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.

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()

Java and UNIX environment variables

Hi folks,
am I right when I say that it is not possible to access UNIX environment variables from Java (these ones delared by the export statement)?
Cheers,
Heiko

Yes.. Since some OS do not have the concept of environment variables,it is directly not possible.
But using the method System.getProperties you can get
some inf about the environment.
the following links may be of some help to you

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.

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>

XSL variable and unix environment variable

Any idea how I can pass the unix environment variable to the custom XSL file? I want to be able to pass the $PO_TOP path so the file location can be derived
The below code works fine for static file location but I want it to be more generic.
<fo:block xsl:use-attribute-sets="termcond">
<xsl:if test="($print_draft = '')">
<xsl:value-of select="unparsed-text('/usr/tmp/tc.txt','UTF-8')"/>
</xsl:if>
</fo:block>
<fo:block id="last-page"/>
Thanks in advance

you'll need to use the name(.) XPath function to test the name of the current node.

Changing UNIX environment variables?

Is there an easy way to change the environment from inside Java-code?
I have tried using the compile version and this works fine.
Compile version:
java -DmyVar="$PATH" myClass
and then used System.setProperty("myVar", "/home/lala");
The above works fine and changes the PATH variable in UNIX, but i don�t want to set these things at compiletime, is there another way?
Thank you for any hints
// adde

I want to change the systems environment variable when I run my Java application, what happens when I close the program does not concern me. And I don�t just want to fetch what�s currently there, I want to change them and then use them in my program.
But can you somehow do this without telling the program what variables you are interested in at compile time?
Thank you for your answers

Unix Environment variable for connect string in SQL*Plus

I am using some environment variables to connect to a sql*plus session in unix.
they are exported as part of a file which contains the following and gets executed through the .profile.
export db_username=xxx
export db_password=xxx
export db_name=xxx
i have created a file abc.sql which contains the following
connect $db_username/$db_password@$db_name
Now, I have a shell script which uses this file inside it to connect to a sql*plus session and execute some queries.
The contents of the shell script :
API_CONNECT_SQL=abc.sql
sqlplus /nolog << THEEND
WHENEVER SQLERROR EXIT SQL.SQLCODE ROLLBACK
WHENEVER OSERROR EXIT FAILURE ROLLBACK
set timing on
@${API_CONNECT_SQL}
---- do something
EXIT
THEEND
Now, the sql*plus session is able to get db_username and db_password, but not the db_name. It says "TNS service name not found".
If I hardcode some database name in place of db_name, it connects properly.
Please let me know the problem and solution as well.
Any help appreciated.
thanks,
Vijay

for me this one works
# =========================================
# begin of script
# =========================================
export db_username=alpha
export db_password=bravo
export db_name=charly
echo "connect $db_username/$db_password@$db_name" > xxx.sql
API_CONNECT_SQL=/cfs/dummy1/0/appl/dummy2/rev_04/zzz/tst/xxx.sql
cat ${API_CONNECT_SQL}
sqlplus /nolog << THEEND
spool xxx
WHENEVER SQLERROR EXIT SQL.SQLCODE ROLLBACK
WHENEVER OSERROR EXIT FAILURE ROLLBACK
set echo on
host cat ${API_CONNECT_SQL}
@${API_CONNECT_SQL}
select * from dual;
spool off
EXIT
THEEND
# =========================================
# end of script
# =========================================

Getting a Unix environment variable

Hi, everyone.
I need to use a Unix enviroment variable from a form. This form
is gonna use this variable in order to be the path of another
form who is gonna be called.
In other words:
CALL_FORM( $unix_var + '/forms/myform_name' );
unix_var is what I want to get.
Thanks a lot in advance,
Eduardo

It worked, Michael. Thanks a lot!
To the documentation guys at Oracle... This is how you define
the TOOL_ENV package in the Forms' help:
"The TOOL_ENV package allows you to interact with Oracle
environment variables by retrieving their values for use in
subprograms."
Suggestion: ...with Oracle environment variables AND OTHER
SYSTEM OPERATION ENVIRONMENT VARIABLES...
because this narrow definition can prevent people for trying to
use it to retrieve other NON-ORACLE environment variable via
this package. Thanks.

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.
cheers,
Mike

Unix Environment Variables

I use EBS 11.5 and I am trying to use XML Publisher with RTF files for PO printing. I have a main script loaded into Oracle as the template and it uses
<?import:file///home/dave/scripts/test.rtf?> to pull in a subtemplate. I want to change this to reference an environment variable, like MY_HOME, instead of having the directory hardcoded into the import statement.
Home do I do that?
What is the syntax in the import statement?

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.

Unable to access value in System Environment Variable using Java

I am using Java code to get the value of a System Environment Variable using the Runtime, Process java classes.
The code works fine in tomcat, but when deployed in 9ias the code is unable to retrieve the value stored in the System environment variable in Windows 2000.

Thanks for the comment steve, here is the code which i am using.

Hi,
Have you referred these following SAP Notes ? All the required Environmental Variables related to Oracle are well described there.

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.

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

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.
