JVM hangs while executing a sql query
My JVM hangs while I try to execute an update query. I am using JDBC thin client and Oracle 9i as database. Can someone please suggest what could be wrong.
I have a serious problem regarding the usage of Prepared Statement.
I am working on J2EE based application with the application server as Oracle 9ias.We have mostly used Prepared in 0ur queries.But one our application got implemented we are facing some strange problems.The first instance was a web page was getting hanged and does not give any results.But this had worked fine in all our testing environment.We analysed the table which it uses and still no result.Finally we changed prepared statement to statement and the result page came within seconds.
The second instance is the main issue.Again a query is getting hanged when we try to process it through the web page.We again tested it by converting from prepared statement to statement and its coming within seconds.
Can someone give me some input.Is there any databse parameter that is controlling this prepared statement or statement.

ORA-03113 : end-of-file on communication channel while running a SQL Query
Hi,
While executing the following query, we are facing ORA-03113 : EOF on communication channel error.
SELECT
FROM QDF_CLSS_SHENG_HIST
/*WHERE* a.FACT_TYPE_CODE='BS'
AND */
WHERE (SRCE_SYS_ID = 850 OR (SRCE_SYS_ID IN (1747,1764) AND GEO_ID IN (826,372) AND PRTTN_BY_FUNC_DATE>=to_date('20060701','YYYYMMDD') ))
When we remove one of the values in the SRCE_SYS_ID's 'IN' condition the error is not thrown, e.g.
WHERE (SRCE_SYS_ID = 850 OR (SRCE_SYS_ID IN (1747) AND GEO_ID IN (826,372) AND PRTTN_BY_FUNC_DATE>=to_date('20060701','YYYYMMDD') ))
The version of the Database we are using is 10.2.0.3.0 - 64bi. Is this a common error in this version of the database because when we ran the same query in a 9i database we got no such error.
P.S : QDF_CLSS_SHENG_HIST table is partitioned on SRCE_SYS_ID and PRTTN_BY_FUNC_DATE
Thanks,
PuneethYes, we get the same error and no dumps are getting created.It might be interesting to look at a trace file for this SQL statement with event 10046 at level 12 and event 10053 at level 1 enabled for the session. You may need to modify the query slightly to make certain that a hard parse is required (possibly by specifying a couple of the column names to be returned rather than *). Take a look through the raw trace file for something like this
cost: -1.#IND card: 1.#INFThere is at least one query in the ERP package that I use that will output the following in a 10053 trace when optimizer_features_enable is greater than 10.1.0.4, followed by an ORA-600:

How to execute a sql query in VO????
Hi every body.
Can you show me the way to execute a sql query in VO.
For example: I have a viewobject1, and I add a new method void execSQL() before the last '}' of the java file of viewobject1 like this:
public void execSQL() {
String strSql = "Select sysdate from dual";
I want to execute strSql query and return a Resultset, how can I perform ???
Thanks a lot.The executeQuery method in ViewObjectImpl does not return a ResultSet.
ViewObjectImpl voImpl;
voImpl.setQuery(strSql);
voImpl.executeQuery(); -
Error while executing the workbook query.
Hi guyz
i'm getting an error while executing the workbook Query. The actual problem is there is a filter for REQUID in the query definition for removing the doble count. there is customer exit written. the report works fine in DEVELOPMENT but it is not working in quality.
The query on which this workbook is created is working fine, but the problem is when we execute the workbook i'm facing this issue.
we re-transported the queries but still we are facing the same problem.
while we execute the query we are prompted for variable entry(Optional) for date. when we press OK we get the below error
" NO SID value found for the value REQU_4DQT75Y2RJPVT4PXZ4LHC70V3 of characteristic"
the request is not available in the BW system. the request was deleted long back, but it is still referring to the same the request id
could someone please tell me where we went wrong and why we are getting this error.
Regards,
Anil VaddeHey ,I think data load to your target on which the query was based had some issue.
Can you check the data load to the data target.change the status of request concerned to red and delete.do reconstruct if neeed..I think the request had some issue.
Even you can go to RSRQ or RSMO and filter on the basis of this request and see its status.
Regards,

Error while executing report in query designer
Dear Folks,
I am geting following error while executing report in query designer.
Error:500 E
an exception raised because of 0analysis pattern.
Hence,i am unable to execute any report.
Need help.
ThanksHi Kitu G,
I think this is something to do with the bex web 0ANALYSIS* objects not being installed in your BW system.
I would try and do the following:
- Goto RSA1 > BI Content > BEx Web Template (BTMP)
- Then double-click on Select Object.
- Highlight all objects that start with 0ANALYSIS_PATTERN
- Click on Transfer Selections, and then Install.
If you can't do the above in prd, do it in DEV, then transport the objects to prd.
After all this, try re-running your queries.
Any questions/clarification just let me know
Cheers.

How to execute an SQL query present in a string inside an ABAP program?
hello,
How to execute an SQL query present in a string inside an ABAP programRaut,
You can execute Native SQl statements.
Ex: To use a Native SQL statement, you must precede it with the EXEC SQL statement, and follow it with the ENDEXEC statement as follows:
EXEC SQL [PERFORMING <form>].
<Native SQL statement>
ENDEXEC.
There is no period after Native SQL statements. Furthermore, using inverted commas (") or an asterisk (*) at the beginning of a line in a native SQL statement does not introduce a comment as it would in normal ABAP syntax. You need to know whether table and field names are case-sensitive in your chosen database.
In Native SQL statements, the data is transported between the database table and the ABAP program using host variables. These are declared in the ABAP program, and preceded in the Native SQL statement by a colon (:). You can use elementary structures as host variables. Exceptionally, structures in an INTO clause are treated as though all of their fields were listed individually.
If the selection in a Native SQL SELECT statement is a table, you can pass it to ABAP line by line using the PERFORMING addition. The program calls a subroutine <form> for each line read. You can process the data further within the subroutine.
As in Open SQL, after the ENDEXEC statement, SY-DBCNT contains the number of lines processed. In nearly all cases, SY-SUBRC contains the value 0 after the ENDEXEC statement. Cursor operations form an exception: After FETCH, SY-SUBRC is 4 if no more records could be read. This also applies when you read a result set using EXEC SQL PERFORMING.
EXEC SQL PERFORMING loop_output.
SELECT connid, cityfrom, cityto
INTO :wa
FROM spfli
WHERE carrid = :c1
ENDEXEC.
Pls. Mark If useful -

For example;
If I write a name; I want to add that name to my table in my database.
Could you give an example please?
Thank youPreparedStatement ps = con.prepareStatement("insert into foo (name, birthdate) values (?, ?)"); // double check my sql insert syntax. I'm not sure if it's right.
String theName = ...; // get name from what user enters

OCI crash while executing PL/SQL
HI,
I have a multithreaded application which uses OCI. The application has a master thread and spwans 4 child threads that connect to the db and execute specific queries. The problem occurs while trying to execute the last PL/SQL command which includes some bfile operations. I had read that OCI does not mutex properly on LOB operations, but I do not get any error, the application just hangs. Attached is part of the code that has all OCI calls.
The culprit is the update_tables function. The application hangs in there when processing is very close in time for threads.

How to execute a SQL Query in Ms-Access
Hi,
I've a query which fetches the data from the tables based on daily transactions.
I mean, the data gets updated daily basis.
Now, i want to send the user a Ms-access work sheet with the query written, so that when ever the query is executed, it would fetch the records (with latest updates).
I found some documents in google to, how to write sql query in ms-access.
How ever, i'm unable to find the connection setup.
how do i connect to oracle database using ms-access??
Can any one please help me regarding this.
Thanks,
SanthoshYou can try this tutorials
http://www.reo.gov/gis/tools/infobase/LinkAccessToOracle.pdf
Basically steps include,
Install and configure Oracle client
Configure ODBC DSN using correct TNS name configured in first step
Link the table from Msaccess, make sure you linked the table not import it. -

Parameter index move while executing PL/SQL stored procedure/function
Hello, community.
Have a question for you. It looked like very easy to write some small JDBC-wrapper to handle stored procedure/functions call for Oracle.
Here is the code snippet of it:
import java.io.Serializable;
import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.SQLException;
import java.util.HashMap;
import java.util.Iterator;
import javax.sql.DataSource;
import oracle.jdbc.driver.OracleTypes;
import org.apache.log4j.Logger;
public class SmallHelper {
public static final int CALL_TYPE__PROCEDURE = 1;
public static final int CALL_TYPE__FUNCTION = 2;
public static final int PARAMETER__IN = 1;
public static final int PARAMETER__OUT = 2;
private static final Logger log = Logger.getLogger(SmallHelper.class);
private Connection con = null;
private CallableStatement statement = null;
private String name;
private int type;
private int resultType;
private HashMap arguments = new HashMap();
* Creates connection using data source as parameter.
* @param ds - data source
* @throws EhlApplicationException
public SmallHelper(DataSource ds) throws Exception {
try {
con = ds.getConnection();
catch (SQLException e) {
ExceptionHelper.process(e);
public void registerProcedure(String name) {
this.name = name;
this.type = CALL_TYPE__PROCEDURE;
public void registerFunction(String name, int resultType) {
this.name = name;
this.resultType = resultType;
this.type = CALL_TYPE__FUNCTION;
* NB! When You're dealing with stored function index should start with number 2!
public void registerArgument(int index, Object value, int type, int inOutType) {
arguments.put(new Long(index), new CallableStatementArgument(value, type, inOutType));
private String getSQL() {
StringBuffer str = new StringBuffer("{ call ");
if ( type == CALL_TYPE__FUNCTION )
str.append(" ? := ");
str.append(name).append("( ");
for ( Iterator i = arguments.values().iterator(); i.hasNext(); ) {
i.next();
str.append("?");
if ( i.hasNext() )
str.append(", ");
str.append(") }");
return str.toString();
public void execute() throws SQLException{
String query = getSQL();
statement = con.prepareCall(query);
if ( type == CALL_TYPE__FUNCTION )
statement.registerOutParameter(1, resultType);
for ( Iterator i = arguments.keySet().iterator(); i.hasNext(); ) {
Long index = (Long) i.next();
CallableStatementArgument argument = (CallableStatementArgument) arguments.get(index);
int type = argument.getType();
if ( argument.getInOutType() == PARAMETER__OUT )
statement.registerOutParameter(index.intValue(), type);
else if ( type != OracleTypes.CURSOR )
statement.setObject(index.intValue(), argument.getValue(), type);
log.info("Executing SQL: "+query);
statement.execute();
public CallableStatement getStatement() {
return statement;
public void close() throws EhlApplicationException {
try {
if (statement != null)
statement.close();
if (con != null)
con.close();
catch (SQLException e) {
EhlSqlExceptionHelper.process(e);
private class CallableStatementArgument implements Serializable{
private Object value;
private int type;
private int inOutType;
public CallableStatementArgument(Object value, int type, int inOutType) {
this.value = value;
this.type = type;
this.inOutType = inOutType;
public int getType() {
return type;
public Object getValue() {
return value;
public int getInOutType() {
return inOutType;
}It was really done in 10-15 mins, so don't be very angry at code quality :)
Here is the problem.:
helper.registerProcedure("pkg_diagnosis.search_diagnosis");
helper.registerArgument(1, null, OracleTypes.CURSOR, EhlJdbcCallableStatementHelper.PARAMETER__OUT);
helper.registerArgument(2, pattern, OracleTypes.VARCHAR, EhlJdbcCallableStatementHelper.PARAMETER__IN);
helper.registerArgument(3, lang, OracleTypes.VARCHAR, EhlJdbcCallableStatementHelper.PARAMETER__IN);
helper.registerArgument(4, EhlSqlUtil.convertSetToString(langs, ","), OracleTypes.VARCHAR, EhlJdbcCallableStatementHelper.PARAMETER__IN);
helper.registerArgument(5, EhlSqlUtil.convertSetToString(diagnosisClass, ","), OracleTypes.VARCHAR, EhlJdbcCallableStatementHelper.PARAMETER__IN);
helper.registerArgument(6, parentId, OracleTypes.NUMBER, EhlJdbcCallableStatementHelper.PARAMETER__IN);
helper.execute();
ResultSet rs = ((OracleCallableStatement) helper.getStatement()).getCursor(1);
procedure definition:
procedure search_diagnosis (l_res OUT dyna_cur,
in_search_string IN VARCHAR2,
in_search_lang IN VARCHAR2,
in_lang_list IN VARCHAR2,
in_diag_class_list IN VARCHAR2,
in_parent_id IN NUMBER) Procedure call has inner check that fail because of som strange reason:
in_search_string has 2 as index, that is correct. but procedure recieves is as number 3 in parameter list (what is in_search_lang). Other parameters are moved to. It seems like a cursor takes 2 places in definition. It's clear that if I put in_search_string as 1 parameter and cursor as 0 I'll get invalid parametr bindong(s) exception. So... any ideas why 2nd parameter is actually 3rd?
Thanks beforehand.hmm...moreover:
if we change procedure to function and call it in a simple way:
CallableStatement stmnt = helper.getConnection().prepareCall("begin ? := pkg_diagnosis.search_diagnosis(?,?,?,?,?); end;");
stmnt.registerOutParameter(1, OracleTypes.CURSOR);
stmnt.setString(2, pattern);
stmnt.setString(3, lang);
stmnt.setString(4, langs);
stmnt.setString(5, diagnosisClass);
stmnt.setObject(6, parentId, OracleTypes.NUMBER);
stmnt.execute();
ResultSet rs = (ResultSet) stmnt.getObject(1);the exception is:
[BEA][Oracle JDBC Driver][Oracle]ORA-06550: line 1, column 14:
PLS-00382: expression is of wrong type
ORA-06550: line 1, column 7:
PL/SQL: Statement ignoredif we return some string or number - it works. but when we want cursor back - it fails.
cursor is defined like ordinary dynamic cursor:
