NimbostratusToggle Pool Members iControl java API
I am trying to toggle pool members in a local traffic pool to control the traffic to one or other ip. Defined two pool members through BigIP Console:
10.20.30.101:15001
10.20.30.105:15001
Initial State : 10.20.30.101:15001 is enabled and 10.20.30.105:15001 is disabled.
Now trying to disable 10.20.30.101:15001 and enable 10.20.30.105:15001.
I am setting pool memeber session status, session state to achieve this. But when verified back in console, no changes takes place. Any help is greatly appreciated:
Here is the java code:
LocalLBPoolPortType t = myi.getLocalLBPool();
// retrieve the entire list of pools for this load balancer
String[] poolList = t.get_list();
LocalLBPoolMemberPortType poolMember = myi.getLocalLBPoolMember();
LocalLBPoolMemberMemberSessionStatus[][] sessionstatus = poolMember.get_session_status(chudPoolList);
LocalLBPoolMemberMemberSessionState[][] sessionstate = poolMember.get_session_enabled_state(chudPoolList);
LocalLBPoolMemberMemberMonitorStatus[][] monitorstatus = poolMember.get_monitor_status(chudPoolList);
for (int j = 0; j < sessionstate.length; j++)
{
for (int k = 0; k < sessionstate[j].length; k++)
{
if (sessionstate[j][k].getSession_state().equals(CommonEnabledState.STATE_ENABLED))
{
System.out.println("Current Session State.." + sessionstate[j][k].getMember().getPort() + ".." + sessionstate[j][k].getSession_state().getValue());
sessionstate[j][k].setSession_state(CommonEnabledState.STATE_DISABLED);
System.out.println("Updated Session State.." + sessionstate[j][k].getMember().getPort() + ".." + sessionstate[j][k].getSession_state().getValue());
System.out.println("Current Session Status.." + sessionstatus[j][k].getMember().getPort() + ".." + sessionstatus[j][k].getSession_status().getValue());
sessionstatus[j][k].setSession_status(LocalLBSessionStatus.SESSION_STATUS_DISABLED);
System.out.println("Updated Session Status.." + sessionstatus[j][k].getMember().getPort() + ".." + sessionstatus[j][k].getSession_status().getValue());
}
else
if (sessionstate[j][k].getSession_state().equals(CommonEnabledState.STATE_DISABLED))
{
System.out.println("Current Session State.." + sessionstate[j][k].getMember().getPort() + ".." + sessionstate[j][k].getSession_state().getValue());
sessionstate[j][k].setSession_state(CommonEnabledState.STATE_ENABLED);
System.out.println("Updated Session State.." + sessionstate[j][k].getMember().getPort() + ".." + sessionstate[j][k].getSession_state().getValue());
System.out.println("Current Session Status.." + sessionstatus[j][k].getMember().getPort() + ".." + sessionstatus[j][k].getSession_status().getValue());
sessionstatus[j][k].setSession_status(LocalLBSessionStatus.SESSION_STATUS_ENABLED);
System.out.println("Updated Session Status.." + sessionstatus[j][k].getMember().getPort() + ".." + sessionstatus[j][k].getSession_status().getValue());
}
}
}
- You are querying the values and returning them into a local structure. You are then setting values in the local structure but I don't see anywhere you are making the call to "set" the values on the existing objects. Local structures have no connection to the BIG-IP unless you make a "set" method call to assign them. If you want to see the methods needed, you can check out the "togglePoolMember" perl script in the CodeShare

The relevant methods are set_session_enabled_state and/or set_monitor_state (depending on how you want it set). A more detailed sample on those two methods can be found here:http://devcentral.f5.com/wiki/default.aspx/iControl/PsServerControl.html

Hope this helps...

Prasad_81758Thanks Joe for pointing out. Made the changes and working good. Here is the complete method in case someone needs in future.
public static void resetSessionState(String un, String pwd, String ip) {
String[] chudPoolList = new String[1];
chudPoolList[0] = "stage-live";
try {
Interfaces myi = new Interfaces();
myi.initialize("lbpoc", un, pwd);
// retrieve the entire list of pools for this load balancer
LocalLBPoolMemberPortType poolMember = myi.getLocalLBPoolMember();
LocalLBPoolMemberMemberSessionState[][] sessionstate = poolMember.get_session_enabled_state(chudPoolList);
LocalLBPoolMemberMemberSessionState[][] newSessionState = new LocalLBPoolMemberMemberSessionState[1][2];
System.out.println("\nSwitching the Local Pool....");
for (int j = 0; j < sessionstate.length; j++)
{
for (int k = 0; k < sessionstate[j].length; k++)
{
if (sessionstate[j][k].getSession_state().equals(CommonEnabledState.STATE_ENABLED))
{
CommonIPPortDefinition portDefn1 = new CommonIPPortDefinition();
portDefn1.setAddress(sessionstate[j][k].getMember().getAddress());
portDefn1.setPort(sessionstate[j][k].getMember().getPort());
newSessionState[j][k] = new LocalLBPoolMemberMemberSessionState();
newSessionState[j][k].setMember(portDefn1);
newSessionState[j][k].setSession_state(CommonEnabledState.STATE_DISABLED);
}
else
if (sessionstate[j][k].getSession_state().equals(CommonEnabledState.STATE_DISABLED))
{
CommonIPPortDefinition portDefn1 = new CommonIPPortDefinition();
portDefn1.setAddress(sessionstate[j][k].getMember().getAddress());
portDefn1.setPort(sessionstate[j][k].getMember().getPort());
newSessionState[j][k] = new LocalLBPoolMemberMemberSessionState();
newSessionState[j][k].setMember(portDefn1);
newSessionState[j][k].setSession_state(CommonEnabledState.STATE_ENABLED);
}
}
}
poolMember.set_session_enabled_state(chudPoolList, newSessionState);
} catch (Exception e) {
System.out.println(" **** ERROR ****: " + e.getMessage());
e.printStackTrace();
}
System.out.println("\nSwitching the Local Pool COMPLETE....");
}
