I am trying to run gearman client from php shell_exec but it always throw following error GearmanClient::do(): send_packet(GEARMAN_COULD_NOT_CONNECT) Failed to send server-options packet -> libgearman/connection.cc:485 in /var/www/html/client.php
But if i run it from terminal then it works but not from php shell_exec. Even i passed server name and port in addServer method
I am running on centos 6.2.
Client.php
$client= new GearmanClient();
$client->addServer('127.0.0.1',4730);
print $client->do("reverse","Testing");
worker.php
$worker= new GearmanWorker();
$worker->addServer("127.0.0.1",4730);
$worker->addFunction("reverse", "my_reverse_function");
function my_reverse_function($job)
{
return strrev($job->workload());
}
Make sure your gearman packages are installed. Or manually installed if needed. Sometimes upgrading your system may cause your packages to be lost.
Second check your or launch it in debug mode as stated here http://gearman.org/getting-started/
gearmand -vvv
and then launch it run in the background
gearmand -d
I read on other questions treated to this matter that changes from
$woker->addServer('127.0.0.1',4730);
to
$worker->addServer('127.0.0.1:4730');
The same for $client->addServer('127.0.0.1',4730);
I have install Hadoop 1.2.1 and Hbase 0.94.8 in psudo-distributed mode in my ubuntu system running Ubuntu 12.04. Everything is working fine and all the deamons are running. In order to access hbase using php I downloaded and installed thrift 0.9.1.
$ thrift -version
Thrift version 0.9.1
But when I try to start the thrift server using the command
$ /usr/lib/hbase/hbase-0.94.8/bin/hbase thrift start
the thrift server begins to start. But at a certain point the terminal hangs. the last few lines of the terminal were

I'm using Windows 7, 64 bits, and PHP 5.3.5.
memcache is showing as this in phpinfo:
Active persistent connections: 0
Version: 2.2.5
Revision: $Revision: 1.114 $
And I'm also getting a connection error Notice: Memcache::get() [memcache.get]: Server localhost (tcp 11211) failed
This is what I did:
1) I installed and ran the 64 bit memcached service: http://s3.amazonaws.com/downloads.northscale.com/memcached-win64-1.4.4-14.zip.
2) I copied php_memcache.dll (https://thinkam.googlecode.com/files/php_memcache-cvs-20090703-5.3-VC6-x86.zip) into php/ext.
3) I added extension = php_memcache.dll in php.ini.
4) I restarted XAMPP.
What could I be missing?
* Update *
Memcache seems to be listening now on port 11211, but now from my application I get the following error:
Notice: Memcache::get() [memcache.get]: Server 127.0.0.1 (tcp 11211)
failed with: A connection attempt failed because the connected party
did not properly respond after a period of time, or established
connection failed because connected host has failed to respond.
(10060)
You must run memcached server in Windows Control Panel->Administration->Services.
Run path/memcache.exe -d start and make sure memcache is started
As #Gigala say in comments you can get another php_memchace.dll for different php versions from here http://windows.php.net/downloads/pecl/releases/memcache/3.0.8
Download the extension for your php version following this example:
php_memcache-3.0.8-5.3-nts-vc9-x86.zip as "5.3" must be your php version
This works for me
I am trying to connect to Oracle 11gR2 Xe on Ubuntu 13 server from another computer in the network, via PHP.
I am using installs and examples followed from oci_connect like here:
<?php
query_cities();
function query_cities() {
if {
$c = oci_connect("hr", "hr", "localhost:1521/XE");
;
} else {
echo "No connection"; }
?>
or another example like:
$c = oci_connect("hr", "hr", "192.168.1.33:1521/XE");
I have already enabled the remote connection in DB via SqlPlus
SQL> EXEC DBMS_XDB.SETLISTENERLOCALACCESS(FALSE);
and i have unlocked the user HR
SQL> ALTER USER hr ACCOUNT UNLOCK;
but I can only find some connection via IPv6 on the network from SQL Developer, like netstat:
tcp6 0 0 192.168.1.33:1521 192.168.1.2:57563 ESTABLISHED 14843/oracleXE
tcp6 0 0 192.168.1.33:1521 192.168.1.2:59314 ESTABLISHED 15665/oracleXE
not from my browser and they are not on tcp IPv4. The browser window remain white .. no reaction, unresponsive and no error message.
Should this be due to the TNSLR IP is active only on IPv6 or non of the oci_connect formulas are good enough or I am missing some other else?
I would appreciate any help on this issues
Alright, on the basis of received advice to seek the error in logs, I've found the message "*There is something wrong with your system - please check that ORACLE_HOME and LD_LIBRARY_PATH are set and point to the right directories*" and I decided to go through the sophisticated process of installing the Oracle InstantClient and reinstall OCI8 package, after the model from st-curriculum.oracle - with very small modifications, as follows:
Oracle 11g R2 XE database and Apache2 / PHP server have been apriori installed on Ubuntu 13.10 server and system prepared (with prereqiuzite, swap file, kernel parameters, memory leak error recover, libraries and chkconfig emulator), as described in many posts.
I stopped apache2 server
service apache2 stop
and started DRCP connection pooling as in st-curriculum.oracle.com
I created a user named PHPHOL (and alternate install Oracle's sample HR schema, if not already done at oracle install)
Next I downloaded the Basic and the SDK Instant Client packages from OTN: oracle.com/technetwork/database/features/instant-client/index-100365.html and unzipped the packages in $ORACLE_HOME, (/u01/app/oracle/product/11.2.0/xe)
Then I downloaded the OCI8 packeage from pecl.php.net/package/oci8 and installed in /opt/oci8 as instantclient
phpise
./configure --with-oci8=instantclient,/u01/app/oracle/product/11.2.0/xe/instantclient_11_2
make / make install
I set the oracle environment path as in oracle technote
export ORACLE_HOME=/u01/app/oracle/product/11.2.0/xe
LD_LIBRARY_PATH=/u01/app/oracle/product/11.2.0/xe/instantclient_11_2
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH=/opt/oci8/modules
nano /etc/ld.so.conf.d/oracle.conf
and insert: /u01/app/oracle/product/11.2.0/xe/instantclient_11_2
nano /etc/ld.so.conf.d/oci8.conf
and insert: /opt/oci8/modules
nano /etc/ld.so.conf.d/shared.conf
and insert the installed shared extensions location: /usr/lib/php5/20121212
ldconfig
Next I edited the configuration file php.ini to add: extension=oci8.so, set the date.timezone directive and added also the OCI8 1.4 extension class: oci8.connection_class = MYPHPAPP (for the st-curriculum.oracle.com examples, see link above)
I made the link: $ORACLE_HOME/instantclient_11_2/libclntsh.so.11.1. to points to $ORACLE_HOME/instantclient_11_2/libclntsh.so
Restart Oracle database and Apache services on Ubuntu 13.10 server
/etc/init.d/oracle-xe force-reload
service apache2 start
I verified in phpinfo() the oci8 was enabled, and I made the connect.php file like:
$conn = oci_connect("hr", "hr", "localhost/xe");
or like the one from st-curriculum.oracle.com example.
From another computer on the same network I connected through a browser to oracle database on Ubuntu server and I've got
Connected to Oracle!
I hope this help
I am having serious problem connecting to external ORA DB 11g from local Zend server CE.
OCI8 is enabled and running version 1.4.6 (due to phpinfo()).
I have tried many connection options (listed below) with the same error returned:
oci_connect(): ORA-28547: connection to server failed, probable Oracle Net admin error
After googling for whole day I am only able to say that this error means that PHP was able to comunicate with the server but was unable to connect to a concrete service/database and that the error shouldn't come from PHP itself...
I have set environment variable TNS_ADMIN to c:\oracle_instantclient_11_2 where the file tnsnames.ora is located containing this connection description:
MYDB =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = X.X.X.X)(PORT = 1521))
)
(CONNECT_DATA = (SID = MYDB)(SERVER = DEDICATED))
)
Using this description like
(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=X.X.X.X)(PORT=1521)))(CONNECT_DATA=(SID=MYDB)(SERVER=DEDICATED)))
I am able to connect to the server and the service/database with sqlplus console, so the connection is very right. I am also using the very same HOST, PORT and SID to connect to the server with Sqldeveloper tool. The problem is when connecting to the server within a PHP...
What have I tried so far:
oci_connect("user", "password", "X.X.X.X:1521", "AL32UTF8", 0);
oci_connect("user", "password", "MYDB", "AL32UTF8", 0);
oci_connect("user", "password", "(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=X.X.X.X)(PORT=1521)))(CONNECT_DATA=(SID=MYDB)(SERVER=DEDICATED)))", "AL32UTF8", 0);
All of these oci_connect calls above return the same error mentioned.
I had also tried the ezconnect way for 11g as stated here - [//]host_name[:port][/service_name][:server_type][/instance_name]:
oci_connect("user", "password", "X.X.X.X:1521/MYDB", "AL32UTF8", 0);
but the problem is I do not know the service name, only the service ID (SID), thus the error returned is this:
oci_connect(): ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
that says there is no service running with the service name provided (or that the ORA listener does not know of such service).

Maybe the problem is that there is unknown version of Oracle instant client though it's path is set within both the TNS_ADMIN and PATH environment variables...
My question is: does anybody know of what have I done wrong? Am I missing something? I have googled for a whole day yesterday so probably (with 99% chance) any google links You would like to provide me with I have already seen and tried...
Though this question could be considered as an exact duplicate of this one - it has not been yet answered and I guess nobody will return back to that old question even if I post a comment I am having the connection problems too. Also keep in mind that in that similar question a different error is returned and asked about.
Due to several misconfigurations and 3 days lost while looking for a solution I moved to develop on Linux server and all of the problems are gone.
What I have found:
both php_oci8.dll and php_oci8_11g.dll are depending on the Oracle Instant Client libraries
these libraries does not contain oci_ functions (like oci_connect), only ociX functions (like ociLogon) which is strange...
though I am pretty sure I have downloaded Oracle Instant Client Basic and all of the extensions, I was not able to connect to another Oracle server due to unknown charset and the error was saying I am using only Lite instant client...
I tried both 64bit and 32bit instant client version at no avail
my Apache is 64bit, windows is 64bit, PHP is 32bit, remote Oracle server is 64bit, remote Linux server is 64bit...
tried many environment settings (ORA_HOME, TNS_ADMIN, adjusted PATH to look to instant client installation) at no avail
tried uninstalling local Oracle XE server due to possible environment settings interference at no avail
almost lost my head - at no avail...
So finaly on Linux server I have no problems connecting to remote Oracle server. Somewhere (while surfing over thousands of PHP-Oracle related pages) I have found an information that "one shouldn't develop PHP application connecting to Oracle server under windows" and should stick to UNIX system instead...
So anybody experiencing similar or same problems - be so kind and do not waste Your time, install a VirtualBox, run Linux on it and move forward!
to connect php to Oracle 11g version 11.2 you need to do following;
Step-1:
login to you db with sys as sysdba and execute following scripts.
**
execute dbms_connection_pool.start_pool();
execute dbms_connection_pool.restore_defaults();
**
Step-2:
in you PHP script
**
$conn = oci_connect("username", "password", "//hostname/servicename");
if (!$conn) {
$m = oci_error();
echo $m['message'], "\n";
exit;
}
else {
print "Connected to Oracle!";
}
// Close the Oracle connection
oci_close($conn);
**
Note: i). Make sure PHP_OCI8 and PHP_OCI8_11g exertions are enabled
ii). Oracle 11 is case sensitive.

I have had the same issue and tried to connect from my local machine to a remote server.
after 2 weeks of tring I finally got it to work.
the solution is very simple but not documented in the PHP documentation
so let us take the sample PHP provided:
$conn = oci_connect('hr', 'welcome', 'localhost/XE');
what they did not mention is that it points to the default port on the server.
if yours is set up to a different one you need to specify that.
see the new example below:
$conn = oci_connect('hr', 'welcome', 'localhost:1234/XE');
try that with your specified port.
Hope this helps
Just adding my two cents, as I Banged my head against the wall with this one... If all else fails, try this, Once you have downloaded the instant client, http://www.oracle.com/technetwork/topics/winsoft-085727.html, copy it's extracted contents to the apache/bin folder. It'll likely ask you to over-write the oci.dll. Do so, then restart apache/php. With luck this will fix the problem...
Good luck.
My solution on fedora 17:
1. yum install httpd httpd-devel.
2. yum install php php-mysql php-pear php-devel
3. Install oracle instantclient:
rpm -Uvh oracle-instantclient11.2-basic-11.2.0.3.0-1.x86_64.rpm
rpm -Uvh oracle-instantclient11.2-devel-11.2.0.3.0-1.x86_64.rpm
4. pecl install oci8
This gives:
**

Please provide the path to the ORACLE_HOME directory.
Use 'instantclient,/path/to/instant/client/lib' if you're compiling

**
Just press enter.
5. Enable the OCI8 extension by creating a file, oci8.ini for example, with the following line at /etc/php.d/:
extension=oci8.so
6. service httpd restart
For the record (PHP 8.0.12), you can also try:
In the Apache bin folder, copy inside the next files
📁 apache24
....📁 bin
....... 📃oraociei12.dll
....... 📃oci.dll
....... 📃oraons.dll
You can find those files in the Instant client folder and in the bin folder.
Then restart Apache and that is.
The instant client, apache version and PHP version must be or 32bits or 64bits.
You can also try to connect using ez-connection (if you want to avoid using the tnsnames).
