How to define CPU sets for different hardware cores?
We're doing a small benchmarking research on parallel benefits of Niagaras, and as one part of
the research, we want to find out whether there are performance differences between hardware
CPU cores and strands within a core. From theory, only one strand of a core is executing at any
given moment, others are "parked" while waiting for IO, RAM, etc. So it may be possible to see
some difference between a program running with 4-processor "pset"s, i.e. 4 strands of one core
and 4 separate cores.
While I can use psrset or poolcfg/pooladm to create and bind actual processor sets consisting
of a number of processors, I have some trouble determining which of the 32 CPU "id numbers"
belong to which hardware core.
On a side note, an X4600 server with two boards lists 4 "Dual-Core AMD Opteron(tm) Processor
8218 CPU #" entries in prtdiag, but 8 "cpu (driver not attached)" entries in prtconf, and
Solaris recognizes 8 processors in pooladm. Again, there's no clue which of these 8 processor
cores belongs to which socket, and this information could be important (or at least interesting)
for SMP vs. NUMA comparison within otherwise the same platform.
So far the nearest ideas I got were from some blog posts about pooladm which suggested to
make a CPU set for a worker zone with CPU IDs 0-28, and moving hardware interrupts to CPU
IDs 29-31. I could not determine whether these are single strands of separate cores, or 3 of 4
strands on a single core, or some random 3 strands how-ever Solaris pleases to affine them?
Is this a list defined somewhere (i.e. IDs 0-3 belong to core 0, IDs 4-7 belong to core 1 and so
on, according to Document X) or can this be determined at runtime (prtdiag/prtconf)?
Is this a fixed list or can the "strand number-CPU core" relations change over time/reboots?
Perhaps, does Solaris or underlying hardware deliberately hide this knowledge from the OS
administrators/users (if so, what is the rationale)?
Finally, am I correct to believe I can place specific CPU IDs into specific psets via pooladm?
Looking at /etc/pooladm.conf I think this is true (the default pool lists all CPU IDs of the
system), but wanted some solid confirmation :)
Thanks for any ideas,

How to define a Value for an Attribute of an Class
Hi,
How to define a Value for an Attribute of a Class ...
( I need to change the value of an Attribute of a class in standard program ....
Ex...
cl_hrce_masterswitches=>infotype_framework_is_active
Here infotype_framework_is_active is the attribute .. its value in standard program is 'X'... Now i need to change it as ' '.
How to define it and set value as ' '.Hello Surendar
The static attribute INFOTYPE_FRAMEWORK_IS_ACTIVE is read-only and there is not SETTER method to manipulate its value.
However, the attribute is filled in the CLASS_CONSTRUCTOR:
METHOD class_constructor.
IF ce_is_active = true OR
global_payroll_is_active = true OR
mngmt_global_empls_is_active = true.
infotype_framework_is_active = true.
perid_infotype_is_active = true.
ELSE.
infotype_framework_is_active = false.
perid_infotype_is_active = false.
ENDIF.
ENDMETHOD.
Thus, you need to analyze how attribute CE_IS_ACTIVE, GLOBAL_PAYROLL_IS_ACTIVE and MNGMT_GLOBAL_EMPLS_IS_ACTIVE are filled in the CLASS_CONSTRUCTOR.
For sure you will find customizing settings that are responsible for this.

How to call hr_location_api.create_location for different address style with only those fields that belongs specific to that address style. It should decide at run time means at run time it will come to know the type of address style and based on that only the fields which belong to address details mapped to calling hr_location_api.create_location.
Thanks in advance.You can create a wrapper package on top of the API (hr_location_api.create_location)
In the wrapper package you set all the values dynamically based on your requirements(say the style and add_line columns are populated on your conditions) and then you call the API.
Does that not work ? -

How to define Approval Hirearchy for Fixed Assets?
Hello All,
Couls someone please tell me How to define Approval Hirearchy for Fixed Assets which should be different as compared to normal item purchase.Reply me ASAP

AdityaHi,
The AP invoice approval used AME rules for finding the approver. You can base you AME rules on virutally anything.
In this particular case, you can base your AME rules on one of the followings:
1. If any of the Distribution Accounts contain Fixed Assets natural account
2. You can define a separate document category which should be used with invoices for FA Purchase and use the category in AME rules to find approver
3. You can have a DFF at the Invoice Header level to indicate that this is a fixed asset purchase invoice and have this DFF to be used in AME rules.

How to define new colors for the form?(Finish)
Hello! Everyone!
I want to define new colors for the new form.
But I don't find where I can define it.
How to define new color for the form?
Thanks in advance!You have to set the Canvas color or as I said earlier you need to use one of the available color schemas on the OAS or Builder runtime.
If you want to use user defined colors in the builder, then you need to create a new color palette and use it.
I personally haven't tried it, but there is a section in the online help that describes how to do this.

How to define the texts for UI element Dropdownlistbykey?
Hi everyone,
I don't know how to define the texts for Dropdownlistbykey. It seems that Dropdownlistbykey has an attribute "selected key", but where can I bind the texts I want to display when user clicks the downwards
arrow?
Thanks in advance.hi,
you can use this code :
method WDDOINIT .
DATA : node_info TYPE REF TO if_wd_context_node_info,
value1 TYPE wdy_key_value,
set TYPE wdy_key_value_table,
k1 type string value 'M',
v1 type string value 'MAGO',
k2 type string value 'S',
v2 type string value 'Saurav'.
value1-key = k1.
value1-value = v1.
APPEND value1 to set.
value1-key = k2.
value1-value = v2.
APPEND value1 to set.
node_info = wd_context->get_node_info( ).
node_info = node_info->get_child_node('FOR_DROP').
node_info->set_attribute_value_set( name = 'DROP_KEY' value_set = set ).
I hope it helps.
Thanx. -

Edited by: [email protected] on 25.01.2010 8:36Hi there,
The size of an OLAP AW page is automatically derived from the block size of the tablespace in which it is stored (which in turn is typically derived from the db_block_size initialisation parameter)
Do you have a particular concern about this setting?

Best Way to Define Employee Numbering For Different Countries
HI all
I am working on for a project which will be for Multiple countries.But Each country has different Instances.Now the questions is What could be the Best way to Define Employee numbering for all the Regions ? As for as My knowledge goes It would be Number prefixed by Country.Then How we can have Alpha numeric in employee Coding ? We need to have Fast Formula to Ahieve this task.If any body has come across this scenario please share your thoughts .Any thoughts are greatly Appreciated.
Cheers
Kumar csIf you have each country on a different instance and you want employees to retain their employee number on transfer between countries, I believe you have two options:
i) Use manual numbering. One recent change to the system is that you can update the numbering profile from Auto to Manual and back to Auto again. So you could potentially leverage this manual workaround when a cross BG transfer happens.
ii) Bespoke module to export all emp numbers into a 'central repository', e.g., flat file, that can be accessed by all instances, imported regularly and then referenced by your Fast Formula. You would also need processing to determine when a person is a transfer from another BG or a new hire; probably have to be some control field on flex. Basically, this is a requirement made difficult by the decision to host each legislation on a different instance; I would never recommend clients to go down this route but I guess it's too late in your case.
If cross BG transfers are not common, e.g., less than 5 a week, I would recommend option 1. -

How to define Side Panels for linked to Child Window Applications
We are trying to use the NWBC Side Panel with PPM 6.0 in NWBC 3.5. We have a Role that has a menu defined that gives the users a link to the INM_WORKCENTER_APP which displays the current user's Tasks in a table.
When we click on a task in the table it opens the task details using the CPROJECTS_FPM application in a new window. This new window that opens up doesn't have any of the Side Panels that we have defined on the role with the main menu links.
We have tried to add the side panel using different application alias and at different levels in the Role, but can't get a Side Panel to show up on the child window. We even tried to switch the window to open INPLACE in the main window and it still switches to no side panels. The only side panels we are able to see is side panels that the user has manually added under connections and the Data Context Viewer side panels.
Is NWBC capable of having side panels to be defined to be available for these linked to child applications that are called from a main application screen? If so, what is the possible configurations we need to make on the role for this to work properly?
Thanks in advance for any help!Wanted to close this thread with the solution that worked for us.
We had to change the Launchpad configuration for Role CPROJECTS Instance OIF. We changed the Application from a Web Dynpro ABAP type to Object Based Navigation. Set the Application Parameters Business Object to PROJECT and Operation to DISPLAY.
Then for our role defined in PFGC for our NWBC, we added a new menu item to the Web Dynpro application CPROJECTS_FPM with Configuration CPROJECTS_FPM. Then under Object Based Navigation we set the Object Type to PROJECT and Method to DISPLAY to match what we set above in the Launchpad. Then set the menu item to be invisible since we didn't want it to show to users.
Now when we launch the child window it uses OBN and sees the definition in our role and utilizes the same Side Panel definitions defined for the role.
