Problem IC68094

Status: Geschlossen |
FUTURE-DATED TIMESTAMPS REPORTED BY THE DEADLOCK MONITOR ON SOLARIS X86-64 |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 950 - DB2 |
| Problembeschreibung: |
On the Solaris 64-bit platform, running on the x86-64
architecture, when using the deadlock event monitor while
running DB2, you might see timestamps that are future-dated,
with respect to the system time, in the formatted event monitor
output.
Example:
select current timestamp from sysibm.sysdummy1
1

Stmt last use time : 02/27/2010 15:13:26.877157
Statement text : SELECT CREATE_TIME FROM
SYSTOOLS.HMON_ATM_INFO WHERE SCHEMA = ? AND NAME = ? FOR UPDATE
The "Stmt first use time" and "Stmt last use time" show
future-dated timestamps when compared to the current timestamp
on the server. This is a result of the underlying implementation
used to generate the timestamp data. Note that the problem has
only been seen with the deadlock event monitor, but may not be
limited to it. |

| Local-Fix: |
If the time drift grows to be intolerably substantial over time,
terminate all connections to the database, whose deadlock
monitor exhibits this problem, and reconnect. |
