SQL
On the Dbvisit Replicate console the replication can be monitored:
Progress of replication: total/this execution
------------------------------------------------------------------------------------
SCOTT.AVI_OBJECTS/scott.avi_objects:100% Mine:2000/2000 Applied:2000/2000
------------------------------------------------------------------------------------
1 tables listed.
dbvrep>
(not all columns are displayed above)
If the replication shows 100%, then it is fully replicated. If the progress is not shown on the command console then LIST PROGRESS can be used to display the progress.
The insert script can be repeatedly run to insert more records which are then automatically replicated to the
MySQL database.
The Mine and Apply processes are run in the background and can be viewed with ps
$ ps -ef | grep dbvrep oracle 4098 1 6 14:27 ? 00:01:17 dbvrep APPLY or –daemon --ddcfile
/home/oracle/orcl/orcl-APPLY.ddc start APPLY oracle 4107 1 6 14:27 ? 00:01:16 dbvrep MINE orc –daemon --ddcfile
/home/oracle/orcl/orcl-MINE.ddc start MINE
MS SQL Server replication
In all replications, the source database must be an Oracle database. Therefore, two-way replication with MS
SQL Server is not supported.
ODBC connection is used to connect to MS SQL, thus a DSN (Data Source Name) must be set up by the system administrator first (e.g. by the ODBC Data Source Administrator tool included in MS Windows).
Currently, no DDL replication is supported for MS SQL.
Example DDC file settings
DDC file 1-way replication example:
The following DDC file settings shows an example of a 1-way replication process.
The source server is on Linux server:
The target is on Linux server:
The TNS names for the source database is: orcl
The TNS names for the target database is: test11202
There is no fetcher process.
