• PHP-FPM stops responding and dies [migrated]

  - by user12361

  I'm running Drupal 6 with Nginx 1.5.1 and PHP-FPM (PHP 5.3.26) on a 1GB single core VPS with 3GB of swap space on SSD storage. I just switched from shared hosting to this unmanaged VPS because my site was getting too heavy, so I'm still learning the ropes. I have moderately high traffic, I don't really monitor it closely but Google Adsense usually record close to 30K page views/day. I usually have 50 to 80 authenticated users logged in and a few hundred more anonymous users hitting the Boost static HTML cache at any given moment. The problem I'm having is that PHP-FPM frequently stops responding, resulting in Nginx 502 or 504 errors. I swear I have read every page on the internet about this issue, which seems fairly common, and I've tried endless combinations of configurations, and I can't find a good solution. After restarting Nginx and PHP-FPM, the site runs really fast for a while, and then without warning it simply stops responding. I get a white screen while the browser waits on the server, and after about 30 seconds to a minute it throws an Nginx 502 or 504 error. Sometimes it runs well for 2 minutes, sometimes 5 minutes, sometimes 5 hours, but it always ends up hanging. When I find the server in this state, there is still plenty of free memory (500MB or more) and no major CPU usage, the control and worker PHP-FPM processes are still present, and the server is still pingable and usable via SSH. A reload of PHP-FPM via the init script revives it again. The hangups don't seem to correspond to the amount of traffic, because I observed this behavior consistently when I was testing this configuration on a development VPS with no traffic at all. I've been constantly tweaking the settings, but I can't definitively eliminate the problem. I set Nginx workers to just 1. In the PHP-FPM config I have tried all three of the process managers. "Dynamic" is definitely the least reliable, consistently hanging up after only a few minutes. "Static" also has been unreliable and unpredictable. The least buggy has been "ondemand", but even that is failing me, sometimes after as much as 12 to 24 hours. But I can't leave the server unattended because PHP-FPM dies and never comes back on its own. I tried adjusting the pm.max_children value from as low as 3 to as high as 50, doesn't make a lot of difference, but I currently have it at 10. Same thing for the spare servers values. I also have set pm.max_requests anywhere from 30 to unlimited, and it doesn't seem to make a difference. According to the logs, the PHP-FPM processes are not exiting with SIGSEGV or SIGBUS, but rather with SIGTERM. I get a lot of lines like: WARNING: [pool www] child 3739, script '/var/www/drupal6/index.php' (request: "GET /index.php") execution timed out (38.739494 sec), terminating and: WARNING: [pool www] child 3738 exited on signal 15 (SIGTERM) after 50.004380 seconds from start I actually found several articles that recommend doing a graceful reload of PHP-FPM via cron every few minutes or hours to circumvent this issue. So that's what I did, "/etc/init.d/php-fpm reload" every 5 minutes. So far, it's keeping the lights on. But it feels like a dreadful hack. Is PHP-FPM really that unreliable? Is there anything else I can do? Thanks a lot!

• MySQL Server 5.6 defaults changes

  - by user12626240

  We're improving the MySQL Server defaults, as announced by Tomas Ulin at MySQL Connect. Here's what we're changing:  Setting  Old  New  Notes back_log  50  50 + ( max_connections / 5 ) capped at 900 binlog_checksum  off  CRC32  New variable in 5.6 binlog_row_event_max_size  1k  8k flush_time  1800  Windows changes from 1800 to 0  Was already 0 on other platforms host_cache_size  128  128 + 1 for each of the first 500 max_connections + 1 for every 20 max_connections over 500, capped at 2000  New variable in 5.6 innodb_autoextend_increment  8  64  Now affects *.ibd files. 64 is 64 megabytes innodb_buffer_pool_instances  0  8. On 32 bit Windows only, if innodb_buffer_pool_size is greater than 1300M, default is innodb_buffer_pool_size / 128M innodb_concurrency_tickets  500  5000 innodb_file_per_table  off  on innodb_log_file_size  5M  48M  InnoDB will always change size to match my.cnf value. Also see innodb_log_compressed_pages and binlog_row_image innodb_old_blocks_time 0  1000 1 second innodb_open_files  300  300; if innodb_file_per_table is ON, higher of table_open_cache or 300 innodb_purge_batch_size  20  300 innodb_purge_threads  0  1 innodb_stats_on_metadata  on  off join_buffer_size 128k  256k max_allowed_packet  1M  4M max_connect_errors  10  100 open_files_limit  0  5000  See note 1 query_cache_size  0  1M query_cache_type  on/1  off/0 sort_buffer_size  2M  256k sql_mode  none  NO_ENGINE_SUBSTITUTION  See later post about default my.cnf for STRICT_TRANS_TABLES sync_master_info  0  10000  Recommend: master_info_repository=table sync_relay_log  0  10000 sync_relay_log_info  0  10000  Recommend: relay_log_info_repository=table. Also see Replication Relay and Status Logs table_definition_cache  400  400 + table_open_cache / 2, capped at 2000 table_open_cache  400  2000   Also see table_open_cache_instances thread_cache_size  0  8 + max_connections/100, capped at 100 Note 1: In 5.5 there was already a rule to make open_files_limit 10 + max_connections + table_cache_size * 2 if that was higher than the user-specified value. Now uses the higher of that and (5000 or what you specify). We are also adding a new default my.cnf file and guided instructions on the key settings to adjust. More on this in a later post. We're also providing a page with suggestions for settings to improve backwards compatibility. The old example files like my-huge.cnf are obsolete. Some of the improvements are present from 5.6.6 and the rest are coming. These are ideas, and until they are in an official GA release, they are subject to change. As part of this work I reviewed every old server setting plus many hundreds of emails of feedback and testing results from inside and outside Oracle's MySQL Support team and the many excellent blog entries and comments from others over the years, including from many MySQL Gurus out there, like Baron, Sheeri, Ronald, Schlomi, Giuseppe and Mark Callaghan. With these changes we're trying to make it easier to set up the server by adjusting only a few settings that will cause others to be set. This happens only at server startup and only applies to variables where you haven't set a value. You'll see a similar approach used for the Performance Schema. The Gurus don't need this but for many newcomers the defaults will be very useful. Possibly the most unusual change is the way we vary the setting for innodb_buffer_pool_instances for 32-bit Windows. This is because we've found that DLLs with specified load addresses often fragment the limited four gigabyte 32-bit address space and make it impossible to allocate more than about 1300 megabytes of contiguous address space for the InnoDB buffer pool. The smaller requests for many pools are more likely to succeed. If you change the value of innodb_log_file_size in my.cnf you will see a message like this in the error log file at the next restart, instead of the old error message: [Warning] InnoDB: Resizing redo log from 2*64 to 5*128 pages, LSN=5735153 One of the biggest challenges for the defaults is the millions of installations on a huge range of systems, from point of sale terminals and routers though shared hosting or end user systems and on to major servers with lots of CPU cores, hundreds of gigabytes of RAM and terabytes of fast disk space. Our past defaults were for the smaller systems and these change that to larger shared hosting or shared end user systems, still with a bias towards the smaller end. There is a bias in favour of OLTP workloads, so reporting systems may need more changes. Where there is a conflict between the best settings for benchmarks and normal use, we've favoured production, not benchmarks. We're very interested in your feedback, comments and suggestions.

SQL PLAN DIRECTIVES, SQL PLAN DIRECTIVES???retention ???53?: Package: DBMS_SPD This package provides subprograms for managing Sql Plan Directives(SPD). SPD are objects generated automatically by Oracle server. For example, if server detects that the single table cardinality estimated by optimizer is off from the actual number of rows returned when accessing the table, it will automatically create a directive to do dynamic sampling for the table. When any Sql statement referencing the table is compiled, optimizer will perform dynamic sampling for the table to get more accurate estimate. Notes: DBMSL_SPD is a invoker-rights package. The invoker requires ADMINISTER SQL MANAGEMENT OBJECT privilege for executing most of the subprograms of this package. Also the subprograms commit the current transaction (if any), perform the operation and commit it again. DBA view dba_sql_plan_directives shows all the directives created in the system and the view dba_sql_plan_dir_objects displays the objects that are included in the directives. -- Default value for SPD_RETENTION_WEEKS SPD_RETENTION_WEEKS_DEFAULT CONSTANT varchar2(4) := '53'; | STATE : NEW : Newly created directive. | : MISSING_STATS : The directive objects do not | have relevant stats. | : HAS_STATS : The objects have stats. | : PERMANENT : A permanent directive.

Procedure: flush_sql_plan_directive This procedure allows manually flushing the Sql Plan directives that are automatically recorded in SGA memory while executing sql statements. The information recorded in SGA are periodically flushed by oracle background processes.

• OpenCV Mat creation memory leak

  - by Royi Freifeld

  My memory is getting full fairly quick once using the next piece of code. Valgrind shows a memory leak, but everything is allocated on stack and (supposed to be) freed once the function ends. void mult_run_time(int rows, int cols) { Mat matrix(rows,cols,CV_32SC1); Mat row_vec(cols,1,CV_32SC1); /* initialize vector and matrix */ for (int col = 0; col < cols; ++col) { for (int row = 0; row < rows; ++row) { matrix.at<unsigned long>(row,col) = rand() % ULONG_MAX; } row_vec.at<unsigned long>(1,col) = rand() % ULONG_MAX; } /* end initialization of vector and matrix*/ matrix*row_vec; } int main() { for (int row = 0; row < 20; ++row) { for (int col = 0; col < 20; ++col) { mult_run_time(row,col); } } return 0; } Valgrind shows that there is a memory leak in line Mat row_vec(cols,1,CV_32CS1): ==9201== 24,320 bytes in 380 blocks are definitely lost in loss record 50 of 50 ==9201== at 0x4026864: malloc (vg_replace_malloc.c:236) ==9201== by 0x40C0A8B: cv::fastMalloc(unsigned int) (in /usr/local/lib/libopencv_core.so.2.3.1) ==9201== by 0x41914E3: cv::Mat::create(int, int const*, int) (in /usr/local/lib/libopencv_core.so.2.3.1) ==9201== by 0x8048BE4: cv::Mat::create(int, int, int) (mat.hpp:368) ==9201== by 0x8048B2A: cv::Mat::Mat(int, int, int) (mat.hpp:68) ==9201== by 0x80488B0: mult_run_time(int, int) (mat_by_vec_mult.cpp:26) ==9201== by 0x80489F5: main (mat_by_vec_mult.cpp:59) Is it a known bug in OpenCV or am I missing something?

• Problems with builds on TFS 2010 and resolving dependencies

  - by Jimmy Engtröm

  Hi I have a project that works great on my machine (and production servers). It's a VS2010 project running C#3.5. When letting my build server build the solution it can't resolve a couple of my third party dll's. Error message: C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Microsoft.Common.targets(1360,9): warning MSB3268: The primary reference "Third.Party.Assembly, Version=50.11.2.0, Culture=neutral, PublicKeyToken=0561a7c6dbd6f0ea, processorArchitecture=MSIL" could not be resolved because it has an indirect dependency on the framework assembly "Microsoft.VisualBasic.Compatibility, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" which could not be resolved in the currently targeted framework. ".NETFramework,Version=v3.5". To resolve this problem, either remove the reference "Third.Party.Assembly, Version=50.11.2.0, Culture=neutral, PublicKeyToken=0561a7c6dbd6f0ea, processorArchitecture=MSIL" or retarget your application to a framework version which contains "Microsoft.VisualBasic.Compatibility, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a". [d:\Builds\3\mySolution.sln] Everything compiles and runs great on my machine, but the build server seem to struggle. I think the Third.Party.Assembly is written in VB.net. Since the assembly is third party I can't remove the reference to "Microsoft.VisualBasic.Compatibility" and since I don't get any warnings on my computer could it really be that I'm running v3.5? Any suggestions? /Jimmy

• How to use multiple DisplayName attribute using Entity Framework and ASP.Net Mvc 2

  - by Picflight

  Depending on where I use my Class, I want to be able to show a different DisplayName. I have the following class: [MetadataType(typeof(PortalMetaData))] [System.Web.Mvc.Bind(Exclude = "PortalId")] public partial class Portal { public Portal() { this.Created = DateTime.Now; } } public class PortalMetaData { [Required(ErrorMessage = "Portal name is required")] [StringLength(50, ErrorMessage = "Portal name must be under 50 characters")] public object PortalName { get; set; } [Required(ErrorMessage = "Description is required")] public object Description { get; set; } } I have a corresponding Table in the database Portal I use the Portal table with a PortalController for the Site Admin to update the records in the Portal Table. I want another user with a different Role (AsstAdmin) to be able to update this table as well. To facilitate that I am thinking of creating a separate partial class that somehow links back to the Portal Model. This would allow me to display limited Fields for update by the AsstAdmin and I can display a different name for the Field as well. How can I accomplish this task? If I add the following class which inherits from Portal than I get an exception: Unable to cast object of type 'Project1.Mvc.Models.Portal' to type 'Prpject1.Mvc.Models.Site'. [MetadataType(typeof(SiteMetaData))] public class Site : Portal { public Site() { } } public class SiteMetaData { [Required(DisplayName = "Site Description")] public object Description { get; set; } }

• maxlength attribute of a text box from the DataAnnotations StringLength in MVC2

  - by Pervez Choudhury

  I am working on an MVC2 application and want to set the maxlength attributes of the text inputs. I have already defined the stringlength attribute on the Model object using data annotations and it is validating the length of entered strings correctly. I do not want to repeat the same setting in my views by setting the max length attribute manually when the model already has the information. Is there any way to do this? Code snippets below: From the Model: [Required, StringLength(50)] public string Address1 { get; set; } From the View: <%= Html.LabelFor(model => model.Address1) %> <%= Html.TextBoxFor(model => model.Address1, new { @class = "text long" })%> <%= Html.ValidationMessageFor(model => model.Address1) %> What I want to avoid doing is: <%= Html.TextBoxFor(model => model.Address1, new { @class = "text long", maxlength="50" })%> Is there any way to do this?

• ASP .NET, Javascript, AjaxControlToolkit - get results with Selenium??

  - by Seth

  I'm a newbie to web stuff. However, I wish to scrape some data from multiple websites. I'm currently using the following technologies: Selenium; Python; and BeautifulSoup; I believe the site I am trying to scrape is using a combination of ASP.NET, javascript and the AjaxControlToolkit. I believe the key results I am looking for are in the following script: <script type="text/javascript"> //<![CDATA[ Sys.Application.initialize(); Sys.Application.add_init(function() { $create(AjaxControlToolkit.AutoCompleteBehavior, {"completionInterval":50,"completionListCssClass":"autocomplete_completionListElement","completionListItemCssClass":"autocomplete_listItem","completionSetCount":20,"delimiterCharacters":"","highlightedItemCssClass":"autocomplete_highlightedListItem","id":"ctl00_ContentPlaceHolder1_AutoCompleteExtender1","minimumPrefixLength":4,"serviceMethod":"GetSchoolNames","servicePath":"AutoComplete.asmx"}, {"itemSelected":ItemSelected}, null, $get("ctl00_ContentPlaceHolder1_SchoolNameTextBox")); }); Sys.Application.add_init(function() { $create(AjaxControlToolkit.AutoCompleteBehavior, {"completionInterval":50,"completionListCssClass":"autocomplete_completionListElement","completionListItemCssClass":"autocomplete_listItem","delimiterCharacters":"","highlightedItemCssClass":"autocomplete_highlightedListItem","id":"ctl00_ContentPlaceHolder1_AutoCompleteExtender2","minimumPrefixLength":2,"serviceMethod":"GetSuburbNames","servicePath":"AutoComplete.asmx"}, null, null, $get("ctl00_ContentPlaceHolder1_SuburbTownTextBox")); }); //]]> </script> Is there an easy way to get the results of the above script processed using Selenium so that I may pass it using BeautifulSoup?

• Problem using FtpWebRequest to append to file on a mainframe

  - by MusiGenesis

  I am using FtpWebRequest to append data to a mainframe file. Each record appended is 50 characters long, and I am adding them one record at a time. In our development environment, we do not have a mainframe, so my code was written and tested FTPing to a Windows-based FTP site instead of a mainframe. Initially, I was writing each record using a StreamWriter (using the stream from the FtpWebRequest) and writing each record using WriteLine (which automatically adds a CR/LF to the end). When we ran this for the first time in the test environment (in which we're writing to an actual MVS mainframe), our mainframe contact said the CR/LFs were not able to be read by his program (a green-screen mainframe program of some sort - he's sent me screen captures, which is all I know of it). I changed our code to use Write instead of WriteLine, but now my code executes successfully (i.e no thrown exceptions) when writing multiple records, but no matter how many records we append, he is only able to "see" the first record - according to his mainframe program, there is only one 50-character record in the file. I'm guessing that to fix this, I need to write some other line-delimiting character into the end of the stream (instead of CR/LF) that the mainframe will recognize as a record delimiter. Anybody know what this is, or how else I can fix this problem?

• Mulitple full joins in Postgres is slow

  - by blast83

  I have a program to use the IMDB database and am having very slow performance on my query. It appears that it doesn't use my where condition until after it materializes everything.

As you can see, the end result is 4 tuples but it seems like it should be a fast join by using the available index after it limited it down with the name clause, although very complex.

• jQuery UI - Close Dialog When Clicked Outside

  - by Sonny

  I have a jQuery UI Dialog that gets displayed when specific elements are clicked. I would like to close the dialog if a click occurs anywhere other than on those triggering elements or the dialog itself. Here's the code for opening the dialog: $(document).ready(function() { var $field_hint = $('<div></div>') .dialog({ autoOpen: false, minHeight: 50, resizable: false, width: 375 }); $('.hint').click(function() { var $hint = $(this); $field_hint.html($hint.html()); $field_hint.dialog('option', 'position', [162, $hint.offset().top + 25]); $field_hint.dialog('option', 'title', $hint.siblings('label').html()); $field_hint.dialog('open'); }); /*$(document).click(function() { $field_hint.dialog('close'); });*/ }); If I uncomment the last part, the dialog never opens. I assume it's because the same click that opens the dialog is closing it again. Final Working Code $(document).ready(function() { var $field_hint = $('<div></div>') .dialog({ autoOpen: false, minHeight: 50, resizable: false, width: 375 }) .bind('clickoutside', function(e) { if (!$(e.target).filter('.hint').length) { $field_hint.dialog('close'); } }); $('.hint').click(function() { var $hint = $(this); $field_hint.html($hint.html()); $field_hint.dialog('option', 'position', [162, $hint.offset().top + 25]); $field_hint.dialog('option', 'title', $hint.siblings('label').html()); $field_hint.dialog('open'); }); });

• How to clone a Model using Entity Framework and ASP.Net Mvc 2

  - by Picflight

  I have the following class: [MetadataType(typeof(PortalMetaData))] [System.Web.Mvc.Bind(Exclude = "PortalId")] public partial class Portal { public Portal() { this.Created = DateTime.Now; } } public class PortalMetaData { [Required(ErrorMessage = "Portal name is required")] [StringLength(50, ErrorMessage = "Portal name must be under 50 characters")] public object PortalName { get; set; } [Required(ErrorMessage = "Description is required")] public object Description { get; set; } } I have a corresponding Table in the database Portal I use the Portal table with a PortalController for the Site Admin to update the records in the Portal Table. I want another user with a different Role (AsstAdmin) to be able to update this table as well. To facilitate that I am thinking of creating a separate partial class that somehow links back to the Portal Model. This would allow me to display limited Fields for update by the AsstAdmin and I can display a different name for the Field as well. How can I accomplish this task? If I add the following class which inherits from Portal than I get an exception: Unable to cast object of type 'Project1.Mvc.Models.Portal' to type 'Prpject1.Mvc.Models.Site'. [MetadataType(typeof(SiteMetaData))] public class Site : Portal { public Site() { } } public class SiteMetaData { [Required(DisplayName = "Site Description")] public object Description { get; set; } }

Can someone send me a link to an example that only log the message into the log file? /Thanks

• How can I line up WPF items in a Horizontal WrapPanel so they line up based on an arbitrary vertical

  - by Scott Whitlock

  I'm trying to create a View in WPF and having a hard time figuring out how to set it up. Here's what I'm trying to build: My ViewModel exposes an IEnumerable property called Items Each item is an event on a timeline, and each one implements ITimelineItem The ViewModel for each item has it's own DataTemplate to to display it I want to display all the items on the timeline connected by a line. I'm thinking a WrapPanel inside of a ListView would work well for this. However, the height of each item will vary depending on the information it displays. Some items will have graphic objects right on the line (like a circle or a diamond, or whatever), and some have annotations above or below the line. So it seems complicated to me. It seems that each item on the timeline has to render its own segment of the line. That's fine. But the distance between the top of the item to the line (and the bottom of the item to the line) could vary. If one item has the line 50 px down from the top and the next item has the line 100 px down from the top, then the first item needs 50 px of padding so that the line segments add up. I think I could solve that problem, however, we only need to add padding if these two items are on the same line in the WrapPanel! Let's say there are 5 items and only room on the screen for 3 across... the WrapPanel will put the other two on the next line. That's ok, but that means only the first 3 need to pad together, and the last 2 need to pad together. This is what's giving me a headache. Is there another approach I could look at?

• Is it possible to seletively color a wrapping TextBlock in Silverlight/WPF

  - by joemoe

  For instance, if I have a TextBlock: "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum." I want the first 10% of this TextBlock, such that the font color should be red, and the rest should be green. This perhaps means it would color the "Lorem ipsum dolor sit amet, consectetur adipisici", and part of the "n". Basically pixel-wise font coloring instead of character-wise. Another important behavior is that the percentage respects the wrapping, in that if 50% of the TextBlock contents is colored, it should mean 50% of the text in reading order is colored, and not the first half of the block. For example, this is a similar question (with correct answers), but regarding Label/TextBlocks with no wrapping: http://stackoverflow.com/questions/2394421/is-it-possible-to-seletively-color-a-label-in-silverlight

• How to make a UITextField move up when keyboard is present

  - by philfreo

  EDIT: Over 1k views with 3 upvotes? If this question is helpful, vote it up :) With the iPhone SDK: I have a UIView with UITextFields that brings up a keyboard. I need it to be able to: Allow scrolling of the contents of the UIScrollView to see the other text fields once the keyboard is brought up Automatically "jump" (by scrolling up) or shortening I know that I need a UIScrollView. I've tried changing the class of my UIView to a UIScrollView but I'm still unable to scroll the textboxes up or down. Do I need both a UIView and a UIScrollView? Does one go inside the other? [EDIT: I now know that you want a UIView inside of a UIScrollView, and the trick is to programatically set the content size of the UIScrollView to the frame size of the UIView.] Then what needs to be implemented in order to automatically scroll to the active text field? Ideally as much of the setup of the components as possible will be done in Interface Builder. I'd like to only write code for what needs it. Note: the UIView (or UIScrollView) that I'm working with is brought up by a tabbar (UITabBar), which needs to function as normal. Edit: I am adding the scroll bar just for when the keyboard comes up. Even though it's not needed, I feel like it provides a better interface because then the user can scroll and change textboxes, for example. I've got it working where I change the frame size of the UIScrollView when the keyboard goes up and down. I'm simply using: -(void)textFieldDidBeginEditing:(UITextField *)textField { //Keyboard becomes visible scrollView.frame = CGRectMake(scrollView.frame.origin.x, scrollView.frame.origin.y, scrollView.frame.size.width, scrollView.frame.size.height - 215 + 50); //resize } -(void)textFieldDidEndEditing:(UITextField *)textField { //keyboard will hide scrollView.frame = CGRectMake(scrollView.frame.origin.x, scrollView.frame.origin.y, scrollView.frame.size.width, scrollView.frame.size.height + 215 - 50); //resize } However this doesn't automatically "move up" or center the lower text fields in the visible area, which is what I would really like.

• How to improve Java perfomance on Informix for Windows

  - by Michal Niklas

  I have problem with performance of Java UDR functions on Informix on Windows. On this server I already have some functions in C and SPL. I chose one function to write it in those 3 languages and I measured performance of this function on test table. Function calculates some kind of checksum so it not use any db libraries etc. only string and math operations. I observed performance on 30k records with SQL like: select function(txt) from _tmp_perf_test and I changed function to 'function_c, function_spl or function_java. My performance tests showed that C function is the fastest, SPL function is about 5 times slower, where Java is 100 (one hundred!) times slower than C. I checked it few times and 1:100 ratio didn't improve. I changed Java function to simply return length of the string but even this do not help so it looks, that there is general problem with Java function invocation, because there was no difference in time between Java function that calculate checksum and Java function that returns length of the string. I increased JVM_MAX_HEAP_SIZE to 128 and it not helped too. I use IBM Informix Dynamic Server Version 11.50.TC6DE. The same test on Linux server: IBM Informix Dynamic Server Version 11.50.FC6 show more "normal" results, i.e. Java is slower from C and SPL but only 2 to 5 times. What can I do to improve Java performance on Informix server on Windows?

• WCF Service Throttling

  - by Mubashar Ahmad

  Dear All I have a WCF Service Deployed in a Console App with BasicHTTPBinding and SSL enabled on port using NetSH command and more over following attribute is set as well. [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] And also i have set the Throttling behavior as <serviceThrottling maxConcurrentCalls="2147483647" maxConcurrentSessions="2147483647" maxConcurrentInstances="2147483647" /> On the other hand i have created a Test Client(for load test) that initiates multiple clients simultaneously(multiple threads) and performs transactions on server. everything seems fine and working properly but on server the CPU utilization is doesn't grow so i added some logging to view the number of concurrent calls to the server and found that its never went over 6. i have reviewed the performance counter logging code more than twice and it seems fine to me. So i want to ask where is the problem in this situation and one more thing i haven't specified any kind of ContextMode or ConcurrencyMode yet. After this Post I noticed that whenever i start another Intance of Test Client my concurrent Server Calls counter increase to 2 like if i am running only 1 instance the maximum Concurrent Rcvd Calls will be 2 and if there are two instance the same value goes to 4 and so on. Is there any limit of Number of WCF Calls from once process? Looking for help Mubashar *Added on 17-March******************* Today i ran another test with one test client(with 50 concurrent users) on the same machine on which the server is running this time i am getting exact result what i wanted it to show i.e. Maximum concurrent Calls Rcvd by Server = 50 but i need to do it the same on others machines as well. Can anybody help me on this.

• Unable to convert from Julian INT date to regular TSQL Datetime

  - by Bluehiro

  Help me Stackoverflow, I'm close to going all "HULK SMASH" on my keyboard over this issue. I have researched carefully but I'm obviously not getting something right. I am working with a Julian dates referenced from a proprietary tool (Platinum SQL?), though I'm working in SQL 2005. I can convert their "special" version of Julian into datetime when I run a select statement. Unfortunately it will not insert into a datetime column, I get the following error when I try: The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value. So I can't setup datetime criteria for running a report off of the Stored Procedure. Original Value: 733416 Equivalent Calendar Value: 01-09-2009 Below is my code... I'm so close but I can't quite see what's wrong, I need my convert statement to actually convert the Julian value (733416) into a compatible TSQL DATETIME value. SELECT org_id, CASE WHEN date_applied = 0 THEN '00-00-00' ELSE convert(char(50),dateadd(day,date_applied-729960,convert(datetime, '07-25-99')),101) END AS date_applied, CASE WHEN date_posted = 0 THEN '00-00-00' ELSE convert(char(50),dateadd(day,date_posted-729960,convert(datetime, '07-25-99')),101) END AS date_posted from general_vw

• drawing different quartz 2d

  - by Cosizzle

  Hello, I'm trying to make a small application or demo thats a tab bar application. Each bar item loads in a new view. I've created a quartzView class that is called on by the controller: - (void)viewDidLoad { quartzView *drawingView = [[quartzView alloc] initWithFrame:CGRectMake(0,0,320,480)]; [self.view addSubview:drawingView]; [super viewDidLoad]; } From my understanding, the drawRect method must be triggered in order to render the object and to draw it. This is my quartzView class: #import "quartzView.h" @implementation quartzView #pragma mark shapes // Blue Circle - (void)drawRect:(CGRect)rect { NSLog(@"Trying to draw..."); CGContextRef ctx = UIGraphicsGetCurrentContext(); //get the current context CGContextClearRect(ctx, rect); //clear off the screen //draw a red square CGContextSetRGBFillColor(ctx, 255, 0, 0, 1); CGContextFillRect(ctx, CGRectMake(10, 10, 50, 50)); } // ==================================================================================================== #pragma mark - - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { // Initialization code } return self; } - (void)dealloc { [super dealloc]; } @end So how would I go about to say, if the view is view one, draw a square if it's view two draw a circle. And so on.

• How do I eliminate Error 3002?

  - by Andrew

  Say I have the following table definitions in SQL Server 2008: CREATE TABLE Person (PersonId INT IDENTITY NOT NULL PRIMARY KEY, Name VARCHAR(50) NOT NULL, ManyMoreIrrelevantColumns VARCHAR(MAX) NOT NULL) CREATE TABLE Model (ModelId INT IDENTITY NOT NULL PRIMARY KEY, ModelName VARCHAR(50) NOT NULL, Description VARCHAR(200) NULL) CREATE TABLE ModelScore (ModelId INT NOT NULL REFERENCES Model (ModelId), Score INT NOT NULL, Definition VARCHAR(100) NULL, PRIMARY KEY (ModelId, Score)) CREATE TABLE PersonModelScore (PersonId INT NOT NULL REFERENCES Person (PersonId), ModelId INT NOT NULL, Score INT NOT NULL, PRIMARY KEY (PersonId, ModelId), FOREIGN KEY (ModelId, Score) REFERENCES ModelScore (ModelId, Score)) The idea here is that each Person may have only one ModelScore per Model, but each Person may have a score for any number of defined Models. As far as I can tell, this SQL should enforce these constraints naturally. The ModelScore has a particular "meaning," which is contained in the Definition. Nothing earth-shattering there. Now, I try translating this into Entity Framework using the designer. After updating the model from the database and doing some editing, I have a Person object, a Model object, and a ModelScore object. PersonModelScore, being a join table, is not an object but rather is included as an association with some other name (let's say ModelScorePersonAssociation). The mapping details for the association are as follows: - Association - Maps to PersonModelScore - ModelScore ModelId : Int32 <=> ModelId : int Score : Int32 <=> Score : int - Person PersonId : Int32 <=> PersonId : int On the right-hand side, the ModelId and PersonId values have primary key symbols, but the Score value does not. Upon compilation, I get: Error 3002: Problem in Mapping Fragment starting at line 5190: Potential runtime violation of table PersonModelScore's keys (PersonModelScore.ModelId, PersonModelScore.PersonId): Columns (PersonModelScore.PersonId, PersonModelScore.ModelId) are mapped to EntitySet ModelScorePersonAssociation's properties (ModelScorePersonAssociation.Person.PersonId, ModelScorePersonAssociation.ModelScore.ModelId) on the conceptual side but they do not form the EntitySet's key properties (ModelScorePersonAssociation.ModelScore.ModelId, ModelScorePersonAssociation.ModelScore.Score, ModelScorePersonAssociation.Person.PersonId). What have I done wrong in the designer or otherwise, and how can I fix the error? Many thanks!
