Session
4.12.1 Control: 0x0201 (attach to the named session)
Signature:
attach( options: map, name: session-name, opening: bit, next-command: sequence-no,
acknowledged: sequence-no, received: sequence-no, capacity: uint32, timeout:
uint32, txn-mode: txn-level, txn-support: txn-level )
Indicate that a session endpoint has been attached to a connection. A session MUST NOT be mapped to
more than one connection at a time.
Field Details:
options: map
options map (optional)
name: session-name
opening: bit
the session name (required)
The name of the session whose endpoint has been attached to the connection.
true iff the session endpoint has never been attached
(optional)
This field, if set, indicates that the session endpoint is newly created and has never been
attached to another endpoint.
next-command: sequence-no
(optional)
The id that will be assigned to the next outgoing command passed to the endpoint. For an
opening endpoint this will be the id of the next command sent from the endpoint.
acknowledged: sequence-no
(optional)
The id of the last acknowledged command. This marks the head of the replay buffer. If the
endpoint is newly created, this will be null.
received: sequence-no
the id of the last command received (optional)
The id of the last received command. This field MUST be set if and only if the session has
received commands. This field indicates where replay will begin when resuming a session.
capacity: uint32
timeout: uint32
(optional)
This value should be given relative to received if the opening bit is false.
the session timeout (optional)
The session timeout indicates how long the endpoint will be kept when detached. If not set, the
endpoint will be kept indefinitely.
txn-mode: txn-level
txn-support: txn-level
the desired txn-level (optional)
the maximum supported txn-level (optional)
