    Task Attachments

    (jerome_dinnat) Level 1

      Am I right if I think the task attachment of a process are saved in the GDS of the application server ?

      Is there a way to purge the task attachments where there are no more needed ? (even using the java api)

      Because the GDS will grow up to big.

      Thank you.

          I don't know if there is any other location that task attachments are stored but I do know that you can find them in the table tb_task_attachments as BLOB entries.

            Hi josh,

            Thanks for the reply. I saw this table but I will explain you my issue.

            In a process, my users need to attach sources to the Workflow. The attachments are next copy in a directory on a server.

            I was wondering what happen if big attachments are added. So I added a zip file from 1Go to the form. The file was good copying in the directory I want and the process terminated good.

            I saw the tb_task_attachments and look at it size. The size is 0.274MB for 73 row. So I think the attachments was saved in an other place. (but I see the [content] blob entries you mentioned. Is the file compressed or a reference to the file ?)

            I checked in the /jboss/server/all/svcnatives/documentStorage and find my file of 1Go in a directory.

            So I am asking me if several users add big attachments, my GDS will grow up to big. How can I delete the attachement from the GDS without delete process instance.

              I read that the big attachments are not stored in the database but in the GDS. There are permanent document so they will never be deleted.

              If I delete them manually or by a Java program, I suppose Livecycle will crashe.

                Hi Jerome
                We have developed a utility to remove large attachments, and several other LiveCycle data objects that consume database/GDS space.
                You can download a trial here:
                http://www.avoka.com/avoka/addons.shtml - click on "Purge Utility".

                By the way, attachments are stored as "Documents", which mean that they follow the same rules as other types of documents - they are stored in the database till they exceed the threshold (64K by default), and thereafter they are stored in the GDS.

                  Hi Howard,

                  I saw your solution, you have a lot of very interesting utilities on your web site but unfortunately I can't use a non-free solution.

                  I try to find an other way to upload files from my user to a folder server.

                  Thanks for the help.

                    Hi Jerome

                    I found your response very interesting...

                    Without meaning to query your decision, can you explain why you can't use a "non-free solution".

                    It seems to me that you've already spent a lot of money on LiveCycle, so you've already commited to using a "non-free solution".

                    Why not spend a bit more and end up with a solution that solves all your problems?

                    Instead you seem to be about to spend a whole lot of time and effort to come up with a solution for a problem that we've already solved. Isn't your time also worth something? For the record, it took somewhere around a man-month of effort to build the purge tool, by a developer who already had a whole lot of experience with LiveCycle - and you can buy it for the price of a few days of your time.

                    I would very much like to get an understanding of your reasoning, and look forward to your response.

                    Many thanks,

                      It's possible to delete attachements with the TaskManager API :

                      TaskManager taskManager = TaskManagerClientFactory.getTaskManager(_Factory);

                      taskManager.deleteAttachment(TaskID, AttchID);


                      I never tested it but suppose that it will delete the document from the GDS.



                      I've juste tested id and and unfortunately it does not Work !

                      The function only delete the line in the Database but not the document in the GDS!

                      Isn'it a bug ??
