Error description

• APAR Type:            Field
  Approver Initials:    AS
  Severity:             2
  Reported Release:     621
  Compid:               5608A41CI Distributed Installer
  ABSTRACT:             cinfo takes a long time in a non-DNS
  environment
  PROBLEM DESCRIPTION:
  
  cinfo (any option) has been found to run very slowly in an
  environment
  where DNS is not used for network name resolution. The response
  delay
  varies by OS platform.
  
  
  RECREATE INSTRUCTIONS:
  
  1) Configure a system to not use DNS for network name
  resolution.  The
     following instructions will work, there are sure to be
  additional
     variants that also work.
     A) For all OS's
        /etc/hosts contains all the required IP addresses and host
  names
     B) For all OS's
        /etc/resolv.conf contains no entries for DNS servers.
        (entries can be commented out instead of deleted)
     C) For AIX:
        /etc/netsvc.conf contains a hosts entry which has "local"
  on it
        and "bind" is not present.
     D) For Linux, HP-UX, and Solaris:
        /etc/nsswitch.conf contains a hosts entry which has
  "files" on it
        and "dns" is not present.
  
  2) Install OS agent from ITM 6.2.1 GA level
  3) Change directory to $CANDLEHOME
  4) Run "time bin/cinfo -i"
  5) Upgrade the OS agent to ITM 6.2.1 FP2
  6) Run "time bin/cinfo -i"
  7) Notice the time different required for the command to
  complete.

Local fix

• See http://www-01.ibm.com/support/docview.wss?uid=swg21433943
  

Problem summary

• The IBM Tivoli Monitoring command cinfo, with any options, has
  been found to run very slowly on a UNIX/Linux system
  in an environment where DNS is not used for network name
  resolution. The response delay varies by OS platform.
  

Problem conclusion

• ITMhostName, called by cinfo, has been updated to use only the
  command for each platform that supports a non-DNS configuration.
  For Linux and Solaris, "getent hosts" is used.
  For HP-UX, "nslookup" is used.
  For AIX, "host", without the -n parameter, is used.
