasks required to create logical table definitions for non-relational data structures. The objective is to view a single file or portion of a file as one or more relational tables. The mapping must be accomplished while maintaining the structural integrity of the underlying database or file.

The Data Mapper interprets existing physical data definitions that define both the content and the structure of non-relational data. The tool is designed to minimize administrative work, using a definition-by-default approach.

Additional Detailed Operations of Classic Connect

Five Types of Services that Run in the Data Server Component

  • Region controller services, which include an MTO operator interface
  • Initialization services
  • Connection handler services
  • Query processor services
  • Logger services

Region Controller Services: The primary component of a Data Server is the region controller. The region controller is responsible for starting, stopping, and monitoring all of the other components of the Data Server. These different components are referred to as services. The services are implemented as individual load modules running as separate MVS™ tasks within the Data Server address space. Services can have multiple instances, and each instance can support multiple users.

The region controller determines which services to start based on SERVICE INFO ENTRY parameter settings.

Included in the region controller service is the MVS Master Terminal Operator (MTO) interface, which allows you to display and control the services and users that are being serviced by a Data Server. Using the MTO interface, you can also dynamically configure the Data Server.

Initialization Services: Initialization services are special tasks used to initialize and terminate different types of interfaces to underlying database management systems or MVS system components. Currently, two initialization services are provided:

  • IMS™ BMP/DBB/DLI Initialization Service — Used to initialize the IMS region controller to access IMS data using a BMP/DBB interface
  • IMS DRA Initialization Service — Used to initialize the Classic Connect DRA interface and to connect to an IMS DBCTL region to access IMS data using the DRA interface

Connection Handler (CH) Services: A CH service task is responsible for listening for connection requests from DataJoiner® and the sample applications. Connection requests are routed to the appropriate query processor task for subsequent processing.

Classic Connect supplies three typical transport layer modules that can be loaded by the CH task:

  • TCP/IP
  • SNA LU 6.2
  • MVS Cross Memory Services

The MVS client application, DJXSAMP, can connect to a Data Server using any of these methods. However, the recommended approach for local clients is to use MVS Cross Memory Services. DataJoiner or DJXSAMP2 sample applications on AIX® and Windows NT® use TCP/IP or SNA to communicate with a remote Data Server.

Query Processor Services: The query processor is the component of the Data Server that is responsible for translating client SQL into database- and file-specific data access requests. The query processor treats IMS and VSAM data as a single data source and is capable of processing SQL statements that access either IMS, VSAM, or both. Multiple query processors can be used to separately control configuration parameters, such as those that affect tracing and governors, to meet the needs of individual applications.

The query processor can service SELECT statements. It invokes one or more subsystem interfaces (SSIs) to access the target database or file system referenced in an SQL request. The following SSIs are supported:

  • IMS BMP/DBB Interface — Allows IMS data to be accessed through an IMS region controller. The region controller is restricted to a single PSB for the Data Server, limiting the number of concurrent users a Data Server can handle.
  • IMS DRA Interface — Allows IMS data to be accessed using the IMS DRA interface. The DRA interface supports multiple PSBs and is the only way to support a large number of users. This is the recommended interface.
  • VSAM interface — Allows access to VSAM ESDS, KSDS or RRDS files. This interface also supports use of alternate indexes.

Classic Connect supplies a RUNSTATS utility program that is used to update population statistics for the logical tables and their associated indexes and keys. This information can be used by the query processor to optimize JOINs.

Logger Service: A logger service is a task that is used for system monitoring and trouble shooting. A single logger task can be running within a Data Server. During normal operations, you will not need to be concerned with the logger service.

Data Mapper Details: The Data Mapper accomplishes the creation of logical table definitions for non-relational data structures by creating Meta Data Grammar from existing non-relational data definitions (COBOL copybooks). The meta data grammar is used as input to the Classic Connect Meta Data Utility to create a Meta Data Catalog that defines how the non-relational data structure is mapped to an equivalent logical table. The Meta Data Catalogs are used by query processor tasks to facilitate both the access and translation of the data from the non-relational data structure into relational result sets.

The Data Mapper import utilities create initial logical tables from COBOL copybooks. A visual point-and-click environment is used to refine these initial logical tables to match site- and user-specific requirements. You can utilize the initial table definitions automatically created by Data Mapper, or customize those definitions as needed.

Multiple logical tables can be created that map to a single physical file or database. For example, a site may choose to create multiple table definitions that all map to an employee VSAM file. One table is used by department managers who need access to information about the employees in their departments; another table is used by HR managers who have access to all employee information; another table is used by HR clerks who have access to information that is not considered confidential; and still another table is used by the employees themselves who can query information about their own benefits structure. Customizing these table definitions to the needs of the user is not only beneficial to the end-user but recommended.

The Data Mapper contains embedded FTP support to facilitate file transfer from and to the mainframe.

The steps involved are:

  1. Import existing descriptions of your non-relational data into Data Mapper. COBOL copybooks and IMS-DL/I database definitions (DBDs) can be imported into the Data Mapper.
    The Data Mapper creates default logical table definitions from the COBOL copybook information. If these default table definitions are suitable for end-users, skip to 3.
  2. Refine or customize the default table definitions as needed by the users. For example, importing the record layout for the VSAM customer master file creates the default Customer_Table. Two additional tables can also be created from the original:
    • Marketing_Customer_Table, which contains only those data elements required by the marketing department
    • Service_Customer_Table, which contains only those data elements required by support representatives
  3. Generate the actual Meta Data Grammar that will be used by the Meta Data Utility on MVS.
  4. Transfer the logical table definitions to the mainframe where the database or file resides. These definitions are then used as input to the Meta Data Utilities, which create the Meta Data Catalogs.

After completing these steps, you are ready to use Classic Connect operational components with your tools and applications to access your non-relational data.

Technical Information and Specified Operating Environment

Hardware Requirements

Minimum Disk Space Requirements for Installation: To install a Classic Connect system and the required C Runtime files, approximately 66 cylinders of disk space are required. During installation, all the libraries referenced in this section are created. All disk space amounts are for 3390 storage units.

The Classic Connect system is installed using the IBM MVS SMP/E product. The SMP/E product is used to apply, monitor, and ensure the integrity of service updates to the products installed under its control. SMP/E installs a target set of run-time libraries as well as a distribution set of backup libraries. The target library DD names, as well as the low-level qualifiers of their data set names, all begin with the letter "S"; the distribution libraries begin with the letter "A." Both sets of libraries and the disk requirements of each are shown in the following table:

                                                  Disk Space
Contents                           Component      Requirements
APF authorized load library        SDJXLOAD       15 cylinders
Configuration parameters           SDJXCONF       1 cylinder
Sample JCL                         SDJXSAMP       1 cylinder
C runtime library                  SDJXSASC       6 cylinders
  (packaged separately)
Macro library for use with         SDJXMAC        1 cylinder
  SYSTEM exits and client
System messages catalog            SDJXMENU       4 tracks
SMP/E "Distribution" copy          ADJXLOAD       15 cylinders
SMP/E "Distribution" copy          ADJXCONF       1 cylinder
SMP/E "Distribution" copy          ADJXSAMP       1 cylinder
SMP/E "Distribution" copy          ADJXMAC        1 cylinder
SMP/E "Distribution" copy          ADJXMENU       4 tracks

Operational Disk Space Requirements: In addition to the installation libraries, if you are running the Data Servers as started tasks, you need to place the Data Server JCL procedure in a procedure library that is accessed when a start command is issued to activate a Data Server. Because you already have these procedure libraries allocated, and the size of the Data Server procedures is relatively small, no additional disk space should be required for this aspect of implementing Classic Connect.

The only other set of permanent data sets that you need are for the Meta Data Catalogs. The disk space required for the Meta Data Catalogs depends on the number of non-relational-to-relational mappings that you have defined. Additionally, you will need to decide whether to create new sets of the Meta Data Catalogs for each application that you create or whether all of, or a group of, related applications will share the same Meta Data Catalogs.

Disk space requirements for the Meta Data Catalogs are minor. The Meta Data Catalogs consist of index and data components. The Meta Data Catalogs contain approximately 100 logical tables with a total of approximately 2,000 columns. The disk space requirement for the index component is one cylinder, while the data component is three cylinders. You can safely assume that approximately five cylinders of disk space is required for each set of Meta Data Catalogs that you create.

To summarize, you will need about 60 cylinders of 3390 disk space for the basic operational infrastructure and another three to five cylinders for each set of Meta Data Catalogs that you implement. For planning purposes, assume you will need approximately 71 cylinders of permanent disk space to operate Classic Connect.

Another, and much more difficult to estimate, disk space requirement is for temporary disk space required to process user queries. If you use the immediate return of data feature, many types of queries do not require any temporary disk space. However, if a query contains a scalar function or a sorting operator (for example, an ORDER BY clause), then the result set must be spooled to temporary disk for summarization or sorting. If the result set is small, the use of temporary disk space may not be necessary based on the size of the file buffer cache.

For a query, once the file buffer cache is exhausted, the result set is spilled to temporary DASD. You control the size and location of where the temporary files are written using the LD TEMP SPACE configuration parameter.

Assume that the amount of temporary storage required is twice the size of the total result set. For example, if the result set is 3 MB, then approximately 6 MB of temporary storage are required to stage the result set output.

The total amount of temporary DASD that is required is based on the types of queries and the number of concurrent users. For example, if you have 50 concurrent users all issuing queries that retrieve 3 MB of data, and the queries contain an ORDER BY clause, then 300 MB of temporary DASD are required to service all 50 users concurrently.

Runtime Storage Requirements: The amount of virtual storage required to operate a Classic Connect system varies based upon these factors:

  • The number and types of components configured
  • How each component is configured
  • The number of concurrent users being serviced
  • The complexity of the queries being run by each user

Tape Requirement: The system must have an appropriate tape unit for installing the product.

Hardware Requirements for the Data Mapper The Data Mapper runs on an IBM-compatible workstation PC.

Note: PTF requirements are subject to change. Always check the DataJoiner Web site for the latest PTF levels:

For APPC connectivity between Classic Connect and DataJoiner for Windows NT, you need Microsoft™ SNA Server V3.0 service pack 3, or later.

APF Authorization Requirements: Both the Data Server and Enterprise Server require the Classic Connect load library to be APF authorized in most situations, including for the configuration used in the Installation Verification Procedure (IVP). After the system installation has been verified, APF authorization can be removed if the configuration does not include any use of the Cross Memory transport layers or any of the security or accounting Exits. The C runtime library must be APF-authorized.

Software Requirements for the Data Mapper: One of the following:

  • Microsoft Windows 95/98, or
  • Microsoft Windows NT


Compared to DataJoiner Classic Connect V1.2 Classic Connect V2.1.1 is upwardly compatible with DataJoiner Classic Connect 1.2.

Classic Connect V2.1.1 is:

  • Easier to install and configure
  • More reliable due to greatly reduced complexity
  • Up to three or more times faster — but that is very dependent on the query itself.
  • With the Enterprise Server we have more user concurrency. Each Data Server easily supports 50 users concurrently. An Enterprise Server can then be used to dispatch queries across multiple Data Servers allowing support of hundreds of users.

There is also a change in the terms and conditions. DataJoiner Classic Connect V1.2 was licensed under the IBM International Program License Agreement (IPLA). Classic Connect V2.1.1 terms and conditions fall under the IBM Customer Agreement (ICA) or the IBM International Customer Agreement (IICA).

Planning Information

Installability: To facilitate conversion DataJoiner can support simultaneous access of V1.2 and V2.1.1 of Classic Connect. This is achieved by using different protocols when creating a server mapping within DataJoiner. Separate environment variables point to the separate Classic Connect configuration files.

In this way current users of DataJoiner Classic Connect V1.2 can install the new Classic Connect V2.1.1 and migrate DataJoiner based applications one at a time. This saves users from having to upgrade all software and applications simultaneously.

Additionally, the DataJoiner Classic Connect V1.2 Projection Utility can be used with Classic Connect V2.1.1 to create new Meta Data Catalogs. However, to exploit the new functions, VSAM and IMS data should be re-mapped using the new Classic Connect V2.1.1 Data Mapper.

Direct Customer Support: Direct customer support is provided by S/390 Support Line. This fee service can enhance your productivity by providing voice and electronic access into the IBM support organization. S/390 Support Line will help answer questions pertaining to usage, how to and suspected software defects for eligible products.

Installation and technical support is provided by IBM Global Services. For more information on services, call 800-IBM-4YOU (426-4968).

Packaging: The Classic Connect V2.1.1 program will be shipped on two tapes:

  • Classic Connect V2.1.1 machine-readable material
  • C Runtime library

There is a choice of three formats:

  • 3480 1/2-in Data Cartridge; 34K bpi uncompressed
  • 4-mm Data Cartridge; Modified; 2GB uncompressed
  • 9-Track 6250 BPI Distribution Tape Reel (DTR)

The Data Mapper component is shipped with DataJoiner PTFs.

For all other program copies, specify the PSLC No-Charge (NC) Identifier feature on the licenses.

There are two tables of PSLC Feature numbers. The first table is to be used when Classic Connect is to access IMS data. The second table is for access to VSAM data.

Also, specify the feature number of the desired distribution medium.

Examples of Table Use

Example 1: For a single machine with 11 MSUs and accessing VSAM, the PSLC features would be: 1015 — quantity 1 and 1016 — quantity 8.

Example 2: For two machines in a Parallel Sysplex which have an aggregation of 60 MSUs and used for accessing VSAM, the PSLC features would be:

  • PSLC chargeable license #1:
    • 1015 — quantity 1, 1017 — quantity 1,
    • 1018 — quantity 5, and 1019 — quantity 1
  • PSLC no-charge license #2: 1024 — quantity 1

Customization Options: Select the appropriate feature numbers to customize your order to specify the delivery options desired. These features can be specified on the initial or MES orders.

Example: If publications are not desired for the initial order, specify feature number 3470 to ship media only. For future updates, specify feature number 3480 to ship media updates only. If, in the future, publication updates are required, order an MES to remove feature number 3480; then, the publications will ship with the next release of the program.
