RDMA_CONNECTION_INFO view

The RDMA_CONNECTION_INFO view returns one row for each Remote Direct Memory Access (RDMA) connection.

Authorization: The privileges held by the authorization ID of the statement must include the following:

*EXECUTE authority on the QSYS2 library.
*OBJOPR and *READ authority on QSYS2/RDMA_CON.
For the authority needed to use this view, see Authorization.

The following table describes the columns in the view. The system name is RDMA_CON. The schema is QSYS2.

Table 1. RDMA_CONNECTION_INFO view
Column Name	System Column Name	Data Type	Description
ADDRESS_SPACE_TYPE	ADDR_TYPE	CHAR(4)	The IP address space type for `SOURCE_ADDRESS` and `TARGET_ADDRESS`. IPV4 The address is specified using the IPv4 address space type. IPV6 The address is specified using the IPv6 address space type.
SOURCE_ADDRESS	SRC_ADDR	VARCHAR(45)	Local IP address for this link. When `ADDRESS_SPACE_TYPE` is `IPV4`, the address is in IPv4 format. When `ADDRESS_SPACE_TYPE` is `IPV6`, the address is in IPv6 format.
SOURCE_PORT	SRC_PORT	INTEGER	Port number for this connection on the local node.
TARGET_ADDRESS	TGT_ADDR	VARCHAR(45)	Remote IP address for this link. When `ADDRESS_SPACE_TYPE` is `IPV4`, the address is in IPv4 format. When `ADDRESS_SPACE_TYPE` is `IPV6`, the address is in IPv6 format.
TARGET_PORT	TGT_PORT	INTEGER	Port number for this connection on the remote node.
CONNECTION_STATE	STATE	VARCHAR(11)	State of the connection. CONNECTING An attempt to establish a connection to the remote host is being made. ERROR The connection is in error. ESTABLISHED The normal state in which data is transferred. LISTEN Waiting for a connection request from a remote host.
CONNECTION_ERROR	ERROR	INTEGER	The error code associated with the socket if `CONNECTION_STATE` is `ERROR`.
NRG_NAME	NRG_NAME	VARCHAR(15)	The Network Redundancy Group (NRG) name.
JOB_NAME_COUNT	JOB_COUNT	SMALLINT	The number of job name entries in the `JOB_NAME` column.
JOB_NAME	JOB_NAME	VARCHAR(2899)	A list of up to 100 qualified job names for the connection endpoint. The list is an array of 29 character entries which guarantees at least one blank between entries.
IDLE_TIME	IDLE_TIME	DECIMAL(19,3)	Idle time, in seconds, since the last activity on this connection.
SEND_BUFFER_SIZE	SEND_SIZE	INTEGER	Size of send buffer, in bytes.
RECEIVE_BUFFER_SIZE	RCV_SIZE	INTEGER	Size of receive buffer, in bytes.
REQUESTS_IN	REQ_IN	INTEGER	The number of incoming requests.
REQUESTS_OUT	REQ_OUT	INTEGER	The number of outgoing requests.
BYTES_IN	BYTES_IN	BIGINT	The number of incoming bytes.
BYTES_OUT	BYTES_OUT	BIGINT	The number of outgoing bytes.
OUTSTANDING_SEND_REQUESTS	SND_REQ	INTEGER	The number of outstanding send requests issued that have not yet completed.
OUTSTANDING_USER_SEND_ REQUESTS	USRSND_REQ	INTEGER	The number of outstanding user RDMA send requests issued that have not yet completed.
OUTSTANDING_USER_RECEIVE_ REQUESTS	USRRCV_REQ	INTEGER	The number of outstanding user RDMA receive requests issued that have not yet completed.
BUFFER_WAITS	BUF_WAITS	INTEGER	The number of times that send operations have had to wait for available space in the remote receive buffer in order to send data.
WAIT_TIME_ON_REMOTE_RECEIVE_ BUFFER	WAIT_TIME	DECIMAL(19,3)	The total time, in seconds, that send operations have had to wait for available space in the remote receive buffer in order to send data.
