To set up a parallel processing configuration, set system
environment variables on the conductor node and compute node. Also
verify that a temporary directory exists on the C: drive.
Before you begin
You must have Administrator privileges on the conductor node
and compute node computers.
About this task
Do this procedure on the conductor node and on each compute
node.
Procedure
- On the conductor node and on each compute node, use the Microsoft Windows Control Panel to set the following
environment variables. Ensure that you specify these environment variables
in all capital letters:
Table 1. Environment
variables to set on the conductor node and compute nodes
Environment variable |
Setting |
APT_PM_NOWAITPID |
1 |
APT_DISABLE_TRACKER_STARTUP |
1 |
APT_ORCHHOME |
The fully qualified path to the PXEngine directory.
Use forward slashes instead of backslashes in this specification.
For example:C:/IBM/InformationServer/Server/PXEngine
|
- On the compute nodes, update the system PATH environment
variable value. You do not need to update this value on the conductor
node.
- In the PATH value, add the paths to the parallel engine
binaries (executables and DLLs). Add the new paths directly before
or after the MKS Toolkit references. Use the standard Windows notation (backslashes) for these
specifications.
For example:
C:\IBM\InformationServer\Server\PXEngine\bin;C:\PROGRA~1\MKSTOO~1\bin;C:\
PROGRA~1\MKSTOO~1\bin\X11;C:\PROGRA~1\MKSTOO~1\mksnt; ...
- Verify that the MKS Toolkit paths in the PATH value
precede any
DSEngine
paths. If DSEngine
paths
precede MKS Toolkit paths, edit the variable value so that the DSEngine
paths
follow the MKS Toolkit paths. For example:
C:\IBM\InformationServer\Server\PXEngine\bin;C:\PROGRA~1\MKSTOO~1\bin;C:\
PROGRA~1\MKSTOO~1\bin\X11;C:\PROGRA~1\MKSTOO~1\mksnt;C:\IBM\InformationSe
rver\Server\DSEngine\bin ...
- On the conductor node and on each compute node, if you
installed InfoSphere® Information Server on
a drive other than C: (for example, D:), create a tmp directory
on the C: drive if the directory does not exist on the C: drive.
For example, C:\tmp.
