  • Weblogic is slow to start (11mins) under VM (VirtualBox and VMware)

    - by Vladimir Dyuzhev
    (SOLVED! BY FAKING SYSTEM RANDOM GENERATOR, SEE BELOW) I'm setting up a VM image for my dev/build team. Inside that VM a Weblogic domain should be running. I use Ububtu server distro, WLS 9.2MP3 + ALSB. Everything works OK, quite fast, but at the start time the WLS stops twice for a measurable amounts of time. Two stops in total amount to about 10 minutes delay. For tasks where deployment requires server restart it's very annoying. :-( Sleeping time is not constant, sometimes the server starts very fast, sometimes so-so, sometimes 10 minutes or more. Interesting that if I press Enter while looking at the stopped server, it wakes up much faster, sometimes after a few seconds. WLST (Weblogic Jython shell) is also hanging for quite a time when executed in VM. It doesn't react to Enter though. Here must be some developers who run WLS with a VM. I wonder if others have the same problem? Was someone able to solve it? Here's the server output (just for a case): Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_12-b04) Java HotSpot(TM) Client VM (build 1.5.0_12-b04, mixed mode) Starting WLS with line: /shared2/beahome/jdk150_12/bin/java -client -Xmx256m -XX:MaxPermSize=128m -Xverify:none -da -Dplatform.home=/shared2/beahome/weblogic92 -Dwls.home=/shared2/beahome/weblogic92/server -Dwli.home=/shared2/beahome/weblogic92/integration -Dweblogic.management.discover=true -Dwl w.iterativeDev= -Dwlw.testConsole= -Dwlw.logErrorsToConsole= -Dweblogic.ext.dirs=/shared2/beahome/patch_weblogic923/profiles/default/sysext_ manifest_classpath -Dweblogic.management.username=admin -Dweblogic.management.password=wlsadmin -Dweblogic.Name=LOGMGR-admin -Djava.security .policy=/shared2/beahome/weblogic92/server/lib/weblogic.policy weblogic.Server <1-Apr-2010 12:47:22 o'clock PM GMT-05:00> <Notice> <WebLogicServer> <BEA-000395> <Following extensions directory contents added to the end of the classpath: /shared2/beahome/weblogic92/platform/lib/p13n/p13n-schemas.jar:/shared2/beahome/weblogic92/platform/lib/p13n/p13n_common.jar:/shared2/beahom e/weblogic92/platform/lib/p13n/p13n_system.jar:/shared2/beahome/weblogic92/platform/lib/wlp/netuix_common.jar:/shared2/beahome/weblogic92/pl atform/lib/wlp/netuix_schemas.jar:/shared2/beahome/weblogic92/platform/lib/wlp/netuix_system.jar:/shared2/beahome/weblogic92/platform/lib/wl p/wsrp-common.jar> <1-Apr-2010 12:47:22 o'clock PM GMT-05:00> <Info> <WebLogicServer> <BEA-000377> <Starting WebLogic Server with Java HotSpot(TM) Client VM Ve rsion 1.5.0_12-b04 from Sun Microsystems Inc.> <1-Apr-2010 12:47:23 o'clock PM GMT-05:00> <Info> <Management> <BEA-141107> <Version: WebLogic Server 9.2 MP3 Mon Mar 10 08:28:41 EDT 2008 1096261 > <1-Apr-2010 12:47:25 o'clock PM GMT-05:00> <Info> <WebLogicServer> <BEA-000215> <Loaded License : /shared2/beahome/license.bea> <1-Apr-2010 12:47:25 o'clock PM GMT-05:00> <Notice> <WebLogicServer> <BEA-000365> <Server state changed to STARTING> <1-Apr-2010 12:47:25 o'clock PM GMT-05:00> <Info> <WorkManager> <BEA-002900> <Initializing self-tuning thread pool> <1-Apr-2010 12:47:25 o'clock PM GMT-05:00> <Notice> <Log Management> <BEA-170019> <The server log file /shared2/wldomains/beaadmd/LOGMGR/ser vers/LOGMGR-admin/logs/LOGMGR-admin.log is opened.

SecureRandom by default uses /dev/urandom file. For some reason, reading this file under VM comes to halt quite often. Generating console events helps to create more randomness, and release the WLS. For the test purposes I have changed jre/lib/security/java.security file, property to securerandom.source=file:/tmp/big.random.file. Weblogic now starts in 15 seconds.

  • ASP.NET MVC 2 strange behavior

    - by Voice
    Hi Recently I installed VS 2010 Release (migrated from RC) and my MVC application is not working anymore. More concrete: I have a wizard with several steps for new customer account creation (Jquery form wizard, but it doesn't really matter). Each step contains a typed partial View for each part of account: Company, Customer, Licence, etc. When I submit the form I see really strange thing in ModelState. There are duplicate keys for Company: with "Company" prefix and without it. Something like this: [6] "Company.Phone" string [12] "Phone" string My model state for all these keys is not valid because Company is actually null and validation fails. When it was RC there were no such keys with "Company" prefix. So these keys in ModelState with prefix "Company" appeared after I installed VS Release. Here is my code: Main View <div id="registerSteps"> <div id="firstStep" class="step"> <fieldset> <legend><%=Html.Encode(Register.CustomerInfo) %></legend> <% Html.RenderPartial("CustomerInfo", ViewData["newCust"]); %> </fieldset> </div> <div id="secondStep" class="step"> <fieldset> <legend><%=Html.Encode(Register.CompanyInfo) %></legend> <% Html.RenderPartial("CompanyInfo", ViewData["newComp"]); %> </fieldset> </div> <div id="thirdStep" class="step"> <fieldset> <legend><%=Html.Encode(Register.LicenceInfo) %></legend> <% Html.RenderPartial("LicenceInfo", ViewData["newLic"]); %> </fieldset> </div> <div id="lastStep" class="step"> <fieldset> <legend><%=Html.Encode(Register.PrivacyStatement) %></legend> <% Html.RenderPartial("PrivacyStatementInfo"); %> </fieldset> </div> <div id="registerNavigation"> <input class="navigation_button" value="Back" type="reset"/> <input class="navigation_button" value="Next" type="submit"/> </div> </div> Two partial views (to show that they are actually identical): Company: <div id="dCompanyInfo"> <div> <div> <%=Html.LocalizableLabelFor(company => company.Name, Register.CompanyName) %> </div> <div> <%=Html.TextBoxFor(company => company.Name) %> <%=Html.ValidationMessageFor(company => company.Name) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(company => company.Phone, Register.Phone) %> </div> <div> <%=Html.TextBoxFor(company => company.Phone) %> <%=Html.ValidationMessageFor(company => company.Phone) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(company => company.Fax, Register.Fax) %> </div> <div> <%=Html.TextBoxFor(company => company.Fax) %> <%=Html.ValidationMessageFor(company => company.Fax) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(company => company.Size_ID, Register.CompanySize) %> </div> <div> <%=Html.ValueListDropDown(company => company.Size_ID, (CodeRoad.AQua.DomainModel.ValueList)ViewData["CompSize"], (string)ViewData["Culture"]) %> <%=Html.ValidationMessageFor(company => company.Size_ID) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(company => company.Industry_ID, Register.Industry) %> </div> <div> <%=Html.ValueListDropDown(company => company.Industry_ID, (CodeRoad.AQua.DomainModel.ValueList)ViewData["Industry"], (string)ViewData["Culture"]) %> <%=Html.ValidationMessageFor(company => company.Industry_ID) %> </div> </div> </div> And for Customer <div id="dCustomerInfo"> <div> <div> <%=Html.LocalizableLabelFor(customer => customer.Email, Register.Email) %> </div> <div> <%=Html.TextBoxFor(customer => customer.Email) %> <%=Html.ValidationMessageFor(customer => customer.Email) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(customer => customer.Male, Register.Gender) %> </div> <div> <%=Html.ListBoolEditor(customer => customer.Male, Register.Male, Register.Female, Register.GenderOptionLabel) %> <%=Html.ValidationMessageFor(customer => customer.Male) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(customer => customer.FirstName, Register.FirstName) %> </div> <div> <%=Html.TextBoxFor(customer => customer.FirstName) %> <%=Html.ValidationMessageFor(customer => customer.FirstName) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(customer => customer.LastName, Register.LastName) %> </div> <div> <%=Html.TextBoxFor(customer => customer.LastName) %> <%=Html.ValidationMessageFor(customer => customer.LastName) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(customer => customer.Role_ID, Register.Role) %> </div> <div> <%=Html.ValueListDropDown(customer => customer.Role_ID, (CodeRoad.AQua.DomainModel.ValueList)ViewData["OrgRole"], (string)ViewData["Culture"]) %> <%=Html.ValidationMessageFor(customer => customer.Role_ID) %> </div> </div> </div> There are some home made extension methods, but they worked pretty well in previous version (VS RC). Html which is generated is also ok, no "Company.Phone"-like stuff. So I wonder, where all these keys with "Company" came from and what can I do with that? I appreciate any solution.

  • Help Optimizing MySQL Table (~ 500,000 records) and PHP Code.

    - by Pyrite
    I have a MySQL table that collects player data from various game servers (Urban Terror). The bot that collects the data runs 24/7, and currently the table is up to about 475,000+ records. Because of this, querying this table from PHP has become quite slow. I wonder what I can do on the database side of things to make it as optomized as possible, then I can focus on the application to query the database. The table is as follows: CREATE TABLE IF NOT EXISTS `people` ( `id` bigint(20) unsigned NOT NULL AUTO_INCREMENT, `name` varchar(40) NOT NULL, `ip` int(4) unsigned NOT NULL, `guid` varchar(32) NOT NULL, `server` int(4) unsigned NOT NULL, `date` int(11) NOT NULL, PRIMARY KEY (`id`), UNIQUE KEY `Person` (`name`,`ip`,`guid`), KEY `server` (`server`), KEY `date` (`date`), KEY `PlayerName` (`name`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 COMMENT='People that Play on Servers' AUTO_INCREMENT=475843 ; I'm storying the IPv4 (ip and server) as 4 byte integers, and using the MySQL functions NTOA(), etc to encode and decode, I heard that this way is faster, rather than varchar(15). The guid is a md5sum, 32 char hex. Date is stored as unix timestamp. I have a unique key on name, ip and guid, as to avoid duplicates of the same player. Do I have my keys setup right? Is the way I'm storing data efficient? Here is the code to query this table. You search for a name, ip, or guid, and it grabs the results of the query and cross references other records that match the name, ip, or guid from the results of the first query, and does it for each field. This is kind of hard to explain. But basically, if I search for one player by name, I'll see every other name he has used, every IP he has used and every GUID he has used. <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post"> Search: <input type="text" name="query" id="query" /><input type="submit" name="btnSubmit" value="Submit" /> </form> <?php if (!empty($_POST['query'])) { ?> <table cellspacing="1" id="1up_people" class="tablesorter" width="300"> <thead> <tr> <th>ID</th> <th>Player Name</th> <th>Player IP</th> <th>Player GUID</th> <th>Server</th> <th>Date</th> </tr> </thead> <tbody> <?php function super_unique($array) { $result = array_map("unserialize", array_unique(array_map("serialize", $array))); foreach ($result as $key => $value) { if ( is_array($value) ) { $result[$key] = super_unique($value); } } return $result; } if (!empty($_POST['query'])) { $query = trim($_POST['query']); $count = 0; $people = array(); $link = mysql_connect('localhost', 'mysqluser', 'yea right!'); if (!$link) { die('Could not connect: ' . mysql_error()); } mysql_select_db("1up"); $sql = "SELECT id, name, INET_NTOA(ip) AS ip, guid, INET_NTOA(server) AS server, date FROM 1up_people WHERE (name LIKE \"%$query%\" OR INET_NTOA(ip) LIKE \"%$query%\" OR guid LIKE \"%$query%\")"; $result = mysql_query($sql, $link); if (!$result) { die(mysql_error()); } // Now take the initial results and parse each column into its own array while ($row = mysql_fetch_array($result, MYSQL_NUM)) { $name = htmlspecialchars($row[1]); $people[] = array( 'id' => $row[0], 'name' => $name, 'ip' => $row[2], 'guid' => $row[3], 'server' => $row[4], 'date' => $row[5] ); } // now for each name, ip, guid in results, find additonal records $people2 = array(); foreach ($people AS $person) { $ip = $person['ip']; $sql = "SELECT id, name, INET_NTOA(ip) AS ip, guid, INET_NTOA(server) AS server, date FROM 1up_people WHERE (ip = \"$ip\")"; $result = mysql_query($sql, $link); while ($row = mysql_fetch_array($result, MYSQL_NUM)) { $name = htmlspecialchars($row[1]); $people2[] = array( 'id' => $row[0], 'name' => $name, 'ip' => $row[2], 'guid' => $row[3], 'server' => $row[4], 'date' => $row[5] ); } } $people3 = array(); foreach ($people AS $person) { $guid = $person['guid']; $sql = "SELECT id, name, INET_NTOA(ip) AS ip, guid, INET_NTOA(server) AS server, date FROM 1up_people WHERE (guid = \"$guid\")"; $result = mysql_query($sql, $link); while ($row = mysql_fetch_array($result, MYSQL_NUM)) { $name = htmlspecialchars($row[1]); $people3[] = array( 'id' => $row[0], 'name' => $name, 'ip' => $row[2], 'guid' => $row[3], 'server' => $row[4], 'date' => $row[5] ); } } $people4 = array(); foreach ($people AS $person) { $name = $person['name']; $sql = "SELECT id, name, INET_NTOA(ip) AS ip, guid, INET_NTOA(server) AS server, date FROM 1up_people WHERE (name = \"$name\")"; $result = mysql_query($sql, $link); while ($row = mysql_fetch_array($result, MYSQL_NUM)) { $name = htmlspecialchars($row[1]); $people4[] = array( 'id' => $row[0], 'name' => $name, 'ip' => $row[2], 'guid' => $row[3], 'server' => $row[4], 'date' => $row[5] ); } } // Combine people and people2 into just people $people = array_merge($people, $people2); $people = array_merge($people, $people3); $people = array_merge($people, $people4); $people = super_unique($people); foreach ($people AS $person) { $date = ($person['date']) ? date("M d, Y", $person['date']) : 'Before 8/1/10'; echo "<tr>\n"; echo "<td>".$person['id']."</td>"; echo "<td>".$person['name']."</td>"; echo "<td>".$person['ip']."</td>"; echo "<td>".$person['guid']."</td>"; echo "<td>".$person['server']."</td>"; echo "<td>".$date."</td>"; echo "</tr>\n"; $count++; } // Find Total Records //$result = mysql_query("SELECT id FROM 1up_people", $link); //$total = mysql_num_rows($result); mysql_close($link); } ?> </tbody> </table> <p> <?php echo $count."

  • Very different I/O performance in C++ on Windows

    - by Mr.Gate
    Hi all, I'm a new user and my english is not so good so I hope to be clear. We're facing a performance problem using large files (1GB or more) expecially (as it seems) when you try to grow them in size. Anyway... to verify our sensations we tryed the following (on Win 7 64Bit, 4core, 8GB Ram, 32 bit code compiled with VC2008) a) Open an unexisting file. Write it from the beginning up to 1Gb in 1Mb slots. Now you have a 1Gb file. Now randomize 10000 positions within that file, seek to that position and write 50 bytes in each position, no matter what you write. Close the file and look at the results. Time to create the file is quite fast (about 0.3"), time to write 10000 times is fast all the same (about 0.03"). Very good, this is the beginnig. Now try something else... b) Open an unexisting file, seek to 1Gb-1byte and write just 1 byte. Now you have another 1Gb file. Follow the next steps exactly same way of case 'a', close the file and look at the results. Time to create the file is the faster you can imagine (about 0.00009") but write time is something you can't believe.... about 90"!!!!! b.1) Open an unexisting file, don't write any byte. Act as before, ramdomizing, seeking and writing, close the file and look at the result. Time to write is long all the same: about 90"!!!!! Ok... this is quite amazing. But there's more! c) Open again the file you crated in case 'a', don't truncate it... randomize again 10000 positions and act as before. You're fast as before, about 0,03" to write 10000 times. This sounds Ok... try another step. d) Now open the file you created in case 'b', don't truncate it... randomize again 10000 positions and act as before. You're slow again and again, but the time is reduced to... 45"!! Maybe, trying again, the time will reduce. I actually wonder why... Any Idea? The following is part of the code I used to test what I told in previuos cases (you'll have to change someting in order to have a clean compilation, I just cut & paste from some source code, sorry). The sample can read and write, in random, ordered or reverse ordered mode, but write only in random order is the clearest test.

  • Very different IO performance in C/C++

    - by Roberto Tirabassi
    Hi all, I'm a new user and my english is not so good so I hope to be clear. We're facing a performance problem using large files (1GB or more) expecially (as it seems) when you try to grow them in size. Anyway... to verify our sensations we tryed the following (on Win 7 64Bit, 4core, 8GB Ram, 32 bit code compiled with VC2008) a) Open an unexisting file. Write it from the beginning up to 1Gb in 1Mb slots. Now you have a 1Gb file. Now randomize 10000 positions within that file, seek to that position and write 50 bytes in each position, no matter what you write. Close the file and look at the results. Time to create the file is quite fast (about 0.3"), time to write 10000 times is fast all the same (about 0.03"). Very good, this is the beginnig. Now try something else... b) Open an unexisting file, seek to 1Gb-1byte and write just 1 byte. Now you have another 1Gb file. Follow the next steps exactly same way of case 'a', close the file and look at the results. Time to create the file is the faster you can imagine (about 0.00009") but write time is something you can't believe.... about 90"!!!!! b.1) Open an unexisting file, don't write any byte. Act as before, ramdomizing, seeking and writing, close the file and look at the result. Time to write is long all the same: about 90"!!!!! Ok... this is quite amazing. But there's more! c) Open again the file you crated in case 'a', don't truncate it... randomize again 10000 positions and act as before. You're fast as before, about 0,03" to write 10000 times. This sounds Ok... try another step. d) Now open the file you created in case 'b', don't truncate it... randomize again 10000 positions and act as before. You're slow again and again, but the time is reduced to... 45"!! Maybe, trying again, the time will reduce. I actually wonder why... Any Idea? The following is part of the code I used to test what I told in previuos cases (you'll have to change someting in order to have a clean compilation, I just cut & paste from some source code, sorry).

  • Thread not behaving correctly

    - by ivor
    Hello, I wonder if anyone can help me to understand where I could be going wrong with this code; Basically I'm working on a turorial and calling the class below from another class - and it is getting the following error; Exception in thread "Thread-1" java.lang.NullPointerException at org.newdawn.spaceinvaders.TCPChat.run(TCPChat.java:322) at java.lang.Thread.run(Unknown Source) I realise the error is beibg flagged in another class- but I have tested the other class with a small class which sets up a separate thread - and it works fine, but as soon as I try and implement a new thread in this class - it causes all sorts of problems. Am I setting up the thread correctly in this class? Basically I can set up a thread in this class, with a test loop and it's fine, but when I bring in the functionality of the rest of the game it sometimes hangs, or does not display at all. Any suggestions on where I could be going wrong would be greatly appreciated.
