  • J2EE Applications, SPARC T4, Solaris Containers, and Resource Pools

    - by user12620111
    I've obtained a substantial performance improvement on a SPARC T4-2 Server running a J2EE Application Server Cluster by deploying the cluster members into Oracle Solaris Containers and binding those containers to cores of the SPARC T4 Processor. This is not a surprising result, in fact, it is consistent with other results that are available on the Internet. See the "references", below, for some examples. Nonetheless, here is a summary of my configuration and results. (1.0) Before deploying a J2EE Application Server Cluster into a virtualized environment, many decisions need to be made. I'm not claiming that all of the decisions that I have a made will work well for every environment. In fact, I'm not even claiming that all of the decisions are the best possible for my environment. I'm only claiming that of the small sample of configurations that I've tested, this is the one that is working best for me. Here are some of the decisions that needed to be made: (1.1) Which virtualization option? There are several virtualization options and isolation levels that are available. Options include: Hard partitions:  Dynamic Domains on Sun SPARC Enterprise M-Series Servers Hypervisor based virtualization such as Oracle VM Server for SPARC (LDOMs) on SPARC T-Series Servers OS Virtualization using Oracle Solaris Containers Resource management tools in the Oracle Solaris OS to control the amount of resources an application receives, such as CPU cycles, physical memory, and network bandwidth. Oracle Solaris Containers provide the right level of isolation and flexibility for my environment. To borrow some words from my friends in marketing, "The SPARC T4 processor leverages the unique, no-cost virtualization capabilities of Oracle Solaris Zones"  (1.2) How to associate Oracle Solaris Containers with resources? There are several options available to associate containers with resources, including (a) resource pool association (b) dedicated-cpu resources and (c) capped-cpu resources. I chose to create resource pools and associate them with the containers because I wanted explicit control over the cores and virtual processors.  (1.3) Cluster Topology? Is it best to deploy (a) multiple application servers on one node, (b) one application server on multiple nodes, or (c) multiple application servers on multiple nodes? After a few quick tests, it appears that one application server per Oracle Solaris Container is a good solution. (1.4) Number of cluster members to deploy? I chose to deploy four big 64-bit application servers. I would like go back a test many 32-bit application servers, but that is left for another day. (2.0) Configuration tested. (2.1) I was using a SPARC T4-2 Server which has 2 CPU and 128 virtual processors. To understand the physical layout of the hardware on Solaris 10, I used the OpenSolaris psrinfo perl script available at http://hub.opensolaris.org/bin/download/Community+Group+performance/files/psrinfo.pl: test# ./psrinfo.pl -pv The physical processor has 8 cores and 64 virtual processors (0-63) The core has 8 virtual processors (0-7)   The core has 8 virtual processors (8-15)   The core has 8 virtual processors (16-23)   The core has 8 virtual processors (24-31)   The core has 8 virtual processors (32-39)   The core has 8 virtual processors (40-47)   The core has 8 virtual processors (48-55)   The core has 8 virtual processors (56-63)     SPARC-T4 (chipid 0, clock 2848 MHz) The physical processor has 8 cores and 64 virtual processors (64-127)   The core has 8 virtual processors (64-71)   The core has 8 virtual processors (72-79)   The core has 8 virtual processors (80-87)   The core has 8 virtual processors (88-95)   The core has 8 virtual processors (96-103)   The core has 8 virtual processors (104-111)   The core has 8 virtual processors (112-119)   The core has 8 virtual processors (120-127)     SPARC-T4 (chipid 1, clock 2848 MHz) (2.2) The "before" test: without processor binding. I started with a 4-member cluster deployed into 4 Oracle Solaris Containers. Each container used a unique gigabit Ethernet port for HTTP traffic. The containers shared a 10 gigabit Ethernet port for JDBC traffic. (2.3) The "after" test: with processor binding. I ran one application server in the Global Zone and another application server in each of the three non-global zones (NGZ):  (3.0) Configuration steps. The following steps need to be repeated for all three Oracle Solaris Containers. (3.1) Stop AppServers from the BUI. (3.2) Stop the NGZ. test# ssh test-z2 init 5 (3.3) Enable resource pools: test# svcadm enable pools (3.4) Create the resource pool: test# poolcfg -dc 'create pool pool-test-z2' (3.5) Create the processor set: test# poolcfg -dc 'create pset pset-test-z2' (3.6) Specify the maximum number of CPU's that may be addd to the processor set: test# poolcfg -dc 'modify pset pset-test-z2 (uint pset.max=32)' (3.7) bash syntax to add Virtual CPUs to the processor set: test# (( i = 64 )); while (( i < 96 )); do poolcfg -dc "transfer to pset pset-test-z2 (cpu $i)"; (( i = i + 1 )) ; done (3.8) Associate the resource pool with the processor set: test# poolcfg -dc 'associate pool pool-test-z2 (pset pset-test-z2)' (3.9) Tell the zone to use the resource pool that has been created: test# zonecfg -z test-z1 set pool=pool-test-z2 (3.10) Boot the Oracle Solaris Container test# zoneadm -z test-z2 boot (3.11) Save the configuration to /etc/pooladm.conf test# pooladm -s (4.0) Results. Using the resource pools improves both throughput and response time: (5.0) References: System Administration Guide: Oracle Solaris Containers-Resource Management and Oracle Solaris Zones Capitalizing on large numbers of processors with WebSphere Portal on Solaris WebSphere Application Server and T5440 (Dileep Kumar's Weblog)  http://www.brendangregg.com/zones.html Reuters Market Data System, RMDS 6 Multiple Instances (Consolidated), Performance Test Results in Solaris, Containers/Zones Environment on Sun Blade X6270 by Amjad Khan, 2009.

  • Oracle 12c: First (and best!) on Solaris

    - by mgerdts
    Oracle 12c is now available for download.  Notice that support for Solaris SPARC and x86-64 are among the operating systems supported on the first day of availability. New database features that relate to Solaris include: I/O outlier support.  This is made possible through the database's use of DTrace, and as such Solaris has a clear edge here. Oracle ACFS Replication and Tagging for Solaris Integration with Solaris resource pools As has been the case for some time, Oracle databases are supported in zones.

  • Solaris TCP stack tuning

    - by disserman
    We have a large web project (about 2-3k requests per second), using haproxy (http://haproxy.1wt.eu/) as a frontend and load balancer between the java application servers. The frontend (haproxy) is running on Linux but we are going to migrate it to the Solaris 10 as all our other servers are running under Solaris. After switching a traffic I see the two things: a) the web site became loading slower (5-10 seconds with images in comparison to 2-3 seconds on Linux) b) sometimes haproxy fails to perform a "lifecheck" (get a special web page and analyze http response code) due to the socket timeout. After switching traffic back to Linux everything is okay. I've tried to tune all params I found in /dev/tcp but no progress. I believe the problem is in some open socket limitations. If someone can point me to the answer, I would be greatly appreciated. p.s. haproxy is running under Xen DomU on Linux (Kernel 2.6.18, Debian 5), under zone on Solaris (10 u8). the only thing we did on Linux is increasing of ip_conntrack_max (I believe Solaris option tcp_conn_req_max_q is the equivalent).

  • Why doesn't my environment variable get set?

    - by reprogrammer
    I have to set an environment variable called GDK_NATIVE_WINDOWS to fix the problem with Eclipse buttons in Ubuntu. To set the environment variable, I added the following line to ~/.pam_environment. GDK_NATIVE_WINDOWS DEFAULT=true Surprisingly, the environment variable doesn't get set when I echo $GDK_NATIVE_WINDOWS in a terminal. However, all other environment variables that I've listed in ~/.pam_environment are set properly. Besides, when I switch to a tty, e.g. Alt+Ctrl+F1, the environment variable gets set correctly. Can anyone tell what's wrong with setting this environment variable in ~/.pam_environment?

  • Operating system not found after downloading skin pack

    - by 8BitSensei
    My brother has downloaded a executable file from Skin Pack — I believe it was the Mountain Lion IO6 skin pack. He's using an Acer Aspire 553G. And now his operating system won't start (Windows 7). It gets to the BIOS and then goes to load up the OS but the screen goes blank and it just goes back to the BIOS over and over again. He decided to play with the bootup settings and tried different options and got the error message "Operating System not found." Does anyone have any idea how to solve this?

  • Problem in installing OpenOffice 3.1 on Solaris 10

    - by Sunil Kumar Sahoo
    I want OpenOffice in Solaris. So I downloaded OpenOffice from the link below. http://download.openoffice.org/other.html#tested-full My OpenOffice is in .tar.gz format so I unzipped the file using gunzip and then untar'ed the file using tar xvf command. Now I got a directory containing packages subfolder. When I cd to that directory I found too many subdirectories. I could not find a single .pkg file or .jar file or .sh file so that I can install the OpenOffice in Solaris 10. How can I install OpenOffice in Solaris 10 given the scenario above?

  • Solaris 32bit / 64bit confusion

    - by goldenmean
    I have a Solaris on a AMD- uname -a gives OS Solaris 10 x86_64 (SunOS goldtpus34 5.10 Generic_144489-11 I wanted to find whether it has a 32bit or 64 bit kernel so I did /usr/bin/isainfo -k it says amd64 but when i do file /sbin/init it says ELF 32-bit LSB executable 80386 Version 1, dynamically linked, stripped Also if I do file it says ELF 64-bit LSB executable AMD64 Version 1 [SSE2 SSE FXSR FPU], dynamically linked, not stripped So is it possible to have a Kernel working in 64bit mode but System utils/process spawner(init) in 32bit mode. I am confused. How to accurately get if the OS Kernel is in 64/32 bit mode on Solaris and on Linux?

  • Issues running java in Solaris 9 container

    - by Matthew Watson
    Hi, I have a solaris 9 container built from a physical server using flarcreate. Everything seems fine, except when trying to trying to run any "java -server" process it fails with the following error This is on a Sunfire T1000 machine running Solaris 10 10/09 s10s_u8wos_08a SPARC Running jdk1.5.0_15 Exception java.lang.OutOfMemoryError: requested -4 bytes for size_t in /BUILD_AREA/jdk1.5.0_15/hotspot/src/os/solaris/vm/os_solaris.cpp. Out of swap space? As far as I can tell I'm not actually out of swap space. Running java in client mode works without a problem. Googles only suggestion is related to x86. Any suggestions? Thanks.

  • TCP failure on Solaris

    - by anurag kohli
    Hi All, I recently ran into a problem where a Solaris server could not establish a TCP socket on port 2126. From a packet capture I see this (note: A is a Solaris server, B is a router): A sends SYN to B B sends SYN, ACK to A Notice A (Solaris) does not acknowledge the SYN from B. Due to the business impact of the problem, I had to reboot the server to fix the problem. That said, I want to know the next time the problem occurs, what can I do to get a root cause (ie before server reboot)? Thanks in advance.

  • Problems with vim/locale as non-root user on Solaris

    - by Lyle
    I do some work on a Solaris 10 machine, and my .vimrc is set up to show unicode characters for tabs and line endings: set listchars=tab:?\ ,eol:¬ This works out of the box on my OS X machine. On Linux as well as Solaris I get the following error when I start vim: Error detected while processing /home/lhanson/.vimrc: line 17: E474: Invalid argument: listchars=tab:?~V?\ ,eol:¬ I solved this on my Linux box by setting LANG=en_US.utf8 ('locale -a' shows this as being an option). On Solaris, however, 'locale -a' shows the following: C POSIX iso_8859_1 Setting LANG to C or POSIX yields the same error, and even though iso_8859_1 probably wouldn't work it doesn't successfully change the locale anyway. As a non-root user, is there any way I can have my unicode characters show up?

  • How to burn a CD-ROM from a Mac for Solaris

    - by cope360
    I would like to burn a CD using a Mac (10.5) which I can then access from a Solaris 10 x86 machine. This partially works: Insert blank CD and let the Finder open it so it creates a "Recordable CD" window for it. Drag the files to be burned into the "Recordable CD" window Burn (there are no options except for speed) Then to mount in Solaris: mount -f hsfs -o ro /dev/dsk/foo /mnt/bar The problem here is that Solaris will see all the filenames as lower case and it will only allow each file name to contain one period (these are HSFS limitations). My guess is that the Mac is not burning the disc with the Rock Ridge extensions that allow for the full file names to be preserved. Is there some combination of burning tools/options and mount options that will make this work?

  • Disk names in Solaris 10 for ZFS: SAS WWN instead of c0t0d0

    - by notpeter
    I currently have a server running Solaris 10u9 with a SAS enclosure (Dell PowerVault MD1000) filled with SATA disks attached to an SAS card (LSI 3801E). It happily recognizes the 15 disks in the MD1000 and presents them each disk in the traditional solaris form (c1t12d0, c1t13d0, c1t15d0, etc). My home ZFS setup (Nexenta CP3 + LSI 9200-16E + directly cabled SATA disks) presents disks as their SAS WWN ID (ex: c3t600039300001EA56d0). Although this ID is longer, I've found it much easier to troubleshoot because the cabling/slot is irrelevant, ZFS just identifies the disk by ID, if it's connected it finds it. Most manufacturers print the WWN right on the disk's top label, can't get much easier than that. So how can I get Solaris to identify disks by SAS WWN instead of by the cXtXdX?

  • How to configure HA iSCSI for Solaris 10

    - by Noah
    BACKGROUND: We have a StarWind NAS that we are currently using for High Availability storage with our Windows network. Starwind has mirrored drives and multiple ip paths, that the Windows Server combines into one HA disk store. QUESTION: How do I accomplish the same thing under Solaris 10? I've looked at ZFS but to document seems to indicate that ZFS wants to do its own raid/mirroring. I can also attach via iSCSI from Solaris and am presented with both drives being served by the Starwind NS. So, how do I configure solaris so that disk M1 and M2 are considered as a single fault tolerant drive?

  • solaris + EMC + power-path

    - by yael
    please advice - when I run powercf command on my Solaris machine , which changes this command do on the EMC storage , or on Solaris file system ? from maanual page: DESCRIPTION During system boot on Solaris hosts, the powercf utility configures PowerPath devices by scanning the HBAs for both single-ported and multiported storage system logical dev- ices. (A multiported logical device shows up on two or more HBAs with the same storage system subsystem/device identity. The identity comes from the serial number for the logical device.) For each storage system logical device found in the scan of the HBAs, powercf creates a corresponding emcpower device entry in the emcp.conf file, and it saves a primary path and an alternate primary path to that device.

  • How to deal with a 'public' work environment?

    - by Craige
    In the last 6 months, I have changed desks at my office 4 times. I don't mind, as it's due to expansion of the company and acquiring new office space and getting everybody settled. However, I truly miss the semi-private office I sat in 2 desks ago. I am now sitting in a large room with a number of other people. My problem with this isn't with my co-workers; everybody here is great. My problem is that based on the configuration of the room, no matter which desk I sit in, my monitors WILL be facing an open window. This causes a glare on my monitors, and it drives me crazy. I prefer a dark IDE theme as I find it easier on the eyes, however this just makes the glare that much worse. How should programmers cope with public office settings? Secondly, how should I cope with my specific problem? Should I give in and adopt a light IDE theme that will reduce the visibility of the glare but increase eye strain, or should I stick to my guns and find another solution?

  • How can I create a solid business case for upgrading our programmers to 256 GB SSD and 16 GB of RAM?

    - by Alex. S.
    We have an environment based on Microsoft stack (VS2010, SQL Server, etc), and I firmly believe that we could improve productivity a little bit, having more RAM and a faster secondary SSD. What data do you advice to gather so I can solidify my request in such a way the advantages can be unbiasedly demonstrated? Currently we have only 6GB of RAM and slower HD drives, and at home I have a 128 GB SSD in my desktop and 16 GB of RAM (I also think is the max amount of memory supported by our workstations, if we could go bigger then better), so I can feel the difference and it's real. I also want to add that we are in an industry with plenty of money, so the issue actually is how to get a budget approval from management and spend it wisely to increase productivity.

  • Working on a virtual machine as a developer

    - by Johnny000
    In the company I'm currently working in, they decided that each developer will move to a VM desktop (Citrix/WinServer2012) an develop/test from there with restricted/no rights to install new software. The Server we will be working on are in a remote Datacenter. So i.e. if for some reason or another the internet brake down, we can't work till the connection is up again. As a developer I don't want to use windows as OS for my working/development environment as there is no need because we don't develop OS specific software. What good points could I raise in an argumentation against moving to the VMs beside the loss/restriction of freedom and the loss of connection to the internet?

  • script engine with no global environment (java)

    - by user1886930
    I am curious about how global variables are handled by script engines. I am looking for a script engine that does not preserve the state of global variables upon invocation. Are there such engines out there? We are looking for a scripting language we can use under the script engine API for Java. When making multiple invocations of a script engine, top-level calls to eval() or evaluate() method preserves the state of global variables, meaning that consequent calls to eval() will use the global variables as they were left by the last invocation. Is there a script engine that does not preserve the state, or provides the ability to reset the state, so that global variables are at their initial state every time the script engine is invoked?

  • How to persistently export an environment variable before starting compiz

    - by Dykam
    A few months ago compiz suddenly stopped working. That is, it got to a refreshrate where the redrawing is more than noticeable. It took 5 seconds to redraw a chat window. Ever since I've been using metacity instead, but I've found myself missing some plugins badly. I found the following solution: export __GL_YIELD="NOTHING"; compiz --replace This works fine, everything is fast again with compiz. But how to make sure this variable is always set whenever I run compiz? I'm using standard nVidia drivers, failed to get the open source ones working.

  • Working environment

    - by Yottatron
    I realise that this might not be the right place to ask questions about employment and that the question my raise debate etc. The company I work for recently decided that rather than having one web developer working on sites from a branch it would be better to make that person come into head office and work in the middle of a busy call centre. Also they're expecting the developer to answer the phone if it rings and take messages. Does anyone find that strange? Is it really the right place for a programmer to work? Thanks for the advice

  • Are there similarities between operating system kernels and programming language kernels?

    - by rahmu
    I know very little about Smalltalk but I noticed that there's a frequent mention of the "kernel". Dan Ingalls prime maintainer of several implementations of Smalltalk also worked on a Javascript environment called "Lively Kernel" and in Peter Siebel's book he kept mentionning the "kernel". I cannot help but think that it is no coincidence that the creators of Smalltalk used the name of a (central) part of operating systems to refer to a particular component of their language. Was it because Smalltalk intended to act as an operating system? Was it because theory behind programming languages and operating systems have a lot in common? What is the reason behind the common appelation of the two components?
