ARD: Unable to get shared memory

Hi,
Has anyone encountered this problem with ARD 3.
As I try to open it it doesn't start and gives me get the following error message.
"The Remote Desktop Administrator software failed to start due to an unexpected error. The Remote Desktop software may not be correctly installed or the computer may require a restart"
Rebooting the server is no help.
ARD has worked flawlessly for 2yrs untill now.
When I check the console the lonly thing related to ARD there says:
"ARD: Unable to get shared memory"
Any suggestions?
//Carlos

It sounds like you have in incompatiblity between the version of the ARDAgent client software and the Remote Desktop Admin application on your admin machine. You should check the versions on both and make sure they are the same.

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".

1494 ERROR: xa_open() - failed to get shared memory

Hi,
I am getting the following error when I try to create a Q Space with number of
messages in it as 5,00,000. But if I try the same for 4,00,000 messages, it is
successful.
I checked the Shared memory in the machine and it is much more than it is required
for 5,00,000 messages Q Space.
Do I need to tune any other operating system parameter ?
1494 ERROR: xa_open() - failed to get shared memory, key = key, errno = errno
Description
While opening the queue space, xa_open() was unable to get the necessary shared
memory. The error number, errno, is printed in the message.
Action
This failure can be caused by a number of reasons but the most likely is that
either the amount of shared memory requested would cause an operating system tunable
to be exceeded (shared memory for the system or shared memory identifiers), or
another application is using the same key. Determine and correct the problem.
Thanks

Peter,
the errno value is 22
thanks

ORA-29855 - Unable to allocate shared memory

Hi,
We are encountering troubles (unable to allocate shared memory) while indexes creation. We tried to increase the share_size_memory (actually 52 mb) but this had no effect on this error. The Oracle error code is ORA-29855.
The database is version 8.1.7, hosted on a Linux machine (RedHat 7.2) with 512 mb of memory. The code used for the index creation works fine on other machines (code from 9iAS Wireless installation) running with Windows 2000 as operation system.
Any help or comment will be appreciated.
Thanks,
Fabrice Clari.
The error message is:
java.sql.SQLException: ORA-29855: error occurred in the execution of ODCIINDEXCREATE routine
ORA-13200: internal error [ROWID:AAAGDwAAFAAAAvjAAA] in spatial indexing.
ORA-13206: internal error [] while creating the spatial index
ORA-13011: value is out of range
ORA-00600: internal error code, arguments: [kope2ucoll700], [], [], [], [], [], [], []
ORA-04031: unable to allocate 16396 bytes of shared memory ("large pool","unknown object","koh-kghu sessi","kolcalm coll")
ORA-06512: at "MDSYS.SDO_INDEX_METHOD", line 8
ORA-06512: at line 1

Which portion of shared memory did you increase? The error indicates you need to increase large_pool_size. It seems you may also have other problems since you have several errors, and this only relates to the ORA-04031 error.

Q_CAT:1494: ERROR: xa_open() - failed to get shared memory

I am getting this error while booting tuxedo.
My question is how do I calculate shared memory on solaris and then which parameter to increase in /etc/system file.
Thanks

Vaibhav,
You need to make sure that the product of SHMMAX and SHMSEG is at least
equal to the total amount of shared memory needed by Tuxedo and any other
applications running on your machine.
"tmboot -c" will tell you the amount of shared memory required for the
Tuxedo bulletin board, but this does not include any space required by /Q.
To get /Q shared memory requirements, you can use the qmadmin subcommand
"qspacelist". If you have more than one queuespace on your system, you must
do this for each queuespace on your system, and add this total to the
bulletin board requirements. If any other applications on your machine use
shared memory, add their requirements as well. In case requirements change
in the future, it is good to add a comfortable amount of padding to this
sum.

Ora-04031 unable to allocate shared memory

Hi Guru's
Could some one help me in finding the sql's/program which causing the ora-04031 unable to allocate 3896 bytes of shared memory.
any suggestion is highly apprciated
Kind Regards

You may want to take look at:
ORA-04031: unable to allocate 4032 bytes of shared memory
>
ORA-04031 unable to allocate n bytes of shared memory ("string","string","string","string")
Cause: More shared memory is needed than was allocated in the shared pool.
Action: If the shared pool is out of memory, either use the DBMS_SHARED_POOL package to pin large packages, reduce your use of shared memory, or increase the amount of available shared memory by increasing the value of the initialization parameters SHARED_POOL_RESERVED_SIZE and SHARED_POOL_SIZE. If the large pool is out of memory, increase the initialization parameter LARGE_POOL_SIZE.

Unable to attach shared memory segment

Hi. I've installed a 8.1.5 database in Linux and configured DB_BLOCK_SIZE as 4K. My hardware is Pentium III 500 processor, 512 Mb memory size, 1.5 Gb swap memory and I'm trying to allocate 30000 blocks in database buffer cache (240 Mb), 50Mb in shared pool and processes=200. When I try to startup database it fails with ORA-27213 error. My kernel parameters are: SHMMAX=256 Mb, SHMMNI=1, SHMSEG=10, SHMMIN=1 and SEMMNI=100, SEMMSL > 210, SEMMNS > 410, SEMOPM=100, SEMMVX=32767.
What's wrong?

Hi MYH,
First, check to see if the OS still has the old heap allocated.
You don't say your OS, but try using "ipcs":
Use the ipcs –pmb command to identify all held RAM memory segments, the then use the ipcrm –m command to release the RAM memory from UNIX.
For (non_AIX) Use the ipcs –sa command to display held semaphores and then use the ipcrm –s command to release the held semaphores for the instance
As we noted in Chapter 1, we can create a single command to terminate all Oracle processes associated with your hung database instance.
root> ps -ef|grep $ORACLE_SID| \
grep -v grep|awk '{print $2}'|xargs -i kill -9 {} We can then check for held memory using the ipcs –pmb command and remove the memory held by the database:
root> ipcs -pmb

Shared memory segment: function not implemented

Hi!
I tried to install Oracle8 on a dual pentium II / 233 system
running Suse 6.0 (kernel 2.2.1, glibc6)
Everything went fine, until I got the message
"Database creation failed, see logfile"
The logfile /u01/app/oracle/products/8.0.5/orainst/install.log
tells me the following:
- Entering database actions section.

So, I guess it3s something wrong with the kernel. I did the
following:
changed in /usr/src/linux/include/asm/shmparam.h:
#define SHMIDX_BITS 16 (was 15)
#define SHMMNI 100 (was (1<<_SHM_ID_BITS)) #define SHMSEG
10 (was SHMSEG SHMMNI)
checked /usr/src/linux/include/linux/sem.h:
#define SEMMNI 128
#define SEMMSL 32
#define SEMMNS (SEMMNI*SEMMSL)
Compiled new kernel, rebooted, verified that the right kernel
was loaded, installed oracle new, but it still doesn3t work.
Have I missed anything ?
thanks

Hey, I ran into this problem too. Look and see if any db
processes failed to die last time you stopped oracle. I found a
ps_mon daemon still going when the database was down. I killed
it, restarted the database and everything was fine.

ORA-04031: unable to allocate 4096 bytes if shared memory

Hello Gurus,
Did anyone got this type of error before:
ERROR:
ORA-20414: Materialized View refresh failed - ORA-12008: error in materialized view refresh path
ORA-04031: unable to allocate 4096 bytes of shared memory ("shared pool","IDX_MIF_SITE","pacdHds_kkpaco","stP_kkpacd: kkpodPacdInit")
Every sunday full refresh of the data warehouse is scheduled. This sunday it didn't complete and gave us the above error. This can be solved by increasing the shared pool memory size. But DBA doesnot want to increase it every sunday(This has been going on for 3 weeks now) and it's not feasible to increase like this everytime.
We want to find the actual cause of it and fix?
Does anyone know the solution or can throw some light on this issue?
Thanks,
Sanjay

We want to find the actual cause of it and fix?The cause is simple - you have run out of memory assigned to the Shared Pool in the SGA.
The root cause is more of an issue. The Shared Pool is mostly used for keeping the SQL statements and supporting information (such as cursor support). Each unique SQL statement requires it's own area in the shared pool, however identical statements can used the same (shared) area. Shared Pool is also used to store the 'current' data dictionary (table, view, etc.) information. And in some cases, it's also used for 'large' operations such as direct path insert block builds.
Some of the possible reasons for running out of shared pool might include
- it's simply undersized;
- not enough SQL is actually shareable;
- the large pool has not been allocated.
That second one is frequent when the application builds up SQL statements by concatenating pieces, including literals (user input) and then executing the unique statement. This is a common technique by developers using .Net, Perl or having SQL Server background. (That mode of operation is very susceptible to SQL Injection.)
You can get a lot more info from:
- searching the forum;
- looking in the docco (Concepts manual and Performance Tuning guide);
- books, like Tom Kyte's "Expert One on One Oracle", "Effective Oracle By Design", and newer on apress.com

ORA-04031: unable to allocate 33568 bytes of shared memory in Oracle 10g

Whats could be the reason?

There could be a few reasons causing the problem. From literal message it would look like your shared pool size is small and you need to increase. But the root cause of the problem is a little more complicated than that. I suggest you read metalink doc

ORA-04301:Unable to allocate 8144 bytes of shared memory

I am using 64 bit version of oracle 10g Release 2 (10.2.0.1.0)
I am randomly getting this error. The full error message is below:
ORA-04301:Unable to allocate 8144 bytes of shared memory("large pool","COMPANYHISTORY","kxs-heap-w","qesaQBinit:buffer")
The table name keeps changing as the queries change. Similarly sometimes instead of "large pool" I get "shared pool" in the above message.
I tried increasing the shared pool size but the problem did not resolve.
Please help
Regards
Madhup

I have already tried that, but I am not able to solve the problem. Is there a way to compute how much space you should define for the shared pool, the large pool etc.

Unable to start DSC Shared Memory

I am running LabView 7.0 (I know its an older setup), with DSC and Lookout OPC to do Serial communications to an Omron PLC. I needed to update the Ni-DAQ because the PCI-6220 board needs the driver. I upgraded to NI-DAQ 7.5 and now a get the Unable to start the DSC Shared Memory Manager Service. I have uninstalled the DSC and reinstalled it with no change. I found in the discussion boards that I need nidscsm.exe in the windows\system32 folder but it is not there. I am running Windows XP.
I have 2 setups like this. 1 PC still connects to the PLC even though the error pops up, another PC will not connect at all, lights blink but then comms timeout error.
Thanks!
Solved!
Go to Solution.

NI DAQ is now out of date, if possible you should use DAQmx instead. According to this chart, you can use any version before DAQmx 8.1. This new driver should work better with DSC. If you need some help converting your code check out this tutorial:Transition from Traditional NI-DAQ to NI-DAQmx in LabVIEW

in my application we have on so called Master view which has 550 columns, this view is left outer join with 60 other views, something like
select c1
from   master_view
         left outer join v1 on --
         left outer join v2 on --
         left outer join v60 the compilation of the master view takes around 140 secs, but when i give grants to other users, or i re compile again, it shows me the error
ORA-04031: unable to allocate 128 bytes of shared memory plz assist me how i should resolve this issue,
Regards
nic

Hi billy,
your idea worked big big time,
i encaspulated all the outer joins views in small small views and finally build mv on each views,
the master view is plain equijoin, and has only 5 new mvs in its join condition,
the performance is increased tremendously,
thanks,
some times i wonder y i dont get such ides ;-);
all and all i can say,
good judgement comes from good experience, but good experience comes from bad judgement...
Regards
nic
