Database Management Systems (DBMSs)

Lists supported and tested DBMSs along with the Enterprise Server 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 Customer Care for availability of Extended Support Plus options.
Encourages you to include third-party RDBMS consideration when planning an upgrade to your Micro Focus product

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 version of Enterprise Server supports the following Database Management Systems:

COBSQL (Pro*COBOL)
HCO for DB2 LUW
HCO for SQL Server (HCOSS)
OpenESQL

COBSQL (Pro*COBOL)

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

Host Compatibility Option (HCO)

Host Compatibility Option requires that you have one of the following software products installed and configured:

IBM DB2 Connect - Personal, Enterprise, Application Server or Unlimited Edition
IBM DB2 LUW - Workgroup or Enterprise Server Editions including Advanced versions
IBM DB2 LUW - Express or Express-C Edition
IBM Data Server Client (assumes installation of a remote DB2 LUW Server product)

Testing

For this version, HCO for DB2 LUW was tested with versions 10.5 and 11.1, and 11.5

HCO for SQL Server (HCOSS)

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

Availability

Feature/Platform	32-bit	64-bit
x86-64 running Windows	X	X

Database Migration

HCOSS Client Host node

SQL Server 2014 or later [15]
Microsoft .NET Framework 4.7.2
Microsoft OLE DB Driver for SQL Server (MSOLEDBSQL)
Note: Microsoft recommends MSOLEDBSQL only, as all other versions are deprecated or are no longer maintained. However, if MSOLEDBSQL is not installed, SQL Server Native Client (SNAC) is used if available.
Microsoft OLE DB Provider for DB2 version 5.0 or later
Notes:
- Be sure to configure the OLE DB Provider to connect to the mainframe. See your Microsoft documentation for details.
- When using Microsoft OLE DB Provider for DB2 version 6.0, set the Extract Schema Cast STATEMENT column to VARCHAR during SysViews extract option.

SQL Server Target Host node

SQL Server 2014 or later [15]

Mainframe DB2

IBM-supported z/OS DB2 versions only

Note: If you intend to develop applications on your local machine, but deploy applications to a SQL Server database on a remote machine, configure the remote machine using the requirements listed in the Deploying Native Applications > Deployment Machine section later in this topic.

Application Migration

ADO.NET applications: ADO.NET applications require SQL Server 2014 or later and SqlClient Data Provider in .NET Framework 4.x
Note: Microsoft recommends .NET Framework 4.5.2

OpenESQL

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

Availability

Feature/Platform	Native, ADO.NET Managed, and JVM COBOL 32-bit	Native, ADO.NET Managed, and JVM COBOL 64-bit	PL/I 32-bit	PL/I 64-bit
x86-64 running Windows	X	X	X	X

XA Switch Module

The ODBC One-phase Commit, SQL Server, and PostgreSQL (early adopter program) switch modules are provided and available on the same platforms as are indicated in the Availability section above.

Native COBOL and PL/I

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

.NET COBOL

OpenESQL supports access to relational databases using compliant .NET framework drivers
OpenESQL has been tested against the following ADO.NET data providers:
- Microsoft provider for SQL Server
- Microsoft provider for Oracle
- IBM DB2
- Oracle Data Provider for .NET (ODP.NET) - fully managed and unmanaged providers
- OleDb
- Managed ODBC .NET providers
- Npgsql 3.2.2 for EDB PostgreSQL

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 10.5 DB2 LUW 11.1 DB2 LUW 11.5	db2jcc4.jar (and db2jcc_license_cu.jar)
Oracle 18C and 19c	ojdbc7.zip¹
Microsoft SQL Server 2014 Microsoft SQL Server 2016 Microsoft SQL Server 2017 Microsoft SQL Server 2019	sqljdbc4.jar²
EDB PostgreSQL 10.5 and 11.x	postgresql-42.0.0.jre7.jar
¹Some Oracle JDBC drivers are distributed as .zip rather than .jar files. ² On Windows platforms, if you are not using Windows authentication, no additional resources are required. However, if you are using Kerberos authentication with a driver version of 4.0 or later, although integrated authentication is not required, you might need to follow additional configuration steps as described in the driver documentation. No additional resources are required for UNIX platforms.

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 in this documentation set for instructions on downloading, installing, and configuring the open source JNDI server Simple-JNDI for this purpose.

Testing

For this version, OpenESQL was tested with:

Oracle 18c and 19c
DB2 LUW 10.5, 11.1, and 11.5
SQL Server 2014, 2016, 2017, and 2019
PowerLinux LE on remote Linux server using DB2 LUW 10.5 only
EDB PostgreSQL 10.x (where x>=5), and 11.x
MySQL 5.7 (5.3 ODBC drivers only)

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.

Planned

Support for the following is planned for future release:

Azure SQL Database (Managed Instance)
Azure SQL Database (Logical server)
Amazon Aurora PostgreSQL-Compatible Edition
