I am running a monitoring site developed in yii framework using xampp on a windows server machine to check the health of databases. Normally everything works fine but sometimes it gives me the following error:
Code: 12545|Message: CDbConnection failed to open the DB connection: SQLSTATE[HY000]: pdo_oci_handle_factory: ORA-12545: Connect failed because target host or object does not exist (ext\pdo_oci\oci_driver.c:635)
I check ping and everything is fine, tns_ping is working, other users can logon to database and use it. but i get the above error.
PHP Version 5.5.28
Oracle9i Enterprise Edition Release 9.2.0.8.0 - 64bit Production
Oracle Instant Client - 11.2.0.1.0
Windows Server 2012 R2 Standard
PDO Driver for OCI 8 and later enabled
Query used to check if we can connect to database and query it
select count(*) from dual
any help will be appreciated
I assume you are using yii 1 but nevertheless you should try those steps in fixing the error:
In most cases defining the database in your main.php fixes the problem, so try adding: 'connectionString'=>'oci:dbname=mydb',
Disable those extensions: php_pdo_oci8.dll and php_oci8.dll in your php.ini file and leave only the needed one for your environment: php_pdo_oci.dll.
Definitely update your Oracle to 10 or above because according to my experience and some internet forums Oracle client 9 can make some troubles with php 5.1 or above. Not in every scenario but I think it's worth the update.

As a young developer, my first task is to migrate a website on another server. I was thinking it will take me less than 2 days but no.
The website was made with PHP 5.6 with the CMS Joomla! 1.5. I've migrate the sources, but when I try the page, I got the message:
Database Error: Unable to connect to the database:Could not connect to MySQL
I've tried multiples manipulations:
I have installed Plesk Onyx for do the migration, but same message
I have tried with Plesk 12.5, but same,
I have tried by copiing sources manually on the serv, it didn't work too
I have check my LAMP server, the php test is okey, the mysql (MariaDB) too, and Apache2 test is okey.
I have already edit the configuration.php file, but it's the same problem.
I have tested on another OS for my server (last one was Debian), now I have installed centos 7, but I don't change anything.
Don't know what's wrong with my migration, if somebody have and idea, I'm listening
The answer is in the error message Joomla gave you. The details you've set for accessing the database are wrong.
Did you create a MySQL database for your new site? Did you import the database from the old site to the new server?
I got a PHP project which uses Medoo for accessing a database on MS SQL Server 2012. I used to test my project on the same server, but since copy-pasting through remote desktop got kinda annoying and inefficient, I wanted to move on a local system, so I installed Xampp (with PHP 5.6.19 VC11). Since I still need to use the server database, I first encountered the problem that the PDO MSSQL extension is not available anymore, and my script failed to send a query to the database. So tried using the SQLSRV 3.0 extension instead (5.4 thread-safe - why isn't there a version 5.6? Is 5.4 supposed to be forward compatible?), which still sends me an uncaught exception with message 'could not find driver', thrown from the PDO constructor and forwarded through Medoo. I'm not sure if this fails on Medoo, the driver, or something else. Moving the database to phpMyAdmin is no option... Has anyone an idea how I can solve this?
All information you need are on this this web page https://msdn.microsoft.com/en-us/library/cc296170(v=sql.105).aspx.
As you can see you need version 3.2 for PHP 5.6 support. I found download link and information about adding SQLSRV extension to php.ini for you.
https://www.microsoft.com/en-us/download/details.aspx?id=20098
https://msdn.microsoft.com/en-us/library/cc296203(v=sql.105).aspx
Finally you have to install Microsoft ODBC Driver 11 for SQL Server.
In short, download SQLSRV 3.2, add PDO extension to php.ini (choose right version for your PHP), install Microsoft ODBC Driver 11 for SQL Server on your local enviroment.
I am trying to get PHP with the SQL Server driver working under IIS. I had a similar situation 18 months ago with lesser versions of the php and the driver and Apache, and that code worked fine working on Windows Server 2003.
I am trying to set it up on my Windows 7 (Home Premium) Virtual Machine to work out how to do it, before attempting to get the same done on a Windows Server 2011.
Now I am coming to try the same code again and reset up my development environment. This time I am using PHP 5.5 and have installed the threadsafe version version of the driver php_pdo_sqlsrv_55_ts.dll obtained from the downloadable SQLSERVER31.exe file.
Doing all of this in 32 bit mode
As soon as I try and construct a new PDO I get the following error message
SQLSTATE[IMSSP]: This extension requires the ODBC Driver 11 for SQL
Server to communicate with SQL Server. Access the following URL to
download the ODBC Driver 11 for SQL Server for x86:
http://go.microsoft.com/fwlink/?LinkId=163712
So although that link isn't directly to the driver, I eventually find my way there and download it, only for it to fail to install. However, I think that might be because I already have the ODBC Driver 11 for SQL Server installed.
So according to my Data Sources (ODBC) application in the Administrative Tools Section there are two SQL Server ODBC drivers
SQL Server, verion 6.01.7602.17514 SQLSRV32.DLL Dated 21/11/2010
SQL Server Native Client 11, version 2011.110.5058.00 SQLNCLI11.DLL Dated 15/05/2014
So I really don't know how to go from here.
Can I remove a driver and re-install it. If so how?
Any other suggestions as to how to get this to work.
I discovered the answer to my problem. I hadn't installed the odbc driver - the drivers listed above are not the correct ones.
The reason the ODBC driver I downloaded failed to install wasn't because the driver was already installed - it was because I had downloaded the 32 bit version, and it HAS to be the 64 bit version.
As soon as I installed the 64 bit version, another entry appeared in the Data Sources Driver list, and my test program started to work
I am trying to access an SQL Server.
UPDATE: In response to Clive's comments below I have also tried reinstalling the native ODBC driver but no change.
I've checked over all the questions I can find on this and everything seems to be in order. My server details:
PHP 5.4 (Managed via Plesk)
SQL Server 2008 R2 SP2
Windows Server 2008 R2
The latest mssql drivers for PDO are in the EXT directory and referenced in php.ini:
extension=php_sqlsrv_54_nts.dll
extension=php_pdo_sqlsrv_54_nts.dll
PHPINFO() gives the following:
PDO Drivers: mysql, sqlite, sqlsrv
pdo_sqlsrv support: enabled
sqlsrv support: enabled
My connection string looks like this:
$DSN = "sqlsrv:Server=myDbServer,1433;database=my-dbname";
$PdoOptions = array(
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC
);
$sparklyGenericPdoObj = new PDO($DSN,'myUsername','myPasswurde', $PdoOptions);
But that just gives me the following error which links - in a roundabout way - to the drivers I already have installed (I've checked the version numbers):
PHP Fatal error: Uncaught exception 'PDOException' with message
'SQLSTATE[IMSSP]: This extension requires the Microsoft SQL Server
2012 Native Client ODBC Driver to communicate with SQL Server. Access
the following URL to download the Microsoft SQL Server 2012 Native
Client ODBC driver for x86:
http://go.microsoft.com/fwlink/?LinkId=163712'
On this thread (reporting exactly the same error as me) is a solution which says that you can confirm the driver is installed by looking for the items I've mentioned above in PHPINFO: Not getting connected to Sql Server 2012!
Any help would be much appreciated!
Although it is a fairly old post, I've decided that it would be better to place my answer here instead of creating an other question...
after 3 weeks of research all over the Web and testing a lot of hypothesis around php installation, php code and drivers installation, I finally found the solution to this question.
THE PROBLEM:
I have an app that is installed on WIN SERVER 2012 SP2 and running under IIS.
The development of this app is made on a WIN 7 SP1 and running under 32-bit XAMPP 3.2.2. All of these are running PHP 5.6.
Everything is working fine on the server but I keep having this message when executed locally on XAMPP:
This extension requires the Microsoft ODBC Driver 11 for SQL Server to communicate with SQL Server
Even though I've installed this driver many times (with other php drivers found here, configure my php.ini to load php_sqlsrv_56_ts.dll and php_pdo_sqlsrv_56_ts.dll), it keeps returning me the same message...
The PDO command I've used to connect to distant MSSQL Server was:
$db = new PDO("sqlsrv:server=192.168.165.XXX;Database=testDB;", "userName", "passWord");
I have tried other drivers and it worked fairly well with ODBC driver;
$db = new PDO("odbc:Driver={SQL Server};Server=192.168.165.XXX;Database=testDB;", "userName", "passWord");
but I've found that there was some limitations with the later driver that I didn't experience with sqlsrv on the PROD server so I decided to push a little bit more my research to find a way to implement sqlsrv on my local machine...
THE INVESTIGATION:
Before connecting with PHP, I've tried to create System DSN (Data Source Name), with the ODBC Source Administrator (ODBCSA) application and test connection from there before trying to connect with my application.
Something pretty strange I have discovered with Win7, is that there are two different ODBCSA applications.
The 32-bit version of the Odbcad32.exe file is located in the %systemdrive%\Windows\SysWoW64 folder.
The 64-bit version of the Odbcad32.exe file is located in the %systemdrive%\Windows\System32 folder.
The 32-bit version of the ODBC Administrator tool displays 32-bit system DSNs, 32-bit user DSNs, and 64-bit user DSNs.
The 64-bit version of the ODBC Administrator tool displays 64-bit system DSNs, 32-bit user DSNs, and 64-bit user DSNs
Just to make sure what ODBCA your are using, check in Task manager under odbcad32.exe, if you see *32 on its right, that means its the 32-bit version.
At first, I executed the 64-bit ODBCSA, created DSN using the brand newly installed ODBC Driver 11, called ODBC_11_64 and test the connection using the ODBCSA. All worked fine. When I tested my code I received an other error message:
The specified DSN contains an architecture mismatch between the Driver and Application
Ok then, I tried to create an new DSN using the 32-bit ODBCSA. It was strange at first, when I've discovered that there was no version number aside some driver names and I received this error from the ODBCSA:
The setup routines for the ODBC Driver 11 for SQL Server could not be found. Please reinstall the driver.
and an other message:
Component not found in the registry
It was obvious that there was an installation problem and the later message point me in the right direction, the Registry...
Starting regedit as admin, I've found that all 64-bit ODBC drivers can be found here:
HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI
All 32-bit ODBC drivers can be found here:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ODBC\ODBCINST.INI
While trying to access the 64-bit key (\ODBC Driver 11 for SQL Server), I was able to display key values but when I tried to access the 32-bit key, I received this message:
Error Opening Key, ODBC Driver 11 for SQL Server Driver cannot be opened.
An error is preventing this key from being opened.
Details: Access is denied.
THE SOLUTION:
By right clicking on the 32-bit faulty key I was able to access permission interface. I was then able to add my username (I could also add a group) and granted full Control on the registry key.
I then came back to creating an new DSN using the 32-bit ODBCSA and ODBC Driver 11 for SQL Server, tested the connection with SUCCESS! :-)
I when back to my application and found that I was able to access the distant MSSQL SERVER using sqlsrv, on my local machine.
All along it was the driver installation package that was faulty! I should had install permissions to SYSTEM, users and administrators to the key has it did with the 64-bit registry key for this driver.
It was a pretty long story but I thought it was worth it, since a lot of persons tried to solve this complex problem, going in many different directions without success. Its also my contribution to all of you, who failed to find the solution but helped me in my investigation ;-)
i have fond some config in php.ini but was noted;
;extension=odbc
;extension=pdo_mysql
;extension=pdo_oci
;extension=pdo_odbc
remove “；” before, restart service, and it is worked!
In the end I solved this by installing the "Microsoft® SQL Server® 2012 SP1 Command Line Utilities" from here (SqlCmdLnUtils.msi):
http://www.microsoft.com/en-in/download/details.aspx?id=35580
No idea why this worked but there it is.
Im trying to run a shell with cakephp but I'm not able to do it due to a SQL connection error, I'm always getting this
Warning:mssql_connect(): Unable to connect to server: XXXXX I'm sure the config for the data source is correct as I'm able to connect using the website side of the app.
Have anyone stumble with something like this?
BTW the webserver and the mssql server are not the same, they are on different hosts.
Environment Info ( I agree is a mess... ):
Web server
Windows server 2003 R2
PHP-5.2.4
IBM http server 6.1
Cakephp 1.2
DB Server
Windows server 2003 R2
Microsoft SQL server 2005
I have isolated the problem and found is not cakephp related, I created a script with just this line of code
mssql_connect('XXXX', 'YYYY', 'ZZZZ', true);
Giving me the same error. This should be something different between CLI and how php is run from the HTTP server.
Thank you!
Make sure you specify the port to connect to (usually 1433). If that still doesn't work its possible you need to play with named pipes settings. More information can be found in the comments on the PHP site: http://ca3.php.net/function.mssql-connect
I would also suggest you look into using the Microsoft SQL Serv drivers for PHP, they are much better maintained than the mssql ones. http://www.microsoft.com/download/en/details.aspx?id=20098 Here is an article explaining the differences: http://blogs.msdn.com/b/brian_swan/archive/2010/03/08/mssql-vs-sqlsrv-what-s-the-difference-part-1.aspx If you do go the sqlsrv route (and I really suggest you do) here are the connection parameters: http://php.net/manual/en/function.sqlsrv-connect.php Use example 3.
Here are the steps I followed to narrow and then fix the problem:
Check which php.ini is your cli using by running the next command: php -i
Isolate the problem, I was thinking it was something with cakephp, but at the end every problem is related to a single line in php, my problem was around this line of code mssql_connect('XXXX', 'YYYY', 'ZZZZ', true);
Based on the info provided here I found out that the next dll was outdated or not compatible with Windows Server 2003, just get ntwdblib.dll ver. 2000.80.2039.0, use this exact version as others like ver.2000.80.194.0 didn't worked for me.
As #charles mentioned if you are not working already in a project already deployed use sqlsrv drivers as those are maintained currently and the mssql are basically getting deprecated.
Thanks!
