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

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 "

Optimal value for shmmax and shmall

Hi Experts,
Am new to the database administration side. Need help/suggestions from you all. My requirement is narrated below:
I was going the kernel parameter for oracle 10gr2. But I have a doubt the following two parameters.
kernel.shmall=2097152 (Default)
kernel.shmmax=2147483648 (Default)
Also I know that this is the recommended value for these two parameters. But just want to check if I have physical RAM of 4GB then what should be the optimal value for these parameter.
Also can anyone suggest how to set the optimal value for these parameter.
Thanks

You can always set to the "Install" size and after it completes reduce them. You can move them down 25 to 30 percent in most cases.
The default size for SHMALL in RHEL 3/4 and 2.1 is 2097152 which is also Oracle's recommended minimum setting for 9i and 10g on x86 and x86-64 platforms. In most cases this setting should be sufficient since it means that the total amount of shared memory available on the system is 2097152*4096 bytes (shmall*PAGE_SIZE) which is 8 GB. PAGE_SIZE is usually 4096 bytes unless you use Big Pages or Huge Pages which supports the configuration of larger memory pages.
SHMMAX should not exceed 4294967295 on a 32-bit system. On x86-64 platforms, SHMMAX can be much larger than 4GB since the virtual address space is not limited by 32 bits.
If SHMMAX is too small, you can get error messages like :
ORA-27123
I almost always go with the recommended settings even on tiny 1GB systems.
With a 4GB system these probably are not worth changing.

Measure optimal values of background processes (RMON,PMON,RECO)?

Hi buddy's,
I am facing issue to determin optimal values of oracle EBS R12 background processes like (RMON,PMON,SMON,RECO)?
I want to determine and find it's maximum optimal values of each process with step by step guide because i am new in oracle.
My purpose is that if i found the optimal values of all background process then while during tuning it is clear for me to what i want to achieve.
Kindly help me and clarify this scenario how is it possible ?
Best Regards,
Waqar Arif

Hi,
You should learn some concepts first because you seem very very very new. RMON,PMON,SMON,RECO are background processes of Oracle database and there isn't anything called "value" associated with them. you can't control them or set any value for them. These are background processed which will rung when your instance will start.
See bellow for some concepts

How to choose optimal value for the OPEN_CURSOR parameter in init.ora?

15:05:35 SQL> select count(*) from v$open_cursor;
COUNT(*)
5159
15:06:28 SQL> select count(*) from v$open_cursor WHERE user_name='USER1';
COUNT(*)
2369
15:06:48 SQL> select count(*) from v$open_cursor WHERE user_name='USER2';
COUNT(*)
686
Currently, application using these number of open cursors?
How to set the optimal value for this application?

Hi,
>>With the above setting I have yet to get any errors due to cursor limits. A good trade off memory v issues.
To see if you have set OPEN_CURSORS high enough, monitor v$sesstat dynamic performance view using the SQL below for the maximum opened cursors. If your sessions are running close to the limit, maybe you should increase the value of OPEN_CURSORS.
select max(a.value) as highest_open_cur, p.value as max_open_cur
from v$sesstat a, v$statname b, v$parameter p
where a.statistic# = b.statistic#
and b.name = 'opened cursors current'
and p.name= 'open_cursors'
group by p.value;In addition, I advise you to take a look at your PL/SQL code in order to see if the explicit cursors have been close (if it was the case), or if your SQL code can be tuned ...

Error: Missing initial value for session parameter

Hi,
I'm facing a problem while running the ETL process for Complete 11.5.10 Execution Plan in DAC Client. Some tasks are getting failed beacuse of the following error:-

When i checked the parameter file i can see the value assigned to the $DBConnection_OLAP. The same tasks ran successfully when i ran the ETL process for Complete 11.5.10 for the first time. I did not change anything after that and also all these are came built-in with the installation of Oracle BI Applications.
Please anyone give me an idea what is causing the problem.
Thanks,

in DAC > Run History > Task Details, query
Name = SDE_ORA_Product_Category_Temporary
Open Status Description, look for string -lpf, the file after it is the actual parameter file DAC send to INFA server. E.g
-lpf D:\DACTOPUS\Informatica\parameters\SDE_ORAR12_Adaptor.SDE_ORA_Product_Category_Temporary.txt
Open the parameter file, most likely the [session_name] does not match with SDE_ORA_Product_Category_Derive_Full or some parameters are missing.

I suggest you upgrade your Oracle installation to 9.2.0.7 or 9.2.0.8 and then try again.

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.
Regards,
Tamil

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,
Tamil

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?

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.

"No sensor values have been generated for this instance." BPELConsole msg.

I've reworked the GoogleFlowWithSensors demo to use BAM sensors as a prelude to incorporating BAM into a a real BPEL process we have that's much more complicated. I've moved the schema in the GoogleFlowWithSensors.wsdl file to an imported XSD file as directed in literature. I created in BAM Architect a DataObject called ProcessExecutionTimestamp with 5 columns instanceId, receiveInput_TS, invokePartnerLink_TS, receivePartnerLink_TS, and callbackClient_TS. I was able to successfully tie the BAM sensors to this dataobject.
Everytime I test the BPEL process in BPELConsole, I get the results back but I get nothing but a "No sensor values have been generated for this instance." message in the BPELConsole "sensors" pane. I have found nothing in any BAM or BPEL log that indicates what could be going on.
Thanks in advance.

Hi,
BPEL Console does not show data published on BAM Sensors, to see on BPEL console you have use database sensor type.
Bpel log (default.log) shows any errors encountered on sending data to BAM.
Thanks

Process Diagram of an instance using PAPI

Hi,
I`m trying to get que Process Diagram of an instance with PAPI using processGetDiagram but it doesn`t work, any ideas or examples?
Thanks a lot

I dont think there is any way to update the value of any instance variable directly by PAPI.
What you can do is have a Global Activity with instance access from where you can access all the instance/ external variables.
You can call this activity using PAPI and can send arguments telling it what to do.
Let me know if this helps.

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.

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

Where="SysTabFunction.Level=1 and SysTabFunction.id=SysTabRoleRight.FUNC_ID And SysTabRoleRight.Access_Type='Y' And SysTabRoleRight.Role_Id=?
the Action In my struts-config.xml is :
<action path="/main" input="/WEB-INF/page/main.uix" type="oracle.jheadstart.controller.strutsadf.action.JhsDataAction" className="oracle.jheadstart.controller.strutsadf.action.JhsDataActionMapping" parameter="/WEB-INF/page/main.uix" name="DataForm" unknown="false">

]red]<set-property property="bindParams" value="SysRoleFirstLevelFuncTreeIterator=${sessionScope.UserInfo.roleId}"/>[red] <forward name="SysRoleSecondLevelFunc2" path="/StartSysRoleSecondLevelFunc2.do"/>
</action>
we can find the parameter is set in the error message.is it a bug?
thanks in advance
best regards.

Guo,
I see a question mark in the sql statement, instead of the Oracle-style bind parameter notation which would be ":1". Can you change your VO to use Oracle-Style bind params and see whether it works?
