Oracle Rdb Driver 3.1.0.0 problem with blobs

I am trying to convert an MsAccess application to use an MsAccess front end and an Oracle Rdb back end.
I've created the test database under VMS and can successfully link to the Oracle Rdb tables from MSAccess 2000. One of the main reasons for converting to Oracle Rdb is to be able to store large word documents in the database. I was able to do that using Oracle rdb Driver v 3.00.02.06. I recently converted to Oracle Rdb Driver version 3.1.0.0 and can no longer access the Blob field containing the Word document. MsAccess now sees this field as type Binary and I keep getting an invalid field type error. (with 3.00.02.06 this field was seen by MsAccess as an Ole Object and the getchunk and appendchunk functions for getting and saving a blob worked reasonably well).
Is this a bug in 3.1.0.0 or is there some way to get MsAccess to recognize this Binary field type?

I suspect you'll need to contact Oracle support on this. There aren't, to my knowledge, any RDB folks around here.

Does multilingual work with Oracle oci8 Driver? I am facing problems with oci8 while thin driver works fine ...

Hi, I am currently working on iPlanet 6.0 SP4 with oracle 8.1.6. I am planning to make my application language independent. while testing I figured out that if i use oci8 driver or oracle, it doesn't support other language characters while the thin driver supports fine. Can anybody help me regarding this? Is this a bug, or some possible configuration issue? Has somebody came across this problem before? How do i go about it ?

We faced same issue. Looks like the native driver does not support the automatic data encoding/decoding from/to database. You can always workaround this by reading everything as byte stream and then by letting java handle the encoding/decoding. But we decided to use type4 thin driver which does this automatically if you set the content type. Anyway we are told that later versions of IAS may not support native drivers, so if you are serious about multi language shift to type4 thin drivers now itself.

Oracle RDB driver Version 3.01.00.01 Connectivity Issue

I have a SQL Server 2000 extended stored procedure connecting to an Oracle RDB data server via an ODBC connection (using Oracle RDB driver Version 3.01.00.01). The SQL Server 2000 runs on a Windows 2000 Server.
This extended stored procedure opens up multiple database connections and maintains them for processing. Usually, everything runs fine.
However, every so often, we have connectivity issues. What happens is as follows:
When we bring a station down and then try to reconnnect, our connection is denied, and we get the error: "recv() unexpected close Ret 0 Err#0 UNKNOWN Unknown WINSOCK Error 0". (This error is logged by the .dll running in the SQL Server processing space.) From the first time we receive a connectivity error like this until the Oracle RDB box is rebooted, we cannot establish another new ODBC connection to that Oracle RDB box --- whether we are trying to establish it programmatically or just via a "test connection" in the ODBC dialogue on the SQL Server box.
We can, however, establish an ODBC connection to another, identically configured, Oracle RDB box from the SQL Server box (without restarting the SQL Server box).
Has anyone had experience with instable connections from Windows system using the Oracle RDB driver to connect to the Oracle RDB? If not, can anyone point me in a direction that would help me research this? I am more familiar with SQL Server than Oracle, and the Oracle DBA on the other end isn't very accessible.
I'd really appreciate any help anyone can give me.
Thanks!

I got same error.. Are you already solve that problem? how? please help me. Thanks

Oracle RDB Driver fails with JDBC/ODBC Bridge

Has anyone experienced problems using the latest Oracle RDB
Driver (3.0.2.0) with the JDBC/ODBC Bridge.
We have been using the Oracle ODBC Driver for RDB (2.10.17)
successfully on NT, but it is not supported on W2K. The new
drivers work fine for Access etc., but fail with the bridge.
Specifically, you can step thru a result set, but getObject()
returns null for all fields.
Any suggestions?

Oracle RDB driver for java

hello.
i connect to my oracle driver using this
Class.forName("oracle.jdbc.driver.OracleDriver");
but now i have to use oracle RDB and i want to ask how that is done?
do i have to download another jar for that?
and how is the connection string done?
thanks

nope.
you're getting me all wrong
i already have ojdbc14.jar and i already connected to oracle 9iHow did you do that without knowing the connection string?
the problem is with oracle RDB jdbc
that's another different matter.What? I don't understand.
oracle rdb runs under open vms and you have to
install some other things before the rdb jar itself.I don't know about running Oracle on OpenVMS. Sorry.
and i also need the connections tring for the class.How did you "connect" without it?
I gave you a link to the docs, which should tell you what the connection string syntax is. It'll look something like this:
jdbc:oracle:thin:@host:1521:database%

Crystal Report Oracle ODBC driver invalid Thai character display problem

Hi,
   My server has CR Oracle ODBC 5.1 installed on last week. We have several reports in the servers which called by our Application to export to text file and pdf file. Sometimes, the output (both text file and pdf file) can't display Thai character correctly. The text file show Thai character in question mark and pdf file show in square box. This problem occur randomly and disappear without doing anything. Sometimes the problem occur for an hour and gone but sometimes occur 10-15 minutes and gone. This problem also not happen every days. Once the problem occur, all reports with Thai character will fail.
   However, we have another server installed the same Application, same OS level, same OS patches and same CR Oracle ODBC driver version installed on the same time as above server (the problem server). This server does not have any problems.
   Any suggestions would be appreciated.
Best Regards,
Noppadon S.

Hi Noppadon,
Thank you for the info. If it happens randomly in their application then it's something they need to debug. Could even be in the ODBC driver.
I suggest you tell them that because it works sometimes it shows the issue is likely in their software because if it failed all the time then it would be in Crystal dll's. They need to debug the problem, suggest they use tools like Process Monitor from www.sysinternals.com to step through to see where or what part is failing. If they having logging abilities that may help to find out what step is failing and in which API.
At this point we have no way of determining where the problem is, it's failing in their application and no one but them know what or how they are using CR runtime files.
If you can duplicate the problem using Crystal Report Designer then it's our problem, if not they have to help you to show us it is a CR issue.
Sorry we can't be of more help but without know their code we can't suggest anything to try. Suggest they log a call with support here to help them debug the problem if they don't know what to do.
Thank you
Don

Problem with blob column index created using Oracle Text.

Hi,
I'm running Oracle Database 10g 10.2.0.1.0 standard edition one, on windows server 2003 R2 x64.
I have a table with a blob column which contains pdf document.
Then, I create an index using the following script so that I can do fulltext search using Oracle Text.
CREATE INDEX DMCS.T_DMCS_FILE_DF_FILE_IDX ON DMCS.T_DMCS_FILE
(DF_FILE)
INDEXTYPE IS CTXSYS.CONTEXT
PARAMETERS('DATASTORE CTXSYS.DEFAULT_DATASTORE');
However, the index is not searchable and I check the following tables created by database for my index and found them to be empty as well !!
DR$T_DMCS_FILE_DF_FILE_IDX$I
DR$T_DMCS_FILE_DF_FILE_IDX$K
DR$T_DMCS_FILE_DF_FILE_IDX$N
DR$T_DMCS_FILE_DF_FILE_IDX$R
I wonder what's wrong with it.
My user has been granted the ctx_app role and I have other tables that store plain text which I use Oracle Text are fine. I even output the blob column and save as pdf file and they are fine.
However the database seems like not indexing my blob column although the index can be created without error.
Please advise.
Really appreciate anyone who can help.
Thank you.

The situation is I have already loaded a few pdf document into the table's blob column.
After I create the Oracle text index on this blob column, I find the system generated index tables listed in my earlier posting are empty, except for the 4th table.
Normally we'll see words inside the table where those are the words indexed by oracle text on my document.
As a result, no matter how i search for the index using select statement with contains operator, it will not give me any result.
I feel weird why the blob is not indexed. The content of the blob are actually valid because I tested this by export the content back to pdf and I can still view and search within the pdf.
Regards,
Jap.

Problem with BLOB data type and acute characters

Hi all, I have an issue related with BLOBS cols:
I have table A with a BLOB column and I need to insert that data into another table B, the thing is I use dbms_lob.read() that returns data into a RAW variable and then I convert it to a varchar2(with utl_raw.cast_to_varchar2) and it works ok if I have no "acute characters" on it, e.g Québec.
If I have acute characters, the "é" is inserted wrongly with an "¿" character on the table B. I tested the BLOB on the table A to check the data and the BLOB is showing correctly the "é" character, it seems that the dbms_lob.read() funct cannot handle accute characters and replace them with "¿".
How can I replace acute characters when I use the dbms_lob.read functionality?
Thank you!

That appears to be a bug in the console. You might try the command-line tool java weblogic.Deployer for deploying apps. java weblogic.Deployer -examples will give detailed usage info.

Oracle VM 3.2.1 test setup - problems with OVS node evictions

Hi all
I am building a small test environment for Oracle VM with the following configuration
4 boxes, each 1 x AMD 6 core cpu + 32GB RAM + 2 x 1GB ethernet (10.30.32.n, 192.168.20.n networks - I only have 1x16 port GB switch, so all cabling is through the one switch - that may be part of the problem)
3 boxes are diskless, running Oracle VM Server from 8GB USB flash drive
1 Box is EL6.3 and set up with:
1x750GB with (LVM) partitions for /, /u01 (Oracle 11gR2SE + OVM Manager), swap, and a partition for the OVS pool
4x2TB drives, set up with LVM striping, and 4 LVs - 1 750GB for virtualbox and VMWare VMs, and 3 others for OVS storage repositories (each a bit over 2TB) - all ext4.
The OVS Pool and OVS Storage file systems are exported via NFS
VM server and VM manager installs all went smoothly. Servers and storage are discovered OK in the manager.
I created 2 networks - one on the 10.30.32 subnet for Server Management, Cluster Heartbeat and Live Migrate (also the public network for accessing the machines). The other on the 192.168.20 subnet for Storage and Virtual Machine.
Created storage pools, and presented to all the servers.
In creating the Server Pool, just took the default 120 for the cluster timeout
Now when I try to import an assembly, or a VM template, it gets so far, then then the server doing the actual job reboots.
My initial thought is that for whatever reason the NFS traffic involved in importing and writing - either network, or I/O on the NFS server - is swamping the cluster heartbeat traffic, and the node just fences itself
Just wondering if anyone has any ideas or suggestions, or can advise what further diagnostics or troubleshooting I can do

I suspect it more to do with your storage than anything. Run your import again and sample your I/O performance from your NFS server during the import. Also, if you can... .create LACP bond on your NFS server. I don't know what kind of throughput you expect but remember. A single GB nic can only do a max of 125/MB a sec. That sounds rather good but take into consideration everything you're doing across your environment... its not a lot. I see well over 400 mb/sec network throughput at times on my storage. I run bonded 10GB nics.
Once you get your templates and such built you shouldn't experience that much NFS I/O. You should allocate enough memory to your guest as to avoid virtual disk paging on your NFS storage.

Using an NAS drive as the iTunes library (problem with Lacie external hd)

Hi,
I already have my iTunes library on an external hard drive (LaCie 320GB mini Hard Drive & Hub) which I absolutely NOT recommend. The drive goes in sleep mode every now and then and most of the time I have this big 4 sec blank between each song till the drive wakes up again
soooo painful.
Anyway, I am about to buy another external hard drive with an Ethernet interface (+ FTP and samba) Does anyone know a good product? Any problem running the iTunes library over the Ethernet network?
By any chance, if someone know a trick to cut the sleep mode of my external hard drive, that would be great as well.
Thanks!

Alexis, saw your mention of trying to put the iTunes library file on the network, and wondered if you would comment further on why you wanted to do that, and what happened to make it difficult. It sounds like what I'm trying to do.
I have all my music on a USB disk attached to my Airport Extreme base station. I have three Macs in the house - two on a 1G EtherNet and one MacBook on wifi. I would like to have each instance of iTunes use a common library, so that I can access my music from any of the three Macs. It seems that putting the Library file on the networked drive would do what I need, after telling iTunes on each Mac to use that library. Yes? No? Definite maybe? I'd appreciate any information you would share.

Oracle Database XE - apex on Windows 7 - Problem with Connection from another Windows 7 Computer

Hello,
I started with Oracle Database XE 11g, with apex, did the upgrade to Apex 4.2.6 and started in developing a small Application.
I wanted to Connect to my Computer A (with Database runing on it) from another Windows 7 Computer B.
So I put in in Firefox: //A:8080/apex but I only received a timeout.
Of course on both Computers there is a windows-Firewall running, so I stopped on both Systems the Firewall, but its the same still.
In the windows explorer running on Computer B , I can see the data of Computer A and both Computers are in the same home-net-group. (sorry for my poor english).
Is there anyone who cann tell me how to get the Connection running ?
Maybe I didn't see the info about this in the manuals, if it is there, please give me a hint.
many thanks

JDBC performance problem with Blob

Hi,
I've some performance problem while inserting Blob in an Oracle
8i database. I'm using JVM 1.17 on HP-UX 11.0 with Oracle thin
client
The table I used contains only two columns : an integer (the
primary key) and a blob.
First I insert a row in the table with an empty_blob()
Then I select back this row to get the blob
and finally I fill in the blob with the data.
But it takes an average 4.5 seconds to insert a blob of 47 Kb.
Am I doing something wrong?
Any suggestion or hint will be welcome.
Thanks in advance
