Differences in 2 environment.xml

Post questions specific to installation or configuration for the HPCC Systems platform

Can you tell me what these differences mean?

The following shows differences in two environment.xml (lines beginning with "<" come from the 1st environment.xml and lines beginning with ">" come from the 2nd environment.xml. The differences are shown in pairs -- one from each environment.xml file.

For example, the 1st pair of differences show values for umask in DtopZone. So, I'm wondering what the 2 different values for umask mean.

Code: Select all
--------------------------------------------
< Environment.Software.DropZone:umask="002"
---
> Environment.Software.DropZone:umask="022"
--------------------------------------------

--------------------------------------------
< Environment.Software.RoxieCluster:channelsPerNode="2"
---
> Environment.Software.RoxieCluster:channelsPerNode="1"
--------------------------------------------

--------------------------------------------
< Environment.Software.RoxieCluster:copyResources="true"
---
> Environment.Software.RoxieCluster:copyResources="false"
--------------------------------------------

--------------------------------------------
< Environment.Software.RoxieCluster:lazyOpen="false"
---
> Environment.Software.RoxieCluster:lazyOpen="true"
--------------------------------------------

This is another question about an environment.xml file. In one environment.xml file I saw the following assignment.
Code: Select all
Environment.Software.SashaServerProcess.Instance:port="8877"

So, what does the sasha instance use port 8877 for?

The Roxie setting (Environment.Software.RoxieCluster:copyResources) is explained here:

http://cdn.hpccsystems.com/releases/CE- ... df#page=10

It is basically a setting telling it how to handle data when a query is published. It can read data from the original location or copy it to the Roxie itself (or a combination of both)

In a single node implementation, using remote makes the most sense. In a production setting, copying to the Roxie is usually best.

The Sasha port is used to communicate with other components. Each component uses a port or a range of ports.

HTH,
