The implicitLocking Attribute

The <simpleSteps> element has been modified to accept a new attribute, called implicitLocking. Attributes for the <simpleSteps> element are now as follows:

executionMode

An optional attribute already part of the N1 Service Provisioning System, that indicates whether the contained steps should be executed in a series or in parallel over the target hosts. The legal values are PARALLEL and SERIES. If the executionMode attribute is omitted, the value is PARALLEL.

limitToHostSet

An optional attribute already part of the N1 Service Provisioning System, that specifies the name of the host set that contains the hosts that can be valid targets for this plan. If this attribute is omitted, all hosts can be valid targets. Otherwise, the targets that you specify must be a subset of the hosts that are contained in the named host set.

If the targets include a host that is not contained in the named host set, the plan issues a runtime error. If you specify a name that does not correspond to an existing supported host set, the plan also issues a runtime error. If the specified host set is defined by a plug-in, the pluginName must be prefixed to the host set name, such as pluginName#hostSetName. These plan runtime errors are reported during validation before the preflight starts.

implicitLocking

A new attribute for the release of N1 Service Provisioning System. The implicitLocking attribute indicates what type of host locking to use for the contained steps. If the implicitLocking attribute is omitted, the value is set to TRUE, so no other plans or subplans can be executed against that host until the steps enclosed in the <simpleSteps> element have completed. If a plan is retargeted to another host, this retargeted host is also locked until the completion of the retargeted step.

If the implicitLocking attribute is set to false, the browser interface displays the following new message for a retarget step:

connect and check hosts

If the implicitLocking attribute is set to FALSE, no hosts are locked by a plan during the completion of the <simpleSteps> element, including retargeted hosts, unless a lockHost step is used.
