Pre-requisites for OS X 10.9 Upgrade??

Hello. I am considering an upgrade to my Mac OS (on both a Mac and a Mac Air). The details of my Mac are:
Processor 2.5 GHz Intel Core i5
Memory 4 GB 1333 MHz DDR3
Graphics AMD Radeon HD 6750M 512 MB
Serial Number C02H9SRGDHJF
Software Mac OS X Lion 10.7.5 (11G63)
At present the OS on both my Mac and MacAir is OS X Lion 10.7.5.
I have been considering purchasing OS X10.8 Mountain Lion but decided to wait until OS X 10.9 Mavericks was issued. This was because I did not see the point in purchasing OS X 10.8 just before it was about to be superseded by a new version OS (in this case OS X 10.9); and I was unable to ascertain whether OS 10.8 would be an essential pre-requsite for OS X 10.9 or not.
I have now seen that I can upgrade (free) to OS 10.9 Mavericks – straight onto my existing OS X Lion 10.7.5. This implies that I do not need to upgrade to OS 10.8 Mountain Lion beforehand. If OS X 10.8 it is not an essential pre-requisite for OS X, it seems to me that there is no advantage gained by purchasing it.
Please can someone advise me if there is any advantage in upgrading to OS 10.8 before going on to further upgrade to OS 10.9? Does OS 10.8 have any additional features that OX 10.9 Mavericks does not have, or needs in order to be fully enabled? In short, do I need OS X10.8 beforehand to take full advantage of the OS X 10.9 upgrade?
Any advice appreciated.

Nothing. OS X Mavericks has got the same features if you upgrade from OS X Lion instead of OS X Mountain Lion apart from the features that need a specific computer, so don't worry about it. Upgrading to Mountain Lion first would be a waste of money.
Open the Mac App Store and download OS X Mavericks. If your computer isn't supported, the Mac App Store will give you an error message. Make a backup of your files with Time Machine and check that your apps are compatible > http://www.roaringapps.com

Unicode Compatability is a pre requisite for ECC 6.0

Hi all,
Can any body send me any link or any document which says tht Unicode Compatability is a pre requisite for ECC 6.0. its really urgent.
Regrads,
Ruchika saini

Hi

The Link will be helpful to you.
Re: Upgrade 4.6 to ECC - What are the responsibilites

You need to use the transaction UCCHECK.
The report documentation is here
ABAP Unicode Scan Tool UCCHECK
You can use transaction UCCHECK to examine a Unicode program set for syntax errors without having to set the program attribute "Unicode checks active" for every individual program. From the list of Unicode syntax errors, you can go directly to the affected programs and remove the errors. It is also possible to automatically create transport requests and set the Unicode program attribute for a program set.
Some application-specific checks, which draw your attention to program points that are not Unicode-compatible, are also integrated.
Selection of Objects:
The program objects can be selected according to object name, object type, author (TADIR), package, and original system. For the Unicode syntax check, only object types for which an independent syntax check can be carried out are appropriate. The following object types are possibilities:
PROG Report
CLAS Class
FUGR Function groups
FUGX Function group (with customer include, customer area)
FUGS Function group (with customer include, SAP area)
LDBA Logical Database
CNTX Context
TYPE Type pool
INTF Interface
Only Examine Programs with Non-Activated Unicode Flag
By default, the system only displays program objects that have not yet set the Unicode attribute. If you want to use UCCHECK to process program objects that have already set the attribute, you can deactivate this option.
Only Objects with TADIR Entry
By default, the system only displays program objects with a TADIR entry. If you want to examine programs that don't have a TADIR entry, for example locally generated programs without a package, you can deactivate this option.
Exclude Packages $*
By default, the system does not display program objects that are in a local, non-transportable package. If you want to examine programs that are in such a package, you can deactivate this option.
Display Modified SAP Programs Also
By default, SAP programs are not checked in customer systems. If you also want to check SAP programs that were modified in a customer system (see transaction SE95), you can activate this option.
Maximum Number of Programs:
To avoid timeouts or unexpectedly long waiting times, the maximum number of program objects is preset to 50. If you want to examine more objects, you must increase the maximum number or run a SAMT scan (general program set processing). The latter also has the advantage that the data is stored persistently. Proceed as follows:
- Call transaction SAMT
- Create task with program RSUNISCAN_FINAL, subroutine SAMT_SEARCH
For further information refer to documentation for transaction SAMT.
Displaying Points that Cannot Be Analyzed Statically
If you choose this option, you get an overview of the program points, where a static check for Unicode syntax errors is not possible. This can be the case if, for example, parameters or field symbols are not typed or you are accessing a field or structure with variable length/offset. At these points the system only tests at runtime whether the code is sufficient for the stricter Unicode tests. If possible, you should assign types to the variables used, otherwise you must check runtime behavior after the Unicode attribute has been set.
To be able to differentiate between your own and foreign code (for example when using standard includes or generated includes), there is a selection option for the includes to be displayed. By default, the system excludes the standard includes of the view maintenance LSVIM* from the display, because they cause a large number of messages that are not relevant for the Unicode conversion. It is recommended that you also exclude the generated function group-specific includes of the view maintenance (usually L<function group name>F00 and L<function group name>I00) from the display.
Similarly to the process in the extended syntax check, you can hide the warning using the pseudo comment ("#EC *).
Applikation-Specific Checks
These checks indicate program points that represent a public interface but are not Unicode-compatible. Under Unicode, the corresponding interfaces change according to the referenced documentation and must be adapted appropriately.
View Maintenance
Parts of the view maintenance generated in older releases are not Unicode-compatible. The relevant parts can be regenerated with a service report.
UPLOAD/DOWNLOAD
The function modules UPLOAD, DOWNLOAD or WS_UPLOAD and WS_DOWNLOAD are obsolete and cannot run under Unicode. Refer to the documentation for these modules to find out which routines serve as replacements.

Anji

Pre requisite for Modification

Hi All,
Is there any specific pre requisites for Modification adjustments after prepare mode from abap prespective ?
We need to check these before we do an upgrade on the system from ABAP prespective.
Cheers,
Reddy

Hi All,
Upgrade document shows these are the planning steps need to take care .
Changes to the Translation of an Object Text
The changes are made in the translation environment (transaction SE63) or in the ABAP Workbench. An
SSCR key is not required.
Caution
Changes to translations of SAP objects are not retained when you perform an upgrade. They are
overwritten by a new version or deleted. For more information about retaining these changes, see SAP Note 485741.
Modifications to the Object
You may need an SSCR key to perform the modification adjustment. Get the key before you upgrade the
system. For more information, see SAP Service Marketplace at service.sap.com/sscr.
All modified standard SAP objects are displayed for adjustment in transaction SPDD or SPAU. Objects that
SAP no longer delivers are deleted. If you want to keep these objects, you have to accept the modifications
in transaction SPDD or SPAU.
Caution
Make sure that before the upgrade there is at least one package in the customer namespace (Z*). You
need this package if you have to create objects during the modification adjustment, for example, for an
append structure for customer fields of an SAP table.
You cannot create packages during the upgrade.
I have checked the prerequisites mentioned here .
When i run se95 i get 2 modification adjustments in red color under translations.
It shows there are transacation LSMW
Authorization Objects B_LSMW.
When i double click these two it traverse me to SE63 transaction. Please let me know what i need to check in these two entries in regard to translations.
Please let me what need to take care for these two before i confirm to BASIS team to go head with Upgrade.
Cheers,
Reddy

ADFS2012R2 Install: Why does this need Active Directory Domain Admin Account as one of the pre requisites for installating AD FS server

Team,
We were trying to configure AD FS through ADFS Wizard on Windows 2012 R2 box as part of ADFS upgrade from ADFS 2.0 to ADFS 3.0. But the installation got stuck in between as the domain account which we were using does not have admin privileges on the AD side.
We have to raise to AD team to elevate the rights of the service accountb we are using.
Can any one please tell me why having an admin AD account is pre requisite for the AD FS configuration, what are the "Write" changes which occur at Active Directory side post ADFS installtion, we need this details to supply to AD team for the justification
purpose.
Would appreciate any detailed response on this query
thanks
Lav

Hi,
dont know all exact objects ADFS is trying to create in AD, but it needs to create some container and objects under cn=Programm Data,DC=domain,dc=com for sharing certificates.
We had troube with this because the container does'nt exists.

What are the pre requisites for SPLIT VALUATION OF A MATERIALS

Dear friends
What are the pre requisites for creating SPLIT VALUATION for A MATERIAL in particular Plant
regards
Radha

Hi,
I am not sure what you mean exactly.
But you would need to have the valuation category and all of the valuation types created in config in advance.
Then you can allocate the appropriate valuation category to the material (accounting view) (as long as no stock or open POs etc. exist).
then you can create your additional accounting views (one for each valuation type that you want to use).

What are the pre-requisites for learning OA Framework?

Hi,
Im new to oaf,can any body help on this
What are the pre-requisites for learning OA Framework?
Karthik

In order to develop any OAF Application you need to know few concepts before doing any kind of development. The concepts are basically the Business Components for Java(BC4J) components.
They are:
Application Module(AM)
Entity Object(EO)
View Object(VO)
Association Object(AO)
View Link(VL)
Now let us see the description of each component.
Application Module:
Application Modules serve as a containers for related BC4J components. The pages are related by participating in the same task. It also defines the logical data model and business methods needed.They provide the transaction context and also used for establishing database connection. AM’s can be nested to provide more complex AM’s.
Entity Object:
EO encapsulates the business logic and rules.EO’s are used for Inserting,Updating and Deleting data. This is used for validating across the applications. We can also link to other EO’s and create a Association object.
View Object:
View object encapsulates the database query. It is used for selecting data. It provides iteration over a query result set.VO’s are primarily based on Eo’s. It can be used on multiple EO’s if the UI is for update. It provides a single point of contact for getting and setting entity object values. It can be linked together to form View Links.
Association Object:
An association object is created where we link EO’s. For example take the search page where we link the same EO to form a association between the manager and employee. Every employee should have a manager associated. But if it President then no there is no manager associated. This is a perfect example to understand the AO.
View Link:
A view link is an active link between view links. A view link can be created by providing the source and destination views and source and destination attributes. There are two modes of View link operation that can be performed. A document and Master/Detail operation.

Hi Friends,
As i am going through the implementation phase, I have to install sap router which i am new at. Also i am doing it because i have to connect Maintenance Optimizer to Sap service Market place for which Router would be essentially required.
I have some questions to put forth.
1. what are the pre requisites for SAP Router
2. Do we require Public IP and what would be the use of this ip
3. how to configure the SAP Router
4. Can i install the SAP router on the same host on which we have Solution manager, is it advisable. or we should go for a seperate host.

Installing the sapcrypto library and starting the SAProuter
Contents
u2022     Downloading necessary software components from SAP Service Marketplace
u2022     Creating the certificate request
u2022     Additional actions necessary before you can start saprouter
This section describes the necessary steps to download and install the sapcrypto library for use with saprouter. The saprouter must be started with the options described later in this section.
The license for the sapcrypto library covers saprouter connections between saprouters at SAP and the first saprouter on customer sites and backend connections within the customer`s network. For all other purposes the library CANNOT be used!
Downloading necessary software components from SAP Service Marketplace
1.     Login to the SAP Service Marketplace with the Service Marketplace USERID which is assigned to your installation.
2.     Change to the alias SAPROUTER-SNCADD. Before you can download the software components two preconditions must be met.
     a.     You must have been allowed to download the software. This authorization is added as soon as SAP has received a positive statement from the "Bundesausfuhramt". This procedure is necessary since the software falls under EU regulations.
     b.     For more information on how to obtain authorization if download is not possible see note 397175.
     c.     You must accept that you must follow the regulations imposed by the EU on the use and distribution of the cryptographic software components downloaded from the SAP Service Marketplace.
3.     The acceptance of the terms and conditions is logged with your USERID and stored for reporting purposes to the "Bundesausfuhramt".
4.     Accepting with the button on the web-based form takes you to the folder where you can download the Software components.
These are packed into a single CAR file sapcrypto.car
5.     Copy the file to the direcory where the saprouter executable is located
6.     You can get the file car.exe/sapcar.exe, which is necessary to unpack the archive from any Installation Kernel CD.
Executing the command car -xvf SAPCRYPTO.CAR will unpack the following files:
[lib]sapcrypto.[dll|so|sl]
sapgenpse[.exe]
ticket
Creating the certificate request
1.     As user <snc>adm set the environment variables
SECUDIR = <directory_of_saprouter>
2.     Change to the Shortlink SAPROUTER-SNCADD. From the list of SAProuters registered to your installation, choose the relevant "Distinguished Name"
3.     Generate the certificate Request with the command
sapgenpse get_pse -v -r certreq -p local.pse "<Your Distinguished Name>"
4.     Alternatively use the two commands:
sapgenpse get_pse -v -noreq -p local.pse "<Your Distinguished Name>"
sapgenpse get_pse -v -onlyreq -r certreq -p local.pse
5.     Display the output file "certreq" and with copy&paste insert the certificate request into the text area of the same form on the SAP Service Marketplace from which you copied the Distinguished Name
6.     In response you will receive the certificate signed by the CA in the Service Marketplace, cut&paste the text to a local file named srcert
7.     With this in turn you can install the certificate in your saprouter by calling
sapgenpse import_own_cert -c srcert -p local.pse
8.     now you will have to create the credentials for the SAProuter with the same program (if you omit -O <user>, the credentials are created for the logged in user account)
sapgenpse seclogin -p local.pse -O <user_for _saprouter>
9.     This will create a file called cred_v2 in the same directory.
For increased security please check that the file can only be accessed by the user running the SAProuter.
Do not allow any other access (not even from the same group)!
On UNIX this will mean permissions being set to 600 or even 400!
On NT check that the permissions are granted only to the user the service is running as!
1.     Check if the certificate has been imported correctly
sapgenpse get_my_name -v -n Issuer
The name of the Issuer should be: CN=SAProuter CA, OU=SAProuter, O=SAP, C=DE
2.     If this is not the case, delete the files cred_v2, local.pse and start over at Item 4. If the output still does not match please open a customer message in component XX-SER-NET-OSS stating the actions you have taken so far and the output of the commands
4.,7.,8. and 10.
Additional actions necessary before you can start saprouter
1.     The environment variable SNC_LIB needs to be set for the user account SAProuter is running under.
SNC_LIB has the form
UNIX      <path_to_libsecude>/<name_of_sapcrypto_library>
Windows NT, Windows 2000     <drive>:\<path_to_libsecude>\<name_of_sapcrypto_library>
2.     Check if the environment of the user running saprouter contains the environment variable SNC_LIB
UNIX     printenv
Windows NT     System environment variable
3.     start the saprouter with the following command line:
saprouter -r -S <port> -K "p:<Your Distingushed Name>"
-K tells the saprouter to start with loading the SNC library
the corresponding file ./saprouttab should contain at least the following entries
inbound connections MUST use SNC
KP "p:CN=sapserv2, OU=SAProuter, O=SAP, C=DE" <your_server1> <port_number>
repeat this for the servers and port_numbers you will need to allow,
please make sure that all explicit ports are inserted in front of a
generic entry '*' for port_number
outbound connections to <sapservX> will use SNC
KT "p:CN=sapserv2, OU=SAProuter, O=SAP, C=DE" <sapservX> <sapservX_inbound_port>
permission entries to check if connection is allowed at all
P <IP address of a local host> <IP address of sapserv2>
all other connections will be denied
D * * *
Example
For a SNC encrypted connection to the SAPRouter on sapserv2 (194.39.131.34), the saprouttab should contain the following entries:
SNC-connection from and to SAP
KT "p:CN=sapserv2, OU=SAProuter, O=SAP, C=DE" 194.39.131.34 *
SNC-connection from SAP to local R/3-System for Support
KP "p:CN=sapserv2, OU=SAProuter, O=SAP, C=DE" <R/3-Server> <R/3-Instance>
SNC-connection from SAP to local R/3-System for NetMeeting, if it is needed
KP "p:CN=sapserv2, OU=SAProuter, O=SAP, C=DE" <R/3-Server> 1503
SNC-connection from SAP to local R/3-System for saptelnet, if it is needed
KP "p:CN=sapserv2, OU=SAProuter, O=SAP, C=DE" <R/3-Server> 23
Access from the local Network to SAPNet - R/3 Frontend (OSS)
P <IP-addess of a local PC> 194.39.131.34 3299
deny all other connections

Pre Requisites for Implementing the CUE

Hi,
I have an IP Telephony set up with CME in 2 different branches.We need to implemet the AA in sites.
What are the pre requisites for hardware and license based that need to check before implementing the CUE.
one site having cisco 2911 router with Version 15.2(2)T3 and with interface ISM module is present which would like to configure for the AA.
second site having 2901 with Version 15.0(1r)M16 and with interface Embedded-Service-Engine0/0.
Attached is the Show tech support for each CME's .
Thanks in advance
Nithin Louis.

Hello
if there is no module installed you can completely ignore Embedded-Services-Engine as it won't be doing anything. Embedded Service Engine
Overview:-
Cisco Integrated Services Routers Generation 2 (Cisco ISRs G2) have dual core CPUs on the motherboard. The first core runs Cisco IOS software as Cisco Integrated Services Routers (ISRs) do; the second core, or the Embedded Service Engine, is capable of running Linux-based applications.
The following Cisco ISR G2 platforms support the Embedded Service Engine:
•Cisco 2911
•Cisco 2921
•Cisco 2951
•Cisco 3925
•Cisco 3945
Note:- As above 2901 not support embedded service engine . May be you got it on the CLI , because you run the same S/W version.Reference
https://supportforums.cisco.com/discussion/11184226/interface-embedded-service-engine00
*That is why i did not mention for Embededd service engine module supportedwith Cisco 2901, so kindly check. The above post Cisco document for compatibality.If you need to try , so try with minumum memory 1G as 2911
Memory required for 2911,2921 is 1G , 2951 is 1.5 G , 39XX is 2.5 G.My advise to you to go through ISM-SRE-300-K9 , and shut Embedded service engine .

Hello Venkatesan,
There isnt a T-Shirt sizing available for a Solution Manager system per scenario usage. You will have to use the sizing tool available on the url : http://service.sap.com/solutionmanager --> Check the section Starting with EHP1 and under the planning section you would find the sizing tool.
Once this tool is downloaded you can then add the scenarios that you would like to use and plan your system accordingly.
