Collect Thread Dump using Script and direct to separate log file

Dear Legends,
I request you to provide me some useful guide lines to collect Thread Dump using script in linux and redirect the output to a separate log file, not the STDOUT file. If it is redirecting to STDOUT then how to extract only the thread stack to a separate log file.
i used
ps -ef | grep java
kill -3 <pid> >> ss1_td.log
but it is not providing the thread stack to the log file.
Anykind of help would be appreciated much.
Regards,
Karthik

Hi Ram,
Really a great and useful script for me at the right time. It solved my requirement and i made some changes to my requirement and the script it working fine to collect the thread dump and even i have checked the thread dump with SAMURAI works fine.
Helpful site also refer sites like these which contains more valuable things for weblogic. We will meet in the forums again.
Note: also please update several links available in the site like UNIX scripts, WLST, Python etc.

Line items AND GENERIC EXTRACTION

what does line items exactly mean in DATASOURCES
AND WHAT ARE DELTA TYPE EXTRACTIONS IN GENERIC
TIME STAMPING
CALENDAR DAY
NUMERICAL POINTER
COULD ANY PLEASE EXPLAIN THE DIFFERNCE AND IN WHAT SCENARIOS WE USE IT ...
LOOKING FOR YOUR REPLY

Hi Guru,
Check below doc & thread for Line Item Dimension:
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/a7f2f294-0501-0010-11bb-80e0d67c3e4a
Line Item Dimenstion
If a field (date, progressive document number, timestamp) exists in the extract structure of a DataSource that contains values which increase monotonously over time, you can define delta capability for this DataSource. If such a delta-relevant field exists in the extract structure, such as a timestamp, the system determines the data volume transferred in the delta method by comparing the maximum value transferred with the last load with the amount of data that has since entered the system. Only the data that has newly arrived is transferred.
To get the delta, generic delta management translates the update mode into a selection criterion. The selection of the request is enhanced with an interval for the delta-relevant field. The lower limit of the interval is known from the previous extraction. The upper limit is taken from the current value, such as the timestamp or the time of extraction. You can use security intervals to ensure that all data is taken into consideration in the extractions (The purpose of a security interval is to make the system take into consideration records that appear during the extraction process but which remain unextracted -since they have yet to be saved- during the next extraction; you have the option of adding a security interval to the upper limit/lower limit of the interval).
After the data request was transferred to the extractor, and the data was extracted, the extractor then informs generic delta management that the pointer can be set to the upper limit of the previously returned interval.
To have a clear idea:
1. If delta field is Date (Record Create Date or change date), then use Upper Limit of 1 day.
This will load Delta in BW as of yesterday. Leave Lower limit blank.
2. If delta field is Time Stamp, then use Upper Limit of equal to 1800 Seconds (30 minutes).
This will load Delta in BW as of 30 minutes old. Leave Lower limit blank.
3. If delta field is a Numeric Pointer i.e. generated record # like in GLPCA table, then use
Lower Limit. Use count 10-100. Leave upper limit blank. If value 10 is used then last 10
records will be loaded again. If a record is created when load was running, those records
may get lost. To prevent this situation, lower limit can be used to backup the starting
sequence number. This may result in some records being processed more than once.

Difference between Customer Generated Extractors and Generic Extractors

Hi all,
Can anyone please tell me the difference between Customer Generated Extractors and Generic Extractors. I know that for all modules Generic extraction is possible by creating a datasource(RSO2) on top of a table, View or SAP Query in SE11. What are customer generated extractors like LIS, CO/PA and FI/SL.
What kind of extraction is used for FI/AR and FI/AP. To my understanding we have BW Content Extractors. Can anyone explain the extraction method and delta extraction for AR and AP.
Thanks,
Sabrina.

Hi,
Customer generated extractors are running on top of statistics data collection process in R/3. They extract data from statistical tables already available in R/3 and also use the mechanism already provided in R/3 to capture the delta.
For example, PO data goes to statistical table S012 (it is an LIS table) and you can build a generated extractor on top of it. The difference between such extractor and a generic one is the fact that these extractors (eg LIS) use the same mechanism of capturing delta that the statistics table was doing (for example data that goes into S012 is also captured by these generated extractors). Some system tables and structures are generated automatically to support this functionality, you do not have to develop anything for this.
Generic extractors on the other hand simply let you pull data from table/view/query etc. You have to develop code/functionality to support delta capturing for such extractors. If you built a generic extractor on top of S012 (it is a statistical table - LIS), you can pull its data to BW, but you do not have the delta capturing functionality in such case, you will have to code it yourself.
As a thumb rule, you go with the standard/generated extractors, and use generic extractors only if it is necessary to be so.
FI/AR and FI/AP extractors are part of business content (I think) and support delta functionality. To get detailed info on these, you can also look at help documentation -

Customer and Generic extraction difference ?

Hi ya,
Could any body tell me the difference between the customer and Generic extractions.what are the extraction steps?
Regards.
H

Hi,
In Generic extraction we have to fetch the data from table/view/funtion module.T.code RSO2.
Replicate the data source in bw and send into data target through ods(recommandable).
In customized extraction sap provided LIS,LO-COCKPIT,CO-PA,FI-SL etc,in these sap provides extract stuructures.From the extract structures we have to fetch the data and replicate the data into bw and push into the data targets.

How to do basic LO extraction for SAP-R3-BW
1. Go to transaction code RSA3 and see if any data is available related to your DataSource. If data is there in RSA3 then go to transaction code LBWG (Delete Setup data) and delete the data by entering the application name.
2. Go to transaction SBIW --> Settings for Application Specific Datasource --> Logistics --> Managing extract structures --> Initialization --> Filling the Setup table --> Application specific setup of statistical data --> perform setup (relevant application)
3. In OLI*** (for example OLI7BW for Statistical setup for old documents : Orders) give the name of the run and execute. Now all the available records from R/3 will be loaded to setup tables.
4. Go to transaction RSA3 and check the data.
5. Go to transaction LBWE and make sure the update mode for the corresponding DataSource is serialized V3 update.
6. Go to BW system and create infopackage and under the update tab select the initialize delta process. And schedule the package. Now all the data available in the setup tables are now loaded into the data target.
7.Now for the delta records go to LBWE in R/3 and change the update mode for the corresponding DataSource to Direct/Queue delta. By doing this record will bypass SM13 and directly go to RSA7. Go to transaction code RSA7 there you can see green light # Once the new records are added immediately you can see the record in RSA7.
8.Go to BW system and create a new infopackage for delta loads. Double click on new infopackage. Under update tab you can see the delta update radio button.
9.Now you can go to your data target and see the delta record.
find your scenario and find what data sources do you need on R3 side and ensure they are active as well:
http://help.sap.com/saphelp_nw04/helpdata/en/37/5fb13cd0500255e10000000a114084/frameset.htm
find your scenario -> data sources -> go to R3 -> sbiw and activate required data source
replicate data sources in BW:
RSA1 -> source systems -> right click on your source system -> replicate
then activate your BC:
service.sap.com/bi -> BI Business Content -> General Information -> SAP BW Business Content - Activation
and execute infopackage (it should be delivered with BC)

Data Cache and Generic Cache

Hello,
According to this document,
http://download.oracle.com/docs/cd/B16240_01/doc/apirefs.102/e12639/chapter1.htm#CIAEFHFB
I see there are two cache system in Oracle BI Server, "Data Cache" and "Generic Cache".
What is the difference between these two kinds of cache ?
Thanks.

Hi user611881,
I'll try to explain the two cache types here, but if someone can better phrase it than myself, by all means, step up.
Data Cache:
The OBIEE BI Server will cache the result set of SQL that is executed. These cached results are records and if OBIEE sees another report requesting the same record set that it already has in cache, it will go straight to the cache version instead of re-issuing the SQL
Generic Cache:
The generic cache is the presentation server cache. This has to do with the caching of particular request. If the BI Server detects a cached version of a request, it will get the request directly from the cache and not even go down to check for the cached record set.
This is how they function. Assume you have report A with record set 1 and there's no data in either cache.
You run Report A
1) Presentation Service checks if the Request is in the generic cache.
2) This check fails.
3) Presentation service issues logical SQL query to BI Server
4) BI Server checks if there is any record set matching the logical query in the cache
5) This check fails.
6) BI Server issues the physical SQL
7) BI Server caches the result set
8) Presentation service gets result set and formats the data
9) Presentation service caches presentation results
10) Report A is displayed
That is my understanding of the Data and Generic Caches.
Good luck and if you found this post useful, please award points!
Best regards,
-Joe

Forms 9i and Generic Conectivity..

I've started doing my own business. I design and develop applications for small(mobil) businesses. An application runs on desktop. I have tried to use Forms 6i with a Sybase SQL Anywhere database and it works perfect.
My question is: How I can by an Oracle Forms and Generic Connectivity Solutions without anything else?
Does Oracle think about desktop and mobil user market?
To buy Developer Suite is very expensive. Or should I move toward Sybase Powerbuilder?
Thanks.
Vas

Vas,
actually Forms6i is the last client/server release of Forms, which means that starting Forms9i it only supports Web deployment. Forms6i client/server support (error correction) ends in end 2004 which means that after 2004 Forms is available on teh Web only. I can imagine that this is not the desktop strategy that you had in mind, but actually it is what the statement of direction on OTN says.
For mobile support, I think that you mean stand alone (laptop) based applications. Real mobile applications wont work using Forms because there is no certified technology for this right now.

Fran

Difference between fully-specified data types. and generic types

Hi,
Can anyone tell me the difference between fully-specified data types and generic types.
Thanks in advance.
Regards,
P.S.

HI
Generic table types
INDEX TABLE
For creating a generic table type with index access.
ANY TABLE
For creating a fully-generic table type.
Data types defined using generic types can currently only be used for field symbols and for interface parameters in procedures . The generic type INDEX TABLEincludes standard tables and sorted tables. These are the two table types for which index access is allowed. You cannot pass hashed tables to field symbols or interface parameters defined in this way. The generic type ANY TABLE can represent any table. You can pass tables of all three types to field symbols and interface parameters defined in this way. However, these field symbols and parameters will then only allow operations that are possible for all tables, that is, index operations are not allowed.
Fully-Specified Table Types
STANDARD TABLE or TABLE
For creating standard tables.
SORTED TABLE
For creating sorted tables.
HASHED TABLE
For creating hashed tables.
Fully-specified table types determine how the system will access the entries in the table in key operations. It uses a linear search for standard tables, a binary search for sorted tables, and a search using a hash algorithm for hashed tables.

Difference between Generic extraction and Generic Delta

Hi Experts,
Pleasee give of some information below query:
1) Difference between Generic extraction and Generic Delta.
2) How to achieve Generic delta.
3) When we go for Generic delta instead of generic extraction.
Advance ThankU. Points vl be assigned.
Thanks,
Ragu.R

Hi,
Generic delta is the delta load done using Generic DS.
Generic extraction
Usage:
1. When the standard extractors are not supporting the extraction what you need. If SAP does not have a standard extractor for your need to get data from R3, you would have to go for generic extractor.
2. If you create a custom object say by combining certain base tables in R3 say custom tables ZTAB1 and ZTAB2. These two tables are not SAP provided tables and there will not be any standard extractors. So cases like this you will have to go for generic extractors.
How:
You have to use RSO2 transaction and you can also set delta based on, one of the three characteristics such as timestamp, calday or pointer (a sequence no).
once you create it and activate it. The extractor will be available in ROOSOURCE - (table in R3 where all the data sources are available).

Differences between OIM Connectors using Adapter Factory and Generic Tech

Hi,
Can any one please tell me what is the difference between Oracle Identity Manager Connectors by using Adapter Factory and Generic Technology.
Regards,
Raghunath..

This issue is a bit complex but let me try to explain.
One way to look at it is to consider cars with automatic and manual gearboxes. A car with a manual gearbox requires more skills of the end user. You do need to understand how to use the clutch and what gear to use under what circumstances. In a car with an autoamtic gearbox all of these things are abstracted away from the user. On the other hand a automatic gearbox is more complex to manufacture, especially if you would do it yourself with just some machine tools and some basic materials available.
In the same way an adapter factory connector requires a bit more skill to install and configure. A generic tech one is a lot more point and click. The downside is that creating the generic tech takes a little bit more effort and skill.
Excellent article by Nishant on this : http://blog.talkingidentity.com/2007/06/understanding_oims_generic_tec.html
Hope this helps

Reflection and Generic Collections

Hi -
I'm having trouble with reflection on Sets
I have a set of type T extends U and want to return the class of T:
public static <T extends U> Class<T> getSetType(Set<T> set) {
// what to do?
}Any help?
Message was edited by:
[email protected]

parameterized types are not present at runtime, as danny basically indicated. what you want to do here is neither a generics nor a reflection issue: unless the Set is empty, you can just examine the first object it contains for it's class:
public static <T extends U> Class<T> getSetType(Set<T> set) {
     if ( null == set ) {
        return null;
     if ( 0 == set.size() ) {
        return null;
     return set.iterator().next().getClass();
}

Scjp preparation

Hi,
I am recently came to know that certification will plays a vital role in our career. Now I'm intereted in preparing for scjp. I know jdk 1.4 but not much 1.5. What is the suitable and helpful in future to take certification?
Is it compulsory to take training from sun like Java Programming Language (SL-275) and some other? I can't pay the additional amounts.
I'm practicing with javaranch roundup games and mock test papers and have books Complete Java 2 Certification Study Guide by Simon Robert, phillip heller n michale... and Sun Certified Programmer & Developer for Java 2 Study Guide by Kathy Sierra.
Is it right that exam simulators very useful. Can u give some free sites for it?
Please help me in getting information or any other suggesions for the preparation...
Thanks.... __Anand

What are the perfect SCJP preparations ?

well, I have some good experience with java SE and planning to take one of those SCJPs.
I'm really new to this, so please, would you advise me of what I should do??
How can I prepare for the exam ? and what books do you recommend to read...
Actually, I'm ready to study hard but I lack the good material ...so I would appreciate the help :)
another issue, we all know that scjp 6 has been released lately, so what do you recommend?
get the scjp 5 or 6?
of course this will affect the material I should read, too.
Thanks in advance :)

How can I prepare for the exam ? and what books do you recommend to read...If you already have several years of experience, study the language specification and make a lot of mock exams.
Revising the javadoc for especially the java.lang and java.util packages is a good idea as well.
And work your way through one of the seminal works about the exam, like Kathy Sierra and Bert Bates' masterwork.
While you may think you know a lot, that material will make you wonder how you got by all that time with such gaps in your knowledge about the language.
That is normal. Most people in their working life use only a relatively small portion of the entire platform.
Actually, I'm ready to study hard but I lack the good material ...so I would appreciate the help :)
Always good to see someone who wants to understand the material rather than cram for the exam.
another issue, we all know that scjp 6 has been released lately, so what do you recommend?
get the scjp 5 or 6?IMO the entire Java6 release should never have seen the light of day, but apart from that IMO one should go for either the exam that best fits with what one uses in ones work or with the very latest.
of course this will affect the material I should read, too.
Not that much I think. The differences in the core language are rather small, it's mainly the idiocy that was added like embedded database engines and webservers that make 6.0 different (and a disaster).
Might be difficult to get 6.0 exam materials btw.
