ORA-00600: internal error code, arguments: [keltnfy-ldmInit], [46], [1], [], [], []

 今天建库的时候忽然报错ORA-00600: internal error code, arguments: [keltnfy-ldmInit], [46], [1], [], [], [], [], [] 梗是让我无语，没办法只好检查参数配置，按照文档一步步检查，最后检查了下profile文件的配置 
[root@servU_01 db_1]# more /home/oracle/.bash_profile 
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH

export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

export NLS_LANG="SIMPLIFIED CHINESE_CHINA".ZHS16GBK

export ORACLE_SID=perm

stty erase ^H 

发现没有错误，再次运行DBCA -> 还是报错ORA-00600: internal error code, arguments: [keltnfy-ldmInit], [46], [1], [], [], [], [], []

最后参考metalink上信息，按照metalink上信息显示，可能是DNS或者hosts文件配置有问题，最后检查果然是是hosts文件配置不正确，修改hosts文件配置后，问题得以解决

Symptoms
An startup nomount on Oracle 10g Release 2 database produces the following exception in alert log
Starting up ORACLE RDBMS Version: 10.2.0.1.0.
Errors in file /opt/oracle/10.2/admin/ORCL/udump/ORCL_ora_535.trc:
ORA-00600: internal error code, arguments: [keltnfy-ldmInit], [46], [1], [], [], [], [], []
USER: terminating instance due to error 600
Instance terminated by USER, pid = 535
Cause
The problem is related to getting host information.
In this case, ldmInit()/sldmInit() is failing with error 46 : LDMERR_HOST_NOT_FOUND
The following exception may also occur :
LDMERR_SOSD_INIT         OSD init failed to be specific in these OSD failures
 LDMERR_BAD_ADDR         bad address when system call gethostname failed
 LDMERR_HOST_NOT_FOUND   gethostbyname system call fails
 LDMERR_NO_SUPPORT       when specific address type is not supported

Development has fixed two bugs so far regarding this issue

Bug:5438154 - Abstract: ORA-600[KELTNFY-LDMINIT]  STARTING THE DB 
Release Notes: 
ldmInit returned LDMERR_HOST_NOT_FOUND for the machine huge alias list/address list 
Workaround: 
reduce the alais list of the machine
Bug:5486074 - Abstract: ORA-600 [KELTNFY-LDMINIT] WHEN DNS IS NOT AVAILABLE
Release Notes: 
Internal error is raised by the Server Generated Alert subsystem when it can not determine Host Name or 
Network Address. This can be caused by DNS server being unaavilable.
Solution
The fix for 5486074 will not fix any underlying error from gethostbyname(), it just change the internal error to a warning message :
   
   
  
 "Warning: keltnfy call to ldmInit failed with error 46"
 

You will still need to fix the network config issue.  

These are the check you can do verify the host information 

 
 
·         Check permission on /etc/hosts
   
   
$ ls -l /etc/hosts 
-rw-r--r--  2 root root 194 Oct 17  2006 /etc/hosts
 
    
·         Check if /etc/hosts file is correctly configured
   
   
  
 <ip address>     <fully qualified hostname>   <simple or short hostname>  <alias, if applicable>   ( all of this on one line ).
 
 
 
·         Check the hostname:
   
   
$ hostname
  
$ ping `hostname`
 
Make sure you are able to ping the hostname


 
·         Check if /etc/nodename is correctly configured
·         If you have DNS setup, ping is not a tool to diagnose DNS problem. A better tool to use is nslookup, dnsquery, or dig.
   
   
  
$ nslookup <shortname>  
$ nslookup <long name>  
$ nslookup <ip address>
 
The forward and reverse lookup should succeed and return consistent address/info.  

 
 
·         Check nsswitch.conf
   
   
$ more nsswitch.conf
hosts:      files dns
Make sure host lookup is also done through the /etc/hosts file and not just dns.  It is recommended that FILES come first before DNS.
 
 
·         Also, check the resolv.conf. This makes sure that the DNS is working properly.
