How do I migrate OpenIG 4 scripts from using blocking APIs to non-blocking APIs?
The purpose of this article is to provide information on migrating existing OpenIG 4 scripts from using blocking APIs to non-blocking APIs. Moving to non-blocking APIs guarantees an efficient use of resources and can prevent deadlock situations. You should also migrate your scripts if you have upgraded to OpenIG 4.5 or later, or are planning to upgrade in the future; otherwise you will likely encounter a "Cannot execute script" error when trying to run an existing script.
