DB2 FOR LUW / DB2FORLUW / A50 - DB2

On the affinity feature, even for the very first connection, 
DB2 client/driver uses affnity list including a member list in 
which members are defined in alternate server list. 
 
  For example, if db2dsdriver.cfg includes the following 
elements about affinity feature, the small memory leaks in db2 
Client/Driver.  And this memory leak occurs even if 
clientaffinitydefined element is not included or even on the 
cached affinity member list from the earlier connection. 
 
  A sample of db2dsdriver.cfg 
 
       <acr> 
          .... 
          <alternateserverlist> 
             <server name="member1" hostname="localhost" 
port="31126"/> 
             <server name="member2" hostname="localhost" 
port="31126"/> 
          </alternateserverlist> 
          <affinitylist> 
             <list name="list1" serverorder="member1,member2"/> 
             <list name="list2" serverorder="member2,member1"/> 
          </affinitylist> 
          <clientaffinitydefined> 
            <client name="client1" hostname="localhost" 
listname="list1"/> 
          </clientaffinitydefined> 
       </acr>
