Perl in oracle home

i am using unix env and i need per ver 3 inorder to upgrade oracle from 9.2.0.4 to 9.2.0.7. some how it's reading per ver 2 from my unix env. question is there also anywhere else in oracle home that i need to look in other word how i can tell that oracle looking the perl in the oracle home or out side the home.
Thanks

Not sure exactly what you mean,
in unix box,
type
which perlwill show you which perl program system will choose to run without absolute path
of course if there's any perl under current path setting
If you want to run perl version under ORACLE_HOME as default, put this line first in your path
$ORACLE_HOME/Apache/perl/bin
in C shell it's like this
set path = ($ORACLE_HOME/bin /usr/sbin $path)

Query regarding perl in Oracle Home

Hi All,
One of my customers has asked the following question
There is Perl 5.6.1 present in OracleHome but I can't use it like Perl is meant to be, because there is no makemaker ... so I can't use modules provided by CPAN. I want to know if it is possible to use this Perl? What is the Oracle-Recommended-Way to use CPAN-Modules? That is I want to know how can I compile any perl module from CPAN with the perl present in Oracle Home
Thanks and Regards,
Geeta

Using perl with Oracle DB

Hi,
I have perl scripts to import csv data to an existing 9.2 oracle database 32bit. It is using DBI to connect. I am moving the database in question to 10gR2 windows X64. I want the scripts to follow and run on the new server.
I know there is an install of perl in the oracle home. Is it intended to be used by oracle internally only?
So my question is: should I install perl separately or could I use the one shipped with oracle?
Best wishes!

Of course.
You are right if more modules are required, then adding them to the oracle perl would have potentially bad effects.
The only thing I need really is to read files, call sqlloader, connect to the DB and run some stored procedures... I will be ok then. I already tested connectivity and it all looks fine.
Thank you very much for the input!

Java/JDBC slow compared to Perl/DBD-Oracle

Hopefully the subject is inflammatory enough to get some responses :-)
I'm thinking about converting a database-intensive Perl application to Java, but it's fairly database intensive. Things look pretty straightforward, but Oracle's OCI JDBC driver seems to run at about 2/3 the speed of Perl with the DBD-Oracle driver.
For comparison, here's the Java version:
=== SelectTest.java
import java.sql.*;
import oracle.jdbc.driver.*;
public class SelectTest {
public static void main(String args[]) throws Exception {
int count = Integer.parseInt(args[0]);
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection conn = DriverManager.getConnection(
"jdbc:oracle:oci8:@orcl.world",
"scott", "tiger");
String statement = "select * from dual";
OraclePreparedStatement stmt =
(OraclePreparedStatement) conn.prepareStatement(statement);
stmt.defineColumnType(1, Types.VARCHAR);
stmt.setRowPrefetch(1);
for (int i = 0; i < count; i++) {
ResultSet rset = stmt.executeQuery();
rset.next();
String s = rset.getString(1);
rset.close();
stmt.close();
=== End of SelectTest.java
and here's the Perl version:
=== select_test.pl
#!/usr/bin/perl -w
use strict;
use DBI;
my $dbh = DBI->connect('dbi:Oracle:dev.cag', 'cag', 'gac');
my $sth = $dbh->prepare('select * from dual');
for (1 .. $ARGV[0]) {
$sth->execute;
my @data = $sth->fetchrow;
$sth->finish;
=== End of select_test.pl
On my Linux box at home, 'time java SelectTest 1' gives me:
1.120u 0.140s 0:01.35 93.3% 0+0k 0+0io 4334pf+0w
and 'time java SelectTest 1000' gives me:
2.290u 0.370s 0:03.87 68.7% 0+0k 0+0io 4334pf+0w
So the OCI driver can execute about 400 execute/next's per second.
In comparison, 'time select_test.pl 1' gives:
0.550u 0.070s 0:00.74 83.7% 0+0k 0+0io 1638pf+0w
and 'time select_test.pl 1000' gives:
1.210u 0.220s 0:02.41 59.3% 0+0k 0+0io 1638pf+0w
So the Perl/DBD-Oracle runs at about 600 execute/fetch's per second.
The results are similar on our Sun 3500.
I'm at a loss to explain this. I'm explicitly setting the prefetch, using the Oracle defineColumnType extension, and preparing the statement outside the loop. Amazingly, the Perl program beats it with practically no optimization.
This is actually a best-case scenario for the JDBC driver. In the worst-case scenario, the same program running against a table with 50 columns runs about 6 times faster with Perl/DBD than with Java/JDBC. (Large records seem to be a particularly bad case for the JDBC driver).
These tests are actually highly important for our application, which frequently issues single-row selects.
I'm desperate to increase the JDBC performance. Every other test I've run shows Java running several times faster than Perl. Once I can get this ironed out, we should be all set.
For the record, the tests were run using JDK1.2 against classes111.zip. The results were similar using classes12.zip.
Does anyone have any suggestions? I'm hoping there's something obvious I'm missing that will speed up my code to acceptable levels.

ddankwerth,
Actually, we're using persistent connections with mod_perl, so I'm not anticipating a big speed boost there.
Do you have a code example where the thin driver outperforms the OCI driver? In my tests, it's at least 30% slower.
One thing I noticed after posting my question was that the total idle time for the JDBC code was about 50% higher than for the Perl code. This makes me think that the JDBC driver is making more calls to the DBMS than necessary.
Is Oracle actively tuning the JDBC drivers? I get the impression from the classes12 README that the development is focusing more on keeping up with the JDBC standard than with performance.
Does anyone know if there any plans to improve performance?

Need of Two Oracle Home in R12

I am a newbie apps dba and was going through the oracle documentation. Where I learnt that in r12 there are two ORACLE_HOME 10.2.0 and 10.3.0. I tried to research regarding the same but couldn't find anything conclusive enough that would clear my fundamentals regarding the need for having 2 ORACLE_HOME. Of what I have understood , 10.2.0 is Developer Home which hosts the Apache, forms server etc and 10.3.0 hosts the JAVA/html server etc. Is my understanding correct regarding the same ? and what is the use and advantage of having two Oracle Homes? Do explain me in laymen terms as I am still a newbie!

BhaviSavla;
I guess you dint understand what I have said!!! I HAVE ALREADY READ THAT THOUSAND TIMES!!! Please think double&triple time while you are talking wiht Hussein Sawwan about EBS related questions. I am sure about Hussein Sawwan understand your question as he understand other questions and already he has been answered your question(If you have ability to understand what you read)
I strongly suggest you about TO BE KIND-RESPECT with forum users which are trying to help other people here.
And I am still not able to understand the actual advantage of having TWO ORACLE_HOME...After read something, If you still understand than dont blame forum users. Choose easy way... Rise SR!
Kindly do not post just to increase your number of posts on this forum!! If you cannot help me in anyway with this, kindly do not post!If you dont follow OTN forum site consistently than DO NOT MAKE COMMENT about people here If the topic is Hussein Sawwan.
I must remind you something... He has more than 50k post wiht 51k points which mean he made post here like your_post_count*1500times... Wiht other words, his each post equal to 1 point, which mean his each post has meaning which are helpful!
Do you have capability to calculate how mch time he spend here?
Dont thing so!

Multiple oracle home installation

I am going to install oracle 11g2 on hpux server. The server already has 10g on it and the plan is to run both for sometimes.
Unfortunately, IUnfortunately, I don’t have prior experience installing multi-homed oracle software and I
need help on how to supply the oracle home directory name to the installer:
Do I have to supply the installation (OUI) with the oracle home directory: i.e
Exiting oracle home: /u00/app/oracle/product/10.2.0/db_1
For the new oracle home: /u00/app/oracle/product/11.2.0/db_2
Is this correct?
thank you,
Lou

What I did was create two profiles. My OS is similar, but NOT the same
My default is Oracle 11.
However I need a way to go back between Oracle Homes so I created an "o10g.profile" and a "o11g.profile"
o10g.profile
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR
export ORACLE_BASE=/u01/app/oracle
unset ORACLE_HOME
export ORACLE_HOME=/u01/app/oracle/product/10.2.0
#export DISPLAY=localhost:0.0
export TZ=CST6CDT
export ORA_OCI_NO_OPTIMIZED_FETCH=1
ORA_OCI_NO_OPTIMIZED_FETCH=1; export ORA_OCI_NO_OPTIMIZED_FETCH
export ORACLE_SID=STANDBY
export ORACLE_TERM=xterm
#export TNS_ADMIN= Set if sqlnet.ora, tnsnames.ora, etc. are not in $ORACLE_HOME/network/admin
export NLS_LANG=AMERICAN;
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
export LD_LIBRARY_PATH
# Set shell search paths
unset PATH
PATH=/usr/sbin:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin; export PATH
export PATH=$PATH:$ORACLE_HOME/bin
#CLASSPATH
CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
CLASSPATH=$CLASSPATH:$ORACLE_HOME/network/jlibNotice the unset ORACLE_HOME at the top, this is key. Also the unset PATH.
Now compare it to my o11g.profile file
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR
export ORACLE_BASE=/u01/app/oracle
unset ORACLE_HOME
export ORACLE_HOME=/u01/app/oracle/product/11.2.0
#export DISPLAY=localhost:0.0
export TZ=CST6CDT
export ORA_OCI_NO_OPTIMIZED_FETCH=1
ORA_OCI_NO_OPTIMIZED_FETCH=1; export ORA_OCI_NO_OPTIMIZED_FETCH
export ORACLE_SID=PRIMARY
export ORACLE_TERM=xterm
#export TNS_ADMIN= Set if sqlnet.ora, tnsnames.ora, etc. are not in $ORACLE_HOME/network/admin
export NLS_LANG=AMERICAN;
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
export LD_LIBRARY_PATH
# Set shell search paths
unset PATH
PATH=/usr/sbin:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin; export PATH
export PATH=$PATH:$ORACLE_HOME/bin
#CLASSPATH
CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
CLASSPATH=$CLASSPATH:$ORACLE_HOME/network/jlibIts probably a great idea to review the document Srini refers to. However this is a short and sweet example. In my case I can issue a
source o10g.profileAnd be on Oracle 10. So to install the other version I created the profile for it and then then used it to switch to that ENV for the install.

Multiple Oracle home

Hi ,
I have some doubt which needs to be cleared.
If I will install multiple oracle home like ORACLE_HOME=/u01/app/oracle/product/10.1.0/asm
ORACLE_HOME=/u01/app/oracle/product/9.2.0
ORACLE_HOME=/u01/app/oracle/product/10.2.0
ORACLE_HOME=/u01/app/oracle/product/crs
Now in this when I will set export ORACLE_HOME then which version will be picked up.
Is ORAENV isgoing to come into picture.
Please throw some light on it.

Asif KabirAsif,
Your advice to hard code the Oracle environment directly into the profile is poorly thought out. And a direct carry over of 'worst practices' unfortunately taught in some Oracle related classes.
The OP did correctly identify oraenv (as described in the "Administrator's Reference for UNIX-Based Operating Systems" at http://www.oracle.com/pls/db102/portal.portal_db?selected=4) as the preferred solution. Putting THAT into the profile (using ORAENV_ASK as described in the manual) is OK.
I'll leave you to figure out why the difference - I've posted many times about that in these forums.

CRS install fails Oracle home incompatibility checks ( 10G )

Hi,
I'm trying to install RAC for 10.2.0 . The first step is to install cluster Ready Services ( On red hat linux ) . When it does the product specific prequisite checks, it fails on "Checking for Oracle home incompatibilities".
I get the error " Oracle clusterware cannot be installed into an existing oracle home".
I did a previous attempt at an install which failed. I have completely deleted the
/oracle/product/10.2.0/crs directory which was previously created.
If I check the environment variables, I get :
[oracle@rac1 db_1]$ env | grep -i home
HOME=/oracle
ORACLE_HOME=/oracle/product/10.2.0/db_1
So, in my thinking there is no trace now of a previous home for CRS.
So why am I getting the error ??
Thanks
George

It seems taht you have not cleared the inventory..As menioned earlier use OUI to remove the oracle_home from inventory. In case you do not wish to use the existing ORACLE_HOME=/oracle/product/10.2.0/db_1 or any other Oracle Installation on this server, then you can go ahead and remove the inventory itself.
You can use Note:239998.1 for the various files to be removed for cleaning up CRS..

Multiple APEX instances sharing the same Oracle Home?

Can someone tell me if it is possible to have multiple APEX installations where the database instances are sharing the same Oracle Home? If so, how would this be set up?
So, if I have development and test running on the same home, I want a separate APEX instance for each. We can do this when different Oracle homes are used (separate httpd running) but not for the same home.
Thanks

Thanks - We have tried putting 2 dad entries in file, but not sure how you connect. You only specify a port number, so how does it connect that to a db???

These questions show a certain lack of knowledge about Oracle - which immediately says that you also do not know what you are doing ito performance and scalability of a Oracle and that server platform by running multiple instances on it.
In most case, running multiple instances is the wrong thing to do. It degrades performance. It does not and cannot scale. It is an exception to the basic fundamentals of client-server. And not just for Oracle.
You need sound technical justification for running multiple instances on a server. What is yours?

Forms installation problem - how do I create a new default Oracle home?

I am new to Oracle so please forgive my utter ignorance. My impression of Oracle because of how an installation
has to be done is taking a nosedive. I thought Microsoft was bad with all the re-booting but the explanation that I
read in Anubhav Seth's post about installing Dev 6i before 8i and the suggestion (not a requirement) to format the
harddisk and reinstall Windows just leaves me with my jaw hanging open. I'm having a little trouble swallowing that
one.
Here's my situation... I'm running 8i at home and I am using it for the Oracle courses that I am taking at a local
university. So 8i with its SQL*Plus has been all I have needed to date. Now we have a project to do that involves forms.
So I go to the OTN page for downloads and downloaded file 6irel2nt.exe which is 264 MB in size. This file, I assume,
has forms in it -- what else I don't know because things are not explained all that well on the web site or I don't know
where to look (which implies poor organization of the web pages).
I run the 6irel2nt.exe file and end up with 11,128 new files on my computer. That's nice. I run the setup file and a step or
two into it it complains that my 'Ora81' home is already being used and that I need to install it into another Oracle Home.
Now I'm trying to find out how I create another Oracle Home. I perform a search in GOOGLE on "creat default Oracle
home" and basically get nowhere. My $50+ "Oracle 8i A Beginner's Guide" from Oracle Press mentions Oracle Home
on one page (pg. 170) but is completely useless in this case. My $184 worth of Oracle University manuals (which
are really PowerPoint slides) is useless too. My next step will be to comb through the FAQs. All this because I cannot
believe that I have to totally uninstall one product to get another to install and then reinstall the first one. That is INSANE!
If I have gone way off track please feel free to blast me but if this is true then all I can say is that the folks at Oracle need
a lesson in KISS (Keep It Simple Stupid)! Computers and computer software are supposed to make our lives simpler
not complicate the holy hell out of them. I'll get off my soapbox now. Sorry about the whining.

I ended up uninstalling 8i and then I installed Dev 6i (Forms) and then I reinstalled 8i. I had some problems
installing Dev 6i because of this error "path.vrf(86): Unbound variable 'path_too_long_prompt'". Right after this error
appears I get a dialog that states, "The Oracle Installer cannot update the system path variable to %new_path%
because it is too long. Please restrict your system path to 127 characters and make sure D:\Oracle\OraWin95\bin
is included in your path."
The path D:\Oracle\OraWin95 was what I set up for this installation.
What I did to work around this problem was this...
(1) Go to Start - Accessories - System Tools - System Information.
(2) Click on the Tools menu
(3) Select System Configuration Utility
(4) Select the Autoexec.bat tab
(5) I added D:\Oracle\OraWin95\bin to my PATH variable and unchecked the checkbox next to one of the several
lines that I have that build my PATH variable. (I have several PATH lines that simply add a path to the system
variable %path%). After the installation is complete you can go back and turn back on the paths that you had disabled.
After installing 8i I did have a problem connecting to the database. I got this error:
Error: ORA-01034 Oracle not available
I believe this happened because I had forgotten to turn back on some of my PATH information that I mentioned
earlier. After checking one of my PATH variables and rebooting, this problem disappeared.
When reinstalling 8i and when the installation asks for an SID and you enter the SID you had used in the original
installation you may get a notice that says the SID already exists. I think this happens because the uninstall does not
clean up the registry totally, so I entered a different one. Later on, after the installation has been completed and you
are connecting to your database, you will be prompted to select an SID -- just make sure that you select the SID from
the latest installation.
I should've mentioned first that in preparing for this whole ridiculous exercise I created a directory under my Oracle
directory that I was going to use as the new 'Oracle home.' So I guess that's all one has to do to create a new Oracle
home -- just have another directory ready to install 'stuff' into.
All in all, this a pretty asinine exercise. Oracle really needs to fix this mess. I honestly thought Microsoft was bad but
this takes the cake. I wonder if SQL Server is this screwed up.

Creating a new database in a new Oracle home

Hi,
I'd like to add a new database using dbca, but I want it in a different Oracle Home to the other databases on the server. I notice that in the dbca I do not get an option to specify a new Oracle home. I assume it is because this tool is only for database creation and not instance creation. Do I therefore need to do a full Oracle install in order to create a second Oracle home?
Many thanks.
****Ignore this, I know what I'm doing now****
Edited by: user11201026 on Aug 6, 2009 3:52 AM

You need to better understand what an ORACLE_HOME is. An Oracle home has nothing to do with a Oracle database.
ORACLE_HOME defines the location of an installation of an Oracle software installation.
Where you decide to put a database is irrelevant to the location of an ORACLE_HOME.
One ORACLE_HOME can have zero, one, or many databases.
But you can not have an ORACLE_HOME without an installation of Oracle software.
The concept docs are at http://tahiti.oracle.com.

Error while appying patch set 4 (10.1.3.4.0) to oracle home (10.1.3.1.0 )

Hi,
I am trying to apply patch set 10g Release 3 (10.1.3) Patch Set 4 (10.1.3.4.0) to 10g Release 3 (10.1.3.1.0) oracle home. As the pre - installation steps describes I have run the script ‘upgrade_10131_10134_oracle.sql’ for both ESB and BPEL. Also we need to delete the line <data id="java-bin" value="/myhost/jdk1.4.2/bin/java" />from the ‘ORACLE_HOME/opmn/conf/opmn.xml’ file. But when I have checked that file, the line was not present there.
But when I am running the installer, it is showing error like
Error

failed to start a managed process after the maximum retry limit
Log:

Does anybody know how to fix this problem?
Thanks & Regards,

There is a quick fix for this
There are 2 lines you need to comment form the c:/oracle/soa_ofmpractice/soatesting/apache/apache/conf/httpd.conf
A comment is done with a #
If you look in the C:\Oracle\Soa_OFMPractice\SOATESTING\opmn\logs\HTTP_Server~1.log file it will tell you.
Find the line that has apachemoduleossl in it. When you try and restart it will fail again the C:\Oracle\Soa_OFMPractice\SOATESTING\opmn\logs\HTTP_Server~1.log should tell you what line to comment
sorry can't be of much more help but dont have access to an environement at the moment.
