5042.0. "RDB and DEC PCA" by 140.87.65.1::BZINN ([email protected]) Tue Feb 18 1997 14:17

    Anybody out there worked with PCA and RDB?
    
    RDB 6.1-04 MV
    
    I have a customer who is trying to use PCA to check the performance of
    his program. To do this, he apparently compiles and links with DEBUG.
    
    If he then runs the resulting .EXE, no problem.
    If he defines a logical LIB$DEBUG to whatever enables the PCA collector
    to do its thing, the same .EXE fails with an RDB-E-UNAVAILABLE 
    
    I believe its because some part of PCA is not picking up the logicals
    pointing at all the MV images and such. He says that the logicals are
    all set for his process, and that's the one that's reporting the error,
    that if PCA was having a problem, the collector would fail or report an
    error.
    
    Does anyone know enough about PCA to tell where the ball is being
    dropped?

	Perhaps some images need to be installed?

	Well, all the 'normal' ones are installed. The only difference between running and failing is the DCL line $define lib$debug sys$share:pca$collector Having them analyze pca$collector to see if it pulls in anything unusual. Will also try with SET WATCH to see if we can tell where its failing.

	are the PCA image(s) installed similarly to DEBUG*.EXE?
5042.4		NOVA::DICKSON		`Tue Feb 18 1997 16:01`	2
	Doesn't PCA run the program under test in a sub-process? Does that sub-process get its RDB environment set up?

	PCA run's in the process's context. Basically, when you use PCA, it runs like the debugger would. You tell PCA to collect information about whatever you want (I/Os, CPU time, PC sampling, whatever) and it records the information into a data file. Later on, you analyze the data file.

	They still can't get this thing to run. MV 6.1 is defined as the system default version. Without PCA, everything runs fine. Tried installing SQL$SHR61 and SQL$INT, just in case. They're going to try to talk to a PCA specialist at Digital.
