Install

Download the source package
Unzip into the /opt directory
Setup GAT_LOCATION environment variable

To install only the GAT engine or the adaptors, build them separately.

before starting the build, please ensure that the environment variable $GAT LOCATION points to the parent directory of GAT.
to build the engine, change to the directory $GAT LOCATION/engine, and enter ant

to build the adaptors, change to the $GAT LOCATION/adaptors, and enter ant.

administrator's script: install.sh

# Set BASE_URL link
```

BASE_URL="http://mirror.scc.kit.edu/downloads/src/gat/2010.1"

```
PACKAGE_VERSION="gat-astro" 
```
```
PACKAGE_NAME=${PACKAGE_VERSION}".tgz"

```
# Setup GAT_LOCATION
```
```
if [ ! -f ${GAT_ENV} ];
```
```
then
```

    echo "export GAT_LOCATION=${DIR_WORK}" > ${GAT_ENV}

```
fi
```

# The file should be marked as executable:

```
chmod +x ${GAT_ENV}
```

#In order to execute this script for every user automatically, link in the directory /etc/profile.d as follows:

```
ln -s ${GAT_ENV} /etc/profile.d
```

Configure

Run ant command into the $GAT_LOCATION directory
to build the Command Line Interfaces (CLI) GATJobRun and GATFileOps, additional steps are required:
- download the GATJobRun and GATFileOps packages
- run ant -f build-standalone.xml into the appropriate directory

administrator's script: configure.sh

```
 
```
```
#!/bin/sh
```
```
# configure JavaGAT 
```
```
export GAT_LOCATION=$DIR_WORK
```
```
cd $DIR_WORK
```
```
# call ant
```
```
ant
```
```
 
```
```
# configure GATJobRun
```

cd $DIR_WORK/astrogrid-packages/GATJobRun/

```
ant -f build-2.0.xml
```
```
 
```
```
# configure GATFileOps
```

cd $DIR_WORK/astrogrid-packages/GATFileOps/

```
ant -f build-standalone.xml
```

Proceed

the entry point to GATJobRun is the script gat-job-run which is located in the directory $GAT_LOCATION/astrogrid-packages/GATJobRun/scripts.
the entry point to GATFileOps is the script gat-file-operation which is located in the directory $GAT_LOCATION/astrogrid-packages/GATFileOps/scripts.

It is recommended to add this directory to the PATH environment variable, to enable an easy usage from everywhere directory in your system.

administrator's script: proceed.sh

```
 
```
```
#!/bin/sh
```

# operating with GATJobRun and GATFileOps

# add GATJobRun/scripts GATFileOps/scripts into the PATH environment variable

PATH=$PATH:$GAT_LOCATION/astrogrid-packages/GATJobRun/scripts

```
# run gat-job-run
```
```
gat-job-run
```
```
 
```

PATH=$PATH:$GAT_LOCATION/astrogrid-packages/GATFileOps/scripts

```
# run gat-file-operation
```
```
gat-file-operation
```
