you could e.g. override the init(PMContext) method in your
DatabasePersistenceManager derived class as follows:

    public void init(PMContext context) throws Exception {
        super.init(context);

        if (externalBLOBs) {
            /**
             * store BLOBs in a sub directory of the workspace's
             * virtual file system
             */
            BasedFileSystem blobFS = new
BasedFileSystem(context.getFileSystem(), "blobs");
            blobFS.init();
            this.blobFS = blobFS;
            blobStore = new FileSystemBLOBStore(blobFS);
        }
    }

however, i have difficulties understanding your requirement. could you please
elaborate why you need to locate the workspace home directories outside
the repository home dir?

cheers

Re: Blob in another directory

Hi Stefan,

At this time, I am only doing some tests for big repositories and one of 
the requisites is distributed workspaces. I need to store data in 
different hard drives, if I use internal blob's, it works.
I still not sure which is better: internal or external blob ;-)
