Connect_Timeout=minutes

    Specifies the maximum number of minutes that the LCS process on
    the master database waits for a network connection to the LRS
    process on the standby database.

    Applicable to:              Master database
    Required or Optional:       Optional
    Default Value:              5 minutes
    Minimum Value:              1 minute
    Maximum Value:              4320 minutes (3 days)

    When you start replication on the master database (before
    starting it on the standby database):

    1. The Hot Standby software invokes the log catch-up server (LCS)
       process on the master database.

    2. The LCS process invokes its corresponding network AIJSERVER
       process on the standby node.

    3. The AIJSERVER process attempts to create a network connection
       to the LRS process on the standby node.

    By default, the LCS process allows 5 minutes for the AIJSERVER
    to connect to the LRS process. You can override the default
    by specifying the Connect_Timeout qualifier when you start
    replication on the master database. (Note that if you specify
    the Connect_Timeout qualifier, you must specify a time value (in
    minutes).)

    The Connect_Timeout qualifier is useful when you start
    replication operations on the master database before you
    start replication on the standby database. This is because the
    Connect_Timeout qualifier allows sufficient time for the network
    connection to be made before the LCS process begins sending
    after-image journal records across the network.

                                   NOTE

       While the LCS process on the master database waits for the
       replication activity to begin on the standby database, users
       and applications can continue to access and modify data in
       the master database.
