Currently if you want to change the BO server parameter, such as adding “-trace”, you have to log on to CMC, open the Properties dialog and do the change there. In some cases, the users will limit the usage of CMC. It means sometimes they will want a way do to this changing without CMC. To achieve this, we can use BO SDK to create a program and use the program to change the command line.
Below is a simple java sample code. The logic is quite simple. First reading the input to get the user info to log on the system. And run a CMS query to get the infoobject of the Server. Then, using the interface IConfiguredContainer and IExecProps to read and write the command line parameter.
- In this sample, the input from the command line is as the below format:
-cms <cms> -username <username> -password <password> -serverid <serverid> -authentication <authentication>
Parameter authentication is optional. If no input it will use secEnterprise. Parameter serverid is the SI_ID of the server which you want to perform the change.

To run this code, you will also need to include the basic jar files, such as: cecore.jar, celib.jar. cesdk.jar, cesession.jar and etc. All the jar files can be found in the BO installation folder as the following path in a windows installation:
<bo installation>\SAP BusinessObjects Enterprise XI 4.0\java\lib
