SAP JDK - Best Practice

Hello Experts,
We are in process of upgrading our JDK from 17 to 22. We are wondering about the best practice. We checked SAP note 718901 and 731269.
After checking this note, we are wondering about best practice. How JDK should be installed?
We are using Windows 2003 with Oracle 10.2.0.2. When you install JDK it goes by default to C:\j2sdk1.4.2_17-x64. If we upgrade to 22, it creates new folder c:\j2sdk1.4.2_22-x64 and we need to reconfigure JAVA path and JAVA_HOME all places i.e. SDM, Config Tool and Visual Admin.
We are wondering if we install JDK to C:\JDK and during upgrade if we provide that path, we shouldn't have to change JAVA_HOME in all places.
Is it possible?
We tried making changes as per note 718901 with option 1 but it doesn't change in all places in config tool for JAVA_HOME. As per note 731269 both the JDK should be available for startup to sync file system and database. We are kind of confused.
Thanks in advance.
Thanks,
Miral.

First you have to change in instance profile and in environment variable. Then change in startup batch file of visual admin, config tool and SDM.

SAP ASE Best Practice latest update

Hello experts,
just wondering if somebody already reviewed thoroughly latest guide for best practices on SAP Sybase ASE?
I am talking about the document from note 1680803 - SYB: Migration to SAP Adaptive Server Enterprise - Best Practice (former note 1722359 - SYB: Running SAP applications on SAP ASE - Best Practice).
The guide for normal runtime operation was merged with the guide for migration, but there are some contradictory statements.
Apart from that the study case is again designed for server with huge memory and lot of CPU cores (so not so real case normally, I wonder who setup so often such huge servers...), I have found some inconsistencies.
E.g. in part "Reconfigure Engines and Parallel Processing", they talk about to limit ASE engines to 16, but the command configures 32.
alter thread pool syb_default_pool with thread count = 32, idle timeout = 2000
No change to the previous setup for migration. Is this just typo? I understand it should be 16, and then also number of network tasks for normal operation would be 4 (as mentioned in the beginning of guide that normally you set up 1 per 3-4 engnes). If this is not typo, then number of network tasks is wrong as it should be 8.
Also they introduced idle timeout, but only talking about ERP and possible lower value for Solman - does this mean that for BW you keep default value (which if I am not mistaken is 100)? As per ADM540 you should even decrease this timeout when SAP system is sharing server with database - I know that document is old, but is again contradictory, not saying that it is wrong, but not well explained.
If anybody checked new version of guide, please let me know, I think it is bit messed up and is bit difficult to distinguish what you should set up for migration case and what for normal operation case.
Thanks!

Matus

Actually, quite a few customers run with that many engines/memory.   In fact, it is difficult these days to even buy a server with less than 128GB of memory and 16 cores/32 threads.    Pretty much the only time we see less is when the install is in a VM.   Interestingly, we had comments from the first version suggesting the numbers were not realistic given the typical size of systems being deployed were much larger....    In addition, in my experience with customers on SAP systems, they were not aware of how much memory was necessary to really support medium to large systems based on the configurations they were attempting.
I am sorry that you feel some of the examples are contradictory. You are correct in pointing out that the text refers to 16 engines and the example configures 32....   So yes, for that specific example, it should have been 16.
Secondly, not having seen ADM540, but I think there is a bit of a problem if they suggest that.   I my opinion (and I have spent a lifetime tuning ASE), the idle timeout for ERP and BW should likely both be 1000+ and 2000 is not unreasonable.   The comment in ADM540 is likely due to if ASE and a NW CI are sharing the same cores - e.g. you have a 4 core box and ASE is running on 2 cores (we will ignore threads for this discussion) and you have 30 NW worker processes - which obviously will need to bump ASE off the cpu in order to run.   This may be fine in a test/dev or even a solution manager system, but bumping ASE off the core is NOT a good thing for a production system. In fact, I would encourage using numactl or similar to fence off the the cores used for ASE from NW worker processes if at all possible.   We have seen cases of overloaded NW installations with multiple CI instances with hundreds of worker processes each starving cpu away from ASE......sooo....I would tend to actually be a bit more than firm on suggesting that 100 is a very bad starting point.   Given the number of client side joins that SAP uses to avoid [DBMS proprietary] temp tables, it is critical that ASE's (or any DBMS) response time be minimized as much as possible.....having ASE yield the core practically as soon as it gets done processing one task (and puts it to sleep pending an IO) just really causes things to run slow.   Think of a typical query that returns 10 rows - say wide enough that each row fills 1 packet.   If the packet transmit time (and client ACK) takes more than 100 microseconds on CPU (almost a given for network interactions...as clock ticks are in nanoseconds and networking is minimally milliseconds - 1000 microseconds), ASE would yield the CPU every time it sent a packet.    When the client wanted the next packet, the OS would have to wake up the ASE process (an interrupted sleep) which is a nasty heavy weight operation.   Hence it is best for ASE to hang out on the CPU until reasonably sure that nothing more is going to happen very soon....and on current cpus...and having it run for 1-2ms (1000-2000 microseconds) shouldn't be a hardship.     If you created a separate thread pool for batch worker processes, then I could see maybe using a lower idle timeout such as 200 or 250......100 is just plain too low in my mind...it is like saying ASE is expecting an odd query every few seconds vs. a steady workload. Basically at that level, there had better be a task in the ASE job queue or one on the way on the network already, or that engine is going to sleep.
While I state that with regards to ADM540 itself, I have not seen the class (perhaps)...one customer did show me the notebook of a class (ASE Sys Admin) they went to and it was really targeted at non-SAP installations more than SAP installations - from a reality/experience aspect.   Part of the issue with the class the customer showed me was it borrowed liberally from the old SY classes as a starting point, but at the point the class was developed there was not a lot of experience with running SAP installations on ASE to really point out the fine tweaking areas such as idle timeout.
However, the document was really aimed primarily at Business Suite vs. BW systems or a Solution Manager install (which are much smaller) - there are a lot of other considerations for BW the guide doesn't get into - although some of the sizing is a better start than the defaults provided by SAPINST
The former runtime guide essentially was just merged in to the Post-Migration Steps section.
May do a quick refresh in the near-future (due to some recent experiences), so if you have other specific examples of the text and SQL not aligning - please let me know.

SAP to Non-SAP Integration best Practices

Hi Folks,
Recently I demonstrated to few of my managers the integration of our SAP ISU with a 3rd Party MDUS System via SAP PI. A question which was repeatedly asked is 'Why SAP PI'? Isn't there any other way to do it? They did mention BAPIs and doing things directly in ABAP but I couldn't really answer as to how weigh one on the other in this particular scenario.
I do know that there are standard ES Bundles for achieving integration with 3rd Party Systems via SAP PI, We can do the interface and message mappings but
is it possible to achieve this integration with the 3rd Party MDUS System without using PI?
3rd party MDUS can only integrate via its web Services so how would they get called?
Whats the trade-off in case of Performance, Development Cost?
I am looking for best practices, recommendations, trade-offs and possibilities. Your input is very much appreciated.

Adil Khalil

ECATT: SAP's Best Practice For eCATT

Hello All,
If multiple projects are handled on same server, then the master data keep on changing due to which the screen sequences of transactions may change and hence causing the failure of earlier automated eCATT scripts.
What is the best practice recommended by SAP for such situation both in long term as well as short term considering project deadlines?
Thanks & Regards.

Hi SAP Developer,
as far as I know there are no best practice guides for that from SAP.
But from common experience in automating testing one can propose:
For long term:
- organize your processes to be tested aligned as a number of szenarios; do a test case design also incorporating test data to be used; on that base derive (master) data that can be used in common by all szenarios; all other data should be used from single szenarios exclusively;
- use scripts also for creation of (master) data;
- try to use internal number assignment or create numbers in your eCATT script, so that every process run uses new new data accroding it's needs
- try to check customizing using CHETAB or BC Sets, stop the process if important settings are not there
The target of all this is to ensure, that neither customizing nor master data properties can raise different screen sequences.
Another option is to make your scripts more flexible regarding 'small' sequence changes like upcomming popups etc. when using SAPGUI command. This can be achieved by setting the 'Active' option of 'ProcessedScreen' elements.
If you use 'O' like optional, eCATT will only process the ProcessedScreen branch if the programm and dynpro number are matching the screen currently shown by SAP Gui.
Hope I could help a bit.
Best regards
Jens

SAP Adapter Best Practice Question for Migration of Channels

I have a best practice question on the SAP adapter when migrating an OSB project from one environment (DEV) to another (QA).
If my project includes an adapter channel that (e.g., Inbound SAP Proxy listening on a channel), how do I migrate that project to another environment if the channel in the target environment is different.
I tried using the search and replace mechanism in the sbconsole, but it doesn't find the channel name in the jca and wsdl files.
What is the recommended way to migrate from one environment to the other when the channel name changes?

SAP SCM and SAP APO: Best practices, tips and recommendations

Hi,
I have been gathering useful information about SAP SCM and SAP APO (e.g., advanced supply chain planning, master data and transaction data for advanced planning, demand planning, cross-plant planning, production planning and detailed scheduling, deployment, global available-to-promise (global ATP), CIF (core interface), SAP APO DP planning tools (macros, statistical forecasting, lifecycle planning, data realignment, data upload into the planning area, mass processing u2013 background jobs, process chains, aggregation and disaggregation), and PP/DS heuristics for production planning).
I am especially interested about best practices, tips and recommendations for using and developing SAP SCM and SAP APO. For example, [CIF Tips and Tricks Version 3.1.1|https://service.sap.com/form/sapnet?_FRAME=CONTAINER&_OBJECT=011000358700006480652001E] and [CIF Tips and Tricks Version 4.0|https://service.sap.com/form/sapnet?_FRAME=CONTAINER&_OBJECT=011000358700000596412005E] contain pretty useful knowledge about CIF.
If you know any useful best practices, tips and recommendations for using and developing SAP SCM and SAP APO, I would appreciate if you could share those assets with me.
Thanks in advance of your help.

Jarmo Tuominen

Hi Jarmo,
Apart from what DB has suggested. you should give a good reading on the following.
-Consulting Notes (use the application component filters in search notes)
-Collective Notes (similar to the one above)
-Release Notes
-Release Restrictions
-If $$ permit subscribe to www.scmexpertonline.com. Good perspective on concepts around SAP SCM.
-There are a couple of blogs (e.g. www.apolemia.com) .. but all lack breadth.. some topics in depth.
-"Articles" section on this site (not all are classified well.. see in ECCops, mfg, SCM, Logistics etc)
-Serivce.sap.com- check the solution details overview in knowledge exchange tab. There are product presentations and collaterals for every release. Good breadth but no depth.
-Building Blocks - available for all application areas. This is limited to vanilla configuration of just making a process work and nothing more than that.
-Get the book "Sales and Operations Planning with SAP APO" by SAP Press. Its got plenty of easy to follow stuff, good perspective and lots of screen shots to make life easier.
-help.sap.com the last thing that most refer after all "handy" options (incl. this forum) are exhausted. Nevertheless, this is the superset of all "secondary" documents. But the maze of hyperlinks that start at APO might lead you to something like xml schema.
Key Tip: Appreciate that SAP SCM is largely driven by connected execution systems (SAP ECC/ERP). So the best place to start with should be a good overview of ERP OPS solution overview, at least at the significant level of depth.). Check this document at sdn wiki "ERP ops architecture overview".
I have some good collection of documents though many i havent read myself. If you need them let me know.

SAP SD best practices for software companies

Dear All
Does anybody have Best practices building blocks for Software companies? I need to know how SD mapped in software companies? Especially in consulting a resource or sending a resource to client site? How does this can be mapped? Can anbody explain?
I couldnt find any best practices available in help.sap.com
Please advise..
Regards
Deepu Pillai

Dear Goud
Thank you.
But here the requirement is a resource can be billed based on time sheets. So to create a value contract & based on contract create a sales order may not satisfy the process.
But my concern is a person is billled based on times sheets, how the cost of the person fetched in the sales order?

SAP RAR - Best Practice ECC,CRM and BW systems

Hi All
i have the requirement to configure RAR for the systems ECC,CRM and BW systems . Each system has only one client . whats the best practice regarding using the rules against each system . i am assuming the rules will be the same irrespective of the system but when i see the names of the initial files , they are system specific . can anybody elloborate around this . thanks
Regards
Prasad

Prasad,
To build on Chinmaya's explanation, make sure you use a logical system for CRM, BI, and ECC for the basis portion of the rule set (and only the basis portion). This will keep you from duplicating your rules to meet your basis requirements. The other rules should be attributed to the individual systems (or additional logical systems if including mult landscapes, ex. Dev, QA, and Prod ECC merged into one ECC logical system).

SAP Adapter Best Practice Question for Deployment to Clustered Environment

I have a best practices question on the iway Adapters around deployment into a clustered environment.
According to the documentation, you are supposed to run the installer on both nodes in the cluster but configure on just the first node. See below:
Install Oracle Application Adapters 11g Release 1 (11.1.1.3.0) on both machines.
Configure a J2CA configuration as a database repository on the first machine.
Perform the required changes to the ra.xml and weblogic-ra.xml files before deployment.
This makes sense to me because once you deploy the adapter rar in the next step it the appropriate rar will get staged and deployed on both nodes in the cluster.
What is the best practice for the 3rdParty adapter directory on the second node? The installer lays it down with the adapter rar and all. Since we only configure the adapter on node 1, the directory on node 2 will remain with the default installation files/values not the configured ones. Is it best practice to copy node 1's 3rdParty directory to node 2 once configured? If we leave node 2 with the default files/values, I suspect this will lead to confusion to someone later on who is troubleshooting because it will appear it was never configured correctly.
What do folks typically do in this situation? Obviously everything works to leave it as is, but it seems strange to have the two nodes differ.

What is the version of operating system. If you are any OS version lower than Windows 2012 then you need to add one more voter for quorum.

SAP Rules Best Practices - transaction MFBF

Hello,
Can you share how do you classify MFBF (Backflush in Repetitive Manufacturing)? My process owner claims it allows user to Scrap materials improperly and should be controlled.
It is not in any function in SAP suggested rules, in my experience that normally means that the transaction call other that are classified, and most of time SE97 is used to control the called transaction authorization behavior. Anyone knows if this is the case too?
Thanks
