SQL REPLICATION CAPTURE PROGRAM CAN GET ERROR READING THE DB2 LOG FILES: SQL -2650, RC 8 |
| product: |
DB2 FOR LUW / DB2FORLUW / 910 - DB2 |
| Problem description: |
During replication capture, the following error might be raised
if LOGFILSZ configuration parameter was changed:
In db2diag.log:
2010-04-03-01.19.43.245665+120 I965554A563 LEVEL: Error
PID : 9348 TID : 283 PROC : db2sysc

sqlp_AsyncLogReadAPI, probe:210
DATA #1 : String, 123 bytes
Error: sqlcode -2650, rc 8, hflag2LsnReuse 0
The capture log will report :
2010-04-03-01.19.43.255329 <logrd::readTheLog> ASN0005E CAPTURE
"ASN" :
"WorkerThread". The Capture program encountered an error when
reading
the DB2 log. The log sequence number is
"0000:0000:0774:E9D8:9453", the
SQLCODE is "-2650", and the reason code is "piStartLSN
db2ReadLog 5".
The main reason for this issue is a reported log file size
modification during database recovery in the db2diag.log which
is most likely to happen in an HADR context:
2010-03-31-23.53.15.583475+120 I41717A560 LEVEL: Info

EDUID : 269 EDUNAME: db2redom (HRS) 0
FUNCTION: DB2 UDB, recovery manager,
sqlpChangeLogFileSizeDuringRecovery, probe:10
DATA #1 : <preformatted>
Log file size is changing during database recovery. Old:
dbcb->logfhdr.logsize 10000, New: Extent 201260, ExtSize 25000,
firstlsn 07717D6B8000
This log file size modification being applied through database
recovery can have DB2 mis-calculate the log file record for a
given LSN since the initial log file size was picked up earlier
during the startup of the instance. This APAR will make so that
the initial log file size is reset correctly in this particular
case. |

| Local Fix: |
Stop and start the instance after this
"sqlpChangeLogFileSizeDuringRecovery, probe:10" is captured in
the db2diag.log will set the initial log file size to the proper
value. |
