Oracle Database on z/OS Support Status

The final patch set for Oracle Database 10g Release 2 will be the last release Oracle delivers for the z/OS platform. Customers can continue to run the terminal patchset release of Oracle Database 10g Release 2 on z/OS for as long as they want with support options to meet both their current and future needs. Oracle will not be delivering an Oracle Database 11g release for z/OS.

1.      What is the Support plan for Oracle Database products on z/OS?

The final release for Oracle Database including the Client, and Oracle Programmer (which includes the Access Manager for IMS, Access Manager for CICS, OCI, and pre-compilers for COBOL, Fortran and PL/1) on z/OS will be the final patchset for 10.2.

Premier Support will be extended two years for z/OS and will end in July 2012

Extended Support, which starts after Premier Support ends, will be offered indefinitely – this represents an exception to the standard Oracle Lifetime Support Policy. Customers choosing not to enroll in Extended Support will be eligible for Sustaining Support.

The following table summarizes these three standard support levels and what is provided. For further details about Oracle’s Lifetime Support Policy, please see:


Premier Support

Extended Support

Sustaining Support

Release 10.2 is the terminal release for z/OS

Continues for an additional two years beyond the five years specified in the Lifetime Support policy. Premier support for 10.2 ends July 2012.

Begins at conclusion of Premier Support and continues indefinitely – just for z/OS platform.

For customers not enrolling in Extended Support, available as long as paid support is in place.

Access to support tools, knowledgebases, tech experts




Technical support




Updates, fixes, security alerts and critical patch updates for 10.2


Yes – through July 2013 per base platform policy

See * below for extension offered for new versions of z/OS, CICS, IMS


Upgrade Scripts




Certification with new Oracle Products




Certification with existing third party products/versions




Certification with new third party products/versions


Standard policy is “No”.
However – this is “Yes” for certain IBM products for z/OS*


*    Upon customer request, as new versions of IBM z/OS, CICS, and IMS are released, Oracle will test with the 10.2 terminal release for compatibility. Extended support customers are entitled to any updates or fixes to ensure this compatibility. This compatibility assurance will continue indefinitely. Sustaining Support customers will not be entitled to these updates or fixes.

1.      Will customers be forced to move off of the mainframe?

No! These z/OS products are supported under Oracle’s Lifetime Support policy. This means you will receive and be entitled to Oracle’s support as long as you have paid support.

Over time, per Oracle’s standard Lifetime Support policy, products move from Premier to Extended to Sustaining support. Under Extended Support, Oracle does not perform any further certifications for newer versions of z/OS, CICS or IMS. Under Oracle’s Sustaining Support, no further updates, bug fixes, security alerts or critical patch updates occur for that release.

However, for z/OS, Oracle is modifying its Extended Support policy.  Upon customer request, as new versions of IBM z/OS, IMS, CICS and other related software are released, Oracle will test with the Oracle 10.2 terminal release for compatibility.   Extended support, which starts in August 2012, will continue indefinitely.

Customers desiring to remain on the mainframe and upgrade to future releases of the Oracle Database can move to the open systems mainframe environment and run Oracle for Linux on System z. Oracle will continue to support the mainframe platform by offering the Technology Products on Linux for System z on a timely basis from their initial release. For further information on this option, customers should consult their Oracle Account representative.

2.      Will fixes, security alerts and critical patch updates (CPUs) continue to be provided for all supported releases?

Yes. Fixes, security alerts, and critical patch updates will continue to be provided through Premier Support and Extended Support for the 10.2 releases ported to z/OS. Per Base Platform policy after July 2013 Extended Support will be limited to Severity 1 fixes only; Critical Patch Updates will not be made available.  See Oracle Software Technical Support Policies.

3.      Will there be a  64-bit version of Oracle Database 10g Release 2?

Oracle plans to deliver a 31-bit version of the product as is currently done, but has no plans for a 64-bit version.

4.      Will the Oracle products (e.g. database, Oracle Programmer) be upgraded and certified with new versions of z/OS and other relevant IBM software?

Yes. They will be done as requested by customers through Premier and also Extended Support per the exception discussed above.

“Oracle Programmer” consists of Oracle Clients (ODBC, OCI), Pre-compilers (Pro*COBOL, Pro*PL/1, Pro*Fortran), Access Manager for CICS and Access Manager for IMS. Each of these elements will be maintained, upon customer request, to remain current with the latest releases of their counterparts. For example, when a new release of CICS is issued, Oracle will test and certify that the Access Manager for CICS is compatible. A similar process will occur for the other elements of “Programmer” as changes occur. 

5.      Will an Oracle Client (e.g Access Manager for CICS or OCI) running on z/OS be able to access later version (beyond 10.2) of the database running on a different platform?

Yes, per Oracle’s policy regarding dissimilar client/server versions of the database as explained in  <Note:207303.1>, Client / Server / Interoperability Support Between Different Oracle Versions

Oracle will continue to test past 2014, at its discretion, new versions of the database running on non-z/OS platforms with the older 10.2 client running on z/OS.

6.      Will there be an “additional fee” for Extended Support?

The standard fee for extended support will apply for each year customers wish to have Extended Support.

7.      Who may customers speak with to discuss this?

Please contact your Oracle account representative.

8.      What level of support will customers get through this period for z/OS and how quickly will patches, bug fixes, Service Requests (SRs) be handled?

Customers will receive the same level of support that they had previously. There is no change in the delivery time of SR handling or bug fixes. Service Requests are prioritized by severity level, not by platform.

9.      What is the status of the Oracle Transparent Gateway for DB2?

Oracle Transparent Gateway for DB2 is being stabilized as well. Oracle Database 10g Release 2 is the final release for this product. Oracle will not continue active development of this product and no new enhancements will be made. Oracle will however continue to provide the same level of support to existing customers.

10.  What are the plans to support the Transparent Gateway for DB2?

Oracle will continue to support the Transparent Gateway for DB2. Premier support will be available to existing customers until July 2011 per Oracle’s standard Lifetime Support policy.

Oracle is streamlining the offerings for accessing the different platform versions of DB2. Oracle recommends that customers use the Database Gateway for DRDA to access DB2 on z/OS. The Database Gateway for DRDA enables a customer to access DB2 on any platform, including z/OS and AS/400.  Oracle recommends customers migrate to the Database Gateway for DRDA to maintain the highest level of support.

11.  Can Linux for IBM System z run on my GP (General Purpose) processors, or can it only run on IFL (Integrated Facility for Linux) processors?

Linux for IBM System z can run on GP and IFL processors.

12.  Does Linux for System z run in LPAR's (Logical Partitions) natively or just under z/VM?

Linux for System z can run in LPAR's natively and as a guest under z/VM.
