Problems storing CLOBs with build-in Oracle 8.1.6 thin driver of WebLogic 6.0 SP2

Hi,
I'm using the build-in Oracle 8.1.6 thin driver that comes with
weblogic.jar of WebLogic 6.0 SP2. It doesn't store CLOBs. Here I have
to use the class weblogic.jdbc.common.OracleClob. Why?
WebLogic 5.1 SP 9 + Oracle 8.1.6 thin driver (external) does. Here I
use the class oracle.sql.CLOB.
Must I use a OCI driver?
Thanks,
Juergen

I'd also recommend to switch to 8.1.7 thin driver. It's more stable.
Regards,
Slava Imeshev

You can use thin driver to persist CLOB. One thing you must be sure to setautocommit
to false. Hope this help.

Memory leak in weblogic 6.0 sp2 oracle 8.1.7 thin driver

Hi,
     I have a simple client that opens a database connection, selects from
a table containing five rows of data (with four columns in each row)

Repost in JDBC section ... very serious issue but it may be due to Oracle or
to WL ... does it happen if you test inside WL itself?
How many iterations does it take to blow? How long? Does changing to a
different driver (maybe Cloudscape) have the same result?

WebLogic 5.1.0 & Oracle 8.1.7 thin driver for jdk 1.3.1

We're currently using Oracle 8.1.6, and need to upgrade to 8.1.7.
Platform: Solaris 2.6
WebLogic: 5.1 Service Pack 9
JDK : 1.3.1
Regarding the thin drivers, my understanding is that w/ 8.1.7, we can use either
8.1.7 OR 9.0.1 thin drivers. Has anyone seen issues using either thin driver
w/ Oracle 8.1.7 and WebLogic?
Thanks in advance!

Regarding the thin drivers, my understanding is that w/ 8.1.7, we can use either
8.1.7 OR 9.0.1 thin drivers. Has anyone seen issues using either thin driver
w/ Oracle 8.1.7 and WebLogic?Chad,
We've used both thin drivers successfully under WebLogic 5.1, and
have been using the 9.0.1 thin driver under Weblogic 6.1 without any
problems. We moved to the 9.0.1 driver because it's the first driver
version to implement
PreparedStatement.setTimestamp(Timestamp,Calendar).
Recently, we started looking at using JMS and may need to use
distributed
transactions, and we're concerned about transaction support in the
thin
driver. Various WebLogic docs, like
http://e-docs.bea.com/wls/docs61///notes/issues.html#1048698, mention
that 8.1.7 has XA threading issues that cause problems in distributed
transactions. In one place, they mention that they may have a
workaround, but it's unclear what the status of that is. And it looks
like they definitely haven't gotten to testing
the 9.0.1 driver. If you're interested in distributed transactions,
you might want to investigate that first.

Oracle 8.1.7 Thin Driver Resultsets

A simple question I hope.
We are using the Oracle 8.1.7 thin driver to connect Weblogic 6.0sp2 to an Oracle
8 db. My question is regarding how the resultset is passed to the server. Is
there cacheing? If so, is the cache recycled..i.e. for a 1000 row set are rows
fed to the server 100 at a time? Or is the entire resultset passed at once.
A general description of this transation or pointers to documentation would be
greatly appreciated. Thanks for your consideration,
Jason

JasonHi. This is entirely an oracle DBMS and driver question. From what I can glean from
oracle documentation, there is a settable driver property which sets how many rows
the driver gets in one request. This implies the DBMS and driver will cooperate to
get a given result set in chunks.

SSRS 2008 Using Stored Procedure with SysRef Cursor Oracle

Hi,
I am new to SSRS.
I have a ssrs procedure which runs to Return Result of Select Query. ( In form of SYS REF Cursor in Oracle ).
When I am trying to see the Value in Test Window. It is showing Output. But when I m Running the Report in the environment it is giving me error.
Please help me if there is a better way of handling it.
As I read in some forum as SSRS has issue handling SYS Ref Cursor...
Thanks
Priyank
Thanks Priyank Piyush

Hi Priyank,
According to your description, you are use a Stored Procedure from SysRef Cursor Oracle as the report dataset. The query works well in Dataset Query Designer, while an error occurs when you render the report.
As per my understanding, the problem is that there are something wrong with the report design. Please double-check the design of the report. In order to trouble shoot the problem more efficiently, could you please post the detail error message? Then we can
make further analysis.

Using oracle thin driver from Weblogic server 6.1

Hi
I need to know which driver is best for establishing JDBC Connection i.e.
whether to use JDriver provided with Weblogic or to go using Oracle thin driver.
Can some one tell the detailed procedure involved in configuring oracle thin driver
in Weblogicserver 6.1.
Thanks in advance,
S Gopikrishna

I would recommend using the thin driver where ever possible, their are
certain problems with thin driver which are more in the area of XA support
you can check weblogic documentation for pointers on this. Oracles latest
thin driver is pretty stable as they have fixed a bunch of problems.
heres how to use thin driver:
create the connection pool using the following url
jdbc:oracle:thin:@<mc-name or ip-address>:<port-no>:<oracle sid>
and driver: oracle.jdbc.driver.OracleDriver
You dont have to install the thin driver its bundled with the product.

How can I do "2PC" WLS6.0 + oracle 8.1.6 (thin driver )

Access oracle db by sys user and execute initjvm.sql and initxa.sql.
And then grant "select" priviledge on dba_pending_transactions to users that you
want to use to make dbpool.

Oracle proxy authetication and thin driver

Hello,
I am using 10g, and bea 81 sp3, I am trying to setup proxy authetication. All the references I find for proxy authetication are using OCI driver. Is proxy authetication supported using oracle 10g thin driver (ojdbc14.jar)? Can anyone tell me, what drivers are support proxy authetication under oracle 10g?
Also application servers like bea will not give you oracledata source if you use bea to setup oracle connection pool, is there a easy work around that?
appreciate,

At the time our issue was resolved, the bug was not published. And, I was told, there was no information in metalink about the isue. I am not sure whether they published some thing in the last few weeks.
This is what resolved our issue.
Step 1: alter system set java_jit_enabled=FALSE;
Step 2: Try your test case. If it is the same issue as ours, your test case will be successful. If it succeeds, Go to step 3. If it does not succeed, it is a different issue.
Step 3: alter system set java_jit_enabled=TRUE;
Step 4: Run your test case. If it is the same issue, it is expected to fail. Go to Step 5 in case of failure.
Step 5: Delete all rows from table java$mc$
Step 6: Restart the database
Step 7: Run your test case. It is expected to be successful.

Problem storing properties with IServiceProfile

Hi SDN,
I found the following SDN Topic which seems to be similiar to my problem:
https://forums.sdn.sap.com/thread.jspa?forumID=41&threadID=26137&messageID=233589#233589
I feel I have the same problem but not on EP6 SP3 but on current EP6 (tested on SPS12 and SPS14). So I decided to open this as a new topic again:
I have a service for which I am trying to set properties programmatically.
I created an iView which calls a set method on the service. In this method a specific property of the service is changed using the following code:
IServiceProfile serviceProfile= context.getServiceProfile();
serviceProfile.setProperty(key, value);
serviceProfile.store();
However, if I look in the Property Editor of this service sometimes this call seems to change the property and sometimes not!
Specifically, if I use the call above just after restarting the SAP EP it works. But any following call does not change the value in the Property Editor.
If I check the value bevor changing it in the iView which does the change it seems like the property value has been changed correctly.
But it is not a caching problem in the browser, because if I access the property from a different iView it has not changed as well.
Does anybody know about a solution to this problem?
Best regards,
Stefan Brauneis

Hi Detlev,
I was hoping that anybody could find a better solution than telling "...ask the expert next door...".
But this answer is of course more valuable than nothing. So you get points. Sorry, I could have done this earlier.
The problem, however, still exists. Even if it has only very low priority for me, because there is the workaround of just using the services property editor. Every change there seems to be reflected immediately.
I will keep this question open and wait if somebody on SDN has a solution to it.
Best regards,
Stefan Brauneis

Oracle 8.1.6 Thin Driver with Multiple Result Sets

We're using Oracle 8.1.6 on NT using the latest driver release.
Java 1.2.2
We're experiencing problems with resultSet.next when we have multiple result sets open. What appears to be happening when you've read the last result set entry do a .next() call which should result in a false value we actually get java.sql.SQLException: ORA-01002: fetch out of sequence.
This seems to us that the driver is trying to go beyond the end of the result set.
We've checked JDBC standards (and examples on this site) and the code we've got is compliant. We've also found that the code produces the correct results under Oracle 7.3.4 and 8.0.4.
I can also say that there is no other activity on the db, so there are no issues such as roll back segments coming into play.
Any solutions, help, advice etc would be gratefully appreciated!
null

Phil,
By "multiple result sets open", do you mean you are using REF Cursors, or do you have multiple statements opened, each with its own ResultSet? If you could post an example showing what the problem is, that would be very helpful.
You don't happen to have 'for update' clause in your SQL statement, do you?
Thanks

I had already created the ssl-jdbc connections for Weblogic 9.2 with Oracle 10.2.0.3.0 based on the documents above.
My questions
1. the connections are not using the desired ports. The TCP listener is using 1521, and TCPS listener is using 1522, and 2484. However the connections do not use the configured ports. Is it normal?
2. If using the unassigned port is the normal case, where can I limit the port range?
3. How to prove the connections are in SSL?

3. How to prove the connections are in SSL? No idea, too.
