Performance Tuning :: Procedure Performance On New Database Import?
Nov 15, 2010Testing our 9i to 11g upgrade, we've imported the entire DB into the new machine.We've found that certain procedures are really suffering performance problems. BUT, we've also found, that if we check out a production copy of the procedure from our source code control, and reinstall it, the performance issue goes away. Just alter the procedure and recompiling does NOT work.
The new machine where the 11g database exists is slightly different than the source, but it's not like we have this problem with every procedure. It's only a couple.
any possible reason that we'd have to re-install a procedure to correct a performance problem?

Jul 12, 2010Looking to understand the difference between instance tuning and database tuning.
What is the difference between these two tuning exercises? I understand that an instance is memory based structures (logical) where as database consists of physical structures.
However, how does one tune a database the physical structure? Does it have to do with file placements/block sizes etc. Would you agree that a lot of that is taken care by ASM now in 11g? What tools are required/available (third party as well as oracle supplied) for these types of tuning scenarios?

Export/Import/SQL Loader :: Migrate Database Into Different SID
Jul 19, 2012I need to migrate a 10g database into an 11gR2 on same Red Hat Linux platform (although different servers with different versions of Linux). The difference between the two databases however is the SID, the new one has a different SID which means that the datafiles will be named differently (as our datafile names include the SID) otherwise everything else is the same..
I propose to take the following steps:
- install 11gR2 on the new server
- create the 11gR2 database with new SID using DBCA
- full export 10g database
- full import dump file into 11gR2 database.
I however do not have experience of how this will work with respect to the full import where the datafiles are named differently. For example TABLESPACE TEST in the source database has datafile TEST_SOURCE.dbf but the same TABLESPACE TEST in the target database will have datafile TEST_TARGET.dbf.
Will all the data in the source database be correctly imported into the new database?

Export/Import/SQL Loader :: Perform Full Exp / Imp Of Oracle 11g Database?
Jul 30, 2012i want to perform full export + import of an oracle 11g database as fast as possible. i was thinking to perform the exp+imp on the same command.in exp i can perform something like this :
mknod /oracle/migration/exp_pipe p
exp '/ AS SYSDBA' file= /oracle/migration/exp_pipe full=y | imp system/***@oracle_db file= /oracle/migration/exp_pipe full=y
i know that i can do both action in impdp when using a dblink, but the problem is that some objects in the database cannot be copied via a dblink. the question is if there's a corresponding datapump command to the old exp+imp command i presented.
Export/Import/SQL Loader :: Copy Data From Oracle Database To Another?
Jun 6, 2013I want to Copy a data from One oracle database to another.
I have checked Import/Export Utility but the problem is import utility doesn't support conflicts resolution techniques between rows.
For Example if there's a table in the source database have the same row key in the destination database. if i use 'Ignore' parameter with value = y, the destination table will have a duplicate rows.
I want to ask if there's another way to import data from oracle database to another with some mechanism of detecting the conflicts and resolve them?
Export/Import/SQL Loader :: Oracle Database 10g - Format For Control File
Jan 28, 2013I'm studying abt SQL*Loader. All I've learn it needs to have:
1. One text input file
2.Control file
3.Bad file...
But I'm confused where to put the input file...where to put the control file in which format and in control file what should I write...
My oracle version is:
Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - Prod
PL/SQL Release 10.2.0.3.0 - Production
CORE 10.2.0.3.0 Production
TNS for 32-bit Windows: Version 10.2.0.3.0 - Production

Export/Import/SQL Loader :: Using Datapump On Windows Client When Database Is On Linux
Jun 13, 2013the database (11gR2) is located on Linux server. A business application is installed on a Windows server with an Oracle client 11g.The application is able to start a datapump export, but as matter of fact the dumpfiles are always written to the Linux-server. The directoryobject is defined as DATA_PUMP_DIR (which is the default directory).
Now we are supposed to change the datapump export in a matterthat the dumpfiles get written to the Windows server. Creating a new directory (e.g. c:datapump) and starting than the datapump from theclient always raises the errors
ORA-39002: ...ORA-39070: ...ORA-29283: ...ORA-06512: in "SYS.UTL_FILE", Zeile 536ORA-29283: ...
Is it possible at all to start a datapump export from a Windows client and writing the dumpfiles to the Windows server itself? Or do the dumpfiles always written to the database-server?
Export/Import/SQL Loader :: Upgrading 9i Database To 11g That Supports 3rd Party Software
Apr 30, 2013Upgrading one of the 9i database to 11g that supports a 3rd party software - ***Vendor provided an over-simplified documentations*** and recommends moving from 9i to 10g before going to 11g. A few changes from 9i to 10g.
1) db_block_size
2) character sets
etc.
Anyway, created the database DBUPGTEST on 10.2.0.1 (ultimately moving to 11gR2, so no point patching to 10.2.0.5, is there?) with all the parameter changes. At this point, these are the 2 db in play:
Current production db: Oracle 9i - PROD dbname => 2048K db block size
Current migrating db to: Oracle10g - DBUPGTEST dbname => 8192k db block size
Steps
According to vendor notes / documentation,
1) create db
2) exp full from 9i
3) imp full to 10g
Problems
1) import ended with completed unsuccessful.
2) user accounts are imported (because their default tablespace is USERS - which had already been created during DB creation); but, user accounts (schema accounts) with a different default tablespace are not imported.
Looking at the imp.log - seems like it's complaining about the db_block_size during tablespace creation - which explains why the schema accounts are not imported; because the tablespace was not created.
My questions
1) How do I import to 10g? Can I create all the tablespace in 10g first? Then import? Will it crap out because it already exists? Or will it import the objects in the schema?
2) How do I refresh data from PROD? Remember this is 9i and most of the expdp functionalities are not available. And I cannot re-exp and re-imp because there are steps (sql to run) after moving to 10g to fix some software upgrade table mappings. If I re-exp from 9i and re-imp to 10g, won't I have to re-run all those steps before the apps will run?
