-bash: ulimit: max user processes: cannot modify limit: Operation not permi

Hi,
Installed 10g Forms&Reports only on RHEL 3ES.
Modified /etc/profile according to Oracle's documentation:
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -n 16384
ulimit -p 16384
else
ulimit -u 16384 -n 16384
fi
fi
But when I logon to the server, the following message shows:
"-bash: ulimit: max user processes: cannot modify limit: Operation not permitted"
What is the problem here?
Thanks
Stephan

Changed Ulimits values for the Oracle user and getting error -bash: ulimit: max user processes: cannot modify limit: Operation not permitted when logging in.

I'm trying to increate the ulimits for max user processes and open files for the oracle user. I've set the values in limits.conf, /etc/profile and in oracle's environment scripts. Now when I log in as oracle I get the below errors. If I change the ulimits back to the original values errors go away but ulimits aren't changed.

Thanks for the update.
I modified the /etc/security/limits.d/90-nproc.conf and added a line for oracle and also modifed the oracle.sh file. The ulimits are setting correctly when I su - oracle but they are still wrong when sshing in as oracle.

/etc/profile: line 28: ulimit: max locked memory: cannot modify limit: Oper

Hi;
I writed one sh which is checking tablespace size and its working well ( i used this before for someother client) Now i try to run it on one server and i have this error:
/etc/profile: line 28: ulimit: max locked memory: cannot modify limit: Operation not permitted in /var/spool/mail/root
Anyone has idea what is problem?
Thanks

Well, check line 28 of /etc/profile, and see what command it is trying to execute. If it's a ulimit -l command, check if the value it is trying to set the limit to is higher than the current ulimit value of the current user. If it is, then that operation is not allowed. You can increase the limit for the current user (at login time) by modifying /etc/security/limits.conf . This is documented in the various guides, notes, whitepapers that talk about installing Oracle database on Linux.

-bash: ulimit: open files: cannot modify limit: Operation not permitted

Hi all,
i´m preparing a linux 64bits environment to install Oracle 10g R2. I´m following the installation manual and there say that:
Depending on the oracle user's default shell, make the following changes to the default shell startup file:
For the Bourne, Bash, or Korn shell, add the following lines in the /etc/profile file (or the /etc/profile.local file on SUSE systems):
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
Ok, I did it, so when execute the follow comand I get a error like this.
tetis:/etc # su - oracle
-bash: ulimit: open files: cannot modify limit: Operation not permitted
oracle@tetis:~>
Can anybody help me ?
Regards,
Wander (Brazil)

The limits for -u and -n are defined in limits.conf, it looks like the -n section is not working (-u is already 16384), just to double check, show us the output for:
$ more /etc/security/limits.conf | grep oracle
oracle              soft    nproc   2047
oracle              hard    nproc   16384
oracle              soft    nofile 1024
oracle              hard    nofile 65536
$ more /etc/pam.d/login | grep pam_limits
session    required     pam_limits.soEnrique

-bash: ulimit: pipe size: cannot modify limit: Invalid argument

Followed the Oracle documentation to install Oracle 10g R2 on RedHat 4(UP1) x86-64 and I'm getting the following error when I login to the server from a putty client:
-bash: ulimit: pipe size: cannot modify limit: Invalid argument
Can someone explain why I'm getting this error and if there is a way to fix it?
Thanks,
Denise

Hi!
Just delete changes in /etc/profile and make changes as shown here in file /etc/security/limits.conf.
Read this article:
Limiting Maximum Number of Open File Descriptors for the Oracle User
After /proc/sys/fs/file-max has been changed, see Setting File Handles, there is still a per user limit of maximum open file descriptors:
$ su - oracle
$ ulimit -n
1024
$
To change this limit, edit the /etc/security/limits.conf file as root and make the following changes or add the following lines, respectively:
oracle soft nofile 4096
oracle hard nofile 63536
The "soft limit" in the first line defines the number of file handles or open files that the Oracle user will have after login. If the Oracle user gets error messages about running out of file handles, then the Oracle user can increase the number of file handles like in this example up to 63536 ("hard limit") by executing the following command:
ulimit -n 63536
You can set the "soft" and "hard" limits higher if necessary.
NOTE:
I do not recommend to set the "hard" limit for nofile for the oracle user equal to /proc/sys/fs/file-max. If you do that and the user uses up all the file handles, then the entire system will run out of file handles. This could mean that you won't be able to initiate new logins any more since the system won't be able to open any PAM modules that are required for the login process. That's why I set the hard limit to 63536 and not 65536.
That these limits work you also need to ensure that pam_limits is configured in the /etc/pam.d/system-auth file, or in /etc/pam.d/sshd for ssh, /etc/pam.d/su for su, or /etc/pam.d/login for local logins and telnet if you don't want to enable it for all login methods. Here are the two session entries I have in my /etc/pam.d/system-auth file:
session required /lib/security/$ISA/pam_limits.so
session required /lib/security/$ISA/pam_unix.so
Now login to the oracle user account since the changes will become effective for new login sessions only. Note that the ulimit options are different for other shells.
$ su - oracle
$ ulimit -n
4096
$
The default limit for oracle is now 4096 and the oracle user can increase the number of file handles up to 63536:
$ su - oracle
$ ulimit -n
4096
$ ulimit -n 63536
$ ulimit -n
63536
$
To make this change permanent, you could add "ulimit -n 63536" (for bash) to the ~oracle/.bash_profile file which is the user startup file for the bash shell on Red Hat Linux (to verify your shell execute echo $SHELL). To do this you could simply copy/paste the following commands for oracle's bash shell:
su - oracle
cat >> ~oracle/.bash_profile << EOF
ulimit -n 63536
EOF
To make the above changes permanent, you could also set the soft limit equal to the hard limit in /etc/security/limits.conf which I prefer:
oracle soft nofile 63536
oracle hard nofile 63536

What's the semantic of "max user processes" (ulimit)

Hello everyone,
I don't understand the behaviour of ulimit, have a look at this shell dump:
$ ps hax | wc -l
120
$ ps h -u myUsername | wc -l
35
$ ulimit -Su 78
$ ps h -u myUsername | wc -l
bash: fork: retry: No child processes
bash: fork: retry: No child processes
bash: fork: retry: No child processes
bash: fork: retry: No child processes
bash: fork: Resource temporarily unavailable
$ ulimit -Su 80
$ ps h -u myUsername | wc -l
35
$
If I am currently running 35 processes, one would assume that >35 more should be sufficient to start two more processes - but obviously it isn't.
In this case, I needed at least "ulimit -Su 80" to start ps and wc.
If I set the "max user processes" limit to 79, the first four error messages change from "bash: fork: retry: No child processes" to "bash: fork: retry: Resource temporarily unavailable"
Can somebody explain this bevahiour to me, please? Why am I not allowed to create new processes, although the limits should be sufficient?

Apologies for the necro-bump but I hope this will help others.
ulimit -u does not give you the max number of processes rather it displays the max number of threads. To list the number of threads a user is currently using:
ps -L -u myusername | wc -l
The output from the above two commands can now be compared and allow you to set the appropriate ulimit.

Ulimit "cannot modify limit" error when starting Apache

This isn't exactly an OSX Server problem, but I am trying to start Apache and subsequently Tomcat on my MacBook Pro so I can locally test a website before I deploy it to our test server. (The MacBook is a new machine to which I recently migrated my setup from my old PowerBook. The PowerBook is running 10.4.11, FWIW, and all worked well there.)
When I do this from the command line:
sudo /Library/Apache2/bin/apachectl start
I get:
/Library/Apache2/bin/apachectl: line 70: ulimit: open files: cannot modify limit: Invalid argument
And Apache is not started. This runs fine on my old machine. The culprit line from apachectl is:
ULIMITMAXFILES="ulimit -S -n `ulimit -H -n`"
Just running the'ulimit -H -n' yields 'unlimited'.
What's the problem here, and how do I fix it? I haven't found the answer by Googling.

How to increas the max user process number in Solaris 11?

Hey
Could anyone told me how to increas the max user process number in Solaris 11? I tried below as described in https://blogs.oracle.com/hasham/entry/solaris_10_increasing_number_of , but it cannot work.
set pidmax=60000
set maxusers = 4096
set maxuprc = 50000
set max_nprocs = 50000
Thanks!

Perhaps you should work your original forum post:
Oracle 11g installation fail on Solaris 11 64bit - ORA-00443
through to a resolution before you complicate things that likely don't apply.
You make an assumption in that other post about exceeding various maximums. That may be true or it may not be true. Since the installation of a database program seems to be your actual expectation, go work that forum thread instead.

"at" command line broken in 10.10.3? I get "at: cannot regain privs: Operation not permitted"

After updating to Yosemite 10.10.3, I notice that I can't use the "at" command from the command line in my account. I get the error:
at: cannot regain privs: Operation not permitted
It does seem to work if I sudo, but I have some scripts which I don't want to change.
I don't need to do this very often, so something else other than the 10.10.3 update may have triggered this problem.
Solution?

Linc,
I tried creating the at.allow file, and it didn't help. It still gives me the same error message. Any other ideas?

Cannot open Sequence: "Operation Not Allowed" then "Out of Memory"

I quit FCS1 for about 5 hours and returned. When I opened the project I was working on I got these messages: "Operation Not Allowed" then "Out of Memory" when I attempt to open my master working sequence. Other sequences (small nests) do open within the project. The project opens, so the file is not corrupt. A back-up copy of the same project file on a separate physical disc generates the same results. I deleted the prefs and User Data folder, even ran FCP Rescue. Same results. Then I resorted to the Autosave Vault. The two most recent saves resulted in the same error messages. Fortunately the next did not. I lost a considerable amount of work. The system says my memory is OK (6GB). Any ideas? (An attempt to open on a FCS2 machine {8GB RAM} resulted in the same two error messages.)
The project is fairly lengthy (90 mins) and does have numerous 1 and 2 frame audio edits. Nothing particularly unusual in the video tracks--although I am mixing DV and HDV. It doesn't seem to me these attributes would matter, just throwing them out there.

...removing and re-rendering is a great idea, if you've got the time.
And if during render you get the same out of memory error, try rendering "in-to-out", rendering small chunks until you get to a chunk which brings up the error. Then, you've found an offending "corrupt" file.

This might be a stupid question but what happens when you perform a recon against AD? Once complete does the index list the account as confirmed, unknown etc?
