  • PHP not displaying any errors

    - by chutsu
    I've got ubuntu 10.04 installed, as well as: lighttpd mysql/php Now my problem is that my php scripts can be executed and has access to MySQL database, however I'm having problems getting php to display all errors when running. The result of a failed php run is a blank page. I tried setting the display errors on in php.ini in /etc/php5/cgi/php.ini I've also tried adding these two lines in the source to force errors on, to no avail. ini_set('display_errors', '1'); error_reporting(E_ALL); What should I do? Thanks

  • Is it bad to have a very full hard drive on a high traffic database server?

    - by MikeN
    Running an Ubuntu server with MySQL for a high traffic production database server. Nothing else is running on the machine except the MySQL instance. We store daily database backups on the DB server, is there any performance hit or reason why we should keep the hard disk relatively empty? If the disk is filled up to 86%+ with the database and all of the backups, does it hurt performance at all? So would the DB server running with 86-90%+ full capacity perform less well in any way than the server running with only a 10% full disk? The total disk size on the server is over 1 TB so even 10% of the disk should be enough for basic O/S swapping and such.

  • PHP Runs Very Slow on IIS7. Need Help optimizing our config

    - by Kendor
    Am running a PHP based web app on our Windows 2008 cloud-based server. The app, which runs fine outside of our environment (e.g. a different IIS server), but is VERY slow in our environment. Based on googling this is a relatively common situation. I installed PHP and MySQL via the IIS web deployment method... Here's our setup: Windows 2008 Server Enterprise SP2 (32-bit) Microsoft-IIS/7.0 MySQL client version: mysqlnd 5.0.8-dev - 20102224 $Revision: 321634 $ PHP extension: mysqli Update for IIS 7.0 FastCGI Windows Cache Extension 1.1 for PHP 5.3 I had read elsewhere that ipv6 might be an issue, so I turned this off on the network adapter. The app is using: localhost as its connection Be easy on me, as I'm a bit green about some of these components... Also, rewriting the PHP app or modifying it is NOT an option. I'm reasonably SURE that our config is the issue.

  • Apache Web Server character encoding

    - by OBY
    I've recently transferred my webapp from my localhost (LH) to a VPS, and have had hebrew chars-encoding probs since. Whenever I send a request with a heb-char it results in "?????" saved to the DB. My LH config was tomcat6, MySQL, and centOS 6.2, opened to the web. In the VPS env I'm behind an Apache Web Server, and the rest is quite the same (though I haven't done anything to its installation). Please note I already have had this problem before, on my LH when the request was sent from IE/chrome (not FF!). The solution was to apply a filter on the the context and change the char-type to UTF-8. My webapp content char-encode is utf-8, MySql server set to utf8 using charset utf8;, and my centOS set to iw_IL.UTF8 using export LANG=iw_IL.UTF8. When I use locale the bash output seems to be set correctly. Any suggestions?

  • XAMPP won't start because I'm already running MySQL on port 3306

    - by JellicleCat
    I'm trying to start XAMPP, but it fails with only the word 'Busy' in the Control Panel console. I ran xampp/install/portcheck.bat to see if the ports were available, and I see that port 3306 is busy (because I'm running MySQL as a service on it). I suppose that XAMPP wants to take over and run MySQL on that port. Can anyone tell me how to get XAMPP to just make use of the existing server and not try to control it itself?

  • Clustering with Vsphere and Apache load balacing

    - by Anonymous2011
    I was looking at Vsphere to automatically load balance my apache web servers, and mysql servers but will this actually do the job? I know it says it does auto load balancing but not actually sure it quite means what I want to achieve. Is there an easier way to set up a php-apache and mysql cluster within virtual machines? Or are there any guides to clustering? (I have tried googling without much luck) Any help towards understanding/setting up clustering and load balancing within virtual machines appreciated.

  • Strange Photoshop Problem: Can not select, zoom, paint, option button 'locked'

    - by nikcub
    I have a very strange problem with Photoshop. I can not use any of the tools, since the cursor appears 'locked'. If I select v on my keyboard, it goes to the zoom tool, but the cursor does not change. If I select the paintbrush tool, I can only paint if I hold down the option key. This is what the cursor look like (I had to paint it since I couldn't capture it). It is a rectangle with two lines through it. I am running Photoshop CS4 on a Macbook Pro with Mac OS X 10.6.6. Using both the trackpad and an external Logitech MX5000 mouse I see the same issue. This started when I fired up Photoshop today for the first time in a while. I can't remember changing any options or doing anything that could cause this. Is it possible that the option key is somehow locked in place, or there is some equivalent of num lock on? Very strange problem, I would appreciate any help anybody can offer. Edit: To add, the icon remains the same within all the menu options - it never goes back to being just a normal mouse cursor. Also, right click works fine, and if I hold down option, the cursor goes back to normal and I can paint with it. I can't use Marquee, Lasso, Crop, Type etc. even with option held down. When I go into Bridge, it is the same icon.

  • PHP and MySQL on IIS7: can't find php_mcrypt.dll in php.ini

    - by user46250
    I have installed PHP with Microsoft Web PI. Then I installed mysql. According to http://learn.iis.net/page.aspx/353/install-and-configure-mysql-for-php-applications-on-iis-7/ I have to Uncomment the following lines by removing the semicolon: extension=php_mysqli.dll extension=php_mbstring.dll extension=php_mcrypt.dll But there is no extension=php_mcrypt.dll in php.ini installed by web PI so should I add it by hand then where ? and where should I check that php_mcrypt.dll exists ? Seems nobody knows, should better ask on Microsoft forum ?

  • Can't access phpMyAdmin because of host, username and password

    - by Engprof
    everyone. When I try to access phpMyAdmin on Uniform Server I get the following error messages: " #1045 - Access denied for user 'root'@'localhost' (using password: YES) " " phpMyAdmin tried to connect to the MySQL server, and the server rejected the connection. You should check the host, username and password in your configuration and make sure that they correspond to the information given by the administrator of the MySQL server. " The funny thing is my username and password are both set to "root" and I have changed the IP address in the httpd.conf file to my Unique IP adddress, so I still don't know what the problem is. Could somebody please help me out? Any help would be much appreciated.

  • Is it safe to use up all memory on linux server, not leaving anything for the cache?

    - by Temnovit
    I have a CentOS server fully dedicated to MySQL 5.5 (with innodb tables mostly). Server has 32 GB RAM, SSD disks, and avarage memory usage looks like this: So about 25GB is in use and about 6.5GB is cached. I am experiencing performance problems with WRITE queries, so I was thinking, is this the optimal cache size? I might increase innodb buffer size, so that linux cache would become smaller, or decrease it, so it would be bigger. What is the optimal used/cached memory balance for busy MySQL server on linux?

  • Upgrading Fedora to Current Version - Dependent Applications Concerns

    - by nicorellius
    Is it possible to upgrade to Fedora 11 and still keep the server functional (it's running Fedora Core release 6 now, with MySQL 5.0, PHP 5.1 and Apache 2.2)? I have a Customer Relationship Management system on there and it is required on a daily basis. I am trying to figure out if I should upgrade (and whether that will cause huge problems) or if I should start over with a new OS (like Ubuntu) and install the CRM fresh, with updated version of MySQL, PHP, Apache, etc. I ask because I am not really the sysadmin, but have but put in charge of this server.

  • Access denied for user 'root@localhost' (using password:NO)

    - by murgatroid99
    I am attempting to install a network management package called cacti onto Ubuntu running under Windows Virtual PC. I attempted to install MySQL as it is one of cacti's dependencies. I can install and start the MySQL server, but whenever I try to access it in any other way, such as to change the password, I get the error message Access denied for user 'root@localhost' (using password:NO). I would like to know what is causing this and how to fix it. Edit: (just in case my comments are not visible) The answers from HD and Devin Ceartas did not work for me.

  • Should we regularly schedule mysqlcheck (or databsae optimization)

    - by scatteredbomb
    We run a forum with some 2 million posts and I've noticed that if left untouched the overhead in the mySQL (as listed in phpMyAdmin) can get quite large (hundreds of megabytes). I'm wondering if scheduling a normal mysqlcheck to optimize the tables is good practice? Any reason not to do it, say, once a week at an off-peak hour? There was a time over the summer where our site was constantly crashing because mysql was using up all resources. That's when I noticed the huge amount of overhead and optimized the database and haven't had any problems since then with stability. I figured if that was helping alleviate the issues, I should just setup a cron to automatically do this.

  • How to copy a file to a remote server using the command line?

    - by cool_cs
    I am trying to copy a file from my desktop to my remote server using the sudo command. I am doing this from the remote machine since I know the password for this machine and I do not have a password for my local machine. sudo scp donj@localhost:/Desktop/my.cnf user@remotemachine:/app/MySQL/my.cnf This does not work however. I want to overwrite the my.cnf file in the MySQL directory. I tried the su command but I do not have the password to become a super user.

  • IsNumeric() Broken? Only up to a point.

    - by Phil Factor
    In SQL Server, probably the best-known 'broken' function is poor ISNUMERIC() . The documentation says 'ISNUMERIC returns 1 when the input expression evaluates to a valid numeric data type; otherwise it returns 0. ISNUMERIC returns 1 for some characters that are not numbers, such as plus (+), minus (-), and valid currency symbols such as the dollar sign ($).'Although it will take numeric data types (No, I don't understand why either), its main use is supposed to be to test strings to make sure that you can convert them to whatever numeric datatype you are using (int, numeric, bigint, money, smallint, smallmoney, tinyint, float, decimal, or real). It wouldn't actually be of much use anyway, since each datatype has different rules. You actually need a RegEx to do a reasonably safe check. The other snag is that the IsNumeric() function  is a bit broken. SELECT ISNUMERIC(',')This cheerfully returns 1, since it believes that a comma is a currency symbol (not a thousands-separator) and you meant to say 0, in this strange currency.  However, SELECT ISNUMERIC(N'£')isn't recognized as currency.  '+' and  '-' is seen to be numeric, which is stretching it a bit. You'll see that what it allows isn't really broken except that it doesn't recognize Unicode currency symbols: It just tells you that one numeric type is likely to accept the string if you do an explicit conversion to it using the string. Both these work fine, so poor IsNumeric has to follow suit. SELECT  CAST('0E0' AS FLOAT)SELECT  CAST (',' AS MONEY) but it is harder to predict which data type will accept a '+' sign. SELECT  CAST ('+' AS money) --0.00SELECT  CAST ('+' AS INT)   --0SELECT  CAST ('+' AS numeric)/* Msg 8115, Level 16, State 6, Line 4 Arithmetic overflow error converting varchar to data type numeric.*/SELECT  CAST ('+' AS FLOAT)/*Msg 8114, Level 16, State 5, Line 5Error converting data type varchar to float.*/> So we can begin to say that the maybe IsNumeric isn't really broken, but is answering a silly question 'Is there some numeric datatype to which i can convert this string? Almost, but not quite. The bug is that it doesn't understand Unicode currency characters such as the euro or franc which are actually valid when used in the CAST function. (perhaps they're delaying fixing the euro bug just in case it isn't necessary).SELECT ISNUMERIC (N'?23.67') --0SELECT  CAST (N'?23.67' AS money) --23.67SELECT ISNUMERIC (N'£100.20') --1SELECT  CAST (N'£100.20' AS money) --100.20 Also the CAST function itself is quirky in that it cannot convert perfectly reasonable string-representations of integers into integersSELECT ISNUMERIC('200,000')       --1SELECT  CAST ('200,000' AS INT)   --0/*Msg 245, Level 16, State 1, Line 2Conversion failed when converting the varchar value '200,000' to data type int.*/  A more sensible question is 'Is this an integer or decimal number'. This cuts out a lot of the apparent quirkiness. We do this by the '+E0' trick. If we want to include floats in the check, we'll need to make it a bit more complicated. Here is a small test-rig. SELECT  PossibleNumber,         ISNUMERIC(CAST(PossibleNumber AS NVARCHAR(20)) + 'E+00') AS Hack,        ISNUMERIC (PossibleNumber + CASE WHEN PossibleNumber LIKE '%E%'                                          THEN '' ELSE 'E+00' END) AS Hackier,        ISNUMERIC(PossibleNumber) AS RawIsNumericFROM    (SELECT CAST(',' AS NVARCHAR(10)) AS PossibleNumber          UNION SELECT '£' UNION SELECT '.'         UNION SELECT '56' UNION SELECT '456.67890'         UNION SELECT '0E0' UNION SELECT '-'         UNION SELECT '-' UNION SELECT '.'         UNION  SELECT N'?' UNION SELECT N'¢'        UNION  SELECT N'?' UNION SELECT N'?34.56'         UNION SELECT '-345' UNION SELECT '3.332228E+09') AS examples Which gives the result ... PossibleNumber Hack Hackier RawIsNumeric-------------- ----------- ----------- ------------? 0 0 0- 0 0 1, 0 0 1. 0 0 1¢ 0 0 1£ 0 0 1? 0 0 0?34.56 0 0 00E0 0 1 13.332228E+09 0 1 1-345 1 1 1456.67890 1 1 156 1 1 1 I suspect that this is as far as you'll get before you abandon IsNumeric in favour of a regex. You can only get part of the way with the LIKE wildcards, because you cannot specify quantifiers. You'll need full-blown Regex strings like these ..[-+]?\b[0-9]+(\.[0-9]+)?\b #INT or REAL[-+]?\b[0-9]{1,3}\b #TINYINT[-+]?\b[0-9]{1,5}\b #SMALLINT.. but you'll get even these to fail to catch numbers out of range.So is IsNumeric() an out and out rogue function? Not really, I'd say, but then it would need a damned good lawyer.

  • Problem with date_select when using :discard option. (Rails)

    - by MikeH
    I'm using a date_select with the option :discard_year => true If a user selects a date in the date select, and then he comes back and returns the select to the prompt values of Month and Day, Rails automatically sets the select values to January 1. I know this is the intended functionality if a month is selected and a day is left blank, but that's not the case here. In my example, the user sets both the month and day back to the prompt. By Rails forcing January 1, I'm getting bad results. I've tried every parameter available in the api. :default = nil, :include_blank = true. None of those change the behavior I'm describing. I've isolated the root of the problem, which is this: Because I'm discarding the :year parameter, when the user tries to return the month and day to the prompt values, Rails doesn't see an empty prompt select. It perhaps sees a year selected with empty month and day, which it then sets to January 1. This is the case because the :discard_year parameter does in fact set a date in the database, it just removes it from the view. How can I code around this problem?

  • Jquery .Show() .Hide() not working as expected

    - by fizgig07
    I'm trying to use the show and hide to display a different set of select options when a certain report type is selected. I have a couple problems with this: The .show .hide only execute properly if I pass params, slow fast, in the the first result of my conditional statement. If I take out the params or pass params in both results, only one select shows and it never changes.. here's is the code that currently kind of works. if ($('#ReportType').val() == 'PbuseExport') { $('#PbuseServices').show('fast'); $('#ReportServiceDropdown').hide('fast'); } else { $('#PbuseServices').hide(); $('#ReportServiceDropdown').show(); } After i've used this control I am taken to a differnt page. When I use the control again, it reatins the original search values and repopulates the control. Then again I only want to show one select option if a certain report is chosen.. This works correctly if the report type I originally searched on is not the "PbuseExport". If I searched on the report type "PbuseExport", then both selects show on the screen, and only until I change the report type does it show only one select. I know this probably isn't very clear.. Here is the code that handles the change event on the report type drop down. var serviceValue = $("#ReportType").val(); switch (serviceValue) { case 'PbuseExport': $('#PbuseServices').show('fast'); $('#ReportServiceDropdown').hide('fast'); default: $('#PbuseServices').hide(); $('#ReportServiceDropdown').show(); break; }

  • Opera bug with JS autoselecting text (if more than 1 div)

    Here is HTML code. It supposed to select all text in "Container" div <B onclick="SelectText(document.getElementById('Container'));">select all text</B> <Div id="Container"> <Div>123456</Div> <Div>123456</Div> <Div onclick="SelectText();">123456</Div> </Div> here is JS code of the SelectText() function function SelectText(target){ if(target==null){ var e = window.event || e; if (!e) var e = window.event; var target=e.target || e.srcElement; } var rng, sel; if ( document.createRange ) { rng = document.createRange(); rng.selectNode( target ); sel = window.getSelection(); sel.removeAllRanges(); sel.addRange( rng ); } else { var rng = document.body.createTextRange(); rng.moveToElementText( target ); rng.select(); } } Problem is that in Opera 12.02 when "select all text" is clicked, all text seems like selected, but it's not selected (I can't rightclick it and copy). (terrific, but IE works fine with it) Why not in Opera?!!! And what can I do to make Opera 12.02 believe that all text in "Container" is selected?

  • Using xsl:variable in a xsl:foreach select statment

    - by Nefariousity
    I'm trying to iterate through an xml document using xsl:foreach but I need the select=" " to be dynamic so I'm using a variable as the source. Here's what I've tried: ... <xsl:template name="SetDataPath"> <xsl:param name="Type" /> <xsl:variable name="Path_1">/Rating/Path1/*</xsl:variable> <xsl:variable name="Path_2">/Rating/Path2/*</xsl:variable> <xsl:if test="$Type='1'"> <xsl:value-of select="$Path_1"/> </xsl:if> <xsl:if test="$Type='2'"> <xsl:value-of select="$Path_2"/> </xsl:if> <xsl:template> ... <!-- Set Data Path according to Type --> <xsl:variable name="DataPath"> <xsl:call-template name="SetDataPath"> <xsl:with-param name="Type" select="/Rating/Type" /> </xsl:call-template> </xsl:variable> ... <xsl:for-each select="$DataPath"> ... The foreach threw an error stating: "XslTransformException - To use a result tree fragment in a path expression, first convert it to a node-set using the msxsl:node-set() function." When I use the msxsl:node-set() function though, my results are blank. I'm aware that I'm setting $DataPath to a string, but shouldn't the node-set() function be creating a node set from it? Am I missing something? When I don't use a variable: <xsl:for-each select="/Rating/Path1/*"> I get the proper results. Here's the XML data file I'm using: <Rating> <Type>1</Type> <Path1> <sarah> <dob>1-3-86</dob> <user>Sarah</user> </sarah> <joe> <dob>11-12-85</dob> <user>Joe</user> </joe> </Path1> <Path2> <jeff> <dob>11-3-84</dob> <user>Jeff</user> </jeff> <shawn> <dob>3-5-81</dob> <user>Shawn</user> </shawn> </Path2> </Rating> My question is simple, how do you run a foreach on 2 different paths?
