similar to: Where & Why is my process sleeping a lot?

We''re running a Solaris 10 container, with an Oracle 9.2.0.4 database - every 5-10 min, an Oracle process shoots up (using 20% + CPU) and then goes down in CPU %, doing a [i]pollsys [/i](see it via dtruss). I tried using some of the trace scripts in the Dtracetoolkit to see what the process is doing, but without any luck - also tried with the following, but dtrace process goes up to 30%

Hi, I have mentioned before that we have added some sdt dtrace probes in SAX, our APL interpreter. Encouraged by Angelo and Jignesh, I have created a small document (5 pages) describing our experience with it, together with some problems we have encountered and some scripts we use for pretty-printing dtrace outputs. The said document can be found at

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

SunOS pop01.unix 5.10 Generic_118844-26 i86pc i386 i86pc dovecot-1.0.beta3 Dovecot itself runs well, and was easy to confirgure with LDAP. However, I am seeing a cpu busy-loop in dovecot-auth. Is this a known issue, or do you know why it happens? If needed I can go deeper if so required. PID USERNAME LWP PRI NICE SIZE RES STATE TIME CPU COMMAND 26440 root 1 10 0 4232K

How can I tell if this is normal behaviour? Oracle imports are horribly slow, an order of magnitude slower than on the same hardware with a slower disk array and Solaris 9. What I can look for to see where the problem lies? The server is 99% idle right now, with one database running. Each sample is about 5 seconds. I''ve tried setting kernel parameters despite the docs saying that

I''m just wondering if anyone has tried this, and what the performance has been like. Scenario: I''ve got a bunch of v20z machines, with 2 disks. One has the OS on it, and the other is free. As these are disposable client machines, I''m not going to mirror the OS disk. I have a disk server with a striped mirror zpool, carved into a bunch of zvols, each exported via

Howdy, Is there a method to get the number of elements in an aggregation? Are the results stored in an aggregation guaranteed to be in any type of order? Thanks for any insight, - Ryan -- UNIX Administrator http://daemons.net/~matty

Hello. I hope someone out there can help with this. It is getting pretty urgent. I am running a Solaris 10 server on Opteron (amd64) hardware and have compiled Dovecot 1.0beta8 from source. It has openssl compiled in (after much mucking around with various environment variables and modifying the Makefile), and was built with: $ ./configure --with-ldap --with-ssl-dir=/etc/ssl $ make # make

Hi there, I am trying to diagnose a performance problem on a Sun T5120 running Solaris 10. I see general poor performance using Java and, in particular, loading classes. I have developed a simple java test that loads all of the classes in a Crystal Reports JAR file (around 7000 classes) which takes much longer on the T5120 (40 secs) than on a Core 2 Duo windows PC (5 secs). I recognise that this

Hi, I am getting "rsync warning: some files vanished before they could be transferred (code 24) at main.c(1039) [sender=3.0.6]" now frequently but while using rsync version 2.6, I used to get it rarely. Any idea would be helpful on why rsync 3.0.6 is throwing this warning frequently. Jignesh. -------------- next part -------------- HTML attachment scrubbed and removed

Hi, I can''t seem to get libvirtd to accept remote connections. Both systems are built using genunix''s b130. It seems that connections originating from the xvm0 server itself are fine but as soon as I go on to the other box and run the same python script (or simply virsh) the connection gets dropped immediately. Telnetting to port 16509 confirms that it drops the connection

Hi, I am not sure how rsync calculates below statistics and how transfer rate 170583.48 bytes/sec ? Where is the total transfer time information? How speedup is 1? How Total bytes written is 6567384? Could someone please give me brief information on this. Number of files: 4 Number of files transferred: 3 Total file size: 6566219 bytes Total transferred file size: 6566219 bytes Literal data:

Hello Friends, Could any one please tell me what is transfer mode and what are the transfer modes available in rsync? Thanks, Jignesh -------------- next part -------------- HTML attachment scrubbed and removed

Hi, I am using below command. rsync --verbose --log-file-format='%i %f %l %o %b' --log-file='/tmp/myfile' src/ dest/ Though it is good that all the sync information contents will be redirected to /tmp/myfile, it would be useful if rsync could print at least below final statistics on stdout. 2009/05/05 00:17:45 [26050] Number of files: 18 2009/05/05 00:17:45 [26050] Number of

Hi Friends, I have started learning rsync source code but I am finding very difficult to go back and forth to find the execution flow. I could see that rsync code is written in UNIX and the compilation is difficult. Does anybody converted it into Windows Project so that we can open in using Visual Studio IDE and it will be very simple to search for some function and find the complete work flow.

Hi, Could anyone please tell me how to get the meaning of rsync error codes. In "rsync return code: 12" error, what 12 indicates? Thanks, Jignesh -------------- next part -------------- HTML attachment scrubbed and removed

Hi, I read below lines in rsync v3.0.5 for --relative option. if you used this command: rsync -av /foo/bar/baz.c remote:/tmp/ ... this would create a file named baz.c in /tmp/ on the remote machine. If instead you used rsync -avR /foo/bar/baz.c remote:/tmp/ then a file named /tmp/foo/bar/baz.c would be created on the remote machine, preserving its full path It is also possible to limit the

As noted on my blog and at http://www.opensolaris.org/os/community/dtrace/shells/ I''ve made available a DTrace provider for the Bourne shell. Before anyone starts yelling at me for not starting with another shell, read the blog I made explaining why we started with shell (link on the community page referenced above). For /bin/sh, I''ve put up something akin to a chapter in

Can zfs send utilize multiple-streams of data transmission (or some sort of multipleness)? Interesting read for background http://people.planetpostgresql.org/xzilla/index.php?/archives/338-guid.html Note: zfs send takes 3 days for 1TB to another system Regards, Jignesh

Hi Friends, Does rsync V3 has the feature for logging the files which have not been transferred? Its already logs the file which have been transfered. Thanks, Jignesh -------------- next part -------------- HTML attachment scrubbed and removed
