Parameters, currently part of the partitioning scheme, are
listed within the next paragraph, together with the old and new
way of assigning values. A change in the command set has become
necessary to reflect the new schema. Each of those parameters
may be set to different values for different, so called
dCache sections. The only
section, existing without being created, is
the default section. With the pre 1.7.0
command set, only the default section can be
manipulated. With the new commmand set, all
sections can be created or modified. If only
a subset of parameters of a non default
section is defined, the residual parameters of this
section are inherited from the default
section. So, changing a parameter in the
default section, will change the same
parameter of all other sections for which this particular
parameter has not been overwritten.
Commands related to dCache partitioning :
pm set [<sectionName>] -<parameterName>[=<value>|off] sets a parameter <parameterName> to a new value. If <sectionName> is omitted, the
defaultsection is used. If <sectionName> doesn’t exist yet, it is (silently) created. If a parameter is set tooffthis parameter is no longer overwritten and is inherited from thedefaultsection. Theoffdoesn’t make sense for thedefaultsection.pm ls [-l] [<sectionName>] lists a single or all sections. Except for the
default, only those parameters are shown which are explicitly set. Parameters, not shown, are inherited from thedefaultsection.pm destroy <sectionName> destroys a section.
The top menu of the PoolManager configuration web pages
points to a page summerizing the section status of the
system. This is essentially the content of the pm ls
-l.
