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
