How to tune a package

Hi,
I have 5 Packages and each package has more than 3500 rows. I want to tune package. How many ways I can tune. Is there any process to tune package. Please help me to solve this.

< dont have privilages to use Sys user>
you don't need to be SYS to use DBMS_PROFILER. SYS needs to install it, so that's a DBA job. Once its installed you need EXECUTE privilege on the package (another DBA job) and you can use it once you create the source tables in your schema; Oracle provides a script for that with the Oracle installation.

How to tune "Buffer Get" offender

QUESTION: How to tune following sql
SELECT *
FROM trans
WHERE accountid = NVL (NULL, accountid)
AND transtypeid = 171
AND NVL (description, '-1') = NVL ('Card Activation Fee ', '-1')
AND ABS (transamt) = ABS (9.95)
AND accountid <> 7689966
AND postdate BETWEEN ( TO_DATE ('03/14/2006 00:17:43',
'mm/dd/yyyy hh24:mi:ss'
- .00011574
AND ( TO_DATE ('03/14/2006 00:17:53',
'mm/dd/yyyy hh24:mi:ss'
+ .00011574
DETAILS:
Statspack has shown this piece of SQL as the largest contender for "Buffer Gets" chewing up 513.28 seconds of CPU time out of 3,475 (See Top 5 Timed Events below)
However, when I run the sql statement by itself in TOAD, it takes 90ms to complete and has a cost of 202 (See plan below). TRANS table has over 18m rows.
Operation     Object Name     Rows     Bytes     Cost     Object Node     In/Out     PStart     PStop
SELECT STATEMENT Optimizer Mode=CHOOSE          1           202
TABLE ACCESS BY INDEX ROWID     SVOLTP.TRANS     1      65      202
INDEX RANGE SCAN     SVOLTP.TRANS_POSTDATE_NIDX     1 K          7
Top 5 Timed Events
~~~~~~~~~~~~~~~~~~ % Total

db file parallel write 3,983 49 .70

here is the actual statement taken from the package:
select transid
into lFromTransID
from trans
where accountid = nvl(lacctid, accountid)
and transtypeid = lToTrans.transtypeid
and nvl(description, '-1') = nvl(lToTrans.description, '-1')
and abs(transamt) = abs(lToTrans.transamt)
and accountid <> lToTrans.accountid
-- Transactions must be posted within 10 seconds of each other
and postdate between (lToTrans.postdate - .00011574) and (lToTrans.postdate + .00011574);

How could I transport package with all content within

How could I transport package with all content ( I do not get it with se80->"write transport entry") or by entering in se10 in transport request object R3TR DEVC.

go to SE03
choose the third item "include objects in a request" by double-clicking
there you set the first parameter "Package" to your package and execute
note: you can also deselect the radiobutton "All objects" and set "Selected objects" then you will be able to fine-tune the list of objects

What do you mean? Something like SELECT mypackage.function( par1, par2) from dual?

How to open a package body in Oracle sql developer

How to open a package body in Oracle sql developer..any shortcut for that

I need another way to get to my package body. I'm on a locked down system, so the only way I can reference anything is if I already know the name of it. I accidentally overwrote my text document that I was using to work on it and I closed out of the package body in sqldeveloper. There must be a command, like an alter or some such. Anyone know the old fashioned way of looking at a package?

If many full table scans on big tables consider creating indexes. Or if many index reads consider forcing full table scans :)
Ah, I just love these tuning questions. "My query is slow. Please make it go fast". Sure, put on these red shoes, click your heels three times and make a wish. Alas, tuning is rather more complicated than that, more of a science than a voodoo rirtual. We would like to help. But we need more data, some concrete figures. Otherwise we're just guessing.
So, first off, please read the Performance Tuning Guide. Apply some of its techniques. If you still don't understand why your query is running slow, come back to us with table descriptions, volumetrics, indexes, explain plans, stats, timings and tkprof output.
Good luck, APC

How to remove a package from package structure?

Hello profs,
i have a problem. I add a package 'A' to another package 'B' in the package builder.
Now i don't know how to remove package 'A' from the list of package 'B'.
I have not found in the docu of package builder how to remove a package from the included list.
Has somebody an idea how to do it?
Thanks a lot.

I found out that the relation between the packages saved in table TDEVC.
Field PARENTCL contains the surrounding package 'B' of the package 'A' field DEVCLASS.
At the moment the only way to remove the package is to modify the table.
But i look for another possibility for this issue.
Best regards
Waldemar

Thanks, David. I know this workaround. And one more with creating right-click Service. That's why I've used "uncomfortable" instead of "impossible". In my opinion, Apple should leave ability to choose OS's behavior, and I hoped somebody knew where to find it .

How to Execute SSIS package through MySQL Procedure

Hi Everyone,
How to Execute SSIS package from MySQL Stored Procedure.
Please share your suggestions on this.
Regards,
Vaishu

I am not sure whether you have SSIS license version installed in the system where MYSQL is there. In order to run SSIS package we need to have DTEXEC executable file and it comes with SSIS license version.
An SSIS package can be executed from command prompt as,
C:\>dtexec /f E:\package.dtsx
I am not expert in MYSQL however in TSQL we can run dos command or scripting language such as vbscript.
Similarly you need to check in MYSQL. This is MSSQL Server forum.

How to create a package and add a file?

Hi all,
I am new to Java and very much much confussed with how to create a package and then include some files any help will be very thankfull.
Thanks for your help
kka.

Steps for creating a package in java are as follows:
Choose a base directory for your classes. For example, you might choose c:\java\packages. Type the following command:
set CLASSPATH=%CLASSPATH%;c:\java\packages
Create subdirectories for each chapter or section, if you don't already have them.
For each of the classes in the subdirectories, add the following line to the very top of each file:
package directory-name;
where directory-name is the name of the subdirectory the class file is located in.
In other directories you may have class files that need to access one of the classes in another directory (package). To do this, write one of the following at the top of the class that needs the other class:
import subdir.*;
or
import subdir.classname;
Use the class by name in the new class file.
Note that you can create sub-packages by creating subdirectories of the original subdirectories, and inserting package statements at the top of the java files in those directories.
Hope this helps!

Hi
Since this is a Std Package and the IW37N is a Std transaction, it should by default will come along with the std software?
Which version of SAP are you working?
In ECC6.0 it is there? may be you are working in Lower version of SAP?
Chek whether IW37 is there or not? I think it will be there.
Check with the Basis person for this..
