See the TIPS below for handy common Dbvisit Replicate tips.

The replication can be viewed from the Dbvisit Replication console. 

1. Switch to the session where the Dbvisit Replicate console is running and the replication can be seen to be progressing while Swingbench is running in the background. 

\ Dbvisit Replicate 2.7.02.4333(MAX edition) - Evaluation License expires in 30 days
MINE IS running. Currently at plog 133 and SCN 3214278 (08/01/2014 06:17:57).
APPLY IS running. Currently at plog 133 and SCN 3214206 (08/01/2014 06:17:55).

7 tables listed.

In the above console line numbers are shown for clarity and each line number relate to the following explanation:

  1. Shows the version number and the edition
  2. Shows the MINE process is running. Which PLOG sequence (which is the same as the redo log sequence) and SCN the MINE is processing and the database time related to the SCN
  3. Shows the APPLY process is running. Which PLOG sequence and SCN the APPLY is processing and the (source) database time related to the SCN
  4. Name of the replication
  5. Separator
  6. Replication statistics for table OE.CUSTOMER. The replication is at 99%. 1138 records have been mined. 1133 records have been applied. There are 0 conflicts.
  7. Replication statistics for table OE.ADDRESSES. The replication is at 99%. 1138 records have been mined. 1133 records have been applied. There are 0 conflicts.

TIP 1

If the Dbvisit Replicate console is not running then:

  1. Connect to the souce server (dbv01) as oracle.

  2. Cd to the correct directory.

    cd ~oracle/dbvrep_orcl

  3. Start the Replication console:

    ./start-console.sh

  4. The console can also be started on the target server *. The manual command to start the console is: 

    dbvrep --ddcfile /u01/oracle/dbvrep_orcl/dbvrep_orcl-APPLY.ddc

    * The console can be started on any server that has a TNS connection to both the source and target database, and has the Dbvisit Replicate software installed (including Windows or the host machine). You will need to copy either the MINE ddc or APPLY ddc file to the server you are running the console from. This is to connect the console to the replication.

TIP 2

If there are many tables in the replication, then only a certain number of tables will be shown in the console.

The number of active tables shown in the console is configurable with setting "STATUS_BAR_ACTIVE_TABLES".

To get a list of all the tables in the replication, use the command:

dbvrep> list progress

The "list progress" report can be emailed automatically if notification is setup. The schedule when this report is sent is controlled by "NOTIFY_DAILY_LIST_PROGRESS_TIME24"

TIP 3

The statistics of the replication can be viewed with the following commands:

dbvrep> list stats
dbvrep> list stats all
dbvrep> list stats OE.ORDER_ITEMS

TIP 4

There are many settings and configurations possible with Dbvisit Replicate. To see all the settings type: "show all"

For example, to see all the settings regarding notifications:

dbvrep> show notify                                                                                                                          
*.NOTIFY_ALERT_EMAIL = OFF
*.NOTIFY_ALL_EMAIL = OFF
*.NOTIFY_CONFLICT_CURRENT_PAUSE = YES
*.NOTIFY_CONFLICT_CURRENT_RETRY = 2
*.NOTIFY_CONFLICT_THRESHOLD = 100
*.NOTIFY_DAILY_LIST_PROGRESS_TIME24 = 0700
*.NOTIFY_EXCEEDED_CYCLE_NUM = 2
*.NOTIFY_INCIDENT_LIMIT = 10
*.NOTIFY_INTERVAL_BETWEEN_CHECK = 5m
*.NOTIFY_ON_DDL = YES
*.NOTIFY_PEER_DOWN = ALL
*.NOTIFY_PROGRESS_DIFFERENCE_PERC = 10
*.NOTIFY_SCN_DIFFERENCE = 1000
*.NOTIFY_SEND_HEARTBEAT_TIME24 = 0800:1300
*.NOTIFY_SEQUENCE_DIFFERENCE = 10
