How Do I Check Whether Host Names in the SUSE Linux System Files Are the Same

How Do I Check Whether Host Names in the SUSE Linux System Files Are the Same

Question

If the server host name is modified incompletely before Oracle is installed, the host names in the SUSE Linux system files will be different.

How do I check whether the host names in the SUSE Linux system files are the same?

Answer

  1. Log in to the SUSE Linux server and run the following command to view the host name in the system file.

    # uname -a

    Information similar to the following is displayed:

    Linux eSightServer 3.0.101-0.47.99-default #1 SMP 2010-05-20 11:14:20 +0200 x86_64 x86_64 x86_64 GNU/Linux

    The host name is eSightServer.

  2. Run the following command to view the host name in the system file.

    # more /etc/hosts

    Information similar to the following is displayed:

    # 
    # hosts         This file describes a number of hostname-to-address 
    #               mappings for the TCP/IP subsystem.  It is mostly 
    #               used at boot time, when no name servers are running. 
    #               On small systems, this file can be used instead of a 
    #               "named" name server. 
    # Syntax: 
    #     
    # IP-Address  Full-Qualified-Hostname  Short-Hostname 
    # 
     
    127.0.0.1       localhost  
     
    # special IPv6 addresses 
    ::1             localhost ipv6-localhost ipv6-loopback 
     
    fe00::0         ipv6-localnet  
     
    ff00::0         ipv6-mcastprefix  
    ff02::1         ipv6-allnodes  
    ff02::2         ipv6-allrouters  
    ff02::3         ipv6-allhosts  
    10.137.59.36    eSightServer eSightServer     

    The host name is eSightServer.

  3. Check whether the two host names are the same. If they are different, contact SUSE Linux system administrator.
