Know Current Oracle Database Version Usage

前2周有客户向我咨询现在市面上的Oracle数据库各版本的使用率,考虑到10g将会在2013年超出Extentd Support期,客户希望找到合适的时机升级到11gr2上。

在网上找了一圈,包括IDC似乎都没有公开的调查结果。反而在OTN Database Forum上找到一个”Poll Results: Your production database version”老外搞的生产库版本投票。

这个投票结果在一定程度上反映了国际上Oracle数据库各版本的使用率:10gr2目前使用率最高,11gr2在迅速追上。但因为国外的IT建设要领先于国内,所以我们可以推测国内的实际情况是9ir2和10gr2占主导地位,11gr2仍打酱油。

可以看到以上引发ORA-00600[kgskdecrstat1]内部错误的进程同时发现了死锁(DEADLOCK),在MOS上搜索可以发现”Bug 2894072: ORA-00600: INTERNAL ERROR CODE, ARGUMENTS: [KGSKDECRSTAT1]”,但是该Bug最早发生在9.2.0.3上,已经确定影响9.2.0.x所有版本,并且在9.2.0.5上没有backport的bug fix。

提交sr后,Oracle Gcs给出了解决的solution:
1.升级数据库到10.2.0.5,11.1.0.7,11.2.0.2等目前支持的版本
2.解决引发该bug的ORA-00060 dead lock问题
3.如果在解决ORA-00060后仍出现以上ORA-00600[kgskdecrstat1]内部错误,且启用了9i早期版本中的resource manager的话,可以尝试禁用该特性:
ALTER SYSTEM SET resource_manager_plan=” SCOPE=BOTH;
以便绕过bug 2494790。

Oracle内部错误:ORA-00600[OSDEP_INTERNAL]一例

Getting ORA-600 [OSDEP_INTERNAL] errors while starting up the database:

ORA-27301: OS failure message: No space left on device
ORA-27302: failure occurred at: sskgpsemsper
Symptoms
Getting ORA-600 [OSDEP_INTERNAL]
Accompanied by the following errors
ORA-27302:Failure occured at: skgpwreset1
ORA-27303:additional information: invalid shared ctx
ORA-27146: post/wait initialization failed
ORA-27300: OS system dependent operation: segment failed with error 28
ORA-27301: OS system Failure message: No space left on device
ORA-27302: failure occured at: sskgpsemsper
Cause
The functions in the trace file generated point to the semaphore settings .
Smmns is set too low.
Solution
set semmns 32767
Arrange to make the changes persistent as per the Operating system then restart the server and check if the changes are persistent.
eg: Linux /etc/sysctl.conf
sem = semmsl semmns semopm semmni
kernel.sem = 256 32768 100 228
Getting ORA-00600 [OSDEP_INTERNAL]: Internal Error While Trying To Connect / As Sysdba [ID 253885.1]
Applies to:
Oracle Server - Enterprise Edition - Version: 9.2.0.3 and later   [Release: 9.2 and later ]
HP-UX PA-RISC (64-bit)
Symptoms
Getting following error while trying to connect as sysdba using sqlplus:
SQL> conn / as sysdba
ERROR:
ORA-01041: internal error. hostdef extension doesn't exist
Alert.log shows:
ORA-00600: internal error code, arguments: [OSDEP_INTERNAL], [], [], [], [], [],[], []
ORA-27302: failure occurred at: skgpwinit4
ORA-27303: additional information: attach to invalid skgp shared ctx
Cause
- Database was shutdown using "shutdown abort" option.
- Shared memory segment was not removed even though the instance was down.
Solution
+ Check which shared memory segments are owned by the oracle owner
Use the ipcs -bm command:
% ipcs -bm
m 34034336 0xf8f18468 --rw-r----- ORACLE dba 16777216
+ Delete the 'orphan' shared memory segments:
% ipcrm -m 34034336
If there is more than one instance running on the server and you are not sure how to identify the shared
memory segments then please contact support.

不恰当的设置OS VM参数可能导致该问题,而在HP-UX PA-RISC平台上使用'shotdown abort'命令时可能因为共享内存未能正常移除而出现该内部错误;因为实例还是以'abort'方式关闭的,仅仅是共享内存未能释放,所以只需要以ipcs->ipcrm等os命令将相应的共享内存段释放就可以了,不会造成其他影响。
