Specifies the DDS node that controls the data dictionary in which the named program resides.
Specifies the alternate data dictionary in which the named program resides.
Note: Although dictnode and dictname are both optional parameters, if dictnode is specified and dictname is not specified, a "." delimiter must be included to represent the missing dictname parameter. For example:

An integer in the range 1 through 32767.
Varies the inactive wait time to the value established at system generation time by the INACTIVE INTERVAL parameter of the SYSTEM statement.
Specifies that DC/UCF does not terminate the task based on an inactive interval.
Instructs DC/UCF to save the current terminal-screen contents associated with a task before writing the data stream associated with an immediate-write request.
The save status for a task is initially established at system generation time by the SAVE parameter of the TASK statement.
Instructs DC/UCF not to save the current terminal-screen contents associated with a task before writing the data stream associated with an immediate-write request.
This save status for a task is initially established at system generation time by the NOSAVE parameter of the TASK statement.
Varies the resource timeout interval for the specified task.
The resource timeout interval is the amount of time after a pseudo-conversational task terminates that the logical terminal task is allowed to retain resources acquired by the task. When the resource interval is reached, DC/UCF invokes the resource timeout program.
The new resource timeout interval, in the range 0 through 32,767, measured in real-time seconds.
Varies the resource timeout interval for the specified task to the value established at system generation time by the RESOURCE TIMEOUT INTERVAL parameter of the SYSTEM or TASK statement.
Information specified at the TASK level overrides information specified at the system level.
Instructs DC/UCF not to delete resources for the task based on a timeout interval.
Specifies the name of the program DC/UCF is to invoke when the resource timeout interval expires.
The resource timeout program processes (for example, deletes) resources held by the logical terminal on which the task executed.
The name of a program included in the system definition.
The version number of the program; an integer in the range 1 through 9,999.
The default is 1.
Varies the resource timeout program to the program specified at system generation time on the RESOURCE TIMEOUT parameter of the SYSTEM or TASK statement.
Information specified at the task level overrides information specified at the system level.
Specifies that programs that run under the task must reside below 16 megabytes and must use 24-bit addressing.
The location of a task is initially established at system generation time by the LOCATION parameter of the TASK statement.
Specifies that programs that run under the task can reside anywhere in the DC/UCF region and can use either 24-bit or XA 31-bit addressing.
Varies the maximum number of concurrently active threads allowed for the specified task.
The maximum number of concurrently active threads allowed for a task is initially established at system generation time by the MAXIMUM CONCURRENT THREADS parameter of the TASK statement.
An integer in the range 1 through 32,767.
Specifies that DC/UCF does not limit the number of concurrently active threads for the task.
Varies the storage limit for the task, as described in Usage.
Varies the lock limit for the task, as described in Usage.
Varies the call limit for the task, as described in Usage.
Varies the database I/O limit for the task, as described in Usage.
The new storage, lock, call, or database I/O limit for the task. The table located in Usage provides valid resource limits for each type of task thread.
Resource limits for a task are initially established at system generation time by the LIMIT parameter of the SYSTEM or TASK statement.
Varies the storage, lock, call, or database I/O limit for the task to the value established at system generation time by the LIMIT FOR ONLINE TASKS parameter of the SYSTEM statement.
Disables limits. When OFF is specified for a resource, DC/UCF does not limit the task's use of the resource.
Varies the external wait setting for a task.
The new external wait time in seconds. The value must be in the range 0 through 32,767. A value of 0 is equivalent to specifying SYSTEM.
Indicates that the external wait time for a task is to be set to the value established for the system.
Indicates that there is no limit to the length of time that the system waits for an external user session to issue a database request.
Varies the quiesce wait time for a task.
Specifies the new quiesce wait time in wall clock seconds. The value must be in the range 0 through 32,767. A value of 0 is equivalent to specifying SYSTEM
Specifies that the quiesce wait time for the task is determined by the quiesce wait setting in effect for the system.
Specifies that the task is not to be terminated due to a quiesce wait.
Specifies that the task is not to wait for a quiesce operation to terminate. Instead an error is returned to the application program indicating that an area is unavailable. For navigational DML applications, this results in an error status of 'xx66'.
Specifies options that control commit behavior. These options apply only to commit operations in which the database session remains active.
Specifies that the commit behavior for the task should default to that specified for the system.
Specifies that a COMT journal record should be written.
Specifies that an ENDJ journal record should be written.
NEW ID Specifies that a new local transaction ID should be assigned to the next transaction started by the database session.
RETain ID Specifies that the current local transaction ID should be assigned to the next transaction started by the database session.
Specifies options that control rollback behavior. These options apply only to rollback operations in which the database session remains active.
Specifies that the rollback behavior for the task should default to that specified for the system.
Specifies that the current local transaction ID should be assigned to the next transaction started by the database session.
Specifies that a new local transaction ID should be assigned to the next transaction started by the database session.
Specifies the type of snap dump or photo snap to write to the DC/UCF log file.
Valid values are the following:
Specifies whether to write a system snap dump for the specified task. A system snap dump writes a formatted display of the resources allocated to all active tasks.
ON Enables the writing of a system snap dump.
OFF Disables the writing of a system snap dump.
Specifies whether to write a system photo snap for the specified task. A system photo snap provides a summary of resources for all active tasks.
ON Enables the writing of a system photo snap.
OFF Disables the writing of a system photo snap.
Specifies whether to write a task snap dump for the specified task. A task snap dump writes a formatted display of the resources allocated to the task being snapped.
ON Enables the writing of a task snap dump.
OFF Disables the writing of a task snap dump.
Specifies whether to write a task photo snap for the specified task. A task photo snap provides a summary of the resources for the task being snapped.
ON Enables the writing of a task photo snap.
OFF Disables the writing of a task photo snap.
Specifies the total snaps allowed for the specified task. When the snap limit is reached, snaps are disabled for the task. The maximum snap limit value is 999.
Specifies the setting for the transaction sharing option.
Specifies that transaction sharing should be initially enabled for any task of this type.
Specifies that transaction sharing should be initially disabled for any task of this type.
Specifies that the transaction sharing option for a task of this type is based on the system default established in the sysgen or by a DCMT VARY TRANSACTION SHARING command.
