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 .

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.

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.
Edited by: kgronau on Sep 28, 2011 9:21 AM
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

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:

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 :-)

Make sure that you have only one Oracle Client on the client machine.
Delete/uninstall all others. Best uninstall all Oracle Software on that machine and reinstall one client.
Before you try to connect from a PHP script, try to connect with sqlplus. If that works, proceed.
The PHP you use must compiled and linked against the Oracle client version you use, else it won't work.
Now try again. If you still get the same errors, post the error messages and relevant parts of the PHP script.
Be aware that this forum is for Instant Client, so there might be better forums for PHP questions.

ODBC Error: Could't find Oracle Instant Client in present directory.

I am getting the following error when I try to run odbc_install.exe with the Oracle 10g Instant Client Lite version 2:
Could't find Oracle Instant Client in present directory.
The 10g Instant Client Lite version (including the missing MFC71.DLL and MSVCR71.DLL files) is in the directory. What am I missing here??

Can you detail your configuration? What files are in the directories? Environment variables?

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.

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.
- Please try with OLEDB connection and check the results.
- You can also refer to this SAP note no# 1215994, the link to which is given below:
[https://websmp130.sap-ag.de/sap(bD1lbiZjPTAwMQ==)/bc/bsp/sno/ui_entry/entry.htm?param=69765F6D6F64653D3030312669765F7361706E6F7465735F6E756D6265723D3132313539393426]
Answer 2: If you are using RAS SDK only then you would be able to change table name. Please let us know if you are using RAS.
If you are using RAS with Java please post your query in the Java forum else if you are using Visual Studio/.NET then please post your question in .NET Forum.
Please update with the results.
Thanks!

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.
There's also this thread:

I had the same problem when I tried to compile directly from the client.
I can't find GLIBC_2.3.3 on FreeBSD 5.3.
Do you know if it works with another version of FreeBSD ? or should I install an emulator (I tried red hat 8.8, but doesn't work)? I tried to compile glib2.3.3, but it hasn't been ported on FreeBSD.
Anyway, I will try with redhat9.
Thanks,

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 libraries wouldn't install

I tried installing Oracle libraries (main file is called "oracle-instantclient-basic-10.2.0.4-1.i386", SDK and SQL according to the manual Oracle provides here: http://download.oracle.com/docs/cd/B1930601/install.102/e12121/insttask.htm#CIHEJFGF
After files is unzipped, manual instructs to use "runInstaller" command out of the directory where files are placed but this command is not recognized which tells me that either command file is missing or command is spelled wrong in the manual.
If anybody has successfully installed Oracle Instant Client on OS X 10.6 from the official Oracle download, please help! Thanks in advance.

Ok - I ran an ugly hack (similar to what I did with Linux) and manually moved files to locations which Oracle considers default and which do not require environmental variables, as follows:
When in the directory where Oracle client files were unzipped, run these commands:
cp sdk/include/*.h /usr/include
cp sqlplus /usr/bin
cp lib /usr/lib
Also, to be able to install OCI8 PHP module, following symbolic link will need to be created:
A symbolic link will need to be created as follows:
cd /usr/lib
ln -s libclntsh.dylib.10.1 libclntsh.dylib
I then installed oci8 for PHP and DBD::oracle for Perl and ran some test files, they work. However, if somebody knows why libraries didn't install with the command, as manual instructs, please answer! Thanks in advance!

Oracle instant client 11g doesn`t connect to database 10g

hi,
i installed a oracle instant client 11g for windows xp on my pc, because i need a odbc connection.
I don`nt know this product. I don`t find a tns.ora file, so how can i give them the right parameter for my oracle database and how can i make a odbc connection.
Is it already the right client?
Thanks in advance.
Regards
Nicole

Hi,
now 've seen that installed this client win32_11gR2_client this isn't the instant basic client.
Should i deinstall this client?
Or how can i make there a odbc connection?
Thanks
NicoleODBC sits on top of the Oracle client. (or any other native client of a given db product).
I don't think the ODBC drivers come with the instant client, though if you can locate a 3d party odbc driver for Oracle, that should work with the instant client.
Oracle ODBC drivers do come with the full client, but even there don't install by default - at least not up through 10g. In that case you have to select 'custom installation' (which can be done after a basic run-time installation) and select 'windows components'.

ORA-01816 when running with Oracle Instant Client

good morning
we are running the same SQL script on 2 computers.
- native system with DB
- via Oracle Instant client
when running via the instant client i get the following error.
( select to_char(to_date('1970-01-01') + "DATE" / 86400000, 'YYYY-MM-DD') "CD", logical_name
ERROR at line 2:
ORA-01861: literal does not match format string
thanks for any hint

It probably works on one and not the other because you have set the NLS_DATE_FORMAT for one system to match the format of the string you are passing in, so Oracle knows how to do the implicit conversion.

Oracle Instant Client is a memory hog?
