Improve data security by making sure all references to sensitive data are cleared before the memory holding that data is freed.

Note that no memory was leaked nor was any sensitive data exposed prior to this change. This change applies to the way in which the Universal Agent applications are built. Some compilers may "skip" a call to clear memory in situations where that that memory is immediately freed in the next statement. This is an undesirable optimization, and this change prevents the call to clear the memory from being skipped.

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.

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.

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-13913

UAGSRV

Restores the list of secondary Agent name(s) to the following Universal Controller locations:

IBM i

UAGSRV

Add support for executing scripted IBM i Virtual Terminal sessions from a Universal Agent batch environment. This is required to support the scenario of automating work that must be run from an interactive session, which may involve interaction with menu panels for a command or application.

Support for this feature will include the following enhancements:

• The introduction of a new command (UNVVTSND) to facilitate interaction with a virtual terminal session.

• The introduction of a new command (UNVVT) to provide enhanced CL script processing capabilities, along with dedicated functionality to facilitate scripting Virtual Terminal sessions with UNVVTSND.

D-13864

Ensures that an IBM i task will always execute with the credentials specified in the task's definition. If no credentials are specified, the behavior is unchanged and the task will continue to run as the Universal Broker user.

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.

UBROKER

When the path to a Universal Broker's .ipc file – which is used to support the Universal Broker's component interface on Unix systems – is greater than 80 characters, its value inside the ubroker.bif file (see UBROKER_BIF) is truncated. This will cause Universal Broker startup to fail. This fix provides support for a file path up to 2000 characters (subject to system to system limits imposed by some platforms).

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).

UAGSRV

Provides a change that removes restrictions on the number of environment variables that can be provided to a Unix or IBM i task. The previous implementation limited the number of environment variables to 2000 on the affected platforms, but Universal Agent will now recognize as many environment variables as the system supports.

D-13518

All

UAGSRV

Fixes a regression introduced in Universal Agent 7.8.2.0 that could affect the way string arrays are exchanged between Agent components and with OMS. 

The affected code is executed on all platforms, but the problem was exposed by a situation specific to z/OS. In that situation, we observed instances where a message sent from a secondary z/OS Agent to a primary z/OS Agent in a sysplex configuration could lose some formatting. The primary content of the message was intact, but the loss of formatting caused an exception to be reported in the Universal Controller log when it received that message from OMS. The most visible result that the task instance had no Restartable Job Steps even though the task itself finished successfully.

D-13549

UAGSRV

Fixes a problem in which the Universal Agent for Windows process could crash at startup during Universal Extension task initialization. Specifically, the issue occurred within the Agent's Python discovery processing.

D-13578

z/OS

UAGSRV

Ensure that the UAG Server's configured CODE_PAGE is honored during OMS message processing.

Specifically, this fix addresses a problem with z/OS Task parameter translation when the z/OS system environment is configured to use a codepage other than IBM1047 (UAG Server's default codepage). The problem applies to the following situation:

• The z/OS Task defines one or more task parameters

• UAG Server uses the parameter(s) to construct a SET statement for insertion into the task's JCL

• A parameter's name or value contains a character whose IBM1047 encoding is different from the encoding used by the z/OS system's configured codepage (e.g., IBM1141)

Prior to this fix, the parameter's name and value would always be translated from UTF8 to IBM1047, even if the UAG Server's configured codepage were set to something other than IBM1047. 

With this fix, UAG Server will now honor its configured codepage and translate the parameter name and value accordingly. The default is still IBM1047.

Note that a similar defect, D-13592, is provided for this release that fixes translation of parameters used for JCL variable substitution. These are parameters whose names start with *@.

D-13592

z/OS

UAGSRV

Ensure that the UAG Server's configured CODE_PAGE is honored during OMS message processing.

Specifically, this fix addresses a problem with z/OS Task parameter translation when the z/OS system environment is configured to use a codepage other than IBM1047 (UAG Server's default codepage). The problem applies to the following situation:

• The z/OS Task defines one or more task parameters that start with *@

• UAG Server uses these parameters to perform variable substitution in the z/OS task's JCL

• The z/OS environment is configured to use a codepage that uses an EBCDIC encoding for the '@' symbol that is not the same as IBM1047 (0x7C). Of the codepages provided by the Universal Agent install, the following use a different encoding for the '@' symbol:

  • IBM1141, IBM1144, IBM273, IBM280 (0xB5)

  • IBM1142, IBM277 (0x80)

  • IBM1143, IBM278 (0xEC)

  • IMB1147 (0x44)

If your z/OS system's codepage is configured with one of the above codepages, this fix will provide the ability to retain the '@' symbol in the task parameter definition and your z/OS task's JCL.

Prior to this fix, the parameter would always be translated from UTF8 to IBM1047, even if the UAG Server's configured codepage were set to something other than IBM1047. 

With this fix, UAG Server will now honor its configured codepage and translate the '@' symbol correctly. The default is still IBM1047.

Note that a similar defect, D-13578, is provided for this release that fixes translation of parameters used for JCL SET statements.

D-13628

UAGSRV

Fixes the behavior for an Agent File Monitor task executed under the following conditions:

• The task executes on Universal Agent 7.8.0.0, 7.8.0.1, or 7.8.1.0 for Windows

• The task has a Monitor Type of "Change"

• The task is started via an Agent File Monitor Trigger

Prior to this fix, the file monitor task that satisfies the above criteria would only trigger once.
