Using metalink cache of an other oracle server?

Hi,
I have two 11g RAC clusters: one can be connected to the internet, the other one not. I like to use Enterprise Manager to download and apply patches.
The cluster with internet connection can download patches and store them locally. But what about the second cluster? Can I point the second cluster to the metalink cache of the first cluster, so that I don't have to download all the patches manually?
Thanks in advance,
Frank

Sounds good. :-) Sounds like I'm looking at the problem from the wrong side: the patches are pushed to the second cluster, not pulled from the first cluster?
Can you point me to the part of the 11g documentation that describes the process? So far I could not find anything about that (besides low level information how to patch on the command line).
Thanks in advance.
Frank

Using archivelog and control file from other Oracle server

I am still bothered with my backup process.
I have 2 AIX boxes (same model, say A and B); both have BAAN 5 and Oracle 10g R2 on. Right now my colleague insists to use the export pump (cold backup) from Prod Oracle server (A) to restore the Oracle server on Box B. The Prod server has the archivelog mode turn on. But it will miss any transaction data from import pump till the crash point of Box A. So this is my confusion.
Can I pass the control files and archivelog files form Box A (prod server) to Box B and use them to restore the Box B as the latest Prod server? How?
I tried to convince them to use the RMAN backup? But not successful?
I think the best way is probably to use the Oracle Data guard. However, there is always one concern to my manager and colleague, that such process will cause the data on the restored server (failover, Box B) not recognizable by the BAAN, which define the objects (tables).
Thanks

Performing a logical backup is not useful to restore to the point of failure. The only valid and available option is a hot backup/archivelog mode. Your recovery manager backup perform a controlfile and redologfile backup, so those can be restored at the destination. You must take care of the way you perform the backup, and ensure the paths where your backup is being deposited are visible by the second node. A shared storage with same mount points is suitable in this case. A tape robot configured at both nodes is also a suitable solution.
Recovery manager perfoms a controlfile and spfile restore, too. This rman command perform the action:
SET DBID <DBID of the database,for which you want to restore the controlfile>;
RESTORE CONTROLFILE FROM <name_of_backupiece_which_contains_the_controlfile backup>';
I don't see any problem on the recovery manager side, and technically speaking, on the Oracle side it is perfectly possible to restore your database at a remote location. I don't know what happens on the BAAN side, if you are required to have it configured to be operative on the target node. You could try to clone your database at the node B, configure BAAN and prepare the proceduere in case of failure.
Configuring a dataguard is also a recomended action. So it is to think about Cold Failed Over clusters. I have recently performed a CFC configuration with BAAN. No problem it works smoothly.

Using Web Cache to Load balance Forms Server application.

Hello,
I apologize for cross posting this question in the Forms and Caching Services forum. But I thought my question will have a better chance.
I have read that it's possible to use Oracle Web Cache as a software load balancer between multiple Application Servers.
We are running Oracle9iAS R1.0.2.2.2a, with Forms/Reports6i servers on 2 Win2k boxes i.e our Forms6i application is deployed on two seperate boxes in two distinct locations. Users at each location, use their respective App Server url.
Since the application is the same i.e. Forms6i code/fmx is the same for both locations, I am looking into loadbalancing and failover capability that Web Cache might be able to provide.
I AM ONLY LOOKING AT THE LOADBALANCING & FAILOVER capabilities and NOT caching.
So basically all users from both locations will point their browser to this Web Cache and the Web Cache will direct each connection to either of the two boxes. So, if either of the boxes dies, Web Cache will divert the requests to the other box.
My concern is whether Web Cache supports this for the Forms requests that it will receive from the users. We are using Servlet Deployment of Forms, so technically, all communication is going though the HTTPD.
Has anyone done this or has any ideas as to whether it's going to work or not? Oracle's FAQ insists that Forms is not supported. But I want to make sure that even loadbalancing is not supported. And if not supported then is there any other solution.
Any comments appreciated.
Thanks,
Manish

Using Web Cache to load balance servlet-based Forms (6i and 9i) is unofficially supported. I say "unofficially" because we have actual customers doing it and getting support, but the 2 development teams (Forms and Web Cache) haven't actually done any integration testing of this sort of configuration yet. For your case, please contact your Support rep and ask what was done to use Web Cache as a load balancer for Forms6i at METRO in Germany. The Forms product managemment team is writing up a white paper to describe how to do it, but until then, you'll need to go through Support. Please contact me if you want more information.

is there an api/oci function to discover other oracle servers on a LAN? pretty much i want to provide a list of oracle servers a user can connected to.

Hey
If the Server B,C and D are no more necessary redirect this IP on the DNS level than on the oracle.

Require script or a method to Run .exe files on target computers using task scheduler or any other Windows server intigrated tool

Hi All,
We are outsourcing services to our clients. One of our clients whom we manage the whole Active directory / Exchange 2010 infrastructure have a requirement.
We would like to run a .exe file from one server to another server / servers remotely to generate a report. The challenge is that we do not have permissions on some servers to access so we cannot login manually and run the .exe file to generate that report.
(All are in the same domain restricted or non restricted)
The domain Administrator (Client) Has restricted us to login to those servers due to security reasons. And is not providing us permissions or not giving the username and password to login to those servers.
Requirement is :
To run a .exe file with some parameters in it on the restricted servers Via powershell script or task scheduler (As the task will be created by the domain admin in the server in which we have access by entering the domain account).
As we have to run this .exe file on around 60 servers (restricted) so an option should popup asking the name of the agent in which you want to RUN the .exe file or a source input via CSV will also be fine.
Can anyone tell me or can this be possible ? Is there any one who has made such a script.
Can anyone please help.

Subject: Oracle Server and UNIX Transaction Processing Monitors - 1

PURPOSE
This file contains commonly asked questions about Oracle Server and UNIX
Transaction Processing Monitors (TPMs). The topics covered in this article are
     o What is a Transaction Processing Monitor (TPM)?
     o What is the X/Open Distributed Transaction Processing Model?
     o How does the Oracle Server works with TPMs?
     o How should I position TPMs with my customer?
     o What Oracle products must a customer purchase?
     o Where can my customer purchase a TPM?
     o Availability and packaging
Explanation & Example
What is a Transaction Processing Monitor?
=========================================
Under UNIX, a Transaction Processing Monitor (TPM) is a tool that coordinates
the flow of transaction requests between front-end client processes that issue
requests and back-end servers that process them. A TPM is used as
the "glue" to coordinate transactions that require the services of several
different types of back-end processes, such as application servers and
resource managers, possibly distributed over a network.
In a typical TPM environment, front-end client processes perform screen
handling and ask for services from back-end server processes via calls to the
TPM. The TPM then routes the requests to the appropriate back-end server
process or server processes, wherever they are located on the network. Through
configuration information, the TPM knows what services are available and where
they are located. Generally, the back-end server processes are specialized so
that each one handles one type of requested service. The TPM provides
location transparency as well and can send messages through the network
utilizing lower-level transport services such as TCP/IP or OSF DCE.
The back-end servers process the requests as necessary and
return the results back to the TP monitor. The TP monitor then routes
these results back to the original front-end client process.
A TPM is instrumental in the implementation of truly distributed processing.
Front-end clients and back-end processes have no knowledge of each
other. They operate as separate entities, and it is this concept that provides
flexibility in application development. Front-end and back-end processes are
developed in the UNIX client-server style, with each side optimized for its
particular task. Server functionality can be deployed in stages, which makes
it easy to add functionality as needed later in the product cycle. It also
makes it easy to distribute both the front-end and back-end processes
throughout the network on the most appropriate hardware for the job. In
addition, multiple back-end server processes of the same type might be
activated to handle increasing numbers of users.
What is the X/Open Distributed Transaction Processing Model?
============================================================
The X/Open Transaction Processing working group has been working
for several years to establish a standard architecture to implement
distributed transaction processing on open systems. In late 1991,
X/Open published the initial Distributed Transaction Processing (DTP)
model specification and defined the first of several interfaces that
exist between the components of the model. Subsequently, other publications
and a revised model specification have been published.
An important function of the TPM in the X/Open DTP model is the
synchronization of any commits and rollbacks that are required to complete
a distributed transaction request. The Transaction Manager (TM) portion
of the TPM is the entity responsible for ordering when distributed commits
and rollbacks will take place. Thus, if a distributed application program
is written to take advantage of the TM portion of the TPM, then it,
and not the DBMS, becomes responsible for enabling the two-phase commit
process. Article 2 has more detail on this model.
How does the Oracle Server work with TPMs?
==========================================
When a TPM is used without invoking an X/Open TM component to manage the
transactions, Oracle Server needs no special functionality. The transaction
will be managed by Oracle itself. However, when the TPM X/Open TM component
is used to manage the transaction, the Oracle Server, that is the Oracle DBMS,
acts as a Resource Manager--a type of back-end process. In the case of
TPM-managed transactions, the TM needs a way to tell the RMs about the stages
of the transaction. This is done by a standard, X/Open defined interface
called XA. Article 2 of of this document gives more information about both
the X/Open model and Oracle7's use of XA.
Because the XA interface provides a standard interface between the TM and the
resource manager, it follows that the TM can communicate with any XA-compliant
resource manager (e.g., RDBMS), and, conversely, that a resource manager can
communicate with any XA-compliant TM. Thus, the Oracle Server, beginning with
Oracle7, works with any XA-compliant TM.
How should I position TPMs with my customer?
============================================
There's been a great deal of confusion about the need for TPM technology. Some
software suppliers, most notably IBM, will assert that a TPM like CICS is a
necessary requirement for high volume OLTP. Other vendors will assert that
there is seldom a need for such technology. And yet others promote TPMs as
providers of higher transaction throughput.
From Oracle's standpoint, customers might choose TPM technology under any of
the following conditions:
1. For heterogeneous database access, especially for 2PC capability
     This means that a TPM can be used to coordinate 2PC between Oracle
     DBMS and any other XA-compliant database, such as Informix. This
     does NOT provide SQL heterogeneity - SQL calls to Oracle DBMS may be
     different than SQL calls to Informix. The TPM handles the routing,
     communication, and two-phase commit portion of the transaction, but
     does not translate one type of SQL call into another.
2. For transaction monitoring and workload control
     The leading TPMs supply tools to actively manage the flow of
     transactions between clients and servers and to load balance the work
     load across all available processors on a network, not just on a
     single multi-processor system. Some TPMs also have the ability to
     dynamically bring up additional back-end services during peak work
     hours.
3. For more flexible application development and installation
     One of the key features of the DTP model is application modularity.
     Modularity, that is, the decomposition of a large program into small,
     easily defined, coded and maintained "mini-programs" makes it easy to
     add new functionality as needed. Modularity also makes it much easier
     to distribute the front-end and back-end processes and the resource
     managers across hardware throughout a network.
4. For isolating the client from details of the data model
By using the service oriented programming model, the client program
     is unaware of the data model. The service can be recoded to use a
     different one with no change to the client. To get this advantage,
     the application developer must explicitly code the server and client
     to fit the service model.
5. For connection of thousands of users
     TP Monitors, because of their three-tier architecture, can be used
     to connect users to an intermediate machine or machines, removing
     the overhead of handling terminal connections from the machine
     actually running the database. See Article 4 for more information.
There are also several cases where TPM technology is not the right answer.
These include:
1. If the customer is simply looking for a performance improvement
     The customer may have heard a theory that "higher performance
     is possible for large scale applications only if they use a
     TP monitor". First, no performance gain can be achieved for
     existing applications; in fact, they won't even run under a TP
     Monitor without recoding. Second, performance improvements have
     only been documented for large numbers of users, and "large"
     means many hundreds or thousands. Without a TP Monitor,
     Oracle Server can handle several hundred users with its normal
     two-task architecture and several times that using the Multi
     Threaded Server. For more on performance, see Article 4.
2. If the customer has made large investment in his existing Oracle
applications
     TP monitor applications must be designed from the ground up to take
     advantage of TP monitor technology. Current Oracle customers will find
     it difficult to "retrofit" a TP monitor to their existing applications.
     The Multi Threaded Server, on the other hand, allows the use of
     existing Oracle applications without change.
3. If the customer is committed to the Oracle tool set
     Currently, none of Oracle's front-end tools (Oracle Forms, etc.) is
     designed to work with TP monitors. It is possible to invoke a
     TP Monitor by using user exits. However, the fact that the TP
     Monitor model hides the data model from the client means that only
     the screen display parts of Forms can be used, not the automatic
     mapping from screen blocks to tables.
4. If the customer does not have a staff of experienced software engineers
     This is still very young technology for UNIX. There is not a lot of
knowledge in the industry on how to build TP monitor applications or
what techniques are most useful and which are not. Furthermore,
     integrating products from different vendors, even with the support
     of standard interfaces, is more complex than deploying an integrated
     all-Oracle solution. Because TP monitor technology is fairly
     complex, we recommend that you let the TP monitor supplier promote
     the virtues of their technology and differentiate themselves from
     their competitors.
What Oracle products must a customer purchase?
==============================================
If your customer is only interested in building Oracle-managed TP Monitor
transactions, the only Oracle products required are the Oracle Server
and the appropriate Oracle precompiler for whatever language the
application is being written in--most likely C or Cobol. If TPM-managed
transactions are required, the Oracle7 Server with the distributed option
is also required. SQL*Net is optional because the TPM takes care of the
network services. Article 2 describes when you would choose to have the TP
Monitor manage the transactions.
Where can my customer purchase a TPM?
=====================================
There are many vendors offering the UNIX TPM products. (Oracle does not
relicense TPMs.) Information on the most well known products is provided
below:
The following support XA:

In addition, Groupe Bull, Digital, Siemens-Nixdorf, and several other hardware
vendors are planning to redesign their proprietary TPMs to be XA-compliant and
suitable for use on UNIX systems.
Availability and Packaging
==========================
On what platforms is the XA Library available?
Oracle provides the XA interface with Oracle7 Server on all platforms that
support an XA-compliant TPM. Support for XA is included as part of the
Oracle7 Server distributed option and has no extra charge in and of itself.
Which version of XA does Oracle Server support?
Oracle7 Server supports the Common Application Environment (CAE) version of
XA, based on the specification published by X/Open in late 1991. It will
require that the TM also be at that level. This means Tuxedo /T version 4.2,
for example.
Oracle Server supports all required XA functions. There are some optional
features Oracle Server does not support, such as asynchronous operation.
None of those options affect application programming.

Oracle Server Working with UNIX TP Monitors
===========================================
Do I need XA to use Oracle Server with TPMs? If I don't use it, what are
the consequences?
There are a number of real applications running today with Oracle Server and
TPMs but not using XA. To use a TPM with Oracle without using XA, the user
would write an "application server" program which could handle one or more
"services". For example, a server program might handle a service called
"debit_credit". The key requirement is that the entire transaction,
including the "commit work", must be executed within a single service. This
is the restriction which XA will remove, as we'll see later. Each
server process can serially handle requests on behalf of different clients.
Because a server process can handle many client processes, this can
reduce the total number of active processes on the server system,
thereby reducing resource requirements and possibly increasing overall
throughput.
When Oracle is used with a TPM in this mode, we call it an Oracle-managed
transaction since the transaction commit or rollback is done with a SQL
statement.
What is XA? How does XA help Oracle7 work with UNIX TPMs?
XA is an industry standard interface between a Transaction Manager and a
Resource Manager. A Resource Manager (RM) is an agent which
controls a shared, recoverable resource; such a resource can be
returned to a consistent state after a failure. For example, Oracle7 Server
is an RM and uses its redo log and undo segments to be able to do this.
A Transaction Manager (TM) manages a transaction including the
commitment protocol and, when necessary, the recovery after a failure.
Normally, Oracle Server acts as its own TM and manages its own commitment
and recovery. However, using a standards-based TM allows Oracle7 to
cooperate with other heterogeneous RMs in a single transaction.
The commonly used TPMs include a TM component for this purpose. In order to
use the TM capability of the TPM rather than Oracle7's own transaction
management, the application uses a transaction demarcation API (called TX)
provided by the TPM rather than the SQL transaction control statements (e.g.
"commit work"). For each TX call, the TM then instructs all RMs, by the
appropriate XA commands, to follow the two-phase commit protocol. We
call this a TPM-managed transaction.
The following picture shows these interfaces within a monolithic application
program model. This is the model most commonly described in the
DTP literature. We'll see later what the picture looks like when we add
Oracle7 and when we switch to a modularized client-server application
program model.

     | Resource | | |<----->| Transaction |
     | Managers | |--- | Manager |
     | (RMs) | |<-------->| (TM) |
     | |--- | |
     | |<----------->| |
     ---------------------- XA --------------------
                    Interface
The XA interface is an interface between two system components, not
an application program interface; the application program does
not write XA calls nor need to know the details of this interface.
The TM cannot do transaction coordination without the assistance of
the RM; the XA interface is used to get that assistance.
How does the DTP Model support client-server?
The above picture was actually simplified to make it easier to explain
the role of XA. In a true distributed transaction architecture, there
are multiple applications, each with an Application Program, a Resource
Manager, and a Transaction Manager. The applications communicate by
using a Communication Resource Manager. The CRM is generally provided
as a component of the TPM. It includes the transaction information when
it sends messages between applications, so that both applications can
act of behalf of the same transaction. The following picture
illustrates this:
Client Application
| AP |
||| | |
SQL ||| | TX | CRM
||V V | API
-||-- ----- |
| |V | | | V
--|-- |<---| | -----
| V || | | | |

| | || | |XA+ | |
| | RMs |<-----| | -----
| | | XA | | A

| |
| |

/ |

/ |
Most TP Monitor products include both a TM and a CRM, and also provide
additional functions such as task scheduling and workload monitoring.
What is XA+? What does Oracle need to do to comply with it?
XA+ is an interface that lets the X/Open model actually be distributed
because it allows a communication resource manager to tell a TM on the
server that a message from a client just came in for a particular
transaction. Oracle is not currently planning to provide an X/Open
communication resource manager, so we don't have any plans right now
to do XA+. Version 2 of the DTP model paper from X/Open describes it.
The status of the current XA+ specification is "snapshot".
When would I choose an Oracle-managed transaction vs a TPM-managed
transaction?
Oracle Server is very efficient at managing its own transactions. If
the TPM manages the transaction, in general some additional overhead
will be incurred.
The two main reasons a customer might prefer to use a TPM-managed
transaction are as follows:
(1) He may need to update RMs from different vendors. Experience so far
has been that the most common case is wanting to update both Oracle and
a TP Monitor managed resource such as a transactional queuing service
in the same transaction (see Article 3).
(2) He may want to use the model of having several different services in
a transaction, even to the same database. For example, the
"debit_credit" service could be split into a "debit" service and a
"credit" service. This is a very attractive model, but this type of
modularity does exact a performance penalty (see Article 4).
Can I get a version of XA to run on Oracle Server version 6?
No, the XA functionality uses two underlying mechanisms in the Oracle
Server which are not available in version 6: two-phase commit and
session switching. The upi calls for these functions do not not exist
in version 6.
When would I use XA vs Oracle7 to coordinate all-Oracle distributed
transactions?
Generally speaking, Oracle Server should be used to coordinate all-Oracle
distributed transactions. The main reason for using XA to coordinate
transactions would be that you want to use the TP Monitor service-oriented
architecture. That is, you would like to construct an application built of
services and service requests in order to benefit from the modularity and
workload control such an environment provides.
TP Monitor Application Architecture
===================================
What might a TP Monitor application look like?
Most TPM applications will consist of two more more programs, where
there are front-end client programs which request services and back-end
server programs which provide services. In this case, the TPM supplies an
additional capability which is transactional communication. The client
describes the boundaries of the transaction, through the use of the TX API,
and the TPM relays that transaction information to each requested service.
The overall application structure generally looks like the following in the
client-server model. The "TP Monitor Services" box is not necessarily a
process. It could be one or more processes, or just libraries coordinating
through shared memory. Each client process and server process could be on
a different machine. Normally, the application server processes would be
connected to their Oracle Server processes using the IPC driver; the TPM
would be used to deliver messages between application client processes on
one machine and application server processes on another. However, the
application server processes could also be connected with the standard
Oracle SQL*Net to shadow processes on different machines. This might be
useful if one of the databases was on a machine which did not support TPMs.

Application client programs might be written in C and be linked with
TPM libraries. Alternatively, they could use a screen painter product.
Application server programs would be written in Pro*C or Pro*COBOL and
be linked with TPM libraries, the normal Oracle7 user-side libraries
and libxa.a. The Oracle7 Server process is the regular Oracle7 executable.
More complicated application architectures can also be constructed. Most of
the TPMs allow a server to become a client of another service, so you can
involve additional servers.
Could I use Oracle7's Multi Threaded Server as the SQL*Net connection in the
previous picture?
Yes, but that will not be needed in many cases. For example, both
application server processes in the previous picture could talk to a
single Oracle7 Server process through the Multi Threaded Server in the
previous picture. However, since the TPM architecture typically reduces
the number of server processes, the reduction in processes using Multi
Threaded Server may be less significant than in an architecture without
TPMs. If the application will use database links, however, then MTS will
be required.
How do I write an Oracle TP Monitor application?
The actual API used to talk to the TPM varies between vendors, so you need
to get the documentation from the vendor. However, all have a way to
indicate where a transaction begins and ends and a way to send a request
and receive a response from a client to a server. Some use an RPC model,
some use a pseudo-RPC model, and some use a send/receive model. The TX API
described earlier is a subset of the TPM API as defined by each of
the TPM providers.
The client program and server program might look something like the
following examples. We h (such as Tuxedo's

Insert data 32K into a column of type LONG using the oracle server side jdbc driver

Hi,
I need to insert data of more than 32k into a
column of type LONG.
I use the following code:
String s = "larger then 32K";
PreparedStatement pstmt = dbcon.prepareStatement(
"INSERT INTO TEST (LO) VALUES (?)");
pstmt.setCharacterStream(1, new StringReader(s), s.length());
pstmt.executeUpdate();
dbcon.commit();
If I use the "standard" oracle thin client driver from classes_12.zip ("jdbc:oracle:thin:@kn7:1521:kn7a") every thing is working fine. But if I use the oracle server side jdbc driver ("jdbc:default:connection:") I get the exception java.sql.SQLException:
Datasize larger then max. datasize for this type: oracle.jdbc.kprb.KprbDBStatement@50f4f46c
even if the string s exceeds a length of 32767 bytes.
I'm afraid it has something to do with the 32K limitation in PL/SQL but in fact we do not use any PL/SQL code in this case.
What can we do? Using LOB's is not an option because we have client software written in 3rd party 4gl language that is unable to handle LOB's.
Any idea would be appreciated.

Steps to Connect remote Oracle Server using OCi C in Linux

Hi !
I am trying to connect oracle server through my application using OCI C in linux, it works fine in my oracle server machine.
I want to connect oracle server through my C application from Oracle Client Machine
can anyone help me in this issue ?

Balaji.C

Sounds like you did not specify your database name. Or you database name is hard-coded.
Can you show us the code?
Is your TNSNAMES.ORA set up correctly?
Also, you did not specify any error messages or anything. Are you checking the result codes after any functions?

How to use oracle functions in Crystal Reports XI using Oracle Server

Hi all,
Is it possible to use oracle functions in Crystal Reports XI using Oracle Server as Data Source.
If i try to use a procedure,i am getting error with message "Invalid Arguement Provided".
Functions are not visible objects like tables,views and stored procedures.
The jdbs driver i m using is oracle.jdbc.driver.OracleDriver.

I think it is not possible to add functions in crystal directly for any database. You need to use those functions in a stored procedure and add that storedprocedure as a datasource.

Oracle raise ORA-03113 when connect to a remote oracle server using toad

Hi there,
when i use the tool toad connect to a remote oracle server which located in a different city,
when i submit a query in toad,
if the query returns many rows of data, it will raise the error ORA-03113：end-of-file on communication channel,
however if the query returns only a few rows, i won't raise such error,
however, when i use sqlplus connect to that remote server, it won't raise such error,
what's the reason is, can any one tell me how to tackle this problem if using the tool toad. thanks/

my oracle server is 2 nodes rac server,
and i've tried two different kind version of toad v9.6 and v10.5, and both have the same problem
once i query a table, if the result returned more than 30 rows, then it will raise that error, if query returns less than 30 rows, it's ok.
i assume it is a problem concern with network, but i don't know why no such error raise when using sqlplus ?

In Java,how can I get remote oracle server's system time using a XAOracle datasource

I want to get remote oracle server's system time,for example,I use a TxDataSource:
DRIVER className:weblogic.jdbc.oci.xa.XADataSource
URL:jdbc:weblogic:oracle:lanhaibo
JNDI Name:
the following is the code which shows the exception that: sqlexception:the JDBC2.0
method is not implemented,why? what should I do?:
Properties prop = new Properties();
prop.put(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContextFactory");
prop.put(Context.PROVIDER_URL,"t3://"+"localhost"+":" + "7001");
initCtx = new InitialContext(prop);
DataSource ds = (DataSource)initCtx.lookup(strDataSource);
Connection conn = ds.getConnection();
String sqlQuery = "select to_char(sysdate,'yyyy') YYYY,to_char(sysdate, 'MM')
MM,to_char(sysdate, '" +
"dd') DD,to_char(sysdate, 'hh24') HH,to_char(sysdate, 'mi') MI,to_char(sysdate,
'" +
"ss') SS from dual"
preparedStatement pstmt = conn.prepareStatement(sqlQury);
StringBuffer sb = new StringBuffer();
ResultSet resultset = pstmt.executeQuery();
if(rs.next()){
strYear = rs.getString("yyyy");
strMonth = rs.getString("MM");
strDay = rs.getString("DD");
strHour = rs.getString("HH");
strMinute = rs.getString("MI");
strSecond = rs.getString("SS");
sb.append(strYear);
sb.append("/");
sb.append(strMonth);
sb.append("/");
sb.append(strDay);
sb.append(" ");
sb.append(strHour);
sb.append(":");
sb.append(strMinute);
sb.append(":");
sb.append(strSecond);

Joden asked:
"I want to get a remote oracle server's time by XADataSource,
use:"select sysdate from dual", but return a null value,and give
the message"sqlexception the jdbc2.0 method is not implemented",
why?"
Let me see your code. A simple executeQuery() should do the trick:
Statement s = c.createStatement();
ResultSet r = s.executeQuery("select sysdate from dual");
while (r.next())
java.sql.Timestamp t = r.getTimestamp(1);

Hi.
I guess you are using weblogic.jdbc.oci.xa.XADataSource as a

Weblogic JDriver for Oracle "implementation" is really weak as a lot
of methods are not implemented.
This is why you get this message.
You may find the (very impressive) list of non implemented methods at
http://e-docs.bea.com/wls/docs70/oracle/API_joci.html#1162621 (sorry
HTML links don't seem to work here).
Any call to one of this methods will give you these nasty message and

Try to use the "official" Oracle JDBC driver XA Datasource
(oracle.jdbc.xa.client.OracleXADataSource) instead of Weblogic JDriver
for Oracle one's.

Automating Oracle Server Installation using response file

I am automating Oracle Server Installation using response file. No Installer page should be displayed, except 'Optional Config Tools' page at the end of the installation showing the list of optional configuration tools e.g Net Configuration Assistant, Database Configuration Assistant, and Intelligent Agent Configuration Assistant. All other pages would not be displayed.
My response file doesn't seem to work this way. During installation, it displays the 'Create Database' page asking whether you want Database Configuration Assistant to be automatically launched at the end of the installation for database creation. How do I prevent this page from displaying, while selecting default option (Yes) using response file?

Provide info about the OS you are using and Oracle version.

i think that oracle company should provide a common package,when i use non-oracle j2ee server,i can include them.
thank you!
