delete_pool not working

Nope, that should work. Could you post a snippet of your code where you are defining the parameters and the method call so I can make sure the pool name is getting passed in properly?

I believe the pool name is getting passed in properly because if I try to delete a pool that does not exist, then I get an error stating that.

 

 

 

iControl.LocalLBPoolBindingStub lblpool =

 

(iControl.LocalLBPoolBindingStub) new iControl.LocalLBPoolLocator

 

().getLocalLBPoolPort(new java.net.URL(endpoint));

 

 

lblpool.setTimeout(IDLE_TIMEOUT);

 

 

String poolName =

 

ActionRequestUtils.resolveStringParam(anActionRequest, "poolName");

 

 

// The following line is how you create an empty pool without members.

 

iControl.CommonIPPortDefinition[][] member =

 

new iControl.CommonIPPortDefinition[1][0];

 

iControl.LocalLBLBMethod lb_method =

 

iControl.LocalLBLBMethod.LB_METHOD_ROUND_ROBIN;

 

iControl.LocalLBLBMethod[] lbMethods =

 

new iControl.LocalLBLBMethod[]{lb_method};

 

 

if (create) {

 

lblpool.create(new String[]{poolName}, lbMethods, member);

 

 

// Now set a default monitor association

 

iControl.LocalLBMonitorRule monitorRule = new iControl.LocalLBMonitorRule();

 

monitorRule.setMonitor_templates(new String[]{"gateway_icmp"});

 

// monitorRule.setQuorum(quorum);

 

monitorRule.setType(LocalLBMonitorRuleType.MONITOR_RULE_TYPE_SINGLE);

 

iControl.LocalLBPoolMonitorAssociation monitorAssociation = new

 

iControl.LocalLBPoolMonitorAssociation(); monitorAssociation.setPool_name

 

(poolName);

 

monitorAssociation.setMonitor_rule(monitorRule);

 

iControl.LocalLBPoolMonitorAssociation[] monitorAssociations = new

 

iControl.LocalLBPoolMonitorAssociation[]{monitorAssociation};

 

lblpool.set_monitor_association(monitorAssociations);

 

} else

 

lblpool.delete_pool(new String[]{poolName});

 

}

 

 

removed

is the pool referenced by a virtual or an iRule? That would prevent it from being deleted.

Excuse my ignorance, but I have only been working with an F5 now for a total of about 6 days. I use the following code to create the pool in the first place. I am setting a LocalLBMethod and a LocalLBMonitorRule. Do I need to somehow unlink/delete them first?

 

 

 

// The following line is how you create an empty pool without members.

 

iControl.CommonIPPortDefinition[][] member =

 

new iControl.CommonIPPortDefinition[1][0];

 

 

iControl.LocalLBLBMethod lb_method =

 

iControl.LocalLBLBMethod.LB_METHOD_ROUND_ROBIN;

 

iControl.LocalLBLBMethod[] lbMethods = new iControl.LocalLBLBMethod[]{lb_method};

 

 

lblpool.create(new String[]{poolName}, lbMethods, member);

 

 

// Now set a default monitor association

 

iControl.LocalLBMonitorRule monitorRule = new iControl.LocalLBMonitorRule();

 

monitorRule.setMonitor_templates(new String[]{"gateway_icmp"});

 

 

monitorRule.setType(LocalLBMonitorRuleType.MONITOR_RULE_TYPE_SINGLE);

 

iControl.LocalLBPoolMonitorAssociation monitorAssociation =

 

new iControl.LocalLBPoolMonitorAssociation();

 

monitorAssociation.setPool_name(poolName);

 

monitorAssociation.setMonitor_rule(monitorRule);

 

iControl.LocalLBPoolMonitorAssociation[] monitorAssociations =

 

new iControl.LocalLBPoolMonitorAssociation[]{monitorAssociation};

 

lblpool.set_monitor_association(monitorAssociations);

You might want to try to call lblpool.remove_monitor_association(new String[]{poolName}); before the call to delete pool to see if that clears up the associations.

Thanks, that did it. It will take me a little bit to get the hang of the F5 APIs.

Is there any sample Java code that sets up and tears down a pool and pool members? It would save me a lot of questions.

I haven't done much with Java on the samples front, but there should be something in the CodeShare (http://devcentral.f5.com/wiki/iControl.CodeShare.ashx) that will help you in the right direction.

Sorry Joe, but not much there. I am going to have to look outside of DevCentral.

 

I also wanted to mention as a newbie, that the F5 documentation

 

 

https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/LTM_config_guide_943/ltm_virtual.html

 

 

is not that useful. It describes all of the options, but not how to use them.

 

 

As a newbie I need a step by step tutorial as how to get the blooming F5 up and running in the first place. I found the following example that helped me to finally get my first load balancing pool up and running: http://www.dasblinkenlichten.com/?p=495 .
