Teamsite MediaBin imported files locked.

I am having trouble with presentation templates using the iwov_mediabin_import tag getting "Access is Denied" when attempting to write files to Teamsite. This isn' t just a simple permissions issue (I don't think), so stay with me for a minute.

We have MediaBin setup for our DAM, and have Teamsite DCTs which allow users to select files from MediaBin. We have presentation templates setup for the DCRs which import the files into Teamsite from mediabin.

We are running compiling the presentation templates in a perl script called as an externalTask from Workflow. The perl script uses the presentation templates to import the assets (images, pdfs) from MediaBin, and uses the output of the presentation templates to build filelists which are then passed off to OpenDeploy.

This process generally works, although we have been having problems getting OpenDeploy stable. We're working on that separately, but I think it is contributing to the issue.

So, the user can create a DCR with some images associated from MediaBin, and can submit it through workflow which does all the OpenDeploy stuff we want. The problem arises should the user edit the DCR, and redeploy. We are getting into cases where the presentation template is trying to import files which already exist in Teamsite (from the previous import), and rather than doing the right thing, the importation is failing with an error like that included at the end of the post.

This doesn't happen everytime. Normally, the user can reimport/overwrite the files just fine. There seems to be some process locking the files. I can go in to the interface, delete the files, run the deployment again, and everything works just fine. So the problem occurs kind of at random.

We beleive it may have to do with opendeploy crashing and failed deployments somehow leaving these files locked, but we are narrowing down so many issues at once right now, it's hard to tell. We have found that if we restart OpenDeploy, the problem isn't alleviated, however, if we restart TeamSite, the problem is resolved. Users can then retry the importation and everything goes as planned. This leads us to beleive there is some process associated with Teamsite that is locking the files.

We just made some changes to try to stabilize OpenDeploy, and hopefully that will solve our problem, but only time will tell on that. If it doesn't happen for a day, we could be in the clear.

I'm hoping someone out there may have some feedback on this complicated topic.

If you think I'm just a crackpot newbie with some outrageous problem, you're mostly right, but please refrain expressing that opinion too adamantly.

I have gotten this to work in TeamSite 6.1 and 6.5 SP1, have not worked in 6.5 SP2, but it should still work.

Couple thoughts:

- What user id is running this external task process in your workflow?
- What are the permission settings for that folder and workarea?
- Is that external task process completing correctly or are you transitioning your workflow but forgetting to terminate the process that is being invoked?
- Is your external task script a unix shell script, Perl Script, Java Application, etc.

Let me know, hopefully we can get there.

1. I'm not sure who the external task would/should run as. I'll have to research that. Would it be the workflow task owner?

2. The permissions for the folder are read/write for an editorial group(gr_editors), and full control for an editorial subgroup (gr_us_editors) containing a subset of the users in the larger group. The user who is initiating the workflow is a member of gr_us_editors. These groups are local Windows groups with users who are domain users. The workarea permissions are -- Sharing: Group Owner: fncmsprod\Administrator Group: FNCMSPROD\gr_editors

3. I'm not sure if the external task process is completing properly I'll send up a copy of the scripts and see what you think. Everywhere the script encounters an error in the process, it does a Callback(), then exit;

4. The external task is a perl script called from workflow as $iwhome/iw-perl/bin/iwperl.exe scriptname args

I'll get some scripts and stuff posted up Hopefully that will help.

So, I'm going to go crazy here, and post up the files that represent the workflow importation and open/data deploy.

Basically, the process goes like this

1. multideploy.wft calls externalTask to following script
2. extractAndMultOpenDeploy.ipl
iwpt_compile presentation templates to import mediabin assets
builds file lists, then calls openDeploy
CallBack to workflow on errors
3. OD with config GamesRadarDeploy.xml
opendeploy imported mediabin assets
calls a DNR to do datadeploy so everything is transactional and can all be rolled back on failure.
4. DataDeployDNR.ipl
calls DD with config FutureNetFL.xml
CallBack to workflow on error and success

sound complicated yet? It sure feels like it to us, but it generally works. I'm sure there are plenty of things which could have been implemented more cleanly in the files Im going to post, but we are pushing a TIGHT deadline (when is development ever NOT facing a tight deadline), and we are relatively new to Interwoven products. We had some professional services to start, but we are now on our own to get everything working.

Now come the file attachments.
