Status: Closed |
DB2 REORG RECLAIM EXTENTS ON ITC TABLES MIGHT DEADLOCK WITH AN APPLICATION |
| product: |
DB2 FOR LUW / DB2FORLUW / B50 - DB2 |
| Problem description: |
The first application is running a reorg reclaim but is waiting
for a latch:
Application handle = 1
Application status = UOW Executing
Status change time = 01/18/2019
17:10:35.327817
Application code page = 819
Application country/region code = 1
DUOW correlation token =
*LOCAL.db2jkl.190118160509
Application name = db2bp
Application ID =
*LOCAL.db2jkl.190118160509
Sequence number = 00001
Agent process/thread ID = 101
Stack of this EDU:
thread_wait
SQLO_SLATCH_CAS64::getConflictComplex
SQLO_SLATCH_CAS64::getConflict
get
sqldDoCleanupLogEndMovePhase
sqldbPerformItcOlrRowMovement
sqldOnlineTableReorg
sqlrreorg_table
sqlrreorg_sendinfo
sqlerKnownProcedure
The second application is holding that latch but is waiting for
a lock that the
first application has acquired:
Application handle = 2
Application status = Lock-wait
Status change time = 01/18/2019
17:16:02.030054
Application code page = 819
Application country/region code = 1
DUOW correlation token =
192.168.2.1.51249.190118095507
Application name = disp+work
Application ID =
192.168.2.1.51249.190118095507
Sequence number = 00705
Agent process/thread ID = 102
...
ID of agent holding lock = 1
Application ID holding lock =
*LOCAL.db2jkl.190118160509
Lock name =
0x000B000600000001000000006A
Lock attributes = 0x00000000
Release flags = 0x00000000
Lock object type = Inplace Reorg Lock
Lock mode = Share with Intention
Exclusive Lock (SIX)
Lock mode requested = Share Lock (S)
Name of tablespace holding lock = TABLESPACE1
Schema of table holding lock = SAPR3
Name of table holding lock = TABLE1
Data Partition Id of table holding lock = 0
Lock wait start timestamp = 01/18/2019
17:16:02.030055
The second application is running the following stack:
thread_wait
sqloWaitEDUWaitPost
sqlplWaitOnWP
sqlplWaitOnWP
sqlplrq
sqlplrq
sqldOLRScanState
sqldScanOpen
sqldScanOpen
sqlritaSimplePerm
sqlriSectInvoke
sqlriSectInvoke
sqlrr_process_fetch_request
sqlrr_open
sqljsParseRdbAccessed
These two application are waiting for each other. The reorg will
not show any
progress. |
