Php, oracle connectivity.

Hello All,
I have a webserver that has php4,apache1.3 and oci8 instant client installed, and have a seperate oracle 10g db server, the php-oracle connectivity is fine when i run php code from db server but it gives me connectivity error when it runs from web server, error " ocifreestatement(): supplied argument is not a valid OCI8-Statement resource in /apache/htdocs/.....php on line..." while even when i made telnet to my db server 1521 port from web server it shows that listener is working, any idea ? thanks

Hello,
My developers have changed all the API´s to OCI8 and the code is able to connect with oracle 10g with php4 but, i am still getting this warning .i.e
Warning: ocifreestatement(): supplied argument is not a valid OCI8-Statement resource in /apache/htdocs/English/tender_list.php on line 340
i am unable to figure it out, every thing is working fine but still i am getting it ?
thanks

PHP Oracle connection randomly slow

Hello,
I have a very strange problem concerning the connection to a oracle database with php. Sometimes the same SQL-Statement takes a very long time to load for no obvious reason (more than 5 minutes). But if you try it later it pops up at once. During the waiting time Toad is just showing "SQL*Net message from client" for the session.
Here the code:
$db = "<connection string>";
$c = oci_connect("user", "pwd", $db);
$s = ociparse($c, "select content from database WHERE CATEGORY = '$category'");
if(ociexecute($s)) {
while (ocifetch($s))
echo ociresult($s, "CONTENT");
Maybe I should also mention that I'm using a page with frames with a navigation bar on the left which loads the code in the frame on the right with the variable $category. We are using Oracle9i Release 9.0.1 .
I would really appreciate any help.

Perceived slowness is something that is dealt with by using process called "tuning". Tuning process requires an extensive knowledge because it should go from end to end, starting with the application. There may be an issue with your application, database, operating system, middle tier or network and one has to know all of the above to be able to tune the application properly. It's always the application one tunes, because it's the application that makes the end users unhappy. In your posts, there is not enough information to even begin thinking about tuning, so I will outline the tuning process for you. One always begins the tuning process by blaming the network and by letting the network engineers use sniffer and dig out the slow component. Typical response from the network people is "network is OK but the server XXX is slow with responses
and that's what causing the timeouts"). Now you know where the problem is so you can concentrate on a single server and figure out what the problem is. Whatever the problem is, it is usually solved by improving the cache hit ratio by increasing the SGA. Network engineers are
used to that and they do not mind, but if you want to be mr. nice guy, you can go directly to your boss and ask him for more memory. That is so called modified method C, by Cary Millsap. That is why it's called "method C".

Using php to connect to Oracle Database 11g Release 2 Enterprise Edition EE

Greetings everyone!
Please i dont know how to connect to Oracle Database 11g Release 2 Enterprise Edition with php even though i connected with php successfully with Oracle Database 11g Express Edition with the php code below. can someone help please...Note im referring to oracle EE not XE.
define('ORA_CON_UN', 'hr'); // User name
define('ORA_CON_PW', 'Adlibs14$'); // Password
define('ORA_CON_DB', '//localhost/EE'); // Connection identifier
// use constants defined in anyco_cn.inc
$conn = oci_pconnect(ORA_CON_UN, ORA_CON_PW, ORA_CON_DB);
if (!$conn) {
db_error(null, __FILE__, __LINE__);
Edited by: user11273096 on Jul 15, 2011 12:03 AM

Find the hostname and service name of the database and use those values in the ORA_CON_DB constant.
Use 'lsnrctl status' on the database host to find the service name.
If you use a "tns" alias, you may need to create a tnsnames.ora file where PHP can access it.
Set the environment variable TNS_ADMIN (on Linux) to the directory containing the file.
See the section "Oracle Database Name Connection Identifiers" p 102 of the free book

PHP/Oracle/Apache on Windows mid tier

Hey,
I am trying to set up PHP to connect to my oracle instance using apache.
The PHP/Apache set up is on XP, which I also have a 9i client installed. I am trying to then connect to a database on a linux box. the 9i client works fine, SQL*Plus and everything else works great.
However, when I try to run my PHP I get the following error:
Fatal error: Call to undefined function: ocilogon() in c:\program files\apache group\apache\htdocs\pear\markondo\test.php on line 12
I have set the php.ini file to add oci extension but am not convinced that it is being pick up, hence the error !
Any help would be really appreciated,
Thanks,
Mark

Try this link:
http://www.php.net/manual/en/install.windows.php
You're right, it probably means PHP is not loading the php_*.dll extension for whatever version of Oracle you are running. The link above has some good comments by users who are struggling with you're problem.

Oracle Connection Pool failure in COM+

I am having some trouble trying to get a specific database to work with an application that makes use of a COM+ Application.

Not being an expert in Oracle, I have been able to dig up a little bit of information that might be of use ...
a) Our tnsnames.ora indicates that the connections are to be DEDICATED and running Toad bares this out -- dllhost ends up with a single connection.
b) most of the database initial set of parameters seem to be very similar. The only difference I noticed was that the archive log mode and db_cache_advice are ON for production.
c) We have little control over how the connection strings are being created internally in this COM+ application, but however they are created it works for UAT and doesn't for PROD.
d) When we go into our web application and hit a page that makes use of the COM+ component to render, it will work the first time but when I do a simple browser refresh it will usually fail on the 2nd or 3rd time. Almost like it is trying to expand the connection pool size and the oracle server is throwing up.
If I didn't mention earlier the two database instances run on different servers but the application server is exactly the same. We only change the alias we are using for the database (both are defined in tnsnames) and the password used to make its connection.
Does anyone have any clues on this one? I am really spinning my wheels trying to figure out what could cause this type of situation. Anything at all would be very helpful.

It appeared to us that the problem was with the Oracle server and that it might have been failing when we were trying to expand our application connection pool size or basically obtain more connections.
The biggest indicator of this is that we run the same application code against two different databases and one works and one does not work. Having said this, I suppose the problem could be rooted in a data error instead of an oracle server error ...
Is there a specific trace file on the oracle server that would help me point to any error that is truly an oracle server error? Sorry I am very new to Oracle.

Errors in PHP/Oracle article

Hi,
There are a few errors in the article dealing with PHP/Oracle located at http://otn.oracle.com/oramag/webcolumns/2003/techarticles/hull_php.html
In the listing for the section called "How to use a database":
- $mycursor ora_open ($conn);
should be
$mycursor = ora_open ($conn);
- echo "RESULT: ora_getcolumn ($mycursor, 0), ora_getcolumn ($mycursor, 1) <br>";
The above is not the way it works in PHP and you won't get the expected results. You can throw variables in between your double-quote delimited strings, but not function calls. You'll have to concatenate the function calls like this:
echo "RESULT: ".ora_getcolumn ($mycursor, 0).", ".ora_getcolumn ($mycursor, 1)."<br>";

Leendert:
Thanks for the comments. The first one is an obvious typo. The second
is a pretty obvious mistake which I missed while reviewing this. Although
PHP will expand variables in a string like that, it will not handle
function calls. How could it. I just tried it, and concatenation works
just as you suggest. Thanks for the corrections, and we updated the
article.

Oracle Connection Manager

Hi,
i'm having a problem configuring Oracle Connection Manager. It does start the instance of connection manager
Summary of my environment is
10g Application server and infrastructure machine OS: Windows 2003
9i Database Server: Windows 2003
Client : Java Applet
JDBC driver type : THIN
Installed: 10g Infra first and then 10g midiier(portal and wireless) in seperate oracle homes on the same machine. Eveything is up and running as i was able to login seperately in infra and midtier enterprise managers.
Final Goal : Trying to connect to an Oracle 9i database on a differnt machine than the appserver using an applet, thin drivers and Oracle Connection Manager
Problem : Connection manager instance not started however cmanADMIn service started.
CMCTL:CMAN_oracle9-app> administer cmanOracleAS
Current instance cmanOracleAS is not yet started
Connections refer to (address=(protocol=tcp)(host=10.10.1.101)(port=1610)).
The command completed successfully.

Steps done to configure Oracle Connection manager
1. Copied 4 .exe (CMADMIN, CMCTL,CMGW,CMMIGR) files to bin folder of Appserver or midtier's main ORACLE_HOME/BIN folder.
2) created a cman.ora file and copied in appservers /NETWORK/ADMIN directory
3) On cammand prompt type CMCTL...ADMINISTER cman_OracleAS where cman_OracleAS is the name of cman instance used in cman.ora file.

Forgot to mention that
cmanOracleAS.log file i.e connection manger log file is as follows.
It says does not currently know of service 'cmon' but i have the rule which
allows cmctl to conect locally with 127.0.0.1 .

Certificates in lieu of Oracle connection Manager for our Applets -- Help!!

I support an application named IDEA out of New York. The IDEA application is an INTRANET application for use within our company Firewall.
Currently, the IDEA application's front end resides on a Windows 2000 Server running IIS 5 and JRun 3.0. The back-end runs on Oracle 8.1.7 database on a UNIX Database Hosting Utility (DHU). Our applets communicate with the back-end database using Oracle Connection Manager that is installed on the Web Host.
We are trying to migrate to the DWeb environment (Linux cluster). The linux cluster is running Apache Tomcat. We have been told that installing Oracle connection manager is not a viable solution (our company does not support it). Because of this our applets cannot communicate with our database. Below is a brief description of this limitation and also the work-around.
====================================================================================================================================================
Connecting to the Database through the Applet
The most common task of an applet using the JDBC driver is to connect to and query a database. Because of applet security restrictions, unless particular steps are taken an applet can open TCP/IP sockets only to the host from which it was downloaded (this is the host on which the Web server is running). This means that without these steps, your applet can connect only to a database that is running on the same host as the Web server.
If your database and Web server are running on the same host, then there is no issue and no special steps are required. You can connect to the database as you would from an application.
As with connecting from an application, there are two ways in which you can specify the connection information to the driver. You can provide it in the form of host:port:sid or in the form of a TNS keyword-value syntax.
For example, if the database to which you want to connect resides on host prodHost, at port 1521, and SID ORCL, and you want to connect with user name scott with password tiger, then use either of the two following connect strings:
using host:port:sid syntax:
String connString="jdbc:oracle:thin:@prodHost:1521:ORCL";
conn = DriverManager.getConnection(connString, "scott", "tiger");
using TNS keyword-value syntax:
String connString = "jdbc:oracle:thin:@(description=(address_list=
(address=(protocol=tcp)(port=1521)(host=prodHost)))
(connect_data=(sid=ORCL)))";
conn = DriverManager.getConnection(connString, "scott", "tiger");
If you use the TNS keyword-value pair to specify the connection information to the JDBC Thin driver, then you must declare the protocol as TCP.
However, a Web server and an Oracle database server both require many resources; you seldom find both servers running on the same machine. Usually, your applet connects to a database on a host other than the one on which the Web server runs. There are two possible ways in which you can work around the security restriction:
You can connect to the database by using the Oracle8 Connection Manager.
or:
You can use a signed applet to connect to the database directly.
These options are discussed in the next section, "Connecting to a Database on a Different Host Than the Web Server".
Connecting to a Database on a Different Host Than the Web Server
If you are connecting to a database on a host other than the one on which the Web server is running, then you must overcome applet security restrictions. You can do this by using either the Oracle8 Connection Manager or signed applets. ====================================================================================================================================================
It was suggested that we implement signed applets (it is our only alternative at this time). This is where, hopefully, you can help me. We are unfamiliar with using certificates and signing applets. We need to obtain certificates that will allow our applets to connect to our oracle database on the DHU. What kind of certificates do we use? Are their coding examples of how to use these certificates? We have a CA within our company but they cannot tell us what kind of certificates we need. How many certificates do we need? Do we install any certificates on the backend database server? Any information would be greatly appreciated. We are basically trying to get our applet to work outside the sandbox by establishing a connection to the database server.Thanks in advance for your time.

If you want to connect to the database from the applet there is a third option.
Since this is an intranet application you have control over the desktops using this
application. In our company the jre ignores signed applets (as it should) because
it gives control to the user to run potentially harmfull applets from the Internet.
The way to dish out special privileges to applets is the policy, put a policy file on
you intranet and have the jre use it by specifying its URL in the java.security.
Here is some more info about security configuration of the jre:

We use Oracle jinitiator to run Oracle forms but I am not involved in that project
and do not know a lot about it. It does perform quite good though.

Eston,
Have you searched SUN's java Web site? Maybe this article will help:
