Processes Parameter in 11g

Hello,
Oracle offers licencing by the number of processes parameter. I want to increase Processes value to 300. let me know oracle recomends any licence aggrement? or we can increase
the processes parameter any value depends on the no of CPU's ? Is there any effect if we increase processes parameter to 300? FOR INCREASING THE PROCESSES PARAMETER ORACLE RECOMENDS LICENCE AGGREMENT?
NAME VALUE
processes 150
sessions 264
transactions 290
SESSIONS_MAX USERS_MAX CPU_COUNT_CURRENT
0 0 24
Above is the total cpu count.

Maximum value of Processes in Oracle 11g

Hi,
In our application, we do get the following error frequently.
ORA-12516, TNS:listener could not find available handler with matching protocol stack
When i searched about it, I learnt that the processes /sessions used might be exceeded.
So, I'm trying to alter the values of the system parameters - Processes & sessions for my DB.
The following link says the maximum value for PROCESSES is 'operating system dependent'
http://docs.oracle.com/cd/B28359_01/server.111/b28320/initparams188.htm#REFRN10175
The DB Host machine is Windows Server Enterprise and its 32-bit machine.
The DB is *"Oracle Database 11g Enterprise Edition Release 11.2.0.1.0"*
Can you please help me find out the maximum value of the PROCESSES parameter that we can set for this OS?
Let me know if my understanding of the issue is wrong.

Hi,
I checked the v$resource_limit table,
Resource Name    CurrentUtilization Max_Utilization Initial_Allocation Limit_Value
processes     119          150     150     150
sessions     124          158          248     248
I could see the current value for processes is 119 here. When i checked v$process few hours back, it was 145.
I could not use the command "ulimit -a" as its a DB installed in Windows box.
Can you help me to find out how i can find the value for Windows OS?
Thanks,

Optimal value of processes parameter in AMS instance

Hi
If we have several database instances on single server which are accessing ASM instance. How can we calculate optimal value of PROCESSES parameter for ASM instance
Here, I would like to mention that we are using Goldengate also for replication and for this our ARCHIVE DG is on ASM
Rgds
Harvindr

I have seen systems with multiple database instances (4-6) and running very well with just the defaults. That being said, follow the recommendations. GG, IIRC, talks to the database which does all of the reads/writes for GG. Therefore, 50+50*n RDBMS INSTANCES.
http://docs.oracle.com/cd/E11882_01/server.112/e10803/config_gg.htm
"Oracle GoldenGate 11g introduces a new optimized method of reading log files stored in Oracle ASM. *This new method uses the database server to access the redo and archived redo log files, instead of connecting directly to the Oracle ASM instance*. The database must contain the libraries with the API modules. The libraries are currently included with Oracle Database release 10.2.0.5 and 11.2.0.2. For information for accessing the API modules for other releases, see "Optimized Access for Oracle GoldenGate to Redo Log Files in ASM - for Oracle Database Releases other than 10.2.0.5 and 11.2.0.2" in My Oracle Support Note 1333171.1 at https://support.oracle.com/CSP/main/article?cmd=show&type=NOT&id=1333171.1 "

error occured processing parameter

Hi Satish,
I'm not sure.I have taken up this project recently and seeing lot of issues with the databases,might be lack of proper administration.
For some other database also I'm getting the same error for the parameter 'job_queue_interval'
SQL> create spfile from pfile;
create spfile from pfile
ERROR at line 1:
ORA-01078: failure in processing system parameters

If these are the parameters from oracle 8.1.7,can I comment these out.
or How can I resolve these issues related to the parameters.

Setting processes parameter

hi guys...
i'm using db rel 10.2.0.1 enterprise edition, windows server 2003 (32-bit) , on an average work day, about 150 users are connected through the application server to the database.
how does one know the appropriate value to set the "processes" parameter? what exactly does it depend on?
oracle documentaion doesn't help much, so if anybody can help, it would be really appreciated.

The Process parameter depends sort of on Sessions parameter. So if the number of sessions are 150 than settings Processes parameter to about 300 should be okay. There is no guidelines as such available which mentions how many to set. This is sort of a test-try kind of thing.
You can check a view though, V$RESOURCE_LIMIT to check that if you set Processes to N number, how many of them are actually being used by your db?

Error occured processing parameter

Hi,
I need to set new value for log_buffer. so what I did was i issued the following command at sql command prompt
alter system set log_buffer=50M scope=spfile;
it throws
ORA-012095: specified initialization paramer cannot be modified
so i brought the DB down and I made an entry(log_buffer=50m) in the initfile
and saved. Then, when I try to create spfile from pfile;
it throws error
ORA-91978:failure in processing system parameters
ORA-32003:error occured processing parameter 'log_buffer'
Due to this I couldn't resize the log buffer.
can anyone help me in how to set log_buffer
Please help in this..... I will e grateful to you
OS:AIX
oracle:10.2.0.2.0
Thanks in advance
With Regards
Boo

What are you trying to resolve or trying to accomplish?
Setting log_buffer to 50M doesn't make any sense at all,
as the log_buffer will be written when 1M is dirty or when it's one third full, whichever occurs first.
You are likely wasting some 45M of memory.

Enterprise Manager Exceeding Max Processes Parameter

We have a new install of 11.2.0.2 on OEL 5. We have the processes parameter set to 500 and sessions parameter set to over 700. We have EM database control setup and for some reason, it was using all of the processes making us unable to connect to the database. As soon as we shutdown dbconsole, the number of active processes went back down to less than 40. There were only 3 active users on the system. Anyone know why EM was making so many connections? Is this a bug?

There were various bugs in earlier versions (one says "This bug would have been fixed in old 11GC line which has been decommisioned."), look at the emagent.trc and see if has large numbers of uninformative errors. Do an SR, they'll probably uncaringly make you recreate everything and it will magically transform into different errors.

Oracle Processes parameter

Hi,
What does "Processes" parameter mean in Oracle 10g R2. By what I understand I understood that it is the maximum number of OS processes that can be connected to Oracle. Please correct me if I am wrong. How do we determine the number of processes that we need to decide? Also What if we give the number very high i.e say 1000 or 2000. I am asking this because, I was told that for every user connected to database a process is taken away. What if I specify my processes as 200 and 5000 concurrent users try to connect to database. What is the work around for this option? If possible what please explain me what kind of errors do we get when we give processes very less? What is the maximum possible number that can be given in any environment? How does it work in RAC 10g R2? Like, are the processes distributed to each instance exactly or it changes it number dynamically? Is there any way we can find how many processes each instance in RAC is using?

PROCESSES is a static parameter.
It can only be change by restarting the DB.
It is essentially the maximum number of concurrent users (sessions within the DB).
But each additional user slot consumes RAM/shared memory

Processes parameter

I have an Oracle 9i database.
Currently the processes parameter has been set to 500. In future the number of concurrent user processes will be around 2500.
How can I say whether my database will support those many processes based on x GB of physical memory or pga or sga size.
Thanks in advance.

I don't think there is any way, other than "testing", to certify whether your configuration will support those many number of users.
If you would like to verify how your system (configuration) would behave under load, try HammerOra. I love that tool.

Processes parameter does not changing

Hi All,
Resently we changed the processes parameter from 200 to 500 after changing we can see the new value as 500
when we restarting the DB using the script addbcctl.sh once again it showing 200
if we restart the DB(after changing the Processes parameter value) manually as sysdba user at sql prompt it is showing new value i.e 500 but if we restart the DB(after changing the Processes parameter value) using the script addbcctl.sh it is showing old value i.e 200
Please provide a solution out DB version is 10.2.0.3

Hi,
I believe this is because of pfile and spfile. The database script addbctl.sh use the pfile to bring the database up, while when you start the database manually via SQL*Plus it reads the spfile first. So, you can either make the addbctl.sh script read the spfile instead of the pfile -- See (Note: 457257.1 - How to use an SPfile with Auto Config ?) for details OR recreate the pfile from the spfile (take a backup of the pfile first, then issue "SQL> create pfile from spfile;").

OWB10gR2 process parameter error

Hi,
I have OWB 10gR2 with 2.6.4 Workflow on a 10gR2 database. I create a process flow in owb with a process parameter. The process contains a mapping with an input parameter. I bind the process parameter to the mapping parameter.
When I deploy the mapping to workflow I see that the mapping and process parameters are not deployed to workflow (wf_activity_attributes). And when I run the process from the control center manager and give a value to the process parameter this value does not appear in the runtime either (all_rt_audit_execution_params).
It works fine with OWB 9.2 and 10.1.0.4 as well.
Does anybody have an idea about this problem? What have been changed in R2 OWB in this territory? And how this problem can be solved?
Thanks,
Gabor

could you elaborate a little bit on that?
I have some issues with all my Process flows, after migrating from 10.1.0.4 to OWB10gR2.
When I try to generate the PF packages it fails with internal error:
oracle.wh.service.sdk.runtime.QueryException: null
- Internal Error Unknown System Parameter PARAM0 for executionAdapterId= 5 executionOperatorId= 1080
I can not delete this parameter from the process flow (the delete option is disabled when I click on in), and it doesn't complain about another parameter, PARAM, that I created after the migration.

Should i increase PGA when PROCESS parameter is increased?

DB version:10gR2
Currently our PROCESSes parameter is set to 500 and PGA_AGGREGATE_TARGET set to 700mb. We are going to increase init.ora parameter PROCESSES to 1000. Should i be increasing PGA_GGREGATE_TARGET as well?

Probably - but where are you going to get that memory from ?
When you set pga_aggregate_target, you are saying two things to Oracle. One viewpoint is that you are saying to that on average each process needs about N MB of memory (in your case about 1.4MB, which is a reasonable type of figure for an OLTP system). The alternative viewpoint is that you are saying to Oracle - ater startup and all other activity, this is the amount of memory available for Oracle processes so please ration it carefully.
If your viewpoint is the former, you need to set your pga_aggregate_target to something getting on for twice your current value. If your viewpoint is the latter, you can't change the pga_aggregate_target unless you get some more memory from somewhere else (e.g. the db_cache_size, or shared_pool_size).

Modifying Memory Optimization parameter for BPEL process in SOA 11g

Hello
I have turned on memory optimization parameter for my BPEL process in the composite.xml (11g)
this is what I have in composite.xml:
<property name="bpel.config.inMemoryOptimization">false</property>
How do we modify this parameter in the EM console at runtime? I changed this property to "true" using the System MBean browser, but it wasn't taking effect. I thought the SOA server must be restarted (similar to what we used to do in 10g). But when I restart the SOA server, the parameter goes back to whatever the value was in the composite.xml ignoring the change I made in the System MBean browser
Please share your thoughts.
Thanks in advance.

Deploying a newer version is not an option, as the endpoints could change (not sure if it would in 11g, but in 10g it does) and also, our service consumers will be pointing to the older version.As mentioned above, if clients are using URL without version then call will be forwarded to default version of composite internally. No manual tweaking required for this. Just make sure that while deploying the new version you are marking it as default.
Besides, we report on service metrics and having multiple versions just complicates things.Not at all. If you are not using versioning feature, you are really under utilizing the Oracle SOA 11g. Remember that metrics can be collected for a single composite with same effort, irrespective of the number of composite versions deployed. Only few product tables refer the version while storing composite name and rest all use only the composite name without version. I do not know how you are collecting service metrics but we use DB jobs for same it works perfectly with any number of composites having multiple versions deployed.
The idea is to do some debugging and collect audit trail in case there is a production issue by disabling inMemoryOptimization parameter. This is a live production environment and deploying whenever we want is not even an option for us, unfortunately. Why not debug by increasing log level. Diagnostic logs are the best option to debug an issue even in production. For getting audit trail you may re-produce the issue in lower environments. I think no organization will allow re-deployments just for debugging some issue in production until and unless it is too critical issue to handle.
Does this not supported in 11g? if it isn't, it does seem like a bug to me. You may always go ahead and raise a case with support.

Anuj

How to get the assignees for a specific role in process in BPM 11g

Hi, Gurus,
I am using BPM 11g. I am trying to retrieve all the assignees for a a specific role in process. It will be a parameter for a business rule to do further routing rule. But it seems there is no way to get the information. I found that there are Identity Service Functions in Human Task Assignment. But Identity Service Functions are not listed in Business Rule Activity, neither listed in other activities except Human Task Assignment. I cannot get the assignees in my process.
Is there any way to get all the assignees for a role? I also tried to retrieve the assignees out engine with Worklist API, but it cannot get either. Actually we can get all the assignees information in automatic activity in OBPM 10g. Maybe I am still not familiar with 11g. Any advice is appreciated.
FYI:
My scenario:
Suppose we have a role named ApprovalTeam. In this role, there will be several different department manager (BPM User) added in the role through Workspace. At run time, a request (With department info) with go through the approval by ApprovalTeam. A Business Rule Activity with decide which department manager will approve this request. Different department request will be dispatched dedicate managers, not all the managers in the role. I have an external JavaBean to get the department information from LDAP. To do the routing, I also need know all the department managers (BPM User) in the ApprovalTeam role. Then I can compare which department manager is matched with the request and assign the task to him.
Thanks a lot,
James
