Does anyone know if there is a limit on the size attachments that can be added to a Work Item and if so what that limit is and if it is configurable?
Thanks, Jerh. |

Hi,
this new TechNote describes how to perform this change: http://www-01.ibm.com/support/docview.wss?uid=swg21641142 Warning: before increasing this value to a higher value, as an administrator, I recommend that you 1st evaluate the possible drawbacks of accepting such heavy attachments in the repository, especially its possible (bad) effect on the DB size and the Jazz server performance.

Note that attachments are very hard to clean up. If there is any reference to the attachment it will not be actually deleted. (and there is no UI mechanism to see what is referencing a file)..

TechNote is very useful. In some cases is important to be able to attach large files. A good practice through review suggest to the owner that the workitem to complete the task remove the attached file, if it is no more necessary. Cleaning is effective in the database when we exclude ?

I do not know. if there is ANY reference to the attachment (its use count is >0) , it will not actually be removed. there is currently no user/administrator method to find references, or see the reference count for an attachment.
AFAIK: 3.0RC0 "What's new" states the space is freed from database. But actually, as mentioned in this forum post, it would actually depend on your client (Web vs. Eclipse). Please check this RFE.
Hope this helps. Regards, Stéphane
well, I just used V4.0.1 (and 4.0.3) to 'remove' an attachment I added to a workitem.
@Sam: what you just depicted would be consistent with the RFE I pointed out previously IF you used the Web client (not the Eclipse one). Do you confirm ?

altho I am admin, and I have enabled the Delete Attachment permission on this project, I do no see 'delete' attachment as an option anywhere (or delete history) as the RFE mentions.
For clarity, let me provide this screen shot (from RTC 4.0.3) obtained by right-clicking on the Attachment itself:

downloading the 4.0.3 client, do NOT see delete with the 4.0.1 client.
ok, I can now confirm, with the 4.0.3 Eclipse client you can forcibly delete attachments
Glad to hear this.

At present, the limits are the minimum of:
* The amount of free space on the disk where attachments and files are temporarily stored during uploading * The maximum size of a BLOB column in the database In practice, this is one GB. James |

Hi Jerh,
You can also reference this topic in the information center: http://pic.dhe.ibm.com/infocenter/clmhelp/v4r0m3/topic/com.ibm.team.workitem.doc/topics/t_creating_work_items_web.html. Step 3 describes changing the attachment size limit. Thanks, Jenn |
