Updating IBM Spectrum Control data collector trusted certificates after replacing default SSL certificate for the Device server with a self-signed certificate OR an external certificate

Use the keytool command to update the IBM Spectrum® Control data collector trusted certificates after you replace the default SSL certificate for the IBM Spectrum Control Device server.

If you replace the default SSL certificate for the IBM Spectrum Control Device server, you must update the IBM Spectrum Control data collector trusted certificates or else the data collector does not communicate properly with the Device server.

Log on to the server where IBM Spectrum Control is installed. Ensure that you log on with the appropriate user privileges.
Stop the Device server.
Open the /jre/bin directory where IBM Spectrum Control is installed.
Enter the following command to export the default SSL certificate from the Device server keystore.
For Windows™ operating system, enter the following command:
```
keytool.exe -exportcert -alias default 
-keystore "installation_dir\wlp\usr\servers\deviceServer\resources\security\key.p12" -storetype pkcs12 
-storepass device_server_keystore_password -file deviceServer.cert
```
Where device_server_keystore_password is the Device server keystore password and the default value for this password is default.
For AIX® or Linux® operating system, enter the following command:
```
./keytool -exportcert -alias default 
-keystore installation_dir/wlp/usr/servers/deviceServer/resources/security/key.p12 -storetype pkcs12 
-storepass device_server_keystore_password -file deviceServer.cert 
```
Where device_server_keystore_password is the Device server keystore password and he default value for this password is default.
Enter the following command to delete the previous IBM Spectrum Control Device server SSL certificate from the IBM Spectrum Control data collector trusted certificates.
For Windows operating system, enter the following command:
```
keytool.exe -delete -alias deviceServer -keystore "installation_dir\jre\lib\security\cacerts" -storepass 
data_collector_keystore_password 
```
Where data_collector_keystore_password is the IBM Spectrum Control data collector keystore password and the default value for this password is changeit.
For AIX or Linux operating system, enter the following command:
```
./keytool -delete -alias deviceServer -keystore installation_dir/jre/lib/security/cacerts 
-storepass data_collector_keystore_password
```
Where data_collector_keystore_password is the IBM Spectrum Control data collector keystore password and the default value for this password is changeit.
Enter the following command to add the default SSL certificate from the IBM Spectrum Control Device server to the IBM Spectrum Control data collector trusted certificates.
For Windows operating system, enter the following command:
```
keytool.exe -importcert -noprompt -trustcacerts -alias deviceServer -file deviceServer.cert 
-keystore "installation_dir\jre\lib\security\cacerts" -storepass data_collector_keystore_password 
```
Where data_collector_keystore_password is the IBM Spectrum Control data collector keystore password and the default value for this password is changeit.
For AIX or Linux operating system, enter the following command:
```
./keytool -importcert -noprompt -trustcacerts -alias deviceServer -file ./deviceServer.cert 
-keystore installation_dir/jre/lib/security/cacerts -storepass data_collector_keystore_password
```
Where data_collector_keystore_password is the IBM Spectrum Control data collector keystore password and the default value for this password is changeit.
Start the Device server.
