KCLUE$SDA_VAX, Utilities, CLUE (Crash Log Utility Extractor) for OpenVMS VAX@ CLUE (Crash Log Utility Extractor) is an addendum to the@ OpenVMS System Dump Analyzer (SDA) utility. It adds some? useful commands to SDA and provides additional displays@ about data structures, either from a system dump file or> from the running system. In addition, it allows you to7 collect and archive information from dumpfiles.? On OpenVMS Alpha, CLUE is implemented as SDA extension.? It is invoked at the SDA> prompt with the CLUE command.@ It runs entirely under control of SDA and uses SDA call-= backs to access, format and display information about> various data structures. You can type CLUE HELP at the> SDA> prompt to obtain further information. The name of< the extension image is SYS$SHARE:CLUE$SDA.EXE; it isA invoked at run-time by SDA with the LIB$FIND_IMAGE_SYMBOL routine.@ On OpenVMS VAX, CLUE is implemented as external utility,B invoked from DCL with the MCR CLUE command. Like on Alpha,; the utility is able to collect and archive dumpfile= information. However, since it does not run under SDA= control, it cannot invoke SDA callbacks and therefore= does not support the displays provided by Alpha CLUE.4 The image is located in SYS$SYSTEM:CLUE.EXE.= This kit contains CLUE$SDA (as SDA extension) on VAX.> It is invoked in the same way as on Alpha and provides? the same or slightly modified commands and displays. It= provides, however, no commands to collect and archiveA information from dumpfiles; these tasks are still covered3 by the external, DEC-supplied CLUE utility.? Like on Alpha, the image name is CLUE$SDA.EXE. The userA may choose to install this image system-wide on SYS$SHARE= (requires privileges) or in a private, user-specified directory.
