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

Question:
- What is the cause of this error message? How to avoid?.
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.

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

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

Hi Everyone,
My Oracle database is 11g r2(11.2.0.2.0) and linux version is redhat 5.5.
In ASM one of our diskgroup getting full. so we added 5 disks to diskgroup with size of 545 GB lun(disk) each..succesfully added diskgroups but while rebalancing is going on ASM instance got stuck and node got hanged up and from application side process got stuck up and thrown with the below error from alert log, for temporariy solution we rebooted the first node.

PrasanthHi 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.
Thanks & Regards

I am unable to connect database this error ORA-00020: maximum number of
i issuing this command / as sysdba .getting this error

ERROR:
ORA-00020: maximum number of processes (300) exceeded
how to resolve this problem.it is verry verry urgent.Hi
"Maximum number of processes exceeded" will be alerted when your database has received a request for connection from a process which is beyond the number of processes your database can allow for.
Please check your database parameters
show parameters processes
Couple of options:
a) If your database has been running for a while and if it's the first time you are recieving this error, please check why all of a sudden more and more processes have been created. You may want to investigate your application, users, etc
b) If it's a valid request and if it's the case that you haven't really configured enough processes, you will have to increase the PROCESSES parameter in your init file and restart the database. It's not a dynamic parameter. Also, make sure you increase the sessions parameter as well along with the processes.
Before you do this, you will also have to check if your OS has been configured for increasing the number of processes. Think it's semmsl in Unix. -

Please help.
Thanks.i forgot shutdown abort. used that, created spfile from pfile, and it works ok now.

Maximum number of processes (100) exceeded
Hi!
I've some php application working with oracle XE with oci8 driver. Application works fine, but with time number of running oracle processes grows and when it reaches 100, it is impossible to to backup:
RMAN-00554: initialization of internal recovery manager package failed
RMAN-04005: error from target database:
ORA-00020: maximum number of processes (100) exceeded
To do a backup I need to restart oracle.
What is interesting, number of processes doesn't affect php application. I think php can reuse existing processes. It is possible that RMAN will reuse existing processes?
Or is there any way to close unneeded processes ?
best regards
JarekWith 11g XE, use DRCP connection pooling for your PHP connections. See The Underground PHP and Oracle Manual
Use non-DRCP connections for other jobs.
It sounds like you are using persistent PHP connections. This is good for performance but if you have a large number of PHP/Apache processes you will reach the DB limits, as you've found. You can tune the number of connections to suit the largest possible number of mid-tier processes in your system. Do this with the 'processes' parameter in the DB. See the "Configuring the Database For Testing" section in the testing chapter of The Underground PHP and Oracle Manual. You could also reduce the number of Apache processes that start, or be more aggressive in expiring them.
For follow up PHP questions, use the PHP OTN forum. -

PaulTellling the OpsTeam to ignore RMAN jobs that return errors is not an ideal solution.
Similar errors continue after upgrading to 12.0.4.2.
So the fix, does not fix all occurrances.

Ora-00020 maximum no .of connections exceeded
Hi All,
I tried to connect the production Db is says Maximum number of connections exceeded.
How to overcome this situation.
I stoppped and bounced the Db.
The process paramter in pfile is 50
Is there any to overcome thisc:\sql>oerr ora 00020
00020, 00000, "maximum number of processes (%s) exceeded"
*Cause: All process state objects are in use.
*Action: Increase the value of the PROCESSES initialization parameter.
Increasing the PROCESSES parameter as suggested by the error information would remove the issue.
If the database has been working fine for an extending period of time without this error you should consider finding out what caused the increase so you can set parameter appropriately. Could be an increase in use or an application leaking connections. -
ORA-01795:maximum number of expressions in a list is 1000
Hi,
JDev 11.1.1.5.0
I've a usecase, where i need to pass more than 1000 values for IN clause.
I found that, there is some restriction in number of values for IN clause to 1000.
I got following reference on this issue
ORA-01795:maximum number of expressions in a list is 1000. Any work around?
Conclusion:
there are two options to fix this issue
Fix 1:
You can have any number of tuples, not just 1000, in an IN-list like this:
(id, 0) IN ( (1,0), (2,0), (3,0), (5,0), (8,0), ... )
Fix 2:
Use global temporary table to populate values and then use the temp table
select * from table A1 where A1.ID in (Select ID from temp_table)
Please suggest the best option to fix our issue.
As of now, i am applying IN clause as
inClause = (1,2,3,4,5...)
criteriaRow.setAttribute("id", inClause);
I can prepare inClause as per Fix 1. But iam concern about setting attribute as (id,0)
can you suggest a way to apply as (id,0) IN (...)
Thanks in advance,
Samba.I would suggest fix nr 2. Since it's more flexible (for example when the list of items changes then you don't want to change every IN clause).

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 MacwanIf 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.
