Distributed System Properties for JMX Agent

Specify values for these admin distributed system-specific properties as a list of prop=value pairs on the agent command line or in the JMX Agent’s properties file. The SSL properties listed here affect communication between members of the distributed system.

Argument Comments Default Value

mcast-address

Multicast address of this distributed system. To use IP multicast, you must also define mcast-port, the IP port.

239.192.81.1

mcast-port

Multicast port, a value in the range 0..65535. To use IP multicast, you must also define mcast-address, the IP address.

10334

membership-port-range

Range of ports available for unicast UDP messaging and for TCP failure detection. This range is specified as two integers separated by a minus sign. Different members can use different ranges. SQLFire randomly chooses two unique integers from this range for the member, one for UDP unicast messaging and the other for TCP failure detection messaging. Additionally, the system uniquely identifies the member using the combined host IP address and UDP port number. You may want to restrict the range of ports that SQLFire uses so the product can run in an environment where routers allow traffic only on certain ports.

1024-65535

locators

Comma-delimited list whose elements have the form host[port]. When you use the SQLFire locator service, each locator is uniquely identified by the host on which it is running and the port on which it is listening.

""

remote-command

Default remote command prefix to use for command invocation on remote machines.

rsh -n {HOST} {CMD}

ssl-enabled

Indicates whether to use the Secure Sockets Layer (SSL) protocol for communication between members of this distributed system. Valid values are true and false. A true setting requires the use of locators.

false

ssl-protocols

Space-separated list of valid SSL protocols for this connection. Specify any protocol that is enabled by default in the configured Java Secure Sockets Extension (JSSE) provider.

any

ssl-ciphers

Space-separated list of valid SSL ciphers for this connection. Specify any ciphers that are enabled by default in the configured JSSE provider.

any

ssl-require-authentication

Indicates whether to require authentication for communication between members of the admin distributed system. Valid values are true and false.

true

tcp-port

TCP port to listen on for distributed system communications. If set to zero, the operating system selects an available port. Each process on a machine must have its own TCP port. Some operating systems restrict the range of ports usable by non-privileged users, and using restricted port numbers can cause runtime errors in SQLFire startup. Valid values are in the range 0..65535.
