COSINI Command – Starting Control-O/COSMOS

Note: As of version 6.1.00, this command uses a predefined prefix in place of the original "COS" prefix. For more information about these prefixes, see Supporting Multiple Control-O/COSMOS Instances.

Use this command to start Control-O/COSMOS.

The following Shout messages are issued in response to the COSINI command:

Figure 15 COSINI Shout Messages

COSMOS -     THE FOLLOWING STARTING OPTIONS ARE AVAILABLE:

COSMOS -     1 - DESIRED = UP

COSMOS -     2 - DESIRED = DOWN

COSMOS -     3 - DESIRED = CURRENT (AND SET MODE FORCE_OK)

COSMOS -     4 - DESIRED = SOURCE DATABASE DESIRED COLUMN

COSMOS -     5 - DESIRED = SOURCE DATABASE ATIPL COLUMN

COSMOS -     6 - DESIRED = SOURCE DATABASE NOTIPL COLUMN

nn CONTROL-O/COSMOS - SELECT ONE OPTION

These messages indicate different options that can be used to determine startup status for Control-O/COSMOS-controlled objects.

The option that is recommended depends on whether Control-O/COSMOS will be responsible for starting other resources (objects) in the system.

• If Control-O/COSMOS is started at IPL, option 5 is recommended. This option causes the desired status to be set according to the ATIPL column in the Source Object database.
• If Control-O/COSMOS is started without an IPL, option 3 is recommended. Option 3 sets each object’s mode to FORCE_OK.

  When a Control-O/COSMOS Object database is initialized, the current status of each object is set to UNKNOWN. The next time Control-O/COSMOS scans the Object database, a rule is triggered to determine the current status.

• If startup option 3 (mode FORCE_OK) was specified at Control-O/COSMOS startup, the desired status is modified to match the new current status. After current and desired statuses are set, objects can be assigned a mode of FREE to transfer control of the object status to Control-O/COSMOS.
• If a startup option other than 3 was specified, the desired status for each object is set according to the specified option. The next time Control-O/COSMOS scans the Object database, Control-O/COSMOS takes steps to ensure that objects are brought to their desired statuses.

Note: The default startup option supplied with Control-O/COSMOS is option 3 (that is, if no option is specified for 30 seconds this option is automatically implemented). This default can be modified (in the COSINIT0 rule) to conform with your site’s requirements.
