24.3.2.3. jgroups-ec2.xml
jgroups-ec2.xml is a pre-configured JGroups file in Red Hat JBoss Data Grid. The jgroups-ec2.xml configuration
- uses TCP as a transport and S3_PING for discovery.
- is suitable on Amazon EC2 nodes where UDP multicast isn't available.
As with other pre-configured JGroups files, the behavior of some of these settings can be altered by adding certain system properties to the JVM at startup. The settings that can be configured are shown in the following table.
| System Property | Description | Default | Required? |
|---|---|---|---|
| jgroups.tcp.address | IP address to use for the TCP transport. | 127.0.0.1 | No |
| jgroups.tcp.port | Port to use for TCP socket | 7800 | No |
| jgroups.s3.access_key | The Amazon S3 access key used to access an S3 bucket | Yes | |
| jgroups.s3.secret_access_key | The Amazon S3 secret key used to access an S3 bucket | Yes | |
| jgroups.s3.bucket | Name of the Amazon S3 bucket to use. Must be unique and must already exist | Yes | |
| jgroups.s3.pre_signed_delete_url | The pre-signed URL to be used for the DELETE operation. | Yes | |
| jgroups.s3.pre_signed_put_url | The pre-signed URL to be used for the PUT operation. | Yes | |
| jgroups.s3.prefix | If set, S3_PING searches for a bucket with a name that starts with the prefix value. | No |
