oracle 10.2.0.3 rac数据库下用sql监控性能的一个bug说明

数据库环境 oracle 10.2.0.3 rac + aix 5300-06
昨天在客户那数据库巡检时，发现以下错误:
Errors in file /opt/oracle/admin/oa/bdump/oa1_s000_430442.trc
ORA-00600: internal error code, arguments: [kolaslGetLength-1], [], [], [], [], [], [], []
通过 more opt/oracle/admin/oa/bdump/oa1_s000_430442.trc
看到是由于以下sql导致
Select s.inst_id, s.username, s.sid, s.serial#, command, t.value cpu_time, i.physical_reads phy_reads, i.block_gets blk_gets, s.st
atus, s.lockwait, q.sql_fulltext sql_text, s.sql_hash_value
FROM GV$session s, GV$sesstat t, GV$statname n, GV$sess_io i, GV$sqlarea q
WHERE s.username is not null
AND (t.value > :"SYS_B_0" or i.physical_reads > :"SYS_B_1" or i.block_gets > :"SYS_B_2")
AND s.sid = t.sid AND s.inst_id = t.inst_id AND t.statistic# = n.statistic# AND t.inst_id = n.inst_id AND n.name = :"SYS_B_3" AND
s.sid = i.sid AND s.inst_id = i.inst_id AND s.sql_address = q.address AND s.sql_hash_value = q.hash_value AND s.inst_id = q.inst_i
d ORDER BY t.value desc
通过查询metalink 已经确认是oracle 10.2.0.3下的bug,这个是toad工具连接到数据库监控性能时导致的
要解决这个问题，必须升级到oracle 10.2.0.4 或11g
以下是metalink详细解释
