Installing and Configuring SAS Environment Manager in a Grid Environment

If you are installing SAS Environment Manager in a grid environment where more than one grid machines share a configuration directory, you must perform manual configuration steps so that the SAS Environment Manager agents point to the correct machine. A script is available on support.sas.com to automate this process. The manual steps are provided below.

The following procedure is for two grid machines running on UNIX. Follow these steps:

Stop the SAS Environment Manager agent running on the SAS Grid Control server.
```
$SAS_config/Web/SASEnvironmentManager/agent-5.8.0-EE/bin/hq-agent.sh stop
```
Create a target directory for the SAS Environment Manager agent on a grid node.
```
mkdir -p $SAS_config/Web/SASEnvironmentManager/grid/$grid_node
```
grid_node is the name of a grid node machine.
Copy the agent directory structure from the SAS Grid Control server into the target directory on the grid node
```
cp -pr $SAS_config/Web/SASEnvironmentManager/agent-5.8.0-EE 
$SAS_config/Web/SASEnvironmentManager/grid/$grid_node
```
Remove the agent data/ directory on the grid node machine.
```
rm -rf $SAS_config/Web/SASEnvironmentManager/grid/$grid_node/agent-5.8.0-EE/data
```

Create a backup of the agent property file on the grid node machine.

mv $SAS_config/Web/SASEnvironmentManager/grid/$grid_node/agent-5.8.0-EE/conf/agent.properties 
$SAS_config/Web/SASEnvironmentManager/grid/$grid _node/agent-5.8.0-EE/conf/agent.properties.orig

Update the agent property file on the grid node machine.

 sed "s/^agent.setup.agentIP=.*/agent.setup.agentIP=$grid_host/" 
$SAS_config/Web/SASEnvironmentManager/grid/$grid_node/agent-5.8.0-EE/conf/agent.properties.orig > 
$SAS_config/Web/SASEnvironmentManager/grid/$grid_node/agent-5.8.0-EE/conf/agent.properties

Create a backup of the SAS custom agent property on the grid node machine.

mv $SAS_config/Web/SASEnvironmentManager/grid/$grid_node/agent-5.8.0-EE/conf/sas.properties 
$SAS_config/Web/SASEnvironmentManager/grid/$grid_node/agent-5.8.0-EE/conf/sas.properties.orig

Link the SAS custom agent property file to the original custom agent property file on the grid node machine.

ln -s $SAS_config/Web/SASEnvironmentManager/agent-5.8.0-EE/conf/sas.properties 
$SAS_config/Web/SASEnvironmentManager/grid/$grid_node/agent-5.8.0-EE/conf/sas.properties

Repeat steps 2 through 8 for all grid mode machines.
Start the SAS Environment Manager agent on the SAS Grid Control server.
```
$SAS_config/Web/SASEnvironmentManager/agent-5.8.0-EE/bin/hq-agent.sh start
```
