WARNING
This sample will delete files from your Input and Output FRS. It is strongly recommended that you make a backup of your FRS before running it.
Also - you
MUST run this sample with an administrator user. It detects orphaned objects by querying for them. If the user you run it with is not the administrator - they it may not have rights to see the object and it will delete the associated file.
EXTRA NOTE: Due to how objects in the recycle bin are handled by Enterprise, this sample will not detect recycled objects as valid and will delete the associated files. It is strongly recommended that you empty the recycle bin before running the sample.
How It Works
This sample recursively loops through all directories in the Input and Output FRS. When it finds a file, it assumes that the name of the folder it is contained in is the SI_ID of the associated object. It then queries the Enterprise server for any object with the same SI_ID. If one does not exist, it then deletes all files in the folder and flags the folder for deletion.
This code is designed to work with BI 4.1 and BI 4.2
How to Use It
- Copy the code pasted at the bottom of this blog into a jsp page and copy that jsp page into the folder C:\Program Files (x86)\SAP BusinessObjects\tomcat\webapps\AdminTools
- Edit the code and change the values in the following section:
Boolean Run_In_Test_Mode = true; If set to true, it will just list the files it would have deleted, but won't actually delete them.
If set to false, it will list the files and actually delete it. By default this is set to true.
Note: true and false are Case Sensitive. You must use the values of "true" or "false". Do not use "True" or "False"
String pathToInputFRS = "C:\\Program Files (x86)\\SAP BusinessObjects\\SAP BusinessObjects Enterprise XI 4.0\\FileStore\\Input";
String pathToOutputFRS = "C:\\Program Files (x86)\\SAP BusinessObjects\\SAP BusinessObjects Enterprise XI 4.0\\FileStore\\Output";
This is the path to the FRS folders. Because this is java, all slashes must be double slashes and there should not be a slash at the end of the file path.
String fileToLogTo = "C:\\Program Files (x86)\\SAP BusinessObjects\\tomcat\\webapps\\AdminTools\\TestOutput.txt";
This is the path and filename of the logging file it will create. If the file already exists, it will append the new logs to the end. It will not over-write the log file.
// User Credentials
String username = "Administrator";
String password = "Password1";
String cmsname = "localhost";
String authType = "secEnterprise";
The logon credentials for the Enterprise server. You MUST use the Administrator user for this. The script requires the ability to verify if an object exists. If the account does not have the rights to see the object, it will assume it does not exist and delete it.

// The logic used is:
// - Is there a file? If not, is there a sub-folder.
// - If there is a sub-folder - then go into it
// - If there is a file - then look at the last folder name - that will be the SI_ID
// - Check if an object with that SI_ID exists. If it does - all is well - if not - flag for deletion
// - The deletion will go up folder by folder until one of three conditions occur.
// - 1. A file exists in the folder.
// - 2. More than 1 sub-folder
// - 3. The name of the current folder is either Input, or Output
