Out Variable of PL/SQL into UNIX environment

Hallo,
I'd like to pass an out variable from a PL/SQL package to an UNIX environment!
Is this possible?
Thanks,

Hello Shankar,
Thank you for your instant reply.
Thanks to you, I can write the sample code that works fine.
I understand that calling setMaxParamSize() before calling setString() is very important.
Below is the final sample code that works fine.
std::string sql4 = "BEGIN test4_proc(:1); END;";
std::string result;
Statement* stmt4 = conn->createStatement(sql4);
stmt4->setMaxParamSize(1, 12); // Important!! Call before setXXX()
stmt4->setString(1, "Hello");
stmt4->executeUpdate();
result = stmt4->getString(1);
std::cout << "result : <" << result << ">" << std::endl;
Thank you.

Handling variable flat file name in UNIX environment

Dear Forum,
I am working in a project where,
Online systems generate flat files with variable names (followed by timestamp) and load into a Unix directory (FTP Location) for loading into data warehouse.
Using OWB, I will have to rename those files into a static name then execute the mapping. Once the mapping is executed the the source file should be transfered to a different directory.
I am trying to do this using a external process in OWB process flow. I found a similar reference in the link below
http://www.oracle.com/technology/products/warehouse/pdf/Cases/case7.pdf
But here it is shown for windows only. As I do not know unix, I could not proceed a lot with this.
Therefore requesting you all, please help me showing how can I achive this. I think your answer will help many others along with me, looking for the same solution. Please help.

You will need to logon as your Oracle owner (the userid is ORACLE, in my case), and then issue the following commands from a terminal session:
To create a new reports server (one in addition to the default
in-process server), use the following commands:
export ORACLE_HOME=<whatever your oracle home path is>
cd $ORACLE_HOME/bin
./rwserver.sh <newserver name>
To start the new server, issue:
./rwserver.sh server=<newserver name>
Leave the Unix session that was used to start the server logged on unless you have something like DTWM running that will keep the server running. Otherwise, if you log off the unix session, the server will end.
Then just substitute the new server name in your line command. The difference between the in-process server and a standalone server is that the in-process server will not always stay active - it will start when it receives a request. The standalone server will stay active all the time and wait for requests.
If the standalone server works for you, I would suggest then putting it in the correct config files to let Enterprise Manager manage it for you. If you get that far, let me know and I can tell you how to do that also. (Plus the instructions are in the Publishing Reports To The Web manual).

How to pass Unix environment variable to a SQL procedure or SQL * Plus

Can any body suggest me how to ,
How to pass Unix environment variable to a SQL procedure or SQL * Plus file..
I am trying to invoke a SQL Procedure from Unix
by passing the value of a Unix environment variable.
Is it possible..?
Thanks in advance.

Srinivas Jaltaru

Within your shell script you can use what is known as a "here document" which is basically a way of wrapping a call to Oracle. The following call to Oracle loops and writes rows to files with numerically increasing file names. Two unix shell variables are used, one in a select statement and one in a spool command :
<pre>
#!/bin/bash
export ORACLE_SID=DEV05
FILENO=1007351
while [ ${FILENO} -le 1008400 ]
do
FILENAME=farm_${FILENO}.txt
DUMMY=`sqlplus -s user20/user20 <<SQLSTOP
set lines 73
set pages 0
set head off
set termout off
set echo off
set feedback off
select rpad(searchx, 8)
from blastx@PRODUCTION
where searchx = ${FILENO} ### here's a shell variable
spool /export/home/user20/sql/psiblast/BACKUP2_D/${FILENAME} ### here's a shell variable
spool off
SQLSTOP`
FILENO=`expr ${FILENO} + 1`
done
exit 0
</pre>

Fetching UNIX environment variables

Does anyone know of a way to fetch a UNIX environment variable into a PL/SQL variable?
Thanks
Kerri

Hi Dave
If you are just running through the conc manager as a regular report you can not do this. At the CM layer publisher is not aware of nor can it be passed environment variables.
If you are on 11.5 why not store the sub template in the template manager and then use our URI to reference it:
xdo://APPCODE.TEMPLCODE.LANG.TERR
Check the user guide.

OMB PLUS - Problem passing Unix environment variables to OMBPlus

Due to a requirement to encapsulate deployment of OWB applications, we currently start OMBPlus.sh from our own wrapper ksh script (deploy.ksh) in order to get the new / changed application into the target control center etc.
We now have a new requirement that means we need to pass the content of the Unix environment across to OMBPlus.sh (and from thence into our deployment tcl scripts).
No problem, if you believe the tcl documentation. The entire Unix environement gets dumped into a hash array called 'env', so you can get the variable's value out just by saying $env(unix_valraible).
Sounds great, it should work a treat.
Except OMBPlus only silghtly resembles tclsh.
The 'env' that gets into OMBPlus bears practically no resemblance to the 'env' that existed before OMBPlus.sh got invoked.
Does anyone have:
a decent explanation for why the env gets scrambled (and how to avoid it) ?
or an alternative method of getting the Unix environment varaible values into OMBPlus ?
Please do not propose passing them all on the command line because (would you beleive it) the values are database passwords !
Edited by: user10466244 on 23.10.2008 09:28

Unfortunately, the java implementation of TCL that Oracle used as the basis for OMB+ is NOT a fully-featured implementation. Just try using packages...
However, and understanding why you don't want to hard-code passwords into a file, you can always edit the setowbenv.sh file in your owb/bin/unix directory to grab your specific shell environment variables and propogate them to the java session.
towards the bottom of this env file you will see a section that looks something like:
JDK_HOME=../../../jdk
OWB_HOME=/owb
ORA_HOME=/owb
OEM_HOME=/owb
IAS_HOME=/owb
ORACLE_HOME=/owb
CLASSPATH=Personalties.jar:../admin:$MIMB_JAR:
CLASSPATH_LAUNCHER="-classpath ../admin:../admin/launcher.jar:$CLASSPATH: -DOWB_HOME=$OWB_HOME -DJDK_HOME=$JDK_HOME -DORA_HOME=$ORA_HOME -DOEM_HOME=$OEM_HOME -DIAS_HOME=$IAS_HOME -Doracle.net.tns_admin=$ORA_HOME/network/admin Launcher ../admin/owb.classpath"
export ORA_HOME
export OWB_HOME
export JDK_HOME
export OEM_HOME
export IAS_HOME
export ORACLE_HOME
You could add in the environment variables that you want propogated, include them into the CLASSPATH_LAUNCHER, and then they will turn up in your OMB+ session env array.
e.g., to propgate an environment variable called MY_DATABASE_PASSWORD you would:
JDK_HOME=../../../jdk
OWB_HOME=/owb
ORA_HOME=/owb
OEM_HOME=/owb
IAS_HOME=/owb
ORACLE_HOME=/owb
CLASSPATH=Personalties.jar:../admin:$MIMB_JAR:
CLASSPATH_LAUNCHER="-classpath ../admin:../admin/launcher.jar:$CLASSPATH: -DOWB_HOME=$OWB_HOME -DMY_DATABASE_PASSWORD=${MY_DATABASE_PASSWORD} -DJDK_HOME=$JDK_HOME -DORA_HOME=$ORA_HOME -DOEM_HOME=$OEM_HOME -DIAS_HOME=$IAS_HOME -Doracle.net.tns_admin=$ORA_HOME/network/admin Launcher ../admin/owb.classpath"
export ORA_HOME
export OWB_HOME
export JDK_HOME
export OEM_HOME
export IAS_HOME
export ORACLE_HOME
So now you have no protected data hardcoded, it will pick up your specific environment variables at runtime, and when you start OMB+ you will be able to:
array get env MY_DATABASE_PASSWORD.

Script fails when passing values from pl/sql to unix variable

Script fails when passing values from pl/sql to unix variable
Dear All,
I am Automating STATSPACK reporting by modifying the sprepins.sql script.
Using DBMS_JOB I take the snap of the database and at the end of the day the cron job creates the statspack report and emails it to me.

From the sprepins.sql script
variable bid number;
variable eid number;

How can I execute a Procedure with OUT variable is %ROWTYPE on SQL Prompt

Hi,
I have a procedure with OUT variable is %ROWTYPE
How can I execute the following procedure on SQL prompt.
(without creating anonymous block)
CREATE OR REPLACE PROCEDURE zz_sp_EMP(VEMPNO IN EMP.EMPNO%TYPE,
V_REC IN OUT EMP%ROWTYPE)
AS
BEGIN
SELECT * INTO V_REC FROM EMP WHERE EMPNO = VEMPNO;
END;
Thanks & Regards,
Naresh

as previous posters said: it's not possible to do this without declaring a variable in the anonymous block.
With anonymous block it would look like this (had to change it a bit, since i'm using hr-schema on oracle XE):
declare
l_rec EMPLOYEES%ROWTYPE;
begin
zz_sp_EMP(VEMPNO => 100, V_REC => l_rec);
DBMS_OUTPUT.PUT_LINE ( 'first_name = ' || l_rec.first_name );
DBMS_OUTPUT.PUT_LINE ( 'last_name = ' || l_rec.last_name );
end;
first_name = Steven
last_name = King

Bad query plan for self-referencing CTE view query and variable in WHERE clause. Is there way out or this is SQL Server defect?

Please help. Thank you for your time and expertise.
Prerequisites: sql query needs to be a view. Real view is more than recursion. It computes location path, is used in JOINs and returns this path.
Problem: no matter what I tried, sql server does not produce 'index seek' when using variable but does with literal.
See full reproduction code below.
I expect that query SELECT lcCode FROM dbo.vwLocationCodes l WHERE l.lcID = @lcID will seek UNIQUE index but it does not.
I tried these:
1. Changing UX and/or PK to be CLUSTERED.
2. query OPTION(RECOMPILE)
3. FORCESEEK on view
4. SQL Server 2012/2014
5. Wrap it into function and CROSS APPLY. On large outer number of rows this just dies, no solution
but to no avail. This smells like a bug in SQL Server. I am seeking your confirmation.
I am thinking it is a bug as variable value is high-cardinality, 1, and query is against unique key. This must produce single seek, depending if clustered or nonclustred index is unique
Thanks
Vladimir

Pass a Value to Variable from the unix environment in ODI (ELT)

Hi
i am very new to ODI environment.
i want know how to pass a value to variables in oracle data integrator from unix environment.
Example:
Variable name : Sales
for variable name sales i want to pass the value from unix environment.
Regards,
Raj
Edited by: user11137587 on Aug 19, 2009 6:26 AM

Work Around !
You can execute OS commands using Jython script. Probably you need to flush your enviornment variables value into a file using jython script and then read those value into ODI variable from the file.
BUt may I know why you want to read environment variable vaules in ODI, Dont you think this will make your application less portable

APEX - accepting OUT variable values from PL/SQL Stored Procedure

I have created a page (Form) which is accepting values text fields.
In the Page Processing section under Processing, I am passing the values to a PL/SQL Stored Procedure, which acts like an API. The procedure contains code to validate the entered data and finally insert the data into the base tables. The procedure also contains OUT variables in the parameter that would return status of processing and any error messages.
Now, my question is, how can I make the page accept these OUT variables from the procedure. What I wish to do is, to capture these messages/processing status from the procedure in the page. For example, if there is a error in the data and the procedure is sending this message in the OUT variable, I need this to be displayed on the page as an error message.
Is this possible in APEX?
Regards,
Santhosh Jose

Hi VC,
I just tried putting the string directly instead of the variable. Its still not giving me the expected results.
HOWEVER, I think the reason was because of the EXCEPTION block in my code. I have an EXCEPTION block to handle exceptions. I commented the WHEN OTHERS section and now the error message is coming on the page.
So what I have done now is as follows: At the point at which the error is expected, I am raising a handled exception. And within the exception handling, I am giving RAISE_APPLICATION_ERROR.
WHEN ex_main_error*
THEN*
p_status := 2;*
p_msg := 'ERROR Stage: '||lc_err_stage||' ERROR Message: '||lc_err_msg;*
RAISE_APPLICATION_ERROR (-20001, p_msg);*
This is working now! Which is very good news. Thanks once again for your help!
Regards,
Santhosh Jose

Convert word into html in unix environment

We are in the process of developing a coldfusion web
application which allows the users to upload resumes in word
format. Once the word document is uploaded we need to convert the
word document into html on the fly. We know it can be accomplished
using com object in the windows platform. But ours is a unix
environment. We need some coldfusion coding which can convert the
uploaded word file into html. Please take note coldfusion server
runs on unix platform in our case.

For step 3 call a 3rd party component such as Aspose.Words to
handle converting test.doc to test.html. I'd recommend wrapping
this logic inside a CFC.
For example using Aspose.Words java object appears to be as
easy as the Java code:
Document doc = new Document(getMyDir() + "Document.doc");
doc.save(getMyDir() + "Document.ConvertToHtml Out.html",
SaveFormat.HTML);
Note: I've used the .NET version of Aspose.Words, not the
Java version, but I've been pleased with the product.
Aspose.Words formats supported
http://www.aspose.com/documentation/file-format-components/aspose.words-for-.net-and-java/ com/aspose/words/saveformat.html

Environment variable PATH and Sql*Plus

Hi all,
i have a problem with sqlplus.
It might seem not to be able to read the path environment variable.
I need to launch some sqls without typing their path (to put the path i should modify morre than 300 shell scripts), e.g.: @script.sql.
My shell scripts are invoked by the database using java.
Inside the shell scripts we have commands like "sqlplus -silent <login> @script.sql [parameters]"
So if sqlplus is not able to read the PATH environment variable, the command hangs waiting for something to do without the chance to close it.(it is silent).
I run RDBMS v8.1.7 on compaq tru64 Unix.
Can someone help me??
Thanks in advance.
Marco - Milan, Italy

Where do I set SQL*Plus SQLPATH variable??As every other unix environment variable - either in your profile or in your current shell whatever you like
Is this the PATH where SQL*Plus searches for .sql
files??SQL*Plus searches for your files in your current directory, and then the directories you specify with the SQLPATH environment variable.
SQL*Plus searches this colon-separated list of directories in the order they are listed.

How do I use a UNIX environment variable for the path of a file name

We are running Forms 6i over the web. The forms server runs on a UNIX (HP-UX) machine.
I want to read the contents of a file, which is simple enough, using the TEXT_IO package. However, I want to reference a UNIX environment variable that specifies the file path i.e
PROCEDURE get_file IS
in_file Text_IO.File_Type;
linebuf VARCHAR2(1800);
filename VARCHAR2(200);
BEGIN
filename:= '$LOG_DIR/RCAS181.log';
in_file := Text_IO.Fopen(filename, 'r');
.....other stuff
Notice the filename string references my unix env variable '$LOG_DIR'. However, this doesnt work. If I put the full pathname it works fine.
Any suggestions ?

Have a look at TOOL_ENV.GETVAR()

Can i use a environment variable inside a *.sql file?

Hello,
I want to create a external table.
So i am using the command
create or replace directory abc as 'C:\folder'.... inside a sql file.
Now i want the path "C:\folder" to be dynamic as i am using this path in many other places also inside the sql file.So i thought to create a environment variable and put this value there.I tried using as %PATH% but it gives error..... where %PATH%=C:\folder.
Can i use a environment variable inside a *.sql file?
But how to do that or is there any other way.
Thanks

Actually what i want is the path "C:\folder" is not fixed it can be anything which i may not know the user may decide it later. Not supported. A directory object refers to a specific physical location (directory/folder) on a file system. Not a path.
You can work around it by (creating and) using a function (running under a super user schema with authid definer privs). The caller (e.g. schema scott ) calls it with a physical path. E.g. GetDirectoryObject( 'C:\folder\2010\feb\week4' ).
This function determines if there is an existing directory object for the path. If not, it uses a wildcard search to determine if there are any directory objects for parents in the path (e.g. for C:\folder\2010\feb or C:\folder\2010 or C:\folder ).
If it finds a directory object, it interrogates the data dictionary to determine if the caller, schema scott for example, has read/write access on that directory object. If it has, it creates a new directory object and grants the caller read/write access to it. The function then returns the name of the directory object to the caller.
The caller thus do not deal directly with directory objects. The function returns the object name given a physical path as input. Also, only a single base directory needs to be created (e.g. for C:\folder ) and access granted to the schema on it. Any sub-directory in that base directory can now be dynamically accessed by the schema.
