`OPEN_LINKS_PER_INSTANCE` specifies the maximum number of migratable open connections globally per database instance. XA transactions use migratable open connections so that the connections are cached after a transaction is committed. Another transaction can use the connection, provided the user who created the connection is the same as the user who owns the transaction.
`OPEN_LINKS_PER_INSTANCE` is different from `OPEN_LINKS`, which indicates the number of connections from a session. The `OPEN_LINKS` parameter is not applicable to XA applications. See Also: "OPEN_LINKS".
