Following from Brendan's recent post on the new WRC UI (https://community.intersystems.com/post/new-wrc-customer-interface), we have put together a fairly short (9 minute) video that steps you through the different pages of the interface and shows you how to use the various features for sorting, filtering and exporting data.
It has been noticed that some customers running JAVA programs (for example, FOP) on AIX would see the server eventually running low then out of memory. Customer would notice the system pages heavily and user experience becomes bad. And the server would crash when out of memory.

While Studio and Atelier are useful development interfaces, there are occasionally situations where a quick edit needs to be made to code and only terminal access is available. A useful set of tools to do this are the zload, zprint, zinsert, zremove, and zsave commands. These are abbreviated to zl, zp, zi, zr, and zs respectively. While each of these commands has its own page in documentation, this article will synthesize that information with examples to provide instruction for their combined use.
