Generate Software That Used VB As Front End - Oracle 10G As Back End?
Mar 31, 2007
I am trying to generate a software that used VB as the front end and Oracle 10G as the back end. I have noticed that the date format is VB is : m/dd/yyyy whereas the date format in oracle is dd-mm-yyyy. Whenever i try to insert a tuple with either of the date formats, the program halts running and after a long time , i get a message saying a deadlock was encountered. I have never had any formal introduction to either of the two tools

When you create a backup in SQL Server, whether the backup is on disk or on tape, SQL Server writes the letters TAPE to the first four bytes of the backup. Does Oracle write any specify value to the front of every backup, and if so, what are the first four bytes?

I have a shells script which invokes a SQL file. However even with AUTOCOMMIT OFF and on SQLERROR EXIT ROLLBACK. Sqlplus fails to rollback.
My sql file has 3 lines 3 are correct and 1 is incorrect. For example:
INSERT INTO TEST_ROUTING VALUES (24, 'ROUTING');
INSERT INTO TEST_ROUTING VALUES (25, 'ROUTING');
INSERT INTO TEST_ROUTING VALUES (26, 'ROUTING);
Lets say file is called 1.sql
My shell script invokes this SQL as follows: (Where $File1 = 1.sql)
$SQLPLUS_PATH/sqlplus -s /nolog <<-EOF>> ${LOGFILE}
connect $DB_USER/$Password1@$Database1
SET AUTOCOMMIT OFF
@$File1
WHENEVER SQLERROR EXIT ROLLBACK;
EOF
[code]......
So tried SET AUTOCOMMIT, tried SQLERROR ROLLBACK and tried few variations.

I am trying to login through front end application. I am getting the error login failed.
I tried to login from back end using same USERID and password. In the login page it's asking for EDUSERID and password. I tried to connect from backend to the database using same EDUSERID and password and it's working fine. But why from front end application I am unable to login.

I am hoping to test the behavior of a complex web application that is backended by an Oracle 9i database, against an upgrade to 11g database.
The current setup runs basically on 4 Solaris servers, The database, the Oracle Application Server (version 10 something) (2 instances running on the node/server with no OHS), an install of OAS/OHS as a load balancer box, and the non-OHS Apache2 web server front. Apache takes the request from the web and reverse-proxies it to the OHS load balancer, which sends it to one of the two instances on the single application server. This is a java application and uses an Oracle 9i database to feed it.
I have had enough server resources to clone the database, the app server and the web server, and upgrade the database to 11g. I am unable to setup an OHS load balancer box.
So my question is, how do I configure the Apache WS to communicate directly with the OC4J container(s). I can shut down an instance if that simplifies things. Or, if I had to I could look into standing up OHS in the OAS install, as that seems to be where all the info is focused on the technical info sites (Oracle and others), but since these are clones and I think it might be easier to just short circuit around the now missing load balancer box. Many configurations have already been done to be sure the 'clone' identifications are self-referencing, like the hosts file, etc. to point to resources in the Cloned environment.

Where as changes made to the other fmb is working perfectly fine. Is there any deployment issues which needs to be taken care off in oracle 10g.

I am trying to write which will return cursors to front end program.The logic which I got stuck is while exiting the procedure.I am having some cursors in teh procedures which are read by the front end script.I have one condition which when satisfied I have to exit from the procedure.But the constraint I am facing is if I exit at that logic, oracle closes all the cursor and front end script is not able to read teh cursor and hence throws an error.Is there any way to exit the procedure without closing the REF cursors.

that are my biggest tables
Users use front end (called ESS Console) and when they try to open one of those tables they wait very long (really bad performance). Sometimes the GUI even hanging without displaying results.
Does Partitioned Tables feature works for better performance?

The requirement is, the combination of col1,col2,col3 and col4 should always be unique, and wherever the col1, col2,col3 are same then col4 should be the sequence, starting from 1. Likewise the data should be updated back to the table.I'm able to do this using PL/SQL. Can I do the same using a single update statement?
create table tab1 (col1 number(5), col2 number(5), col3 number(5), col4 number(5));
Existing Data:
insert into tab1 values (101,521,3,1);
insert into tab1 values (101,521,3,1);
insert into tab1 values (101,522,3,2);
insert into tab1 values (101,522,3,2);
insert into tab1 values (101,523,3,1);
insert into tab1 values (101,523,3,2);

I come from a world of MSSQL and have been thrown into doing some Oracle work. Great! Ok, moving on.. I work in an environment where I do not have direct access to the database tables that I need data from. As a workaround, I have been asked to create a stored procedure that will be loaded into our CRM system's production db once it goes through the internal "approval" process.Basically, I need to return a result set back to the client by calling a stored procedure.
Version 1 of this that was already in place was done with the following code.
procedure events_by_day (p_start_date IN OPERATION_LOG.DT%type,
p_end_date IN OPERATION_LOG.DT%type,
p_results OUT SYS_REFCURSOR) IS
BEGIN
OPEN p_results FOR
[code]....
Then the code is executed from the client side like so:
events_by_day(p_start_date => to_date('2012-3-27 00:00:00', 'YYYY-MM-DD HH24:MI:SS'),
p_end_date => to_date('2012-3-29 23:59:59', 'YYYY-MM-DD HH24:MI:SS'),
p_results => r_cursor);
LOOP
FETCH r_cursor
INTO event_date, event_acct_no, event_type, event_count;
[code]....
As you can see, a SYS_REFCURSOR was used in this case to pass the data back.

I have a 3 node RAC server on Windows Server 2008. Last week the hard drive went out on one of the nodes and I have had to rebuild as I could not recover anything.
I went through and deleted the old node and now I have just finished adding the new node back to my cluster via documentation. Once I created the new instance on that server DBCA attempted to start and it failed gaving me a crs error. I found out later that the other 2 nodes went down and the new one that did not start correctly was the only one up!! I went and stopped the new instance and restarted the first 2. The associated services did not start with the instance so I had to start each manually. The trace files show an ORA-29702 error with cluster group service and the instance being stopped on both of the existing nodes. No other error messages stood out.
Now I cannot get any crs services to start on that 3rd node even if I attempt to start manually. I have also tried stopping all and restarting and that does not work. I found another post on this forum from you and followed it. The ASM service was fine the entire time through all the logs and I don't know how to verify LMON in Windows but I didn't see any LMON errors in the alert log. Also, the voting disks are online. Each node has their own and they are mirrored. Where else to look?

We have a forms application in Forms 10g. We scan a document and gets it to a image item in the Form. Now, we need to pass this image to a 3rd party application (document mgt. system, ). They have given us a web-service for this. We have to convert the image to a BASE64 string and then invoke the web-service method and input it.
The, 3rd party application document management system will also send images as BASE64 strings through the web-service. We need to convert them back to a blob and put to an image item in the form so that it can be viewed by the end-user.
So, how can we convert a image item in form (as BLOB) to a base64 string and also do the reverse???
