... this is mandatory to achieve your OCP credential because without attending at least one module's training from OU ... IF I may, this is really an unfortunate requirement:
1) I passed my OCA11g. Given the economic situations, my company is "dragging" its legs in sending me to the required training from OU because of the costs it involves.
2) Plus, OU hardly ever comes to my state (probably due to low demand). So, if my company were to send me to the training, it'll have to be out of state, which means more expenses. Which unfortunately also means lower chances of me ever making it to the training classes; and consequently, me ever getting my OCP certifications.
I haven't given up on Oracle or anything like that YET; because we're still using Oracle at my workplace. However, since we also use MSSQL (used for the 3rd party applications that doesn't connect to Oracle), I have moved on to prepare for my MSSQL 70-432 exams and will probably continue on with the MCDBA path.
Given the economic situations, it's damn hard for companies to cough up 3000 for the class and 1-2 k more for out of state travel to attend the class. I'm not at all happy with this requirement.There are two things that might help to cut costs, but they probably wont.
- (1) Remember online (LVC) courses will satisfy the requirement.
- (2) Some of the satisfying courses course are 3 day (though you probably shoudn't take most of these until you have passed your 1z0-053 or reached that standard) ... and these are cheaper.

( In any order .... and probably the reverse of that given below is appropriate: )
A: Pass the 1z0-058 exam
AND
B: ( Either have authorized (wrt certification) 11g RAC training certified
Or attain 11g DBA OCP status (e.g. by passing 1z0-050 )

1Z0-051 Oracle Certification - OCA

Hi. I am in a fix and so need your help.
I am planning to give 1Z0-051 Oracle Certification exam(Oracle Database 11g- SQL fundamentals). However, I will be unable to give my 1Z0-052 exam(Oracle Database 11g- Administration-I) at this time. So, if I give only 1Z0-051 exam, then will it carry some weightage in my resume? Also, if I pass the 1Z0-051 exam, then how should I put it in my resume? That I am a Oracle Certified individual?

(If you need proof of this copy the report from the test center ... you cannot really get from of this from Oracle. Certview will publish certifcations, not exam passes). If you take this online there is no proof it was you you actually took the exam).
However you are not Oracle certified and must not put that in your resume ... you may only put it in your resumé when you have proof from Oracle you have been awarded a Certification.
The weight of this exam pass, and indeed any exam pass or certification, can depend on the reader(s) of the resumé; and the nature of job you are applying for; and the strength of the other candidates for the job. Suppose an employer was looking for CV's for a DBA job. Assuming the HR/agencies let the CV's through they might get (in practice a higher number of DBA OCPs might be expected):
Person with a 1z0-051 pass and degree and no experience.
5 with 9i DBA OCP, most with MA degrees, with no experience
10g DBA OCA obtained 3 years ago with no experience.
Apparently experienced DBA with no formal qualifications and no degree.
Now the first and last candidates have a high probability of being what they say they are, but the first wuld be no good if an experienced DBA was needed. It would be necessary at interview to be careful to check the others had the experience level claimed due to certifications being obtained though cheating and fraud. Its also worth noting DBA OCA does not cover backups / restores in depth.
However if what was needed was someone to query database results as a result of some tests the first candidate might acutally be the most suitable .. assuming he has studied the 1z0-051 carefully. The 10g OCA might not have done SQL ... the experienced DBA might feel that was not a suitable job for him, and the 9i DBA OCPs may have rushed (or cheated) their way through 1z0-007 as quickly as possible and would not be interested / capablle of this work.
(Please note this article is biased against 9i DBA OCP ... at one point my understanding is there was a particularly high level of cheating/fraud against this certification and some poor training from some WDP institutions ... which is a pity for those achieving the certification through due work and good training).

Can I attend Oracle 10g DBA course & attempt DBA Certification for 11g

Hi,
I am already OCP-PLSQL and want to attempt OCP-DBA stream. I enquired at various oracle education centers and came to know that all are conducting courses for Oracle-10g.
So can I attend Oracle 10g DBA course (Mandatory Course) and attempt DBA Certification for 11g. (1ZO-052 and 1ZO-053)
Thanks,
Vikrant Patil

Vikrant PatilYou can do these thing, and Oracle will take your money for it, but you will receive neither 11g DBA OCP certication nor 10g DBA OCP Certification at the end of it. So it isnt what you would ant to do.
Oracle Unviersity would provide the 11g DBA training courses ... No problem.
however I suspect what you term oracle education centers are probaby institutes offering WDP Courses at 10g DBA (on the cheap). See http://workforce.oracle.com
If you do 10g training then that will only be valid for 10g DBA OCP Certification .. so you would need to take 1z0-042 and 1z0-043 (I guess you already have an SQL Exam pass). Then 1z0-050 can upgrade it to 11g DBA OCP.
(Note that it does not affect you, but the converse is typically true .... version X+1 training will often be acceptable for a version X certification.)

Oracle RAC 11g on Windows 2008 64 bit - blue screen error on both nodes

Hi Everyone,
I installed Oracle RAC 11g on Windows 2008 64 bit, The installation was successfull and crs_state -t shows all services in two nodes are online.
When executed a select query with 100 sessions( For performance evaluation using Transaction generator ) ,the machine got crashed and blue screen is appeared on two nodes. I restrated the machines and and starts the same evaluation ,bt the same bug is repeating.
Can anyone suggest a solution to solve this issue? Is our hardware is not sufficient ? Shall we need to perform any
specific settings in Oracle RAC setup for performance evaluations?
Is our settings for load balancing is not enough? ( We added "Load Balancing= On" on tnsnames.ora on client for load
balancing)
The following machine configuration is used for Oracle RAC setup
Intel Core 2 Duo 2.66 GHz,
Ram :4GB.
OS : windows 2008 Server 64 Bit
Oracle RAC 11g , Clusterware 11g R2 , ASM with 5 raw disk ( 1- votting disk ,1- ocr files and 3 disk files)

Weblogic certification 11g 1z0-102

Looking for a good book to prepare for this exam.
Right now I am reading Oracle Weblogic Server 11gR1 PS2: Administration Essentials by Michel Schildmeijer.

You can try with oracle weblogic server 11g administration handbook - Sam Alapati.I already bought this book and have completed first three chapters.I think this book is the best guide for Weblogic certification.Good Luck.

Oracle 10g RAC to 11g RAC Upgrade on Solaris

Hi,
We are planning to do a migration of a 4 Node Oracle 10g RAC on Solaris 9 to 11g with Solaris 10. We'd like know what would be the best path to take. We cannot afford any downtime!
Options: Are these feasible? Which option is best? Any documents links?
a) Do a rolling upgrade of Oracle from 10g to 11g. Then take down individual nodes and upgrade the Solaris OS from 9 to 10 and bring them up back into the cluster. Is there any known issues taking this path? Is a rolling upgrade like this possible?
b) Do an upgrade of the Solaris OS from 9 to 10 on each node and then bring them back up? Is this practical? Does Oracle allow different versions of OS running on different nodes?
c) Use Dataguard with 2 different RAC environments (2 nodes each). How would this work? Is it the only possible way? Any steps please?
Thanks

a) Do a rolling upgrade of Oracle from 10g to 11g. Then take down individual nodes and upgrade the Solaris OS from 9 to 10 and bring them up back into the cluster. Is there any known issues taking this path? Is a rolling upgrade like this possible?Hi,
first of all i would not change several components (OS, database version) at a time. My recommendation is to make small steps and start with the operating system first. Seconds recommendation is to test and test everything in your dev or test environment prior doing the upgrades in the productive environment. Trust me: You will face problems :-) So you better try it beforehand!
b) Do an upgrade of the Solaris OS from 9 to 10 on each node and then bring them back up? Is this practical? Does Oracle allow different versions of OS running on different nodes?As far i know you can run different operating system versions on different nodes if they are supported (Solaris 9 and 10 are).

Oracle RAC 11g query

Hi All,
I am new to Oracle RAC 11g, facing a issue, Request all to help.
1) What is the instance id means which we get from gv$session in Oracle RAC setup?
2) What is differnce between Session failure and node failure?
3) If session fail, then client should connect to node1(to which session previously connected) or node2?
Thanks

1) What is the instance id means which we get from gv$session in Oracle RAC setup?Instance ID is unique for each instance in clustered database.
2) What is differnce between Session failure and node failure?Session Failure - when the connection to an instance is lost, SESSION failover results only in the establishment of a new connection to another Oracle RAC node
Node Failure/Eviction - we can say hardware fails, the Cluster Manager reports the change in the cluster's membership to Global Resource Directory (GRD)
Resource directory which consists of both Global enqueue service & cache service
3) If session fail, then client should connect to node1(to which session previously connected) or node2?You have to configure in SERVICE.

Please reply soonYou know that the modifications you'have done on spfile are not active until you restart DB. So why don't you want to modify the spfile by "alter system ... scope=spfile" commands? I don't see the point to create pfile, modify it and recreate spfile...

Error during installation Oracle RAC 11G

Hi experts;
I'm installing Oracle RAC 11G, this installation will be in two virtual servers, OS Linux redhat.
I began the installation with these steps
Configure Security Updates
then ask for proxy server information (nothing was entered), continue
Installation Option (don't ask anything)
then System Class (Server class selected)
Grid Options
(Real Application Clusters database installation)
when hit ENTER I got this errror message - (INS - 35354) The system on which you are attempting to install Oracle RAC is not part of a valid cluster.
I was looking in some forums an I found one where indicates I should indentiify these files and change some info on them;
=============================================================================
cat /etc/oraInst.loc
The ouput of the above command lists the inventory_directory
Browse to the inventory.xml file in that directory. My oraInventory
cd /u01/app/oracle/oraInventory/ContentsXML/
cat inventory.xml
You can verify that the flag CRS=true isn’t set for the $GRID_HOME
==============================================================================
However, I couldn't find any of those files in my directories.
also, i was verifying the note [ID 1053393.1, but again, I couldn't find where to change the values for CRS.
Any idea what I'm doing wrong?
I will apreciate your help.

Hi,
RAC is a database in a cluster. One Database opened by one o more instances in one or more hosts.
Note: RAC is not a cluster, but a Database cluster.
To allow database be clustered, we need to install a software cluster.
We have some options, but Oracle developed your own software cluster actually named Grid Infrastructure for a cluster AKA Oracle Clusterware.
To install RAC you need first install and configure your cluster.
Before you start install Oracle cluster/RAC I recommend you start with concepts.
