Tuning facilities available?

Hi there'
What are the plans for introducing tuning facilities in Raptor - and would it more than "just" explain plan/TKprof ?
Regards, Henrik

The 1.1 release will have a focus on tuning.

New Book on SAP BW Performance Tuning

Hi All,
Just thought of sharing this info on SDN...
A new book on SAP BW Performance Tuning is available...
http://www.erpguides.com/books/bwperformance.htm
Shreekant W Shiralkar & Bharat Patel have authored a book on SAP BW Performance Tuning. The book is based on their real life experiences on improving the system performance using various features/techniques/ideas.
I am aware that the The book covers many how-to procedures with screen shots for helping the reader to implement the performance improvement and benefit immediately. It would be interesting to read this book as a compilation of practical experiences on performance tuning .
Cheers,
Amol

Hi,
Read Data warehousing books written by Ralph Kimball or Bill Inmon in order to familiarize yourself with the basic concepts of data warehousing. This is the foundation of the entire thing.
Follow the SAP training materials on BW Data Warehousing, BW Reporting and BW Modeling. There are several books that can help you a lot when getting started. check this link
[http://www.amazon.com/SAP-BW-Book-List/lm/RRWM7R55RBEXQ/ref=cm_lmt_srch_f_2_rsrsrs2/103-7157721-8001426]
After you have a solid BW knowledge, start to review the help.sap.com site.
Hope this helps,

Disabling Diagnostics+Tuning packs in ASM

Am running ASM (11.1.0.6) on several Linux RHES 4.5 boxes and can't seem to disable the Diagnostics and Tuning options on the ASM instance, which I really should do as we're not licensed for it.
I did not explicitly accept use of the packs, for either the db instance, the host or the ASM instance (as you used to have to do on starting EM for the very first time after instance creation in 10g), however the performance options were available after instance creation and the 'Pack Access Agreed' column was ticked for the db instance, the host and the ASM instance.
I have been able to reset the options for the database and the host, and can also deselect those options for the ASM instance from the Management Pack Access page. This then greys out the displays asssociated with the packs in the ASM EM page.
However every time I log out, log back in and go back to the ASM section of Enterprise Manager, the diagnostic and tuning pack availability boxes are selected and the performance tab is no longer greyed out.
Connecting as sysasm via the command line shows the parameter control_management_pack_access as being set to DIAGNOSTICS+TUNING, however attempting to update that parameter directly via alter system set..... returns the error: ORA-15021 parameter not valid in ASM.
I can manually avoid using this functionality, but this isn't ideal and I'd hate to fall foul of Oracle licensing.
Can anyone shed any light on this?
Thanks,
Gavin

Hi Gavin ,
I am not sure if this parameter is applicable for ASM.
Please check if below helps :

Not finding facilities in Numbers

I do not find some facilities existing in Excel:
-replace values or correct formulas within selected cells and not the entire spreadsheet
-Freeze titels over more than 5 rows and simply by dragging a handle
-define links between spreadsheets in order to import data
Are those facilities available in Iwork?
Many thanks

I do not believe that allowing more than 5 rows is a great software intervention, and i do not understand why this limitation is existing.
Perhaps because you don't know the internals of the application.
It's funny to see how many guys feel that they are more knowledgeable than Apple Engineers.

TOR and availability

Hi all,
which will happen first TOR and availability check

dear lsayah
once you enter the qty in the order system will send the requirement to procurement TOR ( transfer of requirement ) then availability check will happen
that perticular material for perticular qty on perticular date will available or not
the details notes on TOR and Availability check
TOR AND AVAILANBILITY CHECK
To confirm the quantities for a particular line item in the sales order on particular day system carried out transfer of requirements (TOR) & AVAILABILITY check, so has to confirm the quantity on particular day as system should know what are there requirement of the sale order and delivery with MRP then system carries out availability check function, to confirm the quantity on particular day. Depending upon the IMG setting system carries out availability check function based on 3 methods:
A) Availability Check with ATP logic or against planning:
In ATP logic systems ATP Qty while carrying out availability check function for
Particular line item (ATP qty=warehouse stock +planned receipts planned issues)
Planned Receipts: EX: - purchase requisitions, purchase orders, stock in transfer stock at inspection etc.
Planned Issues: - EX: - open sales order & open delivers
B) Availability check against product allocation:
Availability check can be carried out against product allocations in which system automatically restrict the user to confirm the quantity beyond reserved quantities per particular customer. EX:- Availability qty =100, existing orders=10,then system automatically distributes to items evenly to the sales order.
C) Rule based Availability check:
Rule based availability check can be carried out based on the business transaction.
EX: - For normal sales order system has to carry out availability check for special sales order ex: - cash sales and rush order systems need not to be carry out availability check,
In rule based availability check system in which system carried out Global availability to promise in all plants. In this check system transfers the requirements to APO system where GATP takes place and the result of the availability check transferred to R/3 system. This process takes place with the transaction code CIF(central inter face) inR/3.After carrying out availability check function system proposes(by using ATP logic) default values of ATP check result to the user in a dialog box, in which system gives the choice to the user to take the decision in contest of insufficient stock.
a) One time delivery:
If the user chooses one time delivery and the order Quantity is 100 units system confirms 50 units then systems automatically confirms as a zero. If the user saves the document with the zero confirm qty then system   trace the sales order as aback order (V_RA), which can be confirmed later by RESCHEDULLING (V_V2).
b) Complete Delivery:
If order Qty=100, Availability stock = 50, system says that remaining can be given after one week. Then if the user selects this option then system push up existing confirmed qty to after one week and the total qty can be confirmed after one week only.
c) Delivery Proposal:
If order qty=100, system confirms 50, and remaining 50 can be confirmed after one week. If the user chooses this option then system confirms 50 Qty today allows the user to delivery 50 quantities today remaining 50 can be delivered after one week.
CONFIGURATION SETTINGS FOR TOR:
Define Requirement Class:
Path: Img  S&D  Basic functions  Availability Check & Transfer of requirements  Transfer of requirements    Define Requirement classes
Requirement classes control MRP, Requirement consumption, strategy, relevance for planned. It specifics whether the availability check & TOR to be Called out for transactions. Ex: Sales Order
It determines whether requirements relevant for MRP or not, the allocation indicator from the sales view which controls the settlement of customers requirements with planned independent requirements. It determines the item b to be settled as an availability heck. Assignment, the settlement profiles the results analysis key. The TOR and Availability check functions are globally controlled using the requirement class for all the Sales documents. The values from the Requirements class are transferred to scheduled the of the sales documents class are transferred to scheduled the of the sales document default values and can be over written there.
Define Requirements Classes:
Requirement class defines whether the system has to carry out availability check based on the STP Qty. Ex:
Define Requirement Types:
Here we define requirement type, Ex: and Assign to Requirement class that we defined in the promote step.
Determination of Requirement types using Transaction:
Requirement type is going to be determined for sales document by following a search strategy. .
First System checks strategy group in MRP3 view if it trend requirement type then system takes from it, otherwise.
It will go to MRP group in MRP1 view, otherwise
It will check to Material type, otherwise
It will go to item Category + MRP type, otherwise
It will go to Item category only, otherwise
Finally system determines the transaction b not relevant for TOR & Availability check.
Choose Item category TAN+MRP type PD=Requirement type =0
Define Procedure for each schedule the category:
Here we define respective schedule the category of the sales documents, whether an availability check and TOR should be carried out. This setting is relevant for sales documents only. It is fine tuning of availability check for sales documents TOR & Availability check function    can be activated at sales order level those are proposed in to schedule line category level. If u wants to deactivate TOR availability check function at schedule the category level and want to deactivate at requirement class level it b impossible.
Ex: If u wants to check availability w/o transferring the requirement we can use it.
Choose schedule line category CP & Activate Availability check, requirement & Product Allocation
Block Quantity confirmation in delivery Blocks:-
When we transfer requirements to MRP then confirmed quantities is also reserved for confirmed sales documents, if transaction is blocked for delivery the reserved quantities are also blocked so that the conformed quantities cannot be used by any other purpose. So has to avoid this situation we can block the transfer of requirements(TOR) for delivery blocks, in this case requirements transferred to MRP but will not be reserved, that will be cleared once we save the documents then system shows confirmed qty as zero.
When we remove the delivery block then system automatically carries out availability check & confirms the qty.
A) Deliveries: Blocking region for sales Area:
     Here we define blocking regions for TOR ex:-credit limits
B) Reasons for scope of delivery blocks: TOR. Block:
Ex: - 01 credit limits-check confirmation block.
Maintain Requirements for TOR:-
Here we can define our own requirement with the help of ABAPer for TOR
Ex: - a) 102- prevent reservation in the event of credit block
       b) 102-purchase requisitions.
System doesnt create purchase requisitions for sales order line items if it has a credit limit.
Availability check:
Configuration setting:-
Availability check with ATP logic or against planning:-
Define checking group:
Checking group define what kind of requirement record system use to create when sales order & deliveries are processed for this material. We can create 2 kinds of requirements records
Individual requirement records: that means system creates requirement record for each S&D document.
Summarized requirement Records: That means system creates requirement records under certain condition in the material master record. There are 2 type of summarized requirement record:
Summarized requirement records for each day.
Summarized requirement records for each week
Define checking Action;
Here we define 01- daily requirement      -B                                    02- Individual requirements -A
Where b-total record per day
     A-single record per day
B) Define material Block for other users:
When 2 users tries to confirm the quantities for the sales order for same material at a time system will be confused to confirm the quantities both sales orders. So has to avoid this kind of situation we can block the materials from confirming the quantities for 2 users at a check, check block
C) Define checking group default values:
Checking group is going to be determined depending upon the material type & plant.
-Go to new entries, specify material type, ex;-FERT
& plant = checking group of availability check: 02
D) Carry out for Availability check:
Here we define checking rule for the Availability check & allocate them to the checking group. The checking rules specify the scope of the availability check. For a respective transaction, means which planned receipts & planned issues systems has to taken into consideration and also it determines whether system has to take RLT into consideration.
Action:
*Select checking group of availability check-02, checking rule=01
*Go to details icon, & check which planned receipts & planned issues system has taken into consideration for availability check
*save it, exit.
E) Define procedure by Requirement class:
Here we define requirement class whether on availability check & TOR should be carried out the setting that we carries out at requirement class level they are at global level. There settings automatically copied into define from of requirement class and vice versa.
Action:
*Choose requirement class: 041 & check availability check & TOR (requirement)
F) Define procedure for each schedule line category:
Here we carry out fine tuning setting for availability check at schedule line category level. Here we define whether system has to carry out Availability check for particular transaction.
Ex:- if we want to implement a availability check w/o TOR for a particular transaction. According to settings at requirement class level TOR & availability check function activate & those setting will be copied into the schedule time category by default, so that at schedule line category level we deactivated TOR
G) Determine procedure for each Delivery Item category:
Here we switch on or switch off availability check functions of a delivery item category
*choose item category TAN. & specify the appropriate value.
H) Checking group for updating back orders:
Here we assign checking group to a plant that rule specifies for individual application, according to which the availability check is carried out;
I) Define Default settings:
Here we define the result of the availability check.
*Choose your sales Area, & check fixed dates& Qty options & specify D or E
Where: D- Dialog box in the case of shortages (one time delivery)
E- Dialog box in the shortages (delivery proposal).

Tuning worksheet for system9 Essbase

Hi All,
Does anyone have a System9 version of the Tuning Worksheet available in Pre-System9 used to evaluate database size/growth?
I have tried using the old one but it is not accurate for System9.
Thanks for your help.
Seb
[email protected]

It is not an error I have really seen though this line is the important one
com.hyperion.planning.HspRuntimeException: Error occured during Essbase RTC initialization.
Which reads to me the planning web application has problems starting up the essbase runtime client.
This would make me think there is either a problem when planning was deployed or maybe an issue with environment variables.
If you are on windows I take it you have rebooted the machine since you installed planning.
If this is a new installation and configuration of planning it may be worth trying to install again if you don't get any further.
Cheers

Seeks Advise on Selecting the Oracle DB Tuning Tools

I could not find the most relevant discussion group, so I picked this one since it seemed the closest. Please ingore this if you find it out of place here.
We would like to hear about your recommendations and experiences with various DB tuning tools available in the market. There is already a product from Oracle, Oracle Tuning, Diagnostics, and Change Management Packs, which is bundled with the Enterprise Manager V21. Are you aware of similar rival products? And how would you rank them?
We are looking to pick a product and we highly appreciate to receive you feedback.
Thanks you very much in advance.

One of the products I have very good experiences with is Precise SQL.
You can analyze certain performance issues (I/O, memory, etc) up to statement level. Another nice feature is that it can predict, based on a performance warehouse, how certain changes will affect the performance on your database even before you apply them.
What I really liked the most about this product is the minimum impact it has on your database. It doen't use the Oracle v$views, but it reads the SGA without using Oracle.

IOS XR OSPF subsecond timer vs BFD

Dear all,
We recently got problem with subsecond OSPF timer on CRS.
On previously, we can configure OSPF hello timer min dead-interval 3 on 7606 router, which mean OSPF hello is at 333 ms.
Unfortunatelly, CRS cannot be configured with 333 ms for hello timer.
And theres some of our TAC case with result that we need configure BFD.
If we configure BFD on top of OSPF, is it recommended ?
Is we got the same behaviour like having 333ms on OSPF, as expected when we configure BFD on top of OSPF at CRS ?
And our network has different router like ASR9000 series, 7600 series router, ME6524 series. Is all has the same behaviour when we config the same BFD configuration and parameter ?
Is it configuring the BFD on routing protocol is recomended ? replacing the sub-second timer configuration ?
Thanks,
Budi L

Hi,
In a general sense, For a network with very low convergence requirements (sub second), choosing the 'right' methods to achieve the optimum network convergence is a long excercise that highly depends on network design and Hardware/Software features. So as a start, make sure you know what your current software and HW can and can not support. Then look at what will be the outcome of combining different fast convergence and High availability features together.
So you have 3x blocks of different ways to enhance fast convergence and high availability:
1- LDP-IGP sync: be careful with LDP-IGP sync as XR has a different behavior than IOS (IGP adj is always build so there is no concept of holddown timer).
2- OSPF process tuning : LSA and SPF throttle tuning
3- Link failure detection tuning : BFD
I would start with LDP-IGP sync and tuning the link failure detection can be done after or before the OSPF protocol tuning.
Example: Making sure that Link failure detection mechanism is compatible with your HA configuration. For example BFD is not handled in Hw on 7600 so you can't use it if you also want SSO/NSF on this box as well. The neighbor will switch to a backup path before OSPF GR has a chance to start.
You have to plan for more 2 different kind of convergence events here, a down convergence event (BFD and protocol timers detect this), and an up convergence event (not timer based, service establish based on what facilities are available). The state between the start of the up convergence and fully converged is a transient state where multiple things start to happen depending on the facilities available (first interface up, then IGP, maybe PIM, maybe BGP, etc). At scale, this state is often very non-deterministic, rarely happens in the same order twice, and requires some amount of system analysis to make sure there are enough resources available to re-establish all the different services without the risk of flapping anything.
The more processes you add to the router (OSPF, BGP, PIM, and now BFD) the more critical it is to pay attention to how much time and resources each process requires. Reducing protocol timers can exaggerate the conditions in the transient state, so there are tradeoffs for having low convergence vs. scale/performance. For instance if BGP is not fully reconverged and a neighbor flaps because the CPU is busy, the whole process may have to start all over again and there is potential that the router may never fully recover if that scenario repeats.
BFD and IGP timers are mutually exclusive, It is always recommended to turn BFD on with IGP. Be sure not to tune OSPF too aggressive. Also to keep in mind that BFD is not SSO aware (Think IOS vs XR), so when there is a SUP fail over, BFD will observe microflaps hence you will see some packet loss. That's why you have to tune the values to an optimum level e.g. for a MAN 200-300ms interval for BFD control packets should be fine but you have to test it.

Open Letter to Adobe

Dear Adobe
In spring. I have been on creative cloud subscription for 2 years. for 2 years I have dealt with multiple sign ins before I can use the cloud. and several times a month the main updater gets updates requiring a sign in. I have to sign into on the web then sign into the forum then sign in to customer service. I have to sign into chat. I had to sign in 3 times to get to this forum. I respect that adobe needs to stop piracy, it costs them money. But the method they use to curtail piracy causes me (the one who pays) to lose time and money. Ive spoke to adobe for 2 years and nothing seems to change. so I will. I will not be renewing for a third year. Adobe will not miss me, but I will not miss Adobes anti piracy nag ware pop ups.
All the best
Steven

Mr. Weatherford,
Please understand that you are posting on a User to User forum that is not officially monitored by Adobe.
If you would like your ideas to be considered, you might be better off addressing them directly to Adobe company executives and/or using the facilities available on Adobe's website for submitting feature requests and/or reporting bugs.
