Difference between 10g and 11g OEM

Hi,
I would like to know what is the difference between 10g and 11g Grid control. Unfortunately I have worked only on 11g Grid Control. So do not not what exactly are the differences like from GUI features,installation steps.
Thank you....

Hi,
From 11g grid Weblogic also introduced. You can refer this below note for understanding even architecture.

Is there any difference between 10g and 11g M Views?

Hi,
I need to give a demo on and working examples of materialized views. The requirement is this: Master tables are in a 10g R2 DB, MV is in a 11g.
I just create a DB Link in 11g to point to the 10g DB and then create the MV in 11g.
Will there be any problems creating a 11g MV using 10 Master tables?
My question is are there any significant differences between 10g and 11g MViews??
Thanks & Regards,
Channa.

You have to be careful about your versions. 10g could be 10.1 or 10.2 11g could be 11.1 or 11.2
I wouldn't have an 11.2 database with a database link against a 10.1 database.
In fact, even with 10.2, I would try to ensure that I have a "high patchset" (10.2.0.4 or 10.2.0.5) although, in theory, 10.2.0.1 should also work.

Physical Joins Difference Between 10G and 11G?

Hi All, I have started using OBIEE 11G. Anybody please let me know is there any difference in applying physical joins in OBIEE 10G and 11G.
I heard that we need to join Fact and Dim tables in reverse way in 11G.
Thanks in Advance.

Differences between 10g and 11g

Greetings to all,
I am a student who was directed to this site to download Oracle 11g express edition release 2 and Oracle SQL developer 3.1 for class. However, I found only the 10g express edition to be compatible with my OS. I was told I could probably use this but was warned that my certification test would be in 11g. May I get some experienced opinions on if this would be a wise choice? What are the primary differences between the two?
Thanks in advance.

May I get some experienced opinions on if this would be a wise choice?It depends on the scope of the certification test. For basic SQL certification, either is probably OK. For a DBA certification that covers features only available in Standard or Enterprise Edition, or features added in 11g, you need the appropriate version.
What are the primary differences between the two? 10g XE vs 11g XE differences:

ROW_NUMBER differences between 10g and 11g

Hi and apologies if this has been previously answered, I searched but could not find a relevant answer.
I have a simple table: X
Address Entity Source
13534780 547045234 A
5903573 547045234 A
9805116 582004049 A
9808958 582004049 A
6429371 583032305 A
6669148 583032305 A
When I run the following SQL:
select Address,Entity,row_number() over (partition by Entity order by Source) as RN from X;
Oracle 10g yields:
Address Entity RN
5903573 547045234 1
13534780 547045234 2
9805116 582004049 1
9808958 582004049 2
6429371 583032305 1
6669148 583032305 2
whereas 11g yields:
Address Entity RN
13534780 547045234 1
5903573 547045234 2
9808958 582004049 1
9805116 582004049 2
6669148 583032305 1
6429371 583032305 2
If I repeat these runs , they are always consistent within each version of the database which is what I would expect.
Is this due solely to the order the table rows have been loaded and how can I within the query ensure parity between the two versions.
Thanks.

Is this due solely to the order the table rows have been loaded No.
Rows are inserted in no particular order.
Use an ORDER BY if you want/need ordered data.
Something like
select address
,      entity
,      row_number() over (partition by entity order by source) as rn
from   x
order by whatever_column_you_need;"Do not ever count on the order of rows from a query unless you have an ORDER BY statement on your query!"

NVL in view: discrepancy between 10G and 11G

Hi,
I've discovered some discrepancy between 10G and 11G in a way how view deals with NVL-based column in a where clause.
Here are two examples:
*10G:*
Connected to:
Oracle Database 10g Release 10.2.0.4.0 - Production
SQL> create table test_nvl (null_column number);
Table created.
SQL> insert into test_nvl values (null);
1 row created.
SQL> commit;
Commit complete.
SQL> create view view_nvl as select nvl(null_column,0) null_column from test_nvl;
View created.
SQL> select * from view_nvl where null_column is not null and null_column = 0;
NULL_COLUMN
0
*11G*
Connected to:
Oracle Database 11g Release 11.2.0.1.0 - 64bit Production
SQL> create table test_nvl (null_column number);
Table created.
SQL> insert into test_nvl values (null);
1 row created.
SQL> commit;
Commit complete.
SQL> create view view_nvl as select nvl(null_column,0) null_column from test_nvl;
View created.
SQL> select * from view_nvl where null_column is not null and null_column = 0;
no rows selected
Does anyone know why it behaves differently?
I couldn't find any documentation regarding this.
Or I'm just missing something here.
Thanks

Data mismatch between 10g and 11g.

Hi
We recently upgraded OBIEE to 11.1.1.6.0 from 10.1.3.4.0. While testing we found data mismatch between 10g and 11g in-case of few reports which are including a front end calculated column with division included in it, say for example ("- Paycheck"."Earnings" / COUNT(DISTINCT "- Pay"."Check Date")) / 25.
The data is matching for the below scenarios.
1) When the column is removed from both 10g and 11g.
2) When the aggregation rule is set to either "Sum or Count" in both 10g and 11g.
It would be very helpful and greatly appreciated if any workaround/pointers to solve this issue is provided.
Thanks

OLAP differences between 10g and 9i

Hi, is there any documentation on new / changed features in OLAP 10g vs. OLAP 9i. I'm currently installing all of the 10g products (now that the new BI Beans for 10g is out), but couldn't find a "whats new" on the OLAP side.
Thanks!
Scott

There use to be an OLAP 10g Data Sheet up on OTN that provided the new features. I'll ping them and ask them to re-post it and the other missing OLAP 10g documentation and white papers.
I pasted it below:
Partitioned Variables
The multidimensional engine provides direct support for partitioned variables. This support for partitioning presents many opportunities for both enhancing manageability and supporting large multidimensional data sets.
Three partitioning methods are supported:
â¢ Range partitioning allows data to be partitioned based on a range of dimension members. For example, one partition might contain time dimension members that are less than '13', another that are less than '25', and so on.
â¢ List partitioning allows data to be partitioned based on a list of specific dimension members. For example, a partition might contain dimension members <'JAN02','FEB02','MAR02'> and other partition might contain members <'JAN03','FEB03','MAR03'>.
â¢ CONCAT partitioning partitions data according to the dimension members that belong to a CONCAT dimension.
With each partitioning method, the multidimensional engine creates separate variables to store data. To the application, it appears that all data is stored in a single variable.
Scalability is enhanced in a number of different ways:
â¢ Data can be partitioned across time, thus providing the ability to store more historical data in the analytic workspace without affecting performance or manageability.
â¢ Calculations can be easily limited to a subset of dimension members, or they can be parallelized. For example, aggregations, allocations and other calculations can be performed on time periods within a particular partition.
â¢ Data loading can be parallelized.
â¢ When partitioned by the logical model, for example, by level of summarization, the definition of the variable can be adjusted to account for changes in sparsity between detail data and summary data.
â¢ Disaster recovery tasks can be performed on subsets of data and can be parallelized.
â¢ Partitioned variables can be partitioned across different data files and disks to minimize I/O bottlenecks.
Enhanced Storage Model
The storage model is enhanced to support the placement of objects in the analytic workspaces into specific rows of the AW$ table. Objects can be further partitioned by segment size to allow for large objects. The AW$ table can then be partitioned across multiple data files.
The obvious benefit of the enhanced storage model is that database administrators have complete control over how data is distributed across data files and can therefore optimize I/O for data and data access patterns.
Multi-Writer Mode
The multidimensional engine supports a multi-writer attachment mode, which allows an analytic workspace to be modified simultaneously by several sessions. In multi-writer mode, users can simultaneously modify the same analytic workspace in a controlled manner by specifying the attachment mode (read-only or read-write) for individual variables, relations, valuesets and dimensions.
The MULTI attach mode provides the opportunity to parallelize any number of activities in the analytic workspace. Some examples follow:
â¢ Using separate simultaneous sessions to load data into different variables can parallelize data loading tasks. For example, different sessions could be used to load data into SALES and COST variables. When combined with partitioned variables, different sessions could load into each partition in parallel.
â¢ Separate sessions can be used to aggregate separate variables or partitions of a variable.
â¢ Separate sessions can be used to solve models, allocations and virtually any other calculation within the analytic workspace as long as the calculation is directed to different variables or partitions of a variable.
Parallel Update
The OLAP DML UPDATE command runs automatically in parallel on partitioned variables, thus optimizing performance of this command on servers with multiple processors. Significant improvements will be seen in cases where large volumes of data are updated (such as a data load or aggregation) and partitioned variables are used.
Aggregation from Formulas
Oracle OLAP 10g allows formulas to be used as a source of data to the AGGREGATE command. This eliminates the need to calculate and store data at the detail level, yet still retains the ability to aggregate to summary levels. The benefit is that the multidimensional engine presents large volumes of derived information from relatively little stored data.
Optimizations to Composite Dimension Indexing
New 64-bit B-Tree+ indexes and optimizations to the process of synchronizing composite dimensions to base dimensions support excellent query response times with very large composite dimensions (for example, composite dimensions in excess of 1 billion members).
Certified with Real Application Clusters and Grid Computing Real Application Clusters and Oracle Grid Computing provide a database platform of virtually limitless computing capacity and scalability. The multidimensional engine and data types of the OLAP option, being part of the Oracle Database, have been tested with Real Application Clusters and Oracle Grid Computing. This provides Oracle OLAP the capability to support very large user communities and data sets.
Wider Relational Filters to Multidimensional Data Types
The OLAP 10g optimizes a wider range of SQL predicates when selecting from multidimensional data types. This is accomplished by applying SQL filters before the data is converted to a row set using OLAP_TABLE. As a result, the risk of pushing large volumes of data through OLAP_TABLE is minimized and applications need not be as concerned with optimizing SQL for selecting from OLAP_TABLE. The net result is that a wider variety of SQL applications can be used with the OLAP option without special considerations.
Support of SQL Model Clause
Oracle Database 10g introduces OLAP-like calculations that are expressed with a SQL MODEL clause, which is similar to what the OLAP community commonly refers to as custom dimension members. A custom dimension member is a virtual member whose value is calculated at runtime.
The SQL MODEL clause provides an additional method for defining certain types of calculations against multidimensional data types, and the SQL interface to multidimensional data types has been optimized for SQL models. Optimization occurs by having the multidimensional engine completely bypass OLAP_TABLE as data is being returned.
As a result, the processing of SQL with the MODEL clause is highly efficient against multidimensional data types. In many cases, performance of MODEL with multidimensional data types exceeds that of the same SQL against relational tables. This provides SQL based applications with both new analytic features and performance advantages.
Query Rewrite to Views over Multidimensional Data Types
In Oracle Database 10g a new feature, query equivalence, allows query rewrite to be used with views. With query equivalence, the DBA indicates to the database what SQL could have been used to create the view even if the view was created in some other way. For example, if the application likes to emit SQL with SUM â¦ GROUP BY but the view was created with entirely different SQL, the DBA could indicate that the view is equivalent to SUM â¦ GROUP BY.
This feature of the database is extremely useful with the OLAP option since SQL access is always through views. This provides the DBA and application with benefits similar to those of materialized views â simplified maintenance and improved query performance.
Automatic Runtime Generation of Abstract Data Types
Abstract data types are used by object technology of the Oracle Database to define the relational columns for data that is returned from a non-relational data source. In the case of the OLAP option, abstract data types describe data being selected from analytic workspaces in terms of relational columns.
Previously it was a requirement that abstract data types be created as part of the administrative process of enabling analytic workspaces for query by SQL. To provide applications and database administrators with additional flexibility in the administration of SQL access to analytic workspaces, Oracle OLAP 10g supports automatic runtime generation of abstract data types as part of the query process.
With the addition of this new feature, it is now possible to query analytic workspaces without requiring the DBA to predefine either abstract data types or views.

For the code below, in Oracle 10g, it says the node is empty, in 11g, it's not empty. There is a newline character in side the tag .
If there is a space inside, the result is the same for both version.
Once nothing inside, both two version will not have the output.
Why does this happen ?
DECLARE
v_doc dbms_xmldom.DOMDocument;
v_elem dbms_xmldom.DOMElement;
v_nelem dbms_xmldom.DOMNode;
BEGIN
-- create the DOMDocument
v_doc := dbms_xmldom.newDOMDocument(xmlType('<XMLDATA>
</XMLDATA>'));
v_nelem := DBMS_XMLDOM.MAKENODE(v_doc);
v_nelem := DBMS_XSLPROCESSOR.SELECTSINGLENODE(v_nelem,'XMLDATA/text()');
IF NOT(dbms_xmldom.ISNULL(v_nelem)) THEN
DBMS_OUTPUT.PUT_LINE('The node is not empty');
END IF;
END;

Differences between 10g and 11i

Hello Everyone,
I am new to Oracle development.
If I were learning Oracle 10g Standard Edition
and got comfortable in it and had some exposure
to it. How big of a jump would it be for me to
pick up Oracle 11i?
Thanks,
Nick Ueda

10g is a version of the Oracle database. 11i is a version of the Oracle applications suite. The two are completely independent (though Oracle's applications suite does use the Oracle database on the back end).
