Deadlock in Oracle.sql.ARRAY type

Hi,
We've come across the deadlock situation below when running multiple J2EE MDB instances that are trying to write to the DB:
[deadlocked thread] [ACTIVE] ExecuteThread: '7' for queue: 'weblogic.kernel.Default (self-tuning)':

Looking at the ARRAY.toBytes() method:
public byte[] toBytes()
throws SQLException
synchronized (getInternalConnection())
return this.descriptor.toBytes(this, this.enableBuffering);
..., it synchronizes on the following method (getInternalConnection() -> getPhysicalConnection()):
oracle.jdbc.internal.OracleConnection getPhysicalConnection()
if (this.physicalConnection == null)
try
this.physicalConnection = ((oracle.jdbc.internal.OracleConnection)new OracleDriver().defaultConnection());
catch (SQLException localSQLException)
return this.physicalConnection;
defaultConnection() does the following:
public Connection defaultConnection()
throws SQLException
if ((defaultConn == null) || (defaultConn.isClosed()))
synchronized (OracleDriver.class)
if ((defaultConn == null) || (defaultConn.isClosed()))
defaultConn = connect("jdbc:oracle:kprb:", new Properties());
return defaultConn;
So there's synchronizations on the connection instance and OracleDriver.class object... I can't see how this can deadlock. To get to the point of needing the lock on OracleDriver.class, the thread would already have the lock on the connection instance.... clearly I'm missing something.
Thanks

Welcome to the forum. If you want help, at least try to think where to post a question and look for a forum that matches the topic. Lets examine what you have:
- its Weblogic, so if you would ask a non-programming related question anywhere it would be in the Weblogic forum
- HOWEVER, if you check the top of the stacktrace, you'll see that the problem stems from the JDBC driver, so a JDBC related forum would be a closer match
For future reference, Weblogic specific questions should go here: https://forums.oracle.com/forums/category.jspa?categoryID=193
and JDBC/OJDBC driver related questions should go here: Java Database Connectivity (JDBC)
Final tip: use \ tags to post code so it is readable.

Problem Encountering in oracle.sql.ARRAY type

Hi,
i am using one stored procedure to get a set of records.
i am getting it by mapping those things with java.sql.Array. And after that i am getting the values as ResultSet from that Array. The same thing is working fine in Windows platform. If i posted those thing into Unix - AIX, i am facing an ArrayIndexOutofBoundsException while getting ResultSet from oracle.sql.ARRAY class. I checked out ARRAY instance.it is not null. Both Application and Database are same except O.S.
Can Anybody help me. I need it imm.
Thanks in Advance
Regards
Eswaramoorthy.G

Hi
Did you ever figure out what the problem was with this? We have a client that is experiencing the same problem on AIX but we cannot reproduce using their database running under NT nor Sun. Any information would be appreciated. You can respond directly to [email protected]

Java.sql.SQLException: Internal Error while using oracle.sql.ARRAY.getArray

Hello All,
Here is the issue description. Our application uses Oracle Object Types and LIST. We deployed our application on QA environment which has Oracle 10g. Application runs fine...no issues. Now we moved to UAT. UAT environment is same as QA environment and DBA have created replica of QA database.
Now WAR file which works fine with QA database , somehow doesnt work with UAT database. Application throws following exception when code tries to call getArray() on java.sql.Array.
We tried to point UAT weblogic to QA database and it worked fine.....but when we point UAT weblogic to UAT database , we get following exception. So we know that this is a database issue.
DBA claims that QA env database and UAT env database are same.
Can anybody please tell me what wrong here? What setting is not done on UAT database which is done on QA?

This can happen if you use the oracle.sql.ARRAY class with WebLogic.
WebLogic wraps oracle.sql.ARRAY with its own class (i.e. weblogic.jdbc.wrapper.Array_oracle_sql_ARRAY). The easiest solution is to replace oracle.sql.ARRAY with the JDBC standard java.sql.Array.
<PRE class=jive-pre><CODE class="jive-code jive-java">Object[] items = (Object[])array.getArray();
if (items.length > 0) {
for (int i = 0; i < items.length; i++) {
Object arrayItem = items;
}
}
</CODE></PRE>
The array object is a java.sql.Array. Here no unwrapping of the WebLogic wrapper is needed.
If you absolutely need the oracle.sql.ARRAY class than you must use an unwrap API on the WebLogic wrapper class.
<PRE class=jive-pre><CODE class="jive-code jive-java">if (object instanceof weblogic.jdbc.wrapper.Array)
array = (ARRAY) ( ((weblogic.jdbc.wrapper.Array)object).unwrap(Class.forName("oracle.sql.ARRAY")) );
else
array = (ARRAY) object;
</CODE></PRE>
Here, array is an oracle.sql.ARRAY. Try to see if this <A class=bodylinkwhite href="http://www.software-to-convert.com/3gp-conversion-software/3gp-to-myspace-video-software.html">helps</A>. Good luck.
Thanks for your explanation! It's very valuable, It is exactly what I need, I understand this part.

If i use cs.registerOutParameter(4, Types.ARRAY, "SCHEMA_OWNER_NAME.ISSUESECTION_LIST"); Then i wont be getting the error.
COULD ANYONE LET ME KNOW THE WORK AROUND OTHER THAN THE ABOVE SOLUTION LIKE ADDING THE OWNER SCHEMA NAME WITH THE USER DEFINED COLLECTION TYPE.

There couold be two reasons:
1) it depends how u have defined type. if ISSUESECTION_LIST is defined in type SCHEMA_OWNER, then you have to call this ways only 'SCHEMA_OWNER_NAME.ISSUESECTION_LIST'
2) You might have defined using schema_owner_name like scott.<TYPE_NAME>. if its so, then drop it and again define type without using schema owner.
For detail help post your type declaration.

Java.sql.SQLException: Internal Error with oracle.sql.ARRAY getArray()

hi,
I am having having problems with the getArray() of oracle.sql.ARRAY.
Here are the details:
Oracle Database - 9.2.0.6. The JDBC driver used -10.2.0.1 jar.(the latest available).
I am calling a stored procedure from java, that has out param as a collection (VARRAY) of a user defined type.
The stored procedure works fine, if the user/schema used to connect,contains actual type, and i am able to extract the user defined object from the oracle.sql.ARRAY, via getArray().
But if i use a different user to connect which has public synonyms and execute rights to the actual type, i get the following error:

The problem is happening because we have 2 different users to connect to the database. one is the dba user, which contains all the types, packages and other one the application user, which we are supposed to use, to connect via java. This application user does have access to types via public synonym, but it gives the above mentioned error.
Please help :(.
Regards,
Gaurav.

Hi avi,
Even I am getting the same error inspite of preceding the type name with the same user who has created the type.
It has displayed the array length.When I am trying to fetch each array, I am getting the error.
ARRAY simpleArray = (ARRAY) cs.getObject(3);
System.out.println("Array is of length " + simpleArray.length());          ********************** The above stmt prints 2 records ******************
But it goes to exception in the foll stmt..
Object [] objArrStructArray = null;
try{
     objArrStructArray = (Object[]) simpleArray.getArray();
}catch(SQLException e){
     e.printStackTrace();
Do u know abt this?
The foll is the error which I am getting.

NullPointer from constructor of oracle.sql.ARRAY

This is a strange one, I'm hoping someone has seen this before.
I'm seeing a nullpointer exception from the contructor of ARRAY(ArrayDescriptor, Connection, Object)
This occurs when I'm trying to make a call from an application module to a stored procedure with custom database types.
This seems to work fine in the embedded OC4J instance but fails when deployed to an application server on linux. The version is 10.1.2.
thanks for your help.

Avi, thanks for your response. The connection is obtained from a BC4J appmod, which ultimately comes from a pooled datasource.
When I look at the implementation class in the embeded OC4J environment it is com.evermind.sql.OracleConnectionBCELProxy__com_evermind_sql_OrionCMTConnection__SQLBCELProxy. The call to ARRAY works in this environment.
On the application server the runtime implementation of the connection is com.evermind.sql.ConnectionBCELProxy__com_evermind_sql_OrionCMTConnectionFinalize__SQLBCELProxy. This fails with the exception in the original post.
In both environments I can successfuly cast to an OracleConnection so I'm pretty sure both implementaion classes are subclasses of OracleConnection.
Both environments are 10.1.2.
thanks for your help so far.

Oracle.sql.ARRAY incompatible with weblogic.jdbc.vendor.oracle.OracleArray

Hi,
I am facing following issue in my one environment. but in other environment same class path is working fine. I have compared all jar and classpath for both weblogic server.
I am using weblogic 11g.

Creating my Oracle connection works fine ... code as follows:
Context ctxt = getInitialContext();
DataSource dataSource = (DataSource) ctxt.lookup(poolName);
Connection conn = dataSource.getConnection();
OracleConnection oracleConn = (OracleConnection)((WLConnection)conn).getVendorConnection();
I also have reviewed documentation:
http://e-docs.bea.com/wls/docs81/jdbc/thirdparty.html. In section 'Using OracleStruct Extension Methods' it highlights that
java.sql.Struct struct =(weblogic.jdbc.vendor.oracle.OracleStruct)(rs.getObject(2));
None of the documentation actually mentions oracle.sql.STRUCT. For Weblogic to truely provide support for Oracle it needs an easy way of converting to this data type. At present I cannot interact with Oracle APIs until I can create an oracle.sql.STRUCT.

Conversion of java Array to oracle SQL Array while calling Stored Procedure

How java Array can be converted to oracle SQL array while calling Stored procedure with callable statement.
i.e java Array ---> Sql Array in Oracle while setting the datatypes to callable statement arguments.

How to create oracle.sql.array

I need to create an oracle.sql.array to pass in my custom objects array to the database. I know you can create it using the ArrayDescriptor class but the problem with that is the connection object is need.
I am using the writeSql() method of the SQLData interface. I therefore dont have the connection object. Any ideas?

haha
you misunderstand. i have in my code:
<code>
 // update the organisation
 public boolean setOrganisation(Organisation pOrg) {
 Organisation org = pOrg;
 OracleCallableStatement callStat = null;
 Connection conn = null;
 boolean OK = false;
 try {
 conn = getConnection(getUserName());
 pOrg.setConnection(conn);
 callStat = (OracleCallableStatement) conn.prepareCall("{call p_cmt.update_organisation(?)}");
 callStat.setObject(1, org);
 callStat.execute();
 OK = true;
 } catch (Exception e) {
 logger.severe("error writing organisation with id " + org.getId() + ". " + e);
 } finally {
 cleanUpConnections(conn, callStat);
 return OK;
</code>
This writes the object organisation to the database. Now in the class organisation i have the following method which is called automatically when writing the organisation object to the database:
<code>
 public void writeSQL(SQLOutput p_stream) throws SQLException {
 p_stream.writeInt(id);
 p_stream.writeObject(country);
 if (finIndexArr == null)
 finIndexArr = new ListElement[0];
 ArrayDescriptor af = ArrayDescriptor.createDescriptor(
 ObjectMapper.elementList, conn);
 ARRAY arr = new ARRAY(af, conn, finIndexArr);
 p_stream.writeArray(arr);
</code>
The problem is the last bit. To put the finIndexArr into an array i need the connection object. So i have to pass into the organisation object the connection object which seems unneccessary and pointless to me. I was just looking at an alternative way of creating the array without the need of the connection object. Since the setOrganisation() above has the connection to the database i dont see why i need to specify it in the array as well

Problem passing oracle.sql.ARRAY to Oracle

I am having ClassCastException when I try to pass a oracle.sql.ARRAY to a Oracle Package.
Here is my code:
PreparedStatement stmt = null;
String strArray[] = { "1,2,3,4,5" };
ArrayDescriptor descriptor = ArrayDescriptor.createDescriptor( "TEST_PAC_1.TEST_COLL_2", dbConnection );
//encounter Exception on the line below.
ARRAY array_to_pass = new ARRAY( descriptor, dbConnection, strArray );
String queryStr = "begin TEST_PAC_1.TEST_PROC_2(?); end;";
stmt = dbConnection.prepareStatement(queryStr);
stmt.setArray( 1, array_to_pass );
stmt.execute();
I understand that oracle.sql.ARRAY has been replaced by weblogic.jdbc.vendor.oracle.OracleArray in Weblogic.
MY QUESTION IS: HOW DO I INSERT MY STRING ARRAY INTO THE OracleArray and pass it to the plsql.
Really frustrated searching through the forums for the whole day,
Thanks,

Try this if you are at weblogic 8.1:
Connection con = getConnectionFromDataSource();
Connection vendorConnection = ((WLConnection)con).getVendorConnection();
// use direct oracle connection.
ArrayDescriptor descriptor = ArrayDescriptor.createDescriptor( "TEST_PAC_1.TEST_COLL_2", dbConnection );
vendorConnection.close();
Beware that you should be very careful as you are going to use a direct vendor
connection.
The better aproach is to pass the string array as a delimited string to your storad
procedure and parse it in the SP - then you don't have to mess up with vendor-specific
handling.
Hope this helps.

Oracle defined array type

Hi,
I am trying to pass an input parameter to a stored procedure as oracle defined array type. The input parameter will be stored as an array_varchar type which is defined by our own in our oracle 9i. Can anyone tell me how ? I've been looking for solution for 2 days and still dont know how.
Thanks.
yves

The solution described in Passing Array of UDT or Collection as IN OUT using OracleDbType.InputOutput
is working for me.

How to create Array type parameter of Oracle 10.2.0.1.0 in java

I create a collection type with:
CREATE OR REPLACE
type TEST_User.T_ARRAY AS TABLE OF VARCHAR2(100);
and in java code, I use following code to create a parameter of this type, and set it for a procdure
String[] userMakeArray = new String[]{"V", "N", "A"};
oracle.sql.ArrayDescriptor descriptor = oracle.sql.ArrayDescriptor.createDescriptor("TEST_User.T_ARRAY", cn); // cn is connection instance to database
oracle.sql.ARRAY array = new oracle.sql.ARRAY(descriptor, cn, userMakeArray);
((oracle.jdbc.OracleCallableStatement)call).setArray(8, array);
when i use this to call procedure in Oracle 10.1, it work well.
In Oracle 10.2, it does not work well.
For test, I can execute procedure well in sql plus, but in java client, I found that array contains three items "Null", while array is correct when conect to 10.1 enviroment.
does anybody know what's the reason for this.
thanks a lot.

insert into NSTableTab values (1,
NTab_Num(1, 2, 3, 4, 5, 6, 7, 8, 9, 10),
NTab_Vc2 ('One', 'Two', 'Three', 'Four', 'Five', 'Six', 'Seven', 'Eight', 'Nine', 'Ten'),NTab_Dat('01-JAN-2003', '02-JAN-2003', '03-JAN-2003', '04-JAN-2003',

Oracle.sql.BLOB array

Hi,
I have a database table(say MY_BLOB_TABLE.) having one blob column
I want to send each blob column as an attachment to a single email i.e. I for a particular case if I have 10 qualifying rows in MY_BLOB_TABLE,I want to send all these 10 blobs as different attachments with a SINGLE email.
I have the working code (from asktom) that allows me to send one attchment per email ..so I changed the code so that it takes array types to the things..
here is my code:
Database Type:
create or replace type xx_blobdata is varray(50) of blob;
create or replace type xx_attachedfile is varray(50) of varchar2(1000);
create or replace type xx_attachedfiletype is varray(50) of varchar2(1000);
Java Code
public class xx_attachments_mail
static String dftMime = "application/octet-stream";
static String dftName = "filename.dat";
public static oracle.sql.NUMBER
send(String from,
String to,
String cc,
String bcc,
String subject,
String body,
String SMTPHost,
oracle.sql.BLOB[] attachmentData,
String[] attachmentType,
String[] attachmentFileName);
PLSQL Wrapper
create or replace function xx_attachments_mail_send(
p_from in varchar2,
p_to in varchar2,
p_cc in varchar2,
p_bcc in varchar2,
p_subject in varchar2,
p_body in varchar2,
p_smtp_host in varchar2,
p_attachment_data in xx_blobdata,
p_attachment_type in xx_attachedfiletype,
p_attachment_file_name in xx_attachedfile) return number
as
language java name 'xx_attachments_mail.send( java.lang.String,
java.lang.String,
java.lang.String,
java.lang.String,
java.lang.String,
java.lang.String,
java.lang.String,
oracle.sql.BLOB[],
java.lang.String[],
java.lang.String[]
) return oracle.sql.NUMBER';
Actual Call:
attachment_data :=xx_blobdata();
attachment_type :=xx_attachedfiletype();
attachment_name :=xx_attachedfile();
ret_code := xx_attachments_mail_send(
p_from => '[email protected]',
p_to => '[email protected]',
p_cc => NULL,
p_bcc => NULL,
p_subject => 'testing',
p_body => 'testing..',
p_smtp_host => 'myserver.com',
p_attachment_data => attachment_data,
p_attachment_type => attachment_type,
p_attachment_file_name => attachment_name);
Everything compiles. All objects are valid in database.But when I call I get the following error:
ORA-29531: no method send in class xx_attachments_mail
ORA-06512: at "XX_ATTACHMENTS_MAIL_SEND", line 1
Can anybody point out what is wrong that I am doing.
Thanks.

Its already there...
public static oracle.sql.NUMBER send();
The code works well if I remove arrays (i.e. []) ... my problem is the mapping or VARRAY to Java datatype...
I just read something on oracle.sql.array ....that is the solution for mapping Oracle VARRAY to Java data type... but still I dont have a working code...
Any help is highly appreciated...
