product you accessed explicitly from TMON for DBCTL, you return
to TMON for DBCTL.

Using Implicit Pass-Through

Implicit access is product-to-product communication initiated
automatically by the system. It occurs only between address spaces
of the same product (for example, TMON for CICS to TMON for
CICS) and can occur between products in the same or different
processor complexes. It does not occur between different products
(for example, TMON for CICS to TMON for MVS).

Implicit access is initiated differently for Landmark
PerformanceWorks MVS products. The following table indicates
how to initiate implicit access for each product.

Product

Implicit Access

TMON for CICS

Initiated by selecting a remote CICS address space
from the Job Selection List screen and a Primary
Selection Menu option other than PERFORMANCE
MONITOR, PASS-THROUGH SESSIONS, or SYSTEM
ADMINISTRATION. This allows you to monitor the
performance of another CICS address space. To
ensure that a remote CICS address space appears on
the Job Selection List screen, the following conditions
must be met: The remote Cross System Monitor
applid must be defined on the Remote Sessions
Directory and CICS Job Definitions screens, and
JOBSCAN CONTROL=N must be specified on the
CICS Job Definitions screen.

TMON for DB2

Initiated by selecting a remote DB2 subsystem on the
DB2 Subsystem Selection screen and a Primary Menu
option other than MONITOR CONTROLS or
ADVANCED FUNCTIONS. You also can invoke
implicit access in TMON for DB2 when you
cursor-select a data field associated with a remote
DB2 subsystem from the DB2 Subsystem Selection
screen.

TMON for DBCTL

Initiated by selecting a remote DBCTL subsystem on
the DBCTL Subsystem Selection screen and a Primary
Menu option other than MONITOR CONTROLS or
ADVANCED FUNCTIONS. You also can invoke
implicit access in TMON for DBCTL when you
cursor-select a data field associated with a remote
DBCTL subsystem from the DBCTL Subsystem
Selection screen.

TMON for MQSeries Initiated by selecting a queue manager being

monitored by a TMON for MQSeries running on
another MVS image and a Primary Menu option other
than MONITOR CONTROLS or ADVANCED
FUNCTIONS.

TMON for MVS

Initiated in only one instance: when you select an MVS
system on another processor complex on the System
Selection Menu.
