Problems using Oracle or MSSql DBMS with Weblogic 5.1 SP6

We have installed Weblogic 5.1 with service pack 6 on NT 4.0.
The database access works fine with the default Cloudscape,
but when we try to use the SQL scripts for Oracle supplied by BEA,
we keep getting rollbacks.
We have also tried to modify the SQL scripts to access a MSSQL 7
database,
and we get the same kind of problems.
Can anybody help ?
Thanx.

I guess SQL syntax for cloudscape may not be same as Oracle. Pls check
cloudscape manuals.
Also you are talking about rollbacks. Could you be more specific.?
Pls post full stack trace here.

Problems using 4096 bit SSL certificate with WebLogic Apache 2.2 plug-in

Hi,
'm using WebLogic 9.2 MP3 and Apache HTTP Server (version 2.2) Plug-In. For security reasons, I have SSL installed on both Apache and WebLogic. So Apache must communicate with WebLogic via https.
I get the following error when attempting to access WebLogic via Apache:
Internet Explorer cannot display the webpage
These are the last lines in wlproxy log:
Fri Feb 26 14:08:59 2010 <71212672221392> INFO: SSL is configured
Fri Feb 26 14:08:59 2010 <71212672221392> SSL Main Context not set. Calling InitSSL
Fri Feb 26 14:08:59 2010 <71212672221331> INFO: Initializing SSL library
I've found that the problem is caused by using a 4096 bit intermediate cert. When I include this 4096 bit cert in the file referenced by plugin parameter "TrustedCAFile", it is unable to load it. I've tested 4096 bit certs from a few different certificate authorities, and consistently see this problem, so I know the problem is not related to the specific certificate. If I use a 2048 bit intermediate certificate, everything works perfectly fine.
Do you know if there are limitations to the certificate length that the plug-in can use?

Yes 4096 bit Certificates are not supported by the plugin.
You can use up to 2048 bit.
There is a Bug which clearly mentions it.
I dont remember the Bug Number, but an Oracle Support person will be able to tell you.
Hope this helps.

ORA-01002: fetch out of sequence error when using Oracle Thin Driver 9i with Weblogic 6.1

The simple program below is a client that executes a SELECT query -
there are 13 rows in the table, of which 10 are printed when I run the
program, then after that the ORA-01002 error is reported. I am not
doing anything with LOBs, or updates. I've tried putting
con.setAutoCommit(false) as well, but that does not do anything.
Why am I getting this error? Can anyone help.
Thanks

Thanks everybody.
I have tried this, calling ut.begin() first before getConnection,
however no difference. However the problem goes away if I call
stmt.setFetchSize(100);
But I would prefer not to have to code this in every time!!!
I see there is a setting within Weblogic Admin console to see the
row-prefetch, but that is already set to 45 rows, so why do have to
explicitly call stmt.setFetchSize(100)!!!
Thanks

"Carl Lawstuen" <[email protected]> wrote in message news:<[email protected]>...
Agreed. The transaction must start before the connection. This is what
is most likely causing the error.
"Nils Winkler" <[email protected]> wrote in message

Hi,
one more thing: The UserTransaction has to be started before you obtain
the connection, not after.

Is there any known problem using Oracle SQL Developer 3.0.04 with Java 1.7?

I'm new to Oracle. I have installed Oracle SQL Developer 3.0.04 and Java 1.7. When I run Oracle SQL Developer, I will get the window Running this product is supported with minimum Java version of 1.6.0_04 and a maximum version less than 1.7. This product will not be supported....
Is there any known problem using Oracle SQL Developer 3.0.04 with Java 1.7?
I have already downloaded Java 1.6 but don't know whether I need to uninstall Java 1.7 first. If don't need to uninstall Java 1.7, how can I set Oracle SQL Developer to run with Java 1.6?
Thanks for any help.

Hi,
One prior post discussing the use of Java 7 is:
SQL Developer 3.0 and Java SE 7?
There is no need to uninstall any Java version (except if you have disk space constraints) and no problem switching between Java versions. This may be controlled in the sqldeveloper.conf file in your ...\sqldeveloper\sqldeveloper\bin directory via the SetJavaHome line. For example:
#SetJavaHome ../../jdk
SetJavaHome C:/Program Files/Java/jdk1.6.0_26
#SetJavaHome C:/Program Files/Java/jdk1.7.0Regards,

Creating my Oracle connection works fine ... code as follows:
Context ctxt = getInitialContext();
DataSource dataSource = (DataSource) ctxt.lookup(poolName);
Connection conn = dataSource.getConnection();
OracleConnection oracleConn = (OracleConnection)((WLConnection)conn).getVendorConnection();
I also have reviewed documentation:
http://e-docs.bea.com/wls/docs81/jdbc/thirdparty.html. In section 'Using OracleStruct Extension Methods' it highlights that
java.sql.Struct struct =(weblogic.jdbc.vendor.oracle.OracleStruct)(rs.getObject(2));
None of the documentation actually mentions oracle.sql.STRUCT. For Weblogic to truely provide support for Oracle it needs an easy way of converting to this data type. At present I cannot interact with Oracle APIs until I can create an oracle.sql.STRUCT.

Problems using Sony ECM DS70P Microphone with Vado HD 3rd gen

Problems using Sony ECM DS70P Microphone with Vado HD 3rd genXHello.
I have just purchased a Vado HD 3rd gen & was looking forward to using my Sony ECM DS70p Microphone,but after a couple of tests, the recording is extremely low & barley laudable.
The Microphone works fine on My Kodak Zi8.
Is there an internal setting I have to adjust, or is there a fault with the Vado
The Sony ECM DS70pMicrophone can be clearly seen in use here on a official Creative video.
http://www.youtube.com/watchv=oixLDAmc5qw
If anybody can offer some help or advice please, I would be very grateful.
Does anyone have a suggestion for a low profile stereo mic, to use with the Vado 3rd Gen
Thank you.
Thank you.

This is happening to me too, I don't know if this is an Adobe Flash Player 11.5's bug or it's just my computer. All my browsers, chrome, IE9, Fox, doesn't even load anime videos. I tried reinstalling 11.5 many times, it have no effect but I use IE9 64-bit to run the videos that couldn't run. I waited 25 min for a JW player to load an episode of anime and I'm sick of it.

Problems using Oracle Directory

Hi all
I have the following problem using 9i: I would like to use oracle internet directory to register my db's. I am currently reading the online handbooks and found a section that says to start the directory by using the 'oidmon' and 'oidctl' commands. The problem is that I cannot find these tools anywhere on the server, altough i am pretty sure i intalled anything important. is this a separate product? I thought it was included in 9i 9.2?
Anyone?
Cheers,
Michael

Hi.
Hmm, your shared lib path appears to be ok. What version of Solaris are you running? Also what JDK version are you using (I'll assume you are using the one that installed with WLS)?
You might also try posting this to the weblogic.developer.interest.jdbc newsgroup.
Thanks,
Michael

Which version of oracle thin driver are you using? Oracle 920 thin driver has some issues.
Thanks,

Actually there are 5 connection intialized but no connection is there in active pool.Sometimes when I
go to weblogic console and refresh the connection comes alive temporarily.Can anyone help me out for
fixing this problem

and what will be the price.. per licencse when i go to just purchase Oracle BPEL process manager

MAke sure you have not set ANY environment variable related to Oracle / BEA / Java / LD_library path. Use the following script to unset / set the initial settings:
#!/bin/sh
unset ORACLE_BASE ORACLE_HOME ORACLE_SID ORACLE_TERM
unset LD_LIBRARY_PATH LD_LIBRARY_PATH_64
unset CLASSPATH JAVA_HOME
export PATH=.:/usr/sbin:/usr/bin:/usr/local/bin:/opt/VRTS/bin
export BEA_HOME=/appl/oracle/products/9.2/weblogic

Using StoneBeat WebCluster load balancing with WebLogic

          Hi,
          I have done some testing of WebLogic Server with my company's StoneBeat WebCluster
          distributed load balancing software. This might be one more option to consider
          as a load balancing solution for WLS. It is advanced in the sense that load balancing
          is really dynamic, there are no single-points of failure (distributed architecture)
          and there is a very good, configurable test subsystem that runs on each cluster
          node to check for overload situations, HW/OS failures, ...
          In the initial testing, the WebCluster load balancing works with WebLogic replication,
          although there are some cases that need mroe consideration (please see below).
          I had to get a patch to WLS6SP1 on NT to make WLS' multicast work when there are
          several NICs on the cluster nodes.
          However, there is one case which causes problems:
          - I have 3 cluster nodes
          - P: 2, S: 3 (SessionServlet = 1)
          - 2: offline - P: 3, S: 1 (SessionServlet = 2; WebCluster randomly selected a
          new node to handle the connection)
          - 2: online - P: 2, S: ? (SessionServlet = 3, WebCluster redistributes the load
          when a node goes online)
          - 2: offline
          - P: 3, S: 1 (__SessionServlet = 1__) NB!
          The log messages show that when node 2 comes back online it retrieves the replica
          from the secondary (node 1) and not from the primary (node 3). After a while (5-6
          minutes), node 3 tries to update the replica on node 1. Node 1 considers this
          a stale update request and removes the Primary 16... (node name) and then the
          secondary for 16... (the replicated object). Then there's a message (still on
          node 1) that it is unable to find object 16... Back on node 3 the primary for
          16... is removed.
          From the WLS6 documentation (under the discussion of using replication with external
          HW load balancing solutions) I thought that this case would have been handled:
          - it is stated that after the failure of a node, if the HWLB box sends the next
          request to a node where there is no replica, WLS is able to retrieve the replica
          - to be fair, this is what happens: when node 2 came back online, it retrieved
          the replica from node 1 (the secondary) - I suppose that there is an assumption
          that if a request arrives to a node without a replica, the primary __must have
          failed__
          Is there any way to get around this problem?
          Admittedly, WebCluster has a problem in that the stickyness of connections is
          not perfect: - when a node goes online, a connection that was correctly persisted
          (based on either source-ip or source-network address) may be moved to a new node
          since the load is redistributed. Our load balancing is very dynamic, but doesn't
          maintain a list of who is connected to which node when resistribution takes place
          Regards,

Rick,
You may want to look at the Alteon and F5 configuration we have on edocs.
Take a look at the following URLs for a possible solution

Problem using oracle.dataaccess.dll

Hi,
I have an web application which uses Oracle.DataAccess.dll to communicate with and Oracle db. The web application deployed on 32 bit windows system works but not on windows server 2008 64 bit. I installed 10204_vista_win2k8_x64_production_db package, referenced the installed dll (version 2.102.4.0) from the project but I get the following error:
Could not load file or assembly 'Oracle.DataAccess, Version=2.102.4.0, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. The system cannot find the file specified.
Any help is appreciated. Thanks in advance.

I had this problem too.
I have not found any way to get ODP to work on a 64 bit machine. I have gone through more than 30 permutations of install combinations and all have their problems.
Your's is one I remember.
The error message does not give a good description of the problem. It CAN find it, but it can't load it.
The main problem in my opinion is that Visual Studio is a 32 bit app and so are its tools. MS will say that is no big deal because they don't want to rewrite native code sooner than they have too. It is going to stay that way for 2010. Visual Studio is going to load a .dll to connect to Oracle in server explorer and in any datasets you have created with the designer...its going to use a 32 bit .dll now your application wants a 64bit .dll... see the problem? I beleive that when you install the ODP registry settings are made for viual studios sake, but I don't know what happens under the hood.
Does visual studio give you any option at all to choose what assemblies to use for the IDE tools? nope
I have tried 32 bit client, 64 bit client, ODACwithODP and every combination of them in every version oracle offers on their download site. Nothing worked 100%.
I got
1) "cannot load file x" when x is at the specified path
2) BadImageFormat exception
3) App worked but visual studio tools crashed the IDE
4) installed all 3, but used the old system.data.oracleclient and tools worked sluggish or crashed.
You can also combine the problem of Oracle provider along with the fact that 1/2 of Visual Studio's tools don't care about 64 bit programming. For example, I made a wcf service that as going to access my database. Well, guess what you can't use Visual Studio's WCF debugger because WcfSvcost.exe is 32 bit. Will it give you an informative error message? nope. Just a BadImageFormat Exception with no clue which file is causing the problem. spent a week of precious time on that one and thought it was an oracle provider issue.
I have given up using ODP for now and am forced to use (4) System.Data.OracleClient just for the sake of getting any coding done at all instead of hacking my environment. It sucks. I got that working by installing 11r2 64 bit client in one home and 11r2 64bit client in another, then ODP in a 3rd. That way I can still use more friendly tools made for Oracle and let VS use the 32 bit client with the old System.Data.OracleClient dll.
If anyone has the magic step but step to get both a working IDE with its tools remaining functional along with a working application on Windows 7 64bit, than please please let me know!
