一 某系统数据库后台报ORA-600错误

Fri Dec 05 22:00:09 2014

Errors in file /oracle/app/diag/rdbms/test/test2/trace/test2_j002_344438.trc  (incident=322196):

ORA-00600: internal error code, arguments: [unable to load XDB library], [], [], [], [], [], [], [], [], [], [], []

Incident details in: /oracle/app/diag/rdbms/test/test2/incident/incdir_322196/test2_j002_344438_i322196.trc:


二   查询步骤:

1 查询数据库实例的进程号

  $ ps -ef|grep smon

oracle 667750 1 0 Feb 18 - 0:13 asm_smon_+ASM

oracle 1007852 1 0 Feb 18 - 0:46 ora_smon_instance1

2 查询监听是否有继承性

$ ps -ef|grep lsn

---以下为查询结果

oracle 630852 1 0 Feb 18 - 10:06 /db01/app/oracle/product/11.2.0/grid2/bin/tnslsnr LISTENER -inherit

3 查询对应的数据库实例的环境变量是否设置:

$ ps eauwww 1007852   

---以下为查询结果

USER PID %CPU %MEM SZ RSS TTY STAT STIME TIME COMMAND

oracle 1007852 0.0 1.0 199752 90152 - A Feb 18 0:46 ora_smon_instance1 _=/db01/app/oracle/product/11.2.0/grid2/bin/oraagent.bin

LANG=en_US LOGIN=oracle __CLSAGENT_INCARNATION=2

[...]

ORA_CRS_HOME=/db01/app/oracle/product/11.2.0/grid2 

ORACLE_HOME=/db01/app/oracle/product/11.2.0/db2

LIBPATH=                    ---此处证明此环境变量未设置

LD_LIBRARY_PATH=

   经过查询,发现LIBPATH、LD_LIBRARY_PATH环境变量未设置。以下为官方解决方法。

The main cause for the error ORA-00600 [Unable to load XDB library] is when LIBPATH is not set, or incorrectly set, however
LIBPATH environment variable was set correctly before the database and the listener were started up.

CAUSE

The database was started with the

srvctl start database

command and the  result of 'ps eauwww <smon_pid> OS command, as in the follow example:

$ ps -ef|grep smon
oracle 667750 1 0 Feb 18 - 0:13 asm_smon_+ASM

$ ps -ef|grep lsn

shows that the LIBPATH was  not inherited by the smon process:
LIBPATH=

while it was inherited for the listener:
LIBPATH=/db01/app/oracle/product/11.2.0/grid2/lib:/opt/ORCLcluster/lib:/usr/lib.

Running

srvctl getenv database -d <dbname>


shows that there is no environment variable set at grid control level

SOLUTION

If the database starts via srvctl command, variables need to be set using the 'svrctl setenv' as in the following commands

srvctl setenv database -d <dbname> -t 'LIBPATH=<replace with full ORACLE_HOME Path>/lib'

srvctl setenv listener -t 'LIBPATH=<replace with full ORACLE_HOME Path>/lib'


Example:
srvctl setenv database -d v1122a32 -t 'LIBPATH=/u01/oracle/product/11.2.0.2/db_home1/lib'

and both the listener and the database must be restarted using again the srvctl command.
