"Analyze ... validate structure cascade" and performance

Hello!
Does commands
Analyze cluster ... validate structure cascade;
Analyze table ... validate structure cascade;ivalidates shared cursors in SGA ?
If the statistics collected by this clause are not used by the Oracle Database optimizer, this operation does not any impacts of performance, am I right ?
Thanks and regards,

Where is the output of analyze table name validate structure cascade

Hi,
database version:8.1.7.0.0
os :solaris 5.9
since i used to get ORA-00600: INTERNAL ERROR CODE, ARGUMENTS: [25012], [7], [39] and i need to validate the table and this table is very huge(200 gb) where will be the output generated if any error is there in table including indexes.

ANALYZE TABLE ... VALIDATE STRUCTURE

I did ANALYZE TABLE ... VALIDATE STRUCTURE CASCADE. MetaLink says output
is in trace file in udump location. Well it is not. Does anyone
know where Oracle does hide this info?

Oracle is not hiding anything.
There will be only info when there is something wrong.
Rather than discussing irrelevant issues like defragmenting tablespaces, rebuilding indices etc,etc why don't you start reading the documentation?
You seem to have too much time on your hands.

Question about "ANALYZE TABLE VALIDATE STRUCTURE" in 9i

Hi,
I have a 9.2.0.8 database on AIX. After a storage copy of my produztion datafiles from a site to another I performed a DBV to ensure that all copies were correct. After I correctly started my db.
Now, could be a good idea to perform a "ANALYZE TABLE tabname VALIDATE STRUCTURE;" statement on all table of my database to be sure that I haven't a corruption? Are there cons performing this operation?

Just take full backup through RMAN, and validate that backup.

Diff b/w Run time Analyizer(se30),Sql Trace (st05) and Performance Analyzie

Can any one tell me the Diff b/w Run time Analyizer(se30),Sql Trace (st05) and Performance Analyzie(al21) ?

Hi
these all are doing t he same thing that is checking the program for better performance
Tools for Performance Analysis
Run time analysis transaction SE30
SQL Trace transaction ST05
Extended Program Check (SLIN)
Code Inspector ( SCI)
Run time analysis transaction SE30 :This transaction gives all the analysis of an ABAP program with respect to the database and the non-database processing.
SQL Trace transaction ST05: The trace list has many lines that are not related to the SELECT statement in the ABAP program. This is because the execution of any ABAP program requires additional administrative SQL calls. To restrict the list output, use the filter introducing the trace list.
The trace list contains different SQL statements simultaneously related to the one SELECT statement in the ABAP program. This is because the R/3 Database Interface - a sophisticated component of the R/3 Application Server - maps every Open SQL statement to one or a series of physical database calls and brings it to execution. This mapping, crucial to R/3s performance, depends on the particular call and database system. For example, the SELECT-ENDSELECT loop on a particular database table of the ABAP program would be mapped to a sequence PREPARE-OPEN-FETCH of physical calls in an Oracle environment.
The WHERE clause in the trace list's SQL statement is different from the WHERE clause in the ABAP statement. This is because in an R/3 system, a client is a self-contained unit with separate master records and its own set of table data (in commercial, organizational, and technical terms). With ABAP, every Open SQL statement automatically executes within the correct client environment. For this reason, a condition with the actual client code is added to every WHERE clause if a client field is a component of the searched table.
To see a statement's execution plan, just position the cursor on the PREPARE statement and choose Explain SQL. A detailed explanation of the execution plan depends on the database system in use.
Extended Program Check
This can be called in through transaction SE38 or through transaction SLIN. This indicates possible problems that may cause performance problems.
Code Inspector (SCI)
You can call the Code Inspector from the ABAP Editor (SE38), the Function Builder (SE37), the Class Builder (SE24), or as a separate transaction (SCI).
The Code Inspector indicates possible problems. However, note that, especially with performance issues: There is no rule without exception. If a program passes an inspection, it does not necessarily mean that this program will have no performance problems.

In-Place Element Structures, References and Pointers, Compiler Optimization, and General Stupidity

[The title of this forum is "Labview Ideas". Although this is NOT a direct suggestion for a change or addition to Labview, it seems appropriate to me to post it in this forum.]
In-Place Element Structures, References and Pointers, Compiler Optimization, and General Stupidity
I'd like to see NI actually start a round-table discussion about VI references, Data Value references, local variables, compiler optimizations, etc. I'm a C programmer; I'm used to pointers. They are simple, functional, and well defined. If you know the data type of an object and have a pointer to it, you have the object. I am used to compilers that optimize without the user having to go to weird lengths to arrange it.
The 'reference' you get when you right click and "Create Reference" on a control or indicator seems to be merely a shorthand read/write version of the Value property that can't be wired into a flow-of-control (like the error wire) and so causes synchronization issues and race conditions. I try not to use local variables.
I use references a lot like C pointers; I pass items to SubVIs using references. But the use of references (as compared to C pointers) is really limited, and the implementation is insconsistent, not factorial in capabilites, and buggy. For instance, why can you pass an array by reference and NOT be able to determine the size of the array EXCEPT by dereferencing it and using the "Size Array" VI? I can even get references for all array elements; but I don't know how many there are...! Since arrays are represented internally in Labview as handles, and consist of basically a C-style pointer to the data, and array sizing information, why is the array handle opaque? Why doesn't the reference include operators to look at the referenced handle without instantiating a copy of the array? Why isn't there a "Size Array From Reference" VI in the library that doesn't instantiate a copy of the array locally, but just looks at the array handle?
Data Value references seem to have been invented solely for the "In-Place Element Structure". Having to write the code to obtain the Data Value Reference before using the In-Place Element Structure simply points out how different a Labview reference is from a C pointer. The Labview help page for Data Value References simply says "Creates a reference to data that you can use to transfer and access the data in a serialized way.". I've had programmers ask me if this means that the data must be accessed sequentially (serially)...!!! What exactly does that mean? For those of use who can read between the lines, it means that Labview obtains a semaphore protecting the data references so that only one thread can modify it at a time. Is that the only reason for Data Value References? To provide something that implements the semaphore???
The In-Place Element Structure talks about minimizing copying of data and compiler optimization. Those kind of optimizations are built in to the compiler in virtually every other language... with no special 'construct' needing to be placed around the code to identify that it can be performed without a local copy. Are you telling me that the Labview compiler is so stupid that it can't identify certain code threads as needing to be single-threaded when optimizing? That the USER has to wrap the code in semaphores before the compiler can figure out it should optimize??? That the compiler cannot implement single threading of parts of the user's code to improve execution efficiency?
Instead of depending on the user base to send in suggestions one-at-a-time it would be nice if NI would actually host discussions aimed at coming up with a coherent and comprehensive way to handle pointers/references/optimization etc. One of the reasons Labview is so scattered is because individual ideas are evaluated and included without any group discussion about the total environment. How about a MODERATED group, available by invitation only (based on NI interactions with users in person, via support, and on the web) to try and get discussions about Labview evolution going?
Based solely on the number of Labview bugs I've encountered and reported, I'd guess this has never been done, with the user community, or within NI itself.....

Here are some articles that can help provide some insights into LabVIEW programming and the LabVIEW compiler. They are both interesting and recommended reading for all intermediate-to-advanced LabVIEW programmers.
NI LabVIEW Compiler: Under the Hood
VI Memory Usage
The second article is a little out-of-date, as it doesn't discuss some of the newer technologies available such as the In-Place Element Structure you were referring to. However, many of the general concepts still apply. Some general notes from your post:
1. I think part of your confusion is that you are trying to use control references and local variables like you would use variables in a C program. This is not a good analogy. Control references are references to user interface controls, and should almost always be used to control the behavior and appearance of those controls, not to store or transmit data like a pointer. LabVIEW is a dataflow language. Data is intended to be stored or transmitted through wires in most cases, not in references. It is admittedly difficult to make this transition for some text-based programmers. Programming efficiently in LabVIEW sometimes requires a different mindset.
2. The LabVIEW compiler, while by no means perfect, is a complicated, feature-rich set of machinery that includes a large and growing set of optimizations. Many of these are described in the first link I posted. This includes optimizations you'd find in many programming environments, such as dead code elimination, inlining, and constant folding. One optimization in particular is called inplaceness, which is where LabVIEW determines when buffers can be reused. Contrary to your statement, the In-Place Element Structure is not always required for this optimization to take place. There are many circumstances (dating back years before the IPE structure) where LabVIEW can determine inplaceness and reuse buffers. The IPE structure simply helps users enforce inplaceness in some situations where it's not clear enough on the diagram for the LabVIEW compiler to make that determination.
The more you learn about programming in LabVIEW, the more you realize that inplaceness itself is the closest analogy to pointers in C, not control references or data references or other such things. Those features have their place, but core, fundamental LabVIEW programming does not require them.

Forms and Reports: Automated Test tools - functionality AND performance

All,
I'm looking to get a few leads on an automated test tools that may be used to validate Oracle forms and reports (see my software configuration below). I'm looking for tools that can automate both functional tests and performance. By this I mean;
Functional Testing:
* Use of shortcut keys
* Navigation between fields
* Screen organisation (filed locations)
* Exercise forms validation (bad input values)
* Provide values to forms and simulate user commit, and go and verify database state is as expected
Performance Testing:
* carry out tests for fixed user load
* carry out tests for scaled step increase in user load
* automated collection of log files and metrics during test
So far I have:
http://www.neotys.com/
Thanks in advance for your response.
Mathew Butler
Configuration:
Red Hat Enterprise Linux x86-64 architecture v4.5 64 bit
Oracle Application Server 10.1.2.0.2 ( with patch 10.1.2.3 )
Oracle Developer Suite (Oracle Forms and Reports) V10.1.2.0.2 ( with patch 10.1.2.3 )
Oracle JInitiator 1.3.1.17 or later
Microsoft Internet Explorer 6

are there any tools for doing this activity like oracle recommended tools?
Your question is unclear. As IK mentioned, the only tool you need is a new version of Oracle Forms/Reports. Open your v10 modules in a v11 Builder and select Save. You now have a v11 module. Doing a "Compile All PL/SQL" before saving is a good idea, but not required. The Builders and utilites provided with the version 11 installation are the only supported tools for upgrading your application. If you are trying to do the conversion of many Forms files in a scripted manner, you can use the Forms compiler in a script. Generating new "X" files will also update the source modules (fmb, mmb, pll). See MyOracleSupport Note 955143.1
Also included in the installation in the Forms Migration Assistant. Although it is more useful to people coming from older versions, it can also be used to move from v10 to 11. It allows you to select more than one file at a time. Documentation for this utility can be found in the Forms Upgrade Guide.

READ_TEXT IN FORM AND PERFORM

Hi all.
I have an issue in Scripts.
we are using standard program as print progarm and a zform as form.
we want to print some text in themain window of the form.
for that one I created a new progarm for form and perform.
in taht form i am using this function module read_text to read the text.
i sending all this text to an internal table.
up to thuis ok...
While the data transfering from form to perform (i.e to the form(script)) only the last line of the internal table is transfering.
and i declared the exporting TABLE OF TYPE ITCSY.
CAN ANY BODY HELP TO SOLVE THIS ISSUE,
THANKS IN ADVANCE,
rEGARDS,
ESWAR.M

Hi venkat,
1. while calling subroutines from sapscripts,
there is a special technique,
which has got its own limitations.
2.
FORM abc
TABLES
in_tab STRUCTURE itcsy
out_tab STRUCTURE itcsy.
ENDFORM.
3. The perform in se38 program should be of the
above format only.
4.<b> We cannot pass internal tables.</b>
5. Rather we need to pass
VARIABLE NAME
VARIABLE VALUE
(see the structure of itcsy in se11)
6. In this form, we have to read
the internal table in_tab
to capture the variable name and its value.
7. Similary, to return the values,
we have to put one record (for each variable)
in out_tab.

WAS http workload and performance log files - where are they?

Hi,
Were can the http "log files" be found for WebAS? We are looking for the workload and performance data comparable to what is found in the IIS logs or W3C logs for other classes of web servers. We want to load this data into BW Business content area 0WEB and or third party tools (Web Trends) for analysis of statistics like number of hits per web page, duration of web site visit...
Thanks, in advance, for your guidance.
Janet H.

Hi Janet,
if you go down to a directory something like: C:\usr\sap\J2E\JC00\j2ee\admin\logviewer-standalone. There you can find the standalone logviewer. Opening this one under serverxx/system/httpaccess you should find a file called responses.trc. This includes the messages. The fiel is in anequivalent structure under the server.

Connection between Structure Field and Table Field

Hello everybody,
I'm trying to find a connection between a field in the structure and the actual filed in the table of the database. For example in the structure CAUFVD you have the field PLNNR. This information is stored in the table AFFL in the field PLNNR.
In the transaction SE84 you can display a structure with all it's fields but I don't see anywhere from which table and field the information is gathered.
Can you please help me in finding the connection between the structure field and the table field in the database in which the displayed information is stored?
Thanks and best regards,

SAP - PP-KeyUser

Double-click on the structure field and you can do a where-used to find the codepoints, interface usage, etc. You might find it that way. You could also look at the flow logic of your screen and try to trace it back. Otherwise, you'd have to use watchpoints, the debugger, runtime analysis or various other developer tools to find the data population. If you are a user and not a developer as your signature indicates, you might need to find a developer for this. Sometimes, it can be incredibly frustrating with SAP because the data field will be handed off 4 or 5 times before it actually reaches its destination field. Unfortunately, I haven't worked with PP in at least 10 years so I can't give you a better answer; maybe someone else can.

ASO MDX member formula and performance

Hi,
I am doing some testing about MDX formulas and performance. I found a performance issue but I can not understand why is taking so long time a report.
The situation is:
I create a report or a MDX query with:
6 dimensions in row and 1 dimension in column
rows:
Period - Filtered using a member
Year - Filtered using a member
Relationship Manager - Filtered using a member
Report Type - Filtered using a member
Local Relationship Manager - 4400 members level 0
Global Relationship Manager - 10400 members level 0
Column:
Account dimension, only a member
The member selected for Report Type (RM.Local) has a formula
My Report Type dimension has 10 members, there is one member where I store data called : RM.Input
My first test was
RM.Local his formula is [RM.Input] , the report is run in 1 second
RM.Local his formula is ([RM.Input],[MTD]) where MTD is a member level 0 store in my view dimension. The report run in 20 minutes. I was not expecting so bad performance when I only pointing at [RM.Input],[MTD]
Do you consider this time is reasonable when I am using this formula?
The mdx report is:
With
set [_Local Relationship Manager3] as 'Descendants([All Local Relationship Managers], 2)' = level 0 members
set [_Global Relationship Manager4] as '[Global Relationship Manager].Generations(4).members' = level 0 members
set [_Period0] as '{[Period].[Oct]}'
set [_Relationship Manager4] as '{[Relationship Manager].[Dummy1)]}'
set [_Report Type0] as '{[Report Type].[RM.Local]}'
set [_Year2] as '{[Year].[FY-2013]}'
select
{ [Account].[Expenses]
} on columns,
NON EMPTY {crossjoin({[_Local Relationship Manager3]},crossjoin({[_Global Relationship Manager4]},crossjoin({[_Period0]},crossjoin({[_Relationship Manager4]},crossjoin({[_Report Type0]},{[_Year2]})))))} properties MEMBER_NAME, GEN_NUMBER, [Global Relationship Manager].[MEMBER_UNIQUE_NAME], [Global Relationship Manager].[Memnor], [Local Relationship Manager].[MEMBER_UNIQUE_NAME], [Local Relationship Manager].[Memnor], [Relationship Manager].[MEMBER_UNIQUE_NAME], [Relationship Manager].[Memnor], [Period].[Default], [Report Type].[Default], [Year].[MEMBER_UNIQUE_NAME], [Year].[Memnor] on rows
from [DICISRM.DICISRM]

Ok Try this one
But here you have to change the MDX formula every month.
Year
--FY2009
--FY2010
--FY2011
--FY2012
Period
--TotalYear
----Qtr1
-------Jan
-------Feb
-------Mar
Let say if you're CurrentYear is FY2011 and you're Current Month is March then you're MDX will be
case when contains([Year].CurrentMember,MemberRange([FY2009],[FY2010])) and contains([Period].CurrentMember,MemberRange([Jan],[Feb]))
Then
B
else
C
end
For the Next month you just have to make a change in the MemberRange I.e.,(Replace Feb with Mar)
*case when contains([Year].CurrentMember,MemberRange([FY2009],[FY2010])) and contains([Period].CurrentMember,MemberRange([Jan],[Mar]))*
Then
B
else
C
end
I tested it and Its working fine.
I think this will solve you're problem but there might be a more elegant solution out there.

How can I optimize my hard disk drive usage and performance in Windows 8 or Windows 7?

QuestionHow can I optimize my hard disk drive usage and performance in Windows 8 or Windows 7?
AnswerThere are a few simple steps you can take to ensure your hard disk drive is used optimally.
Use Toshiba HDD Protection
Many Toshiba laptops come with a program called Toshiba HDD Protection pre-installed. This program helps to protect your hard disk drive from being damaged due to falls or impacts. By default, it should already be enabled. You might be tempted to lower the detection levels in this application, but doing so could cause your hard disk drive to be damaged. Remember that while the application can reduce the chance of damage, you should still avoid allowing the laptop to fall or suffer rapid impacts.
For more information on this utility, see the following article:
TOSHIBA HDD Protection
Optimize the drive
Windows 8 and Windows 7 optimize hard disk drives automatically through a process called defragmentation. Unless you've disabled this, you don't need to do anything. If you have disabled this and want to run the process, you can still do so.
In Windows 8, search for "Defrag" at the Windows Start screen and select "Defragment and optimize your drives."
In Windows 7, search for "Defrag" in the Start Menu's search field and select "Disk defragmenter."
You can use this tool to optimize your hard disk drives, allowing Windows to find needed files faster.
Remove items from startup
Some applications run automatically when Windows starts. This can add additional functionality, but it also decreases the performance of your computer. Sometimes you might want to disable certain programs from starting automatically.
In Windows 8, search for "Task Manager" at the Start screen. Select the "Startup" tab. Select an application you'd like to disable from starting automatically and then click the "Disable" button in the lower-right.
In Windows 7, type "msconfig" in the Start Menu's search field and press ENTER. Uncheck the boxes next to applications you'd like to disable from starting automatically.
You should be sure of the purpose of an application before disabling it from starting automatically. Some applications might be important. If in doubt, you might consider searching on the Web to discover more information about a program. Remember that if you find that you disabled something vital, you can always re-enable it.
