SSL/TLS in CONNX Stages

You can enable the CONNX origins to use SSL/TLS to connect to CONNX.

On the JDBC tab for the stage, select the Use SSL property.
If the CONNX certificate is signed by a private CA or not trusted by the default Java truststore, create a custom truststore file or modify a copy of the default Java truststore file to add the CA to the file. Then configure Data Collector to use the modified truststore file.
1. Use the following command to set the JAVA_HOME environment variable:
```
export JAVA_HOME=<Java home directory>
```
2. Use the following command to set the SDC_CONF environment variable:
```
export SDC_CONF=<Data Collector configuration directory>
```
  For example, for an RPM installation use:
```
export SDC_CONF=/etc/sdc
```
3. Use the following command to copy the default Java truststore file to the Data Collector configuration directory:
```
cp "${JAVA_HOME}/jre/lib/security/cacerts" "${SDC_CONF}/truststore.jks"
```
4. Use the following keytool command to import the CA certificate into the truststore file:
```
keytool -import -file <certificate> -trustcacerts -noprompt -alias <alias> -storepass <password> -keystore "${SDC_CONF}/truststore.jks"
```
5. Define the following options in the SDC_JAVA_OPTS environment variable:
  - javax.net.ssl.trustStore - Path to the truststore file on the Data Collector machine.
  - javax.net.ssl.trustStorePassword - Truststore password.
  Modify environment variables using the method required by your installation type.
  For example, define the options as follows:
```
export SDC_JAVA_OPTS="${SDC_JAVA_OPTS} -Djavax.net.ssl.trustStore=/etc/sdc/truststore.jks -Djavax.net.ssl.trustStorePassword=mypassword -Xmx1024m -Xms1024m -server -XX:-OmitStackTraceInFastThrow"
```
  Or to avoid saving the password in the export command, save the password in a text file and then define the truststore password option as follows: -Djavax.net.ssl.trustStorePassword=$(cat passwordfile.txt)
  
  Then ensure that the password file is readable only by the user executing the export command.
6. Restart Data Collector to enable the changes.
