Calling pl/sql package on different database in process flow

Hi there
Have a process flow which calls procedure on different database. This procedure truncates a table on the remote database.
Please could somebody confirm we would need to set up dblinks from the owf_mgr schema to the remote database.
New to wokflow - am i Correct in assuming the process flows run on the owf_mgr
rather than the control center owbrt.
Many Thanks

Hi there,
Thanks for the reply.
If my understanding is correct I could have a procedure as follows.
hkeeping.trunc_table@dblinkname('TABLE_NAME');
Is this the case?
Another alternative was to call directly the transformation in the process flow
e.g. we have pl/sql package on remote database whioch truncates the remote table.
When we try this with same procedure on same databas as owb user exists on then works fine.
However on remote database get message below. Does this mean anything to you? How could we sort this?
RPE-01003: An infrastructure condition prevented the request from completing.
  TEMP_PLOW:TRUNC_TABLE
Error
RPE-01038: Failed to evaluate expression null. Please modify the expression, redeploy and retry again.
   TEMP_PLOW:TRUNC_TABLE

RPE-02226: Cannot test Control Center user REMOTEUSERNAME. This user must match the login credentials of the deployment location.

Issue in Calling PL/SQL packages using callable statement

Hi ,
I have the requirement of calling two pl/sql packages , After call of first package is successful , i need to pass the output of that first package as input to second package.
Since i have called both the packages in same method of AM, first package gets executed successfully but second package doesnt get the input values required from first package and results in error.
Looks like since commit is happening in the single session second package is passed with NULL values.
Need suggestion for proper way of calling pl/sql packages when second package is dependant on first one:
Code used inside AM Method:
if("PENDING_XXX".equals(regVORow.getRegStatus()))
regVORow.setRegStatus("VENDOR_CREATED");
getOADBTransaction().commit();
OracleCallableStatement cStmt = null;
OADBTransaction dbTxn = getOADBTransaction();
NUMBER vendor_id = new NUMBER(-1);
NUMBER vendor_site_id = new NUMBER(-1);
int vendor_id_value = -2000;
String vendor_number = null;
try
cStmt = (OracleCallableStatement)dbTxn.createCallableStatement("begin *XXB_POS_PVT.create_vendo*r( p_vendor_name => :1, p_supplier_reg_id => :2, p_vendor_id=>:3); end;", 1);
cStmt.setString(1, regVORow.getSupplierName());
cStmt.setNUMBER(2, new Number(Integer.parseInt(supplierId)));
cStmt.registerOutParameter(3, 4);
cStmt.execute();
vendor_id = cStmt.getNUMBER(3);
vendor_id_value = vendor_id.intValue();
catch(SQLException e)
throw new OAException(e.getMessage());
Number vendorId = new Number(vendor_id_value);
regVORow.setVendorId(vendorId);
if(vendorId != null)
vendor_number = getSupplierVendorNumber(vendorId);
getOADBTransaction().commit();
AsiPosSupplierOpCosVOImpl regOpCosVO = (AsiPosSupplierOpCosVOImpl)this.getAsiPosSupplierOpCosVO1();
AsiPosSupplierOpCosVORowImpl row = null;
int fetchedRowCount = regOpCosVO.getFetchedRowCount();
RowSetIterator createIter1 = regOpCosVO.createRowSetIterator("createIter1");
if(fetchedRowCount > 0)
createIter1.setRangeStart(0);
createIter1.setRangeSize(fetchedRowCount);
for(int i = 0; i < fetchedRowCount; i++)
row = (AsiPosSupplierOpCosVORowImpl)createIter1.getRowAtRangeIndex(i);
if(row.getApprovalStatus().equalsIgnoreCase("HEAD_APPROVED"))
try
oadbtransactionimpl.writeDiagnostics(this,"Creating Site - " + vendor_id_value+" "+row.getSupplierOpcoCode()+" "+supplierId,1);
cStmt = (OracleCallableStatement)dbTxn.createCallableStatement("begin *XXB_POS_PVT.create_vendor_sites*(p_supplier_reg_id => :1, p_vendor_id=>:2, p_opco_code=>:3, p_vendor_site_id=>:4); end;", 1);
cStmt.setNUMBER(1, new Number(Integer.parseInt(supplierId)));
cStmt.setNUMBER(2, new Number(vendor_id_value));
cStmt.setString(3,row.getSupplierOpcoCode());
cStmt.registerOutParameter(4, 4);
cStmt.execute();
vendor_site_id = cStmt.getNUMBER(4);
getOADBTransaction().commit();
catch(SQLException e)
throw new OAException(e.getMessage());
createIter1.closeRowSetIterator();

Hi ,
There are some validation that can be performed from Entity level ( EO ) , you can go through them in Jdev guide .
It depends on the business requirement , not all validation can be performed from Entity level .
Let us know your business requirement , will try to clear your doubt .

Calling PL/SQL Package in the same connection

I have a PL/SQL Package MYPCKG, stored in the database, with a function GETDFLT(). I need it to initiate the default values for fields (Attributes) of an EntityImpl Object (EOImpl) in its create method.
I used JPublisher to generate a wrapper class of the package, named MyPckg. It has three Constructors: MyPckg (),MyPckg (ConnectionContext c) and MyPckg (Connection c). The problem is that I dont know how to use the existing connection of EntityImpl object (or of ApplicationModuleImpl) to create a new MyPckg object.
The example below makes a new connection to database:
public class EOImpl extends oracle.jbo.server.EntityImpl {
public void create(AttributeList attributeList) {
Oracle.connect("jdbc:oracle:thin:@host:1521:DB1", "user", "pwd");
MyPckg dflts = new MyPckg ();
setField1 (dflts.getDflt ());
I believed that I can do it through DBTransaction but I couldnt find a relationship between DBTransaction and java.sql.Connection or sqlj.runtime.ConnectionContext.
In MetaLink, I found a couple of items with the same problem, but they appear not to be answered.
Thanks in advance

Thank you very much for replay.
The suggested technique uses JDBC. In fact, I wanted to use BC4J Entity Object and embedded SQLJ (generated by JPublisher). In the JDeveloper Help Topic Embedding SQL in Java Programs with JDBCstays: JDBC provides Java programs with low-level access to databases. If your application or applet uses purely static SQL, where you know the database schema at compile time, you should consider using SQLJ instead. So what I am looking for is how to get a java.sql.Connection or sqlj.runtime.ConnectionContext or sqlj.runtime.ref.DefaultContext Object from some BC4J Object (ApplicationModule or Entity).
Thanks in advance

Updating pl/sql package after major database changes

Hi,
This thread to know if there is any utility which allow to impact changes made on a database, on the pl/sql packages. I have a datawarehouse, which was partially rebuild, a lot of tables have changed name etc... All the data of this DWH is load and treated with pl/sq procedures, and i would like to know if there is any utility, or if you have any advices or workaround to easily impact those changes on the pl sql packages. (Please forgive me for my very bad english.). Thanks by advance

I haven't explored too much about this SQL Developer Data Modeler tool, but so far from my experience using it, this tool is not better than Oracle Designer in the Oracle Dev Suite 10g.
Therefore, I don't think this tool is capable doing that "magic" think to automatically remap the packages after DDL (maybe wrong).
Not sure if the more expensive tools like TOAD Data Modeler or ER Win can do this.
Perhaps you can write DDL Triggers to automatically capture whenever there is any modification in your tables.

Call PL/SQL Package to Create DB User and assign Privileges

Hi All,
I'm sure this has been covered before but I couldn't find anything relevant....
I'm calling a PL/SQL Process from within an Apex (version 2.0) Page, that ultimately Creates a New DB user.
I am receiving an ORA-01031: insufficient privileges error. My Application User and the Package owner both have privileges to Create a DB user.
What am I missing?
Thanks,
Mike

Never, ever grant additional privileges to the apex_public_user account. It achieves nothing and makes the account over-privileged. The only privilege it needs is CREATE SESSION.
Mike - Your application's parsing schema (I assume that's the package owner) needs to be granted privileges directly and not through roles. I don't know what you mean by your application user's privileges. Those users are not database accounts (unless you are using a dedicated DAD, etc.).

Comparing PL/SQL code from different database

Hi,
I have 3 databases(development, test and production) lying in 3 different servers. I wanted to check if all the databases have the same PL/SQL code.
is there a automatic ways of doing that. If not is there any best practices that can be followed
I use oracle 10g
Thanks,
DJ

Dont you have a Change Management System in place. How do you do your deployment. What is the versoin control system you use?
When you deploy your code in some database dont you store the details some where?
In database source code is available at ALL_SOURCE. You can query that and compare. But its never a good idea.

here If the db is sybase should run sybase ddl only and visa-ver.
Please help

Its already there, but you have any though on same file please write.My thoughts is that it sounds like a bad idea. Do you have a particular reason for wanting this in a single file?

Generating Java wrappers for PL/SQL Packages in JDeveloper 3.1

I have not been successful in using JD3.1 to generate java classes for use in calling PL/SQL packages from a Java Servlet I am developing. I have followed the directions under the 'Generating Java Code for Oracle Objects and PL/SQL Packages' help topic: I display the package in the database browser window, right click on the package, select 'Generate Java', and click 'OK' on the pop-up JPublisher window that appears. The wizard clocks out for a few moments, then the JPublisher window disappears, but the java class is not added to JDeveloper's Navigation pane for the Project and Package I specified in the wizard.
Any idea where the generated class is going to?

should be, but isn't... JDeveloper3.1
(build 681) default install... Is it in
a custom package I didn't install? Or
am I just a dumb nut?Hmm.. I thought it was in there.. JPub is a java based tool. You can invoke it as such.
1st, use setvars.bat from your jdeveloper/bin directory.
2nd, run java oracle.jpub.java.Main (pass it the same arguments as you would the jpub.exe)
Here's the output from my machine here:
D:\JDeveloper31\bin>setvars D:\JDeveloper31
Setting JDeveloper 1.2 runtime environment to "D:\JDeveloper31"
Setting JDK version 1.2 in "D:\JDeveloper31\java1.2"
D:\JDeveloper31\bin>java oracle.jpub.java.Main
JPub: Java Object Type Publisher, version 8.1.6.0.0 Production
(and the rest of the help)
Take Care,

ESB cannot find SQL package

Hey I have an ESB service which calls a DBadaptor which calls a SQL package, but for some reason it cannot find the package at runtime.

Some more information would be really handy.
- Did it work in the first place?
- Did you deploy to another environment?
- Are there other people working in the same environment? e.g. Did someone remove something you are not aware of?
- Did you check the various logfiles for errors. What errors are you receiving?
- When you login to the database with e.g. SQL Developer. Can you actually find the Object in the first place?
etc :-).
More information would really be appreciated :-)

How to get changes of a custom PL/SQL package updated in ISG?

Hi All,
I need some help on how to change a custom PL/SQL package in ISG integration repository:
I already uploaded my custom PL/SQL package to the integration repositoy some time ago. Now I have made some changes to PL/SQL record/table types defined in the package (added some fields and removed some others). These changed record/table types are used by a procedure I already uploaded to the integration repository. When regenerating the WSDL for my PL/SQL package in integration repository I get an error that the wrapper for respective procedure can't be found. When checking up the SQL types that were automatically generated (by JPublisher) for corresponding PL/SQL types, these generated SQL types are invalid...
So it seems that in one case JPublisher generated an empty SQL type (with no attributes). In another case JPublisher generated the SQL type with old attribute list, so it didn't adopt the changes of corresponding PL/SQL type in the package...
Can anybody tell me how to get the changes of a cusotm PL/SQL package updated in ISG? Or is there any possibility to first remove a whole PL/SQL package from the ISG integration repository (and getting rid of all old automatically generated SQL types), so that I can newly upload my PL/SQL package afterwards?
Thanks
Konrad

Thanks Daniel, for your reply...
(-> for info: I'm a colleague of Konrad...)
Yes, we used a higher version number - and the upload of iLDT file works fine...
But, the problem occured when generating the WSDL...
However, I think we have found an approach of how to get the changes of a custom PL/SQL package updated correctly in ISG:
1. Save a copy of PL/SQL package and then delete it in the database
2. Regenerate the WSDL for PL/SQL package in ISG (seems that all atutomatically generated JPub wrappers and SQL types are also deleted)
3. Restart all processes
4. Create the changed version of PL/SQL package in the database again
5. upload of iLDT
6. Regenerate the WSDL for PL/SQL package in ISG
Best Regards
Carolin
