What is the size limitation for an attachment in RTC
I am curious to know 2 things
1) What is the limitation of a single attachment / multiple attachments that can be enabled with a single work item and Also is there any size limitation applicable also to source code management as well 2) How are attachments stored in Backend database . Is it stored as blob for db2 , but the max limit of blob data type is 2 GB and if that is the case how is it possible to store files greater than 2 GB , does it do a split and store ? Thanks & Regards Jagadish |

1) What is the limitation of a single attachment / multiple The default size limit for an attachment is 50MB. This value can be configured in the Admin Web UI. I don't know the details about SCM, but the limit is certainly higher. 2) How are attachments stored in Backend database . Is it stored as Attachments are stored in the repository, and we don't provide a split option for them. If you have many of these huge files, it might be a better option to not store them as attachments in the repository but to store them somewhere else. You can then add a 'Related Artifact' link to the work item that points to the attachment location. -- Regards, Patrick Jazz Work Item Team |

Hi Patrick,
Thanks a lot , I was able to configure it to a higher number and use, but is there normative guidelines on how to handle bigger files in team concert , should the team be using external tools like content managers / filenet or RTC is capable of handling files which are in the range of 80 ~ 150 MB (This are basically video files) or binaries Thanks & Regards Jagadish 1) What is the limitation of a single attachment / multiple The default size limit for an attachment is 50MB.

Thanks a lot , I was able to configure it to a higher number and use, I am not aware of any normative guidelines, but files in the 100MB range shouldn't be an issue. I was more concerned about the 1GB+ files that you mentioned. To my knowledge, SCM has put considerable effort into managing very large files, but work item attachments are more geared towards the use case of attaching documents, screen shots, logs etc. to work items to help it's owner investigate a bug. If videos fall roughly into this category, I don't see any issue. Using RTC Work Items as a media asset management system would not sound quite right to me, though. -- Regards, Patrick Jazz Work Item Team |

Hi,
strange enough to revive this 4-years-old thread... but this blog post: http://sleroyblog.wordpress.com/2013/09/05/recommendations-educated-guesses-for-clm-limitations/ provides currently known (*) CLM/JTS/RTC/RQM/RRC limitations plus some "educated guesses" on sizing aspects. Regards, Stéphane (*): at this date. |
