• Oracle 10g on Oracle Enterprise Linux 6 using VMWare

  I am trying to install Oracle 10 g on a Linux server. The reason is that the system, which I am working 10g and want a test environment on my computer.
  I installed the latest version of Oracle Enterprise Linux 6 on VMWare Player.
  So far so good.
  Now I want to install 10g on the system and have read both Expert Oracle 10 g database Administration and the fast for 10g Release 2 Setup Guide (10.2) for Linux x 86
  I seems to be now stuck in the situation to get all loaded packages that are recommended. Some of the packages are not on the cd, so I'm starting to wonder if it is a valid version for installation.
  Because the version is releast Red Hat Enterprise Linux Server 6.0, I had that with
  # cat/etc/redhat-release
  
  So 10g is not supported on this version?
  If so do I download the previous version of Linux?
  If so what version and if you can direct me in the sense I would be really happy.

  Currently 6 Linux is not certified to any version of database Oracle.

  Operating system for 10 g 2 (which is what I assume you are using) is listed in the Release Notes - http://download.oracle.com/docs/cd/B19306_01/relnotes.102/b15659/toc.htm#CHDFHIEA

  Everything you did for RHEL5.2 will work perfectly in OEL5.2

  You raise a very good point: the unfortunate fact is that there is * nothing * to all to OEL a house "better" or "easier" for that plain old RHEL Oracle databases. There is no core set environment variable user parameters or pre configured, for example, it would be just for an Oracle straight out of the box installation: you must always you fix all exactly as if it were of RHEL.

  This is normal: OEL was and is intended to be binary compatible with RHEL and therefore no settings of Oracle or parameters that are not in RHEL can be included in the OEL.

  So yes, if it's complicated on RHEL, it is exactly as complicated as on OEL.

  (I'm biased though: If you use my script to doris, you will find that you can install Oracle on virtually any Linux distribution as easily as any other.) See http://dizwell.com/2008/05/01/doris-redux, and if you want to watch a video of how to do to use the script: http://dizwell.com/2008/09/29/proving-a-point/)

• I want to improve my skills in sql and plsql

  Hello friends,

  I finished the course SQL and PLSQL a few weeks back. Since then I've been hunting for a relevant work for SQL / PLSQL developer.

  However I really want to improve my writing of the subprogrammes, build effective SQL queries to become a skilled oracle developer.

  My current work is not linked to this use so all my free time to improve my knowledge in this area.

  I know the basics of SQL and PLSQL concepts and can write queries simple, subprogrammes, but to become employable, according to me, that I need to learn a lot more.

  Please suggest me some good sources be it no books / sites Web, etc. anything that would really help me become a good developer.

  I'm desperate to make a career out of Oracle SQL / PLSQL!

  Thanks in advance.

  Do what most of the experts do... start at the bottom.

  Find a job in a junior role (and yes it will be low wages initially) where the company may see your potential and enthusiasm to learn and will give training and let you learn on the job.  If you have the skills to do it, then you will learn quickly and prove you are competent and deserve to be promoted to better roles.

  When I started (in the same after having a university degree in it), I always had to start at the bottom, in a junior role, on a 3 month temporary contract.  Who got so extended that they identified some new work roles that were needed, and then I had to get one of these new jobs, where I got a permanent role.  Within 18 months, they had sent me on the training, and I was promoted to a role of DBA/programmer, working alongside other programmers and hardware team to manage database servers... everything just because I had shown the ability, willingness to learn and the professional approach to my work.

  Don't think you can just get some training or the qualities of the review, but have no experience and just get into some senior roles or an expert, as most of the companies are wise to such things... they want to know what you have for the roles of the experience.

• Database oracle vs PeopleSoft

  Hi, can anyone please help me by pointing out the difference or any similarity between peoplesoft and oracle database data? I'm naïve then please explain in simpler words, thank you

  This means that you should have only one instance of the peoplesoft application installed on an Oracle server.
  for example. you want to set up a development environment - we must first install database oracle and peoplesoft and then install it. When you install peoplesoft on oracle database, it will load the oracle peoplesoft peopletools tables database that will contribute to the creation of application related PeopleSoft.
  Now if you need an enviornmnet to test, then create another instance of oracle database and leave the name UTL and install the peoplesoft on this application.
  These two will be 2 instances of peoplesoft differenct - development & Testing.

  Hope that clarifies your question.

  do you think that I am ready to go for EM13c with my oracle 12 c 12.1.0.2.0?

  Yes, it is exactly what it says. Actually, I'm just now on a call about the EM13, so I'll come if I hear something interesting that I am allowed to share.

• Improvement of the database from 9i to 11.2.0.4

  Hi all

  I want to upgrade a database independent 9i to 11.2.0.4. Please suggest prerequisites and post the steps of the task to the high-gradation or share a link.

  Can I directly go from 9i to 11.2.0.4?

  Import/Export or Rman which will be better please suggest?

  
  

  Please let us know the steps in the import/export method?

  
  

  Thank you and best regards,

  
  

  Arya
  

  
  

  Arya,

  If you chose to export / import method, you might need to know what is the disadvantage and advantage. If you do the fragmentation of import/export segment will be deleted (it is good), that once we offer the downtime and run two tasks (1.upgrade 2) Fragmentation), but you will need to spend time to complete the upgrade of database.

  You may need to consider your database size and the total downtime you get?

  We will be able to parallelize export and import and finish faster. example, you can split the table export and import / diagram of first level (if you have a PK/FK relationship you need to retain the same).

  Here are the questions in my mind.

  (1) 9i database runs in Server A, you want to upgrade this database on the same server? If so have you checked OS and RDBMS software certification?

  (2) If you want to be updated on the same server by using export / import, then you have enough space to create the new database and to import?

  (3) If you perform import on 11 g that is created on the same server (SERVER A), then you have RAM / CPU to speed up the process?

  (4) you can consider database upgrade (on the same server) using the manual upgrade or DBUA, which has no more than space and your upgrade will of--> current in 9.2.0.8 to 11.2.0.4 version

  (5) manual / DBUA may take time depends on component installed in this database and the invalid invalid objects (if you have very less upgrade then total until 11.2.0.4 can take 2 hours max).

  If you think that you must upgrade the database to the new server, then you may need to review below.

  (a) how the data will be moved to the new server? is where your network speed is good?

  (b) will pass it data before the upgrade? OR after the upgrade to upgrade?

  (c) you can generate waiting for the current version--> that will move data before the end of the upgrade, if once graceful failover you can upgrade of database using DBUA / manual (described in point 5)

  (c) If you want to move the database after upgrade--> you can upgrade the database and build the day before for this in the new database on the new server (this may not be a good option)

  (d) If you want to move database during the upgrade--> you can export and import (this also takes time and your networks in question).

  In my opinion, export and import in a good option if you are very good to have the right amount of downtime and if you want to achieve upgrade and fragmentation at the same time.

  Post your question if you have

  Thank you

  Hi Tomasz,

  The U200 SP comes with two memory slots and is expandable to a total of 4 Gb. RAM modules are available in 256 MB, 512 MB, 1 GB and 2 GB sizes. The RAM modules are normally accessed from the cell below, but for more details I suggest you check your user manual which will have full instructions to know how to locate, remove and replace them.

  Be particularly alert avoid static when you access RAM modules as they are very sensitive and easily damaged.

  . I have connected my phone3g to itunes and it asked if I want to improve, and I agreed. Now, the phone is locked, indicating that my sim card is not supported. What can I do? Can I uninstall the upgrade and bring him back as it was?

  Please help my phone is now dead.

  Thank you

  Your question has already been answered twice. Asking again will not change the answer.

• I want to improve my HP Envy h8-1414

  I want to improve the GPU in my HP Envy H8-1414, but I need to know what cards are supported in the computer. I intend to change the GPU at an AMD Radeon HD 7950 3 GB ddr5 xfx and along with the PSU of 300w for a 430w. So what cards are supported and can be set in this case and the latest games with ease. It is a temporary game as well.

  Hello

  The bad news is that there is not a list of graphics cards for PC.

  Consult this publication documentfor more information.

  Playing the latest games with ease will require a greater than 430 Watt power supply.   You should consider a watt Corsair CX500, or CX600 power.

  Your PC has an update of the BIOS posted, so you must apply the update before using a different video card.
