  • Center <div> vertically within another <div>

    - by sab
    I am trying to setup something that looks like this with the arrow that is centered vertically: CSS: #arrowdiv { width:282px; height:61px; background-image:url('http://i.imgur.com/RV80I.png'); margin: 0 auto; } #optin { height:110px; width:960px; background-color:#FFFFBF; border:1px solid black; -moz-border-radius: 15px; border-radius: 15px; -moz-box-shadow: 3px 3px 4px #000; -webkit-box-shadow: 3px 3px 4px #000; box-shadow: 3px 3px 4px #000; /* For IE 8 */ -ms-filter: "progid:DXImageTransform.Microsoft.Shadow(Strength=4, Direction=135, Color='#000000')"; /* For IE 5.5 - 7 */ filter: progid:DXImageTransform.Microsoft.Shadow(Strength=4, Direction=135, Color='#000000'); margin: 0 auto; } #leftdiv { width:340px; height:108px; } ? HTML: <div id="optin"> <div id="leftdiv"> <div id="arrowdiv"></div> </div> </div>? http://jsfiddle.net/NzMLd/1/ Right now, it is only centered horizontally, as you can see in my jsFiddle.

  • Cannot locate record in delphi ADO query

    - by Danatela
    I can't locate any record in TADOQuery using PK. First, I was trying to use standard Locate method: PPUQuery.Locate('ID', SpPlansQuery['PPONREC'], []); It always returns False, but manual search (passing the whole query matching ID with given PPONREC which is really slow) finds the desired row. I tried using loPartialKey and switched CursorLocation of query to clUseServer, but it didn't help. Next, I tried to filter my PPUQuery: PPUQuery.Filter := 'ID = ' + VarToStr(SpPlansQuery['PPONREC']); PPUQuery.Filtered := True; PPUQuery.First; But after that the PPUQuery.Eof is True and PPUQuery.RecordCount equals 0. Underlying database is Oracle 9 and the ID is of type INTEGER and is PK of table TPORDER_CMK. PPUQuery.SQL is: SELECT tp.*, la.*, lm.*, ld.*, ld1.*, to_cmk.* FROM ppu_plan.tporder_cmk tp JOIN PPU_PLAN.LARTICLES la ON TP.ARTICLE = LA.ID JOIN PPU_PLAN.LMATERIAL lm ON TP.MATERIAL = lm.id JOIN PPU_PLAN.LCADEP ld ON TP.CADEP = LD.ID JOIN PPU_PLAN.LCADEP ld1 ON TP.PRODUCER = LD1.ID JOIN PPU_PLAN.TORDER_CMK to_cmk ON TP.order_id=TO_cmk.ID WHERE TP.PLAN_ID = :pplan_id What should I try next and how to solve this problem?

  • Speeding up a group by date query on a big table in postgres

    - by zaius
    I've got a table with around 20 million rows. For arguments sake, lets say there are two columns in the table - an id and a timestamp. I'm trying to get a count of the number of items per day. Here's what I have at the moment. SELECT DATE(timestamp) AS day, COUNT(*) FROM actions WHERE DATE(timestamp) >= '20100101' AND DATE(timestamp) < '20110101' GROUP BY day; Without any indices, this takes about a 30s to run on my machine. Here's the explain analyze output: GroupAggregate (cost=675462.78..676813.42 rows=46532 width=8) (actual time=24467.404..32417.643 rows=346 loops=1) -> Sort (cost=675462.78..675680.34 rows=87021 width=8) (actual time=24466.730..29071.438 rows=17321121 loops=1) Sort Key: (date("timestamp")) Sort Method: external merge Disk: 372496kB -> Seq Scan on actions (cost=0.00..667133.11 rows=87021 width=8) (actual time=1.981..12368.186 rows=17321121 loops=1) Filter: ((date("timestamp") >= '2010-01-01'::date) AND (date("timestamp") < '2011-01-01'::date)) Total runtime: 32447.762 ms Since I'm seeing a sequential scan, I tried to index on the date aggregate CREATE INDEX ON actions (DATE(timestamp)); Which cuts the speed by about 50%. HashAggregate (cost=796710.64..796716.19 rows=370 width=8) (actual time=17038.503..17038.590 rows=346 loops=1) -> Seq Scan on actions (cost=0.00..710202.27 rows=17301674 width=8) (actual time=1.745..12080.877 rows=17321121 loops=1) Filter: ((date("timestamp") >= '2010-01-01'::date) AND (date("timestamp") < '2011-01-01'::date)) Total runtime: 17038.663 ms I'm new to this whole query-optimization business, and I have no idea what to do next. Any clues how I could get this query running faster?

  • Multiple collections tied to one base collection with filters and eventing

    - by damienc88
    I have a complex model served from my back end, which has a bunch of regular attributes, some nested models, and a couple of collections. My page has two tables, one for invalid items, and one for valid items. The items in question are from one of the nested collections. Let's call it baseModel.documentCollection, implementing DocumentsCollection. I don't want any filtration code in my Marionette.CompositeViews, so what I've done is the following (note, duplicated for the 'valid' case): var invalidDocsCollection = new DocumentsCollection( baseModel.documentCollection.filter(function(item) { return !item.isValidItem(); }) ); var invalidTableView = new BookIn.PendingBookInRequestItemsCollectionView({ collection: app.collections.invalidDocsCollection }); layout.invalidDocsRegion.show(invalidTableView); This is fine for actually populating two tables independently, from one base collection. But I'm not getting the whole event pipeline down to the base collection, obviously. This means when a document's validity is changed, there's no neat way of it shifting to the other collection, therefore the other view. What I'm after is a nice way of having a base collection that I can have filter collections sit on top of. Any suggestions?

    I m trying to start an IntentService from the main activity of y application and it won't start. I have the service in the manifest file.

  • CSS div and image opacity effect

    - by user1704514
    The following code shows the image in the div tag. <div class='item'> <img class='img' src="image1.png" alt="" /> </div> I am using the following css to add effects to the html image code: img{ width:50px; height:50px; opacity:0.4; filter:alpha(opacity=40); } img:hover{ opacity:1.0; filter:alpha(opacity=100); } I am using this to have opacity effects in css. With this code, the opacity effect works well when I hover over the image itself. But how do I make it so that the opacity effect on the image occurs when I hover over the div tag instead. I want to be able to hover over any part of the item div which encapsulated the image, to get the change opacity effect on the image. NB effect on just the image not the entire div. Can this be done in css? If so how?

  • F# why my recursion is faster than Seq.exists?

    I am pretty new to F#. I'm trying to understand how I can get a fast code in F#. For this, I tried to write two methods (IsPrime1 and IsPrime2) for benchmarking. My code is: // Learn more about F# at http://fsharp.net open System open System.Diagnostics #light let isDivisible n d = n % d = 0 let IsPrime1 n = Array.init (n-2) ((+) 2) |> Array.exists (isDivisible n) |> not let rec hasDivisor n d = match d with | x when x < n -> (n % x = 0) || (hasDivisor n (d+1)) | _ -> false let IsPrime2 n = hasDivisor n 2 |> not let SumOfPrimes max = [|2..max|] |> Array.filter IsPrime1 |> Array.sum let maxVal = 20000 let s = new Stopwatch() s.Start() let valOfSum = SumOfPrimes maxVal s.Stop() Console.WriteLine valOfSum Console.WriteLine("IsPrime1: {0}", s.ElapsedMilliseconds) ////////////////////////////////// s.Reset() s.Start() let SumOfPrimes2 max = [|2..max|] |> Array.filter IsPrime2 |> Array.sum let valOfSum2 = SumOfPrimes2 maxVal s.Stop() Console.WriteLine valOfSum2 Console.WriteLine("IsPrime2: {0}", s.ElapsedMilliseconds) Console.ReadKey() IsPrime1 takes 760 ms while IsPrime2 takes 260ms for the same result. What's going on here and how I can make my code even faster?

  • Getting a Script Error Every Time I Click a Link

    - by Flip4Life
    I have everything working perfectly on my site, but for some reason, I get an error message in console whenever I click a link anywhere on my site. The error has to do with this line of coding here: jQuery(function($){ $('.navbar a, .scroll a, .smoothscroll a').bind('click',function(event){ var $anchor = $(this); $('html, body').stop().animate({ scrollTop: $($anchor.attr('href')).offset().top }, 850,'easeInOutExpo'); event.preventDefault(); }); }); And the error I am getting is this: "SCRIPT5007: Unable to get value of the property 'top': object is null or undefined custom.min.js, line 6 character 197" The exact code it is highlighting is this part of the above code: $('html, body').stop().animate({ scrollTop: $($anchor.attr('href')).offset().top }, 850,'easeInOutExpo') All I know is that when I remove the above code, my scroll-to links stop working on pages such as these: http://www.northtownsremodeling.com/things-to-know.php You can see the popup error happen and stay in the console easily by going to a page with a filter like this: http://www.northtownsremodeling.com/bathroom/ And clicking one of the filter buttons. Ultimately, I am trying to make it so my scroll-to setting still works, but not have that error come up anymore. I made this script a long time ago, and I'm really confused as to what could be causing this error when everything is functioning perfectly otherwise? Thanks!

  • How do I remove unnecessary options from a select field in a Drupal form?

    - by thismax
    I'm using the better_exposed_filters module to create a set of exposed filters for a view. One of the filters is being displayed as a select field, and I would like the field to only display options that are actually associated with content in the database. Currently, I am doing this using the hook_form_alter() method. For simplification, in the following example the field is called 'foo' and the content type with that field is called 'bar': function my_module_form_alter(&$form, $form_state, $form_id) { // Get all the values of foo that matter $resource = db_query('select distinct field_foo_value from {content_type_bar}'); $foo = array(); while($row = db_fetch_object($resource)) { $foo[$row->field_foo_value] = $row->field_foo_value; } $form['foo']['#options'] = $manufacturers; } This works great -- the form displays only the options I want to display. Unfortunately, the view doesn't actually display anything initially and I also get the following error message: An illegal choice has been detected. Please contact the site administrator. After I filter options with the form once, everything seems to work fine. Does anyone know how I can solve this problem? I'm open to an entirely different way of weeding out filter options, if need be, or a way that I can figure out how to address that error.

  • resultCode is always 0

    I'm trying to get the resultCode to be OK inside my onActivityResult function. However, it keeps coming back as 0. I have spent several days on this, and can't figure out why it doesn't work. Here's my code. If anybody can help me, I'll be very grateful, Thanks. My Activity1 class: private class MyTask extends AsyncTask<String, Void, String> { @Override protected String doInBackground(String... urls) { // process return result; } @Override protected void onPostExecute(String result) { Intent i = new Intent(Activity1.this, Activity2.class); i.putExtra("Value1", "This value one for ActivityOne "); i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivityForResult(i, REQUEST_CODE); textView.setText(result); } } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (resultCode == RESULT_OK && requestCode == REQUEST_CODE) { // do something } } My Activity 2 class: @Override public void finish() { Intent data = new Intent(); data.putExtra("returnKey1", "return 1"); setResult(RESULT_OK, data); super.finish(); } My manifest: <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".Activity1" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name=".Activity2" android:label="@string/app_dialog_name" android:launchMode="singleTop" android:excludeFromRecents="true" android:taskAffinity="" android:theme="@android:style/Theme.Dialog"> </activity> </application>

  • Strange permission errors in new PostgreSQL installation

    - by Bart van Heukelom
    A freshly installed PostgreSQL (with configuration overwritten) won't start: $ sudo service postgresql start * Starting PostgreSQL 9.1 database server * Error: could not read /etc/postgresql/9.1/main/postgresql.conf: Permission denied Looks like it should be able to read it though: $ ls -l postgresql.conf -rw------- 1 postgres postgres 19450 2012-06-14 10:07 postgresql.conf But fine, I'll add chmod +r it to test if that works. $ sudo chmod +r postgresql.conf $ sudo service postgresql start * Starting PostgreSQL 9.1 database server * The PostgreSQL server failed to start. Please check the log output: Error: Could not open log file /var/log/postgresql/postgresql-9.1-main.log Huh? $ ls -l /var/log/postgresql/ total 4 -rw-r----- 1 postgres adm 827 2012-06-14 10:07 postgresql-9.1-main.log I don't get it. What can be wrong here? This used to work before. Can I maybe monitor what process attempts to open the file? It's Ubuntu 11.10 on EC2, using Chef. For completeness, here's the recipe: # Install PostgreSQL package "postgresql-9.1" # Stop server service "postgresql" do action :stop end # Overwrite configuration (setting data dir) template "/etc/postgresql/9.1/main/postgresql.conf" do source "postgresql-conf.erb" owner "postgres" group "postgres" end # Start server service "postgresql" do action :start end

  • Windows Backup failed as another backup or recovery is in progress.

    - by remunda
    Hi, i have set up backup schedule on our server. SQL Server 2008 to 01:00am on windows server 2008 R2 to 4:00am. Sql backup runs well, but system backup ends sometimes with error. The error is : http://technet.microsoft.com/en-us/library/dd364768%28WS.10%29.aspx I mean, that is caused by SQL Server, because it unexpectedly runs backup. this is from sql server log (it runs for every database): Date 4.2.2010 4:00:21 Log SQL Server (Current - 29.1.2010 23:25:00) Source spid72 Message I/O is frozen on database master. No user action is required. However, if I/O is not resumed promptly, you could cancel the backup. and Date 4.2.2010 4:00:24 Log SQL Server (Current - 29.1.2010 23:25:00) Source Backup Message Database backed up. Database: master, creation date(time): 2010/01/29(23:25:32), pages dumped: 370, first LSN: 859:56:37, last LSN: 859:80:1, number of dump devices: 1, device information: (FILE=1, TYPE=VIRTUAL_DEVICE: {'{17B91D5C-9968-4D11-A7F1-1A31523D32F0}25'}).

  • Synergy Key Mapping

    - by Tauren
    I'm running a Synergy server on Ubuntu and a Synergy+ client on OSX. The server has a standard windows keyboard with shift, ctrl, windows, and alt keys. My MacBookPro has shift, fn, control, alt/option, and command keys. When I press ctrl-c, ctrl-v, etc, the appropriate copy/paste action doesn't happen on the Mac, but it does in Ubuntu. If I'm controlling the mac, and press alt-c, alt-v, then I get the copy/paste action. So I played around with key mapping in synergy.conf and found that the following allows me to do copy/paste with ctrl-c/ctrl-v: section: screens godzilla: mbp.local: ctrl = alt alt = ctrl end Is this all that I need to do? Or are there other mappings that will help as well? The synergy configuration page refers to the following key mappings. What are the equivalent keys for each of these on the Windows keyboard and Mac keyboard? What is a meta or super key? shift = {shift|ctrl|alt|meta|super|none} ctrl = {shift|ctrl|alt|meta|super|none} alt = {shift|ctrl|alt|meta|super|none} meta = {shift|ctrl|alt|meta|super|none} super = {shift|ctrl|alt|meta|super|none} Thanks!

  • Adding an user to samba

    - by JustMaximumPower
    I'm trying to setup some samba shares in my home network on an Ubuntu 12.04 machine. Everything works fine for my user account (max) but I can not add any new user. Every time I try to add new user they can not use the shares. It's likely that the error is very basic to the concept of samba but please don't just tell me to read the docs. I've been trying that for about 2 weeks now. I've set up the server with my user max who can mount transfer and the share max. Than I added the user simon with sudo adduser --no-create-home --disabled-login --shell /bin/false simon because the user should not be able to ssh into the machine. I did an sudo smbpasswd -a simon and set an (samba) password for simon and added an share for simon. I also added simon to transferusers to give him access to the share transfer. But simon can't connect to transfer or simons. ---- output of testparam: ------- Load smb config files from /etc/samba/smb.conf rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384) Processing section "[printers]" Processing section "[print$]" Processing section "[max]" Processing section "[simons]" Processing section "[transfer]" Loaded services file OK.

  • Moving from WDS to MDT + WDS - Prestaged Computer Name

    - by MSCF
    We previously used just WDS to deploy our images. WDS was setup to request approval for new machines. We used the "Name and Approve" option to name the machines as we added them. If it was pre-existing, it would just use the existing computer name from AD. Then in our unattend.xml file we had Computername=%MACHINENAME%. This picked up the name we gave it during approval and set the computer name accordingly. We are now implementing MDT to manage our images and drivers. But upon testing, we noticed it would assign random computer names. I went into the Unattend.xml for the deploy task sequence and added that value under Specialize amd64_Microsoft-Windows-Shell-Setup_neutral Computername=%MACHINENAME%. But when we try applying the image, it errors out at that point of the install. How can an MDT deployment be configured to leverage the pre-staged name? Some additional info: Error message during the imaging process: Windows could not parse or process the unattend answer file for pass [specialize]. The settings specified in the answer file cannot be applied. The error was detected while processing settings for component [Microsoft-Windows-Shell-Setup].? setuperr.log: 2014-07-22 14:02:13, Error [setup.exe] [Action Queue] : Unattend action failed with exit code 4 2014-07-22 14:02:13, Error [setup.exe] Execution of unattend GCs failed; hr = 0x0; pResults-hrResult = 0x8030000b

  • Problem with MS DTC on SQL2008 win server 2k8 with linked server from sql2000 win server 2k

    - by user31648
    Hi, We have migrated our db from sql2000 win server 2k to sql2008 win server 2k8. We have linked server from sql2000 win server 2k. By our opinion the problem is with DTC and we have made a lot of setting that we found as solution for our problem, but still the problem exist. There is no any error or worning or information niether in the sql log nor in win event viewer. The application is hanging out and at the end the time out exception is shown. What we have done till now: Enable Network DTC Access with inbound and outbound with No Authentication Required on win 2k8 We have opened RPC dynamic port allocation through registry on 2k and 2k8 We have entered subkey TurnOffRpcSecurity in the registry HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSDTC and made it enable on 2k and 2k8 We have added exception for DTC in firewall for all entities What we have notice that when we restart SQL service and make the first try for our transaction the following is shown: "Attempting to initialize Microsoft Distributed Transaction Coordinator (MS DTC). This is an informational message only. No user action is required." and after it: "Recovery of any in-doubt distributed transactions involving Microsoft Distributed Transaction Coordinator (MS DTC) has completed. This is an informational message only. No user action is required." Does someone have any idea what else can be done in order to solve the problem? Thanks in advance. Regards, Snezana

  • How to do 'search for keyword in files' in emacs in Windows without cygwin?

    I want to search for keyword, says 'action', in a bunch of files in my Windows PC with Emacs. It is partly because I want to learn more advanced features of emacs. It is also because the Windows PC is locked down by company policy. I cannot install useful applications like cygwin at will.

  • Ingress filtering in Linux traffic control: Redirect traffic to IFB device

    - by Dani Camps
    I have an openwrt router and I want to shape incoming traffic in order to classify all the traffic addressed to a certain IP address in my home network as low priority. For that purpose I want to redirect all traffic incoming to the eth1 interface, the one connected to the DSL modem, to an IFB device where I will do the shaping. These are the details of my system: Linux OpenWrt 2.6.32.27 #7 Fri Jul 15 02:43:34 CEST 2011 mips GNU/Linux Here is the script I am using where the last instruction is failing: # Variable definition ETH=eth1 IFB=ifb1 IP_LP="192.168.1.22/32" DL_RATE="900kbps" HP_RATE="890kbps" LP_RATE="10kbps" TC="tc" # Configuring the ifbX interface insmod ifb insmod sch_htb insmod sch_ingress ifconfig $IFB up # Adding the HTB scheduler to the ingress interface $TC qdisc add dev $IFB root handle 1: htb default 11 # Set the maximum bandwidth that each priority class can get, and the maximum borrowing they can do $TC class add dev $IFB parent 1:1 classid 1:10 htb rate $LP_RATE ceil $DL_RATE $TC class add dev $IFB parent 1:1 classid 1:11 htb rate $HP_RATE ceil $DL_RATE # Redirect all ingress traffic arriving at $ETH to $IFB $TC qdisc del dev $ETH ingress 2>/dev/null $TC qdisc add dev $ETH ingress $TC filter add dev $ETH parent ffff: protocol ip prio 1 u32 \ match u32 0 0 flowid 1:1 \ action mirred egress redirect dev $IFB The last instruction fails with: Action 4 device ifb1 ifindex 9 RTNETLINK answers: No such file or directory We have an error talking to the kernel Does anyone know what am I doing wrong ?

    - by Kedare
    I would like to know if there is not Fortigates an equivalent of the packet-tracer command that we can find on the ASA. Here is an example of execution for those who don't know it: NAT and pass : lev5505# packet-tracer input inside tcp 192.168.3.20 9876 8.8.8.8 80 Phase: 1 Type: ACCESS-LIST Subtype: Result: ALLOW Config: Implicit Rule Additional Information: MAC Access list Phase: 2 Type: ROUTE-LOOKUP Subtype: input Result: ALLOW Config: Additional Information: in 0.0.0.0 0.0.0.0 outside Phase: 3 Type: ACCESS-LIST Subtype: log Result: ALLOW Config: access-group inside-in in interface inside access-list inside-in extended permit tcp any any eq www access-list inside-in remark Allows DNS Additional Information: Phase: 4 Type: IP-OPTIONS Subtype: Result: ALLOW Config: Additional Information: Phase: 5 Type: VPN Subtype: ipsec-tunnel-flow Result: ALLOW Config: Additional Information: Phase: 6 Type: NAT Subtype: Result: ALLOW Config: object network inside-network nat (inside,outside) dynamic interface Additional Information: Dynamic translate 192.168.3.20/9876 to 81.56.15.183/9876 Phase: 7 Type: IP-OPTIONS Subtype: Result: ALLOW Config: Additional Information: Phase: 8 Type: FLOW-CREATION Subtype: Result: ALLOW Config: Additional Information: New flow created with id 94755, packet dispatched to next module Result: input-interface: inside input-status: up input-line-status: up output-interface: outside output-status: up output-line-status: up Action: allow Blocked by ACL: lev5505# packet-tracer input inside tcp 192.168.3.20 9876 8.8.8.8 81 Phase: 1 Type: ROUTE-LOOKUP Subtype: input Result: ALLOW Config: Additional Information: in 0.0.0.0 0.0.0.0 outside Phase: 2 Type: ACCESS-LIST Subtype: Result: DROP Config: Implicit Rule Additional Information: Result: input-interface: inside input-status: up input-line-status: up output-interface: outside output-status: up output-line-status: up Action: drop Drop-reason: (acl-drop) Flow is denied by configured rule Is there any equivalent on the Fortigates ?

  • Netscaler - Involving Response Body Replacement with GeoIP Implementation

    - by MrGoodbyte
    I have a Netscaler (10000) NS9.3: Build 52.3.cl There is a document contains a short tutorial about GeoIP database implementation at http://support.citrix.com/article/CTX130701 I have added location database by following this tutorial successfully but instead of dropping connections I need to replace a string in content body. To do that, I created a rewrite action with those parameters. * Name: ns_country_replacement_action * Type: REPLACE_ALL * Target Expression: HTTP.RES.BODY(50000) * Replacement Text: HTTP.RES.HEADER("international") * Pattern: \{\/\*COUNTRY_NAME\*\/\} To insert header called "international", I try to create another rewrite action with those parameters. I'll add this one's policy prior. * Name: ns_country_injection_action * Type: INSERT_HTTP_HEADER * Header Name: international * Header Value: CLIENT.IP.SRC.MATCHES_LOCATION("*.US.*.*.*.*").NOT When I click on create button, it says; Compound expression syntax error, [.*.*").NOT^, 50] I'm not sure but I think that two things might cause this error. The expression I use for MATCHES_LOCATION is wrong but I use same expression in the tutorial. MATCHES_LOCATION().NOT returns BOOLEAN but the field expects STRING. How can I get this work? Do I use right tools to accomplish what I need to do? Thank you. -Umut

  • multiple php compiler on single apache installation

    - by getmizanur
    elloo, i have some old php scripts which runs on php-5.2.x and the current server has php-5.3.x. to get around this problem,i have got two options one is to downgrade php-5.3.x or install php-5.2.x and php-5.3.x at the same time where php-5.2.x serve cgi script. i have decided go for the second option i have followed this tutorial and i can get most of it working however except execution of shell script which selects php-cgi version. i cannot get apache to execute this script. how do i get apache to execute #!/bin/sh # you can change the PHP version here. version="5.2.6" # php.ini file location, */php-5.2.6/lib equals */php-5.2.6/lib/php.ini. PHPRC=/etc/php/phpfarm/inst/php-${version}/lib/php.ini export PHPRC PHP_FCGI_CHILDREN=3 export PHP_FCGI_CHILDREN PHP_FCGI_MAX_REQUESTS=5000 export PHP_FCGI_MAX_REQUESTS # which php-cgi binary to execute exec /etc/php/phpfarm/inst/php-${version}/bin/php-cgi my apache vhost.conf <VirtualHost *:80> ServerName 526.localhost DocumentRoot /home/getmizanur/public_html/www <Directory "/home/getmizanur/public_html/www"> AddHandler php-cgi .php Action php-cgi /php-fcgi/php-cgi-5.2.6 </Directory> </VirtualHost> can some one tell me what am i doing wrong? thanks in advance. solution: if i did a2dismod php5 then the above configuration worked. when a2enmod php5 had been activated, apache was executing php5.3 instead of php5.2 even after telling apache to execute php5.2 shell script. to solve my problem, i had to change my virtualhost configuration <VirtualHost *:80> ServerName 526.localhost DocumentRoot /home/getmizanur/public_html/www DirectoryIndex index.php <Directory "/home/getmizanur/public_html/www"> AddHandler php-cgi .php Action php-cgi /php-fcgi/php-cgi-5.2.6 <FilesMatch "\.php"> SetHandler php-cgi </FilesMatch> </Directory> </VirtualHost> presto, it started working.

  • Java Deployment Ruleset not working

    - by adbertram
    I've created a Java Deployment Ruleset that looks like this: <ruleset version="1.0+"> <rule> <id location="http://hpfweb.mydomain.com/" /> <action permission="run" version="1.6.0_20" /> </rule> <rule> <id location="http://*.mydomain.com" /> <action permission="run" /> </rule> <rule> </ruleset> I've created a self-signed cert, added it into the keystore as well as Trusted Certification Authorities. I have an app at http://hpfweb.mydomain.com that requires Java v1.6.20 and will error out if any other version is attempted. When only this version is installed on the computer the application works. However, if a newer version is installed, it does not. As you can see, I've attempted to force the version to 1.6.0_20 in the ruleset. I've confirmed the deployment rule set is being applied successfully by going into the Java Control Panel -- Security and "view the active deployment rule set". It is exactly as you see here. I've also looked at the web source for the application and all references point to http://hpfweb* links. When the applet is launched I've brought up task manager and have confirmed the java.exe launched is coming from the jre6 directory. When the newer version is installed, I'm getting the error "accesscontrolexception - access denied (java.awt.AWTPermission.accessEventQueue".
