The Locktable in CACHE (from the programmer prompt)

Download PDF

There are three (3) ways to get into the LOCK table at a Cache site.  Those are – the System Portal, the Cache Cube (in older versions of Cache) and at the programmer prompt in the %SYS namespace or UCI.

This document outlines the steps to do everything without the cube or portal.  You need to be in the “%SYS” UCI so you would ZN “%SYS” to move to that UCI.
