How to call external Perl routines from Pl/SQL - Urgent

Available software in the Test Environment:
1. Sun Unix 2.8
2. Oracle 8.1.7 ( 8i)
3. Perl 5
Iam trying to call/execute perl scripts from PL/SQL using the DEMO_RDBMS.mk. I am able to call C scripts from PL/SQL, but actually want to call Perl scripts.
The steps followed for for C are -
1. Create and compile a simple C program to execute a unix command (eg., touch a file).
2. Make a shared library of the above compiled program (object), i.e., load the compiled object module into a dynamic load library.
3. Declare the above library in Oracle using SQL*Plus.
4. Define a PL/SQL function or procedure to call the external routine.
5. Test the external routine.
The above steps run good for a C program, but step 2 fails when run for a Perl script.
When I tried to use the following command for step 2 -
make -f $ORACLE_HOME/rdbms/demo/demo_rdbms.mk extproc_callback \
SHARED_LIBNAME=cmd_lib.so \
OBJS=tst_cmd.pl
got the following error -
ld: fatal: file tst_cmd.pl: unknown file type.
ld: fatal: File processing errors. No output written t cmd_lib.so
*** Error code 1
This gives me an indication that demo_rdbms.mk does not understand/interpret Perl scripts. Going through the demo_rdbms.mk suggests the same.
My questions is - How do we call external Perl scripts/routines from PL/SQL ??
Do I have to get a different version of "demo_rdbms.mk" ?
PS: The perl scripts used above (tst_cmd.pl) is error free and works as intended in the unix environment.

Iam trying to call/execute perl scripts from PL/SQL using the DEMO_RDBMS.mk. I am able to call C scripts from PL/SQL, but actually want to call Perl scripts. Well, C is a "compiler" language and Perl is interpreted. In a sense, C is not "scripts".
When I tried to use the following command for step 2 -
make -f $ORACLE_HOME/rdbms/demo/demo_rdbms.mk extproc_callback \
SHARED_LIBNAME=cmd_lib.so \
OBJS=tst_cmd.pl
got the following error -
ld: fatal: file tst_cmd.pl: unknown file type.
ld: fatal: File processing errors. No output written t cmd_lib.soI guess this compiles an extproc "stub" with your object file, generating an external procedure. So the object file really needs to be an object file :-)
My questions is - How do we call external Perl scripts/routines from PL/SQL ??I'd guess you need an embedded Perl interpreter in the external procedure.
Not much help though I'm afraid :-/

Problems calling external C routines from PL/SQL

Hi everybody!
I'm not familiar with C programming in Unix, but I'm trying to make work an example to execute external procedures (developed in C) from PL/SQL.
The example includes .c and .pc source files, which I have compiled succesfully.
After that, links the .o files into .so to declare later as libraries in the Oracle database.
The problem appears when I try to execute this procedures (from PL), when a I get the error:
"Error loading external library"
"ORA-06522: ld.so.1: ORACLE_HOME/bin/extprocPLSExtProc: fatal:
relocation error: file /opt/mqm/lib/libmqm.so: symbol NULL_HSHMEMS: referenced symbol not found"
The library /opt/mqm/lib/libmqm.so is provided with the installation of MQSeries Server.
Thanx in advance.
Luisa.

Here is what works on my system:
TNSNAMES.ORA:
EXTPROC_CONNECTION_DATA.WORLD =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
LISTENER.ORA:

Calling a Perl code from pl sql

Hi,
I have to carry out a process -wherein - i need to execute 2 plsql procedures and a perl function in between the two. The first pl sql procedure creates a file - which needs to be worked on by the perl file and processed and the resulting file is used by the second and last pl sql procedure. Is there any way to pull this off?
thanks

I would seriously question the architecture here... That being said, depending on the Oracle version,
1) A shell script/ external process could
- invoke SQL*Plus, run the first procedure
- Call the Perl script
- invoke SQL*Plus, run the second procedure
2) The Perl script could do the same thing (i.e. connect to the database, run the first procedure, process the file, run the second procedure)
3) A SQL*Plus script could connect to the database, run the first procedure, use the HOST command to invoke the Perl script, and then call the second procedure.
4) A Java stored procedure could call out to the operating system to invoke the Perl script and a PL/SQL procedure could then invoke procedure 1, this new Java stored procedure, and then procedure 2.
5) (10g and later) You can call procedure 1, then create a one-time DBMS_SCHEDULER job that calls the perl script, then call procedure 2.

How to call a perl module from Java program.

Hi,
I create a simple java program as follows
class test{
public static void main(String args[])
{try {
Runtime r = Runtime.getRuntime();
r.exec("perl test.pl");
catch(Exception e)
{e.printStackTrace();}
and test.pl is located in the same directory as the java program. The program compiles but with no return as I execute it. I am not sure what is wrong.
Thanks,

I think the wrong line is here; r.exec("perl test.pl");
Usually the JVM needs the full path.If the path for either the executable or the script was wrong then, given the code posted, it would not hang.
>
To automatticaly get the path (if the file is in the
class path) use
System.getProperty("java.class.path")
That gets paths(plural).
Try this:
r.exec("perl " +
System.getProperty("java.class.path") + "\test.pl");I am rather certain that that won't work on any standard operating system.

Calling external C procedures from PL/SQL

Hello,
The first two development steps for external C procedures are:
1. Create and compile the external procedure in 3GL.
2. Link the external procedure with the standard shared library at the operating system level.
For others, for example for 3. Create an alias library schema object to map to the operating system's shared library, i can see details of how to do this, but for first two, i see "Varies for each operating system; consult documentation".
My question is, how can 1 and 2 be done, in case of Windows? So i have the .c file, where i've written a procedure. And next what should i do for the first two steps?
Thanks

How to call external application (transaction launcher) from event method

Hi all
Can somebody tell me which program lines to put into an event handler method in a view controller to get an external application called. I intend to define the link to the external application in the Transaction Launcher. But I cannot find any instructions on how to call the Transaction Launcher from my event handler method. I do not want to launch the application from the navigation bar, ONLY via a link in a list of invoices in a table view, and I want to press the invoice number to get an external application called to display the invoice. My event handler method gets called fine enough, but I have no clue which program lines to put into the method to pass on the call to the Transaction Launcher
Best regards

I want to call External Java class from the PL/SQL

Hi,
I am using Oracle Apps R11i (11.5.7), I wanted to call external Java class from the PL/SQL. This external Java class is residing in another application server.
How do I do this.
I know one way. Develop C routine in Oracle Apps to call external java class and call this C routine from the PL/SQL.
Is there any simple method available? or any other method?
Thanks in advance.
-Venkat

First of all, this is a Java application you're talking about, right (i.e. it has a main() function)? It's not just a class that you're trying to instantiate is it? If it's an application, you obviously have to start a new virtual machine to run it (rather than using the virtual machine built into the database like stored java). I'm a little leary of your mention of an "application server" as this would more commonly mean that a virtual machine is already over there running with access to this class. In which case, you'd typically interface with SOAP or some other RPC API.
All that aside, as long as you have physical disc access (through NFS or whatever) to the class file, you could use a java wrapper class with a system call to do this. In fact, there is a thread in just the last day or so on this very forum that has the code to do just that (see " Invoking OS Commands from PL/SQL"). However, it's worth noting that the virtual machine will be running on the database server in this case and not the application server.
