SID
|
NUMBER
|
Session identifier. |
SERIAL#
|
NUMBER
|
Session serial number. Used to identify uniquely a session's objects. Guarantees that session-level commands are applied to the correct session objects if the session ends and another session begins with the same session ID. |
NAME
|
VARCHAR2(71)
|
Replication Parallel Prop Slave n indicates that the slave process is active, either waiting, pushing deferred transactions, purging metadata, or creating an error transaction.
Replication Parallel Prop Coordinator indicates that the coordinator process is active, either waiting, sleeping, or scheduling slaves to perform operations.
The Replication Parallel Prop Coordinator reads transactions from the deferred transaction queue and assigns them to the Replication Parallel Prop Slaves . Then, the slaves propagate the transactions to the destination site. When the slaves push transactions in a push session, the slaves remain active until the push session completes, even if there are no more transactions to push. |
DBLINK
|
VARCHAR2(128)
|
Database link on which this replication session is propagating. |
STATE
|
VARCHAR2(12)
|
WAIT indicates that either the slave or coordinator process is waiting for an event (that is, a message).
SLEEP indicates that the coordinator process is sleeping for the duration of the delay_seconds setting. You set delay_seconds with the SCHEDULE_PUSH procedure in the DBMS_DEFER_SYS package.
PUSH indicates that the slave process is pushing transactions from the deferred transaction queue to the remote site.
PURGE indicates that the slave process is purging metadata related to successfully applied transactions from the remote site.
CREATE ERROR indicates that the slave process is creating an error transaction. In this case, an error or a conflict occurred while the slave was pushing deferred transactions to the remote site.
SCHEDULE TXN indicates that the coordinator process is determining the order that transactions are applied and assigning slave processes to execute the transactions.
|
XID
|
VARCHAR2(22)
|
If the session is a slave session, then indicates the transaction id of the transaction that the slave is currently propagating. |
SEQUENCE
|
NUMBER
|
If the process is a slave process, then the sequence number of the calls propagated in the current operation, if relevant. Each transaction must process one or more calls, and the value of SEQUENCE starts at zero and increases as each call is processed. So, the SEQUENCE value shows the call that is currently being processed in each transaction. This value increases until the slave has processed all of the calls in a transaction. |
