corosync-objctl − Configure objects in the Object Database
corosync-objctl [−b] [−c|−w|−d|−a|−t−h] <OBJECT-SPEC>...
corosync-objctl is used to configure objects within the object database at runtime.
There are two types of entities
Objects and Key=Value pairs
Objects
Objects are container like entities that can hold other entities. They are specified as "objectA"."objectB". An example is logging.logger.
Key=Value pairs
These are the entities that actually hold values (read database "fields"). They are specified as object.key=value or just object.key if you are reading.
|
-c |
Create a new object. | ||
|
-d |
Delete an existing object. | ||
|
-w |
Use this option when you want to write a new value to a key. | ||
|
-a |
Display all values currently available. | ||
|
-t |
Track changes to an object and it’s children. As changes are made to the object they are printed out. this is kind of like a "tail -f" for the object database. | ||
|
-h |
Print basic usage. | ||
|
-b |
Display binary values in BASH backslash escape sequences format. |
Print the objOne object (shouldn’t exist yet).
$ corosync-objctl objOne
Create the objOne object.
$ corosync-objctl -c objOne
Print the objOne object (empty).
$ corosync-objctl objOne
objOne
Write two new keys to the objOne object.
$ corosync-objctl -w objOne.max=3000 objOne.min=100
Print the objOne object (with the two new keys).
$ corosync-objctl objOne
objOne.min=100
objOne.max=3000
Delete the objOne.min key
$ corosync-objctl -d objOne.min=100
Prove that is gone.
$ corosync-objctl objOne
objOne.max=3000
Delete the whole objOne object.
$ corosync-objctl -d objOne
Prove that is gone.
$ corosync-objctl objOne
