-Dcom.ibm.net.rdma.socketOptions=filename
List the socket options as key-value pairs in a plain text file, then supply the filename as the parameter for the -Dcom.ibm.net.rdma.socketOptions property. The file path must be either absolute or relative to the location of the VM. The following socket options are supported:
  • SendBufferSize=integer_value_in_bytes
  • ReceiveBufferSize=integer_value_in_bytes
  • SendQueueSize=integer_value
  • ReceiveQueueSize=integer_value
  • SendInlineSize=integer_value
Other properties are ignored.
You can also specify these options by using the following environment variables:
  • IBM_JAVA_RDMA_SBUF_SIZE
  • IBM_JAVA_RDMA_RBUF_SIZE
  • IBM_JAVA_RDMA_SQ_SIZE
  • IBM_JAVA_RDMA_RQ_SIZE
  • IBM_JAVA_RDMA_INLINE
These environment variables take precedence over socket options that you specify by using the -Dcom.ibm.net.rdma.socketOptions property.
