Building a Continental Cluster
Forcing a Package to Start
Chapter 5 255
Forcing a Package to Start
The cmforceconcl command is used to force a ContinentalClusters
package to start even if the status of a remote package in the recovery
group is unknown. This command is used as a prefix to a cmrunpkg and
cmmodpkg command.
Under normal circumstances, ContinentalClusters will not allow a
package to start in the recovery cluster unless it can determine that the
package is not running in the primary cluster. In some cases,
communication between the two clusters may be lost, and you may need
to start the package on the recovery cluster anyway. To do this, you can
use the cmforeconcl command. The command is used along with a
cmrunkpg or cmmodpkg command, as in the following example:
# cmforceconcl cmrunpkg -n node3 Pkg1
WARNING When using this command, it is your responsibility to ensure
that the other cluster is not running the package. Failure to do
this may result in the package running in both clusters, which
will cause data corruption.
