[IGNORE: Already AVAILABLE] Provide a high-speed API to materialize info about a specific PTF

The QpzListPTF API and the SQL PTF_INFO VIEW are fine for non-critical applications. However they perform far too slowly for in-App use where the App simply needs to check if a specific PTF has been installed/applied. Today we have to matieralize the entier list of installed PTFs and then search through them to determine whether or not the PTF is installed. While this isn't difficult, it seems to take a longer than necessary duration.

The PTF_INFO VIEW makes that process simple but it too lags in performance due to using QpzListPTF under the covers.

What we need is a new API that allows us to check whether a PTF is installed and/or applied. A list of PTFs would be better, but I'd settle for an API that only checks for one and did so very fast.

    Well... don't I look silly. FIrst, thank you for the QPZRTVFX recommendation. Second,I had this same issue last year and actually wrote my own interface to QPZRTVFX. So I apparently knew about it, but forgot that I had implemented it. LOL! Thanks again!

    The QPZRTVFX API (see allows a user to specify a particular PTF number and retrieve the information you are interested in using the PTFR0100 Format. The field at offset 40 is the Loaded status.

    I use the API QPZRTVFX and format PTFR0100 to get information about a single PTF.
