4.3 Configuring the MDR Shell
As part of the configuration, the MDR host software needs to read some parameters
from a configuration file called mdr.ini. This file is stored in the mdr-host-sw/etc
directory. In order for the MDR host software to know where to find this file, the
environment variable
MDR_BASE needs to point to the base of the MDR software
installation. Therefore, the user has to declare an environment variable called
MDR_BASE.
This variable specifies the base directory of the ‘MDR tree’. The mdr.ini file is
expected to be in the sub-directory called etc/ of the directory specified by MDR_BASE.
In the UNIX csh environment, MDR_BASE may be set with the command:
#setenv MDR_BASE /<mdr directory path>/mdr
In the Windows environment, MDR_BASE may be set with the command:
C:\>set MDR_BASE=/<mdr directory path>/mdr
In the Power PC (VxWorks) environment, MDR_BASE may be set with the command:
->putenv (“MDR_BASE=/<mdr directory path>/mdr”)
In the UNIX environment, the path to the file
libmdrapi.so.0 (present in mdr-host-
sw/lib/sun-solaris/.libs
) must be added to the LD_LIBRARY_PATH environment
variable.
In the Windows environment, the path to the files
mdrapi.dll and cygwin32.dll (pre-
sent in mdr-host-sw/lib/x86-win32) must be added to the PATH environment vari-
able.
The MDR is shipped without any server lines defined in the mdr.ini file because the
layout of the network is unknown. The user may optionally define servers to which the
MDR Shell will attempt to connect automatically. The same is true for the mdr.ini file
installed on the MDR unit itself. Without any server lines, the resident MDR shell will
prompt for the "MDR Server hostname or IP address:" (i.e. the name or IP address of the
MDR unit).
To define a server line for the MDR resident shell, reset the MDR, enter the MIDAS
Monitor and type the command:
#iset Servers sX <IP addr> mdr.ini
where X is a number starting at 1 and <IP Addr> is the IP address for the MDR unit.
The mdr.ini file looks something like this:
# MDR configuration file
[Servers]
## s1,s2,...sn specifies which MDR servers to communicate with
s1=midas
