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
default
section is used. If <sectionName> doesn’t exist yet, it is (silently) created. If a parameter is set tooff
this parameter is no longer overwritten and is inherited from thedefault
section. Theoff
doesn’t make sense for thedefault
section.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 thedefault
section.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.
