D-11929z/OSUAGSRV

Provide a new UAG Server configuration option,rerun_before_include, which is defined inUAGCFG00. This option controls whether a JCL INCLUDE statement should trigger the insertion of the UAGRERUN step.

Valid values and their meaning are as follows:

  • no-- a JCL INCLUDE statement willnottrigger insertion of a UAGRERUN step. This is the default, which matches the behavior in previous versions.
  • yes– a UAGRERUN step is inserted ahead of a JCL INCLUDE statement.

Description

D-10536z/OSUAGSRV

When the Universal Agent AGENT_IP configuration option specifies an IP address instead of a host name, eliminate the UNV0182E 'Cannot resolve' error, and accept the IP address as entered.

D-11431z/OSUAGSRV

Always insert the UAGRERUN step ahead of anyIFstatements in the JCL. This will ensure that UAGRERUN is executed ahead of any initialEXECorPROCstatement that may be enclosed within anIFstatement.

D-12221z/OSUAGSRV

Prevent a JCL error by ensuring that line numbers are not pulled into a JCL statement when

  • The JCL used for a z/OS task contains line numbers, and
  • A z/OS task variable is replaced with a value that is shorter than the variable name

The fix also prevents truncation of JCL statements that contain in-line data with hexadecimal values.

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 ServerJTSK_NUMconfiguration option was set to its maximum value of 64.

D-12222z/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-12223WindowsUAGSRVAdds the Windows network errorERROR_UNEXP_NET_ERR(59) as a retry-able error condition for a Windows File Monitor task, whenfile monitor fault toleranceis enabled.

D-11345WindowsINSTALLHonor the USE_TLS1_3 command line parameter for upgrades from UA 7.4.0.x and later. This was done for parity with Unix installs.

NOTE: Use of this option will apply configuration updates to all Universal Agent components that use SSL/TLS. Care must be taken when using this option for upgrades from UA 7.4.0.x and later, as TLS 1.3 may already be used for some Agent components and turned off in others. Using this option will cause all component configurations to enable TLS 1.3 support.

NOTE: The interactive system mode install for Windows will continue to display the dialog that uses a checkbox to enable Agent-wide TLS 1.3 support only when upgrading from releases prior to UA 7.4.0.0.
D-11392z/OSUAGSRVPrevent an error when a z/OS task is rerun under the following conditions:

D-11413zOSUDM
UDMSRV

Fixes a situation in which a UDM file transfer will fail if an attempt is made to allocate a zOS dataset with an EXPDT equal to one of the following special values:

  • 00000 - allocate the dataset with no expiration date

  • 98000 - used by some tape management systems control when datasets are uncataloged and tape volumes become available for re-use

  • 99000 - used by some tape management systems control when datasets are uncataloged and tape volumes become available for re-use

  • 99365 - allocate the dataset so that it never expires

  • 99366 - allocate the dataset so that it never expires

When none of the above 5-digit values are used, UDM will still expect a 7-digit expiration date as it did prior to this change.

D-11424zOS

UAGU83

D-11333Windows

PKG

Fixes a problem introduced in the 7.4.0.0 release that may cause upgrades from earlier versions to fail, if the Python distribution for Universal Agent is installed.

To prevent the problem during an upgrade to 7.4.0.x, perform the upgrade using the 7.4.0.1 (or later release). Upgrades to future versions are unaffected by this issue.

Update OpenSSL implementation to support TLS 1.3 sessions.

This feature provides the following configuration options:

  • max_ssl_protocol - controls TLS session negotiation by limiting the protocol that will be used
  • ctl_/data_ssl_cipher_suites (availability of these options varies by component) - allows the following TLS 1.3 cipher suites to be specified separately from – and mutually exclusive with – earlier TLS 1.x ciphers
    • TLS_AES_256_GCM_SHA384
    • TLS_CHACHA20_POLY1305_SHA256
    • TLS_AES_128_GCM_SHA256

The ability to enable TLS 1.3 across all Universal Agent components is available at install time via the --use_tls1_3 command line option (the Windows system mode install provides the equivalent USE_TLS1_3 command line property). When yes, this option sets the following configuration options:

  • max_ssl_protocol to "tls1_3" in omss.conf, uags.conf, uftp.conf, ubroker.conf, ucmd.conf, ucmds.conf, uctl.conf, udm.conf, udms.conf, uem.conf, and upps.conf.

  • encrypt to "yes" in ucmd.conf, ucmds.conf, and udm.conf

The interactive Windows installs also provides a new dialog with an option that, when checked, enables this configuration. This dialog is available for new installs and for upgrades from releases prior to 7.4.0.0.

Increase the maximum message size that can be transferred between UAG Server and OMS Server from 6 MB to 1 GB. 

The maximum message size allowed can be configured via the new OMS Server configuration option, MAX_MSG_SIZE. Similarly, a new MSG_CHUNK_OPTION option is provided to specify the maximum size for any single message transmitted. Any payload that exceeds this size will be split into multiple messages until the entire payload is transferred.

Using the new RERUN_PROC_NAME option, allows customized JCL that executes the UAGRERUN utility to be inserted into a job executed from a z/OS task.

This customized JCL would replace the default OPSSTP00 step that UAG Server inserts by default.

B-16745Unix (except HP-UX)

UAGSRV

Updates the handling for the EXTENSION_PYTHON_LIST, which allows users to configure an ordered list of Python interpreters to use for Universal Extension task execution.

Previously, the Python provided by the Universal Agent were installed, it would always be evaluated first. However, there were times where another Python that also satisfied the extension's requirement was preferred. As long as the Agent's Python was installed, the other Python would not be chosen.

With this change, if the Agent's Python is included in the EXTENSION_PYTHON_LIST value, the default ordering of the list is disabled and the Agent's Python is evaluation in the order in which it appears in the list.

For example, given a credential field called cred_test, the Key Location may be accessed using:

  • fields['cred_test']['key_location']
  • fields['cred_test.key_location']

The camelCase usage (i.e., keyLocation) is still recognized for backward compatibility, but that support could be dropped at any time so new extensions should use key_location.
