Oracle 11.2.0.2 bug还是不少的。很多库迁到Oracle 11.2.0.2后都遇到了问题。现在正在跟的两个Oracle 11.2.0.2上的问题:1.ORA-0

Oracle 11.2.0.2 bug还是不少的。
很多库迁到Oracle 11.2.0.2后都遇到了问题。
现在正在跟的两个Oracle 11.2.0.2上的问题:
1.ORA-00600: internal error code, arguments: [ktecgsc:kcbz_objdchk], [0], [0], [1],

2.这个更扯,遇到几次了。想要enable block change tracking就会hang住。
SQL> select SID from  v$mystat where rownum       SID
----------
       321
SQL> alter database enable block change tracking using file'/prod/dba/oracle/jporp/admin/ctf/block_change.ctf' reuse;
----Hang在这里


此时另外开一个session去看:
SQL> select SID,program,event,blocking_INSTANCE,BLOCKING_SESSION from v$session where sid=321 or  BLOCKING_SESSION=321 or sid=610;      
       SID PROGRAM              EVENT                BLOCKING_INSTANCE BLOCKING_SESSION
---------- -------------------- -------------------- ----------------- ----------------
       321 sqlplus@xxxx         DFS lock handle                      1              610
       350 oracle@xxxx(CTWR).   enq: CT - state chan ge gate 2       1              321
       610 oracle@xxxx(CKPT).   rdbms ipc reply                      1              350

这个执行enable BCT的session 321,激活了CTWR进程350,结果321,350,再通过610 CKPT进程生了cycle。就hang 在那了。
