C R A S H D U M P A N A L Y S E R In the event of a crash a crash message will appear on TT0: requesting that a scratch medium (e.g. tape) be mounted for taking a CRASH DUMP of the system. After it is mounted the CONTINUE switch is pressed and the system dumped to the medium. (If your system does not have a switch register boot in the console emulator, load the PC given and type S.) The Utility CDA may then be used after rebooting the system, to analyze the cause of the system crash. For further HELP with CDA type HELP CDA keyword where keyword is one of the following. COMMANDLINE The CDA commandline and its use. SWITCHES REPORT CDA report selection switches. SWITCHES FUNCTION CDA function control switches 2 COMMANDLINE Assuming the system was dumped to magtape, the command line is [listfile/sw],[binary file/sw]=symbol file/STB,crash-input[/sw] listfile A readable crash report sent either to TI: or a disk file. binaryfile An optional binary file. A magtape dump can be transfered to disk for faster access. symbolfile [1,54]RSX11M.STB crash input Either MT:, or a disk file specifier. 2 SWITCHES CDA supports two groups of switches, report selection switches and function control switches. type HELP CDA SWITCHES REPORT or HELP CDA SWITCHES FUNCTION 3 REPORT The CDA report control switches should be placed on the crash-input specifier. /ACT List Task Control Blocks for each active task. /ALL List output of all analysis routines. /CLQ List the contents of the clock queue. /DECNET List contents of DECNET data structures. /DEV Lists information on all devices in the system. /DUMP:a:b Dumps memory contents between addresses a and b. /HDR Lists the contents of the task headers for each task resident in memory. /NET Same as /DECNET. /PCB Lists the contents of each Partition Control Block. /POOL Lists the contents of the system POOL. /TASK=name:a:b Lists the contents of task 'name' between virtual addresses a and b. /STD Lists the contents of the System Task Directory for all tasks. /-SYS Suppress listing of first 6/7 pages of System Information. 3 FUNCTION /BL:n apply to crash-input. Identifies the starting block number of the crash input device. Default=1. /EXIT:n apply to list file. Terminate analysis after encountering n analysis errors. /LIMIT:n apply to list file. Terminate listing after n pages. /MEMSIZ:n Apply to binary file. Create a binary output file 4*n blocks long. /KMR Apply to crash input file. Force assignment of page address registers. /-SP Apply to list file. Do not SPOOL output. /STB The file is the executive symbol table file.
