Oracle Database 10.2.0.1 + Apache 2.0.59 + PHP 5.2.0
Hi all.
Where can i find the changePerm.sh script for Oracle Database 10.2.0.1?
I get the error:
Warning: ocilogon() [function.ocilogon]: OCIEnvNlsCreate() failed. There is something wrong with your system - please check that ORACLE_HOME is set and points to the right directory in /usr/local/apache/htdocs/oci8test.php on line 3
Help me, please!
Giovanni D'Ascola
in Apache dir write short file: something.php
<? phpinfo() ?>
and access it via browser to see if there is oci defined.
BTW. when you start apache you should se oracle (oci) variables to get access :-)

Can you help me?Marcello, i've already read that documentation:
"[...] Note: If you are using Oracle 10.2 but not the Express Edition, you must give the "nobody" user access to the Oracle directory. With Oracle 10.2.0.2 there is a script $ORACLE_HOME/install/changePerm.sh to do this."
With Oracle 10.2.0.2... but with 10.2.0.1?
I made "nobody" user member of the "oinstall" group (bad idea, i know), but still it doesn't works... -
Problem connecting oracle database to jsp pages using Apache Tomcat server 8.0
Well...I tried too many things..googled so many times..but still could not find solution to my problem.
I use windows 8 Enterprise Edition(if this has to do something with the problem)
Oracle 11.2.0
Apache Tomcat server 8.0
JDK 1.7
My oracle is installed in the D: drive and tomcat in c:. i copied the ojdbc6.jar file from oracle to lib directory of tomcat server.
Then i set CLASSPATH in environment variables as "C:\Program Files\Apache Software Foundation\Tomcat 8.0\lib\ojdbc6.jar" in system variables
My path variable is set as "C:\Program Files\Java\jdk1.7.0_02\bin".
My program is as follows in notepad:
<%@ page import="java.sql.*" %>
<html>
<body>
<%
Connection conn;
Statement st;
ResultSet rs;
try{
new oracle.jdbc.driver.OracleDriver();
String dbURL="jdbc:odbc:oracle:thin:@localhost:1521:XE";
String userId="system";
String pwd="moon";
conn=DriverManager.getConnection(dbURL,userId,pwd);
st=conn.createStatement();
rs= st.executeQuery("SELECT * FROM login");
while(rs.next())
System.out.println(rs.getString(1)+""+rs.getString(2));
catch(Exception e){}

I get too many errors then

>> ODBC Driver Manager ... Data source name not found
That appears to be ODBC drivers looking for a DSN (Data Set Name). If it wants a DSN, the DSN has to be specified in the code, and the DSN has to be configured in the windows host ODBC applet. So that is at least two squirrels to get in the right tree before moving forward. A ...host:...[port:]SID|service name are some of the bits needed in a jdbc connect string, and that is in no way related to DSNs. A Whole Different Animal. If it wants a DSN that might be what needs to go in the URL bit.
And ODBC setups can be confusing, especially if an x64 OS is in the mix- if that is the case there are two different ODBC configuration applets, one for x64 the other for x86, and if one gets as far as talking to an actual database it might toss an architecture error. Only way to fix that "problem" is *delete* the ODBC DSN and then run the correct (maybe the x86) ODBC config utility, and set up the DSN. Again. -

and i call from my servlet like before ...
InitialContext initCtx = new InitialContext ();
DataSource ds = (DataSource)initCtx.lookup ("java:comp/env/jdbc/pmodDb");

the datasource would return null in other word i cannot find the database
however if i tried to establish connection directly,
String u1 = "pmod_owner";
String p1 ="pmod_owner";
String path = "jdbc:oracle:thin:@192.9.200.2:1521:PMOD";
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
conn = DriverManager.getConnection( path, u1, p1 );
i can talk with the database....
so if anyone out there can help me to point me where did i go wrong?
fyi: i have put a lib which contains oracle jdbc driver called classes12.zip in my c:\tomcat\common\lib\
thank you -
Security vulnerabilities in apache that comes with oracle database.
Hi,
We are having a QA database in Oracle enterprise version 9.2.0.4 on OS : OSF1.
Recently our security team ran a test and found that the apache1.3 that comes as component of Oracle database is prone to security vulnerabilities. Also they suggested to remove the apache or upgrade to latest as remedy.
When contacted to Oracle support, Oracle team replied apache upgrade should not be done instead latest apache seprately can be installed as reverse proxy. But when asked for steps/document there is no reply. Anyone faced this problem can provide any help/suggestion in this regard.
I am attaching some of the threads identified by our Security Team for reference.

Issues/Problems between Apex 3.2.0.00.27 and Oracle Database 9.2.0.1
I don't know what problem is.
I was planning to install Oracle Application Express into my server.
So, i made a fresh database installation with Oracle Database Enterprise Edition 9i release 2 (9.2.0.1) and setting up Oracle Application Express 3.2.0.00.27 to use it with it.
The installation was succesful.
But I am having problems to create workspaces using the Admin option: Manage Worspaces --> Create Worspace.
After open these option, the page ask me to enter Workspace Name and Workspace Description.Then appears the page where I need to enter re-use existing schema, schema name, schema password and space quota. When I press the next button, the CPU increase to 100% use and the server, even when it does not freeze, stays in the last page and not move to the next want for a long long time.... more thant 3 hours.
I read at the apache logs and didn't find something to show me the possible causes of these behaiviour.
Apache logs
access_log.txt -------> "POST /pls/apex/wwv_flow.accept HTTP/1.1" 302 163
ssl_engine_log -------> Failed to release global mutex lock

[error] mod_plsql: /pls/apex/wwv_flow.accept ORA-3113
ORA-3113: end-of-file on communication channel
I am really confuse because I thougth that Oracle application Express is certified with Oracle Database EE 9.2.0.1
My server spec are:
Windows XP with SP2
500Mb Ram Memory
7.2 Gb Free Disk Space
Please any idea about which can be the possible problem/solution for that.
Best Regards

PanamaWell I think it is kind of wasted of time to try to figure it out which caould be the possible cause, once you told me that Apex works with 9.2.0.3 or higher and has an issues with earlier versions.
I already download the last release for 10g, so I hope it solve the problem and let me install and setup properly oracle application server.
I know it is kind of hard work to do to install 10g rel 2 but, well, is the only solution, it seems.
thanks for everything.

Try either "select swa.* from sw_assets swa" or "select all from sw_assets swa", that should get around the problem.
Also (just being thorough) make sure that you specifically created your statement as being updatable (stmt = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE) ).
I would not normally expect a NullPointerException when encountering this "feature", but then I don't often use the ODBC bridge.
Good luck! I hope this helps. -
How to insert a image file into oracle database
hi all
can anyone guide me how to insert a image file into oracle database now
i have created table using
create table imagestore(image blob);
but when inserting i totally lost don't know what to do how to write query to insert image fileHi I don't have time to explain really, I did have to do this a while ago though so I will post a code snippet. This is using the commons file upload framework.
Firstly you need a multi part form data (if you are using a web page). If you are not using a web page ignore this bit.
out.println("<form name=\"imgFrm\" method=\"post\" enctype=\"multipart/form-data\" action=\"FileUploadServlet?thisPageAction=reloaded\" onSubmit=\"return submitForm();\"><input type=\"FILE\" name=\"imgSource\" size='60' class='smalltext' onKeyPress='return stopUserInput();' onKeyUp='stopUserInput();' onKeyDown='stopUserInput();' onMouseDown='noMouseDown(event);'>");
out.println(" <input type='submit' name='submit' value='Submit' class='smalltext'>");
out.println("</form>"); Import this once you have the jar file:
import org.apache.commons.fileupload.*;Now a method I wrote to upload the file. I am not saying that this is correct, or its the best way to do this. I am just saying it works for me.
private boolean uploadFile(HttpServletRequest request, HttpSession session) throws Exception {
boolean result = true;
String fileName = null;
byte fileData[] = null;
String fileUploadError = null;
String imageType = "";
String error = "";
DiskFileUpload fb = new DiskFileUpload();
List fileItems = fb.parseRequest(request);
Iterator it = fileItems.iterator();
while(it.hasNext()){
FileItem fileItem = (FileItem)it.next();
if (!fileItem.isFormField()) {
fileName = fileItem.getName();
fileData = fileItem.get();
// Get the imageType from the filename extension
if (fileName != null) {
int dotPos = fileName.indexOf('.');
if (dotPos >= 0 && dotPos != fileName.length()-1) {
imageType = fileName.substring(dotPos+1).toLowerCase();
if (imageType.equals("jpg")) {
imageType = "jpeg";
String filePath = request.getParameter("FILE_PATH");
session.setAttribute("filePath", filePath);
session.setAttribute("fileData", fileData);
session.setAttribute("fileName", fileName);
session.setAttribute("imageType", imageType);
return result;
} And now finally the method to actually write the file to the database:
private int writeImageFile(byte[] fileData, String fileName, String imageType, String mode, Integer signatureIDIn, HttpServletRequest request) throws Exception {
//If the previous code found a file that can be uploaded then
//save it into the database via a pstmt
String sql = "";
UtilDBquery udbq = getUser(request).connectToDatabase();
Connection con = null;
int signatureID = 0;
PreparedStatement pstmt = null;
try {
udbq.setUsePreparedStatements(true);
con = udbq.getPooledConnection();
con.setAutoCommit(false);
if((!mode.equals("U")) || (mode.equals("U") && signatureIDIn == 0)) {
sql = "SELECT SEQ_SIGNATURE_ID.nextval FROM DUAL";
pstmt = con.prepareStatement(sql);
ResultSet rs = pstmt.executeQuery();
while(rs.next()) {
signatureID = rs.getInt(1);
if (fileName != null && imageType != null) {
sql = "INSERT INTO T_SIGNATURE (SIGNATURE_ID, SIGNATURE) values (?,?)";
InputStream is2 = new ByteArrayInputStream(fileData);
pstmt = con.prepareStatement(sql);
pstmt.setInt(1, signatureID);
pstmt.setBinaryStream(2, is2, (int)(fileData.length));
pstmt.executeUpdate();
pstmt.close();
con.commit();
con = null;
if(mode.equals("U") && signatureIDIn != 0) {
signatureID = signatureIDIn.intValue();
if (fileName != null && imageType != null) {
sql = "UPDATE T_SIGNATURE SET SIGNATURE = ? WHERE SIGNATURE_ID = ?";
InputStream is2 = new ByteArrayInputStream(fileData);
pstmt = con.prepareStatement(sql);
pstmt.setBinaryStream(1, is2, (int)(fileData.length));
pstmt.setInt(2, signatureID);
pstmt.executeUpdate();
pstmt.close();
con.commit();
con = null;
} catch (Exception e) {
con = null;
throw new Exception(e.toString());
return signatureID;
} -
Oracle database (10.2.0.4) and HTTP server / HTML DB conflict
Hi there,
I installed a fresh 10.2.0.1 (patched with 10.2.0.4) oracle database on Oracle Entreprise linux 5.7, and HTTP server + HTML DB products from the companion CD. Both are located in different home directory:
ODB: $ORACLE_BASE/product/10.2.0/db_1
APEX: $ORACLE_BASE/product/10.2.0/apex
I just discovered that logs files ($APEX/opmn/logs/) have filled up my entire disk this week end. After some googling / digging, I've read that there is a conflict between the ONS services that run for both products on the same port. Opening the configuration files of both products:
+$ODB/opnm/conf/ons.config+
+$APEX/opnm/conf/opnm.xml+ (btw, ons.conf is empty)
I indeed saw that they both use port 6113 as local port and 6200 as remote port. The workaround I've found in variuos places is to either change the port number, or unsuscribe ONS for the database listener (and sometimes both).
Question 1: what is the best solution ? what are the consequences for the database listener in case of unsuscribtion ?
I also saw that opnm.xml in APEX configuration file is making use of the $ORACLE_HOME environment variable, which I define in my /etc/profile as $ORACLE_BASE/product/10.2.0/db_1. So I guess the opnm of APEX is looking at the wrong place... Yet if I change ORACLE_HOME in my /etc/profile, I won't be able to run dbstart upon stgartup, as it is run using ORACLE_HOME in a init.d script...
Question 2: Can someone clarify things up about the exact relationship between oracle database and HTTP server ? How should I deal with ORACLE_HOME environment variable, which one use it and when... ?
Note that I'm completely new to Oracle (and hence APEX).
Thanks in advance!Billy Verreynne wrote:
There should be no conflicts - except for configuration ones.
Oracle is multi home capable. Thus multiple Oracle s/w products installed into different homes and these products running side by side.
The conflict is system resources - like a TCP port. That port cannot be shared by multiple processes. So you need to make sure that each s/w component that needs a TCP listener end-point, has a unique port number allocated for it to use.
As mentioned, the Oracle Apache server is an Oracle client with respect to Oracle client-server architecture. It simply needs a client OCI driver to connect to the Oracle database instance. So whether you run Oracle Apache on the same server as the database instance, or on another server all together - this makes no difference. The Oracle Apache s/w will be using its home for running. It has no need for anything from the database instance's home directory. Thus there are no conflicts - as long as you correctly keep them separated and not set the wrong home for the wrong component or include the wrong path (to another home's executables).
OK, so to summarize a bit:
- I should just be carefull when running startup script which will launch all services upon startup, i.e. changing the value of ORACLE_HOME before running each product startup script (dbstart => ORACLE_HOME = (..)/10.2.0/db_1, opmnctl => ORACLE_HOME = (..)/apex). I'm still quite worried because ORACLE_HOME is heavily used in opmn.xml but anyways.
- That's basically it: when each product's services are running, they do not use ORACLE_HOME (and such) anymore, hence no conflict from this point of view.
Also do not attempt to use IPC connectivity between the mod_plsql Apache module and the database instance. Does not make sense ito performance. Shared server should be considered and localhost TCP connectivity can be used.Well as I don't really know IPC yet, so hopefully I won't get into troubles. Just to be clear about that, i've this in my listener.ora:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /opt/oracle/app/oracle/product/10.2.0/db_1)
(PROGRAM = extproc)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = apex.nwk)(PORT = 1521))
Does that mean that ICP will be used somehow ?
Thanks again from your help.

Perhaps you got the wrong db name? Or schema name?
Everything looks good so most probably there simply is some little typo somewhere.
Hope this helps

Hyperlink target connects from Outlook e-mail to file in Oracle database
Greetings.
Due to lack of permissions, I cannot create text file on the UNIX server.
This will not be changed.
I have stored the file in the Oracle 11g database.
I want to send e-mail from PL/SQL with attached file.
No UNIX scripts at all.
It is a big file.
Thought crossed my mind.
Can I send e-mail from PL/SQL containing a hyperlink which connects to the file stored in the Oracle database ?
The link target is a file stored in the Oracle database.
Has anyone done this before?
Let me know your ideas.
Thank you.Oracle Freq wrote:

No UNIX scripts at all.Can be done using UTL_SMTP or the newer UTL_MAIL.
Attachments to e-mails are just that - the contents of the file is attached to the body of the mail. The mail arrives at its destination, the mail reader recognises the attachment and enables it to be saved to disk (or opened/viewed).
This is standard stuff.. see MIME for details on how to construct a message body that includes attachments.
Can I send e-mail from PL/SQL containing a hyperlink which connects to the file stored in the Oracle database ?
The link target is a file stored in the Oracle database.Yes. You need a web server that has been configured with Oracle "+access+" - the default is using Oracle's Apache server that includes a module called mod_plsql. This module enables the web browser to use a URL that refers to a web enabled PL/SQL procedure in a specific database schema - and pass parameters (as part of the URL's query string) to the procedure.
You can also use Oracle EPG (Extended Procedural Gateway I think is what the acronym means). This provides a web server directly inside the Oracle instance via the XDB (integrated XML database) option in Oracle. It too has a mod_plsql type module that provides an interface (via http) to web enabled PL/SQL procedures.
This procedure can be a "+document download+" procedure. Oracle provides a system procedure called WPG_DOCLOAD.download_file()+ that you can use inside that web enabled PL/SQL procedure. This will return the contents of blob/clob as a "file" to the web browser.
For example, a download web-enabled procedure will simplistically look something as follows:
create or replace procedure downloadFile( fileName varchar2 ) is
b blob;
mimeType varchar2(50);
begin
select
file_content, mime_type into b, mimeType
from my_documents where file_name = fileName;
OWA_UTIL.mime_header( mimeType, false );
HTP.p('Content-Length: ' || DBMS_LOB.getlength(b));
OWA_UTIL.http_header_close;
WPG_DOCLOAD.download_file( b );
end;The URL will look something like:
http://my-webserver.my-domain.com:7777/pls/ora/scott.downloadfile?filename=somefile.docwhere:
scott.downloadfile = name of PL/SQL procedure
filename=somefile.doc = parameter name values to pass to procedure -

Please help, urgent! How to hold the connection to oracle database
I used java to connect Oracle database using thin driver. But I found out the connection will be closed very soon if I did not make any request of query. I query the database like after 1 mins without doing anything, my application will dead for about 2 mins, then everything become normal again.
How can I hold the connection or is there any other solution? thank you!Duffy is, as usual, correct. If you have a single-user environment, then holding onto a connection is probably okay (not desirable but also not pernicious). However, once you have more than one user, you will want to use a connection pool. Jakarta Commons (jakarta.apache.org) has an open source pool that is reliable.
But the fact that you are having additional problems makes me believe you are missing a few fundamental concepts, such as transactions. Even if the connection dropped, you should be able to reconnect without issue (granted, with some additional latency). The only time it would pose an issue (above and beyond the ones mentioned above and in previous replies) is if you are not managing your transactions properly.
In short, take some tutorials on JDBC, DataSource, connection pools and transaction management.

Urgent : store and retrieve image to oracle database thru applet
hi all
i want the code sample for storing the image to oracle database
development enviornment:
server : oracle 9i , apache web server
client : ie6 browser
i am connecting to oracle database thru applet using oracle jdbc thin driver
can anyone give me details about storing image to db
1) what datatype should be used in table for image?
2) my image files are on client machine... can i directly read those files from browser or first i have to copy those files to server?
3) .gif files will do or what should be the fileformat?
4) java code to store it to database (i am using jdk1.3)
5) how to retrieve it back from database and display it in awt panel ?
its very urgent ...
i am doing some r&d and trying to do using blob....
but it will take some time ...
i will really be thankful if someone sends detail code....
thankx in advance ....Hi,
The code below might answer few of your questions.
There is a restrcition on size of image, it must be less than 4KB.
//Code to insert image in database
//mytable is the table name that contains two fields in databse:name,image of type varchar and blob
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection con =null ;
Statement stmt =null ;
con =DriverManager.getConnection ("jdbc:oracle:thin:@<hostname>:1521:orclsid", "system","manager");
PreparedStatement preparedStatement = con.prepareStatement("insert into mytable (name,image) values (?,?)");
preparedStatement.setString(1,"Amol");
InputStream inputStream = new BufferedInputStream(new FileInputStream("C:\\WINNT\\Temp\\netscape\\images\\menubg.jpg"));
preparedStatement.setBinaryStream(2, inputStream, inputStream.available());
preparedStatement.executeUpdate();
preparedStatement.close();
inputStream.close(); To retrieve image,here is the snippet
ResultSet resultSet = stmt.executeQuery("select image from mytable'");
if (resultSet.next())
byte[] image1 = resultSet.getBytes("image");
FileOutputStream fos=new FileOutputStream("c://splash11.jpg"); //will retrieve bytes and create a file
//by the name specified
fos.write(image1);
