OS: Windows XP
Toolkit: 6.1.0.5
Basic setup: Usual number of flows & ESQL doing good things assembled in a project. A separate project, referenced by the first, contains an ESQL file with common functions to parse policy numbers, determine renewal dates & status codes, usual stuff. Both projects use the same named, non default namespace & schema path.
Problem: One flow (out of a dozen) won't deploy after being edited throwing a BIP2558E Undefined Function error, naming one or other of the common functions in the referenced project as being not defined or in the schema path.
If nothing is done except Project->Clean->Clean Selected Project then the deploy goes through without a whimper. Until the next change when it fails and needs to be cleaned again.
No other flow in this project exhibits this behavior. Each will deploy unless the idiot writing the ESQL has made a mistake, no cleaning necessary. This flow used to do this before my Toolkit crashed with an out of memory error while editing it.
Before I burn this flow to the ground and recreate it, does anybody have any less destructive ideas about what's broken and how to fix it?

I know what you mean. I've had chaffing and irritation too in that area. I found that less starch in the undies helps.

Did anything more technical help?

We've now fully cut-over to automated builds, so we do not build or deploy BAR files through the toolkit anymore. A common step in our automated build process is deleting the workspace/class files, which is effectively a "Project Clean". We currently use CruiseControl/Ant as our build tool but rumor has it that we will be adopting a commercial build appliance next year. Using automated builds, we do not encounter the toolkit problems any more. I'm sure IBM may be working on a patch to solve the toolkit issues for the next fixpack. Hudson is also a nice tool, if you care to look at it.

Take a look at Maven for bar file builds. IMHO it workds better than other tools I've seen.
We are moving over to it for all deployments beyong the 'DEV' Environment. Hudson has a place as well mostly for automated & continuous testing in UAT environments.

I've used Hudson on previous sites and it is cool.
This is a bit earlier in the development cycle than is sensible for automated builds; the code's likely to be experimental and subject to rapid change. Also the site really doesn't have the volume or infrastructure to support automation.
So where did I put those matches.....

One other tip. First thing every morning, I come in, sit down, and authenticate to the firewall. Then I create a new directory on my C drive, and check out the tip revision of the source code into that new directory. I open toolkit and point toolkit to that new directory, which causes toolkit to reinitialize everything from ground zero every day. This technique seems to reduce the frequency of toolkit malfunctions and it ensures I am working with the latest code from my partners in crime.
For example my root directory for toolkit is C:\Documents and Settings\<username_or_id>\wmbt700
In this root, each day I create a new folder, called Release2_Sep22 or Release2_Sep23 or Release2_Sep24
I then double-click on that folder so to be inside it and right click to bring up the SVN menu, select SVN Update command, and wa-la, all the latest source code appears.
Open toolkit, point to the new directory as the new workspace, say C:\Documents and Settings\<username_or_id>\wmbt700\Release2_Sep24 and hit File -> Import -> General -> Existing Projects Into Workspace.
This starts you out fresh every time.

Do you have Build Automatically enabled or not?
It sounds like a build order issue, where the flow in question is being built out of order for some of it's dependencies.
Also... probably should push up to 6.1.0.8...  |

Any way to enforce or reset this?

Probably. I am working on it but the political will is lacking.

I'm using MB v7.0.0.0 on XP and this version seems worse than 6.1.0.4 for this. I routinely do a clean before I build within the toolkit. Otherwise, I get really wacky errors... everything from undefined functions in the ESQL or flows to errors about our Java JARs having ClassNotFoundExceptions and stuff.
I also have Build Automatically set.
The only reason I haven't issued a PMR on this is because I know FP1 is out for MB v7. We've got a list of weird things we've seen in this version (flows disappearing from the Broker view, but they are really still there) and I want to see if the next fixpack resolves that.
I agree with mqjeff, the upgrade to MB 6.1.0.8 might help. I'm hoping if there's a fix in the MB 6.1 line for stuff like this that fp1 or 2 for MB 7 may contain a similar fix.
We also use an Ant-based build for our Stage and Production environments and this rarely gives us these kinds of errors. So, I agree with the others that an external build procedure might help.
Anyway, sorry I cannot give you an answer, but wanted to just chime in to say that you aren't alone. |

It always helps to be in a group.

Is there any chance you've changed BUT NOT SAVED the file that contains one of the resources that aren't being found?
ccrandall - there are a number of fixes for toolkit build issues in 7.0.0.1 vs. 7.0.0.0. You may be seeing incidents of
http://www-01.ibm.com/support/docview.wss?uid=swg1IC66635
Notice that is fixed in at least iFix 02 of 7.0.0.0, so you might just make sure you're at the most recent iFix of 7.0.0.0 if you don't want to run along to 7.0.0.1 while you're at it.
Most of the APARs that might apply that are fixed in 6.1.0.8 here appear to be already fixed in 6.1.0.5, but it's still worth a spin. |

Not the slightest.
Even if I had failed to save, how come the clean allows a deploy?

Try creating a new workspace and importing the relevant projects.
Try closing and opening the relevant projects.
As I said, it kind of sounds like a build order issue or an issue where files are not marked as dirty when they should be. I'm not aware of any practical workaround for either of those.
There are a number of apars in 6.1.0.8 toolkit as mentioned, at least some of them may apply. |
