MQ tuning parameters for proxy poller

When configuring the MQ polling interval etc can someone advise whether it is possible to poll with a wait period; kind of like synchronous JMS polling but specifying a period to wait/listen before timing out?
At present we want to pick up the message as quickly as possible (since we have an SLA to turnaround a message within 2 seconds from arrival at MQ) and so we have a short 100ms polling interval but the problem is we have the CPU spinning at 30% (kernel time) which appears to be the polling only!
Ideally we'd make the polling interval 1000ms so long as the wait timeout was also 900-1000ms. Of course if all the implementation is rapidly polling within out "single" poll then the effect on CPU consumption would be the same.
Alternatively is there some other way of reducing the overhead of MQ polling (while retaining the ability to consume the message very shortly after it arrives)
regards

I think the default is unlimited. You can use these
params to tune your server.Thanks for response.
How do I know the baseline to set these parameters? What tool/utility can I use on Proxy server/Directory server in order to find the baseline for these parameters.
To make it more clear, how can I find from proxy server/DS server that how many currently simultaneous operations per connection are going on..
how many total operations per connection are running..
how many simultaneous connections to this group are running.
how may simutaneous connections per ip address are running.
Please let me know if you need further info.
Thanks again.

DB tuning parameters for APEX

I have APEX running on Large Linux box with DB version 11.1.0.6. The database was installed with the default parameters. I am seeing some sporadic performance where pages display fast 9 out 10 times, but the 10th time it takes a minute or so to display. Has anybody had any experience with DB tuning parameters needed for running APEX?

APEX uses shared_server so, depending on your workload, you may not have sufficient allowed. Check you shared_server parameter. You may need to increase it to accommodate more concurrent users. Other than that there is not much advice available until you tell us more. For instance, what do your database advisers reveal about shared_pool, sga, pga, db buffer cache...?

Recommended tuning parameters 10gAS 9.0.4 for 500 users

Hi,
we have Oracle 10gAS 9.0.4 deployed on multiprocessor windows using J2EE + WebCache type of installation
couple hundred EJBs, signed applet as the client gui
datasource connection pool using oracle thin driver
what would be the recommended tuning parameters for 500 concurrent users hitting this web/appserver?
Thanks,

Dear Malmstrom ,
Hope U R fine,
I am New to Oracle AS. We r deploying an application created in Oracle forms and reports 10g using Oracle database 10gR2 and FRServices 10g.
We r facing a no. of problems
1). A very frequently accessed form generates FRM-92102 while accessing using web.
while other forms seems to be ok.
2). We r facing Some times Reports generated using Oracle forms does not display page or hangs.
What we accessed is that We have just Installed Oracle FRServices and did not configured it.
Both oracle Database and FRServices are on one machine using windows 2000 Adv. Server which is an IBM dual processor machine with 2G RAM and 2G Virtual Space.
We r also going to shift Oracle database on RHEL 4.0 with Database 10gR2 using the same machine while we have planned to install FRServices on a seperate machine that is P4 2.8 with 1G RAM + 2G Virtual Memory.
Our requirement is that Maximum of 200 users with 40 concurrent sessions.
PLS suggest us the recommended settings for Oracle FRServices.
Thanks and waiting for ur reply.

Oracle 11g R2 Tuning Parameters

Hello,
I am trying to gather some basic tuning parameters for Adobe Livecycle application which can be applied on oracle database.
Are there any set values and configurations provided with Adobe as best practices apart from the ones mentioned during creation of database and schemas.
Thanks

Krishna Nazare wrote:
Hi,
This was useful. What i tried was that during instance creation i can run custom script. As part of custom script, i set the parameters and the script restarts the database instance. With that i am able to set the parameters and get the values set.
Thanks,
KrishnaWhat I'm missing is WHY?
Why are you concerned with not restarting the database? You are creating a database. That means there is no pre-existing database, no pre-existing application, no users. No one to care if you bounce it. So why is it important to NOT have to bounce it one last time after you have created it?
I'm glad you found a solution, but it appears to be a solution in search of a problem.

Mail constantly asking for proxy parameters

I am using the Apple Mail program to acess a corporate exchange server ; my company's network has a proxy ( which I know how to manage; I have input the proxy parameters into network preferences and web surfing is fine)
When I use mail ( and seems especially when I read emails with embedded graphics) I have dozens of screens asking (again) for proxy parameters
How can I input them one for once and get read of all those dialiogue screens ?

You may want to ask in the forum for the MacOS X version you are using. Mail is part of MacOS X. So ask in the Yosemite forum, Mavericks forum, etc.
Have you read the Help page in Mail "If Mail keeps asking for your password"? It may be a problem with your key chain, or a problem with your mail account on the provider's site.
If you entered the correct password in the password dialog in Mail, but continue to be asked for your password, try these suggestions.
In Keychain Access, locate and delete the email account password item.Open Keychain Access for me
In Disk Utility, select the volume (for your hard disk or disks) in the list, click First Aid, then Verify Disk. After you’ve verified (and repaired, if necessary) the disk, try sending yourself a message. Open Disk Utility for me

Best practice tunning parameters for tunning ADF apps?

Hi all,
I am tuning our 11g ADF app for around 3 billions (can be up to 10 billions records) and the concurrent connections up to 100. The app is running on a 16 core Intel chip and 8GB of RAM. The Weblogic used Rockit JDK. Any one have this experience please share and help me! I am considering what is the top ten crucial parameters for this tuning. Up to now I just have tunned some parameters from OS layer to app layers:
- indexing for queries
- open cursors, processes and pga memory
- share pool for app module and jdbc pooling.
- heap size of JVM memory only max value 1024 because of 32 bit Windows (Perhaps I must upgrade to 64 bit OSs to use more memory)
The app was tested with Jmeter with only 10 concurrent connection and the test case is logging in and query and logging out. It ran very slow. I found out that the weblogic server did not use CPUs equally (only 1-2 CPus were used)
Thank you and best regards.

New FAQ Entry on JVM Parameters for Large Cache Sizes

I've posted a new [FAQ entry|http://www.oracle.com/technology/products/berkeley-db/faq/je_faq.html#60] on JVM parameters for large cache sizes. The text of it is as follows:
What JVM parameters should I consider when tuning an application with a large cache size?
If your application has a large cache size, tuning the Java GC may be necessary. You will almost certainly be using a 64b JVM (i.e. -d64), the -server option, and setting your heap and stack sizes with -Xmx and -Xms. Be sure that you don't set the cache size too close to the heap size so that your application has plenty of room for its data and to avoided excessive full GC's. We have found that the Concurrent Mark Sweep GC is generally the best in this environment since it yields more predictable GC results. This can be enabled with -XX:+UseConcMarkSweepGC.
Best practices dictates that you disable System.gc() calls with -XX:-DisableExplicitGC.
Other JVM options which may prove useful are -XX:NewSize (start with 512m or 1024m as a value), -XX:MaxNewSize (try 1024m as a value), and -XX:CMSInitiatingOccupancyFraction=55. NewSize is typically tuned in relationship to the overall heap size so if you specify this parameter you will also need to provide a -Xmx value. A convenient way of specifying this in relative terms is to use -XX:NewRatio. The values we've suggested are only starting points. The actual values will vary depending on the runtime characteristics of the application.
You may also want to refer to the following articles:
* Java SE 6 HotSpot Virtual Machine Garbage Collection Tuning
* The most complete list of -XX options for Java 6 JVM

First of all please be aware HSODBC V10 has been desupported and DG4ODBC should be used instead.
The root cause the problem you describe could be related to a timeout of the ODBC driver (especially while taking care of the comment: it happens only for larger tables):
(0) [MySQL][ODBC 3.51 Driver]MySQL server has gone away (SQL State: S1T00; SQL
(0) Code: 2006)
indicates the Driver or the DB abends the connection due to a timeout.
Check out the wait_timeout mysql variable on the server and increase it.

Performance Tuning Guidelines for Windows Server 2008 R2 mistake?

Hi all,
I'm reading the "Performance Tuning Guidelines for Windows Server 2008 R2" and I think there is same kind of error. At page 53 there is a sub chapter "I/O Priorities" that explain how to handle I/O priorities.
In the guide it is said that in the registry I have to have a key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\DeviceClasses\{Device GUID}\DeviceParameters\Classpnp\
Where {Device GUID} I think it is the value I get in device manager under one of my disks -> properties -> details -> "Device Class GUID"
the trouble is that under the key HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\DeviceClasses\ I've no subkey matching my disk's device class guid! Maybe I'm drunk but I've checked every sub key under HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\DeviceClasses\
but neither of them as a subkey named "DeviceParameter"!!
So am I wrong?

Hi Andrea,
To find the "DeviceParameter", please try to follow the steps below:
1.Find this registry key and note the DeviceInstance value:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceClasses\
2.Find the device instance registry key under "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum" which contains information about the devices on the system and get the device interface GUID:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\<hardware id>\<instance id>\Device Parameters
I hope this helps.

How to log input parameters for Function Modules?

Hi,
I need to create a Logging system to trace input parameters for function modules.
The log functionality could be done by developing a class method or a function module (For example 'write_log'), and calling it within each function module that I want to log. The 'write_log' code should be independent from the interface of the Function Module that I want to log.
For example, I'd like to write a function/class method that can log both these functions modules:
Function DummyA
   Input parameters: A1 type char10, A2 type char10.
Function DummyB
   Input parameters: B1 type char20, B2 type char20, B3 type char20, B4 type Z_MYSTRUCTURE
Now the questions...
- Is there a "standard SAP" function that provide this functionality?
- If not, is there a system variable in which I can access runtime all parameters name, type and value for a particular function module?
- If not, how can I loop at Input parameters in a way that is independent from the function module interface?
Thank you in advance for helping!

Operation segment ---setup,
All operation in order will be reduce
Do not reduce,
Could any one light on this issue,
Thanks in advance,

Hi,
This error will come if you have not maintained Define scheduling parameters for production orders.
Check this order type whether linked with respective plant in OPU3.*And give production scheduler * mark ie, all.*
And in Define production scheduling profile - OPKP, link your order type in the page below.
In material master work scheduling view, input production sch profile or prod scheduler.

Srinivasan-
For creating a Generic extractor based on a FM, you first of all need to know what is going to be your structure.. i.e. what all fields you need to pull from what all tables. A functional consultant may help you identify the exact DB tables.
Once you know them, hand over the requirement and the pdf mentioned by Krishna to the ABAP guy, he would be able to take this up further.
Also decide 1st whether you would be using a full load or delta. There is a slight difference in the way they are built.
Let me know how it goes.

Parameters for opening PDF files in a browser

I read some of the posts about making a text link from an html page to a specific location in a pdf document in the browser. I set up the parameters, as I understand it, according to the document "Parameters for Opening PDF Files." The result from my test took me to the top of page 1, not to the bookmark on page 3 that I specified. See the link below. What is wrong with the parameters?
http://www.tabardtheatre.org/YPASCfolder/2012/SummerYouthProgram2012.pdff#page=3&bookmark= anniejr
You can also go to the website: http://www.tabardtheatre.org/audition.html and click on the text link (in blue).

The PDF Open Parameters do not contain the option to link directly to a bookmark, as was mentioned, but I've developed a script that can add this functionality to your files. Have a look here, if you're interested: http://try67.blogspot.com/2011/06/acrobat-link-to-specific-bookmark-in.html
