CCMS implementation performance impact

Dears
I'm looking for information on the impact on performance of a CCMS implementation.
Impact on Solution Manager, impact on managed SAP systems. I opened a customer message but SAP comes back with there is no sizing documentation for ccms.
The purpose is to add a lot of managed SAP system into SAP Solution Manager and enable CCMS + IT Performance Reporting. I would like to know how much impact the RFC access causes.
If anyone has done a study on this or has information on this please share.
Kind regards
Tom

@Mauricio Yes I do understand the principal behind it. From a logical point of view it should improve performance but then again tests should have been run to prove the point.
For example: I'm involved in the pilot program for SAPJVM 4.1 and while SAP sais the performance should be the same or better but we all know SAP doesn't have every combination of OSDBSAP system running. It's the same principal, from a logical point of view it should be the same or better but one should do some performance tests to verify if it's the case.
@Augusto No problem on the misunderstanding, it shows my question wasn't that great and I should have provided more information
The point is that we have a lot of managed SAP systems to add and apparently SAP doesn't have that many customers that have a big number of managed SAP systems in the Solution Manager. The performance impact of CCMS implementation is neglictible if you only have some managed SAP systems. What is a 3% CPU rise in that case, shouldn't be a problem but now imagine you put in thirty times as much SAP systems then it can be become a problem if you don't foresee additional server resources.
A lot of those scenario's seem to have been tested with only a few managed SAP systems, doing a full landscape fetch through transaction SMSY takes a long time for example. I do know in Solution Manager 7.1 there is another component in between the SLD and SMSY which can synchronize content faster to avoid long runtime.
Another example was the landscape verification tool 1.0 which I reviewed in a blog. It didn't have a possibility to refresh single systems (I haven't checked latest version) but that is a problem if you have many managed SAP systems and you want to just check one. In the video demo's it flashes and it's very fast because there are only five managed SAP systems.
I'm looking forward to Solution Manager 7.1 but these kind of performance impacts should be known really. Doing a small implementation is no problem but customers are really interested in application lifecycle management and so on and are starting to generate demand for a lot of different scenario's. Sizing it is not that hard in small environment but once the environments become larger and a lot of managed SAP systems are involved the issue I see with CCMS for example rises and it becomes very hard to size properly. Perhaps it could be integrated into the quick sizer (number of managed SAP systems and enablement/use of certain scenarios).
I do know for some scenarios there is sizing documentation available, diagnostics being one of those.

  • Performance Impact for the Application when using ADFLogger

    Hi All,
    I am very new to ADFLogger and I am going to implement this in my Application. I go through Duncan Mill's acticles and got the basic understanding.
    I have some questions to be clear.
    Is there any Performance Impact when using ADFLogger to slower the Appllication.
    Is there any Best Practices to follow with ADFLogger to minimize the negative impact(if exists).
    Thanks
    Dk

    Well, add a call to a logger is a method call. So if you add a log message for every line of code, you'll see an impact.
    You can implement it in a way that you only write the log messages if the log level if set to a level which your logger writes (or lower). In this case the impact is like having an if statement, and a method call if the if statement returns true.
    After this theory here is my personal finding, as I use ADFLogger quite a lot. In production systems you turn the log lever to WARNING or higher so you will not see many log messages in the log. Only when a problem is reported you set the log level to a lower value to get more output.
    I normally use the 'check log level before logging a message' and the 'just print the message' combined. When I know that a message is printed very often, I first check the level. If I assume or know that a message is only logged seldom, I just log it.
    I personally have not seen a negative impact this way.

  • Performance Impact When Using SNC Communication

    Hello,
    Does anybody know if and how much performance impact there is if we use SNC for communication between the SAP Server and SAPGUI?
    I think there are two areas that may be impacted; Network and server CPU.
    For network load, I did find a part in "Front-End Network Requirements for SAP Business Solutions" document saying "overhead of roughly 350 bytes per user interaction step" but it does not specify the type of encryption.  I wonder if there is any other info on this?
    For CPU impact, how much overhead should I consider for sapgui access?
    I see no field for this in the quicksizer and I can't seem to find any white papers on this subject.
    Thank you in advance.

Let me know, if you need help finding it. My contact information is in my SDN business card.
    Just so Kan is clear - It is not legal to use the SAP cryptolib provided by SAP for SNC between SAP GUI and SAP servers, so if x.509 is the desired mechanism you need to purchase additional software from the company which Peter works for to provide SAP GUI SNC-based SSO. I think instead, Kan might be using the free SAP supplied SNC Kerberos library, which is why I asked him to confirm this in my last post. I doubt he is interested to buy any third party software.
    > As to the performance discussion: first of all, yes, there will be a small performance impact if SNC is used (no matter which type or implementation), but from our experience with many actual SNC implementations, I can state that this is practically not relevant. It is not noticeable by users. There were never any performance discussions with customers. See also SAP Note 1043694.
    I agree with this - the performance impact is not noticed by users, but the system managers who look after the servers where SAP is installed, and the team responsible for the network need to be aware of any differences (if any) when SNC is turned on and when SNC is turned off. I think this is why Kan is asking these questions, not because he is concerned about users noticing any difference when they logon to SAP.
    > Just a first quick comment on certain statements above: Tim's arguments for proving his overall statement are not conclusive from my perspective. Nor do I think his overall statement itself is correct.
    The facts I mentioned are well known facts, e.g. symmetric crypto is far better from performance point of view than asymmetric. I know the examples I have shown which I found when doing a quick google search were not conclusive, but they were shown as initial examples, not necessarily the best examples. This is why I specifically mentioned that if you search in google yourself you will see many more references where comparisons are done between Kerberos (e.g. symmatric) compared with PKI (e.g. asymmetric).
    > First of all, he only selects one aspect of performance - CPU impact of encryption algorithms.
    No, I didn't. Some of the examples I referred to also discuss other differences. I also mentioend other differences such as memory and what protection level is used when configuring SNC.
    > But for a true comparison, you'd have to look at all relevant aspects (latency, network overhead, ...).
    Yes, I agree. No doubts here.
    >Network performance overhead is usuallly worse with Kerberos than with PKI.
    This is not true. When SAP is using SNC, the GSS-API standard is used and so the only network communication involves SAP software sending a standard GSS token from the workstation to the SAP server, and this GSS token is often about the same size, regardless of which mechanism is used, so any network performance differences are not related to the mechanism, but more related to the complexity of the cryptography used on each end (mostly on the server side).
    >Second, you need to look at the specific usage scenario. For example, the first report referenced by Tim is an analysis about different Token Profile mechanism for WS Security, for one specific implementation. This does not allow to draw any conclusion for the SNC use case in general, and for sure not for a specific implemenation. It does not take the overhead for the encryption of the message content into account. Third, Tim associates PKI exclusively with asymmetric encryption. Yes, it is well known that asymmetric algorithms are slower than symmetric ones, but it is also well known that the encryption of the message content (by far the majority of the data) happens with symmetric encryption algorithms in the PKI scenario. With PKI-based SNC, you can even select a symmetric algorithm and use a more performant one that the ones that Kerberos prescribes.
    Kerberos works with many different symmetric algorithms as well, so mentioning that the alg is selectable is not relavent to any comparison.
    > To summarize, I will try and collect facts that will support the opposite point of view. From our practical experience, the performance overhead is not relevant, and criteria like consistency with SAPcryptolib, strength of security, ease of administration, choice of authentication and encryption mechanism, etc. are much more important.

  • Usage Tracking performance impact

    Hi all,
    I just started to implement the OBIEE usage tracking functionalities.
    Anyone implemented it and call share some experience on the performance impact with/without usage tracking enabled??
    Thanks
    BCHK

    If you use direct_insert option impact will be minimized. In general usage tracking captures report run activity and logs into table, so there is overhead on the system to insert to table or write to file. trade off is the information you get with usage tracking..
    hope this helps..

  • Index creation online - performance impact on database

    hi,
    I have oracle 11.1.0.7 database running on Linux as 3 node RAC.
    I have a huge table which has more than 255 columns and is about 400GB in size which is also highly fragmented because of constant DML activities.
    Questions:
    1. For now i am trying to create an index Online while the business applications are running.
    Will there be any performance impact on the database to create index Online on a single column of a table 'TBL' while applications are active against the same table? So basically my question will index creation on a object during DML operations on the same object have performance impact on the database? is there a major performance impact difference in the database in creating index online and not online?
    2. I tried to build an index on a column which has NULL value on this same table 'TBL' which has more than 255 columns and is about 400GB in size highly fragmented and has about 140 million rows.
    I requested the applications to be shutdown, but the index creation with parallel of 4 a least took more than 6 hours to complete.
    We have a Pre-Prod database which has the exported and imported copy of the Prod data. So the pre-Prod is a highly de-fragmented copy of the Prod.
    When i created the same index on the same column with NULL, it only took 15 minutes to complete.
    Not sure why on a highly fragmented copy of Prod it took more than 6 hours compared to highly defragmented copy of Pre-Prod where the index creation took only 15 minutes.
    Any thoughts would be helpful.
    Thanks.
    Phil.

    How are you measuring the "fragmentation" of the table ?
    Is the pre-prod database running single instance or RAC ?
    Did you collect any workload stats (AWR / Statspack) on the pre-prod and production systems while creating (or failing to create) the index ?
    Did you check whether the index creation ended up in-memory, single pass or multi pass in in the two environments ?
    The commonest explanation for this type of difference is two-fold:
    a) the older data needs a lot of delayed block cleanout, which results in a lot of random I/O to the undo tablespace - slowing down I/O generally
    b) the newer end of the table is subject to lots of change, so needs a lot of work relating to read-consistency - which also means I/O on the undo system
      --  UPDATED:  but you did say that you had stopped the application so this bit wouldn't have been relevant.
    On top of this, an online (re)build has to lock the table briefly at the start and end of the build, and in a busy system you can wait a long time for the locks to be acquired - and if the system has been busy while the build has been going on it can take quite a long time to apply the journal file to finish the index build.

  • Performance impact related to workbook

    Hi All,
    Please let me know the performance impact on workbooks if i insert 13 work sheets,
    How much performance impact will be there?
    If i insert all reports reports in 2 worksheets by splitting them,
    How much performance impact ll be there?
    Please let me know which one is better way
    Urgent!...
    Thanks,
    Sarau

    Hello Sarau,
    The performance is purely based on the Query selection, since that decide the number of records to be fetched.
    The more you filter the query the performance will be better.
    Since you are having many queries in a workbook, make sure that all have common variable screen.
    Thanks

This is not client code that can lay sole claim to most of the memory. It is server code and one of many server processes that need to share the available resources. So capitalism is fine on a client, but you need socialism on the server? {noformat} ;-) {noformat}
    Will it have any performance impact since all the data is stored in the memory.Interestingly yes. Usually crunching data in memory is better. In this case it may not be so. The memory used is the most expensive memory Oracle can use - the PGA. Private process memory. This means each process copy running that code, will need lots of memory.
    If you're not passing the data structures by reference, it means even bigger demands on memory as the data structure needs to be copied into the call stack and duplicated.
    The worse case scenario is that such code consumes so much free server memory, and make such huge demands on having that in pysical memory, it trashes memory management as the swap daemons are unable to keep up with the demand of swapping virtual memory pages into and out of memory. Most CPU time is spend by the swap daemons.
    I have seen servers crash due to this. I have seen a single PL/SQL process causing this.
    How can i measure the performance impact when the data grows ?Well, you need to look at the impact of your code on PGA memory. It is not SQL performance or I/O performance that is a factor - just how much private process memory your code needs in order to execute.

    The issue
       Performance :-   first time it is OK but for Consecutive calls the application is going down very visibly and after 4 iteration it hangs . When I look at the log I am getting this

  • EBS performance impact using it as a Data Source

    I have a quick question on EBS performance. If I set up the EBS Database as a data source for SSRS (SQL Server Reporting Services), would there be a performance impact on EBS, due to SSRS accessing EBS Data for reports generation? Now, I know there'll always be a hit depending on the volume of data being accessed. But, my question is, will it be significantly higher using an external reporting tool using an ODBC connection rather than native XML Publisher.

    Tough to answer without looking at data; my suggestion would be to have a test EBS environment setup, get permission from the vendors to run performance test without buying license - compare AWRs from both scenarios and then decide.
    Generally speaking, native XML publisher (BI Publisher) has less of database performance hit than external reporting tools using ODBC.

  • Performance Impact with OR concatenation / Inlist Iterator

    Hello guys,
    is there any performance impact with using OR concatenations or some IN-Lists?
    The function of both is the "same":
    1) Concatenation (OR-processing)
    SELECT * FROM emp WHERE mgr# = 1 OR job = ‘YOURS’;- Similar to query rewrite into 2 seperate queries
    - Which are then ‘concatenated’
    2) Inlist Iterator
    SELECT * FROM dept WHERE d# in (10,20,30);- Iteration over enumerated value-list
    - Every value executed seperately
    - Same as concatenation of 3 “OR-red” values
    So i want to know if there is any performance impact if using IN-Lists instead of OR concatenations.
    Thanks and Regards
    Stefan

    The note is very misleading and far from complete; but there is one critical point of difference that you need to observe. It's talking about using a tablescan to deal with an IN-list (and that's NOT "in-list iteration"), my comments start by saying "if there is a suitable indexed access path."
    The note, by the way, describes a transformation to a UNION ALL - clearly that would be inefficient if there were no indexed access path. (Given the choice between one tablescan and several consecutive tablescans, which option would you choose ?).
    The note, in effect, is just about a slightly more subtle version of "why isn't oracle using my index". For "shorter" lists you might get an indexed iteration, for "longer" lists you might get a tablescan.
    Remember, Metalink is not perfect; most of it is just written by ordinary people who learned about Oracle in the normal fashion.
    Quick example to demonstrate the difference between concatenation and iteration:
    drop table t1;
    create table t1 as
    select
         rownum     id,
         rownum     n1,
         rpad('x',100)     padding
    from
         all_objects
    where
         rownum <= 10000
    create index t1_i1 on t1(id);
    execute dbms_stats.gather_table_stats(user,'t1')
    set autotrace traceonly explain
    select
         /*+ use_concat(t1) */
         n1
    from
         t1
    where
         id in (10,20,30,40,50,60,70,80,90,100)
    set autotrace offThe execution plan I got from 8.1.7.4 was as follows - showing the transformation to a UNION ALL - this is concatenation and required 10 query block optimisations (which were all done three times):

  • Performance Impact of Using Sessions

    All,
    I have a general question regarding the performance impact of using Sessions
    within a Servlet. Specifically, I'm working with a group that wants to use
    the Session object to store customer contacts temporarily. The application
    is expected to service 2000 concurrent users, each maintaining no more then
    200 contacts each of which is about 1KB. The planned configuration is for a
    cluster of 10 instances of WLS. That said do we have any benchmark data
    that might assist in the session replication design, i.e. using in-memory
    across the cluster, using DBMS, etc.?
    Any information would be appreciated.

  • Performance impact on oracle 11g database by audit enable

    Hi All,
    Shall we enable audit on some siebel db tables like s_party s_contacts s_order s_quote s_org_ext
    We need to see who deleted account records from oracle tables manually
    Since auditing is not enabled.
    We have given delete privelege to to all users as required by Siebel application.
    So Is this good idea to get Auditing enabled on these selected tables or Is there any performance impact on database.
    Is it good idea to enable audit for these tables espacially in siebel
    SQL> select * from v$version;
    BANNER
    Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
    PL/SQL Release 11.2.0.1.0 - Production

    TNS for HPUX: Version 11.2.0.1.0 - Production
    NLSRTL Version 11.2.0.1.0 - Production

    Hello,
    Ok do it and generate AWR to see how the performance is getting impacted.remember auditing just some tables is not a big matter but auditing everything is the problem that is why fine grained auditing exist.please also remember to clean the audit records regularly because the auditing will be just a problem with the space in case you have many deletes which should not happen in your case.
    Kind regards
