Yes. Can easily live with that. Greatly appreciated

QQ. How do you specify within Groovy which SageTV Server to use?
Since I have multiple SageTV Servers running

Grab the javadocs for sagex and lookup SageAPI.setProvider(); you'll want to pass it an instance of RMISageAPI with the host or IP of the Sage server you want to force sagex to connect to.

I just reinstalled sage onto windows 8. I copied over my stuff from before to do comskip, but I'd like to have restart the service nightly and also do backups. Before I had batch files/windows scheduled tasks to do that.

One thing I see is that even with UAC off and the account an administrator, I cannot launch a batch file with elevated privileges...it won't let me start/stop the sage tv service. How do you guys get around that?

And would anyone be willing to share or point me to where I could find some examples for the restart and for the backup?

Here are the SJQ scripts for backing up your SageTV directory:

https://sagetv-addons.googlecode.com...up_test.groovy

https://sagetv-addons.googlecode.com..._backup.groovy

The first is the test script to determine if it's "safe" to shutdown Sage. The second script is the actual backup script. Read the comments in both carefully.

Thanks for the info. Stupid question here but how do I make it execute the backup groovy script? If I just put the script name under the executable option, it won't run it - it says it is not a valid win32 application. The instructions just say "Configure your standalone task client to run this new task." with no further details. The only task I've ever used is comskip which is an executable...never tried to use a groovy script as an executable.

Also one issue I had with the test script is that I may have extenders connected but not doing anything...so simply testing for connection is going to keep it from running. Does anyone have an example on how to test if an extender is actually playing something?

Specifically, the isMediaPlaying() method is probably what you're looking for.

So according to that, you can simply name the file something.groovy and use it as a task executable...that isn't working for me. Does the .groovy file need to be associated with something in windows? ANy ideas how I can fix that?

As it says, when using a groovy script as an executable in a task, you must prefix the script name with script: so SJQ knows to run the script thru its groovy engine instead of passing it to the OS to execute it as a native executable. So when defining your task, you must explicitly define the executable as (literally):

script:C:/path/to/script/full_backup.groovy

Sorry for my reading comprehension failure. Thanks for being patient with me

Well I must be doing something obviously wrong, but I am not sure what it is...

if (Global.isMediaPlaying()) {
println "Something is playing"
return 1
}

Gives this:

Caused by: groovy.lang.MissingMethodException: No signature of method: sagex.api.Global.isMediaPlaying() is applicable for argument types: () values: []

At the top:

com.google.code.sagetvaddons.groovy.api.GlobalHelpers

You're calling it incorrectly. You need to import the GlobalHelpers class and then call:

GlobalHelpers.isMediaPlaying()

Thanks I had tried that and it did not work, but I didn't have the import. With the import now it works:

import com.google.code.sagetvaddons.groovy.api.GlobalHelpers;

Now the test passes but the other script fails with this:

javax.script.ScriptException: org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
Script1.groovy: 179: The class 'BackupMatcher' has an incorrect modifier private

I changed the class to public and it works...but not sure why it didn't work from the original example

The example was written against Groovy 1.x. Recently, Groovy was upgraded to 2.0 and private members are no longer valid in groovy scripts. Changing it to public is the fix. The (generic) issue/fix was discussed somewhere in this thread when the upgrade to Groovy 2.0 was done.

Thank you...everything seems to be working now. I appreciate your help with this

Not if something is playing since I have 1 extender playing live tv (white noise for sleeping) so I check to see if anything is scheduled to record.

    Use this script as the test for the full_backup.groovy script.  Basically this
    script just checks a bunch of conditions to determine if it is "safe" to shutdown
    SageTV and perform the app dir backup.  Remove/add/modify conditions to your needs
    below.
    
    Remember, return 1 to push the task back to the queue, 0 to tell SJQ to run the backup script
    or 2 to tell SJQ to skip the backup.

Haven't upgraded yet...probably need to and check my scripts to make sure they work properly.

Just need to find some "downtime" to work on it without breaking anything.

this has reoccurred and my HD almost filled up again. One other weird thing is that I now cannot get into the SJQ part of the web UI. Everything else in the web UI works but when I try Job Queue, Manage Clients or Manage Events I get no response. But Queue a task and Manage Crontab work ok. I have tried rebooting a few times with no luck as of yet but I haven't tried using the SJQ Sage UI to examine and kill the tasks.

It sounds like there's thousands of jobs in the queue table. That's probably why the web pages aren't responding. I doubt the STVi screens are going to respond either.

Directly connect to the H2 database and clean up the queue. I've never been able to pinpoint the cause of this situation as I've never experienced it myself, but there's obviously a condition that occurs that results in multiple (copies?) of jobs being added to the queue and constantly rerun.

[wayner]

How do I connect to the H2 database? I read this but it doesn't really see to apply?
