The command kdb can be used to analyze a running (!) system, so no processes will be stopped. I am not an expert of the command kdb, but I used it several times and it did not cause any issues. (To be on the safe side try on a test system first :)) I have never used the KDB, Kernel Debugger tool. As far as I know for that a special bosboot and reboot is needed and then you have to work from a terminal console.<br />Here are 2 links how to invoke both of them:<br />kdb: http://publib.boulder.ibm.com/infocenter/pseries/v5r3/index.jsp?topic=/com.ibm.aix.kdb/doc/kdb/kdbcommandinvoke.htm<br />KDB: http://publib.boulder.ibm.com/infocenter/pseries/v5r3/index.jsp?topic=/com.ibm.aix.kdb/doc/kdb/kdbdebuggerinvoke.htmaixhttps://www.blogger.com/profile/11198511213080760662noreply@blogger.comtag:blogger.com,1999:blog-5391325129965939458.post-41743791086988023432013-06-02T10:05:38.939+02:002013-06-02T10:05:38.939+02:00Hi, great article!, however my question is if kdb ...Hi, great article!, however my question is if kdb acts like KDB - meaning if kdb could freeze all processes:<br /><br />"When the KDB kernel debugger is invoked by a condition, it is the only running program.
