Agent 8.0.0.1 - May 12, 2026
Platform | Component | PTF(s) | Description | |
|---|---|---|---|---|
D-09560 | z/OS | UAGSRV | PS49001 | Ensure that a z/OS task instance's exit code and all of its step condition codes match what is reported by JES. This corrects a problem observed for some z/OS applications that set exit codes in an unexpected manner, which caused UAG Server to report exit code values greater than the 4095 allowed by z/OS. info Note that this fix represents a change in behavior for UAG Server. z/OS tasks with exit and/or step condition code processing whose conditions are authored using the errant values reported by UAG Server may no longer evaluate those conditions as they did before this fix. With this fix, you can now author those conditions with values that reliably match JES values. This only affects instances where UAG does not report exit or step condition codes that match JES. If UAG reports those values correctly in the z/OS task instance, the behavior will not change. |
D-11731 | z/OS | UAGSRV | PS49001 | Fixes a problem where a secondary Universal Agent in a sysplex configuration shuts down whenever it receives license information that does not permit secondary agents. This may only be a transient situation, as is the case when the the Universal Controller is upgraded or restarted. The secondary Agent will now stay active, but paused. The Agent will resume its processing when an updated license that allows secondary z/OS Agents is received. |
D-14044 | z/OS | UAGSRV | PS49001 | Ensure that z/OS external task monitors correctly identify jobs that fail with message IEF453 as a JCL error and a job failure. This fix also includes handling for WTO messages that are prefixed with an asterisk ('*'). Prior to this change, UAG Server was unable to properly detect the IEF453 message. |
D-14348 | z/OS | Install | All | This release introduces a significant change in the way Universal Agent maintenance releases for z/OS are prepared. Moving forward, all components subject to change after an initial .0 release will be provided in each maintenance delivery. This includes:
This change ensures that any 3pp vendor library updates -- particularly those that remediate CVEs -- are always available for any component that uses that library. This change means that the size of this PTF delivery is larger than previous maintenance releases. However, this significant size increase should only occur once, and the size of future PTF deliveries will stabilize. This larger PTF delivery requires a change to an existing installation dataset and a change to a JCL procedure used during Universal Agent installs and upgrades. A new install job is provided in the PTF distribution to deliver both of these changes. A new job will also need to be run before the UNVMTRCV job is run, which receives the PTFs. info Please read the updated instructions for installing PTF maintenance releases in the z/OS Installation - Cumulative PTF Maintenance page before installing this release. |
Agent 8.0.0.0 - March 31, 2026
Platform | Component | Description | |
|---|---|---|---|
B-14810 | z/OS | UAGSRV | Add TLS 1.3 connection support when Universal Agent components on z/OS are configured to use SystemSSL. |
B-22268 | z/OS | UAGSRV | Add the ability to apply a jobname filter to Universal Agent File Monitor tasks that execute on z/OS. If dataset activity is performed via TSO, this same jobname filter will accept a TSO user ID. |
B-22672 | z/OS | USAP | Add the ability to create SNC connections to an SAP server using USAP for z/OS. To implement this feature, support for the SAP Netweaver RFC libaries was also added to USAP for z/OS. See the SNC_MODE and SNC_QOP configuration options for information about how to configure this new feature. info This change provides a significant update to USAP for z/OS. Prior versions still rely on the legacy SAP RFC libraries. The versioning for USAP on z/OS was back-leveled to reflect this lack of contemporary RFC library support. This USAP that is now provided for z/OS has partity with the USAP provided for Unix and Windows. To implement this change required porting USAP for z/OS to a 64-bit module. This means the 64-bit C runtimes will be needed on your z/OS system. This should not be a problem, but it is an updated platform requirement. With this change, the LIBRFC shared object module previously installed with the Agent on z/OS is no longer provided. The SAP Netweaver RFC libraries must be available on your z/OS system in order for USAP to run. The libraries' location can be set using the LIBPATH configuration option. Finally, a copy of the sample RFC INI member (USPRFC00) installed to &HLQ..UNV.SUNVSAMP is no longer placed in &HLQ..UNV.UNVCONF during the install. You may use the sample USPRFC00 provided as a reference, but the file itself must reside on the USS file system. This location is set with the USAP_RFC_INI_DIR configuration option. This feature also changes the USPPRC JCL procedure installed to &HLQ..UNV.SUNVSAMP. The DD statement that pointed to the USPRFC00 member is no longer needed. While no REGION statement is provided by the sample JCL procedure, this updated version of USAP has different runtime requirements than the back-leveled version. It may be necessary to add a REGION statement to USPPRC or to your job cards to accomodate these newer requirements. ::: |
B-23143 | All | All | Upgrade the OpenSSL 3pp vendor library used by Universal Agent to OpenSSL 3.5.5 to ensure continued maintainability of OpenSSL updates and fixes. Virtually all Universal Agent components use OpenSSL for cryptographic functions. Not all components have user-facing visibility, but for practical purposes, a change to OpenSSL is a change to all Universal Agent components. |
B-23362 | z/OS | All | Certify Universal Agent 8.0.0.0 for z/OS 3.2. |
B-23529 | All | UAGSRV | Ensure that UAG Server refreshes the IP address of any hosts specified in its OMS_SERVERS list, to support DNS updates without having to cycle the Agent. |
B-23685 | All | UBROKER | Enhance security for the Universal Broker's external service interface by adding peer authentication support. When the new AUTHENTICATE_PEER configuration option is set to yes, the Universal Broker will require that any client that tries to connect to its external service interface provide a valid client certificate. This will ensure that only trusted clients can connect to the Universal Broker. |
D-11005 | z/OS | UAGSRV | Fix truncation of a message responsible for reporting secondary Universal Agent status to the Controller. The truncation could cause the Agent to show Active even if it were actually offline. |
D-13552 | All | UAGSRV | Ensures that an Agent's configured BUSINESS_SERVICES are part of any HELLO message the Agent sends to the Controller. This change was specifically intended to fix an issue where a transient Linux Agent would lose business service information after temporarily going offline. A persistent Agent on any platform would also benefit from this change if, for example, it were inadvertently deleted from the Controller. |
D-13947 | z/OS | UAGSRV | Ensure that a z/OS task does not fail with a JCL error when the task's job issues an IEFC677I message. Prior to this change, it may be possible for the Agent to fail with a S0C4 ABEND or return accurate error information to the Universal Controller. |
D-13958 | z/OS | UAGSRV | Prior to the Universal Agent's attempt to calculate a system workload value, ensure that the sample size value in an SMF record type 70-1 (SMF70SAM) is non-zero. This check will prevent a divide-by-zero exception (S0C9). |
D-13913 | z/OS | UAGSRV | Restores the list of secondary Agent name(s) to the following Universal Controller locations:
|
D-14036 | All (depending on component availability) | UAGSRV | Ensure that an attempt to establish an improper SSL/TLS session over the affected Server application's component interface is handled gracefully. |
D-14051 | All | UAGSRV | Fixes an issue where the UAG Server's configured SERVICE_TIMEOUT value is ignored when receiving messages from OMS. This fix will decrease the time it takes for UAG Server to detect a dropped connection with OMS, which will in turn decrease connection recovery times. |
D-14191 | Unix | UAGSRV | Fix a possible memory corruption when an application monitored by an Application Control Task is stopped immediately after the application is started. |
D-14197 | Unix | UFTP | Update the libSSH2 3pp vendor library used by UFTP to remediate Critical- and High-severity CVEs. |
D-14348 | All | All | Update the zlib 3pp vendor library to remediate Critical- and High-severity CVEs. The zlib library is used by all Universal Agent components, excluding the z/OS SMF exit modules. |
D-14409 | z/OS | UAGSRV (UAGRERUN) | Fixes a problem where the JCL for a z/OS task containing a backward reference to a DD statement in the same step prevented that step from being marked "Restartable" in the z/OS task instance. Steps that contain local backward references should be restartable. Steps that contain backward references to other steps in the job will continue to be non-restartable. |
D-14416 | z/OS | UFTP | Fixes a problem where the Universal FTP Client generates an excessive number of log messages that seems to indicate a failure when trying to establish a TLS 1.3 session. |
D-14448 | z/OS | UAGSRV | Fixes two memory leaks for UAGSRV on z/OS:
|
D-15569 | z/OS | UAGSRV | Fixes an issue where Universal Agents configured to use IBM's System SSL are unable to establish connections with z/OS 3.2 system. info This fix enables support for the following ciphers when using System SSL on any supported version of z/OS:
Use of either of the ECDHE-ECDSA-* ciphers requires that data sessions established between UCMD and UCMD Server and between UDM and UDM Server enable encryption. For information about enabling encryption for UCMD standard i/o redirection sesions, refer to one or more of the following:
For information about enabling encryption for a UDM data session, refer to one or more of the following: |
