What is private mode? When does user switch to user mode?

Private mode is a mode where the heap data is getting exclusively allocated by the user and is no more shared across the system. This happens when your extended memory is exhausted.

What is osp$ mean? What if user is given with this authorisation?

OPS$ is the mechanism the <SID>adm users uses to connect to the database .

Why do you use DDIC user not SAP* for Support Packs and SPam?

Do _NOT_ use neither DDIC nor SAP* for applying support packages. Copy DDIC to a separate user and use that user to apply them.

Can you kill a Job?

Yes – SM37 – select – kill

If you have a long running Job, how do you analyse?

Use transaction SE30.

How to uncar car/sar files in a single shot?

on Unix:
$ for i in *.SAR; do SAPCAR -xvf $i; done

When we should use Transactional RFC ?

A “transactional RFC” means, that either both parties agree that the data was correctly transfered – or not. There is no “half data transfer”.

What is the use of Trusted system. I know that there is no need of UID and PWD to communicate with partner system. In what situation it is good to go for Trusted system ?

E. g. if you have an R/3 system and a BW system and don’t want to maintain passwords. Same goes for CRM and a lot of other systems/applications.

Let me know if my understanding below is correct:
1) By default the RFC destination is synchronous
2) Asynchronous RFC is used incase if the system initiated the RFC call no need to wait for the response before it proceeds to something else.

Yes – that’s right.

But keep in mind, that it’s not only a technical issue whether to switch to asynchronous. The application must also be able to handle that correctly.

Which table contains the details related to Q defined in SPAM? Is there a way to revert back the Q defined? If yes, How?

There is a “delete” button when you define the queue. If you already started the import it’s no more possible since the system will become inconsistent.

What is a developer key? and how to generate a developer key?

The developer key is a combination of you installation number, your license key (that you get from http://service.sap.com/licensekey) and the user name. You need this for each person that will make changes (Dictionary or programs) in the system.

What is XI3.0 ? EXPLAIN XI = Exchange Infrastructure – Part of Netweaver 2004.

SAP Exchange Infrastructure (SAP XI) is SAP’s enterprise application integration (EAI) software, a component of the NetWeaver product group used to facilitate the exchange of information among a company’s internal software and systems and those of external parties. Like other NetWeaver components, SAP XI is compatible with software products of other
companies.

SAP calls XI an integration broker because it mediates between entities with varying requirements in terms of connectivity, format, and protocols. According to SAP, XI reduces integration costs by providing a common repository for interfaces. The central component of SAP XI is the SAP Integration Server, which facilitates interaction between diverse operating systems and applications across internal and external networked computer systems.

How to see when were the optimizer stats last time run? We are using win2k, oracle 9, sapr346c.

Assumed DB=Oracle

Select any table lets take MARA here but you should do the same for MSEG and few others to see whether the dates match or not.Run the following command on the command prompt:-

select last_analyzed from dba_tables where table_name like ‘%MARA%’;

This gives you a straight answer .Else you can always fish around in DB14 for seeing when the optimzer stats were updated.

What is the use of profile parameter ztta/roll_area?

The value specifies the size of the roll area in bytes. The roll area is one of several memory areas, which satisfies the user requests of user programs. For technical reasons, however, the first 250 KB or so of a user context are always stored in the roll area, further data
– up to the roll area limit ztta/roll_first,
– in the extended memory, up to the limit ztta/roll_extension or if extended memory is exhausted, then
– again in the roll area, until the roll area is full, then
– in the local process area, up to the limit abap/heap_area_dia or abap/heap_area_total or until the address space or the
swap space is exhausted.

Followed by termination with errors like STORAGE_PARAMETERS_WRONG_SET an error code, that points to memory bottleneck Minimum data transfer with context change; however, the increase helps to avoid problems (address space, swap space, operating system paging).

What is R/3? and what is basis version?

SAP Basis:

– Provides the runtime environment for all SAP applications
– Optimally embeds the application in the system environment
– Defines a stable architecture framework for system enhancements
– Contains the tools for administering the entire system
– Allows the distribution of resources and system components
– Provides interfaces for decentralized system parts and external products.

An R/3 instance is a group of R/3 services that are started and stopped as a unit (by an R/3 dispatcher) and have a common instance profile. The name of an R/3 instance is composed of letters standing for the relevant services, and an instance number which is unique for each computer. The services may be D, V, E, B, M, G, or S, which respectively stand for dialogue, update, enqueue, background, message, gateway, and spool services.

I would like to know the version or name of SAP that is implemented in real time?

This is a very generic question and really depends on what you are implementing (modules).

The history of the “R/3” is

3.0D Basis 300
3.0E Basis 300
3.0F Basis 300
3.1H Basis 310
3.1I Basis 310
4.0B Basis 400
4.5B Basis 450
4.6C Basis 460
4.71 Basis 6.20
4.72 Basis 6.20
5.00 Basis 6.40 (ECC 5.0 – Enterprise Core components)
6.00 Basis 7.00 (ECC 6.0) – actually in RampUp

All of those have increased business functionality and interfaces to other systems (CRM, BW etc.)

What is mysap?

It’s a term for all the systems that in a contract (e. g. a MySAP business suite consist of ERP2005, CRM2005, SRM2005).

What is the systems configuration required to implement SAP.. i.e for production,development and QAS servers the hard disk space, RAM, Processor

This also depends on what your are implementing, how many users will work on the system, how many records in what area are created etc.

We need a BIG database system and an even bigger application server for ~ 900 users and 12 languages.

What is ASAP?

It’s an old term for an implementation strategy. Blueprint -> prototype -> goLive (if you want to say it in one sentence).

How should I set priority for Printing say like user, teamlead, project manager?

There’s nothing like “priority” settings for spool processes. Just define more (profile parameter rdisp/wp_no_spool) processes so people don’t need to wait.

Using Tc SGEN I have generated 74% job and later I have terminated the job. I wish to start generating from where it stopped I have refreshed but to no chance nothing was done. How should I further proceed so as to complete the remaining job..

Start SGEN again and select the same you have selected before. It will popup and ask if you want to start from scratch or generate the just the remaining.

Ask him/her to describe how SAP handles Memory Management?

ST02 / ST03 In general via table buffers, you could go into the whole Work Process, roll in, roll out, heap (private) memory, etc. however just as a Unix or DBA admin would know, is you look this up when needed for the exact specifics.

Ask him/her to describe where they would look at the buffer statistics, and what steps they would use to adjust them?

ST02, RZ10

Ask him/her to describe how to setup a printer in SAP or where they would look to research why a user/users can not print?

SPAD, SP01, SM50, SU01
