I am generating the coredump of my JBoss, and by default it puts it in to a particular directory. i.e. JBOSS_HOME/. I would like this output file to be created, lets say in /tmp/dump/.

I tried the following:

Code:
kill -3 9404940>/tmp/dump/out.txt
But it created /tmp/dump/out.txt with 0 KB, and yet it created the dump file in JBOSS_HOME/ directory.

Can you please let me know how can I have kill -3 to create the core dump file in the desired location?

i am facing some weired issues.
case is like this :-
initially i was on AIX 5.3
i have installed filesets related to my application and those were in APPLY state.(COMMIT is set as NO)
Then i have taken lslpp -l| grep -i <apps name>
in that i confirmed whether the filesets are in APPLIED state or not. They were in APPLIED state. I have created some data.
Now i upgraded the system (5.3) to aix 6.1 and after upgradation i checked the lslpp o/p the it was showing the same filesets (which were in APPLIED state in 5.3) in COMMITED state.

Because of this i am not able to add new filesets even though using "OVERWRITE option which is set as YES."

Any pointers why this is happening ?
ideally the filesets should be in APPLIED state. ]]> AIX harsh_mulay http://www.unix.com/aix/124122-upgrade-aix-5-3-6-1-a.html lvm http://www.unix.com/aix/124119-lvm-new-post.html Thu, 19 Nov 2009 07:57:42 GMT Hi. can anyone define about VGDA,VGSA,and quorum in aix.. Hi.

In other words when a process gets a new memory page, this one must be cleaned.

I've solved this issue for Solaris using DTrace.
I found out that in Solaris memory pages are cleaned by pagezero routine.
So using entry and return probes of fbt provider in DTrace and getting input and output of the functions which are used in pagezero implementation I achieved my goal.

And now I have to solve the same task in AIX.
As I understand the source code of AIX is closed and that way which was used in Solaris isn't fit.

First of all could you tell me how can I translate the virtual address which was gotten from malloc to the physical address?

I thought it's possible to do using kdb and its tr command.
But when I type the next command in kdb:
(0)> tr 0x20001878
i get the next result:
WARNING: 0000000020001878 invalid sid
where 0x20001878 is the address which was gotten from malloc, and sid - segment identifier.
May be it's because the main purpose of kdb is debugging of kernel extension and my actions are wrong?
