GigaSpaces Configuration (Magic xpi 4.1)

The GigaSpaces infrastructure is composed of multiple server processes running on multiple machine instances (physical or virtual) that work together to store large amounts of data in memory, thereby achieving high performance, elastic scalability, and fail-safe redundancy. This screen lets you configure the GigaSpaces infrastructure’s details.

• In the Service Configuration section of the screen, select the Install the Grid Service Agent (GSA) as a service check box. This installs the GSA service on your machine automatically during the Magic xpi installation process. The name of the GSA service will appear in the Service Name field.

• In the Space Configuration section of the screen, configure the following properties:

• • Select the Development Machine check box if you want to configure the Space to run only on your development machine. With this option, the Use the following locators (Unicast) field will contain the 127.0.0.1 loopback address in read-only form, the Number of GSCs field will be set to 1 by default, and the GSC Memory Allocation (In GB) field will be set to 128 by default. The Run the LUS check box will be selected by default.

  • Clear the Development Machine check box if you want to deploy the Space in a clustered environment. With this option, enter the addresses (comma separated) of the application servers that you designated as LUS servers in the Use the following locators (Unicast) field.

In the Number of GSCs field, enter the number of Grid Service Containers that you want to deploy.

In the GSC Memory Allocation (In GB) field, enter the amount of memory that you want to allot to the GSCs.

Select the Run the LUS check box to run the LUS locally on this machine.

• In the Space Deployment section’s Number of Partitions field, enter the number of partitions that you want your Space to contain. Finally, select the Partition Backup check box to have a backup for each of the partitions.

If you selected the Development Machine check box (above), the Number of Partitions field will be selected by default, and the Partition Backup check box will be cleared by default.
