10715 | Unix | UAGSRV | Fix a problem where File Monitor tasks do not honor a specified stable period if there are multiple file monitor instances running with the same credentials.
|
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.
| |||||||
D-10716 | All | UAGSRV | Prevent a deadlock that may occur when a CHANGE File Monitor instance detects new matching files.
|
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. |
Unix
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. |

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.
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.

UDM
UDMSRV
Prevent an authentication error for a File Transfer task when the following conditions exist:
File Transfer task uses Universal Data Mover (UDM)
UDM script is used by the task
UDM script issues the
exec
orexecsap
commandexec
orexecsap
command uses thepwd
parameter- One of the built-in credential variables – $(ops_primary_cred_pwd) or $(ops_secondary_cred_pwd) -- is used for the pwd parameter's value
For example:
Code Block | ||
---|---|---|
| ||
open src=local dst=rmthost.ipaddr user=$(ops_secondary_cred_user) pwd=$(ops_secondary_cred_pwd)
exec src cmd="dir" user=$(ops_primary_cred_user) pwd=$(ops_primary_cred_pwd) |
Starting with UA 7.0.0.0, this will cause the resolved $(ops_primary_cred_pwd) value in the exec
statement to be enclosed in double quotes ("). The double quotes are retained when passed to UCMD Manager (or USAP for an execsap
statement). The double quotes will prevent successful password authentication.
UDM
UDMSRV
Fix an issue where an attempt to transfer PDS members from z/OS using UDM may result in an S0C4 ABEND.
When this occurs, the following error is reported:
