Email plugin registration fails on occasion

[BrentHedden]

I've got a scheduled script that runs every 15 minutes that checks a queue for unsent emails, and sends them out as needed.  Since this is on FMServer, I have to register the plugin with each ititeration.  

When the server was on a MAC, it would on occasion, not register (which exits out of the scrip).  When this happens, I get an email every 15 minutes until I restart the FMSE service.  

Now that this is running on a Windows server, it still happens, but not as consistently as before, and It doesn't continually happen, so I don't have to restart the FMSE service.  Using the latest version of both the plugin and Java.  Is there a way to permanently register this plugin on a server so that it doesn't have to keep registering with each ititeration?

The FM error that is returned is simply       ERROR     with no further explanation.  Looking at the LogFile that it creates, it looks like it's trying to run in demo mode?? Here is a snippet of the file from a time that recently error out on me -

No, there is not a way to permanently register the plugin on FileMaker Server. The reason is because whenever a script is run on FM Server it is essentially like you opened FileMaker Pro, ran the script, and closed FileMaker Pro. This being the case, every script gets its own instance of the plugin. Every plugin instance is in demo mode by default unless it sees that the FMSE has been running for >2hours. If it has you get demo mode timeout errors. 

With that being said, you should not get a demo mode error when calling the registration function. I will see if I can reproduce that error. For the time being, I have had success in the past by having the registration function call twice in a row. It is not the most elegant workaround but I believe it should fix the issue while we track down and fix the bug. Try that and let me know if you continue to have issues.

Couldn't a file be created upon first registration that later instances can look at and verify?  I've seen this method being used by some other plugin vendors.

 

Calling the registration twice in a row seems to have done the trick.  Since implementing this, I haven't gotten a single error message. Thanks for the heads-up!
