In Next few days , I am going to start writing on Oracle new database version 11G . Following topics will be covered and most of the topics will be related to DBA's.
Some of topics coverered will be :
Oracle 11G : Installation and Upgrade Enhancements
I was with a client who had asked me to install oracle on linux 64 bit . It was quite a small task and as a Oracle Consultant it is very easy but the problem I had that ClientDBA had copied the software from CD to server and left and none knew whether the software was 32 bit or 64 bit :(
I could have made my life easy by downloading the correct software from OTN and transfer it to server but again the problem was with the network as it was remote installation .
How to find whether the software is 32 bit or 64bit :
Go to Disk3/stage/Components/oracle.options.odm/9.2.0.4.0/1/DataFiles/ in the installation kit.
% cd Disk3/stage/Components/oracle.options.odm/9.2.0.4.0/1/datafiles
Copy lib.1.1.jar file in a new directory, outside the installation kit
% cp lib.1.1.jar $TMP
Unzip the file
% unzip lib.1.1.jar
execute "file" command for dmndm.o
% file dmndm.o
This is a file specific to DataMining. If this file is 32 bit, then your software is 32bit. If the file is 64bit, then the software is 64bit
It a very common to load file (data) from one character set to another character set.
Here I will give u an example:
We have created a csv file from a database which has got following NLS properties:
NLS_LANG=American_America.WE8ISO8859P1
Now we have to load the file in EBS using concurrent manager and the NLS details of the EBS are as follows
NLS_LANG=American_America.UTF8
If the source file has got some special characters (Western European characters), you will find that complete file is not loaded in EBS as the file generated is not in UTF8 character set.
Errors u may get are
Record 144: Rejected - Error on table "GL"."GL_INTERFACE", column REFERENCE10. Multibyte character error. Record 145: Rejected - Error on table "GL"."GL_INTERFACE", column REFERENCE10. Multibyte character error.
Table "GL"."GL_INTERFACE": 11968 Rows successfully loaded. 2 Rows not loaded due to data errors. 0 Rows not loaded because all WHEN clauses were failed. 0 Rows not loaded because all fields were null.
To resolve this issue, we have to do the following:
After the file is created and transferred to EBS server, it has to be converted to UTF8 character set before loading in EBS.
Recently we upgraded our EBS from 11.5.9 to 11.5.10.2 and found that whenever user clicks on Discoverer plus from the application, it always point to discoverer viewer which was not correct.
Reason for this issue is:
There is a profile option called ICX: Discoverer use Viewer which is set to YES by default. Hence Discoverer Viewer is always started even if discoverer plus is requested.
Hence we need to change the value of ICX: Discoverer use Viewer profile option to NO and bounce Apache for users to discover plus from EBS Application
Oracle Education has recently started new concept known "Oracle Expert" in certification which I think is very good as this will help us going for specialization within Oracle.
There are many streams which DBA's or Oracle Apps DBA can go for :
Oracle Database 10g: Managing Oracle on Linux Certified Expert
Oracle Database 10g: Real Applications Clusters Administrator Certified Expert
Oracle 11i Workflow Certified Expert
Oracle 11i System Administrator Certified Expert
The first two will be released soon in Beta version but the later ones ( For Oracle Apps DBA) have been released in Production.
This is one of the most usual tasks given to Apps DBA and from my past exp., DBA's spend more than 70% of time in Cloning.
Cloning Oracle Apps 11i is done through a tool given by Oracle known as RAPID CLONE and it is very easy to use but it does not do all the bits....
When u clone the env, there is a ref of the source env in the database in FND_NODES tables , thus after clone if u visit the OAM page , u will see both source nodes and target nodes . Also u will be some concurrent managers which have got ref to source nodes.
If u want to get rid of the source nodes , Do the following :Follow the Rapid clone document (Metalink note : 230672.1)
Prepare the Source System ( Pre Clone Steps )
Copy the Source System to the Target System
Configure the Target System o Configure the target system database server o After the database is created ,connect as apps and execute the following EXEC FND_CONC_CLONE.SETUP_CLEAN; Commit; o Above cmd will clean the FND_NODES table and does something more than that i.e.
c lear the concurrent manager tables etc. o Run the autoconfig.sh again on the database tier
And there after follow the doc Metalink note: 230672.1
Good news from Oracle for Oracle Apps DBA regrading certification .
Now it is easy to get certification for Oracle Apps DBA if u have 10G OCP or 9i OCP .
After careful review from the beta exams and DBA/customer feedback , the exams 1Z1-231 Implement Oracle Workflow 11i and 1Z1-232 Oracle 11i System Administration have been reapportioned so that the resulting credentials better fit their corresponding job roles.
Now if u have 9i or 10G OCP , u have to appear for one Apps exams to get OCP for Oracle 11i Applications Database Administrator Certified Professional ..
It is a very common question to find out the version of the Oracle Developer installed with Oracle Apps .What version , how to find out the version number and how to upgrade it.
This is required if u are planning to upgrade the oracle application database from 9i to 10G. One step is to upgrade the developer version
To find out the developer version ...Set the Apps env and use the following command :
Run $ORACLE_HOME/bin/f60gen help=y to display various component versions
My mentor and my Guru Sandeep Pandya for giving me directions in learning Oracle Application and gave full support during my learning curve as Oracle DBA and Oracle Apps DBA. While working with him , I learnt not only Oracle but other softskills like ITIL concepts , presentation skills.
My wife Anshul for her support and patience, inspite lot of personal time I spent in Office working late...
