Managing connectors on remote data sources

You can start and stop connectors on remote data sources.

Before you begin

Procedure

On Linux® and Mac OS, to start the remote connector, follow these steps.
1. Go to the directory where you installed the remote connector.
  For example, /home/user1/dvendpoint.
```
cd /home/user1/dvendpoint
```
2. Run the following command to start the remote connector.
```
nohup ./datavirtualization_start.sh
```
On Linux and Mac OS, to stop the remote connector, follow these steps.
1. Go to the directory where you installed the remote connector.
  For example, /home/user1/dvendpoint.
```
cd /home/user1/dvendpoint
```
2. Run the following command to stop the remote connector.
```
./sysroot/killGaianServers.sh
```
On Windows, to start the remote connect, follow these steps.
1. Start the Windows Services Manager console (services.msc).
2. Locate the remote endpoint service.
  For example, the service will be named DataVirtualizationService6414.
3. Start the connector.
On Windows, to stop the remote connector, follow these steps.
1. Start the Windows Services Manager console (services.msc).
2. Locate the remote endpoint service.
  For example, the service will be named DataVirtualizationService6414.
3. Stop the connector.
To change the default memory setting that is used by the remote connector, follow these steps.
1. Stop the remote connector.
2. Set the JAVA_OPTS parameter.
  The following example changes the memory setting from the default value of 256 MB to 512 MB.
```
export JAVA_OPTS=-Xmx512m
```
3. Start the remote connector.
On Linux and Mac OS, to change the default port (6414) that is used by the remote connector in an already generated dvendpoint.sh script, follow these steps.
1. Stop the endpoint that is running and restart it, providing the new port as a parameter.
  See the following example.
```
datavitualization_start.sh -p 6415
```
On Windows, to change the default port (6414) that is used by the remote connector in an already generated dvendpoint.bat script, follow these steps.
1. Stop the endpoint that is running.
2. Install a new remote endpoint service that uses a new port. From the installation directory, run the following command.
```
install_dv_service.bat -p 6415 > dvendpoint.log
```
  This command creates and starts a new endpoint service DataVirtualizationService6415 that uses port 6415.
