corosync-objctl(8)
Configure objects in the Object Database
SYNOPSIS
corosync-objctl [-b] [-c|-w|-d|-a|-t-h] <OBJECT-SPEC>...
DESCRIPTION
corosync-objctl
is used to configure objects within the object database at runtime.
OBJECT-SPEC
- 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.
OPTIONS
- -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.
EXAMPLES
- 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
