Can anybody recommend useful performance and tuning books. I plan to take the 12c perf tune beta on March 21st

Can anybody recommend any useful performance and tuning books.
I should probably limit my search to 11g or higher.
I am starting to prep for the 12c perf and tuning beta I have scheduled on March 21st.
Thanks Roger

Hi,
I will review your review.
I do see this Oracle 12c book at Amazon written over a year ago.
Its not a certificaiton book.
I also did take the course at Oracle for 11g performance and tuning.

Performance and Stability Problem with PE9

I just upgraded my computer to a Core i5 with 8G of memory and everything is running much faster. But my NEW PE9 just run very slow. Some of the simple tasks take 10-30 second to complete. Even Windows 7 will often come out to ask if I want to wait for PE9 to wake up or kill the process. When I want to change the size of a video clip, it just doesn't work at all due to performance. It will take PE9 20-30 seconds to resize the video clip. Without some realtime feedback of the size, it is impossible to do the resizing and this is a very fundamental operation. PE9 often crash or seize up as well, I didn't have any of these problem with PE3.0. I upgraded to PE9 simply because my PE3.0 for WIndows XP is not comletely compatible with Windows 7 (some of the text displace does not show up).
Do anyone else have issue with performance and stability?

BW Back end
Some Tips -
1)Identify long-running extraction processes on the source system. Extraction processes are performed by several extraction jobs running on the source system. The run-time of these jobs affects the performance. Use transaction code SM37 Background Processing Job Management to analyze the run-times of these jobs. If the run-time of data collection jobs lasts for several hours, schedule these jobs to run more frequently. This way, less data is written into update tables for each run and extraction performance increases.
2)Identify high run-times for ABAP code, especially for user exits. The quality of any custom ABAP programs used in data extraction affects the extraction performance. Use transaction code SE30 ABAP/4 Run-time Analysis and then run the analysis for the transaction code RSA3 Extractor Checker. The system then records the activities of the extraction program so you can review them to identify time-consuming activities. Eliminate those long-running activities or substitute them with alternative program logic.
3)Identify expensive SQL statements. If database run-time is high for extraction jobs, use transaction code ST05 Performance Trace. On this screen, select ALEREMOTE user and then select SQL trace to record the SQL statements. Identify the time-consuming sections from the results. If the data-selection times are high on a particular SQL statement, index the DataSource tables to increase the performance of selection (see no. 6 below). While using ST05, make sure that no other extraction job is running with ALEREMOTE user.
4)Balance loads by distributing processes onto different servers if possible. If your site uses more than one BW application server, distribute the extraction processes to different servers using transaction code SM59 Maintain RFC Destination. Load balancing is possible only if the extraction program allows the option
5)Set optimum parameters for data-packet size. Packet size affects the number of data requests to the database. Set the data-packet size to optimum values for an efficient data-extraction mechanism. To find the optimum value, start with a packet size in the range of 50,000 to 100,000 and gradually increase it. At some point, you will reach the threshold at which increasing packet size further does not provide any performance increase. To set the packet size, use transaction code SBIW BW IMG Menu on the source system. To set the data load parameters for flat-file uploads, use transaction code RSCUSTV6 in BW.
6)Build indexes on DataSource tables based on selection criteria. Indexing DataSource tables improves the extraction performance, because it reduces the read times of those tables.
7)Execute collection jobs in parallel. Like the Business Content extractors, generic extractors have a number of collection jobs to retrieve relevant data from DataSource tables. Scheduling these collection jobs to run in parallel reduces the total extraction time, and they can be scheduled via transaction code SM37 in the source system.
8). Break up your data selections for InfoPackages and schedule the portions to run in parallel. This parallel upload mechanism sends different portions of the data to BW at the same time, and as a result the total upload time is reduced. You can schedule InfoPackages in the Administrator Workbench.
You can upload data from a data target (InfoCube and ODS) to another data target within the BW system. While uploading, you can schedule more than one InfoPackage with different selection options in each one. For example, fiscal year or fiscal year period can be used as selection options. Avoid using parallel uploads for high volumes of data if hardware resources are constrained. Each InfoPacket uses one background process (if scheduled to run in the background) or dialog process (if scheduled to run online) of the application server, and too many processes could overwhelm a slow server.
9). Building secondary indexes on the tables for the selection fields optimizes these tables for reading, reducing extraction time. If your selection fields are not key fields on the table, primary indexes are not much of a help when accessing data. In this case it is better to create secondary indexes with selection fields on the associated table using ABAP Dictionary to improve better selection performance.
10)Analyze upload times to the PSA and identify long-running uploads. When you extract the data using PSA method, data is written into PSA tables in the BW system. If your data is on the order of tens of millions, consider partitioning these PSA tables for better performance, but pay attention to the partition sizes. Partitioning PSA tables improves data-load performance because it's faster to insert data into smaller database tables. Partitioning also provides increased performance for maintenance of PSA tables for example, you can delete a portion of data faster. You can set the size of each partition in the PSA parameters screen, in transaction code SPRO or RSCUSTV6, so that BW creates a new partition automatically when a threshold value is reached.
11)Debug any routines in the transfer and update rules and eliminate single selects from the routines. Using single selects in custom ABAP routines for selecting data from database tables reduces performance considerably. It is better to use buffers and array operations. When you use buffers or array operations, the system reads data from the database tables and stores it in the memory for manipulation, improving performance. If you do not use buffers or array operations, the whole reading process is performed on the database with many table accesses, and performance deteriorates. Also, extensive use of library transformations in the ABAP code reduces performance; since these transformations are not compiled in advance, they are carried out during run-time.
12)Before uploading a high volume of transaction data into InfoCubes, activate the number-range buffer for dimension IDs. The number-range buffer is a parameter that identifies the number of sequential dimension IDs stored in the memory. If you increase the number range before high-volume data upload, you reduce the number of reads from the dimension tables and hence increase the upload performance. Do not forget to set the number-range values back to their original values after the upload. Use transaction code SNRO to maintain the number range buffer values for InfoCubes.
13)Drop the indexes before uploading high-volume data into InfoCubes. Regenerate them after the upload. Indexes on InfoCubes are optimized for reading data from the InfoCubes. If the indexes exist during the upload, BW reads the indexes and tries to insert the records according to the indexes, resulting in poor upload performance. You can automate the dropping and regeneration of the indexes through InfoPackage scheduling. You can drop indexes in the Manage InfoCube screen in the Administrator Workbench.
14)IDoc (intermediate document) archiving improves the extraction and loading performance and can be applied on both BW and R/3 systems. In addition to IDoc archiving, data archiving is available for InfoCubes and ODS objects.
Hope it Helps

@CP..

I need a clarification : Can I use EJBs instead of helper classes for better performance and less network traffic?

My application was designed based on MVC Architecture. But I made some changes to HMV base on my requirements. Servlet invoke helper classes, helper class uses EJBs to communicate with the database. Jsps also uses EJBs to backtrack the results.
I have two EJBs(Stateless), one Servlet, nearly 70 helperclasses, and nearly 800 jsps. Servlet acts as Controler and all database transactions done through EJBs only. Helper classes are having business logic. Based on the request relevant helper classed is invoked by the Servlet, and all database transactions are done through EJBs. Session scope is 'Page' only.
Now I am planning to use EJBs(for business logic) instead on Helper Classes. But before going to do that I need some clarification regarding Network traffic and for better usage of Container resources.
Please suggest me which method (is Helper classes or Using EJBs) is perferable
1) to get better performance and.
2) for less network traffic
3) for better container resource utilization
I thought if I use EJBs, then the network traffic will increase. Because every time it make a remote call to EJBs.
Please give detailed explanation.
thank you,
sudheer

Please suggest me which method (is Helper classes or Using EJBs) is perferable :
1) to get better performance
EJB's have quite a lot of overhead associated with them to support transactions and remoteability. A non-EJB helper class will almost always outperform an EJB. Often considerably. If you plan on making your 70 helper classes EJB's you should expect to see a dramatic decrease in maximum throughput.
2) for less network traffic
There should be no difference. Both architectures will probably make the exact same JDBC calls from the RDBMS's perspective. And since the EJB's and JSP's are co-located there won't be any other additional overhead there either. (You are co-locating your JSP's and EJB's, aren't you?)
3) for better container resource utilization
Again, the EJB version will consume a lot more container resources.

Looking for a high-performance and reliable NAS

Hi,
I have been searching for a high-performance and reliable SOHO NAS storage but I have seen very mixed and contradicting reviews for the products I have looked at so far. From QNAP to Synology to etc.
However I've not found a good review for Promise SOHO NAS devices such NSx700 and NSx600.
Is anybody here using them? If so how would you rate these devices?
Thanks in advance,

Is there a way to view Flash videos on my iMac without downloading Adobe Flash Player? I'm concerned about performance and security with Adobe Flash Player.

If the video is only available in a format that requires Flash player : then no.
However, a great many can also be viewed in an HTML5 version, in which case http://hoyois.github.io/safariextensions/clicktoplugin/ or similar can be set up so that Flash never runs unless you specifically choose it to.

Performance and Sprite objects

I've written an application in Flex 2 that consists of
several accordions containing custom canvas objects, and it is
having performance problems.
I'm running the application within IE 6.0 under Windows 2000.
The application loads an XML file and uses the data to create
custom Sprite objects in the canvases. Each Sprite consists of two
swf images that are loaded using the Loader class, a small
rectangle created by using the Sprite graphics property, and a text
label. In addition, each Sprite is connected to one or more other
Sprites by a line drawn using the Sprite's graphics property. The
Sprites have the capability for being dragged, and for being
highlighted when clicked.
My problem is performance; these Sprites perform slower than
a similiar program that I wrote in ActionScript 2.0. From what I
understand, Flex 2.0, ActionScript 3.0, Flash 9, and the new Sprite
class are supposed to deliver greatly improved performance, but my
new application seems worse than the old one under Flash 7 using
MovieClips. The more Sprites on the screen, the worse the
performance, and the lines seem to contribute to the degradation.
There is way too much code involved to include in this
message, so I'm looking for general info. Is there some basic point
I am missing?
The performance is also degraded when triggering instances of
the Menu and Popup classes. When running the Task Manager during
the application, I've noticed that both Memory Usage and GDI
objects increase whenever I display a Menu or Popup. Both Memory
Usage and GDI objects go up and down, but there is a steady
increase in both metrics as I continue to use Menus and Popups. As
far as I can tell, I am disposing of both types of objects
properly, but it appears that their allocation is remaining in
memory.

Form - Perform and ABAP coding

Hi:
I have a requirement to get vendor address from database and print on the form. I could print only one field only Name1, but not details like Street or country Etc are not getting printed. Even if we pass multiple variables as input and putput variables using perform of form, I think we need to declare only one input as INTTAB STRUCTURE ITCSY and one out put variable as OUTTAB STRUCTURE ITCSY in the ABAP program. In the program I am using Index option like 1, 2 and modifying details of OUTTAB. Is it correct?.
Still I am unable to print complete address on the form.
For this I am unsing Perfom option in the form.
Can you please help in the following:
1) Can I pass one value vendor from form using perform and get back a structure from ABAP program?.
2) I am using following:
         DEFINE &VENDOR_NAME& = ' '
         DEFINE &VENDOR_STREET& = ' '
         PERFORM GET_DATA IN PROGRAM Z_TEST
                   USING &VENDOR_NO&
                   CHANGING &VENDOR_NAME&
                   CHANGING &VENDOR_STREET&
         ENDPERFORM.
For Printing I am using inthe form
                    &VENDOR_NAME&
                    &VENDOR_STREET&
In the ABAP program I am using
FORM GET_DATA TABLES INTTAB STRUCTURE ITCSY
                     OUTTAB1 STRUCTURE ITCSY.
IF SY-SUBRC EQ 0.
    SELECT SINGLE NAME1 STR_SUPPL1
       FROM ADRC
       INTO (V_NAME1,V_STR_SUPPL1)
       WHERE ADDRNUMBER = V_ADRNR.
    IF SY-SUBRC EQ 0.
*- Name1
      READ TABLE OUTTAB1 INDEX 1.
      MOVE V_NAME1 TO OUTTAB1-VALUE.
      MODIFY OUTTAB1 INDEX SY-TABIX.
*- Street
      READ TABLE OUTTAB1 INDEX 2.
      MOVE V_STR_SUPPL1 TO OUTTAB1-VALUE.
      MODIFY OUTTAB1 INDEX SY-TABIX.
ENDIF.
Can you please check above code and let me know if I am doing mistake anywhere?..like passing variables, printing variables on the form and ABAP sub-routine etc.
Please do not copye again same code what is find in SAP ABAP help.
Thanks in advance for your help.
Thanks,
Rama

Your code did not work...
Sorry I did not paste my complete code(when I posted message )as too much code might be confusing. Please find my code below:
FORM GET_DATA TABLES INTTAB STRUCTURE ITCSY
                     OUTTAB1 STRUCTURE ITCSY.
DATA: V_ADRNR          LIKE LFA1-ADRNR,
            V_NAME1          LIKE ADRC-NAME1,
            V_STR_SUPPL1 LIKE ADRC-STR_SUPPL1,
            V_LIFNR             LIKE LFA1-LIFNR.
READ TABLE INTTAB INDEX 1.
V_LIFNR = INTTAB-VALUE.
CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
    EXPORTING
      INPUT = V_LIFNR
    IMPORTING
      OUTPUT = V_LIFNR.
SELECT SINGLE ADRNR
    INTO V_ADRNR
    FROM LFA1
     WHERE LIFNR = V_LIFNR.
IF SY-SUBRC EQ 0.
    SELECT SINGLE NAME1 STR_SUPPL1
       FROM ADRC
       INTO (V_NAME1,V_STR_SUPPL1)
       WHERE ADDRNUMBER = V_ADRNR.
    IF SY-SUBRC EQ 0.
*- Name1
      READ TABLE OUTTAB1 INDEX 1.
      MOVE V_NAME1 TO OUTTAB1-VALUE.
      MODIFY OUTTAB1 INDEX SY-TABIX.
*- Name1
      READ TABLE OUTTAB1 INDEX 2.
      MOVE V_STR_SUPPL1 TO OUTTAB1-VALUE.
      APPEND OUTTAB1.
    ELSE.
      READ TABLE OUTTAB1 INDEX 1.
      MOVE 'NO NAME' TO OUTTAB1-VALUE.
      MODIFY OUTTAB1 INDEX SY-TABIX.
    ENDIF.
ENDIF.
ENDFORM.
I am not sure where the mistake can be in the SAP-Form or in the ABAP Subroutine code....
Thanks,
