Server side procedure

Hello!
I'm upgrading some forms to 6i.When compiling a library I receive an error like this: 'Can't call builtin routines remotely. I have understood that DBMS calls are not supported in client-side PL/SQL code. I receive the error message in the following code:
lp_msg.display('FRM_SAVE_TO_FILE_FAILED', chr(10) || sys.dbms_utility.format_error_stack, TRUE);
To avoid this problem I think I have to create a server side procedure that calls the DBMS_UTILITY.
Will the following code do this job and do I have to delete the code from the client form? Any other suggestions of how to solve this problem?
procedure test_1 is
lp_msg.display('FRM_SAVE_TO_FILE_FAILED', chr(10) || sys.dbms_utility.format_error_stack, TRUE);
END;
Thanks in advance
Regards

Calling server side procedures from forms

Hi
I am trying to add a server side procedure to a form. The procedure is held in a package which resides on a remote database and I have set-up database links to this database.
When I run the form, calling the procedure, the oracle forms runtime session closes without displaying any error messages.
I have successfully called the procedure from database triggers in different databases.
Does anyone know whats going on?
I am using forms 5.0 with a oracle 7.3 database
Thanks!!

Check out the method:
LibraryObject.invokeServerMethod(String, Serializable)
I think this may be exactly what you're looking for.

Is there a way to dynamically determine the number of out parameters for a server side procedure?

Hi,
Below is a helper method used for calling a server-side function which loops through the inbound bindVars parameter to populate the function's IN parameters. Is there a way to dynamically determine the IN/OUT parameters based on the procedure name in the stmt parameter? No members of the CallableStatement class seemed promising, but the getParameterMetaData() method in the PreparedStatement class seemed like it could be helpful lead. However, I have not found any detailed descriptions (yet) of how to use it.
protected Object callStoredFunction(int sqlReturnType, String stmt,
Object[] bindVars) {
CallableStatement st = null;
try {
// 1. Create a JDBC CallabledStatement
st = getDBTransaction().createCallableStatement(
"begin ? := "+stmt+";end;",0);
// 2. Register the first bind variable for the return value
st.registerOutParameter(1, sqlReturnType);
if (bindVars != null) {
// 3. Loop over values for the bind variables passed in, if any
for (int z = 0; z < bindVars.length; z++) {
// 4. Set the value of user-supplied bind vars in the stmt
st.setObject(z + 2, bindVars[z]);
// 5. Set the value of user-supplied bind vars in the stmt
st.executeUpdate();
// 6. Return the value of the first bind variable
return st.getObject(1);
catch (SQLException e) {
throw new JboException(e);
finally {
if (st != null) {
try {
// 7. Close the statement
st.close();
catch (SQLException e) {}

The PreparedStatement.getParameterMetaData() object is exactly what you need for this task.
Once you have the ParameterMetaData you can ask it how many parameters are present and which mode they are. The parameters are numbered from 1 to n and you can use ParameterMetaData.getParameterMode(1); to get the mode of the 1st parameter. The modes are defined as static values in the ParameterMetaData object. Check out the doc at http://docs.oracle.com/javase/7/docs/api/java/sql/ParameterMetaData.html

Java Stored Procedure / connection JDBC / Server Side / Client Side

Hi,
I would like to know if we can know at the runtime with a JDBC api if the stored procedure is running in client side or in server side ?
THANKS

You wrote
"Java stored procedures -- by definition - are stored in the 8i rdbms. !!"
From the Oracle8i Java Stored Procedures Developer's Guide
Release 8.1.5
A64686-01
"If you create Java class files on the client side, you can use loadjava to upload them into the RDBMS. Alternatively, you can upload Java source files and let the Aurora JVM compile them. In most cases, it is best to compile and debug programs on the client side, then upload the class files for final testing within the RDBMS"
This means that you can create shared classes that are used on both the client and server side. The source does not need to reside within the server (according to their documentation). Please also note the following from the Oracle8i JDBC Developer's Guide and Reference Release 8.1.5 A64685-01 for using the getConnection() method on the server:
"If you connect to the database with the DriverManager.getConnection() method, then use the connect string jdbc:oracle:kprb:. For example:
DriverManager.getConnection("jdbc:oracle:kprb:");
Note that you could include a user name and password in the string, but because you are connecting from the server, they would be ignored."
So if you're coding a shared class that is to run on both the client and server side, you might do something like this:
Connection conn =
DriverManager.getConnection(
System.getProperty("oracle.server.version") == null
? "jdbc:oracle:thin:@hostname:1521:ORCL"
: "jdbc:oracle:kprb:"),
"youruserid","yourpassword");
As stated earlier, the userid and password are supposedly ignored for server connections retrieved in this manner. I haven't tried this yet, but it is documented by Oracle.

Run a procedure server-side?

hi all,
how do i execute a procedure (which takes a very long time to run) server-side? since this procedures takes a long time, i want it to continuously run and finish even if i close and shutdown the client machine that invoked it.
thanks
allen

hi,
thanks for the replies.
actually this is kinda like an end of day or end of month procedure so naturally it would take a long time which is understandable.
i'll check out the job option. although if there are still some other options, i'm willing to listen.
thanks.

Problem inserting records after execution of server side code

Hello,
I've created a server-side function for duplicating a master record and it's details. This function has two input parameters that define the new unique key of the master record. Because the user has to supply the new unique key, there is a possibility that the unique key already exists.
The server-side function is being called from a form module. This form module contains all the code needed for opening / closing and aborting the HSD transaction. The form also enables users to add new master records manually.
If the server-side function is called from within the module there are two possible outcomes:
1, the unique key already exists and the HSD error message window is displayed.
2, the unique key does not exist and the records get duplicated.
If I try to add a new master record in the form after a failed duplication process, I get a form message informing me that NULL cannot be inserted into the ID column. (The primary key.) BTW updates work just fine. However, if I call the server-side function again and the duplication process is succesfull, I can again insert a new master record in the form succesfully.
I'm assuming that this problem has something to do with the TAPI package because I use TAPI insert calls to insert the master / detail records when duplicating. A workaround for this problem is (obviously) to check if the supplied unique key already exists in the database before calling the server-side function.
I however am concerned a bit because a lot of program functionality has been implemented in server-side functions and procedures. So I would like to know if anyone has had the same problems and possibly knows if there is a generic solution to this problem.
Greetings,
Marco.

Marco,
Can you make a test case for me and send it to me? It looks like we might have a bug and I would like to investigate.

How to create an object alive all the time on a server side

Hi,
I work on an Intranet with J2EE technologies. I need an object to do several tasks in background on the server side. Like start scheduled processes on a database and files, stocked on the server. What is the way to do this. I thought to use the JNDI by declaring the object in the Deployement Descriptor, and to manage a timer within.
I don't know if this works.
Anyway, my question is how to create an object on the server that is ALIVE ALL THE TIME and visible by the other objects running in the same VM.
Thank's.

This may not be the correct design, but I had success doing the following:
1. Create an Stateless EJB that does a task, i.e. update a database table.
2. Create a subclass of java.util.TimerTask to call the EJB methods.
3. Kick off the TimerTask from a servlet.init method.
Seems to work pretty well to do scheduled tasks, such as refreshing lookup tables. I would imagine the same could be done with an MBean, but I haven't had time to fully understand JMX yet. (It's on the list).
As for event driven procedures, that can be done through a servlet interface.
You may also wish to review a scheduler here: http://www.part.net/quartz.html. Note, I have NOT even looked at it yet, so I have no clue if it's any good. But, it is on my list of tools to evaluate (that's a long list) someday when my head's above water. Have a look, and caveat emptor.
Hope this helps,
Perry Tew

Calling PL/SQL from Server Side Rule

Hi there,
I'm wanting to call a PL/SQL procedure from a server side rule created within collaboration suite using the oesrl command line utility. I have seen examples of the XML rule which should do this together with the appropriate PL/SQL
<account qualifiedName="UM_SYSTEM" ownerType="system">
<rulelist event="relay">
<rule description="Retention Rule" active="yes">
<condition negation="no" junction="and">
<condition>
<attribute tag="rfc822to"/>
<operator caseSensitive="no" op="contains"/>
<operand>instigate.com</operand>
</condition>
</condition>
<action>
<command tag="call"/>
<parameter>RulesPackage.archive_message</parameter>
<parameter>test1</parameter>
<parameter>Archive</parameter>
</action>
</rule>
</rulelist>
</account>
The above should call the Procedure RulesPackage.archive_message when an email to anyone at instigate.com arrives in OCS. I have written and tested an appropriate package. However, I have been unable to get the rule to execute and call my PL/SQL when I send an email to trigger it.
I have written rules which do not invoke external packages without any trouble.
I believe the problem is that I need to register the PL/SQL package with the rules engine somehow, before the rule can find it, but I am uncertain how to do this, or even if that is indeed what I need to do.
Any help would be most appreciated as the documentation doesn't go into too much detail.
I am using OCS R2.
Regards
Oliver

Could you please check the structure of the procedure "RulesPackage.archive_message" ? It may fail due to procedure structure.
The structure should be similar to the below example
PROCEDURE archive_message
(p_event IN NUMBER,
p_sessionid IN NUMBER,
p_msgobj IN es_mail.mail_message_obj,
p_param1 IN VARCHAR2,
p_param2 IN VARCHAR2,
p_status OUT NUMBER) AS
BEGIN
/* Code for Archving */
END;

How to run a SQL server store procedure from Apex (oracle)?

Our application needs to call a store procedure in the SQLserver database. The sotre procedure works fine in the SQL server side. However, when I tried to call the store procedure in TOAD as:
exec my_store_procedure(para1, para2);
I kept getting the error message:
ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'my_store_procedure'
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
I have searched online but couldn't find the solution. This is an emergency, so prompt reply is Highly Appreciated!

I don't think that Generic Connectivity supports stored procedures.
The documentation for Heterogeneous Connectivity is here:

Server-side filtering to subfolder for all users (spamassassin)

Hello,
I am trying to integrate a 3rd-party spam filter/virus scanner, it is just spamassassin/amavisd-new running on a front-end box that adds an X-Spam-Flag: YES header to the message before passing it on. This works great on our current postfix/cyrus-imap system using individual cyrus sieve server side filters to look for the flag and move the message into the user's spam folder.
My question is how to do this in a universal way on OCS, I have been reading through the docs and think server-side filters are the answer, but I can't seem to find a way to set up a system-wide filter that will put the incoming message into the recipients' spam subfolder. Does anyone have any clues on this? I think the key here is to somehow be able to use the recipient name as a variable to pass as a parameter to the moveto action, but I can't see a way to do this. Any pointers would be appreciated.

You can do this in a single system wide rule, but it's undocumented and technically unsupported.
First of all, checking the spam-flag in a system side Deliver rule is straightforward:
<condition>
<attribute tag="xheader" param="X-Spam-Flag"/>
<operator caseSensitive="no" op="stringequal"/>
<operand>YES</operand>
</condition>
(Checking on the subject is OK too, if you rewrite it through SpamAssassin.)
Then to move to a folder, you'll need an external PL/SQL action since the full folder name will vary for each user:
<action>
<command tag="call"/>
<parameter>SpamCheck.moveMsg</parameter>
<parameter>parameter1</parameter>
<parameter>parameter2</parameter>
</action>
Then the tricky part is the Pl/SQL to do the move, using the undocumented es_ga.g_username variable. This is the only way to know which mailbox context you're currently in for the deliver event at the system level. Without this, you need a separate rule for every user. Here's the bare bones of a procedure that would do it.
procedure moveMsg(p_eventid in integer,
p_sessionid in integer,
p_msgobj in mail_message_obj,
myparam1 in varchar2,
myparam2 in varchar2,
p_status out number)
is
this_user varchar2(255);
mList MAIL_MESSAGE_LIST;
Begin
this_user := es_ga.g_username;
mList:=MAIL_MESSAGE_LIST(p_msgobj);
mail_folder.move_messages(p_sessionid, mList, '/' || es_ga.g_username || '/ServerMove');
end MoveToSpam;
You probably want to add some exception handling, etc. to that ;-) More info on the Pl/SQL API in general is in the Mail Application Dev Guide.

SQL Server Stored Procedure to Oracle

Hi All,
I have a store procedure in SQL Server(2005 onwards)...I need to convert that in Oracle. As I am new to Oracle. Please guide me.
I have two tables MetaDatabase and MetaEntity. The store procedure loads the MetaDatabase and MetaEntity based on MetaDatabase...As of now it is hardcoded in SP...
MetaDatabase
CREATE TABLE MetaDatabase
ID INT NOT NULL,
Alias VARCHAR(64) NOT NULL,
VersionMajor smallint NOT NULL,
VersionMinor smallint NOT NULL,
VersionRevision smallint
INSERT INTO MetaDatabase VALUES(1, 'DB1', 1, 1, 1);
INSERT INTO MetaDatabase VALUES(2, 'DB1', 1, 1, 2);
INSERT INTO MetaDatabase VALUES(3, 'DB2', 1, 2, 1);
MetaEntity
CREATE TABLE MetaEntity
ID INT NOT NULL,
MetaDatabaseID INT NOT NULL,
Name VARCHAR(64) NOT NULL
INSERT INTO MetaEntity VALUES(1, 1, 'TABLE11');
INSERT INTO MetaEntity VALUES(2, 1, 'TABLE12');
INSERT INTO MetaEntity VALUES(3, 2, 'TABLE21');
INSERT INTO MetaEntity VALUES(4, 2, 'TABLE22');
INSERT INTO MetaEntity VALUES(5, 3, 'TABLE31');
INSERT INTO MetaEntity VALUES(6, 3, 'TABLE32');Here is the SP as of now I am loading 2 MetaDatabase out of 3.
CREATE Procedure myProc
AS
     DECLARE @tmpDictionaries TABLE ( Alias varchar(64),
                                      VersionMajor smallint,
                                      VersionMinor smallint,
                                      VersionRevision smallint )
     DECLARE @tmpMetaDatabase TABLE ( ID int PRIMARY KEY )
     DECLARE @tmpMetaEntity    TABLE ( ID int PRIMARY KEY )
    /* Load these 2 MetaDatabase */
    INSERT INTO @tmpDictionaries (Alias,VersionMajor,VersionMinor,VersionRevision) VALUES ('DB1',1,1,1)
    INSERT INTO @tmpDictionaries (Alias,VersionMajor,VersionMinor,VersionRevision) VALUES ('DB2',1,2,1)
    /* Make sure that all passed in dictionaries actually exist */
    IF (SELECT COUNT(*) FROM @tmpDictionaries t WHERE NOT EXISTS(SELECT ID FROM MetaDatabase md WHERE md.Alias=t.Alias AND md.VersionMajor=t.VersionMajor AND md.VersionMinor=t.VersionMinor AND md.VersionRevision=t.VersionRevision)) > 0 BEGIN
      RAISERROR ('Not all dictionaries requested exist', 16, 1) WITH SETERROR
      RETURN
    END
    /* remember the MetaDatabase records */
    INSERT INTO @tmpMetaDatabase    SELECT ID FROM MetaDatabase md WHERE EXISTS(SELECT * FROM @tmpDictionaries t WHERE md.Alias=t.Alias AND md.VersionMajor=t.VersionMajor AND md.VersionMinor=t.VersionMinor AND md.VersionRevision=t.VersionRevision)
    /* remember all related MetaEntity records */
    INSERT INTO @tmpMetaEntity      SELECT ID FROM MetaEntity me    WHERE EXISTS(SELECT ID FROM @tmpMetaDatabase t WHERE t.ID=me.MetaDatabaseID)
    /* return all MetaDatabase */
    SELECT md.* FROM MetaDatabase md WHERE EXISTS(SELECT ID FROM @tmpMetaDatabase WHERE ID=md.ID)
    /* return all related MetaEntity records */
    SELECT me.* FROM MetaEntity me WHERE EXISTS(SELECT ID FROM @tmpMetaEntity WHERE ID=me.ID)Here is the output I get..It returns 2 resultsets one for each SELECT in SP.
EXEC myProc
1     DB1     1     1     1
3     DB2     1     2     1
1     1     TABLE11
2     1     TABLE12
5     3     TABLE31
6     3     TABLE32I need same in Oracle..where I can parse the resultset returned from SP. Any help will be greatly appreciated.

PL/SQL is two languages:
- a procedural language called Programming Logic - which has its roots in the Ada and Pascal family of procedural languages.
- the SQL language.
These are tightly integrated to allow you to use SQL natively inside PL. In other words, you can mix SQL source inside PL source code, reference PL variables in SQL source and the PL compiler and run-time is clever enough to know what code is PL and what code is SQL and how to glue the SQL into the PL.
Bottom line - PL is not a macro/scripting language for running SQL. It is equivalent to to Java, C#, Visual Basic and others ito features and how one designs and uses the language.
So your question of how to covert a T-SQL proc to PL/SQL is equivalent of asking how to change a T-SQL proc to C/C++ using the Pro*C (embedded SQL) compiler.
So please - forget any notion that PL/SQL is like T-SQL. Or even that Oracle is at all like SQL-Server. Oracle is "+that darn good+" not because it emulates SQL-Server.. but because it is not like SQL-Server. It is the differences in the feature set of Oracle from SQL-Server that sells Oracle.
I need same in Oracle..where I can parse the resultset returned from SP. Any help will be greatly appreciated.Oracle does not work this way. There are also no "result sets" in terms of a temporary data set that's created in the server and stored in memory. This type of approach does not scale if you have a 1000 users all running the same application code and all attempting to create "result sets" in server memory at the same time.
The norm for client-server code using PL/SQL as the server side interface into database data, is for the PL/SQL code to create a SQL cursor and return a pointer (called a reference cursor handle or simple a reference cursor) to the client.
The client (e.g. VB/Java/C#/Delphi/etc) can then fetch data from the SQL cursor (a "program" in server memory that finds and retrieves the relevant rows).
To understand and "enjoy" Oracle, one needs to empty one's cup of SQL-Server/DB2/Informix/whatever in order to fill that cup with the Oracle brew. Only then can one really taste and enjoy Oracle. So, think twice before assuming Oracle is like SQL-Server and PL/SQL is like T-SQL. You will save yourself a lot of frustration, wasted effort, and run into fewer (very hard and very painful) brick walls as a result.

Server side rule and procCall - only in es_mail schema

I am trying to call procedures in the procCall tag of a server side rule, but I cannot make it work for procedures that are not in the es_mail schema.
I tried creating synonyms and I am dead sure my grants are correct, but as soon as I add a schema name in front of the call it stops working.
Is this correct, people of Oracle, and why?
Wendy

The IMAP-protocol (I suppose that's the one you use, otherwise server side mail filtering won't be visible in Mail.app) does not have any mechanism to transmit colorization information to the client. You have to set up these manually on each client.

SQL Server Stored Procedures

Is there a way of firing up SQL Server stroed procedures from
Flash 8?
If so could someone explain how to do it please, as I would
like to pass parameters from choices made via drop down lists
(populated from xml pages) to query a SQL Server 2000 database.
Any help appreciated.
Thanks

Yes, I understand. But Flash doesn't talk directly to your
SQL API.
The SQL interface is only available through ASP (in your
case, or any number of server-side technologies). That's why you
use getUrl() (or other http request) to send data to an ASP script
which then executes the SQL statement 'execute <blah>
<blah> <blah>'.
You then take the results of that SQL, format it, and return
something to Flash all as part of the one and only HTTP request.
Does this make sense?
