How many GOLDEN GATE extracts should I create for 300 schemas

I have a question.I have 300 schemas and each schema has at least 120-130 tables which are not too big.I have to replicate all the schemas.What would be the best way to do it we have to also consider the memory we don't have much of memory available on source.I mean how many extract should I create.since it is also possible to create only one extract and we can add all schemas. what would be the best possible suggestion.should I create multiple extract lets say 10-20 and divide between them.or a single schema would be ok ??.
can anyone suggest me something !!!
Thanks in advance...

The limit of 300 processes (extract and replicats) per manager as raised to 5000 in v11.2.1.
You could certainly have 10 extracts:
Extract 1
Schema1.*;
Schema2.*;
etc
Extract 2
Schema31.*;
Schema32.*;
etc
The main things to think of:
Are their transactions that span schemas? Those should be in the same extract.
Can the extract keep up with the volume from those 30 (or more) schemas?
If I have to do maintainence on one schema and have to bring down the extract... are the other 29 schemas ok with this?
Maybe the volume is such that you can put all 300 in one extract?

ISCSI MPIO, how many path do I need to create

Hi,
I've a server with 4 NIC connection to a DELL MD32xx which have 8 NIC.
My question is how many path do I need to create under iSCSI connection.
Do I need to create a path from each Server NIC to each MD32xx NIC, which will make 32 connection (and doesn't make sense).
If not, how should I proceed, I've looked at many example and none seem to cover that kind of situation, they just directly connect the server NIC to the MD32xx NIC instead of going through switch for redundancy.
Thank
ML

Exchange 2010 SP3 - How many Calendar Items/Folders can you create under "all public folder"

Hi,
Is there a limitation on how many calendar items/folders you can create under "all public folder" in Exchange 2010 SP3?
Thank you

I don't believe you can create calendar items under the root folder, but it's been so long since I worked with a system that had public folders that I'm not sure. If you mean "a folder that can contain calendar items", that is not a calendar
item itself.
Now, I believe your underlying question is, "How many folders can be created at the root level of the public folder hierarchy?" If so, there is no simple limit that I know of (you can have thousands, if you really want), but management gets
pretty unruly with the more that you have. I normally recommend that you create sub-folders to logically meet your requirements, then have each of these with more folders (normally that only specific groups of users will be able to access or add items
to). And anyone will tell you that you want to restrict anyone from creating their own folders at the root level. In fact, this is the default setting for a new Exchange 2010 installation.
I'll add that you really should stop trying to use public folders, since there are newer technologies (SharePoint, for instance) that work much better and are much easier to use.

How many tempdb mdb files will be created in this case?

How many tempdb mdb files will be created in this case?
SQL Server detected 2 sockets with 6 cores per socket and 12 logical processors per socket, 24 total logical processors; using 24 logical processors based on SQL Server licensing. This is an informational message; no user action is required.
I have sql server 2012 enterprise edition 64 bit
Thanks

Its all upto your server usage and number of processors,
Note : If the number of logical processors is greater than 8, use 8 data files and then if contention continues, increase the number of data files by multiples of 4 (up to the number of logical processors) until the contention is reduced
to acceptable levels or make changes to the workload/code.
For optimal performance, you could add data files of the same size to tempdb up
to the # of processors on your server. So a 4 processor server should have 4
same-sized physical files for tempdb for optimal tempdb performance. The reason
you want the files to be the same size is because SQL Server tries to keep the
files filled to the same proportion. So if you had a 100MB file and a 200MB
file, SQL Server will try to keep them at the same fill level, for example 50%,
which means that the 200MB file will be written to approximately twice as much
as the 100MB file which reduces the performance gained by having multiply
files.

Report workload by calculating how many versions of SharePoint list items created in a certain time period

I have a total of 66 SharePoint 2010 lists - yes, 66! - each lists contains between 1500 and 3200 list items. My employees update these various list items throughout their workday. Each update to a list item creates a new version of the list
item. On average each list item will have anywhere from 5 to 10 versions before it is done. I need to create a report that tells me how many list items they've updated in a certain time frame. I have come close but still cannot arrive at
the data I'm looking for.
This is what I have so far:
I've created a report using SQL Report Builder 2008 v3 where I've filtered it to show only items MODIFIED between, for example, Feb1 and Feb28. Of those records, I want the report to tell me how many versions were created during that time
frame. The result is one list item with 5 total versions. Versions 1.0, 2.0, & 3.0 were created on 12/12/14. The last two versions, 4.0 and 5.0, were created on 2/24/15. Therefore, the answer I'm looking for is 2 because they
created 2 versions between Feb1 and Feb28.
However I get the following results using these queries:
If I do a =Sum(Fields!owshiddenversion.Value) in the expression field I get the total versions which is 5
If I do a =Count(Fields!owshiddenversion.Value) in the expression field I get the instance which is 1
Is there a way to count ONLY the number of versions created in a time period? Is there another hidden field in SharePoint that I can use in the expression that will give me results I'm looking for?

Hi Rafael70,
Per my understanding that you have already get all the need fields and informaiton of the updated version of list items and now you want to calculate how many versions of SharePoint list items created in a certain time period, you can't get desired result
using sum and count function, right?
I have tried to tested on my local environment but because I am not clear what is value in the field "owshiddenversion", I assumed you have two datatype parameters (StartDate and EndDate) to help filter the report in a certain time period.
Generally, if you have add the filter correctly, it will filter the correct number's updated version in this time period, I would like you to provide details information as below to help better analysis the requirements:
Could you please provide sample data of the table.
Please provide snapshot of the report structure you have currently designed.
Please try to provide all the expression you have used.
If you still have any problem, please feel free to ask.

How many symbolic accounts, I have to create and then assign them to res...

Hi friends,
I am in the BBP creation phase, I have created the list of wage types for my client, there are 41 wage types, now as far as posting to accounts is concerned, how many symbolic accounts, I have to create and then assign them to respective G/L accounts ?
Please throw some practical light on this, I know all theory 
Thanks
Jay

Hi Jay
We wouldnt be able to tell you exactly how many symbolic accounts you may need to create for the 41 Wage Types as it is specific to your requirement.
Check these links out: Symbolic Accounts..
http://sappeers.wordpress.com/category/sap-fi-hr-integration/
It might help you with a fair understanding of what you need to do.
Example for linking wage types to symbolic accounts: basic pay wage type u20181000u2019 is linked to symbolic account u20188888u2019 (Salaries & wages)
Hope this helped!

How to find the number of references created for a given object ??

How to find the number of references created for a given object in a big application environment.
That means, if i give any object name (of my application) as input, then how can i find the[b] number of references created for that particular object ??

Please do not post the same question multiple times.
As for your original question, there is no direct way to do it.
Especially not the way you phrased it,
since objects don't have "names".
Applications also don't have "names".
They have classes and instances.
Also, there are 2 related issues, and I'm not sure which one is the one you asked.
#1. Finding the number of references to the same object.
Eg.
Map<String,String> a = new HashMap<String,String>();
Map<String,String> b = new HashMap<String,String>();
Map<String,String> c = a;In this case, there are only 2 objects.
The first object has (at least) 2 references pointing to it.
The second object has (at least) 1 reference pointing to it.
(There may be more, if the HashMap library keeps
references to these things, or if the HashMap object has
some internal cyclic references...)
If you're asking this, then it can't be done.
It's an active research topic in universities
and software research labs, called "alias analysis".
Type it in google, and you'll see people are working hard
and having little success so far.
#2. Finding the number of instances created from a class.
In this case, what you have to do is to add a counter to
the constructor of the class. Every time an object is constructed,
you increment the counter. Like this:
   class MyClass
       public static int counter = 0;
       public MyClass( ) { counter++; }
    // Then later in your program, you can do this:
    MyClass a = new MyClass();
    MyClass b = new MyClass();
    System.out.println(MyClass.counter); // It should show 2Note: you won't be able to do this to every class in the system.
For every class you care about, you have to modify its constructor.
Also: when an object is deleted, you won't always know it
(and thus you won't always be able to decrement the counter).
Finalizers cannot always work (read Joshua Bloch's
"Effective Java" book if you don't believe me), but basically
(1) finalizers will not always be called, and
(2) finalizers can sometimes cause objects to not be deleted,
and thus the JVM will run out of memory and crash

Only one PR should be created for 3 months requirement.

Dear All,
In MRP run only 1 PR should be created for three months rquirement ,
Eg: The procurement is done only once in 3 months, means PO is raised only once in 3 months for a material. So now system should create only 1 PR [1 lot] for 3 months requirement.
I have tried to creating a new lot size in OMI4 and i assigned "No of periods" as '3', and assigned in material master, but still system creates PR many PR's. What could be wrong,
Thanks in Advance

How many Scan Listeners, we have to configure for 5 Node RAC?

Dear Professionals,
How many scan Listeners we need to configure for 5 Node RAC? Oracle will not allow us to create More than 3 scan's? What If i have one scan Listener per each for 1st 3 node's? what about remaining two Node's? How application user will connect to 4 or 5 Node? Can you please explain..? Forgive me, If am totally wrong?
Thanks
Sagar

Each of the 5 instances will register itself with the scan listener (using the instance parameter remote_listener). Thus, the scan listener is "aware" of the database instances on the other two nodes where it is not running. It can still redirect incoming connections to the local listeners on these nodes (registered as local_listener).

How many work processes are recommended by SAP for 16 GB RAM

How many work processes are recommended by SAP for 16 GB RAM ?

This is the calculation for determining the number of work process according to the available memory for the system.
- Number of dialog work processes = RAM/256 (min 2, max 18)
- Number of update work processes = RAM/768 (min 1, max 6)
- Number of update2 work processes = RAM/1024 (min 1, max 3)
- Number of batch work processes = RAM/1024 (min 2, max 3)
- Number of enqueue work processes = 1
- Number of spool work processes = 1

Yosemite mail v8.0 not showing how many messages are in a mailbox. For example inbox. Before upgrading it used to show how many messages you had in your inbox. anyone know how to switch "on" the number of messages?

Yosemite mail v8.0 not showing how many messages are in a mailbox. For example inbox. Before upgrading it used to show how many messages you had in your inbox. anyone know how to switch "on" the number of messages? Or has this feature been removed?

Agreed! This feature was very useful. If you find out how to turn it on, please let me know.
Apple, there is plenty of room in the window header all the way across on both sides of the word "Inbox". It's important to know many messages are in the Inbox. It provides a progress meter when you're cleaning out mail and striving for inbox zero.

How many times do you have to pay for Creative Cloud complete plan prepaid if it says an amount of money per year? do you have to pay that every year?

how many times do you have to pay for a Creative Cloud complete plan prepaid if it says an amount of money per year? do you have to pay that every year?

Perhaps the unclear part here is that the Cloud is a subscription offering. You never pay for it outright and never actually own it.
12 months pre-paid simply means paying the full 12 months subscription upfront. The following year, you do the same. And the same every year after that.
Like any subscription, if you want to keep using the software, you keep paying the monthly (or annual) fee every month (or year), year in, year out.
When you cancel your subscription, or it expires and you don't renew, then the software stops working.
