Much of CICSPlex® SM’s activity is time dependent. For example, you can specify
that a monitor definition or an analysis definition is to be active during a particular time period. CICSPlex SM does
not require every MAS in a single CICSplex to be running in the same time zone,
and so must be able to accommodate any time-zone differences between entities.
Therefore:
- Whenever you create a time-period definition (using the CICSPlex SM PERIODEF
view), you must specify a time zone in the definition.For example, you could create a time-period definition called "MORNING" for the hours 0800 through 1159 Eastern standard
time.
- You must specify a time zone for each CMAS in its data-repository initialization
job, EYU9XDUT. A permanent change to the CMAS time-zone value can be made,
even while the CMAS is running, via the CICSPlex SM user interface.
- A time zone must be established for each managed CICS® system. When
you define a CICS system to CICSPlex SM, you can specify the time zone in which the system
is running. Alternatively, if you don’t specify a time zone in the CICS system definition, the CICS system is assumed to be running in the
time zone that is the default for the CMAS to which it connects. You are recommended
to allow the time zone of a managed CICS system to default to that of its CMAS.
The time zone of a managed CICS system can be altered subsequently while
the CICS system is running. Any change made in this way lasts for the lifetime
of the CICS system, or until it is next changed, whichever is sooner.
- A time zone must be specified for every CICSplex when it is first defined.
This time zone is used by the CICSPlex SM monitor function to determine the actual
time at which the monitor interval for the CICSplex expires. The CICSplex time zone
can be altered via the CICSPlex SM end-user interface.
Time zones are specified using single-character codes in the range B through
Z. For example, code "S" represents Mountain Standard Time, code "T" represents Central Standard Time, and code "C" represents Eastern
Europe time. A complete list of the codes can be found in CICSPlex SM Administration. CICSPlex SM allows
offsets (known as "time zone adjustments") in the range 0 through 59
minutes to be specified to accommodate regions that are not running in the
standard time zones. Also, daylight saving time can be specified.
Because multiple CICSPlex SM entities require a time zone to be specified, there
is obvious potential for "conflicting" time-zones to be specified. For
example, it is quite possible that a CMAS and a MAS in the same CICSplex could
be in different time zones. CICSPlex SM always honors the time zone of the MAS.
For example, if:
- The time-period definition time zone is S
and
and
time zone C is used by the MAS, and the CMAS makes any necessary adjustments
between time zones B, C, and S to ensure that the time zone is honored.
