Hot Backup Slave Server Configuration

The slave server must be defined. The hot-backup utility is used for this purpose and can be run from the dm or another account.

To configure the Hot Backup Slave Server:

  1. Log on to the dm account.

  2. Run Hot Backup. Enter:

    3. hot-backup

    The Hot Backup Main Menu displays.

  3. Select the Special Operations option.

    4. The Special Operations menu displays.

  4. Select the Setup Server option.

    5. The Setup Server menu displays (on the right side of the screen).

  5. Select the New Server option.

    6. The Setup Server utility displays (on the right side of the screen). This is the same menu that was used when creating the master server.

  6. Enter the appropriate value for each of these fields:

    7. Server Name

    Name for the slave server. Can be any alphabetical string up to eight characters.

    Server Type

    Specifies whether the server is to be the Master or the Slave server.

    • M = master

    • S = slave

    Type S for slave.

    Remote Host name

    For master servers only.

    TCP port number

    TCP port number, from 1024 to 32767, of the associated slave server. The default is 2000.

    NOTE—This should be the same port number defined on the master server.

    Target VME name

    For master servers only.

    Protocol

    inet. Cannot be modified.

    Log slave update

    This option is for Hot Backup implementations that employ multiple cascading servers. If set to ON, all updates received by the slave are logged in the transaction log queue, to be sent to another system. If set to OFF (default), the updates are not enqueued.

    Check period

    For master servers only.

    TxLog timer

    For master servers only.

    Notify list

    List of D3 users (as defined in the D3 users file) or D3 port numbers to notify in case of error, separated by commas. The port numbers are expressed in a syntax similar to the TCL command msg. For example, to notify the users dm and bob, and line 0 (regardless of whether it is logged on):

    dm,bob,!0

    Apply updates

    Instructs the slave server to apply the updates it receives from the master server immediately (ON) or delay them (OFF) until it receives an explicit command. Normally, this option should be set to ON.

    NOTE—When the slave server starts, it reports the status of this option. Applying updates should not be disabled long, since the slave and master databases can be become out-of-sync when updates are not applied.

    Auto create

    Automatically creates any missing accounts and files on the slave server.

    NOTE—It is a good precaution to leave this option set to ON.

    Comments

    Any comments.

  7. Type Y to confirm your changes.

    8. NOTE

    You can also type N to return to the above menu to make additional changes, or Q to quit without saving your changes.

    The slave server is configured.
