Urgent:cvs and database

hi,
I'm not sure how i'm supposed to retrieve data from a csv file and enter it into an oracle database. The database is accessed via JDBC and servlet. If anyone has any ideas please let me know.
Thanks
Jeena

There is a csv-parser as an example in the following book:
Brian W. Kernighan, Rob Pike:
The Practice of Programming
http://www.aw.com/catalog/academic/product/1,4096,020161586X,00.html
The book is written in English, the example in C.
You can even download the source from some URL which I do not know by heart.

Working With CVS and JDeveloper 10.1.2 URGENT

Hi Guys,
Can somebody help me out? To work in Team Development we have chosen CVS. I have two versions CVSNT, 2.5.02 and 1.11.13. I have followed every step from the help file, and installed them (first 2.5.02 and then 1.11.13, after un-installing 2.5.02). Now whenever I click CVS Server node from the Connection tab, it always display a message Alert:
The CVS executable is not installed or not located in your system environment path.
although I have added the path in the path variable.
I was going through the article:
Oracle� JDeveloper 10g
Installation Guide
Version 10.1.2
October 2004
where it recomended the CVS version:
Concurrent Version Support (CVS)
* CVS versions 1.10 to 1.11.14
* CVSNT versions 2.0.26 to 2.0.34
If I download the following version, won't I get any error message? If so, then where can I find the versions?
Any help will be appriciated and thank you in advance.

hello i am using
cvs --version
Concurrent Versions System (CVSNT) 2.5.02 (Servalan) Build 2064 (client/server)
that i download from cvsnt.org
cvs it's in path variable.
and front-end i use Tortoise CVS that is better because it's integrated in Windows Explorer.
otherwise in JDev select menu Versioning->Select System-> check CVS and then
in tab Connections in CVSServer right click and select new cvs connection.
configure and work.
try to have only a cvs.exe in your machine.
i want help you.

Jheadstart, JDeveloper and CVS and TeamWork

Hi
We're four-developer team and we've been working with Jheadstart for some months. Now we want to work with team options that provide jdeveloper (CVS or SCM). But, we are a too much suprised with all the problems that other developers had with CVS, we read it in some jdeveloper forums (JDeveloper and CVS and TeamWork and JDeveloper and CVS
I get very worry about the problems that developers had with CVS and that at last they don't find a better solution than migrate to jdeveloper 10.1.3. All the forums recomend migrate to jdeveloper 10.1.3 for better support of team work, but I read (some time ago) that jdeveloper 10.1.3 still doesn't support ADF, then I assume we cannot use it with Jheadstart, Am I right? Is there a way to use Jheadstart with JDeveloper 10.1.3 Preview right now?
What do you recomend for team work with Jheadstart?
Thanks in advance
Liceth

Liceth,
As you problably know, the JHeadstart team consists of consultants and we face the exact same problems and share the exact same frustrations as you do on an every day basis at our customer projects. It is indeed not easy to use JDeveloper in a multi-developer environment. In all fairness much of this is a given when doing file-based development, and I have seen the exact same problems in situations where other IDE's such as Eclipse etc were used. But using advanced frameworks like ADF and BC4J makes matters more complex, because the declarative way of developing these applications using drag&drop and powerful wizards make you as a developer be less 'in touch' with the file or files that are actually created and updated, and also there tend to be more files in such an architecture that are changed simultaneously by many developers at once.
Merging is the only way out of this mess, and merge tools are not perfect, far from it. They get better and better but at some point you'll need to understand the semantics of the files that are to be merged to be able to merge them correctly, and merge tools will in all likelyhood never become that smart.
Until they do, the only thing one can do is to tackle the problem from the other side: if merge tools dont understand the files they merge, we should take into account the weaknesses of these merge tools, and set up our files so that changes CAN be automatically merged, or in most cases at least. Indeed, JDeveloper 10.1.3 is taking good steps in this direction for notoriously tricky files such as JPR files and such. But the problem will never completely go away.
As for using 10.1.3, well, as you said the preview does not contain ADF so JHeadstart will never run on it. We are developing JHeadstart 10.1.3 that will run on the production version of JDeveloper 10.1.3, but it will be a long time before that release will see the light. And although JDeveloper 10.1.3 is a kick-ass IDE (imho), it will not magically solve all multi-user issues. It will just be a bit more bearable.
Is there ever a real solution for it? I don't know. I have worked intensively with the Oracle Designer product before I switched to Java, and that tool, which uses a database rather than files to store its information, was almost perfect when dealing with multi-user development. It could do so because the level at which conflicts occur is VERY finegrained (so not at 'code line' level but sometimes as far as 'individual properties in a property inspector' level), plus the advantages of instantaneous locking in the database when modifying something. And, thinking of it, it could do so because it dealt with 'structured objects' rather than files, thereby having some 'semantic' information about the data. I have this feeling we can only 'get it right' if we will treat, for instance, a Java file not as a collection of lines of code, but of a structured object tree with members, constructors, methods, parameters etc. etc., and store it as such, instead of storing it as a flat OS file.
Just ranting here (this really should be a personal BLOG entry rather than a forum post, but oh well). As you can tell, its a subject that is very close to every developer's heart.
Kind regards,

Re: what is difference between sap locking and database locking

hi,
    what is difference between sap locking and database locking. Iam locked the table mara by using lock objects.
But iam unable to unlock the mara table. I give u the coding. Please check it.

Hi Paluri
Here is the difference between SAP locks and Database locks, i will try to find the solution to your code.
Regards
Ashish
Database Locks: The database system automatically sets database locks when it receives change statements (INSERT, UPDATE, MODIFY, DELETE) from a program. Database locks are physical locks on the database entries affected by these statements. You can only set a lock for an existing database entry, since the lock mechanism uses a lock flag in the entry. These flags are automatically deleted in each database commit. This means that database locks can never be set for longer than a single database LUW; in other words, a single dialog step in an R/3 application program.
Physical locks in the database system are therefore insufficient for the requirements of an R/3 transaction. Locks in the R/3 System must remain set for the duration of a whole SAP LUW, that is, over several dialog steps. They must also be capable of being handled by different work processes and even different application servers. Consequently, each lock must apply on all servers in that R/3 System.
SAP Locks:
To complement the SAP LUW concept, in which bundled database changes are made in a single database LUW, the R/3 System also contains a lock mechanism, fully independent of database locks, that allows you to set a lock that spans several dialog steps. These locks are known as SAP locks.
The SAP lock concept is based on lock objects. Lock objects allow you to set an SAP lock for an entire application object. An application object consists of one or more entries in a database table, or entries from more than one database table that are linked using foreign key relationships.
Before you can set an SAP lock in an ABAP program, you must first create a lock object in the ABAP Dictionary.

Some error in cluster alertlog but the cluster and database is normal used.

hi.everybody
i used RAC+ASM,RAC have two nodes and ASM have 3 group(+DATA,+CRS,+FRA),database is 11gR2,ASM used ASMlib,not raw.
When i start cluster or auto start after reboot the OS,in the cluster alertlog have some error as follow:

I do not know what cause these error but the cluster and database can start normal and use normal.
I do not know whether these errors will affect the service.
thanks everybody！

Performance with MySQL and Database connectivity toolbox

Hi!
I'm having quite some problems with the performance of MySQL and Database connectivity toolbox. However, I'm very happy with the ease of using database connectivity toolbox. The background is:
I have 61 variables (ints and floats) which I would like to save in the MySQL-database. This is no problem, however, the loop time increases from 8ms to 50ms when using the database. I have concluded that it has to do with the DB Tools Insert Data.vi and I think that I have some kind of performance issue with this VI. The CPU never reach more the 15% of its maximum performance. I use a default setup and connect through ODBC.
My questions are:
1. I would like to save 61 variables each 8-10ms, is this impossible using this solution?
2. Is there any way of increasing the performance of the DB Tools Insert Data.vi or use any other VI?
3. Is there any way of adjusting the MySQL setup to achieve better performance?
Thank you very much for your time.
Regards,
Mattias

First of all, thank you very much for your time. All of you have been really good support to me.
>> Is your database on a different computer? Does your loop execute 61 times?
Database is on the same computer as the MySQL server.
The loop saves 61 values at once to the database, in one SQL-statement.
I have now added the front panel and block diagram for my test-VI. I have implemented the queue system and separate loops for producer and consumer. However, since the queue is building up faster then the consumer loop consumes values, the queue is building up quite fast and the disc starts working.
The test database table that I add data to is created by a simple:
create table test(aa int, bb char(15));
...I'm sure that this can be improved in some way.
I always open and close the connection to the database "outside the loop". However, it still takes some 40-50 ms to save the data to the database table - so, unfortunatly no progress to far. I currently just want to save the data.
Any more advise will be gratefully accepted.
Regards,
Mattias

I just want itunes music and database to be on external HD not internal

What am I doing wrong. I have itunes music library on my external HD and my itunes preferences say that my itunes music folder location is just that. It's about 41 GB. Ok, but why on my system drive is there an itunes folder in the default user music folder and it is 7 GB and there are certain titles in there that did not make it to the external. The database files are in there as well. Shouldn't everything be located in the external itunes music folder including the database files ? How do I have itunes automatically update the external HD folder and put the database files in there as well and stop using the internal system drive for storage and database.

I did that a while ago. But now it seems there are 7 GB of stray files. Is there a sync feature that moves only the itunes files that are outside the designated itunes folder, in my case they are living on the system drive for some reason...

I run Dev 6i on Windows 2008 R2 64-bit,the forms are working fine after connection to the database but the reports continue to request for username, password and database connection string every time i try to open a report.

I receive REP-0501: Unable to connect to specified database. I run developer 6i application on windows 2008 r2. I have applied the nn60.dll and nnb60.dll files to the \BIN directory. The forms are working fine. The reports will only display after the correct user id (username, password and database connection string) is supplied. This is happening to all attempts to open already complied form. Pls, help.

If you are connecting to an Oracle 11g database, remember that by default the passwords are case sensitive. To disable that, run
ALTER SYSTEM SET SEC_CASE_SENSITIVE_LOGON = FALSE;

Hi
I faced this issue before ,Reinstall is the option you have .Verify the version of RCU before you start creating schema .Set all Pre DB setting ,hostname and IP Address ,If DB and OIM are in ifferent machines check pinging from both the sides .
Please Drop all OLD schema ,Create a New "Prefix" for fresh installation , don't use old schema .
Let me know .
Thanks,
Ari

TA25361 I have a ton of documents and databases in AppleWorks v 6.0 that I can no longer open on my MacBook Pro. Is there any way to recover this info? Some documents can be opened and resaved with textedit, but not my database with all important addres

I have a ton of documents and databases in AppleWorks v 6.0 that I can no longer open on my MacBook Pro. Is there any way to recover this info? Some documents can be opened and resaved with textedit, but not my database with all important addresses.

I tried Peggy's List > Select All > Copy > Paste into an AW spreadsheet suggestion.
In my case, pasting into the spreadsheet lost all text formatting (mostly text set to bold). The results of formulas were pasted, and checkboxes were pasted as "on" or "off". The DB did not contain any pop-up menus or radio buttons, but I expect they would transfer as a number showing the list position of the chosen item.
Pasting the copied List view data into a Numbers table gave a result similar to that with AppleWorks. I selected B2 as the target cell (for top left cell of the pasted data) to avoid any effects of posting into a header row or column. Bold and regular text formatting looked the same as it had in AW's List view.
Based on that, I'd slip the 'paste into an AppleWorks Spreadsheet step, and paste directly into a Numbers Table.

Barry

Is the only way to import large amount of data and database objects into a primary database is to shutdown the standby, turn off archive log mode, do the import, then rebuild the standby?

I have a primary database that need to import large amount of data and database objects. 1.) Do I shutdown the standby? 2.) Turn off archive log mode? 3.) Perform the import? 4.) Rebuild the standby? or is there a better way or best practice?

Instead of rebuilding the (whole) standby, you take an incremental (from SCN) backup from the Primary and restore it on the Standby. That way, if, for example
a. Only two out of 12 tablespaces are affected by the import, the incremental backup would effectively be only the blocks changed in those two tablespaces (and some other changes in system and undo) {provided that there are no other changes in the other ten tablespaces}
b. if the size of the import is only 15% of the database, the incremental backup to restore to the standby is small

SQL script based on hostname and database name?

I am trying to write a script that I can run on several unix servers and databases that will do different sql statements based on which server and database it is being run in.
Something like:
if hostname = 'A' and database name = 'D' then do this
else if hostname = 'B' and database name = 'F' then do that
I have tried many diifferent combinations of shell scripts and sql scripts but can't seem to get anything that works.
Can someone help me out? Thanks.

Since you are already able to get he db and host info, you are well on your way to branching based on that information. All you need is the basic framework:
declare
db VARCHAR2(30);
host VARCHAR2(30);
sqlcmd VARCHAR2(4000);
begin
select sys_context('userenv','host') host
       , sys_context('userenv','db_name') db_name
    into host
       , db
    from dual;
case
    when db = 'XE' and host = 'mypc' then
      sqlcmd := q'[local_package.do_something('parm1', :db, :host)]';
      execute IMMEDIATE sqlcmd USING db, host;
    when db = 'DEV' and host in ('serv1','serv2') then
      sqlcmd := q'[different_packge.do_something('parm1', :db, :host)]';
      execute IMMEDIATE sqlcmd USING db, host;
    else
      dbms_output.put_line('unrecognized db/host combination: '||db||', '||host);
end case;
end;
/In this example I've used dynamic SQL since not all instances are guaranteed to have any or all of the package procedures referenced in the dynamic sql. With out the dynamic sql, you would get errors and be unable to run the script on any instance lacking one or more of the reference package procedures..

Different values on form and database

hi all
i have a field which counts the number of rows
on the form which is showing a different value (which is correct)
and in the database it is showing a different value (incorrect)
i have issued commit
i am not understanding why this is happening ..
please help me
Mandar

listening for the first time but u r facing the problem, reconfirm that the query/properties are correct in form properties, check it by creating new form module for just checking weather it is showing correct in that form. and c if there is when_new_form_instance trigger or When_Validate_windows trigger used for some execution. and one more thing just check if u didnt change the column and create it again and database type is NO ( properties )
