For RHQ 4.9 - 4.11 installations this migrates data from the metrics_index table into the new metrics_idx table. For 4.12 installations, it migrates data from metrics_cache_index into metrics_idx. The old index tables are deleted after successfully migrating data.

Method Detail

setSession

public void setSession(com.datastax.driver.core.Session session)

Description copied from interface: Step

Invoked prior to Step.execute(). Note that this is the same session used by SchemaManager and it should not be closed.

bind

public void bind(Properties properties)

Description copied from interface: Step

Bind the set of provided properties to the input step. The text should have all the variable to be bound in %variable_name% form.

This method should be called even if no properties are provided because it will throw a runtime exception if the text contains properties that are expected to be bound but the list of variable is either empty or does not contain them.

This method is invoked prior to Step.execute()

Specified by:

Parameters:

properties - properties to bind
