Once you have Dbvisit Standby installed on all the servers, it is important to make sure that the communication between the primary and standby servers are working. This This can be done by making use of the Dbvnet Test utility provided with the Dbvisit Standby installation - dbvnet-test, which is located under the dbvnet sub directory. When When using the default path, this utility will be in in:
| No Format |
|---|
/usr/dbvisit/dbvnet/dbvnet-test |
To test communication between the primary and standby servers you can run the following recommended test commands:
...
In the example below, dbvlin101 is the primary server and dbvlin102 is the standby server. Dbvisit Standby was installed using default values and no additional configuration has been performed at this stage. Dbvnet Dbvnet and Dbvserver is running on both nodes, but only Dbvnet is required and used for these tests:
...
Test 1: Basic Status Check
| No Format |
|---|
oracle@dbvlin101[/usr/dbvisit/dbvnet]: ./dbvnet-test -s dbvlin102:7890
>>> Determining Dbvnet status on server dbvlin102:7890...
Dbvnet on server dbvlin102:7890 is running. |
...
Test 2: Full Test - 10MB file is copied (and verified) between primary and standby
| No Format |
|---|
oracle@dbvlin101[/usr/dbvisit/dbvnet]: ./dbvnet-test -f dbvlin102:7890
>>> Determining Dbvnet status on server dbvlin102:7890...
Dbvnet on server dbvlin102:7890 is running.
>>> Running file transfer round trip on server dbvlin102:7890...

Dbvnet can be stopped and started using the dbvnetd executable located in the dbvnet sub directory (example - /usr/dbvisit/dbvnet). Below Below is an example of stopping and starting the Dbvnet background processes:
