Database Management Systems (DBMSs)

Lists supported and tested DBMSs along with the Visual COBOL features that use them.

All RDBMS testing is done on both 32- and 64-bit platforms based on RDBMS client software availability.

With regard to support for each of these third-party RDBMS supported version, Micro Focus:

Provides support until the standard end-of-service (EOS) date provided by the RDBMS vendor
If your deployment requires support for a given RDBMS beyond the vendor's EOS dates, check with OpenText Support for Micro Focus Products for availability of Extended Support Plus options.
Encourages you to include third-party RDBMS consideration when planning an upgrade to your Visual COBOL

With regard to resolving reported issues with Micro Focus software while using a third-party RDBMS, Micro Focus :

Attempts to resolve issues for supported DBMSs on tested or untested platforms
Investigates issues involving planned but not yet supported RDBMSs, and attempts to resolve non-architectural issues that also occur in the latest supported RDBMS version

This release of Visual COBOL supports the following Database Management Systems:

COBSQL (Pro*COBOL)
DB2 ECM
OpenESQL

COBSQL (Pro*COBOL)

Note: COBSQL (Pro*COBOL) is supported for native COBOL only.

Before deploying a COBSQL application, be sure to install and configure all applicable third-party software.

Availability

Operating System/Platform	32-bit	64-bit
x86-64 running Red Hat Linux
x86-64 running SUSE Linux
IBM Power System running AIX
IBM System Z running Red Hat Linux
IBM System Z running SUSE Linux
Itanium running HP-UX
x86-64 running Solaris

XA Switch Module

When the Enterprise Server feature is enabled, the Oracle XA switch module is provided for COBSQL (Pro*COBOL), and is available on the same platforms as are indicated in the Availability section above. Oracle Instant Client fully supports all 1PC functionality with Pro*COBOL applications.

Restriction: The Oracle Instant Client does not support the 2PC functionality of the Oracle XA switch module. To use 2PC functionality with Pro*COBOL applications, you must install Oracle Client, not Instant Client.

Certification of RDBMS Precompilers for Native COBOL

Certification of RDBMS precompilers with Micro Focus products is the responsibility of the RDBMS vendor, rather than Micro Focus . Certification information can be found within the relevant Oracle documentation. If you have an https://support.oracle.com/epmos/faces/DocumentDisplay?id=43208.1 , document # 43208.1 provides details of all language compilers certified by Oracle for use with their precompilers.

Preprocessors

COBSQL supports the following database preprocessors:

Oracle Pro*COBOL versions 19c and 21c
Sybase Open Client Embedded SQL/COBOL version 11.1 and later
Informix Embedded SQL/COBOL version 7.3 and later

Compiling

On x86 and x86-64 platforms, when compiling with COBSQL for use with Oracle, do not use the COBSQL directive option NOMAKESYN, since this directive results in COMP host variables, and on Intel platforms these are incompatible with the native byte order expected by Oracle.

Supported/tested version

For this release, COBSQL was tested with Oracle Pro*COBOL versions 19c and 21c.

Planned support

Support for the following is planned for a future release:

Oracle 23c

DB2 ECM

Before developing or deploying a DB2 ECM application, be sure to install and configure all applicable third-party software.

Note: DB2 ECM is supported for native COBOL only.

Availability

Operating System/Platform	32-bit	64-bit
x86-64 running Red Hat Linux
x86-64 running SUSE Linux
IBM Power System running AIX
IBM Z System running Red Hat Linux
IBM Z System running SUSE Linux
Itanium running HP-UX
x86-64 running Solaris
SPARC running Solaris

XA Switch Module

When the Enterprise Server feature is enabled, the DB2 XA switch module is provided and is available on the same platforms as are indicated in the Availability section above.

Certification of RDBMS Precompilers for Native COBOL

Certification of RDBMS precompilers with Micro Focus products is the responsibility of the RDBMS vendor, rather than Micro Focus . You can find IBM document certification information for DB2/COBOL applications within the IBM Information Center for DB2, in the topic Support for database application development in COBOL .

Preprocessor

DB2 ECM supports the following database preprocessors:

IBM DB2 LUW version 11.1 and later
IBM DB2 Connect version 11.1 and later

Supported/tested versions

For this release, DB2 ECM was tested with DB2 LUW 11.1 and 11.5.

OpenESQL

Before developing or deploying an OpenESQL application, be sure to install and configure all applicable third-party software.

Availability

Operating System/Platform	COBOL native and JVM 32-bit	COBOL native and JVM 64-bit
x86-64 running Red Hat Linux
x86-64 running SUSE Linux
x86-64 running Solaris
IBM Power System running AIX
IBM Z System running Red Hat Linux
IBM Z System running SUSE Linux
Itanium running HP-UX
SPARC running Solaris

XA Switch Module

When the Enterprise Server feature is enabled, the ODBC One-phase Commit switch module is provided and is available on the same platforms as are indicated in the Availability section above.

The SQL Server and PostgreSQL switch modules are available on the following platforms:

x86-64 running Red Hat Linux
x86-64 running SUSE Linux

Native COBOL

OpenESQL supports access to relational databases using ODBC 3.0-compliant drivers
Refer to your driver vendor's documentation to determine whether your driver is suitable for use with OpenESQL

JVM COBOL

OpenESQL supports access to relational databases using JDBC 4.0-compliant JDBC drivers. The following table shows the tested DBMSs and their corresponding JDBC driver filenames:

Tested DBMS Versions	JDBC 4.0 Compliant Drivers
DB2 LUW 11.1 DB2 LUW 11.5	db2jcc4.jar (and db2jcc_license_cu.jar )
Oracle 19c Oracle 21c	ojdbc7.zip ¹
Microsoft SQL Server 2017 Microsoft SQL Server 2019	sqljdbc4.jar
EDB PostgreSQL 13.x and later	postgresql-42.0.0.jre7.jar
¹ Some Oracle JDBC drivers are distributed as .zip rather than .jar files.

To use JDBC DataSource Objects, you must also install and configure a JNDI server.

If you are using a Java application server, it includes a JNDI server you can use to configure DataSource objects. This process is described in the Java documentation for the application server.
If you are not using a Java application server, or if you require a standalone JNDI server to configure DataSource objects for initial evaluation and development, see the To install and configure Simple-JNDI topic for instructions on downloading, installing, and configuring the open source JNDI server Simple-JNDI for this purpose.

Supported/tested versions

For this release, OpenESQL was tested with:

Oracle 19c and 21c
DB2 LUW 11.1 and 11.5
SQL Server 2017, 2019, and 2022
Microsoft Azure SQL Database
Microsoft Azure SQL Managed Instance
PostgreSQL GDG community edition (early adopter program) and EDB PostgreSQL 13.x, 14.x, and 15.x
Amazon AWS Aurora and RDS for PostgreSQL 13.x, 14.x, and 15.x
MySQL 8.0 on the following UNIX platforms:
- x86-64 running Red Hat Linux
- x86-64 running SUSE Linux

Note: Micro Focus provides compatibility for PostgreSQL and MySQL but does not directly contribute to or support either open source project. Any issues relating to the functionality of either DBMS should be addressed through an open source support vendor.
