Oci8 and oracle thin

I am using developer 3.0 on the NT server machine, with oracle 8
First of all when i start my computer one error message raise that is "one of your service is not running please check the event log". I saw the event log that service is oraclestartorc1. who can i start this service. the other oraclelistener service is also give error message in starting.
so next thing is when i click on the connection UI to make a new connection. I click on the oracle oci8 and use localhost = 127.0.0.1 and protocol = TCP and SID = orcl then error message comes that "ocijdbc8 is not in share path" who can i remove this problem also. I also use BEQ protocol to connect but the error message is same. When i use oracle thin driver then it raise message "could not establish the connection with adapter". Who can i remove this also. when i use the jdbc-odbc bridge it success the connection in test. But it does not show in connection. Who can i get driver for oci8, oci7 or for thin. Simply i want to connect my computer local database. my oracle directory is "orant" please help me thanks..

Jawada,
Try the following:
1. Make sure your ORACLE_HOME directory is in your PATH (JDeveloper needs this so it can find the OCI driver's client-side DLL).
2. Make sure you have an alias set up for your database in your TNSNAMES.ORA file (usually located in ORACLE_HOME\network\admin). I believe previous posts to your other questions provided instructions for this.
3. Within JDeveloper, select Tools | IDE Options... from the menu. Choose the Environment Tab, and in the Oracle Home section, choose the name of your Oracle Home or choose Default Home from the Select an Oracle Home list. (this isn't really required unless you have multiple Oracle Home's installed on your machine).
4. When creating your connection within JDeveloper:
a. Choose Oracle JDBC OCI-8 from the Select a JDBC Driver list.
b. Choose Existing TNS Names from the Select a Connection Method list.
c. Choose the alias for your database from the TNS Service list (this list will not appear until you choose Existing TNS Names from the Connection Method list.

Database connection encryption and integrity with ColdFusion and Oracle thin client

As ColdFusion datasource we are using the Oracle thin client to connect with the database. So, basically we are using a JDBC URL such as jdbc:oracle:thin:@... and as Driver Class oracle.jdbc.OracleDriver. This works successfully however we would like to set encryption and integrity parameters as well. In Java this is done similarly by setting a Properties object prior to getting a connection as follows:
Properties prop = new Properties();
prop.put("oracle.net.encryption_client", "REQUIRED");
prop.put("oracle.net.encryption_types_client", "( DES40 )");
prop.put("oracle.net.crypto_checksum_client", "REQUESTED");
prop.put("oracle.net.crypto_checksum_types_client", "( MD5 )");
OracleDataSource ods = new OracleDataSource();
ods.setProperties(prop);
ods.setURL("jdbc:oracle:thin:@localhost:1521:main");
Connection conn = ods.getConnection();
Is there a way that I can pass these parameters to the ColdFusion datasource. Ideally, I would love to do this centrally in such way that a change to all the cfquery or cfstoredproc is not needed.
I also know that in application servers such as Oracle AS there is an option when creating a datasource which says "Add Properties". In there you can add such properties. So, I was thinking of maybe creating a JNDI DS in the app. server and then magically connecting to it but this may have some impacts on the app.
Besides this I was also thinking of communicating with the CF datasource through the CF admin API (cfide.adminapi.administrator) and also the option of extending the Oracle driver so that when CF connects with it these params are already set.
I would love to have your professional opinion and suggestions on this.

I believe the thin driver actually needs the IP address (not the DNS name). Also, is "java" the name of the Oracle instance to which you are trying to connect?
Try the following:String driver = "jdbc:oracle:thin";
String dbIP = "W2RZ1NXG01's IP address";
String dbPort = "1530";
String dbSid = "java";
String dbUser = "Admin";
String dbPswd = "apassword";
String cnctStr = driver + ":@" + dbIP + ":" + port + ":" + dbSid;
try
    Class.forName("oracle.jdbc.driver.OracleDriver");
    con = DriverManager.getConnection( cnctStr, dbUser, dbPswd );
    stmt = con.createStatement();
    stmt.executeUpdate(createString);
    stmt.close();
    con.close();
catch(SQLException ex)
    System.err.println( "The following SQLException occurred: " + ex );
    System.err.println( "Message: " + ex.getMessage() );

CachedRowSet problem in Weblogic 6.1 and Oracle thin driver 9.0.1

Has anyone used the CachedRowSet class successfully? (this classes are
new and from the JDBC extension pack)
I am experiencing "Not in a transaction" errors when executing
cachedrowset.populate(resultset), even though I'm inside a correct
ut.begin and ut.commit transaction.
Note I don't have these problems when I don't use the CachedRowSet
classes.
If I remove the setFetchSize(50) line, then I receive the ORA-01002:
fetch out of sequence error, which is discussed in another post on
this newsgroup.
I don't have any of these problems at all, if I use the Oracle Thin
Driver directly (i.e. not using Weblogic 6.1).
-H
Example of code:
stmt = getConnection().createStatement();
stmt.setFetchSize(50);
stmt.executeQuery("SELECT * FROM ASSET");
rs = stmt.getResultSet();
crs = new CachedRowSet();
crs.populate(rs);

Hung queries, and Oracle thin driver query timeout implementation

We are seeing occasional instances of stuck threads, where the code is in Oracle thin XA driver code waiting for a socket read for a response from the database. Usually only one thread at a time. The connection never terminates and we have to shut down WebLogic to clear it. The DBAs tell us that all connections to the 11g RAC cluster members from our hosts are idle, with no hung or long-running transactions.
This happens every few days across two WebLogic 10.3.5 clustered instances in our QA environment, usually not the same time on two servers (one had four incidents, the other had only one, in the last 15 or so days). Sometimes it has resulted in a hung server, as the driver is holding a lock that blocks other threads (today we had numerous threads block in a TX rollback).
I'm guessing our WebLogic instance somehow is not getting the connection close from the remote host. BTW, there is no firewall between us and the DB. I have not got any strong suspect for the cause (although we are running Linux on a VMWare 4.0 VM, which always worries me).
Ordinarily I'd either ask the application to set a query timeout, or set the query timeout parameter for the connection pools as a workaround (we are using a MultiDatasource), so the transaction would at least abort and the application can handle it. However, while the Oracle driver does support java.sql.Statement.setQueryTimeout(), some brief investigation on my part leads me to believe the timeout is implemented on the server side and not the client side - so that if it is indeed the case that WebLogic does not see the close on the connection, it also would never see the timeout.
Two questions:
1. Is my suspicion about server-side implementation of timeout for Oracle 11g correct?
2. If so, is there some property I can set for the driver that will implement a socket timeout? Is this "safe"?
Thanks for any help!
[ Oracle WebLogic 10.3.5, HotSpot 64 bit JVM 1.6.0_29 on RHEL 5.6 on VMWare; Oracle Thin XA driver bundled with WebLogic; Oracle RAC 11g (three-node cluster)]
Edited by: SteveElkind on Dec 3, 2012 5:25 AM

Thanks, Joe.
My investigations were heading in this direction (e.g., http://docs.oracle.com/cd/B28359_01/java.111/b31224/apxtblsh.htm#CHDBBDDA). However, for WebLogic, is it as simple as adding the following property in the Datasource Connection properties edit box in the WebLogic console?
oracle.net.READ_TIMEOUT=300000
or do I have to edit the connection URL?
I've tried this, and the Datasource restarts OK after the change, but I have no way right now to check whether it actually "works".
(we have some long-running queries; five minutes seems to be a "safe" limita for now)

Method getCustomDatum() and Oracle thin client

Hello All,
I am using WL6.1 and an Oracle thin driver. I am using the Oracle Intermedia classes

Trying to use the Oracle classes caused class cast exceptions. When using the
weblogic.jdbc.vendor.oracle.OracleResultSet, I got the error
"java.sql.SQLException: getCustomDatum is not supported by the Weblogic JDBC Driver".
I was wondering if anyone else has run into this problem? Any help would be greatly

Do you mean that I need to get to get a connection directly to thedatabase using
the Thin driver instead of getting the connection via the pool?Yes, this is the first option. Note that with using thin driver directly
you loose all advantages of using weblogic JDBC subsystem like
transactions, connection pooling and caching of prepeared statements.
I'd go with a stored procedure.

Visual Cafe and Oracle thin driver

I have created a java applet using visual cafe and oracle think

I also had this problem. Its a general security problem.
Because your trying to connect to another machine, you
must sign your applet to get full security privelages from
within your browser. The sandbox within the JVM of the browser
doesn't let you open connections to other machines.
(Although my original understanding was that if the applet
was stored locally, then you had full privelages - but it
didn't work like this for me.)
Try signing your applet.

JDK1.3 and Oracle thin drivers

I see that the latest version of the thin drivers (Oracle8i 8.1.6.0.1) are "validated" for jdk1.2.x use.
Now that jdk1.3 is out for both Solaris and Windows, can I assume that the drivers will function properly with jdk1.3? or will Oracle release new drivers for jdk1.3?

I have found that the 1.3 jdk (I am using the RC for linux) works very well with the jdbc thin driver. The performance is exceptional using the hotspot server vm.

In contrast to what many people say in this forum, it is possible to have an unsigned applet access a database. You don't even have to manipulate the client's policy-file. The requirement is that the database is located on the same machine as the applet is downloaded from.There are however other things that can break this possibility. One is the database-driver itself.
In the case of Oracle we have tried using different versions of the driver. When using version 8.1.7 or 9.0.1 things work nicely, but when switching to version 9.2 it stops working. There is a question on OTN [1]. Let's see what Oracle has to say about it.

Oci8 and oracle extensions mutually exclusive?

Does anybody know if the following extensions are mutually exclusive.
php_oci8.dll
php_oracle.dll
I can't getting both to load.
They can be uncommented in the php.ini and loaded individually but if both are used this causes a fatal error and apache fails to start and doesn't leave anything in the log file.
I am currently using php4.3.6 / NT / Apache 1.3.12 (Win32)
I am fairly new to php and don't seem to be getting anywhere fast, any help would be appreciated.
thanks

I have them both uncommented and usable. I'm using Apache 1.3.28.
Maybe your four-year old Apache version is the problem?

Thanks for the response.
I understand what you are saying...
that readers don't block writers in Oracle (the same is true in SQL Server 2000).
However, I don't see how my test case is working correctly with Oracle (the exact same code acting as I'm thinking it should with SQL Server, but I still think it is acting incorrectly with Oracle).
I have transaction A do this:
update <table> set <column2>=<value> where <column1>='1'
then I use Thread.sleep() to make that program hang around for a few minutes.
Meanwhile I sneak off and start another program which begins transaction B. I have transaction B do this:
select * from <table> where <column1>='1'
and the read works immediately (no blocking... just as you have said) however, transaction A is still sleeping, it has not called commit() or rollback() yet.
So what if transaction A were to call rollback(), the value read by transaction B would be incorrect wouldn't it ?
Both A and B use setAutoCommit(false) to start their transactions, and then call setTransactionIsolation(Connection.TRANSACTION_READ_COMMITTED).
Isn't that supposed to guarantee that a reader can only read what is committed ?
And if a row is in "flux"... in the process of having one or more values changed, then the database cannot say what the value will be ?
I can almost see what you are saying.
In letting the reader have what it wants without making it wait, I suppose it could be said that Oracle is holding true to the "only let committed data be read"
So if that's it, then what if I want the blocking ?
I want an entire row to be locked until whoever it in the middle of updating, adding, or removing it has finished.
Do you know if that can be done with Oracle ? And how ?
Thanks again for helping me.

Problem w/ 8.1.6 Thin Driver and Oracle 8.0.5

I am attempting to connect to two data hosts.
One is Oracle 8.1.6, the other is Oracle 8.0.5. The DB Admin insists the user name and passwords are the same for both.
I am using the v8.1.6 100% Java thin driver under both JDK v1.2 and v1.3. My OS is Windows2K Professional.
I can always connect to the 8.1.6 database but never to the 8.0.5 database under any circumstances. The error I receive when attempting to connect to the 8.0.5 database is:
java.sql.SQLException: Io exception: Connection refused(DESCRIPTION=(TMP=)(VSNNUM=134238208)(ERR=12505)(ERROR_STACK=(ERROR=(CODE=12505)(EMFI=4))))
Does any one have some insights here?
My test code fragment is as follows:
try{
Class.forName( "oracle.jdbc.driver.OracleDriver" ).newInstance();
String dbURL = "";
//dbURL = "jdbc:oracle:thin:@host1:1521:data_source_8_1_6";
dbURL = "jdbc:oracle:thin:@host2:1521:data_source_8_0_5";
Connection con = DriverManager.getConnection(dbURL, "test_user", "test_user");
java.sql.Statement stmt = con.createStatement();
String sq1String = "SELECT * FROM DUAL";
java.sql.ResultSet res = stmt.executeQuery(sq1String);
int rows = 0;
while(res.next()) {
rows++;
System.out.println("rows = " + rows);
catch(Exception e) {
System.out.println(e);
null

tnsping is working correctly. We can ping the host and it is listening on port 1521. Likewise, there are other applications inhouse using this datasource.
Since first posting my question, I have also tried running the test program on WinNT. Same problem arises.
Other suggestions?
