Error description

• v3.9-fp1, platform independent.
  
  Poller continues to poll old accessIPAddress instead of new IP
  when the old IpAddress does not exist either Model or in NCIM.
  
  Replication steps for lab:
  1) Configure discovery to use seed file based discovery with
  single device with feedback turned off
  
  seed file content:
  #cat filebased.txt
  172.30.229.1, abc.ibm.com
  
  2) Configure DNS such that, it picks name defined under seed
  file.
  $ cat DiscoDNSHelperSchema.FILEBASED.cfg
  create database DNSHelper;
  create table DNSHelper.configuration
  (
          m_NumThreads            int,
          m_MethodList            list type text
  );
  
  insert into DNSHelper.configuration
  (
          m_MethodList,
          m_NumThreads
  )
  values
  (
          ['HostsFile'],
          10
  );
  create table DNSHelper.methods
  (
          m_MethodName            text not null primary key,
          m_MethodType            int,
          m_NameServerAddr                text,
          m_NameDomain            text,
          m_NameDomainList                list type text,
          m_FileName              text,
          m_FileOrder             int,
          m_TimeOut               int,
  
          unique(m_MethodName)
  );
  
  insert into DNSHelper.methods
  (
          m_MethodName,
          m_MethodType,
          m_FileName,
          m_FileOrder,
          m_NameDomain
  )
  values
  (
          "HostsFile",
          2,
          "/opt/IBM/tivoli/netcool/etc/precision/filebased.txt",
          1,
          ''
  );
  
  3) After completion of discovery - you could see, the device is
  named with 'abc.ibm.com'
  4) Modify seed file with different ip, but name being same.
  172.30.229.2,abc.ibm.com
  5) Kick off full discovery
  6) Upon completion of discovery, verify in Disco, Model & NCIM
  has "172.30.229.2" with device naming being 'abc.ibm.com'
  
  7) The poller OQL still shows old IP instead of new IP. Below is
  excerpt from 'monitors.current'
  {
          MAINNODEENTITYID=4788748;
          MAINNODEADDRESS='172.30.229.1';
          MAINNODEENTITYNAME='abc.ibm.com';
          ENTITYCLASS='Cisco36xx';
          LINGERTIME=3;
          CHASSISMANAGED=NULL;
          ENTITYID=4788748;

          ENTITYTYPE=1;

          LASTPOLLTIME='2012-07-23 12:08:45';
          LASTPOLLINTERVAL=0;
          LASTPOLLFAILURE='1969-12-31 19:00:00';
          TEMPLATEID=1;
          TEMPLATENAME='Default Chassis Ping';
          POLICYID=344;
          POLICYNAME='Default Chassis Ping';
          CURRENTTIME='2012-07-23 12:10:15';
  }
  

Local fix

• Restart Poller.
