Additional Steps for Informix
Logon as root to the primary host of the database where the package is
running in debug mode.
IR970 Informix Database Step:
Perform the following steps as an INFORMIX user:
su - informix
Comment out the remsh sections in the files called .dbenv.csh and
.dbenv.sh in the home directory. If they are missing, check for
alternative files with hostnames in them:
.dbenv_<local>.csh and .dbenv_<local>.sh.
The remsh section looks similar to:
# remsh <local> date >& /dev/null
# if ( $status <= 0 ) then
# echo Remote login check to dbserver <local> failed.
# echo Check if <local> is alive and file ...
# echo on <local> contains an entry for ...
# endif
Copy the two .dbenv files over to the INFORMIX home directory on all
cluster nodes, all external application server hosts, and Serviceguard by
using ftp.
NOTE If you do not do this, switching time increases dramatically; each remsh
command to the original database host causes delay if the node is not
available.
