Limit on number of instances in RAC
Hi,
Is there any limit on number of Oracle Instances (other than hardware resources) in RAC environment.
Thanks
Manmohan
In theory, no. Certainly not one that you're going to hit unless you're planning on hitting a triple digit number of nodes.
In practice, as you add nodes, the scaling factor decreases, so adding nodes gets less and less bang for the buck as you add additional nodes. Most applications (particularly those not designed with massive scale-out in mind) have various bottlenecks that tend to get more and more apparent as additional nodes are added which require more and more tuning efforts to identify and remove. So your application(s) most likely impose much lower practical caps on the number of nodes than Oracle does.

Hello all,
I have been reading a lot of articles on the internet the last days on how to limit the number of instances for an asynchronous ftp process. I connect to an FTP every hour and transfer all the .xml file that are available. After FTP there is some more processing that has to be done.
For the moment when the customer uploads 20 files to his FTP, 20 instances of the same process are started. I want to limit this number to 5. I have been playing with all the possible parameters found on the internet and have been applying all the rules (like sum of workerbean and invokerbean ... sum of dspMaxThreads of all domains), but none of them worked !
I have put this process out of my production environment for the moment until I know how to control the number of instances.
The version I'm using is 10.1.3.3.0
If I don't get this solved I will be upgrading to 10.1.3.5 but I have no guarantee that the upgrade will do the trick ....
Home someone can help ...

How to limit the number of instances of an MDB?
Hi,
I am using jboss 4.0.5 AS, and we have an mdb which listens to the jboss's jms queue. We are using ejb 3.
we are configuring MDB like this
@MessageDriven(name="LongProcessMessageBean", activationConfig = {
@ActivationConfigProperty(propertyName="destinationType", propertyValue="javax.jms.Queue"),
@ActivationConfigProperty(propertyName="destination", propertyValue="queue/examples/OurSampleQueue")
@ActivationConfigProperty(propertyName="maxSession", propertyValue="1")
When there are multiple messages to the queue at the same time, it is creating multiple instances of the MDB, i want to limit the MDB instances to 1 ( I used maxSession=1, but it is not working).
When the messages to the JMS queue are increasing, after certain point it is saying that the unable to allocate memory....threadpool is full.
any suggestion would be appreciated............

How do I limit the number of Operator Interface and Execution instances to one?
We have a problem in MFG. The operator launches to instances of the operator interface and executes the same sequence. A second scenario is where the operator is executing the sequence and then changes from the execution window back to the Sequence Display window and launches a second execution window. We need to understand how to limit the number of executions within an instance of the Operator Interface to one. We also need to understand how to limit the number of instances of the Operator Interface to one.

Theoretical Limit for Number of Websites on Leopard Server
I understand that you can have several virtual websites on Leopard Server? Does anyone know what is the maximum theoretical limit for websites on a Leopard Servers?
Thanks,
Tricky RickyAt a minimum, you need to ensure that the SGA's for all the database instances are able to be loaded into the system's RAM. If you have 1 GB of RAM in a machine, and Windows and your other applications use, say 300 MB of that space, you would have 700 MB left for databases. If each database requires 200 MB of SGA, that limits you to 3 instances. You will also want to ensure that your PGA's are in RAM, which will further limit the number of instances. Assuming 70% SGA and 30% PGA, which is roughly what an average OLTP system would use, you would be limited to 2 instances on this machine.

How to limit the number of parallel instances of a given event-based job?
Hi,
DB version : 11.2.0.3
I'm using an event-based job with parallel_instances attribute set to true.
It works perfectly fine, messages are enqueued then dequeued and processed simultaneously by separate instances of the same job.
Now, I'd like to limit the number of parallel instances of this job running at the same time, say to an arbitrary number n.
What would be the best way to do that?
Maybe using a notification callback is a better option in this case?

How can I limit the number of rows returned by a select stat
How can I limit the number of rows returned by a select
statement. I have a query where I return the number of stores
that are located in a given area.. I only want to return the
first twenty-five stores. In some instances there may be over
200 stores in a given location.
I know is SQL 7 that I can set the pagesize to be 25....
Anything similiar in Oracle 8i?

Watch out. ROWNUM is run before ORDER BY so this would only
order the 25 selected

Hello everyone,
I just want to ask if there's a limit/maximum number of workflow instances for
a specific workflow label/identifier? From what I know, the label is just a label
for the user to identify the instances but it's not really a unique id for an
instance. So, many instances can have the same label but they are actually unique
from one another.
I'm asking this question because I'm having a bit of a problem with my workflow.
I'm using a particular label many times and WLPI creates many instances. But after
some time, it seems to stop creating new instances for the same label. Has this
happened to anyone else before? If so, how did u resolve it? If not, do you have
any suggestions how to go about this?
Thank you very much!Hi shannon,

How can I limit the number of attempts to print a web page
Hi I'm trying to find a resolution for an issue on our network.
We run several kiosk machines that allow customers to print out documents and web pages. However we are finding that we waste a lot of ink due to user's frequently sending the same print task to the printers.
Just yesterday we had someone print out over 70 pages because they just keep clicking print.
I've tried looking for an add-on that would address this but was not able to find one.
My question is this, Is there an internal setting that can be changed in firefox to limit the number of print attempts to say once every 30 seconds, or even a way to make a dialogue box come on screen saying that the print request is currently processing and not allow more printing until the current task is completed.Sorry, there is no setting within Firefox to prevent that from happening. Once the user sees the "native print dialog" box (what is seen when you do Ctrl + P to initiate printing), the operating system and the printer drivers take it from there.
I have seen something similar to that on kiosk / rental PC's in FedEx Office stores, that notify the user of the cost per page the user wants to send to a printer, and if the user should happen to click again to print the same pages again it asked if you want to spend another $x.xx to print a second copy. Wouldn't be too much different to just shut off the printing of multiple copies of the same document and notify the user of that action.
My advice is to discuss that with whoever set up those kiosks to being with. -
Limit the number of open production order
Dear PP experts,
I am working on discrete scenario where client want to limit the number of open production order per work center. The more elaboration is like, for one work center the only specific number of production should remain open (e.g. 5 production order in assembly shop) when user is trying to open 6th production order system should restrict that.
Does any standard functionality available in system or needs development?
Regards,
ShekharDear,
You can do it with avilability check for materail and capacity.
In OPJK do the for your production order type as no release if materail and capacity i missing.
Hope clear to you.

How to limit the number of rows in a report
I have several reports with a number of parameters - date ranges etc.
Depending on the parameter values selected by the user the reports can return thousands of rows.
I would like to limit the number of rows returned to, say, 500. If more than 500 rows are returned by the query then display an error message requesting that the user enter more specific parameters.
Ideally for performance reasons it would be good to catch the error before the datafile is generated, but I don't know if this is possible. Alternatively a check in the template might do the job - using COUNT on the group?.Hi Hugh,
In your query, you got to add rowum < 500 or some sort of DB specific limit to the row being returned,
this will help to stop the report to get more than 500 records and the report template wont have any restriction.
or
you can do that in template too, but i would not recommend.
In these both cases or in any case, you cannot give any meaningful error if it exceeds N rows,there is no option like this till now. -
How can I limit the number of emails retained on my ipad air?
How can I limit the number of emails that are retained on my iPad Air? Because of legal requirements of a long-term project, I cannot permanently delete emails relating to that project from my ISP's mail server. My gmail account contains over 17,000 emails and, upon setting up my new iPad, and updating to ios 7.1.1, I now have all 17,000+ emails taking up space. I would like to limit the emails by count as I was able to do on my old iPad running ios 5.1.1 OR to retain them based on date range. I have not found any instructions on the support discussions or general iPad blogs that allow me to do that. Any way around this problem?
I also miss the 5.1.1 mail search feature that allowed me to narrow the search by from/to/subject/all. Does anyone know if that feature is available using some little-known ios 7.1.1 feature?
Thanks for your help.jlfcba wrote:
IOS 7.1.1 doesn't show a "days to sync" parameter anywhere in SETTINGS/Mail,Contacts,Calendars/ACCOUNTS/GMAIL Account/ GMAIL Acccount Info. There is nothing in iTunes relating to such an option either. So, it seems I'm back to square one.
If you have a decent mail provider like Microsoft Hotmail or Outlook.com mail it does.
If you have Gmail it does not. Quite right. Gmail is rubbish. -
I have limited space on my new ipad. How can I limit the number of songs from my itunes on my imac from going to my ipad when I connect the two?
you can do this by keeping the external hard drive connected and doing the following
-hold shift key down on computer while opening iTunes and a prompt will appear to choose a library
-select choose library, iTunes should bring up your explorer windows where you can search for the external HD
-after you find the external HD find the iTunes folder you just copied to it
-after opening the iTunes folder look for the file that says iTunes library.itl or if you can't see that extenstion just look for a document looking thing in the iTunes folder that shows up as a database file
-double click the database file and boom iTunes should load your library without having to copy it to the computer
PS: do make sure that if you are going to do it this way, make sure that the external HD is connected at all times, because if you don't then you will get exclamation marks next to your iTunes songs
double PS: if you are unsure how to find out if the iTunes library file is a database file just right click it and choose properties and under the type it should say database file
hope this helps:)
