             Summary: LP Bug: 1435462 - phandle not updated on node-down, node-up scenario
                 Key: TRAFODION-1074
                 URL: https://issues.apache.org/jira/browse/TRAFODION-1074
             Project: Apache Trafodion
          Issue Type: Bug
          Components: dtm
            Reporter: Oliver Bucaojit
            Assignee: Oliver Bucaojit
            Priority: Critical
             Fix For: 1.1 (pre-incubation)


Ron and Zalo hit a bug while running node down/up testing.  The issue is that on the node-up, the phandle that the lead TM has for the down'd node does not get updated with the newer process ID.  One of the issues is that it will cause sqstop to hang when the lead tm tries to coordinate shutdown. 

gdb commands used to diagnose problem:
(gdb)  p &gv_tm_info.iv_open_tms[1].iv_phandle._data
$1 = (SB_Int64_Type (*)[8]) 0x6cd260
(gdb)  p gv_tm_info.iv_open_tms[1]
$2 = {iv_phandle = {_data = {3552588194732048672, 0, 0, 0, 4294967296, 12884912361, 0, 4294967296}}, iv_tag = 0, iv_in_use = 1, iv_recov_state = TM_FAIL_RECOV_STATE_INITIAL,
  ip_restartTimerEvent = 0x0}
(gdb) p *(SB_Phandle*)0x6cd260
$3 = {iv_flags = 0, iv_type = 2, iv_vers = 1 '\001', iv_len = 64 '@', iv_name_len = 4 '\004', ia_name = "$TM1", '\000' <repeats 27 times>, iv_nid = 1, iv_pid = 10473,
  iv_verifier = 3, ia_rsv2 = {0, 0, 0}, iv_oid = 1}
(gdb) c

In sqshell -a, down and up node 1

SB_Phandle will still have the older process ID.

On sqstop, the shutdown will get stuck. 

Need to trace through the code to find why this is not being refreshed.
