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. MDVREGR caused by APAR IZ63471 in 6.2.1-TIV-ITM-FP0002
Local fix
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. The fix for this APAR is included in the following maintenance vehicle: | fix pack | 6.2.1-TIV-ITM-FP0003 | fix pack | 6.2.2-TIV-ITM-FP0003
