D-11676

Unix

UAGSRV

Fixes an intermittent issue where UAGSRV may terminate abnormally when stopped with the Universal Control utility (UCTL). The failure is not common, and was observed only when the UAG Server JTSK_NUM configuration option was set to its maximum value of 64.

D-12222

z/OS

UAGRERUN
UAGU84
UAGUSI

Resolves unexpected behavior for a z/OS task, under the following conditions:

  • The z/OS task contains a Step Condition that is defined treat an ABEND as an expected result, by specifying an action of Continue/Success

  • A subsequent step in the z/OS task's JCL contains an EXEC COND= parameter that references the ABENDed step, that would normally prevent execution of the step

Prior to this fix, the EXEC COND= parameter is not honored when the ABEND occurs, and the step executes.

This fix ensures the Step Condition and the EXEC COND= configuration is honored.

D-12223

Windows

UAGSRV

Adds the Windows network error ERROR_UNEXP_NET_ERR (59) as a retry-able error condition for a Windows File Monitor task, when file monitor fault tolerance is enabled.

B-13286

z/OS

UAGSRV

Extend the AUTOMATIC_FAILOVER option to support the primary_secondary value, which will instruct a Universal Agent configured with a SYSPLEX_ROLE of primary to start as a secondary Agent if another primary Agent is already running.

Note

The AUTOMATIC_FAILOVER option continues to support a default value of never, which will disable automatic failover and will require failovers to be managed manually via a Universal Broker MODIFY command. 

B-13287

z/OS

UAGSRV

Extend the AUTOMATIC_FAILOVER option to support the secondary_primary[n] value, where n is an optional numeric value that sets a priority to determine which secondary Agent (among several active secondary Agents) will take over as primary.

Note

The AUTOMATIC_FAILOVER option continues to support a default value of never, which will disable automatic failover and will require failovers to be managed manually via a Universal Broker MODIFY command. 

B-13288

z/OS

UAGSRV

Added the (mutually-exclusive) ZOS_JOB_SYSAFF and ZOS_JOB_SYSTEM configuration options that can manage a zOS task's execution via a SYSAFF or SYSTEM JOB card parameter, respectively.

B-13292

z/OS

UAGSRV

Extend the AUTOMATIC_FAILOVER option to support the always_primary value, which will force an Agent whose SYSPLEX_ROLE is primary to always start as a Primary Agent. Any other Agent running as a Primary Agent will become a Secondary Agent when this Agent starts.

Note

The AUTOMATIC_FAILOVER option continues to support a default value of never, which will disable automatic failover and will require failovers to be managed manually via a Universal Broker MODIFY command. 

B-14071

Unix

UAGSRV

Add the KILL_PROCESS_TREE option to control how UAG Server responds to a Cancel task command from Universal Controller. When yes, the entire process tree is terminated via SIGTERM. Any process within the tree that is still running after 10 seconds is terminated with a SIGKILL. UAG Server will confirm that all processes in the process tree are terminated before it notifies the Controller of the termination.

To preserve compatibility with existing behavior, the default value for this option is no, which can prevent the termination of a process in the tree that ignores the SIGTERM signal. This may cause the task's status in the Universal Controller to show Cancelled although the (now orphaned) process continues to run.

Note

This new option has no effect on tasks running with sudo authority. Such tasks will not receive a SIGTERM signal and are always terminated immediately with a SIGKILL. 

B-14630

Unix
Windows

UAGSRV
UFTP

Add the ability to retrieve values from the Universal Controller File Transfer Task form that support transfers using explicit FTPS (that is, FTP with SSL). 

Note

Explicit FTPS (FTPES) support was added to the Agent in the 7.1.0.0 release with B-10691. The change delivered in Universal Agent 7.2.0.0 provides full support and integration with the File Transfer Task.

B-14725

Unix
Windows

UAGSRV
UEXT

Add full support for Universal Monitor tasks, including the ability to reconnect to Universal Extension tasks (executed on behalf of the Monitor task) that continue to run when an Agent is restarted.

Note

The HP-UX and z/OS agents do not provide the Universal Extension. 

D-10379

Windows

UAGSRV

Fix an issue where a File Monitor task running on a Windows Agent fails to recognize Unicode characters.

D-10417

z/OS

UAGSRV

Fix an issue that prevents a z/OS Agent using IBM System SSL (that is, RACF-based keyrings) from connecting to an OMS Server.

D-10430

Unix
Windows

UAGSRV

When an SAP task instance is cancelled, ensure that the associated Universal Connector for SAP (USAP) process is cancelled as well.

D-10534

Unix
Windows

UAGSRV
UEXT

UAG Server may crash when a Universal Extension task references a credential token greater than 3000 characters in length.

Note

The HP-UX and z/OS agents do not provide the Universal Extension. 

D-10556

z/OS

UAGSRV

Fix an issue that prevented a file monitor task from locating datasets when a wildcard is used as the first character in the dataset pattern.

This restores behavior that existed prior to Universal Agent 7.0.0.0.

D-10559

Unix
Windows

UAGSRV

Fix an issue introduced in UA 7.1.0.0, where a Universal Task fails to properly resolve resolvable credentials when the credential variable is enclosed in double quotes.

D-10687

z/OS

UAGSRV

When running a File Transfer Task via a z/OS Agent, if the Local and/or Remote Filename values exceeded 72 characters, UAG Server failed to properly format the SYSIN DD statement in the JCL used to execute UFTP.

The z/OS Agent now ensures that such values are properly terminated at column 72 and continued to the next line.
