Control-O/COSMOS Modes

A Control-O/COSMOS mode is specified for each Control-O/COSMOS-controlled object in the Object databases. The Control-O/COSMOS mode determines if the object is handled in a special way (for example, if prerequisites are ignored). For example, a Control-O/COSMOS mode can indicate not to modify an object or not to check prerequisites before an object is modified.

A Control-O/COSMOS mode can be modified using an option in a Control-O/COSMOS screen, or using a Control-O/COSMOS command such as COSDB or COSCMD, described in COSDB Command and COSCMD Command, respectively.

The following modes are available:

Table 12 Control-O/COSMOS Modes

Mode	Description
FREE	Normal Control-O/COSMOS operations are performed on the object.
HELD	Rules are not applied by Control-O/COSMOS to the object. This mode can be used if you need to temporarily disable automation rules that update an object’s status.
	Note: When a held object is assigned a different mode (for example, FREE), its current status is not known and is therefore set to UNKNOWN. The next time Control-O/COSMOS scans the Object database, it generally triggers a Control-O/COSMOS rule that determines the current status of the object.
FORCE_OK	Control-O/COSMOS forces the object’s desired status to take the value of its current status. If the current status is changed, the desired status is modified so that it again matches the current status. When Control-O/COSMOS is started following (rather than during) an IPL, mode FORCE_OK is used to indicate that Control-O/COSMOS uses the current status as a starting point. For more information, see COSINI Command – Starting Control-O/COSMOS.
NOPRE	Control-O/COSMOS does not check prerequisites before looking for a method matching the object’s current and desired status. This mode is useful for temporarily overriding dependencies among computing objects.

A Control-O/COSMOS mode is also specified for each Object database and for the entire Control-O/COSMOS facility.

The mode specified for the Control-O/COSMOS facility has a higher priority than the mode specified for each Object database.

If mode HELD, FORCE_OK or NOPRE is specified for the Control-O/COSMOS facility, this mode overrides the mode specified for each Object database.
If mode FREE is specified for the Control-O/COSMOS facility, the mode specified for each Object database determines the handling of Control-O/COSMOS-controlled objects.
The mode specified for each Object database has a higher priority than the mode specified for each Control-O/COSMOS-controlled object.
If mode HELD, FORCE_OK or NOPRE is specified for the Object database, this mode overrides the mode specified for each object.
If mode FREE is specified for Control-O/COSMOS, and mode FREE is specified for an Object database, objects defined in the database are handled according to the mode specified in each row of that Object database (that is, object-specific mode).

When a mode is specified for all of Control-O/COSMOS or for an Object database, the mode is not changed in each row in the Object databases.
