Oracle DB 10g and BI Discoverer for OLAP - Dimension Attributes

Hi,
We are using Oracle Database 10g release 1 with partitioning, data mining and OLAP options and Analytic Workspace Manager 10.2.0.1.0A to create the multidimensional objects. For the user dimensions created using AWM we have custom attributes like HireDate, StartDate, Sales Personnel Role etc., For reporting purposes we are using Discoverer for OLAP. In this Discoverer version, I don't see an explicit provision to drag these attributes onto the worksheet. We are only able to filter based on these attributes and capture the measures...
Can someone throw light on this? Also, if there is a possibility to drag these attributes onto the worksheet can that be expounded?
Thanks in advance!

Again this depends on what you are trying to achieve. If you define an attribute against a dimension it takes very little space as it is not directly connected to a cube and so no data is stored against that attribute.
If, however, you have a 4D revenue cube (product, geography, channel, time) with products attributes COLOR and PACK SIZE and you want to view revenue additionally borken-out by COLOR and PACK SIZE as well as the other four dimensions then your schema will require additional storage space. However, 10g compressed cubes and sparsity options do help to manage the explosion of data points as the number of dimensions increases. This should allow you to easily add attributes as dimensions into your cube.
One thing to remember is that most users start to struggle when confronted with more than 9 dimensions. So although Oracle OLAP can create extremely large dimensional models, users prefer their cubes to have 9 or fewer dimensions.
Hope this helps,
Keith

Difference in select for update of - in Oracle Database 10g and 11g

Hi, I found out that Oracle Database 10g and 11g treat the following PL/SQL block differently (I am using scott schema for convenience):
DECLARE
  v_ename bonus.ename%TYPE;
BEGIN
  SELECT b.ename
    INTO v_ename
    FROM bonus b
    JOIN emp e ON b.ename = e.ename
    JOIN dept d ON d.deptno = e.deptno
   WHERE b.ename = 'Scott'
     FOR UPDATE OF b.ename;
END;
/While in 10g (10.2) this code ends successfully (well NO_DATA_FOUND exception is raised but that is expected), in 11g (11.2) it raises exception "column ambiguously defined". And that is definitely not expected. It seems like it does not take into account table alias because I found out that when I change the column in FOR UPDATE OF e.empno (also does not work) to e.mgr (which is unique) it starts working. So is this some error in 11g? Any thoughts?

It seems that my question was answered here - http://stackoverflow.com/questions/2736426/difference-in-select-for-update-of-in-oracle-database-10g-and-11g

The behaviour seems like it really is a bug and can be avoided using non-ANSI syntax. (It makes me wonder why Oracle maintains two query languages while dumb me thinks that this is just a preprocessor matter and query engine could be the same).

Where to locate HTTP Server for use with Oracle Express 10g and Apex?

Hello,
Im a newbie and I downloaded oracle express 10g and Apex 3.2.1. The Apex install is referencing "choosing a HTTP Server" specifically "Oracle HTTP Server and mod_plsql and the embedded PL/SQL Gateway". My question is do the HTTP server or PL SQL embedded Gateway come with the 10g install or do I need to download them seperately? If so where can I locate them?
Thank you!

user12027813 wrote:
If using Oracle XE, then which APEX install scenario would I used if I downloaded both the XE and apex from the OTN?Oracle XE includes APEX 2.1 and uses the PL/SQL Gateway for HTTP service work. No separate HTTP Server is required.
If, after you install XE, you want to upgrade to APEX 3.x, you would select the PL/SQL Gateway for the upgrade.
If the PL/SQL Gateway (EPG) does not provide the full set of services you need, you could put a regular Apache in front and redirect to APEX for those specific issues.
If that is to complicated, then you could license Oracle Application Server Standard Edition 1 (for a fee) to get an Oracle HTTP Server and it's mod_plsql to replace the internal EPG.

Help me for Configuration on Oracle AS 10g and WebSphere MQ

If there someone can share there experience on configuration on Oracle AS 10g and WebSphere MQ. Is there some quite easy ways or tools to do this?
Welcome any advise!

Hi,
The only thing I know of is the documentation to configure the resource provider and I think there is an example on Technet:
"Declaring an IBM WebSphere MQ Resource Provider Reference"
[http://download.oracle.com/docs/cd/B32110_01/web.1013/b28958/jms.htm#i1086751|http://download.oracle.com/docs/cd/B32110_01/web.1013/b28958/jms.htm#i1086751]
and
[http://www.oracle.com/technology/tech/java/oc4j/1013/how_to/index.html|http://www.oracle.com/technology/tech/java/oc4j/1013/how_to/index.html]
I think the important thing is to note step 3 of the documentation,
Add to J2EE_HOME/applib any JAR files required by a Websphere MQ JMS client
as described in the IBM documentation.
I assume this comes from an MQ library that should be installed in OC4J.
If you use applib you must restart OC4J before it will be seen also.
I hope this can guide you in the right path.
Sincerely,
Steff

Hi all,
I would like to know what the differences between Oracle and other NoSQL database are.
When and why should we use Oracle?I suggest that you start here:
http://www.oracle.com/technetwork/database/nosqldb/overview/index.html
Is Oracle NoSQL database link with Big Data Appliance?Yes, Oracle NoSQL Database will be a component of the Big Data Appliance.
Can we use map-reduce on a single personal computer? How should we install Oracle NoSQL database to use map reduce on a single personal computer?Yes, I believe you can run M/R on a single computer. Consult the various pieces of documentation available on the web. You may run Oracle NoSQL Database on the same computer that you are running M/R on, but it is likely that they will compete for CPU and IO resources and therefore performance may suffer.
Do we also have eventual consistency with Oracle NoSQL database? Yes.
Can we lose data if master node fails?If you run Oracle NoSQL Database with the default (recommended) durability settings, then if the master fails, a new one will be elected and data is not lost.
Are transactions ACID with Oracle NoSQL database? How can we prove it?Yes, each operation is executed in an ACID transaction. The API has the concept of "multi" operations which allow the caller to perform multiple operations on sets of records with the same major key, but different minor keys. Those operations are also performed within a transaction.

Running Oracle database 10g and 11g on same 5 RAC nodes

Hello Gurus,
Could any body throw light if I can install and sucessfully run Oracle database 10g and 11g on the same Oracle RAC installation setup.My setup is below
Number of nodes-5
OS- windows 2003 or RHEL5
storage- DELL EMC SAN
Clusterware- oracle version11g
File system-Automatic storage management(ASM)
After I successfully setup clusterware,ASM on the nodes,I would want to install 11g database on all 5 nodes .
Then Install 10g database on only 3 of the nodes using the same clusterware.
What are your views on the same.
Also FYI... as per metalink node 220970.1(RAC: Frequently Asked Questions) one can do such a setup.
what iam looking for is practical experience if anyone has implemented this in production system,if yes any issues faced and how tough it is to support.
Thanks,
Imtiyaz

You could run an 11g database and 10g database on the same cluster as long as you use Clusterware 11g.
The administration aspect will drastically change according to the platform you run on. As of now, it appears you don't know whether it will be Linux or Windows.
It would be practical to support the same database release.

Oracle 11G,10g and DB2 replication?

Oracle 11G,10g and DB2 replication?
=======================================
We are using Oracle 11gR2. We have a table in Oracle filled with partial data (over 200K+, it may grow to 1M). The rest need to be obtained from DB2. It is not from one DB2 table.
The DB2 is configured to run Oracle 10g within it. We have given http interface, where we need to supply(Push) the partial data using HTTP_UTIL package for each row, then DB2/Oracle 10g return the result as XML.
It is a network heavy, slow and not reliable.
Are we able to replicate tables between Oracle 11g and DB2/oracle 10g?
We like to leverage the features on 11gR2 effectively.
I find some interesting folks in this forum.
Did anyone face such situation?
I like to know the best approach with good performance options.
Any idea?
Thanks in helping.

Compatibility with Oracle RAC 10g and E-business 11i ?

Hi netpros,
I am currently helping the sales guys with a tender. The customer requires the solution to be compatible for delivering Oracle RAC 10g and e-business 11i. we are proposing a combination of Cat6509E for the core with Infiniband server switches. Are these devices OK for use with Oracle. I have not much experience with Data centers and so any help is much appreciated.

Hi,
It just so happens Cisco have a paper on exactly this subject (Oracle and e-business 11i) here:
http://www.cisco.com/application/pdf/en/us/guest/netsol/ns50/c649/ccmigration_09186a00807688ce.pdf
The design is somewhat OTT as it includes everything which Cisco thinks may be even vaguely useful, including ACE and FWSM modules. However, it's very useful as a comparison document and does include some good design tips, and the references at the end are also worth following up.
I wouldn't want to get into the whole Infiniband vs Fiber Channel argument (the doc uses MDS switches) but both work just fine in the DC environment.
HTH
Andrew.

Muhammad AliOkay I've haven't done 1z0-045 ... but I at one point I was considering 1z0-050 so I'm willing to share my views on an upgrade exam and exams in general.
Remember Oracle are trying to ensure that a DBA who was tested at 8i DBA OCP has nw
It depends on your definition of read the topics. If you mean literally just read the topics then that will result in a failure. If you mean study research practice and fully understand the topics that should lead to a pass.
Bear in mind that Oracle would expect a competent 8i DBA attending the 5 day training course Oracle Database 10g: New Features for Oracle8i DBAs [http://education.oracle.com/web_prod-plq-dad/plsql/show_desc.redirect?dc=D17389GC10&p_org_id=&lang=&source_call=] to be able pass the exam with perhaps 2 to 4 weeks further study, revision and practice.
Interestingly this particular exam has a relatively high pass mark (73%) ... one implication of that is that it is prudent to be comfortable with all topics.
Generally an upgrade exam will cover topics beyond that of the straight OCA/OCP exams. The questions will obviously be at OCP level.
It is possilble the Sybex book Oracle 10g New Features for Administrators Study Guide (Certification Study Guide) ISBN-13: 978-0782143553 which although for 1z0-040 may have some relevance for some of your topics. If you choose to purchase it that is your choice. (It seems to have good amazon reviews ... though all of these books can contain errors, it may or may not be updated for 10gR2, and some Sybex Oracle books are sometimes OTT in some areas IMHO, but that wouldn't stop me using one).

Oracle Database 10g and Oracle Client 9i together

Hi, I've been lost some nights in this problem, in my job I will need migrate my Oracle Database 10g for a new computer, on the other hand, there is a software in this computer wrote in Visual Basic and this running only Oracle 9i Client.
Is it possible configure my new server for run Oracle Database 10g and Oracle 9i Client together?
Thanks!
Emerson

You can certainly use an Oracle 9i client to connect to an Oracle 10g database. Technically, you may have to apply the 9.2.0.4 patchset to the Oracle client to be completely supported, but that may not be strictly necessary.
You can also have both a 10g database and a 9i client installed on the same machine in different Oracle Homes. You may have some issues on Windows, however, if you are using software that is not multi-home compliant (i.e. the Microsoft ODBC driver for Oracle) or if you call Oracle command-line utilities (exp, imp, etc) without explicitly setting the PATH first.

Doubt with Windows and Oracle Forms 10G and 11g

Hi
I have some doubts in installing Oracle Client on Windows.
a)Can we install Oracle Forms 10g and Reports 10g client on Windows 7?
b)Can we install Oracle Forms 11g and Reports 11g client on Windows XP?
c)If we have an Oracle Forms 11g and Reports 11g, can it connect to a 10g Server?
d)If we have an Oracle Forms 10g and Reports 10g Client, can it connect to an 11g Server?
Please, Can any one help me in this????

a)yes it can be installed on win7, may have some issues on 64bit systems but they're solvable
b)11g had some problems with windows 2000, but didn't see mention of any problems on XP
c)if you mean a database server then yes - i managed to connect 11g to an 8i database, so v10 should not be a problem. If you mean a forms/reports server..well newer forms/reports builder might not want to run old forms/reports and vice versa, but I don't see the point of operating on the same files from different versions. You can still load old form/report source files with a newer builder and recompile them to run on the new server.
d) the "client" is effectively your web browser with a java plugin, unless I misunderstood your question. What version was a form/report compiled with should not be an issue.

Slow Problems with Oracle Forms 10g and Oracle Database 11g

Hi, I wonder if there is a compatibility problem between Version 10.1.2.0.2 32 Oracle Forms and Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production. This is because my application runs correctly on a version of Oracle Database 10g, and when we migrated the database to an Oracle Database 11g, slowness problems came out.
Thanks.

We have the same issue happening with our custom forms and with some of the standard forms in EBSO. So far we have found that the form invoking a view causes ridiculous slowness in opening the form (40 mins). Using a table access has shortened the open time significantly. At this time Oracle DBAs at OOD have no clear idea why it is happening.
we are on 11.1 database with 11.5 EBSO
