Career in Database kernel development

How is the career future in Database kernel development, such as index, locking, transaction managements?
It seems to me that the DB kernel is quite stable. Are there many opportunities in this area?
Thanks.

There are only two companies that likely will require those skills in the near future ... Oracle and Microsoft and I would expect they don't hire more than one or two new people a year.
Doesn't sound like a promising direction but if you are truly interested contact Oracle HR in Redwood Shores.

Database App Development VM (Nov 2011) APEX username and password

Does anyone know the Workspace names, usernames and passwords for Instance Admin(Internal workspace), Developers and Users for the latest Database App Development VM (Nov 2011) available from OTN?
The VM forum is very quiet/unhelpful.
NOTE it is NOT
obe/obe/obe
or
oracle/oracle
or
admin/admin
thanks in advance
Paul

OK I followed Roel's suggestion and changed the ADMIN password using the apxchpwd.sql utility. There is no other way as there are no users defined in APEX except the instance administrator ADMIN
MAKE SURE you run V4.1 of apxchpwd.sql as V4.0.1 doesn't work and gives a security error. (Down load APEX 4.1 from OTN then extract apxchpwd.sql from the APEX directory.)
If you now try and connect to APEX and get an error in the browser (firefox) INTERNAL ERROR then shutdown the VM and restart it.
you should then be able to log onto the Instance Administrator as follows:
WS: Internal
UN: ADMIN
PW: <what you changed it to in the apxchpwd>
After you log on you will be asked to provide a new ADMIN password with all the naming restrictions enabled. (these can be turned off later, under manage instance...security settings. Under "Service Administrator Password Policy" change the radio button to "Use policy specified in Workspace Password Policy")
After logging into the workspace manager you will see that the OBE workspace has a status of TERMINATION_IN_PROGRESS5 .
If you want to retain this WS then create the OBE user as a workspace administrator and developer in the OBE workspace. If you set OBE/obe as the UN/PW
then you can log out of the Internal Workspace and log back in as the OBE developer and start application development.
Amazing how none of this is documented in the download! If you don't know much about APEX then you are locked out!

Problem to connect database from Developer 6i

I have downloaded Developer 6i from oracle.com

I was using the forms builder to design forms but while i was trying to connect to database it is saying that "Unable to Connect to Destination"
i was using scott/tiger.

Can anybody help me in solving this problem..
Thank you very much..

How to embed PL/SQL queries in HTML in Database App Development VM?

I'm reading "Learning Oracle PL/SQL" and this book tells me that if I can install apache httpd and modplsql I can embed queries in HTML.
How do I do this in Database App Development VM?
Do I already have apache httpd installed? Is it already started?
If not, how do I start it?
What am I getting when I point my firefox browser to http://localhost:1158/em? I'm getting a nice web page that is prompting for username and password. What username and password do I use? oracle/oracle did not work!
What does this web site do? Administer the database server?
I already tried to use "yum install emacs" as I mentioned in Re: How to Install emacs, openssh and start oracle database and get a connect? and it appears that the repository for "yum" is not correct.
"yum install httpd" does not work either.
When I tried "sudo yum install httpd" it says
"Sorry, user oracle is not allowed to execute '/usr/bin/yum install httpd' as root on localhost.localdomain."
I get the same message for "sudo yum isntall emacs".
Thanks

Database and developer installation

good time for everyone,
i installed my mechine oracle 8i enterprise and i want to use locally, i installed developer 6i . when i want to log in database througth developer i am getting this error ora-12154, could this problem has solution.
thank you your help in advance,

Hi,
You should have installed DB and Developer in different Oracle Homes.
The error should mean that you did not configure properly the DB alias in the Developer Oracle Home.
If you can connect without problems in SqlPlus from the DB Oracle Home, copy the SQLNET.ORA and TNSNAMES.ORA files located in the DB ORACLE_HOME\network\admin to the Developer ORACLE_HOME\network\admin.
Good luck....

Prebuilt Database App Development VM question- make 64bit vm

Hello all i just recently download/deployed the prebuilt Database App Development VM, currently this VM is 32bit, does anyone know how to make this a 64bit vm?

Development is planning on building a new version of this stack from scratch that is 64bit based.
They also want to build a 11gR2 XE based version that will have a smaller footprint.
We will get them out on OTN as soon as they are done.

Database Creation Developer Days SQL Developer 3.1

Hey, I am fairly new to the SQL Developer world, but I am working on building a mock database in the vm prior to building it on a physical server.
The problem I am facing is creating a connection, If I go through new connection, make a name, username, pass, and sid, then click test it sends the error.
Status : Failure -Test failed: Listener refused the connection with the following error:
ORA-12505, TNS:listener does not currently know of SID given in connect descriptor
when I do an sid of orcl it responds:
Status : Failure -Test failed: ORA-01017: invalid username/password; logon denied
then once I change the Use OCI/Think Driver setting it sends out:
Status : Failure -Test failed: oracle.jdbc.driver.T2CConnection.getLibraryVersionNumber()I
Last test I try is creating a local connection, then when I try to click into one of those DB's it request a password, then errors out:
An error was encountered performing the requested operation:
oracle.jdbc.driver.T2CConnection.getLibraryVersionNumber()I
Vendor code 0
I know I'm new, but any help would be greatly appreciated! Thank you so much for your time

Oracle 9i Database and Developer Installation

I am a student going through the Oracle Developer Certification and I am hoping someone can help me with some troubleshooting. This has to do with installing 2 different services on 2 home directories. I installed the Oracle 9i database enterprise edition on the c drive on my laptop. Today I installed the Developer software as well on the c drive on a different directory. I now have the problem that I cannot connect to SQLPlus on the database side and I can not access datatbase connection on the Developer/Form side either. When I installed the developer software I created a new directory called OracNT since it would not allow me to install it on the orahome90 directory (database was installed here)....Does anyone have any advice on what to do? I have install and unistalled both the database and the Developer software and I am getting the same issue...All help would be appreciated.
lari

Lari,
Not quite the right forum for this, but I suspect your tnsnames.ora file in both the
network directories under the two ORACLE_HOMEs does not have an entry
for the local database.
On trying to connect you should get an error message and number. Use these
and search within metalink, there are a number of good articles on network
configuration.
There are also network configuration assistants available from the database windows program
menu.

Unable to establish a connection to Oracle 9I database from Developer Forms

I've installed the Oracle 9I database in the Windoes NT server with SID = ORA9i. Using the SQL*plus coming with oracle 9I database, I can connect to the database. I've also installed the Developer with Forms 6I and Reports 6I in the same computer. I tried to establish a connection to the Oracle 9I from Developer through "Oracle Net8 Easy Config". After giving the settings, when I do a connection test, it is giving the error "TNS Could not resolve the Service Name".
the following is the entry in the 'tnsnames.ora' file
TEST9I.WORLD =
(DESCRIPTION =
(ADDRESS_LIST = ((PROTOCOL = TCP)(Host = ntserver)(Port = 1521))
(CONNECT_DATA = (SID = ORA9i))
Can somebody tell me how to make a connection from Developer (Forms6I and Reports 6I) to Oracle 9I database.
Thank you.

hi matz,
i tried this one too, but it is not working. giving the same error. if i've making a connection thru the 'Oracle Net8 easy config', it is giving the following error at time of connection test.
The test did not succeed.
ORA-03106: fatal two-task communication protocol error
There may be an error in the fields entered
or the server may not be ready for a connection.
You can check the server and retry, or continue.
this is the message i'm getting. but i couldn't find any error in the fields i entered.
if i'm editing the 'tnsnames.ora' file and make the connection, and when i open the Form builder and try to connect to the database, it is giving a memory error.
the instruction at "0x67614f04" referenced memory at "0x000000160". The memory could not br "written".
i don't know why it is happening. i can connect from the same forms to Oracle 8i database. is there any additional settings we need for Oracle 9i on windows platform?
regards
george

Oracle Technology Network (OTN)

If the new VM imported succesfully (shows up in powered off mode), and you still get an internal network error when trying to start up the VM.
Then:
Click 'Ok' to dismiss the error message
Inside your Oracle VM VirtualBox Manager window
Open up the 'Network' settings for the Oracle Developer Days VM
Change your network setting from 'Bridged Adapter' to 'NAT'
click 'Ok' to accept the new network setting.
Restart your Oracle Developer Days VM ,
this should start up fine now and eventually get you to Oracle Linux GUI login prompt,
where you can login as 'oracle/oracle'
When that returns you to the guest desktop, you will have a fully configured 11gR2 database up and running,
The Hands-on Labs (HOLs) can be accessed from Firefox's toolbar menu located on the guest desktop.
