Oracle instant Client and memory

Hello everybody,
I have just installed the Oracle Instant Client on my Linux server (Redhat distibution), I recompiled PHP (4.4.2 version) with the oci8 extensions and I reboot Apache (1.3.34 version)...
In short, the installation of OIC goes perfectly (No error messages...), and I can request a remote Oracle server from a PHP file. (All this, for one PHP script that I use only once a day, to load data in a MySQL table).
However, since I installed the OIC, my Apache processes exceeds the 200 MB and my server has a commit memory more than 2GB (sometimes it goes until 5GB).
Is it a problem that can come from the OIC ? Maybe, a parameter could fix that problem ?
Thx in advance.
Maat

If you can't upgrade from PHP4, you should upgrade at least the OCI8
extension. All PHP 4 releases have a very, very old version of OCI8.
Steps to upgrade are given in the free Underground PHP and Oracle Manual
The Instant Client Basic package uses a chunk of (shareable) memory
for all its NLS data. The Instant Client Lite package uses a smaller
footprint.
Make sure you know what you are measuring and whether what you are
seeing actually has an effect on performance.

Oracle Instant Client and OUT Parameter of custom type in Stored Procedures

Hi @ all!
I try to set up a simple client application, that calls a stored procedure via Instant Client from C#.
The stored procedure and assiciated types looks like this:
TYPE MYVALUE AS OBJECT
      Id      INTEGER,
      value     FLOAT
TYPE MYVALUELIST AS TABLE OF MYVALUE;
PROCEDURE ReadValues( ID IN INTEGER,
                                    RESULTSET OUT MYVALUELIST)
                                       IS
...I created an Oracle Command executing this SP and added OracleParameters for ID and (where I got stuck) the RESULTSET.
Is it possible to pass a parameter with a custom type from C# in some way?
I already tried it as a function with SELECT * FROM TABLE(ReadValues(1));
With my parameter RESULTSET as the RETURN type. But since I use DML within the procedure, this does not work inside of a query...
Any suggestions?
Thanks in advance!

Hi Greg!
Sorry, I misunderstood the forum topic then. =(
Anyway, in the example you provided in the link, this is nearly exactly my situation. But there the Oracle.DataAccess.Client is used, where the OracleDBType can be called to initialize an object of type person. I use the instant client libraries called by using System.Data.OracleClient. There is only the OracleType enum, that does not contain an object or something similar.
So I do it right now after trying a bit with a ref cursor parameter and an OracleDataAdapter - the ref cursor is passed back from Oracle as a DataReader, so die DataAdapter is able to use it for a .Fill():
OracleCommand cmd = new OracleCommand();
cmd.Parameters.Add("RESULTSET", OracleType.Cursor).Direction = ParameterDirection.Output;
OracleDataAdapter odr = new OracleDataAdapter(cmd);
DataTable result = new DataTable();
odr.Fill(result);Within my stored procedure I just added the following OUT parameter:
PROCEDURE ReadValues( ID IN INTEGER,
                                    RESULTSET OUT sys_refcursor)
                                       IS
currentlist MYVALUELIST;
... [Adding elements to that list] ...
OPEN resultset for select * from TABLE(currentlist);It works now, but I don't like that solution that much since I'm always afraid that there are lots of opened cursors idyling around. Do I have to close this one explicitly after filling my table by the DataAdapter?
Regards

Apologies - thought it was a database to database connection that you were trying to create.
isql: error while loading shared libraries: libreadline.so.3: cannot open shared object file: No such file or directoryThe readline library is in package readline-4.3-13 on RHEL4 and in readline-5.1-1.1 for RHEL5 on my servers (minor version number are of course dependent on the kernel version used).
This is also not an ODBC or Oracle issue. It seems that isql is using rlwrap or similar - this requires the readline library. And possibly LD_LIBRARY_PATH to be set too.

I don't understand your step 7 (the first step 7, actually).
What is that unixODBC-2.2.14-linux-x86-32.tar.gz, where did it come from, and why are you doing all that?
unixODBC should be installed after step 5.
I guess that that is the cause of your problem.
isql is not linked against readline at all on my RHEL 5 system.
Do you notice any improvement after removing the files from that tar.bz file?
Yours,
Laurenz Albe

Solaris PHP 5.2.12 Oracle Instant Client Error

We are testing a Oracle Solaris Express 11 Server with the standard Apache and PHP installation. But we need the Oracle Instant client and the oci8 module enabled for our company applications.
We did this by using ./pecl install oci8 in /usr/php/5.2/bin. We set the LD_LIBRARY_PATH in /etc/apache2/2.2/envvars
a 32bits solaris (x86) version of the Oracle Instant Client 11.2 is installed in /opt/oracle/instantclient_11_2 with the symbolic link made.
envvars:
LD_LIBRARY_PATH=/opt/oracle/instantclient_11_2
ORACLE_HOME=/opt/oracle/instantclient_11_2
ORACLE_BASE=/opt/oracle/instantclient_11_2
he oci8 module installed and php loads it.
phpinfo(); output:
oci8
OCI8 Support enabled
Version 1.4.6
Revision $Revision: 313688 $
Active Persistent Connections 0
Active Connections 0
Oracle Run-time Client Library Version 11.2.0.2.0
Oracle Instant Client Version 11.2
Temporary Lob support enabled
When we first view a site there is no problem but very randomly we get the following error:
OCIEnvNlsCreate() failed. There is something wrong with your system - please check that LD_LIBRARY_PATH includes the directory with Oracle Instant Client libraries*
but when we use echo getenv("LD_LIBRARY_PATH"); in php the output is "/opt/oracle/instantclient_11_2"
now the strange this is as randomly as it appears it disappears we can load the web-page without problems and after a couple of clicks the error is back. if we wait a coupe of seconds you can reload the page and it loads normaly.
The error appears to be random and we get it over and over agian, it comes and goes after a cpl of pages are viewed. It seems to appear more when there are multiple users browsing on the website.
Is there a fix for this? is this an known bug? It seems strange the instant client works some times and fails a second later without a change in the system.
Hope someone can help us.

Solved it by compiling apache 2.2.20 into 64bits using:
CFLAGS="-m64" CXXFLAGS="-m64" LDFLAGS="-m64" ./configure enable-so enable-cgi enable-info enable-rewrite enable-deflate enable-ssl
and compiling php 5.3.8 into 64bits:
CFLAGS="-m64" CXXFLAGS="-m64" LDFLAGS="-m64" ./configure with-apxs2=/usr/local/apache2/bin/apxs with-gd with-zlib disable-ipv6 with-jpeg-dir=/usr/ with-png-dir=/usr/ with-freetype-dir=/usr/ with-pear with-openssl with-oci8=instantclient,/opt/oracle/instantclient_10_2
and using the 10.2.0.4 instant client.
there might be a bug in the 11.x ones, they dont seem to work on Oracle Solaris 11.

Error Compiling php 5.1.6 with Oracle Instant Client 10.1.0.5 on Fedora 5

Hello
I have Oracle 10.1.0 enterprise database installed on a Windows 2003 server.
I have another machine that has Fedora Core 5 installed on it. I downloaded:
Apache 2.2.3
Php 5.1.6
OracleInstantClient 10.1.0.5 (base and skdk packages) from technet.oracle.com
I created a directory called /usr/lib/instantclient10_1 in which I unzipped
the files for the Oracle Instant Client and the SDK into /usr/lib/instantclient10_1.
So inside /usr/lib/instantclient10_1 I have:
all the unzipped filed from the base for the instant client as well as
a directory called sdk with files inside this subdirectory.
I compiled and installed Apache.
I then tried to configure php using the instantclient with the configure option
--with-oci8=instantclient/usr/lib/instantclient10_1
The first time I did this I got the error: "link from
/usr/lib/instantclient10_1/libclntsh.so to libclntsh.so.10
not found"
Well I had the libclntsh.so.10 but no such link. So I did the following:
ln -s libclntsh.so.10.1 libclntsh.so
I assume this was OK to do but I found it strange that I had to do this.
Question #1 - why should I have to do this?
I then tried to configure php again but got an error that I paste in from
the debug.log. From this debug log you can see the configure options I gave for
php as well as the error. It says "cannot find -lirc". Now I did put into
/etc/ld.so.conf the line /usr/lib/gaim since that is where libirc.so is and ran
ldconfig but it still complained. When I copied libirc.so into /usr/lib it then said there were
lots of errors in that libirc.so. The only item in the configure options depending on lirc is
the with-oci8. Why does with-oci8 depend on lirc?
I also tried the above on Red Hat AS 4.0 and got the same errors.
Question #2 -- what do I do?
Thank You
Gail Lange
Here is the debug.log in the case when libirc.so is just in /usr/lib/gaim:
CONFIGURE: './configure' '--with-apxs2=/usr/local/apache2/bin/apxs' '--enable-track-vars'
'--enable-inline-optimization' '--with-gd' '--with-zlib' '--enable-debug'

To be perfectly honest, I'm not sure. Everything I could find on it had to do with IRC or some kind of remote control thing (for controlling audio/media players). Maybe if Ivan stops by he'll know what it means... he knows quite a lot about the inner workings of many of these libraries.
http://us3.php.net/install.unix was the most useful info I could find.

Request: enable use of sql*plus via Oracle Instant Client.

hi,
great project....
I've just installed Raptor release 3 on top of oracle instant client, and it seems to be running fine. my sql*plus from the instant client functions from the command line, but the sql*plus menu item in the tools menu is grayed out.
review of the help files say's that oracle_home must be set, but instant client does not need an oracle_home. (uses tns_admin instead).
is there a work around for this? (other than loading the full oracle client w/ it's sql*plus)
thanks
GT

The SQL*Plus menu item does not seem to be correctly detecting the current connection context. I'm filing this as a bug to be fixed before we ship. In the current version, however, you can enable the menu item by ensuring first that the connection is selected in the Connections navigator.
When the menu is invoked, you will be prompted for the location of the SQL*Plus executable. On Windows, this should just be the path to sqlplus.exe (or sqlplusw.exe). On Unix platforms, you should include 'xterm' or an equivalent in order to ensure that SQL*Plus invokes in a window.

Oracle Instant Client is a memory hog?

Hi all,
I am having (potentially) an issue that I need to confirm with folks out there. I am not a DBA - I have a decent understanding of SQL and have been exposed to several RDBMS's, but this is my first time developing in PHP specifically with Oracle in mind.
First, my setup (note this is for development, not production; ultimately, the final deployed environment will be 2 high-end SPARC servers (one for web, one for db)):
1. DEV: Webserver running Solaris 10, Apache 2.0.52 and PHP 5.1.2 and Oracle Instant Client v.10.1.0.3 (note all versions except PHP haven been dictated by the customer). PHP is compiled with apxs2, postgres, sqlite-utf8 and oracle support (hooked into instant client).
2. DEV: DB server running Oracle 10g on Windows 2003. Using stock configuration.
I have a PHP application using AdoDB for abstraction and Smarty for templating; also using Fusebox.
The whole setup as described above works flawlessly. I notice that the apache process(es) usually sit between 20-25M given the LoadModule configuration in Apache, and the extensions being loaded in PHP. Whenever I make connection to postgres, or sqlite, the processes stay within the described memory usage patterns above (so 20-25M).
However, whenever I attempt making a connection using the Oracle Instant Client (using either native OCI8 or adoDB calls, using both persistent and non-persistent connections), the Apache process jumps from a meager 20-25M to 85M+... I don't even have to do a select - just the very action of establishing the connection results in this jump in memory usage.
What I need to know is - is this normal? Is it normal for the client to have this size of a footprint on memory? If so, I need to ensure that the final deployed environment is capable of handling these kinds of jumps. If this is NOT normal, well, heck folks, I need some friendly pointers.
Any and all help would be greatly appreciated.
Thanks,

I emailed the OCI team and got this:
'Basically, the data shared library, which is about 85MB, gets mapped to the process
virtual address when it is initially loaded by dlopen(). However, only the pages needed
by the application are actually mapped to the physical memory, and they get swapped
out by OS unless re-used. The data shared library is loaded as a shareable read-only
const data. Therefore, a process memory map should show that it is shared among all
Apache processes.'
Some linking quirks on various platforms were ironed out pretty early, but on Solaris, if
you have metalink access, check out bug 4304233 .

Windows 7, Oracle DB, Instant Client and VBScript

I'm trying to to connect to a Oracle database via vbs on a Windows 7 machine using the instant client. I get an error [Oracle][ODBC][Ora]Ora-12560: TNS:protocol adapter error Code 80004005. Script still works fine in XP using the Microsoft ODBC for oracle. I've setup the system dsn, and added tns_admin option to the system environmental path. Here's the connection line
psconn.Open "DRIVER={Oracle in instantclient_11_2};SERVERNAME=192.168.50.1:1521/PSPRODDB;User Id=user;Password=pass;"
I've tried 32 bit instant client and the 64 bit and get the same messages with both. Any suggestions?

12560 means you didnt supply a tnsnames alias, and a database was not found in that home.
Try this:
"DRIVER={Oracle in instantclient_11_2};DBQ=192.168.50.1:1521/PSPRODDB;uid=user;pwd=pass;"

Hope it helps,

CR 2008 and ODBC connection using Oracle Instant Client driver?

Two questions.
I'm creating CR 2008 report using an ODBC connection. The ODBC driver is the Oracle Instant Client (version 10.2, I think.)
When I define the connection, I see only a few tables. I do not see the Tables, Views, Qualifiers tree that I see with a normal Oracle Server connection.
Does anybody know why this happens? Is there a CR ODBC driver that works better?
Second question: I have a .NET application that is pointing the report to another Oracle DB. In my db, table names are not unique -- each user has the same set of tables. I find that when the .net applciation sets the datasource, I get connected to the first table with a given name; I do not get the table scoped by the logon user.
In the .net application, how do I scope the table name to a particular user.
Any info helps. Thanks.
Tim

Hi Tim,
Below are the replies to your questions:
Answer 1: Please try the below steps:
- Make sure that in File->Options->Database Tab in the Data Explorer section the corresponding checkboxes are checked for tables, views,system tables,synonyms and stored procedures and the Table name LIKE and Owner LIKE boxes are blank.

Difference between instant client and full oracle client

Everyone,
I had read the below lines from a goldengate pdf. Someone please explain me what is the difference between instant client and full oracle client?
What is the use of XDK libraries.?
" The full Oracle client must be used with GoldenGate so that the GoldenGate programs
have access to the Oracle XDK libraries. Do not use Oracle Instant Client, which lacks
those libraries. You can download the full client from Oracle’s website."
Regards,
SAKTHi

The dealio is this:
When you install client software, you have several options as to the degree of what you get/install. The big chicken dinner is administrator, so you get all kinds of extra features, add-ons, libraries, utilities, etc. At the hard candy Christmas end is instant client, and that has just enough functionality to, as you may surmise by now, connect a client and that's about it. Various libraries have functionality built in to do whatever extra is required. An example is FAN, or fast application notification, used in Data Guard failover. A FAN API (Java) will detect a failover and re-direct a client connection to the new primary. What GG uses XDK for (specifically) isn't of importance to a user, just the fact that it is available for connecting to Oracle is.

Windows 7 64 Bit machine with Instant Client and 32Bit application

Hello everybody,
the last days a tried to get a 32Bit application to run on a Windows 7 SP1 64 Bit machine ... unfortunately with no success. The application runs on XP Pro and Vista Pro 32 Bit machines against a 11g RDBMS for years. As a refenence we use SQLTools from sqltools.net. It has nearly the same behaviour like the application, because it is a 32 bit application too.
First thing was to install a 64 bit environement to verify if the connection is allright.
- Downloaded instantclient-basic-windows.x64-11.2.0.2.0.zip an instantclient-sqlplus-windows.x64-11.2.0.2.0.zip
- Unpacked both packages into C:\oracle so that they reside in C:\oracle\instantclient_11_2
- Made a directory C:\oracle\tnsnames with tnsnames.ora in it, because the app uses it
- Set the environement variables TNS_ADMIN to point to C:\oracle\tnsnames and added C:\oracle\instantclient_11_2 in front of the path variable
- Restarted the machine
- Opened a commnd shell and startet sqlplus user/password@sid
Everything was allright, I was able to connect to the database as expected
Second thing was to start SQLTools, but as I feard it quitted with an error message when trying to access oci.dll of the instant client.
So i decided to switch to a 32 bit environement as a third thing.
- Downloaded instantclient-basiclite-nt-11.2.0.2.0.zip and instantclient-sqlplus-nt-11.2.0.2.0.zip
- Deleted the old C:\oracle\instantclient_11_2
- Unpacked both 32 bit packages into C:\oracle so that they reside in C:\oracle\instantclient_11_2
- Didn't change anything in the environement, because nothing changed from the view of the system
- Opened a commnd shell and startet sqlplus user/password@sid
But now I wasn't able to connect and got the following error
ORA-28547: connection to server failed, probable Oracle Net admin error
SQLPlus was able to start now, but when trying to connect to the database I got the same error like when connecting with sqlplus.
Does anybopdy have an idea how to manage to get a 32 bit application to run on a Windows 7 64 Bit machine?
Thanks in advance
My packages:
Windows 7 64 bit SP1
Oracle Instant Client basic lite 11.2.0.2.0
SQLPlus 1.5 22D

Have you tried WOW64 ? I have not used this emulator for sqlplus but it works for other 32 bit applications.

Using SQLDriverConnect with special characters in password fails, same info with ODBC (Oracle instant client) works fine

Hi,
on a windows 2008 machine that has the Oracle instant client 11_1 installed (11.01.00.06) i am calling SQLDriverConnect in the following way:
std::string str = "Driver={Oracle in instantclient11_1};Dbq=//10.10.101.66:1521/orcl;;Uid=myUser;pwd=a;b";
odbcRc = SQLDriverConnect(hdbc, NULL, (SQLTCHAR*)str.c_str(), str.size(), (SQLTCHAR*)szConnStrOut, 1024, &cbConnStrOut, SQL_DRIVER_NOPROMPT)) == SQL_ERROR);
as long as the password contains no special chars (namely semicolon) it works fine. but when I try to use special chars in the password It stops working, with an invalid username/password error.
State: 28000 Native error: 1017 Message: [Oracle][ODBC][Ora]ORA-01017: invalid username/password; logon denied
i tried different variations of adding " (\") over the password, over the entire pwd=a;b or braces { but nothing seems to work.
the thing is that using ODBC works! what I did was:
open ODBC, go to System DSN tab, add "Oracle in instantclient11_1", then fill the following information:
Data source name: Anything
TNS Service Name: //10.10.101.66:1521/orcl
User ID: myUser
then i press test connection, enter the password "a;b"
and it works!
I cannot figure out what's my problem.
Thanks,
Roy.

I've created your test table in my Oracle database using this extra character and I'm able to describe it properly.
SQL> desc test;
Name Null? Type
ATTIVITÀ VARCHAR2(40)
My character set being used is:
SQL> select * from v$nls_parameters;
NLS_CHARACTERSET
WE8ISO8859P15
NLS_NCHAR_CHARACTERSET
AL16UTF16
NLS_LENGTH_SEMANTICS
BYTE
So as long as it doesn't work for you in your native Oracle database I don't think it would work with DG4ODBC. So yes, it would be best to log a service request so that the Oracle database support can check out the NLS issue.

To be complete here the describe of the MySQL table native and using DG4ODBC:
mysql> create table TEST (attività Varchar(40));
Query OK, 0 rows affected (0.00 sec)
mysql> desc TEST;
---------------------------------------------------+
| Field | Type | Null | Key | Default | Extra |
---------------------------------------------------+
| attività | varchar(40) | YES | | NULL | |
---------------------------------------------------+
1 row in set (0.00 sec)
SQL*Plus: Release 11.2.0.2.0 Production on Wed Sep 28 09:20:17 2011
SQL> desc "gateway"."TEST"@MYSQL_DG4ODBC_EMGTW_1122_DB;
Name Null? Type
attività VARCHAR2(80)
So in general it should work.

Imp Exp utility in ubuntu 10.4 with oracle instant client 10

Hi,
I have a problem with the imp/exp utility on Ubuntu 10.4.
I have installed the oracle instant client 10, and I have followed this thread
[http://download.oracle.com/docs/cd/B25329_01/doc/admin.102/b25107/impexp.htm#CHDDBGDF]
So, I've set env variable in my .bashrc
ORACLE_HOME=/home/lucia/Programmi/instantclient10_1
export ORACLE_HOME
LD_LIBRARY_PATH=/home/lucia/Programmi/instantclient10_1:${LD_LIBRARY_PATH}
export LD_LIBRARY_PATH
PATH=/home/lucia/Programmi/instantclient10_1:${PATH}
export PATH
SQLPATH=/home/lucia/Programmi/instantclient10_1:${SQLPATH}
export SQLPATH
Sqlplus works fine, but when I try to use the utility exp/imp
exp DB_USER/DB_PW@DB_SCHEMA owner=DB_USER buffer=300000 LOG=DB_USER.log FILE=DB_USER.dmp compress=n
I have the following error:
No command 'exp' found, did you mean:
Command 'xep' from package 'pvm-examples' (universe)
Command 'ex' from package 'vim' (main)
Command 'ex' from package 'nvi' (universe)
Command 'ex' from package 'vim-nox' (universe)

Command 'axp' from package 'axp' (universe)
Command 'expr' from package 'coreutils' (main)
Command 'expn' from package 'sendmail-base' (universe)
Command 'epp' from package 'e16' (universe)
exp: command not found
(I cannot use data pump exp)
Any suggestions?
thanks in advance.

LuciaHello,
I had the same problem. It was related to the shell script interpreter being used: it is really a bash script asking to be interpreted as sh. For the impatient, the solution was to change the first line of the script orarun.sh to read as:
#!/bin/bash
Explanation:
1. The script runfixup.sh calls orarun.sh. The latter is the one that fails starting at line 845.
2. The script is really a bash script as can be seen from the if syntax used. For example at line 191 we see the double equall sign ==:
if [ "`echo $SET_KERNEL_PARAMETERS | tr A-Z a-z`" == "true" ]
3. The bash man page says:
string1 == string2
string1 = string2
True if the strings are equal. = should be used with the test command for POSIX conformance.
string1 != string2
True if the strings are not equal.
(End of man page excerpt)
Notice in particular that for a bash script to be POSIX it should avoid the == and just use =
4. orarun.sh has on its first line #!/bin/sh. On my Ubuntu system, sh is a softlink to dash and the dash man page says:
s1 = s2 True if the strings s1 and s2 are identical.
s1 != s2 True if the strings s1 and s2 are not identical.
5. So this script script uses bash syntax but is interpreted by dash. It is possible that this worked fine for the Oracle developer if on their system sh was softlinked to bash (which is often the case). Apparently, one should then be very careful to not use idioms that are not POSIX compliant.
6. Another solution is to change the /bin/sh softlink from dash to bash. Personally, I was less comfortable doing this (the possible repercussions were wider than the proposed solution above).
After making the change, the script ran perfectly. I think the best solution is for Oracle to update the script to be POSIX compliant or to identify itself as bash.
Hope that helped,
Mark Gaber

Oracle Instant Client for Intel MacOS X

Hi all, this is my first post here (so I don't know if it's the proper place, but to try it is free. Sorry for any inconvenience).
Anybody, can confirm/explain why, one year after launch, there isn't one available download of Oracle Instant Client for Intel MacOS X?
Without it's impossible, for example, to compile PHP with OCI support under Intel MacOS X (native mode) and it's really a pain.
With PPC version existing since ages, wouldn't be absolutely easy to recompile that cool stuff for Intel MacOS X?
TIA and ciao, Eloy Lafuente :-)

Hi again...
just to know a bit more... two months later... how is customer demand going...?
Have you searched for "macos x instant client intel" ?
Aren't PHP/Perl/Ruby applications enough?
I sincerely think it's a big mistake to don't offer native connectivity for MacOS X Intel users... of course, your mistake.
Some developers, like me, will stop developing/improving Oracle support in their applications just because they use MacOS X to develop. So, those applications won't run ok under Oracle, no matter where you deploy them.
With thousands of applications running natively under MacOS X Intel... isn't there (@ Oracle) able to recompile that tiny piece of software to run under Intels... sorry but I cannot believe it.
I'll email SJ right now! Ciao :-)
