similar to: What is <DYN> in dtrace source code?

Hi all... I''ve just got my hands on a Solaris 10 box for the first time. I''ve heard wonderous things about dtrace, so the first command I type is dtrace -l which disappointingly does nothing at all. It just hangs, and neither Ctrl-D, Ctrl-C or kill -9 from another shell will do anything to kill it. The box is: SunOS t2000 5.10 Generic_118822-25 sun4v sparc SUNW,Sun-Fire-T200

I have a number of systems running solaris10 and i see the package and binary for dtrace installed however whenever we try to run anything we get this error dtrace: failed to initialize dtrace: DTrace device not available on system the only system in which i dont have this error is the development server that has the full solaris 10 install while others are minimized, do i need additional

Hello, I hope that this mailing list is "alive", since I am looking for a solution for my problem for a long time. I would like to migrate my existing dovecot installation from mysql to pgsql. But I have problems with the passwords when using pgsql. The existing and working mysql-based installation looks like this: dovecot-sql.conf.ext: driver = mysql default_pass_scheme =

Hi all, I''m trying to run dtrace -c on a program that takes command-line arguments... is there any way to tell dtrace where its args let off and the target''s begin, or will I have to write a shell script that checks for ''--'' or some such? Thanks, Ryan -- This message posted from opensolaris.org

I''m getting an odd behavior while trying to trace a mysql process using the -p flag on a Sun Cluster. This fails # dtrace -n ''pid$target::*mysql_parse*:entry {}'' -p `pgrep -x mysqld` dtrace: failed to grab pid 16537: process is traced Yet this works # dtrace -n ''pid$1::*mysql_parse*:entry {}'' `pgrep -x mysqld` dtrace: description

Greetings, is there a way to specify probes and other dtrace operations via command line parameters, like " BEGIN { usr_exec=$$1; usr_syscall=$$2; } syscall::usr_syscall:entry /execname == usr_exec && guard++ == 0/ { ... " [this does not work] This would make it possible to create "generic" dtrace scripts. Otherwise, some shellscript with sed-magic would

I''d like to prepend TRACE_ to the macro names generated by dtrace -h. For example, change POSTGRESQL_LWLOCK_ACQUIRE(arg0, arg1) to TRACE_POSTGRESQL_LWLOCK_ACQUIRE(arg0, arg1) and still keep postgresql as the provider name. The reason for doing this is to make it clear that the macros are used for (D)tracing. In this particular case, without TRACE_, it appears like the macro is used

DTrace folks, I''m pleased to introduce a potential new DTrace-sponsored project: the Erlang DTrace provider. To be good OpenSolaris citizens, we want to put the formation of this officially sponsored project to a vote -- as outlined in the OpenSolaris Constitution -- so here are the details for the new Project, as prepared by the Project Team: Name : Erlang DTrace Integration

Hi all, I know Chi-squared test can be done with the frequency data by R function "chisq.test()", but I am not sure if it can be applied to the percentage data ? The example of my data is as follow: ############################################# KSL MHL MWS CLGC LYGC independent (%) 96.22 92.18 68.54 93.80 85.74

Hi, i have many variables for in example 4weeks and want to do aggregations, like mean standard , deviation etc.. With mean it works but how i can calculate the standard deviation for the 4weeks and for every ID. many thanks & regards, christian week1 <- grep("(_PRO_001)",names(dmx3),perl=T) week1table <- subset(dmx3,select=c(ID,week1)) week2 <-

Howdy, I am trying to migrate several scripts to use application defined types, and am running into a few issues. When I attempt to run a script with a application defined type, it looks like the DTrace preprocessor is getting angry with me: $ cat view.d #include "httpd.h" :::acceptconnection { this->addr = (conn_rec *)copyin(arg0,sizeof(conn_rec *)); } $ dtrace -C

Hey, Do you guys think that is a good idea to have a manual page for each provider with a complete description of what probes are offered ? Found some already under 7D category: dtrace dtrace (7d) - DTrace dynamic tracing facility fasttrap fasttrap (7d) - DTrace user instruction tracing provider fbt fbt (7d) - DTrace function boundary tracing provider

There is a Slashdot discussion today titled "Cambridge Researcher Breaks OpenBSD Systrace". Slashdot anonymous member has a comment "Even Sun''s Dtrace might be vulnerable." I don''t think it is.

i''m running the following script: #pragma D option quiet profile:::tick-1sec / ++x >= 15 / { exit(0); } io:::start { @io_size[execname] = sum(args[0]->b_bcount); } on exit, the script prints out the value of @io_size, why? there''s no printa(), and i also specified "D option quiet" (i also tried -q). this seems to happen with any kind of probe: on exit(0) all

Hello zfs-discuss, Is someone actually working on it? Or any other algorithms? Any dates? -- Best regards, Robert mailto:rmilkowski at task.gda.pl http://milek.blogspot.com

Just to let people know what my big picture is, I''m trying to write a script that will let me run a program, and name a progeny of that program that I want to debug. My script should find the first occurrence of that progeny, and run it until it finishes initializing the runtime linker, but stop it before it runs any shared library startup routines. (Failing that, I''d be okay

I have some C code I would like to call from R (involves passing a 2D double array with a few other variables, processing it and returning it to R). I have the Win95 version of R and the dyn.load example builds ok. I need more info on writing the R and C interface. What is a good source of reference for this ? -- Douglas Steele
