HI i have macbook pro with OSX 10.8. I am facing typical problem with Wi- Fi , in school wi-fi it does'nt connects to http sites and connects only https as no security/proxy settings done but in home wi-fi it connects to all http and https sites. How to fix this problem as I am new this operating system. Please any one help me in this as I have installed Delicious Library which is not working in school becoz it searches amzon http site.

I would imagine that at school, you're required to connect through an HTTP proxy.
From the menu bar, select
 ▹ System Preferences ▹ Network
If the preference pane is locked, click the lock icon in the lower left corner and enter your password to unlock it. Then click the Advanced button and select the Proxies tab. Enter the proxy settings given to you by the network administrator. Click OK and then Apply.
You may wish to create separate network locations for home and school. See the built-in help for instructions.

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!

what's the OS of the db server? is this code an anonymous pl/sql block, or stored pl/sql? does it run on the server or a client? if it's on the client, what's the o/s of the client?

Weird Problem with BLOB CMP field

Hi,
I am trying to deploy an EJB2.0 CMP Bean in Weblogic6.1 .The Bean has one of the CMP Field as a serializable object mapped to a BLOB Datatype in Oracle8i
When i try to creae this Entity Bean
I get "java.io.IOException: ORA-22920: row containing the LOB value is not locked" as a nested exception.
When i increased the isolation level . I got "java.io.IOException: ORA-01002 fetch out of sequence" as the nested exception
And one more horrible thing that is happening is the other arguments to the create method are getting updated in the DB except the Blob field(Supposed to rollback? when there is an EJB Exception ??)
Any thoughts? Comments?
Regards
Sathya

Hi,
I seem to recall that there are multiple issues with BLOBS & WLS. I'll describe my setup, and you can see if your missing anything:
- In weblogic-cmp-rdbms-jar.xml you need to set the column type as a Blob:
<field-map>
<cmp-field>binary</cmp-field>
<dbms-column>binary</dbms-column>
<dbms-column-type>OracleBlob</dbms-column-type>
</field-map>
- In weblogic-ejb-jar.xml you may need to set the isolation level of your set method:
<transaction-isolation>
<isolation-level>TRANSACTION_READ_COMMITTED_FOR_UPDATE</isolation-level>
<method>
<ejb-name>TerminalSoftwareKernelBDO</ejb-name>
<method-name>setBinary</method-name>
</method>
</transaction-isolation>
- The bean get/set methods should look like this:
public abstract void setBinary(java.lang.Object binary);
public abstract java.lang.Object getBinary();
- In WLS 6.1 up to Service Pack 2 (I don't know about SP3 yet), BLOBs are incorrectly implemented. For some (odd) reason you can only put serialized objects into the DB... I think this means that if you have a BLOB put in by anything but WLS, WLS get very unhappy. So empty out your table with the blobs first.
Hope that helps.

Problem with blobs larger than (about) 2kb

Hello,
I try to insert binary files with java (jdbc) into tables in my 9i database, and small files with e.g. 500bytes are no problem, but files with 3 or more kbytes are not inserted yet. I got no sql-exception. It simply seems not written into my table.
This is the SQL I used to create the table:
create table tblblob2 (
name varchar2(30),
content blob)
lob (content) store as glob_store (
tablespace LOBSPACE_1
storage (initial 100k next 100k pctincrease 0)
chunk 4
pctversion 10
INDEX glob_index (
tablespace raw_index))
TABLESPACE LOBSPACE_1
storage (initial 1m next 1m pctincrease 0);
insert into tblblob2 (name) values ('Test')
Before this I already tried a very simple create-statement, but it wouldnt work ,too. Thats why I tried this lob...
And then I used java to update this row:
DbConnectionHandling dbConnection = new DbConnectionHandling();
          dbConnection.connect();
          FileInputStream fis = null;
          Connection cn = dbConnection.connection;
          PreparedStatement st = null;
          try {
          File fl = new File( FILE ); // imgFile
          fis = new FileInputStream( fl );
          st = cn.prepareStatement( "update tblblob2 set content = ? where (name = 'Test')" );
          st.setBinaryStream( 1, fis, (int)fl.length() ); // imgFile
          st.executeUpdate();
          System.out.println( fl.length() + " Bytes successfully loaded." );
          } catch( SQLException ex ) {
               System.out.println("0: " + ex.getMessage());
          } catch( IOException ex ) {
               System.out.println("0: " + ex.getMessage());
          } finally {
          try {
               if( null != st ) st.close();
          } catch( Exception ex ) {
               System.out.println("1: " + ex.getMessage());
          try {
               if( null != cn ) cn.close();
          } catch( Exception ex ) {
               System.out.println("2: " + ex.getMessage());
          try {
               if( null != fis ) fis.close();
          } catch( Exception ex ) {
               System.out.println("3: " + ex.getMessage());
With small files it works, but whats wrong with "larger" files?
I need fast help...
Thanks, Nick

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

the thin drivers currently use the package "dbms_lob" behind the

there also is a 32k limit on pl/sql stored procedures/functions

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.

Problem with Blob key legnth in MySQL & JBoss

Hi,
I am using MySQL 3.23.55, JBOSS 3.0.6, EJB 2.0, CMP 2.0
I have configured the database, the tables are created but it stops at one place.In the type mappings-mappings , i have the following in the standardjbosscmp-jdbc.xml
java-type jdbc-type sql-type
java.lang.Object Blob LongBlob
I get the following error while creating one of the fields at the time of deployment.
org.jboss.deployment.DeploymentException: Error while creating table; - nested throwable: (java.sql.SQLException: General error, message from server: "BLOB column 'start_ip' used in key specification without a key length")
I have searched on the net and came up with the following,
it seems that we need to specify the column legnth in the create table statement. I would have to use the following
CREATE INDEX part_of_name ON customer (name(10))
if i was directly working on the database @ command line.
But i am using CMP, so how do i fix this ?
Any help is appreciated

Hi Angel,
1. U code must be absolutely right.
2. The problem is with this general bapi.
3. I also faced the same problem,
   but there is no solution for this
    on SDN.
4. After posting the bapi, (also using commit)
   the message says, Docuement xXX created,
but actually there is no document
   in tables.
5. Even the Number Range is incremented,
   but no document.
6. Its really a mystery for me.

Problem with BLOB image retrieval

We are on Coldfusion 9,0,1,274733. I checked on "Enable binary large object retrieval (BLOB)" on the database but the image is still cut off (3/4 partly grey). On our dev server it works perfectly, our production server just gives off the partly grey images. I checked the CF database settings between dev and production and they are exactly the same. We restarted the server but still the same problem. It is like Coldfusion doesn't see the setting changes. Anyone else has this problem?

We found the solution. Our production servers are in a clustered environment. You have to enable "Enable binary large object retrieval (BLOB)" at the instance cluster level. You will have to do this change on all the instances in the cluster. I was only enabling it at the "local" level on each server in the cluster (which didn't work).
In CF Admin:
Enterprise Manager > Instance Manager > select the instance and enable BLOB

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.

Typical problem with MASTER_IDOC_DISTRIBUTE

I have written the custom program to fetch the data and to form an outbound IDoc using MASTER_IDOC_DISTRIBUTE.
The problem is when i execute the pgm 1st time the IDoc got generated. As it was in Yellow state i tried to execute the program RSEOUT00. Even then it was in yellow state.
Now again i ran the custom program and create danother IDoc. Even now this IDoc is also in Yellow state. But now when i ran RSEOUT00 program with these two IDoc numbers, now the 1st one got into green while the 2nd remained in Yellow.
Now my Questions are
1. First of all why it was in yellow color when i ran the program first time even though when i set "Trigger immediately " at partner profiles.
2. Why the first one is going into green state when the second idoc got generated ?

HI Friends,
i have solved the issue by myself.
I have just used the FM EDI_DOCUMENT_DEQUEUE_LATER before commit wok statement.
Can any one explain me the reason why it worked out ?

Toplink with mysql: problem with blob size

I'm using toplink with a mysql database. I want to store some data in a blob.
In mysql there exist different sizes of blobs (in my case I need a mediumblob).
But if I create the scheme for the database with jpa/toplink it alway creates only a column with type blob.
I can explicitly tell the database to use a mediumblob by this:
@Column("MEDIUMBLOB")
But by doing this I limit my program to mysql of course, as this data type is not known to other databases.
Does anybody know a more elegant solution to setting the blob size?
for example with hibernate it can be done this way:
@Column(length=666666)

Looks like you are using JPA, and in JPA you would set the columnDefinition to the type that you want, e.g.
@Lob
@Column(name="BLOBCOL", columnDefinition="MEDIUMBLOB")
byte[] myByteData;
As you mentioned, this does introduce a dependency on the database. However, you can always either put the Column metadata in XML, or override it with something else later in XML.
The length attribute was intended and specified for use with Strings but I guess there is no reason why it couldn't be used for BLOBs as well (please enter an enhancement request, or submit the code to add the feature to EclipseLink). Be aware, though, that doing so at this stage is going to be introducing a dependency on the provider to support a non-spec defined feature.

"Long fetch" problem with BLOBs

When I try to read BLOB fields from foreign database (Interbase) (in PL/SQL server code), I often got this error. After increasing HS_RPC_FETCH_SIZE and HS_LONG_PIECE_TRANSFER_SIZE it stops happening.
But in Forms when reading into Image item it still appears from time to time.
Any ideas what it depends from or how to solve this problem?

No Ideas? May it perhaps be a restriction of db-admin?
