ORA-27123 Linux RH9 to Fedora C2

Hi all,
For some reason, I was quite happy with the performance of my little cute Application Server, it is a Redhat 9 with 512 MB RAM and 1 GB swap, I had installed Oracle 9i Database, and it was working perfectly,
tried to install Oracle 10g AS on it, and managed my way to get it partially working (or lets say not working).
then had an idea (apparently bad one) to migrate to Fedora Core 2 as it might have over come the bugs and limitations of RH9 (I guess I was wrong)
After the migration, Oracle 10g Application server runs perfectly but Oracle 9i keeps giving me the "ORA-27123" error, Note Fedora Core 2 installed kernel 2.6.5 without asking me !!! (and wiped my previous kernel 2.4.21) even the source!!!!!! Bad Fedora!
Searched every possible solution I know so far,
1) changing the shmmax in the kernel to 2 * 1024 * 1024 * 1024 =(2G)
2) increased my swap file
3) set the ulimits in /etc/security/limits.conf; althogh I wasn't able to ssh oracle after that but I used su - oracle instead (from root).
4) re build the kernel to 2.4.27 (latest known good for kernel 2.4)
5) increased the ulimits as per installation instructions.
Read virtually every solution came after Google search about "ORA-27123" and still no success.
So, if someone can give me a hint or a solution to my nightmare that would be really appreciated.
at least would have to catch some sleep !
Thanks a lot in advance.

Problem resolved by issuing
#relink all
it is a kernel related problem.

ORA-27123 error while creating database

I am using dbca to attempt to create a database after installing 9i on a dual-CPU linux box running Red Hat 7.3.
When I click 'finish' on the database creation wizard, everything appeared to be correct, but I receive an error message indicating that Oracle is unable to attach to shared memory segment.
Additional information is that the machine has 640MB memory and a 40 GB disk drive.
It seems like I may have received this during the installation process, but can't be sure. Would that indicate that the installation didn't complete successfully?
Any help would be appreciated.

Try this one
*ORA-27123: unable to attach to shared memory segment.
I saw this error only in connection with Oracle 9i R2 (9.2.0) installation.
This error message showed up when the Oracle Database Configuration Assistant was running. I executed the following command to temporarely increase the maximum shared memory size:
As root:
# cat /proc/sys/kernel/shmmax
33554432
# echo `expr 1024 \* 1024 \* 1024` > /proc/sys/kernel/shmmax
# cat /proc/sys/kernel/shmmax
1073741824
Then click "Retry" for the Oracle Database Configuration Assistant.
It is recommended to increase the shmmax setting permanently for Oracle. So if you want to increase the maximum shared memory size permanently, add the following line to the /etc/sysctl.conf file:
kernel.shmmax=1073741824
I'm not quiet sure yet what the maximum size of the shared memory really should be. Also when you combine the Installation Guide with the Release Notes, you will see that other parameter(s) need to be changed as well. As soon as I have taken a
closer look at these issues, I will post the results here. But the temporary increase of the maximum shared memory size should keep you going to get Oracle9i (9.2.0) installed.

ORA-27123

This is the picture:
-Oracle 8.1.6 on Red Hat Linux 7.1
- Computer:
PIII 800Mhz
128MB RAM
64MB SWAP
- recompiled Kernel with values suggested by oracle for SHMMAX, etc.
I (apparently) succeed on installing the software, BUT as
suggested by several articles, I didn't create no database at all
from the OUI.
When the installation finished, I ran the dbassist to create a
new DB.
Again, as recommended by several articles, I didn't create the DB
from inside the dbassist, but saved the instructions to a shell
script file.
When I run the script it gaves me:
ORA-27123: unable to attach to shared memory segment
How do I solve this?
Same thing if testing manually with:
svrmgrl
CONNECT INTERNAL
STARTUP NOMOUNT
...)

Nope! same thing after adjusting those parameters...
When I did
.tstshm
it displayed:
Number of segments gotten by shmget() = 50
Number of segments attached by shmat() = 50
Segments attach at higher addresses
Segmentation fault (core dumped)
I'm sure this is bad, but I don't now what to do.
Any other idea?

Do i need to increase SGA_Target of my database that colud use more memory?If your database working properly without any issues/performance, Then no need to change.
Here nothing related to SGA_TARGET, if you want to increase memory for ORACLE instance, You have to increase SGA_MAX_SIZE , Moreover this is static value, you can change either in PFILE/SPFILE but not in memory , you have to bounce the instance for immediate changes.
SGA_TARGET is dynamic, once you set SGA_MAX_SIZE, then SGA_TARGET can grow upto SGA_MAX_SIZE.

ORA-27123 unable to attach shared memory segment

Running oracle 8.1.5.0.0 on Redhat 6.0 with kernel 2.2.12, I keep getting the error ORA-27123 unable to attach shared memory segment when trying to startup and instance with an SGA > 150 MB or so. I have modified the shmmax and shmall kernel parameters via the /proc/sys interface. The relevant output of ipcs -l is below:
------ Shared Memory Limits --------
max number of segments = 128
max seg size (kbytes) = 976562
max total shared memory (kbytes) = 16777216
min seg size (bytes) = 1
This system has 2gb of physical memory and is doing nothing except oracle.
I changed the shmmax and shmall parameters after the instance was created, was their something I needed to do to inform Oracle of the changes?

High JW,
i had the same problem on my installation.
The solution is written in the Oracle8i Administrator Refernece on page 1-26 "Relocating the SGA"
a) determine the valid adress range for Shared Memory with:
$ tstshm
in the output Lowest & Highest SHM indicate the valid adress range
b) run genksms to generate the file ksms.s
$ cd $ORACLE_HOME/rdbms/lib
$ $ORACLE_HOME/bin/genksms -b "sga_beginn_adress" > ksms.s
c) shut down any instance
d) rebuilt the oracle exe in $ORACLE_HOME/rdbms/lib
$ make -f ins_rdbms.mk ksms.o
$ make -f ins_rdbms.mk ioracle
the result is a new oracle kernel that loads the SGA at the adress specified in "sga_beginn_adress".

I did a clean installation of RHEL4 from scratch, but still the solution you suggested did not work.
Other info:
During pre-requisite checking - oracle alerted me :
- it expected value for shmmax = 2147483648
- it expected package openmotif, it not found openmotif
(in the system exists openmotif21-2.1.33-11.RHEL4.4 and openmotif-2.2.3-9-RHEL4.1 )
I ignored the errors and continued, but i still get the same error:
"ORA-27123: unable to attach to shared memory segment"
Thanks for help.

Errors - ORA-01034, ORA-27101 & Linux-x86_64 Error: 2: No such file or dir

I have installed Oracle 10g database and AS 10g on SUSE linux EE 10 (SP2)
When I try to log in as system/system using sqlplus locally on the server, it works fine. However, when I try the following I get error messages:
SQL> conn system/system@botsdb
ERROR:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Linux-x86_64 Error: 2: No such file or directory
I tried the same from my laptop through sqlplus and the error message is the same.
I checked if the database was up and to check this I executed follwing commands whicle still being logged as system/system:
SQL>Select * from v$database;
SQL>Select * from v$instance;
SQL>Select * from tab;
These do bring results. Also if I try to start up the database again, it gives error message that the database is already up. I have restarted the db number of times, checked if my listener was listening on the service BOTSDB and these all seem fine.
It is very intriguing that when @BOTSDB is attached while connecting, the connection fails.
Can someone please guide me to sort this error?
Thanks and kind regards,

Can anybody tell me to solve this issue in Linux? ( I am new in Linux OS)Hi,this error occur because *"soni"* entry(point) does not exits in tnsnames.ora file,this file must be located $ORACLE_HOME/network/admin/ location ,if does not exits then you can create this file manually or using netmanager.
1.Create tnsnames.ora file and add following lines(for example)
soni =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.10.201)(PORT = 1531))
(CONNECT_DATA =
(SERVICE_NAME = soni)
2.Or try following:(for example)
export ORACLE_HOME=/orahome/oracle/product/10.2.0/db_1;
$ORACLE_HOME/bin/./netmgrthen create this file using netmgr

Can anyone give me idea to increase the performance of Java1.4 in LINUX RH9

When we try to run Java Application/Code On LINUX RH-9.0 at the same time while running another application, which just a while loop to print out some data, the performance for Java application reduced.
In Java , we can run several application at the same time.
Can you please tell me how to make better performace JAVA 1.4 on RH9 LINUX while runing other application at the same time.
Please tell me why JAVA application is run slow in LINUX plateform,when running other application.

Ora enterprise linux and oracle 10g take 3

Hey;
This one doesn't seem so easy to work around. The oracle installer seemed to run fine all the way through to the point where it was creating a new database. I got an error stating:
ORA-19624: operation failed, retry possible
ORA-19870: error reading backup piece.
Ignoring it doesn't seem to do anything and aborting finally gets me out of the installer without a database created. I ran dbca and got the same error.
This sounds like I might have a borked oracle 10g download... does that seem right? The version is 10.2.0.1 Maybe I'll try the non-64 bit version.
thanks for any info supplied...
Doug O'Leary

Hey;
Thanks for the suggestion. That concerns me as the 64 bit oracle 10g download cksum is the same as listed on the download page. I may have some other issue going on here other than a bad download then...
Thanks.

Ora enterprise linux and oracle 10g take 2

Hey;
Ran into a snag and was hoping to get a tip from the experts. I installed oracle enterprise linux w/o issue and got everything configured per the installation directions. When I run the installer, I'm getting a library error:
Exception in thread "main" java.lang.UnsatisfiedLinkError: /tmp/OraInstall2009-06-09_09-51-41AM/jre/1.4.2/lib/i386/libawt.so: libXp.so.6: cannot open shared object file: No such file or directory
A google search result says that I'm missing the XFree86-libs which seems to be accurate as I don't see the rpm Oracle enterprise linux uses the xorg X11, not the xfree so I'm a little concerned about breaking something if I download and use that one.
A search on otn here shows that I'm missing the xorg-x11-deprecated-libs which is also true. I don't see that rpm in the list of ones on the installation media. I then searched through all the rpms on the install dvd for libXp and found nothing.
Should I find and download xorg-x11-deprecated-libs or is there something else that's not right? The verbiage says that oracle enterprise linux has everything I need so the apparent missing library probably means I screwed something up along the way.
Thanks for any info/hints/tips.
Doug O'Leary

Hey;
A little more searching later and I found most of the solution. It seems the libxp rpm didn't get installed. I installed that from the install media w/o issue. I'm still getting the same error though. I've confirmed that the library is now on the system and available in /usr/lib64 so I'm suspecting a library path issue.
If anyone knows how to set that in linux off the top of their heads, I'd appreciate the tip.
Thanks for putting up with me...

Installation of JRE-1_4_2-linux-i586.rpm: Linux RH9

I am kinda of a noob at this so this might be a really simple questions. I just recently installed jre 1.4.2, after following all the processes on the installion page it said this:
Preparing packages for installation...
j2re-1.4.2-fcs
[root@localhost backgrounds]#
The first question is do I need to take this further?
The reason for this question is I am installing LimeWireLinux and I got an error message like this:
[root@localhost backgrounds]# ./LimeWireLinux.bin
Preparing to install...
Extracting the installation resources from the installer archive...
Configuring the installer for this system's environment...
No Java virtual machine could be found from your PATH
environment variable. You must install a VM prior to
running this program.
[root@localhost backgrounds]#
So now it won't let me install LimeWire.
Thank you for your help.

I decided to answer my reply, since who knows maybe someone else need the same thing. This is thanks to Kevin from the olive.
This is for the newbies...
Ok, download limewire from the link above, make sure you have a java vm installed (j2re ...goto http://java.sun.com/j2se/1.3/jre/)
Log in as root.
Install J2, then find its path and version (try: ls /usr/java/j2*)
Before installing Limewire. vi (or however you create files) a file called java.sh :.Click on "more"
[root@localhost kevin]# vi /etc/profile.d/java.sh
enter the following:
JAVA_HOME=/usr/java/j2re...yourversion
export JAVA_HOME
PATH=$PATH:$JAVA_HOME/bin
export PATH
So my java.sh file looks like this:
JAVA_HOME=/usr/java/j2re1.4.1_02
export JAVA_HOME
PATH=$PATH:$JAVA_HOME/bin
export PATH
(note my ls /usr/java/j2* matches the first line in the above file)
Also change permisions to java.sh:
chmod +x /etc/profile.d/java.sh
Now log in as your user, and install Lime wire.
Once this new file is saved, you will need to type the above 4 lines you put in the java.sh file (again....do this as user, not root) into your command line or reboot. The reason is that this file is read during boot up, since you haven't done thatyet, your OS is not aware of java.sh . Here is the before and after so you see what I am getting at:
-----------------begin--------------------------
[kevin@localhost kevin]$ sh LimeWireLinux.bin
Preparing to install...
Extracting the installation resources from the installer archive...
Configuring the installer for this system's environment...
No Java virtual machine could be found from your PATH
environment variable. You must install a VM prior to
running this program.
[kevin@localhost kevin]$
[kevin@localhost kevin]$JAVA_HOME=/usr/java/j2re1.4.1_02
[kevin@localhost kevin]$ export JAVA_HOME
[kevin@localhost kevin]$ PATH=$PATH:$JAVA_HOME/bin
[kevin@localhost kevin]$ export PATH
[kevin@localhost kevin]$ sh LimeWireLinux.bin
Preparing to install...
Extracting the installation resources from the installer archive...
Configuring the installer for this system's environment...
Launching installer...
---------------------end-----------------------------------------
At this point a box pops up and the rest is point n click. Once installed you will notice in your home directory an new file called "runLimeWire"
[kevin@localhost kevin]$ ls runLimeWire
runLimeWire
So to run LimeWire type:
[kevin@localhost kevin]$ ./runLimeWire
...you will get a box pop up and your off and running......

Hi,
I am trying to build an example provided with RFCSDK. I have tried both procedures described in note 11682 (Perl script and modified compiler). In both cases when I link sapinfo.o with librfcum.so and libsapucum.so libraries, I get the following error message:
sapinfo.o(.text+0x160): In function `main':
: undefined reference to `RfcGetAllLibVersions'
sapinfo.o(.text+0x1da): In function `main':
: undefined reference to `RfcEnvironment'
sapinfo.o(.text+0x69c): In function `main':
: undefined reference to `RfcOpenEx'
sapinfo.o(.text+0x775): In function `main':
: undefined reference to `RfcCall'
sapinfo.o(.text+0x7b1): In function `main':
: undefined reference to `RfcListen'
sapinfo.o(.text+0x862): In function `main':
: undefined reference to `RfcReceive'
sapinfo.o(.text+0x8c0): In function `main':
: undefined reference to `RfcClose'
sapinfo.o(.text+0xd28): In function `rfc_error':
: undefined reference to `RfcLastErrorEx'
collect2: ld returned 1 exit status
What is wrong? I will be very grateful for any recommendation or help.
Thanks,
Elena
