3.5 Entering Partition Commands
3.5 Entering Partition Commands
Partitions can be managed by issuing partition commands directed at the
required partition after they are created. Partition commands can be entered in
one of two ways:
• A command line processed by the RTR command line interface, for example
RTR> SET PARTITION
• Programmed using
rtr_set_info( )
Enter partition commands on the backend where the partition is located. Note
that commands that affect a partition state only take effect once the first server
joins a partition. Errors encountered at that time will appear as log file entries.
Using partition commands to change the state of the system causes a log file
entry.
3.5.1 Command Line Usage
Partition management in the RTR command language is implemented with the
following command set:
•
RTR> CREATE PARTITION
•
RTR> SET PARTITION
•
RTR> DELETE PARTITION
The name of the facility in which the partition resides may be specified with the
/FACILITY command line qualifier, or as a colon-separated prefix to the partition
name (for example Facility1:Partition1). Detailed descriptions of the command
syntax are given in the Command Line Reference section of this manual, and are
summarized in the discussions below. Examples in the following sections use a
partition name of Partition1 in the facility name of Facility1.
3.5.2 Programmed Partition Management
Partition commands are programmed using
rtr_set_info( )
. Usage of the
arguments are as follows:
•
pchannel
- Supplies the address of a
rtr_channel_t
to receive the channel
opened in the event of a successful call.
• Flags must be
RTR_NO_FLAGS
• Verb must be the value
verb_set
(from the enumeration rtr_verb_t)
• Object must be
rtr_partition_object
•
select_qualifiers
should identify the facility and partition, by name, for
example:
rtr_qualifier_value_t select_qualifiers[ 3 ];
select_qualifiers[ 0 ].qv_qualifier = rtr_facility_name;
select_qualifiers[ 0 ].qv_value = "your_facility_name_here";
select_qualifiers[ 1 ].qv_qualifier = rtr_partition_name;
select_qualifiers[ 1 ].qv_value = "your_partition_name_here";
select_qualifiers[ 2 ].qv_qualifier = rtr_qualifiers_end;
select_qualifiers[ 2 ].qv_value = NULL;
• The
set_qualifier
list expresses the required change in partition behaviour
or characteristic.
