Testing the System Environment
To perform simple system testing, you should use the
space-instance.bat script in Windows environments or
space-instance.sh script in Linux environments.
For information on how to set up a production environment, refer to the Moving into Production Checklist.
- Run a single Space instance by moving to the
$GS_HOME\bindirectory and running the
space-instance.bat/shcommand. You should see output like the following:

- Make sure it loads without errors or exceptions. If you have errors or exceptions, check the following:
JAVA_HOMEenvironment variable - Make sure it points to a valid JDK folder.
- Network setup - Make sure the machine has a valid network interface installed with a valid IP.
- hosts file - Make sure it includes entry for
localhostor other machines you are accessing.
- Multiple NICs - If your machine running multiple network interfaces, make sure you have the
GS_NIC_ADDRESSenvironment variable set to a valid IP of the machine. This should be done on every machine running GigaSpaces.
- User permissions - Make sure you run the
gsInstnce.shscript with a linux user that has permissions to write into the
CLASSPATHenvironment variable - Make sure the
CLASSPATHenvironment variable is not specified. You might have some libraries specified as part of the
CLASSPATHthat cause GigaSpaces to fail.
GS_HOME- environment variable - Make sure the
GS_HOMEenvironment variable is not specified or pointing to a different GigaSpaces release folder. You may have another GigaSpaces release installed on the same machine with the
GS_HOMEvariable pointing to this release folder.
- Ping the Space by running the
gs space ping -url jini://*/*/mySpace
The following using multicast lookup discovery protocol. The first
* of the URL means search for the lookup service across the network using multicast.
The following result output should appear on the console:
D:\gigaspaces-xap-premium-8.0.1-ga\bin>gs space ping -url jini://*/*/mySpace total 1 ping from <mySpace> space with: Finder URL: jini://*/*/mySpace?timeout=5000 Lease Timeout: 10 seconds LookupFinder timeout: 5000 milliseconds Buffer Size: 100 Iterations: 5 Average Time = 135 milliseconds
Subsequent Space ping calls will have much faster response time. The fist space ping call introduce some metadata to the Space. This happens only once.
If the Space ping call fails with the following:
total 0 Service is not found using the URL: jini://*/*/mySpace?timeout=5000
You have the following options:
- Make sure your network and machines running GigaSpaces products are configured to have multicast enabled. See the How to Configure Multicast section for details on how to enable multicast.
- Perform a Space ping using unicast lookup discovery protocol:
gs space ping -url jini://localhost/*/mySpace.
The following result should appear on the console:
D:\gigaspaces-xap-premium-8.0.1-ga\bin>gs space ping -url jini://localhost/*/mySpace total 1 ping from <mySpace> space with: Finder URL: jini://localhost/*/mySpace?timeout=5000 Lease Timeout: 10 seconds LookupFinder timeout: 5000 milliseconds Buffer Size: 100 Iterations: 5 Average Time = 135 milliseconds
When the ping client running on a remote machine (other than the machine running the Space),
localhost should be replaced with the machine hostname or IP running the Space instance.
Repeat the above steps #3, where the ping command is called from a machine different than the one running the Space. You will have to install GigaSpaces both on the client and server machines.
