Re: [SR-Users] Difference between shared and script variable

Hello, $shv(...) is referred as shared memory variable because it stores the value in shared memory. That means if you set $shv(x) in one process, you can read its value from another process. You have to be sure you don't have races in setting the variable, that could be achieved with locks from cfgutils. $var(...) is referred as private memory variable because it stores the value in private memory. That means its value is valid in the context of the same process (e.g., use it while processing the same sip message on a single routing block type, like running the main request route block, or reply route block, etc). It is not safe to use it for transactions, like setting it in request route block and reading it in failure route block (use avps for that case). $var(...) is faster to use and does not need locking at all. These are usually referred as script variable, but this term can be confused with all the config file variables.
