8.3.4. Reloading the ACL

You can reload the ACL without restarting the broker using a QMF method, either using qpid-tool or from program code.

Reload the ACL using qpid-tool

You need to use qpid-tool with a account with sufficient privileges to reload the ACL.
  1. Start qpid-tool: 
    $ qpid-tool admin/mysecretpassword@mybroker:5672
Management Tool for QPID
qpid:
  2. Check the ACL list to obtain the object ID: 
    qpid: list acl
Object Summary:
    ID   Created   Destroyed  Index
    =================================
    103  12:57:41  -          116
  3. Optionally, you can examine the ACL: 
    qpid: show 103
Object of type: org.apache.qpid.acl:acl:_data(23510fc1-dc51-a952-39c2-e18475c1677e)
    Attribute              103
    =================================================
    brokerRef              116
    policyFile             /tmp/reload.acl
    enforcingAcl           True
    transferAcl            False
    lastAclLoad            Tue Oct 30 12:57:41 2012
    maxConnectionsPerIp    0
    maxConnectionsPerUser  0
    maxQueuesPerUser       0
    aclDenyCount           0
    connectionDenyCount    0
    queueQuotaDenyCount    0
  4. To reload the ACL, call the reload method of the ACL object: 
    qpid: call 103 reloadACLFile
qpid: OK (0) - {}

Reload ACL from program code

The broker ACL can be reloaded at runtime by calling a QMF method.
The following code calls the appropriate QMF method to reload the ACL:
Python
import qmf.console
qmf = qmf.console.Session()
qmf_broker = qmf.addBroker('localhost:5672')
acl = qmf.getObjects(_class="acl")[0]
result = acl.reloadACLFile()
print result
Note that the server must be started with ACL enabled for the reload operation to succeed.
