Tasks Failing at Random in vApp


Article ID: 207695


Updated On:


CA Identity Manager CA Identity Suite


Under a heavier load, the default vApp journal file size may be inadequate.  vApp defaults to 25MB and 2 files.  This KB provides steps on how to set 20 journals of 25MBs. This means about twenty 25mb size journal files will be created at startup. When one file gets full, Jboss uses the next one.

This can cause tasks to run but fail at random times.  It could be different or the same tasks where they work most of the time but sometimes run and sometimes fail. 


Release : 14.2 and 14.3

Component : IdentityMinder(Identity Manager) on Virtual Appliance




You must sudo and create a new management console user.  I create a new "jbossuser".  Create the user needed and password.  Run the commands in bold below.

[[email protected]:9990 /]  /subsystem=messaging/hornetq-server=default/:read-attribute(name=journal-min-files)
    "outcome" => "success",
    "result" => 20


In the last 4 commands you will see we run "/subsystem=messaging/hornetq-server=default/:read-attribute(name=journal-min-files)".  This result with 2.  We then run "/subsystem=messaging/hornetq-server=default/: write-attribute(name=journal-min-files,value=20).  This writes the value to 20Run a reload.   The last command we read the attribute again "/subsystem=messaging/hornetq-server=default/:read-attribute(name=journal-min-files)" where it now returns 20 confirming the change was made. 

If a cluster, this should be done on all nodes.  This should also be done on any backup servers.
