Dbms_xslprocessor problems in PL/SQL

Hi all :)
-- This is a cross-posting of a question I placed on the XMLDB forum, but there seems to be more activity here
-- Sorry about the duplicate
I was wondering if anyone has any ideas about this problem I'm having:
When using the dbms_xslprocessor in PL/SQL, I consistently get dropped connections when trying to either transform a document, or search a document via XPath. So, for instance, if I call dbms_xslprocessor.selectSingleNode('XPATH'), the connection will drop out with the following error (I'm calling a stored procedure here):
ERROR at line 1:
ORA-03113: end-of-file on communication channel
Similar problems happen on XMLType.transform(stylesheet).
I've only managed to have this happen when transforming or searching documents that are not in the default (i.e., xmlns="") namespace, but I can't get rid of the namespace (too much other code is relying on it being there).
What's even stranger is that the XSLPROCESSOR package works, but DBMS_XSLPROCESSOR package does not. Unfortunately, the XSLPROCESSOR package doesn't seem to handle namespaces well, and inserts seemingly random namespace declarations in the transformation results (for instance, on the root element, it puts in "xmlns:xmlns='http://www.w3.org/2000/xmlns/'") or redeclares namespaces on nodes that already have that namespace defined for them by their parents. Namespace prefixes, too.
I should mention that I'm absolutely sure the stylesheet is correct. External processors like MSXML and Xalan produce correct results.
Does anybody have any ideas as to what this might be?
Thanks in advance,
Constantine

what version of the XDK are you using ?
Version of the javaparser ?

Problems with PL/SQL packages

Hello,
I face the following problem with PL/SQL stored procedures. The Oracle
version is 8.0.5 on Windows NT 4. The PL/SQL package has a set of procedures and functions.
The main procedure of the PL/SQL package is triggered from VC++ executable. If for some reason,
an exception is caught in the stored procedure (like no_data_found
exception), then the following problem occurs.
If we try to trigger the stored procedure again through the VC++ executable,
the variables in the stored procedures have the values as in the previous
execution. They are not getting initialised. (The same database connection
is used in VC++ executable).
Currently, only if a new connection to the database is used , the problem is
solved.
Also, change in the input parameters of the procedure is not reflected, once the procedure fails because of any exception. Only the input which was given during the time of execution when the procedure failed,is considered.
What could be the reason for this problem and how can this be corrected?
Please send in your suggestions.
Thanks and Regards,
Ramya Priya

Hi Keith,
I am connecting to the database as the package owner..
I have noticed earlier that I have problems when capturing triggers also.. The content of one large trigger contains 36371 characters and when capturing it from DB, the content was truncated to 28020 characters in Designer.
Our ideas with capturing the DB packages/procedures were to use the Designer as version control system.
We wanted to have all objects used in a project in Designer.. entities, tables, triggers, packages, procedures, Forms files, etc. in order to make a configuration for a project release.
Thank you,
Claudia

How to avoid performance problems in PL/SQL?

How to avoid performance problems in PL/SQL?
As per my knowledge, below some points to avoid performance proble in PL/SQL.
Is there other point to avoid performance problems?
1. Use FORALL instead of FOR, and use BULK COLLECT to avoid looping many times.
2. EXECUTE IMMEDIATE is faster than DBMS_SQL
3. Use NOCOPY for OUT and IN OUT if the original value need not be retained. Overhead of keeping a copy of OUT is avoided.

Susil Kumar Nagarajan wrote:
1. Group no of functions or procedures into a PACKAGEPutting related functions and procedures into packages is useful from a code organization standpoint. It has nothing whatsoever to do with performance.
2. Good to use collections in place of cursors that do DML operations on large set of recordsBut using SQL is more efficient than using PL/SQL with bulk collects.
4. Optimize SQL statements if they need to
-> Avoid using IN, NOT IN conditions or those cause full table scans in queriesThat is not true.
-> See to queries they use Indexes properly , sometimes Leading index column is missed out that cause performance overheadAssuming "properly" implies that it is entirely possible that a table scan is more efficient than using an index.
5. use Oracle HINTS if query can't be further tuned and hints can considerably help youHints should be used only as a last resort. It is almost certainly the case that if you can use a hint that forces a particular plan to improve performance that there is some problem in the underlying statistics that should be fixed in order to resolve issues with many queries rather than just the one you're looking at.

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,

Well, turns out that this cryptic error is due to an older

I should also mention that I'm ABSOLUTELY sure that the stylesheets I'm using for transformation are correct as of XSLT ver. 1.0 -- multiple external processors (Xalan and MSXML, specifically) give the correct result on the same stylesheet.

Problem with extended SQL functions in RTF Template

Hello,
I'm new to BI Publisher and I'm trying to create a new rtf template. I've created my layout and added fields without any problems, but I'm having trouble trying to insert calculations such as add,substract,multiply,divide, etc.
Here is an example of what I'm trying to do:
<?xdofx:STAFF_ASMT+100?>
Where STAFF_ASMT is one of my fields. When I add this function all I get is the actual value from that field returned on the first page, and then on other pages I get the value plus an extra zero.
So with my example data below I get: 6600 on page 1 and 51830 on page 2. Any ideas on what I'm doing wrong or if it is possible to do what I'm doing? Also, is it possible to add/substract/multiple two or more fields together?
Something like this: <?xdofx:STAFF_ASMT+GROSS_INV?>
I was going to add all of these functions to my SQL statement, but I have 30 or so calculations I want to perform in the layout and I don't want to have to write that all out in SQL.
<ROWSET>
<ROW>
<STAFF_ASMT>6600</STAFF_ASMT>
<GROSS_INV>0</GROSS_INV>
</ROW>
<ROW>
<STAFF_ASMT>5183</STAFF_ASMT>
<GROSS_INV>0</GROSS_INV>
</ROW>
</ROWSET>
Thanks for your help

Problem with java.sql.Clob and oracle.sql.CLOB

Hi,
I am using oracle9i and SAP web application server. I am getClob method and storing that in java.sql.Clob and using the getClass().getName() I am getting the class name as oracle.sql.CLOB. But when I am trying to cast this to oracle.sql.CLOB i am getting ClassCastException. The code is given below
java.sql.Clob lOracleClob = lResultSet.getClob(lColIndex + 1);
lPrintWriter = new PrintWriter(new BufferedWriter (((oracle.sql.CLOB) lOracleClob).getCharacterOutputStream()));
lResourceStatus = true;
can anybody please tell me the what is the problem with this and solution.
thanks,
Ashok.

Hi Ashok
You can get a "ClassCastException" when the JVM doesn't have access to the specific class (in your case, "oracle.sql.CLOB").
Just check your classpath and see if you are referring to the correct jar files.

Problem with the SQL Data Source (Essbase server in Unix Env)

I too have the same problem.
I have setup the Datasource for an Oracle db in the Essbase Server (which is on a Unix Box) using the Oracle Wire Protocol.I tested the ODBC connection in the Server and it connect with the credentials.
But if i choose the same DSN in the EAS and try to connect i get the below error
Error: 1021001 Failed to Establish Connection With SQL Database Server.
I even downloaded a document from the Oracle site.. on the SQL interface in Essbase but i could not find the inst-sql.sh file to enable Essbase SQL Interface on the server. Is this required??
I tried with both the User & System DSN on the server but no luck.
Any help on this will be highly appreciated. Thanks in advance.
Posting in a new thread since the old one is answered and no points available to score.

It can depend on the version, it is different for version 11, further information :- How to define a relational data source in (odbc.ini) V11 Essbase?

Getting problem while installing Sql Server 2012

I am using Windows 8 in my system. I am trying to install Sql Server 2012 in my system .
But i am getting following error in the final.
The required MSI package 'D:\SQL Server 2012\x86\setup\sql_engine_core_shared_msi' doesn't exist.
Please, help me quickly.

Hi，
You post same question 3 times. Please avoid this practice on Forum, I
have merged the same thread into this thread . Thanks for your understanding.
In addition, as other post, you can copy the missing .msi file from the complete and unbroken installation media to your MSI package path. Then run as administrator again. And also check if your account has read and write permission for your installation
media saving path. If the error still exists, you can check the SQL setup logs (Detail.txt and summary.txt) for analysis.
There is similar issue about installing SQL Server failed due to miss the required MSI package.

Problem writing a sql query for a select list based on a static LOV

Hi,
I have the following table...
VALIDATIONS
ID          Number     (PK)
APP_ID          Number
REQUESTED     Date
APPROVED     Date
VALID_TIL     Date
DEPT_ID          Number     (FK)
I have a search form with the following field item variables...
P11_DEPT_ID (select list based on dynamic LOV from depts table)
P11_VALID (select list based on static Yes/No LOV)
A report on the columns of the Validations table is shown based on the values in the search form. So far, my sql query for the report is...
SELECT v.APP_ID,
v.REQUESTED,
v.APPROVED,
v.VALID_TIL,
d.DEPT
FROM DEPTS d, VALIDATIONS v
WHERE d.DEPT_ID = v.DEPT_ID(+)
AND (d.DEPT_ID = :P11_DEPT_ID OR :P11_DEPT_ID = -1)
This query works so far. My problem is that I don't know how to do a search based on the P11_VALID item - if 'yes' is selected, then the VALID_TIL date is still valid. If 'no' is selected then the VALID_TIL date has passed.
Can anyone help me to extend my query to include this situation?
Thanks.

Hello !
Let's have a look at my example:create table test
id        number
,valid_til date
insert into test values( 1, sysdate-3 );
insert into test values( 2, sysdate-2 );
insert into test values( 3, sysdate-1 );
insert into test values( 4, sysdate );
insert into test values( 5, sysdate+1 );
insert into test values( 6, sysdate+2 );
commit;
select * from test;
def til=yes
select *
from test
where decode(sign(trunc(valid_til)-trunc(sysdate)),1,1,0,1,-1)
       =decode('&til','yes',1,-1);
def til=no
select *
from test
where decode(sign(trunc(valid_til)-trunc(sysdate)),1,1,0,1,-1)
       =decode('&til','yes',1,-1);
drop table test; It's working fine, I've tested it.
The above changes to my first idea I did because of time portion of the DATE datatype in Oracle and therefore the wrong result for today.
For understandings:
1.) TRUNC removes the time part of DATE
2.) The difference of to date-values is the number of days between.
3.) SIGN is the mathematical function and gives -1,0 or +1 according to an negative, zero or positiv argument.
4.) DECODE is like an IF.
Inspect your LOV for the returning values. According to my example they shoul be 'yes' and 'no'. If your values are different, you may have to modify the DECODE.
Good luck,
Heinz

Problem Writing java.sql.Date to MS Access

I have a relatively simple application that is for my own use (not distributed on an enterprise-wide basis). As I don't have an IT staff, I'm using a rudimentary Java front-end (v1.3.1) and a Microsoft Access backend.
I seem to have trouble using INSERT/UPDATE statements with the MS Access Date/Time data type. Below is an example of code being used (id is defined as Text, amount is a Number and timestamp is Date/Time):
conn = DriverManager.getConnection("jdbc:odbc:markets", "", "");
conn.setAutoCommit(true);
String sql = "INSERT INTO temp (id, amount, timestamp) VALUES (?, ?, ?)";
PreparedStatement stmt = conn.prepareStatement(sql);
String id = args[0];
int len = id.length();
java.sql.Date dt = new java.sql.Date(new java.util.Date().getTime());
stmt.setString(1, id);
stmt.setDouble(2, id.length());
// I think the problem is here - the JDBC driver doesn't properly map dates to Access???
stmt.setDate(3, dt);
stmt.execute();
stmt.close();
conn.close();And I get the following error:
java.sql.SQLException: [Microsoft][ODBC Microsoft Access
Driver] Syntax error in INSERT INTO statement.
        at sun.jdbc.odbc.JdbcOdbc.createSQLException (JdbcOdbc.java:6879)
        at sun.jdbc.odbc.JdbcOdbc.standardError (JdbcOdbc.java:7036)

        at sun.jdbc.odbc.JdbcOdbcStatement.execute (JdbcOdbcStatement.java:338)
        at TestWritingDate.main(TestWritingDate.java:31) I'm virtually certain this is a translation problem with
the java.sql.Date and the JDBC driver. But I can't seem
to overcome this. Any help is DESPERATELY needed.
Thanks.

That was it....thanks...didn't even consider that....perhaps I should start using class names that are already in use too :-). Thanks again...

I have successfully configured ODBC and freeTDS so that I can connect using isql and query my MSSQL database. The problem I am having is connecting Oracle to MSSQL, I am sure it is a simple configuration error but I have been going round in circles with this and hope someone can help!

(Because I have put the actual path to the driver in the odbc.ini file I don;t believe the odbcinst.ini file is actually used)

right - I can tnsping my hscerm instance and that returns ok so I'm fairly sure the configuration is fine for both tnsnames.ora and listener.ora. I can isql connect to the ODBC defined name for the the MSSQL database. but when I create a database link in Oracle and then test it I get the following trace output :-

Now I can clearly see the error "Data source name not found, and no default driver specified" which according to all the documentation means that the entry HS_FDS_CONNECT_INFO=CERM does not match the entry in my odbc.ini file ([CERM]) but for the life of me I can;t see why they don;t match ??
Any help greatly received.

Yeah I verified with isql but I have changed the odbc.ini file as you suggested -

I can also ping both the hostname and ip address of the MSSQL server.
