Number of processes exceeds maximum limit

Normally how many process we need to put in init.ora.
My database currently has processes=100 so Obviously sessions=(100 X 1.1)+5=115.
Some times we use to get Number of processes exceeds more than 100.
What does it mean. What is the preferable value for processes.
I have a thought to put Processes=300.
Regards,
Ganesh.

Dear Ganesh,
When you are getting the "Processes exceeded" error, your Oracle server is letting you know that the number of operating system processes has exceeded 100.
Go ahead and set:
processes = 250
in your INIT.ORA file. You have to then shutdown and restart the database for the changes to take effect.
Ciao.

ORA-Error: Maximum number of Processes exceeds

Hi,
Today we got one Oracle error: Maximum number of Processes exceeds while connects to our Oracle Database.
We have application running on our DB, which have 50 threads running and making connection to Oracle Schema.
In our init.ora file the Processes Parameter is set to 50.
But we also have another init<Schema Name>.ora file which has Processes Parameter as 50.
When I search on this error, I got that it is due to no. of user processes on Oracle instance.
What are these user processes exactly?
If we set the Processes Parameter as 150, and we have RAC environment with 3 Cluster, does it means we have 150*3 processes can run at a time.
The other doubt I have is that: Is this parameter is instance based, SID based or cluster based?
Please provide some input on this.
Thanks in Advance.
Manoj Macwan

If you don't issue
alter system set processes=150 scope=both sid='<your instance 1>'
all instances will be allowed to fork 150 processes.
The other poster is incorrect.

Amount of data has exceeded maximum limit - Infopath form

Hello, I am having a problem on O365 concerning an Infopath form.
The warning goes like this : " The amount of data that was returned by a data connection has exceeded the maximum limit that was configured by the server administrator"
Solutions exist for other version of Sharepoint/Infopath. I see in SharePoint 2013, this value is 1500 kilobytes by default
and we can increase the maximum size of that. However, in SharePoint Online, it cannot be changed.
Can you guys please help?
Thanking you in advance.
Regards,
Nite

Hi Nite,
You should ask this question in the Office365 forums:
http://community.office365.com/
But as this question has been asked before, it is not possible to change the limit in O365. Please see this thread:

Maximum number of processes exceeded 150

Dear All,
I have modified my init file and set the processes to 300 but I still keep on getting the above error.
When I issue the statment :
Select * from v$parameter where name='processes'
I get the value 300.
Why does the system message show 150 ?
How can I alter this ?
I have stored procedures which return ref cursors to the calling environment which is JSP pages.
We are closing the resultsets where ever the stored procedure are being called as soon as the processing is over.
How can I overcome this problem ?
Thanks in advance.

Oracle IIS number of processes grows to big

I am supporting a bad, packaged ASP program that runs under IIS.
IIS 4
NT 4
Oracle 8.1.6.0
After a few hours the number of sessions is about 25, which is ok, but the number of processes exceeds the limit (240).
We are investigating how this can be, but in the meantime I would like to automatically kill processes that are waiting, or belong to inactive sessions.
(By the way, is there a way to timeout sessions? or processes?)
My next task here is to see if any of them are locked, but I don't think so -- I think the web application is leaving them as orphans.
Thanks.

A bit more news. Basically the problem is identified by the fact that there are about 150 records in V$PROCESS that do not match to anything in V$SESSION.
I will reply when there is news about what is causing this.
You are right about MTS, if it is used in an IIS/ASP environment it will reduce the Oracle memory usage to about 4% of previous numbers. Amazing, MTS has connection pooling for cheap asp pages! (set it to multi, not dedicated).

Processes exceeded

Just recently started getting error message from Oracle 8i 'number of processes exceeded'. It is currently set to 50. The processes in Linux never seem to get killed. Our application is made up of web pages and a DLL running on IIS. Closing IE Browser however does appear to kill the processes after about 40 seconds.

I think this is a problem with dead database connections which is creating the problem for you.
These can be detected and killed by SQL*NET.
You may please try the following:
Step 01:Under $ORACLE_HOME/network/admin folder, go to the file "sqlnet.ora"
Step 02:Edit the file by adding
SQLNET.EXPIRE_TIME=n (Please specify a value for n )
This parameter will make SQL*NET send a probe every n minutes & kill all the dead connection processes.
Please note that this should be issued on the server side only.

ORA-00020: maximum number of processes (%s) exceeded

nobody was able to log into the database. when I tried 'sqlplus / as sysdba' I got : ORA-00020: maximum number of processes 1000 exceeded
database is 11.2.0.2 with patch 12
I've bounced the database and increased the processes..
my question is.. is there a way to tell what the processes were? what machine they were coming from? in a log somewhere..
Since I was unable to log in, I couldn't tell what had happened.. who was causing it..
if it happens again.. is there a way to log it?
also, this machine has DataGuard to a standby system.. is it possible for something to go wrong with dataguard and cause this?

You have only treated the symptom and not fixed the cause. As fellow members said, you could kill some "non-critical" processes and log in to the database.
But you will have to find out why there were so many processes in place. I am sure you might have set the definite number of processes after your planning before you went live. If you suddenly see too many processes, you will have to find out why and where they are coming from. Also check if there are any rogue processes.
To find out if there are any processes which have no sessions attached
select spid from v$process where addr not in (select paddr from v$session);
To answer your question, data guard shouldn't be affected by this. Nor would dataguard cause this issue in primary.
Fix this processes issue before it's too late. Otherwise, there will be a situation when you will have to keep increasing the processes until you hit the OS limit

Hi Jos
--> How to calculate ASM Parmaeter process? with which view i can get the information?
-->I cheked with below command by connecting ASM instance show below like 300 process .But while doing any operation on ASM crossing 300+ connection of process.
SQL>show parameter process
NAME TYPE VALUE
processes integer 300
--> I confirmed by checking by ps -aef|grep beq command in linux it shown 380 beq connection.
--> Power limit i given 5 while adding disks to diskgroup..!
--> long back ago we changed ASM Parameter process value to 300 in place of 100.
--> A question like while rebalancing is going node got hanged got alert error like ASM MAXIMUM PROCESS GOT EXCEED so no operation were allowed to the node, so we rebooted the node after rebooted node came in to normal state and able to do all operation normally..but my question is that rebalance is completed succesfully or not?
--> For this issue we need to apply any Patch to overcome this issue in future while doing any operation on ASM
Thanks a lot for your quick reply.

ORA-00020: maximum number of processes (500) exceeded

Problem Details:
In our Database we are getting huge number of open connection from remote system.
Let say, our application A and remote application name is B.
Some common users of application A are USER0, USER1, USER2.
Remote Application B uses USER0 to create views on application A's table through Database Link.
Those views (nearly 100) are accessed in application B at several places from the Java code.
Since those views are getting called almost all the times from the application B's code, DB link is in use almost all the time - holding many number of connections (check the first row of the query output).
Many times the open connections remaining high and any other application, users trying to connect to application A,
getting the ORA-00020 error.
Note :
1. Application B is very old application and does not use open DB link or close DB link.
2. Application B tried with "alter session close Database link xxx", it decrease the number of open connection but its degrading the performance of application B at large scale.
3. To cope up with this problem Application A recently incraesed the parameter process=500, but not sure if this limit can also be broken through Application B
Questions/Doubts:
1) What is best approach to handle this problem??
'alter session close database link xxx' is the only option from application B's point ??
What other approach can be taken??
2) We are not sure the risk associated with increasing the process parameter value ??
Appreciate your suggestion !!

ERROR:
ORA-00020: maximum number of processes (500) exceeded
Warning: You are no longer connected to ORACLE.

semmsl in Linux tells what the max number of processes are. You have to make sure this is equal to the process parameter of all instances plus 10.
It is usually in /etc/sysctl.conf
kernel.sem = 250 32000 100 128
SEMMSL
The SEMMSL kernel parameter is used to control the maximum number of semaphores per semaphore set.
Oracle recommends setting SEMMSL to the largest PROCESS instance parameter setting in the init.ora file for all databases hosted on the Linux system plus 10. Also, Oracle recommends setting the SEMMSL to a value of no less than 100.
SEMMNI
The SEMMNI kernel parameter is used to control the maximum number of semaphore sets on the entire Linux system.
Oracle recommends setting the SEMMNI to a value of no less than 100.
SEMMNS
The SEMMNS kernel parameter is used to control the maximum number of semaphores (not semaphore sets) on the entire Linux system.
Oracle recommends setting the SEMMNS to the sum of the PROCESSES instance parameter setting for each database on the system, adding the largest PROCESSES twice, and then finally adding 10 for each Oracle database on the system. To summarize:
SEMMNS = sum of PROCESSES setting for each database on the system
+ ( 2 * [largest PROCESSES setting])
+ (10 * [number of databases on system]
To determine the maximum number of semaphores that can be allocated on a Linux system, use the following calculation. It will be the lesser of:
SEMMNS -or- (SEMMSL * SEMMNI)
SEMOPM
The SEMOPM kernel parameter is used to control the number of semaphore operations that can be performed per semop system call.
The semop system call (function) provides the ability to do operations for multiple semaphores with one semop system call. A semaphore set can have the maximum number of SEMMSL semaphores per semaphore set and is therefore recommended to set SEMOPM equal to SEMMSL.
Oracle recommends setting the SEMOPM to a value of no less than 100.
App B could try using connection pooling or something to reduce the number of connections to the DB.

ORA-00020: maximum number of processes (25) exceeded ... uh?

Hello,
I'm trying to run a distributed simulation (13 programs x host,
16 hosts) that uses oracle (normally in an HP) against oracle on
linux.
I can't start all the programs, after about 20 clients (+-) no
other program will come up, and if i try to log to oracle with
sqlplus i get:
ERROR:
ORA-00020: maximum number of processes (25) exceeded
Is this a static limit imposed in the version oracle is
distributing for testing purposes?
Also, i notice that one server process is started for each client
program. So the distributed version doesn't support multithreaded
servers? Or may be i configured it wrong?

Question:

From the Oracle error message documentation:
ORA-00020 maximum number of processes (string) exceeded
Cause: All process state objects are in use.
Action: Increase the value of the PROCESSES initialization parameter.
Another alternative approach may be to configure your Connection pool and/or your ApplicationModule pool to optimize the use of
database connections and/or restrict the number of database connections used by the application. For example, if your application
has declared many root ApplicationModules (i.e. more than one ApplicationModule pool is in use) then it may help to enable the
jbo.doconnectionpooling switch so that each ApplicationModule instance in the pools does not maintain a dedicated database
connection while not in use. Another alternative if you are using the BC4J connection pool (not a JDBC datasource) may be to
restrict the number of connections the pool can create to < 150 with the jbo.maxpoolsize switch. However, please note that this
may have an impact on throughput.
- I intended to deploy my application to 9IAS server. Will the same problem occurs too?.
This is a database issue. So, yes.
Hope this helps.

Regards,
Bhavik Desai

You should check alert log file on database like Alex told you.
And please post Error ;)
But If You can access +ASM, Or ...by the way... if you stop database ... try to check ASM diskgroup.
$ export ORACLE_SID=+ASM1
$ sqlplus / as sysdba
SQL> set lines 130
SQL> set pages 10000
SQL> select NAME, TOTAL_MB, FREE_MB from v$asm_diskgroup;
If your DISKGROUPs for archivelog on DB full... backup or delete them
(please start database mount mode)
$ export ORACLE_SID=DB1
$ sqlplus / as sysdba
SQL> startup mount;
SQL> show parameter log_archive_dest
backup archivelog
$ rman target /
RMAN> backup ARCHIVELOG ALL DELETE INPUT format 'ARCH_%d_%U' ;
or delete
$ rman target /
RMAN> delete ARCHIVELOG ALL ;
After that ...
$ sqlplus / as sysdba
SQL> alter database open
This justs my suggestion, if your database has the problem with ASM diskgroup full ... because archvielog...
By the way... please post your result from ASM query and alert log file
Good Luck

Maximum number of mail processes exceeded

I've got problems with my mailserver. I already had them, but after a restart the problems didn't occur. From today after sys updates I have them back.
Some clients mostly iPhones can't connect to my mailserver.
In the system log I have the following error message:
Jul 26 15:07:49 miniserver dovecot[60]: Maximum number of mail processes exceeded (see maxmailprocesses setting)
I don't know where these settings are in a config file.
I also have problems with webmail, I I want to login I get an error message: Unknown error: Internal login failure. Refer to server log for more information.
Thanks,
Patrick

I found the config file and edited in: /etc/dovecot/dovecot.conf
Settings were: mailmacprocesses: 3
Changed it to 300 and voila.

Host SRVXXX is a server where a web app is and 192.168.1.1 is our firewall. May I think that this server was the one that made so many connections?
I checked alert.log, trc file and listener.log. What else can I check to determine what was the cause of this incident?

It could result from Denial of Service attack or trojan or virus infecting webserver
