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,

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

Regarding the Mandatory BackGround Processes

Hi,
I wanna to know the information abt the BackGround processes like(PMON,SMON,CKPT,LGWR,DBWR).Can u pls explain abt all these processes and can i able to visualise these processes practically?

To fully outline these processes and what they do, would take a book. In fact, books have been written on the subject.
Go to http://tahiti.oracle.com/ and start with the Concepts manual.

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 "

Reducing Windows Background Processes

I'm in charge of my company's data acquisition system and we've finally got everything running about how we want it to. The last issue we're having is that whenever the screen updates the program slows down measureably. I've got the program running in a loop that collects data, processes data, waits for user input, sends out commands to other hardware, and then repeats. The program is configured to only display one data point (64 channels, plus 5 on a chart and three other numeric gauge indicators) of every 100 collected. The effect this has is that while the program is not displaying data the loop executes in about 2-3ms, but that time jumps to ~60ms when it has to update the front panel.
My question is: how can improve the performance of my code on a windows XP system?
Is there some kind of indicator that I should use over another kind?
Does anyone have a guide on how to disable windows background processes (the computer the DAQ system is on isn't running much, but I'm not a very advanced user in that area)?
Any other general tips and tricks for this kind of problem?
I know the best solution would be to move to a real time operating system, but that just isn't an option right now. Any suggestions on how to improve performance on the system I've got would be appreciated.

Some clarifications, as requested. We're acquiring 32 analog channels and 32 thermocouple channels. The gauges and chart indicators are just a way of displaying a subset of the data in a more obvious form. All channels are also displayed in numeric indicators. The program is set up to run a loop with the following DAQ scheme: calculate a timestamp (relative to the start of the program), acquire a single scan of the analog channels, acquire a single scan of the thermocouple channels, and then do other data processing tasks. There's no set data rate, we're trying to acquire the data as fast as the program will allow, so the 2-3ms loop times is what we see in the output data file. One data point will occur at time 0.003, and then next would get the timestamp 0.006.
Every time the screen is updated, in the post-processing part, the time to execute the whole loop increases dramatically. In the data file we'd see a point recorded at time 0.006, and then the next one would be at time 0.066 (something to that effect). Since screen updating seems to be the cause of the slowdown I'm interested in what I can do to get that part to run as fast as possible.
We're running LabVIEW 7.1, and to get the screen to only update occasionally I have it set to keep a counter going that is incremented each time through the loop. If the counter gets to the value of 100, then in post-processing the current batch of data is sent to the front panel indicators and the counter is reset to 0. For all other counter values the data just goes into the output file and the screen indicators are left alone.

ABAP trail 7.00 timeouts and background process

Does anyone knows if it's possible to change the number of dialog and background processes?
And the transaction to change the timeouts of such processes?
Thank you

you can change the timeout in rz11.Parameter-name is rdisp/max_wprun_time. Backgound processes habe no timeout, so this value is only valid for dia-processes
To change the number, you have to adjust your instance profile. In the forum 'Netweaver Administrator' should be some information about that. So just the short hint: you can adjust the profiles in RZ10, but have to do some steps for that. Just search in NW-Admin-forum above.

Background Processing, Selection Screens and Variants

Hi All,
I am having a little trouble Background Processing with Selection Screens and Variants.
When a user runs my report and selects the option of background processing, then they select a checkbox.

BACKGROUND PROCESSING, REPORT NOT LOADING, "OBJECT NOT SET TO INSTANCE..."

Post Author: thecoffeemachine
CA Forum: .NET
I already posted this message in other Web sites, but I am almost getting crazy here and I need help:
HI:
The Web application I am testing was having several issues related to loading Crystal Reports. It was fixed and I do not know which of the 1000 things I did to fix it; but now it began, again, to have the same behavior after I had a conflict with another Web site that was in the same server.
The thing is that I had another virtual directory where resided a copy of the same Web app. for testing purposes/working with the Visual Studio. The reports were loading all fine, very fast, all perfect... And suddenly the assemblies of one Web site and the other began to "blend" together and..... well the same behaviors appeared again. I tried to copy the last stable backup and rebuild the Web app... but it did not work.
At the very first time that one requests the report, it shows without problem. At the second time it shows an error message related to "cannot submit to background processing", and sometimes "object not set to an instance.." ... and on the third time it just never shows up and the app. becomes unresponsive. I have to close the window and request the Web site again in another browser window. If I wish to see the report again I have to wait for hours until it shows it.
I am using Visual Studio 2003 and the Crystal Report version that was shipped with that Visual Studio version. I am working with Windows Server 2003 and SQL Server 2000. Below is the VB code:

I already have tried moving the Crystal Reports dll´s to the bin directory. ..... I have tried calling the Garbage Collector at page unload...I also have checked, inside the report, that the database is "up to date"... ... recycling the worker process of the IIS... etc...
I see that, in debbuging mode inside the Visual Studio, when the page loads the debbuging window shows a message notifying that the symbols related to the Crystal Reports dll's could not be loaded.
Should I need to modify the default properties of the database? I checked "database is case insensitive", "use indexes or server for speed".. I have tried checking and unchecking the box "performing grouping on server"
Oh by the way, my report has about 4 subreports in it. Each report loaded shows 1 or 2 pages.
ANY HELP WILL BE EXTREMELY APPRECIATED....

Measuring the value of "session_cached_cursors" and "open_cursor"

Friends ,
Recently In my Database production server Oracle10g (version : 10.2.0.1.0.), I got the "open_cursor" and "session_cached_cursors" related error where OEM asks to increase the value . I have increase the value but the problem still is not solved .
Can anybody plz tell me , how can I measure the Standard value of "open_cursor" and also "session_cached_cursors" of my database server ?
Another question ,
SQL> show parameter open_
NAME TYPE VALUE
open_cursors integer 500
In above output , what is the unit of 500 value . Is this value related with the SGA memory area ?

You can see the values of the parameters in your db with the simple show parameter command,
>
show parameter open_cursors
show parameter session_cached_cursors>
About the settings of the parameters and their optimal value, I guess there wont' be any "concrete" answer to that. Session cached cursors is set to 50 default in Oracle which means 50 cursors can be marked as 'hot cursors' for the the system and will be avoided from the library cache lookup. This also has a condition that the cursor will be marked as hot only when its run for 3 times. So you need to check back with your system that how many queries are actually requiring this optimization. And more over, this is used or said to be used when you are seeing a Library Cache Latch contention. I don't think that just for the sake of change, you need to modify the parameter from default.
The smae is true for the OPEN_CURSORS as well. The value is required to be changed if you are seeing an error about maximum opened cursor exceeding from the set value. Generally , a value of 2000 is enough for most of the systems but again, that may depend on site to site and surely enough , you need to check yours befoe playing around.

AQ Callbacks - Blocking background processes and best practices.

We are running several queues within our company and one of them uses pl/sql callback functionnality.
Basically, several triggers can enqueue a message when underlying tables are updated. The goal of the callback is to "treat" those messages, which means dequeuing the messages and passing them to some procedure (determined through a confguration table and the type of message). I don't know if i'm clear enough on this but it is as important.
In general the mechanism works perfectly but we noticed in one of our databases that, after a relatively big amount of messages enqueuing (~ 500-1000 in one trasanction), there are numerous background processes blocked on system table SYS.AQ_SRVNTFN_TABLEI. In fact, the queue starts growing and messages are not dequeued anymore by the callback, that doesn't seem to be executed anymore at all.
We actually were also unable to re-compile the package that holds the callback procedure nor removing/adding the reference of the subscriber to the queue with DBMS_AQ. It would hang there forever...
We are running Oracle Database 10g Enterprise Edition Release *10.2.0.4.0* and the value of AQ_TM_PROCESSES = 0.
I don't necesseraly have a complete and clear view of how the queue mechanism works behind the scenes so forgive for some foolish things I could say :-)
Diagnosis:
After some research, it seems the backgrounds processes are blocked on the system table SYS.AQ_SRVNTFN_TABLE on some index for MSGID.
If I understand correctly how the system works, the callback gets executed for a specific MSGID as we use it in the callback procedure to dequeue this message.
I've also discovered that the default value for the WAIT dequeue option is FOREVER...
So my idea was that, for some reason, the callback tries to dequeue a message that does not exist in the queue and... waits forever for the message to "appear".
This at first seemed pretty unlikely to me: why would the callback be executed if no message with provided MSGID exists... then you start doubting :-)
Attempt to resolve:
We've decided to alter the WAIT option to not let the dequeue in the callback wait forever.
We have made some tests (outside the callback) with NO_WAIT and also with a wait of a few seconds. Both solution prooved right so we added a wait of 60s in the callback and added some tracing.
Since then, no more background processes seems to hang there and we are able to alter the callback procedure normally. But with the added tracing, we noticed an unexplained behavior with the execution of the callback:
- callback runs
- ORA-25263: no message in queue QUEUE_OWNER.MULTISRC_NOTIFQ with message ID B4FFD1115523A46EE040007F0100304F
- callback runs again and message is dequeued and treated correctly
The first oracle error happens fast, not after 60s as the WAIT option specifies.
Questions:
<li>Is the way the callback method is implemented correct (see code below) ?</li>
<li>Do we need to commit in the callback method ? What implies committing or not ?</li>
<li>How wouold you explain the behavior of the callback after setting the dequeue WAIT to 60s and why it does not actually wait for 60s ?</li>

The configuration of the queue and the callback is as follow:
- the type of the payload is SYS.ANYDATA
- an extra index is create on CORRID column

Helping you with the specific issue is going to be difficult without direct access to the servers but given the importance this system seems to have to your business why are you not running on a fully supported version (10.2 has been in extended support for more than 6 months) and even in the current configuration not patched to 10.2.0.5?
My instinct would be to focus on moving to 11.2.0.3 as quickly as possible with a corresponding change to a current operating system version if your O/S is similarly out of date.
