=================================================
Learning how to look things up in the documentation is time well spent investing in your career. To that end, you should drop everything else you are doing and do the following:
Go to tahiti.oracle.com.
Locate the link for your Oracle product and version, and click on it.
You are now at the entire documentation set for your selected Oracle product and version.
BOOKMARK THAT LOCATION
Spend a few minutes just getting familiar with what is available here. Take special note of the "books" and "search" tabs. Under the "books" tab (for 10.x) or the "Master Book List" link (for 11.x) you will find the complete documentation library.
Spend a few minutes just getting familiar with what kind of documentation is available there by simply browsing the titles under the "Books" tab.
Open the Reference Manual and spend a few minutes looking through the table of contents to get familiar with what kind of information is available there.
Do the same with the SQL Reference Manual.
Do the same with the Utilities manual.
You don't have to read the above in depth. They are reference manuals. Just get familiar with what is there to be referenced. Ninety percent of the questions asked on this forum can be answered in less than 5 minutes by simply searching one of the above manuals.
Then set yourself a plan to dig deeper.
- *Read a chapter a day from the Concepts Manual*.
- Take a look in your alert log. One of the first things listed at startup is the initialization parms with non-default values. Read up on each one of them (listed in your alert log) in the Reference Manual.
- Take a look at your listener.ora, tnsnames.ora, and sqlnet.ora files. Go to the Network Administrators manual and read up on everything you see in those files.
- *When you have finished reading the Concepts Manual, do it again*.

Migrating Analyzer Objects to New Server

How are Analyzer objects migrated from a source server to a target server? I am anticpating the creation of various environments (DEV, TEST, PROD) and will need to port Analyzer objects among these environments in support of our releases. It is likely that all Analyzer environments will contain the same version (currently 6.5.1). Will relational repository tables also need to be ported separately, or do the Analyzer import/export utilities take care of everything?Thanks, in advance....

The best way migrating analyzer objects is ,install analyzer in where you want and copy the data from one production(repository )to the Test(other)That want you no need to migrate every report/group which is tedious process.Ram

Rollback after analyze command

Hi Everyone,
My DB version is
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bi
PL/SQL Release 10.2.0.1.0 - Production
"CORE    10.2.0.1.0    Production"
TNS for Linux: Version 10.2.0.1.0 - Production
NLSRTL Version 10.2.0.1.0 - Production
I've inserted 5 rows in a table, but didn't commit the transaction.
After that I executed following query to update the plan table.
analyze table <table_name> compute statistics
Then I query the plan table for the update, it's updated, but after that I rolled back the transaction
and was hoping that those 5 records will be deleted from that table as I didn't commit the transaction.
But that didn't happen. So my question is when I was computed the statistics, previous DML statement
is committed automatically or what happened? Why ROLLBACK is not working for that table?
Regards,
BS2012.

I tried this in Oracle 11gr2 version and found similar characteristic.
CREATE TABLE tmp (nm VARCHAR2 (100));
Table created.
INSERT INTO tmp
     VALUES ('A');
1 row created.
INSERT INTO tmp
     VALUES ('B');
1 row created.
INSERT INTO tmp
     VALUES ('C');
1 row created.
INSERT INTO tmp
     VALUES ('D');
1 row created.
INSERT INTO tmp
     VALUES ('E');
1 row created.
ANALYZE TABLE tmp COMPUTE STATISTICS;
Table analyzed.
ROLLBACK;
Rollback complete.
SELECT COUNT (*) FROM tmp;
count(*)
5
According to documentation:
COMPUTE STATISTICS instructs Oracle Database to compute exact statistics about the analyzed object and store them in the data dictionary. When you analyze a table, both table and column statistics are collected.
So Analyze is basically doing a commit into data dictinary in the same session.
Probably that is the reason why rollback does not work here.
Its like simple example:
I inserted 100 rows in a table without commit;
Created a new table in same session (DDL implicit commit)
rollback;
-- that rollback will not have effect on the 100 rows we committed before.
I guess Gurus will come up with better examples than what I have elucidated.

Manik.

Transportation of Objects from BW3.5 to 7.0 possible?

Hello,
our customer uses our Bank-Analyzer (for Basel II) and BI in NW04s for the data supply of the mentioned BA.
The basis for the Bank Analyzer is also BW technology, something called "Tool BW", which has version BW 3.5 for the current BA Version 5.0.
After connecting BW to the Bank Analyzer a Metadata-Exchange is necessary to use the same Metadata in BW and Bank-Analyzer (mainly same InfoObjects). This usually be done by transport.
Now the question is:
We are using BI7 for the supplying BW and the BA 5.0 based on BW 3.5. Can I transport Object catalogues and InfoObjects from BW7 to BW3.5?
Thanks
Thomas

How certain are you with your answer? The reason for ckecking back is, that both version (BI and Bank Analyzer) are together part of our RampUp and are supposed to work together. And if you are now saying transports from 7.0 to 3.5 are not possible this would mean that all Bank Analyzer objects (delivered by SAP or manually created in addition) had to be recreated manually in BW.
Thanks! Thomas

Are you trying to analyze objects that do not belong to the user performing the analyze? If so, that user would need the ANALYZE ANY system privilege. Depending on your organizations policies it might be better to have each user analyze their own objects instead of granting the ANALYZE ANY privilege to a user.

What will happened when analyze a table

Hi all,
Can any one explain ,when analyze objects what will happend internally.
Thanks in advance,

If it's the "gather statistics" option then you probably shouldn't be using it and probably don't need to know.Database Version Oracle 9.2 and 10.2
Analyze table SCOTT.EMPLOYEES extimate statistics;
EXEC DBMS_STATS.gather_table_stats('SCOTT', 'EMPLOYEES');For 9.2 and 10.2 you should be using the dbms_stats package to collect statistics. It's what the optimizer is expecting, and since the numbers collected by analyze and dbms_stats are not consistent with each other it's what you should use (unless specifically directed otherwise by an application supplier).
As far as "what happens when you use dbms_stats to gather statistics for a table" - one of the other posters has given you the overview, if you want specific details than check the PL/SQL supplied procedures manual, and the Performance Tuning guides.

DBAShell - New Open Source Project for Oracle DBA's

I'd like to have this project included in the Open Source Oracle tools list at: http://www.oracle.com/technology/community/opensource_projects.html
I've been an Oracle DBA for quite some time (since 7.0.13) and a developer for many years. One of the things I've always wished for was an easier way to set up environment variables for different Oracle Homes and a way to provide passwords to scripts without embedding them in plain-view.
About 3 years ago, I started a set of functions and scripts at my company that did exactly just that and provided many more functions for things like checking database status, running scripts quietly unless errors are detected, running actions in parallel (like fast shutdowns at once, or multiple analyzes), restarting databases in a guaranteed fashion, aliases to common folder locations, etc..
About a month ago, after putting all this time and effort into these scripts and using them in production all this time, I realized I wanted more out of the scripts like support for other databases and thought that it would be best if I gave it new life as an Open Source project.
So that is how http://sourceforge.net/projects/dbashell/ was started. Now its in a second release (DBAShell 0.85) that is more modular and would allow other people to easily add support for other OSs, other Shells, and other Databases.
Here is a description of the project from the latest news item:
DBAShell is a project based around Shell functions and scripts designed to make it easy for DBA's to use Databases in a command line environment. Currently supported is Oracle with ksh and bash on AIX, Solaris, Linux. The code base itself is 3 years old and has been in use in Production environments all of that time.
Features include:
* Automatic setting of all environment variables based on SID requested.
* Manage PATH's and other path like variables for each ORACLE_HOME needed.
* Run scripts with stored passwords (no more hard-coding of passwords!!)
* Automatically set SID based on Script location (makes it easier to share scripts between SID's)
* manage temporary script output and check for oracle errors in output
* check database status and versions from scripts
* stop/start databases in parallel (faster startup)
* compile all database objects
* analyze objects in parallel (Faster analyzes)
* set aliases and variables for common SID areas, etc..
* many helpful commands for common Oracle tasks
Over a thousand people have already downloaded the prior release and more are downloading every hour.
I'm seeking feedback from anybody that would be willing to take a look at the project, trying it out, give me any feedback you have on it, and perhaps even direct me to where I could best promote this project.
I wrote a tutorial that shows at a glance some of the more useful features of DBAShell:

Using export/import to migrate data from 8i to 9i

We are trying to migrate all data from 8i database to 9i database. We plan to migrate the data using export/import utility so that we can have the current 8i database intact. And also the 8i and 9i database will reside on the same machine. Our 8i database size is around 300GB.
We plan to follow below steps :
Export data from 8i
Install 9i
Create tablespaces
Create schema and tables
create user (user used for exporting data)
Import data in 9i
Please let me know if below par file is correct for the export :
BUFFER=560000
COMPRESS=y
CONSISTENT=y
CONSTRAINTS=y
DIRECT=y
FEEDBACK=1000
FILE=dat1.dmp, dat2.dmp, dat3.dmp (more filenames here)

I recommend you to change some parameters and remove
others:
BUFFER=560000
COMPRESS=y -- This will increase better storage
structure ( It is good )
CONSISTENT=y
CONSTRAINTS=y
DIRECT=n -- if you set that parameter in yes you
can have problems with some objects
FEEDBACK=1000
FILE=dat1.dmp, dat2.dmp, dat3.dmp (more filenames here)
FILESIZE=2048GB
FULL=y
GRANTS=y -- this value is the default ( It is
not necesary )
INDEXES=y
LOG=export.log
OBJECT_CONSISTENT=y -- ( start the database in restrict
mode and do not set this param )
PARFILE=exp.par
ROWS=y
STATISTICS=ESTIMATE -- this value is the default ( It is
not necesary )
TRIGGERS=y -- this value is the default ( It is
not necesary )
TTS_FULL_CHECK=TRUE
you can see what parameters are not needed if you apply
this command:

Table not returning correct information

We had a problem where doing a select count(*) returned a number, but then when a select * was issued not rows were returned. Many iterations were tried. Some returning rows and others not. Then when trying to truncate FK errors occurred. Does anyone know what might have been the problem? Our solution was to drop and re-create the tables. This was in a test environment, but we don't want this to happen in production.
Thanks.

Something doesn't sound right to me. I haven't seen this happen in our Oracle databases but have seen this happen with a DB2 database
when an index was corrupt. The solution was to rebuild the index in that case. I'd issue a statement to validate the structure of the table
and its indexes:
analyze table table_name validate structure cascade;
From the 8.1.7 SQL manual:
VALIDATE STRUCTURE
Specify VALIDATE STRUCTURE to validate the structure of the analyzed object. The statistics collected by this clause are not used by the Oracle optimizer, as are
statistics collected by the COMPUTE STATISTICS and ESTIMATE STATISTICS clauses.
For a table, Oracle verifies the integrity of each of the table's data blocks and rows.
For a cluster, Oracle automatically validates the structure of the cluster's tables.
For a partitioned table, Oracle also verifies that each row belongs to the correct partition. If a row does not collate correctly, its rowid is inserted into the
INVALID_ROWS table.
For a temporary table, Oracle validates the structure of the table and its indexes during the current session.
For an index, Oracle verifies the integrity of each data block in the index and checks for block corruption. This clause does not confirm that each row in the table
has an index entry or that each index entry points to a row in the table. You can perform these operations by validating the structure of the table with the
CASCADE clause (described below).
Oracle stores statistics about the index in the data dictionary views INDEX_STATS and INDEX_HISTOGRAM.
See Also: Oracle8i Reference for information on these views
Validating the structure of an object prevents SELECT, INSERT, UPDATE, and DELETE statements from concurrently accessing the object. Therefore, do not use this
clause on the tables, clusters, and indexes of your production applications during periods of high database activity.
If Oracle encounters corruption in the structure of the object, an error message is returned to you. In this case, drop and re-create the object.
INTO table
Specify a table into which Oracle lists the rowids of the partitions whose rows do not collate correctly. If you omit schema, Oracle assumes the list is in
your own schema. If you omit this clause altogether, Oracle assumes that the table is named INVALID_ROWS. The SQL script used to create this table
is UTLVALID.SQL.
CASCADE
Specify CASCADE if you want Oracle to validate the structure of the indexes associated with the table or cluster. If you use this clause when validating a
table, Oracle also validates the table's indexes. If you use this clause when validating a cluster, Oracle also validates all the clustered tables' indexes,
including the cluster index.
If you use this clause to validate an enabled (but previously disabled) function-based index, validation errors may result. In this case, you must rebuild the
index.

RBO X CBO

Hi everybody.
I would like to understand where what we are missing here.
We have several installations running 10g, and it's default value for OPTIMIZER_MODE is ALL_ROWS. Well, if there are no statistcs for the application tables, the RDBMS uses by default RULE BASED OPTIMIZER. Ok.
After the statistics are generated (oracle job, automatic), the RDBMS turns to use COST BASED OPTIMIZER. I can understand that.
The problem is: why do several queries run much slower when using CBO? When we analyze the execution plan, we see the wrong indexes being used.
The solution I have for now is set OPTIMIZER_MODE=RULE. Then everything runs smoothly again.
Why does this happen? Shouldn't CBO, after the statistics are generated, find out the best execution plan possible? I really can't use CBO on our sites, because performance is so much worse...
Thanks in advance.
Carlos Inglez

Hi Carlos,
The solution I have for now is set OPTIMIZER_MODE=RULE. Then everything runs smoothly again.It's almost always an issue with CBO parms or CBO statistics.
There are several issues in 10g CBO, and here are my notes:
http://www.dba-oracle.com/t_slow_performance_after_upgrade.htm
Oracle has improved the cost-based Oracle optimizer in 9.0.5 and again in 10g, so you need to take a close look at your environmental parameter settings (init.ora parms) and your optimizer statistics.
- Check optimizer parameters - Ensure that you are using the proper optimizer_mode (default is all_rows) and check optimal settings for optimizer_index_cost_adj (lower from the default of 100) and optimizer_index_caching (set to a higher value than the default).
- Re-set optimizer costing - Consider unsetting your CPU-based optimizer costing (the 10g default, a change from 9i). CPU costing is best of you see CPU in your top-5 timed events in your STATSPACK/AWR report, and the 10g default of optimizercost_model=cpu will try to minimize CPU by invoking more full scans, especially in tablespaces with large blocksizes. To return to your 9i CBO I/O-based costing, set the hidden parameter "_optimizer_cost_model"=io
- Verify deprecated parameters - you need to set optimizer_features_enable = 10.2.0.2 and optimizer_mode = FIRST_ROWS_n (or ALL_ROWS for a warehouse, but remove the 9i CHOOSE default).
- Verify quality of CBO statistics - Oracle 10g does automatic statistics collection and your original customized dbms_stats job (with your customized parameters) will be overlaid. You may also see a statistics deficiency (i.e. not enough histograms) causing performance issues. Re-analyze object statistics using dbms_stats and make sure that you collect system statistics.
Hope this helps. . .

Oracle Performance tunning genral question

Hi,
Below is the list of Areas of Oracle db for which tunning activities are done. You are invited to comment to it weather this is complete list or need some addition or deletion. As I'm learning PT for Oracle now a days, therefore I want to expand my knowledge by sharing what I'm learning and what I need to learn.
So comment with Open hearts on it. Espically from experts and Gurus.
Here is the List
1-Planning for Performance, include Storage consideration( Weather it is SAN, NAS, DAS), Network planning and host OS planning with proper configuration for running Oracle.
2-Database desining (Not under-Normalized and not Over-Normalized with proper usage of Indexes, views and Stored Procedures)
3- Instance tunning (Memory structure + B.g Processes)
4- Session tunning.
5- Segment Space tunning.
6- SQL tunning.
This is what uptill what I've learned. If it needs addition kindly tell me what are these. Please also provide me links(good and precise one) for PT tutorials on web.Also note that I'm discussing this w.r.t Single instance non-rac db.
Looking for Good sugessions

Explain plan looks ok but query still slow

hi,
i have a query that from the explain plan it looks ok( at least to me) but the query is taking very long time to return results
how can i further improve its performance ?

      INDEX RANGE SCAN     Cardinality=11     Cost=1     Optimizer=ANALYZED     Object name=FDC_ALARM_IDX2tks & rdgs

Hi,
I agreed with Nicolas. But I have few suggestion for.
First you check the indexes used is fine or not.
-FDC_SSALARMACTIVE
-FDC_SSALARM_IDX
Because I am confuse here
""TABLE ACCESS BY INDEX ROWID     Cardinality=417     Cost=7415     Optimizer=ANALYZED     Object name=FDC_SSALARMACTIVE"
IF the table is accessed by index rowid then why both the Cost & Cardinality is that much high.
Thanx.. Ratan

TIP 03: Transportable Tablespaces in 10g by Joel Pèrez

Hi OTN Readers!
Everyday I get connection on Internet and one of the first issues that
I do is to open the OTN main page to look for any new article or any
new news about the Oracle Technology. After I open the main page of
OTN Forums and I check what answers I can write to help some people
to work with the Oracle Technology and I decided to begin to write some
threads to help DBAs and Developers to learn the new features of 10g.
I hope you can take advantage of them which will be published here in
this forum. For any comment you can write to me directly to : [email protected]
Please do not replay this thread, if you have any question related to
this I recommend you to open a new post. Thanks!
The tip of this thread is: Transportable Tablespaces
