What is spin dump

i have iMac desktop and i am having a problem with running yahoo. other web sights seem to be ok just loading slow or not the whole thing. I go under activity monitor-Network and it says com.apple.geod not responsive. com.apple.geod and Flash Player (safari internet plug-in 3069) are in red highlight. is spin dump the same as cleaning up your hard drive for windows. I do not have Airport anymore and want to delete it from my comp. how can i do this.

What Does Spin Dump Do?

Does spin dump knock down the Memory used when you view Activity Monitor? Can someone tell me how it actually works?

What is Short Dump Analysis and secendry index ?

Dear Experts .
1.) What is purpose of T-codes SE30 and ST22 ?
What is Short Dump Analysis ?
2.) What is secendry index , How to use it ? How it effects the Performance of a report ?
Please it is urgent ...

Hi
A dump analysis is a comprehensive list that should enable you to identify the causes and possible solutions of program errors. The ABAP Workbench generates a short dump whenever a report or transaction terminates due to a serious error. The system enters the error in the system log and writes a snapshot of the program at the moment when it terminated into a special database table called SNAP.
Dump analyses give the user or programmer information about the causes of the error that has caused the program to terminate. Experienced users can use them to identify very quickly where and why this occurred. He or she can them solve the problem.
The snapshot contains the following information:
Why the program has terminated
What caused the program termination
Where in the program code the termination occurred
What you can do to correct the error
The values of the relevant system fields when the program terminated
The calls or events that were active when the program terminated
Any other programs that are affected.

Index: Technical key of a database table.
Primary index: The primary index contains the key fields of the table and a pointer to the non-key fields of the table. The primary index is created automatically when the table is created in the database.
Secondary index: Additional indexes could be created considering the most frequently accessed dimensions of the table.
Structure of an Index
An index can be used to speed up the selection of data records from a table.
An index can be considered to be a copy of a database table reduced to certain fields. The data is stored in sorted form in this copy. This sorting permits fast access to the records of the table (for example using a binary search). Not all of the fields of the table are contained in the index. The index also contains a pointer from the index entry to the corresponding table entry to permit all the field contents to be read.
When creating indexes, please note that:
An index can only be used up to the last specified field in the selection! The fields which are specified in the WHERE clause for a large number of selections should be in the first position.
Only those fields whose values significantly restrict the amount of data are meaningful in an index.
When you change a data record of a table, you must adjust the index sorting. Tables whose contents are frequently changed therefore should not have too many indexes.
Make sure that the indexes on a table are as disjunctive as possible.
(That is they should contain as few fields in common as possible. If two indexes on a table have a large number of common fields, this could make it more difficult for the optimizer to choose the most selective index.)
Accessing tables using Indexes
The database optimizer decides which index on the table should be used by the database to access data records.
You must distinguish between the primary index and secondary indexes of a table. The primary index contains the key fields of the table. The primary index is automatically created in the database when the table is activated. If a large table is frequently accessed such that it is not possible to apply primary index sorting, you should create secondary indexes for the table.
The indexes on a table have a three-character index ID. '0' is reserved for the primary index. Customers can create their own indexes on SAP tables; their IDs must begin with Y or Z.
If the index fields have key function, i.e. they already uniquely identify each record of the table, an index can be called a unique index. This ensures that there are no duplicate index fields in the database.
When you define a secondary index in the ABAP Dictionary, you can specify whether it should be created on the database when it is activated. Some indexes only result in a gain in performance for certain database systems. You can therefore specify a list of database systems when you define an index. The index is then only created on the specified database systems when activated

Hi Ramy,
For Server 2012R2 the absolute minimum system drive is 32Gb but this assume you have limited RAM or have your Page file located on another drive. It used to be best practice to setup a small page file but MS PFE now suggest leaving windows to manage
the page file size.
Obviously this is not always possible depending on the amount of RAM in the system, but base the system drive around this or offload the Page file to perhaps another drive. On top of this you also need space for the memory dump to be written, potentially
again up to the size of the RAM. Assuming you fire the machine back up after a crash, you need space for the OS, the Page File plus space for the associated dump file.
There is a nice little article here that maybe of assistance: http://social.technet.microsoft.com/wiki/contents/articles/13383.best-practices-for-page-file-and-minimum-drive-size-for-os-partition-on-windows-servers.aspx

How to tell what type of dump?

Hi,
I was given a backup file EXPDAT.dmp to be loaded at my test database.
It was not indicated what type of export created this dump.
How do I know if it is at output of exp or expdp?
Thanks a lot

What is the dump file size limit?

Hello all,
Can somebody tell me what is the maximum size of the dump file created by export utility in Oracle? Is there any maximum size applicable to dump file?
Thanks in advance

Hi,
Later Oracle 8.1.6, is no more Oracle limitation on dump file, with restriction 2Gb for full 32-bits OS (32-bit with 32-bit files). The maximum value that can be stored in a file is dependent on your operating system.

What causes spinning beach ball upon waking from sleep

I have a 4 year old iMac that has recently developed an intermittent problem. If I put it to sleep, sometimes on waking up, the hard drive access seems to stop. I hear a tap sound as though it was trying to read the disk, but it gets stuck and a spinning beach ball appears instead of the cursor. I can move it around, but I cannot perform any actions. The ball will stay forever if I let it.
Another variation occurs shortly after wake-up, where I start to click on a file on the desktop or even an icon in the Dock. The name will become highlighted and then the same spinning beach ball appears.
The only cure for the behavior has been to shut it down and reboot. It then works fine.
The weird thing is that I have just been using it for 6 hours straight with out any hassles... until I will put it to sleep!
I have tried running Disk Utility from the Leopard System Disk as well as repairing permissions and I have used Disk Warrior 4 . It seemed to allow about 6-8 sleep cycles before the symptoms re-appeared.
I verified the disk and repaired the permissions again yesterday and all seemed OK. Yet today, when I started up from sleep. the system froze. The only cure so far is to never allow the hard drive to sleep. I put the display to sleep after 15 minutes but the hard drive continues to spin.
I am concerned that not sleeping the hard drive will do harm to it.
I am using OS 10.5.8 on a 233 Ghz Core 2 Duo iMac
I have Parallels 4 installed and cannot tell you if the problems started after a PC session.

HI Studio Guy,
Welcome to the forums. When ever your having trouble with a computer; it's really a good idea to back every thing up. If your not backing up; http://support.apple.com/kb/ht1427 explains how to back up your computer to an external hard drive. (assuming your using 10.5 or 10.6)
You could try running a hardware test on the computer. http://support.apple.com/kb/ht1509
You could try a safeboot, it can repair lots of issues. http://support.apple.com/kb/ht1455
This article explains how to delete the sleep image; a bad sleep image can cause wake from sleep issues. http://osxdaily.com/2010/10/11/sleepimage-mac/
But if your hard drive is rapidly making a taping noise you may want to take it to a genius bar; they might recommend replacing the hard drive. http://www.apple.com/retail/geniusbar/

I am getting dump error while running one report in one select query

Hi,
While running a report program, I am getting a dump error in one select query. So could you please correct the select query so that I can't face the dump error.
SELECT vbeln parvw kunnr INTO CORRESPONDING FIELDS OF TABLE l_t_vbpa
FROM vbpa
FOR ALL ENTRIES IN l_t_backorder_item
WHERE vbeln = l_t_backorder_item-vbeln AND
( ( parvw = c_we AND kunnr IN rng_shipto ) OR ( parvw = c_ag AND
kunnr IN rng_soldto ) ) .

Edited by: Thomas Zloch on Apr 30, 2010 12:31 PM

Hi Bansidhar,
It would be helpful if you could tell what type of dump it is.
If it is a timeout you should check whether l_t_backorder_item is empty - in this case ALL document numbers are selected. f you get the timeout with a populated table consider converting the l_t_backorder_item table into one ore more ranges tables - the select with ranges tables is way quicker than 'for all entries'. But take care the ranges table has not to many entries - the SAP SQL converter puts this into one huge SQL statement and this might become too big to be handled by the database (depends on the actual underlying database).
I would also consider splitting the SELECT into two (2nd one with 'appending into table') to make the code easier to understand It also helps the database system determining a strategy for the select.

SUBMIT via selection screen and return gives dump

Hi Guys,
When i have used SUBMIT via SELECTION SCREEN and RETURN, it gave me the selection screen and subsequent report is executed properly without an error and when i pressed back button, it went to selection screen without any issues but the problem is when i press back from the selection screen it gives me a dump. Could you guys think of what would be the probelm.
Thanks in Advance.

Tuning, short dumps

What are techniques used for tuning query performance? Please explain in detail?
What are short dumps how can we check?
What methodologies we follow for the PSA cleansing? Where exactly is the PSA change log where we can delete the request based on timestamp details am using BW 3.1c?

Hi,
This info may be helpful.
Tuning query performance
General tips
Using aggregates and compression.
Using less and complex cell definitions if possible.
1. Avoid using too many nav. attr
2. Avoid RKF and CKF
3. Many chars in row.
By using T-codes ST03 or ST03N
Go to transaction ST03 > switch to expert mode > from left side menu > and there in system load history and distribution for a particual day > check query execution time.
/people/andreas.vogel/blog/2007/04/08/statistical-records-part-4-how-to-read-st03n-datasets-from-db-in-nw2004
/people/andreas.vogel/blog/2007/03/16/how-to-read-st03n-datasets-from-db
Try table rsddstats to get the statistics
Using cache memoery will decrease the loading time of the report.
Run reporting agent at night and sending results to email.This will ensure use of OLAP cache. So later report execution will retrieve the result faster from the OLAP cache.
Also try
1. Use different parameters in ST03 to see the two important parameters aggregation ratio and records transferred to F/E to DB selected.
2. Use the program SAP_INFOCUBE_DESIGNS (Performance of BW infocubes) to see the aggregation ratio for the cube. If the cube does not appear in the list of this report, try to run RSRV checks on the cube and aggregates.
Go to SE38 > Run the program SAP_INFOCUBE_DESIGNS
It will shown dimension Vs Fact tables Size in percent.If you mean speed of queries on a cube as performance metric of cube,measure query runtime.
3. --- sign is the valuation of the aggregate. You can say -3 is the valuation of the aggregate design and usage. ++ means that its compression is good and access is also more (in effect, performance is good). If you check its compression ratio, it must be good. -- means the compression ratio is not so good and access is also not so good (performance is not so good).The more is the positives...more is useful the aggregate and more it satisfies the number of queries. The greater the number of minus signs, the worse the evaluation of the aggregate. The larger the number of plus signs, the better the evaluation of the aggregate.
if "-----" then it means it just an overhead. Aggregate can potentially be deleted and "+++++" means Aggregate is potentially very useful.

http://help.sap.com/saphelp_nw70/helpdata/en/60/f0fb411e255f24e10000000a1550b0/frameset.htm
4. Run your query in RSRT and run the query in the debug mode. Select "Display Aggregates Found" and "Do not use cache" in the debug mode. This will tell you if it hit any aggregates while running. If it does not show any aggregates, you might want to redesign your aggregates for the query.
Also your query performance can depend upon criteria and since you have given selection only on one infoprovider...just check if you are selecting huge amount of data in the report
Check for the query read mode in RSRT.(whether its A,X or H)..advisable read mode is X.
5. In BI 7 statistics need to be activated for ST03 and BI admin cockpit to work.
By implementing BW Statistics Business Content - you need to install, feed data and through ready made reports which for analysis.

Selection screen report dump on "start-of-selection "event.

Hello ,
I created report with selection screen . When I run the transaction and hit execute F8 the program is NOT executed at all and transaction ends up on "SAP easy access" screen.
I checked in debugger and I realized that program is executed until the event "start-of-selection" on that line execution stops.
In that moment sy-ucomm = 'CRET'
Although when the program is executed from SE80 ( direct execution ) everything works well in this case sy- ucomm is initial ( no value)
Please advice .
Krsto
at selection-screen.
perform layout_validation .
start-of-selection. - execution stop s on this line
select * from zlabveri

so what did the dump (read it in trans ST22) tell you the problem is? Read the dump and fix the error. Forum participants have no psychic antennae nor can they remote view your dumps
