Hi, if a variable is created in script using the VAR statement, and this script is run using a ticker trigger, will this cause a memory leak? Would it be better practice to create the variable just once in the publication properties, rather than create it each time the script is run?

Many thanks, Kurt

A single variable will use a fixed amout of resource when it is allocated. If it is used with a ticker, the variable is just re-used, so it should not create a 'memory leakage' problem. If you create a new variable each run of the ticker...var1, var2, var3, then it will use increasing amounts of memory.


Other things about tickers...... What you do have to be careful of is having a ticker run so fast it uses an unnecessary amount of resources. Opus will eat system resources (processing power) if you have a lot going on.
You have to also bear in mind if you are accessing a database from a ticker, it may take longer for the database to respond that the ticket time, Opus will not know that a response is expected, so you should test for a response.
If you put a 2 second delay in a 0.1 second ticker, Opus will wait for the 2 second delay, so the ticker will not be able to run at 0.1S.
Choose a ticker value time is just as long as it needs to achieve what it does, but not much faster. If the actions/script is longer than the ticker time, then that will determine the time.
If the programming/delay is just a wee bit longer than the ticker time, the ticker will not simply start the next period as soon as it can, it will wait until the start of the next ticker period....if you follow?

....how to be a ticker bore in one easy lesson!!

That's great, thanks Sandy, I use the same variable for every tick, so it shouldn't be a problem, although I will tidy up the script later.

Many thanks, Kurt

Hi Sandy,

I have not been on for a long time but the last time I was on, you were helping me. I see nothings changed.

Your "lessons" are much appreciated and always welcome.

Your not a bore!!

I'm still alive and................ticking........and my jokes never get any better!!
