How to Install emacs, openssh and start oracle database and get a connect?

As suggested by another poster, I installed the prebuilt appliance at [http://www.oracle.com/technetwork/community/developer-vm/index.html] and [http://www.oracle.com/technetwork/server-storage/virtualbox/downloads/index.html] with the intent of running oracle database in a linux vm as a guest on windows 7 and connecting to it using JDBC from the windows host.
This is running but I don't know how to install other stuff. I tried "sudo yum install openssh" and "sudo yum install emacs" and "sudo service sshd status" and none of these worked (it could not find these packages). I could not get apt-get or app-get or aptget to work either. I was hoping that "uname -a" would tell me if this was fedora or debian or something else but no luck. What command do I use to learn the distro name?
How do I make ifconfig tell me what the ip address so I can use "scp" and "ssh" to get into the box? Ok, /sbin/ifconfig works and I see there is only a loopback address. Ack! How do I create a socket so I can ssh into this little beastie?
How do I disable the firewall or (better yet) punch holes in it so I get use JDBC and ssh, scp and samba from windows 7?
I tried firing up the SQL Developer 3.1 and getting a test connection with username and password of "oracle" with no luck. How do I get a test connection to work?
How do I determine if the database is running? If not, how do I start it and stop it and restart it?
Thanks
Siegfried

There is no "oracle" account native to the database itself. This is just the default account that owns the application. Log on as oracle/oracle to the OS. (OEL) You can change the passwords of the sys and system account by setting your $ORACLE_HOME and $ORACLE_SID. Default SID is orcl on a database install. Also set a path to the oracle binaries in the form of $ORACLE_HOME/bin.
Then sqlplus / as sysdba
Change passwords of sys and system using the following example.
ALTER USER SYS IDENTIFIED BY [password];
ALTER USER SYSTEM IDENTIFIED BY [password];
The supplied appliance runs oracle enterpirse linux. Not debain or fedora.
Why do you need "emacs"?
I haven't personally load this appliance with Virtual Box but there has to be a readme file somewhere that details all the passwords and etc.

How to let SOA Suite automatically start Oracle Database services if necess

It occurs from time to time that I forget to start Oracle database services
before I start Soa Suite. Can I somehow let SOa Suite startup script check in advance
if Oracle database services need to be started (and start them automatically if necessary)?
Peter

Hi,
This is a familiar issue. I've come up with the following solutions.
1) On my linux machine, I start the database (EE) and soa suite at boot time using /etc/oratab.
2) On my windows machine, I start the database (XE) at boot time, as a service that automatically starts. The soa suite is started manually. I could start the suite automatically as a service also, but because it takes up so much memory and I do not always want to run the suite, I prefer to start manually. In any way, the database is started automatically before the soa suite.
Hope this will help you.
Kind regards,
H

How-To install SOAP Client Stack in Oracle Database

Hi,
1. i wrote a java clientstub that accesses a webservice.
2. all works fine if i run it from within java.
3. i then tried to port it to oracle database.
4. loading the java classes defined in the sample code works fine too.
5. i then loaded my client (wrapper and client-stub) classes and made pl/sql procedure from the wrapper.
6. i try to access the webservice
the problem:
1. if i made step 5 in SYS-SCHEMA all is ok
2. if i made step 5 in an other SCHEMA i got an exception in step 6:
java.lang.NoClassDefFoundError
the code line is pointing to: m_httpConnection = new OracleSOAPHTTPConnection();
this is located in the client-stub class constructor
there exist synonyms of all classes in the public schema.
is it a problem with priviledges, and if what priviledges are required?
if this isn't the best way to access webservices from within oracle database, what other solutions are possible?
if more information are required, please let me know
thanks
ralf

Hi,
Refer to this document for information on loading SOAP jar files to the database.
The database schema you are using needs to be granted the following permission to access the external web service
execute dbms_java.grant_permission('<dbuser>','SYS:java.net.SocketPermission','<host-name>:<port>','connect,resolve');
where, <host-name> and <port> point to the location where the webservice is running. If you are behind a firewall, use the proxy host and port here.
For more information on accessing external web service from the database refer to the samples on the Database Web Services Page

Where to download and how to install X Window System for Oracle Linux 5 ?

Folks,
Hello. I am using Oracle Linux 5 and Oracle Database 11g for PIA.
Before install Oracle DB 11g into Oracle Linux 5, we need to install X Window System according to the document page 2 http://download.oracle.com/docs/cd/B28359_01/install.111/b32285.pdf
But I don't know where to download and how to install X Window System for Oracle Linux 5.
Can any folk provide a link to download X Window System and tutorial to install it for Oracle Linux 5 ?

You can address the problem in a number of different ways.
You can install X-windows from the installation DVD or setup access to the Oracle public software repository as described in http://public-yum.oracle.com. In which case, the command to install X-windows is: yum groupinstall "X Window System"
Or, you login remotely and and use SSH with X-forwarding, in which case the software on the server will use the X-Windows server on your client system. This is probably the preferred way since you do not have X-windows installed on the server. For more details about SSH forwarding and howto, please see Install Oracle 11gR2 on Ubuntu Linux 11.04 (64-bit) Howto part 2 Oracle Universal Installer.

Installing Oracle Database and SQL Developer

Hi, I was looking for some help/advice in regards to installing an Oracle Database and SQL Developer onto a Windows 7 32bit machine. I have been asked to create a database to store data that I create through reports in Excel so I am required to create a local database but not sure how to go about doing this. Also not sure if I install the Express Edition or Oracle Database 11g R2. If somebody could please advise on how I can get this started or even any links/tutorials that would guide me in how to get this installed with a localhost.
Thanks in advanc.

Thanks guys, I have managed to install Oracle 11gR2 and I have setup a database using the dbca tool and I can connect to my new database. One thing that I have noticed is that when i look into my tables in sql developer i see loads of different tables i.e. def$_, logmnr_, etc and I am not sure why this is as I expected an empty tablespace.
Thanks btw for all your help.
One of the key principles of relational databases is that they use their own facilities to manage themselves. That means the database management system uses the database to manage data about the database using exactly the same facilities (tablespaces, tables, user accounts, procedures, etc) that an application uses to keep data for the application. See "data dictionary" So there is no such thing as a completely empty database.
As said by others, you do NOT want to be creating your own tables under oracle's schemas (users) or in oracle's own tablespaces (esp. SYSTEM and SYSAUX). Create your own user account/schema. Create your own tablespace. Make that tablespace the default for that user.

How can I change the hostname after Oracle Database XE is installed?

I currently have XE installed and working on my ubuntu machine.
When I change the hostname of my machine, oracle database no longer connects and says "ORA-12505, TNS:listener does not currently know of SID given in connect descriptor".
Can anyone tell me how I can change the hostname of my machine and keep oracle database working correctly?
Thanks

Stopping, reconfig, starting the instance is one way, although that is somewhat like using petrol to kill ants.
The database instance pretty much does not care about the hostname setting. But the listener does- the installer finds the hostname and uses that in the setup bits.
As posted somewhere here, when using the 1521 default listener port, the listener.ora config file can just be moved out of the way. Another potential fix is setting the HOST=0.0.0.0 for the IPv4 "any IP" address setting, or setting it to the correct hostname. Or HOST= can be set to IPv4 address. For IPv6, have to use HOST=<hostname> and it must resolve, can't HOST=... an IPv6 address.
To move the listener file, stop the listener first. To change a HOST=... setting, also stop the listener first.
lsnrctl stop
mv $ORACLE_HOME/network/admin/listener.ora $ORACLE_HOME/network/admin/listener.bk0
# or
vi $ORACLE_HOME/network/admin/listener.ora
# change HOST=<whatever> to the correct value, or 0.0.0.0
lsnrctl start
sqlplus /nolog
conn system
... password ... Connected.
alter system register;
exit
# start the lsnr
lsnrctl start
# check the status, services
lsnrctl stat
lsnrctl serv
If the host has a wireless (or another NIC) that one does not want to offer up remote connections on, the 0.0.0.0 is not a good way to go either

How to stop and start RAC Database

Hi,
Can anybody tell me How to stop and start RAC Database.
Pls give me the exact procedure for OS - IBM Aix 5.3.
Rajkumar

Burleson,
It so appears, as from the numerous times you have been published incorrect, untested information, and non-working scripts, you are not an Oracle guru,
but only a self-proclaimed one.
It also appears nothing on your 'CV' can be easily verified.
You state you are an 'adjunct professor emeritus', however anyone who was kicked out after a few months can call himself a 'professor emeritus'.
Looking at the enormous amount insults and slander you have posted directed to me and others on this forum, showing a highly unprofessional attitude toward your peers,violating this forums rules of conduct, don't you think you deserved to be banned completely?
After all, you are always promoting your own publications here, which is also in violation of the rules for this forum.
What makes you think that "Sybrand" is a man's name? How many male Sybrand's do you know? I don't know any, not one.
That's your problem. I'm as much as male, as you are a fat, ugly, self-proclaimed Oracle-guru, which you are clearly not, you are only a fraud, and this glares from all of your publications.,

How to load PDF files into oracle database and display them in APEX

Hi All,
We have a requirement for loading the Loading PDF files (lots of PDf files) to the oracle database and then display the PDF files in the Oracel APEX report.
So that User can view the PDF files. Our current APEX verison is 3.2..
Please let me know how to implement it and where to find the sample application!
Thanks in advanced!
Jane

Thanks Tony for your quick response!
We need to load a lot of PDfs (history + current).
I have a questions about the SQL loader. I am trying to insert a pdf file into a table by following the oracle loading sample:
http://download.oracle.com/docs/cd/B10501_01/text.920/a96518/aload.htm
Example Data File: loader2.dat
This file contains the data to be loaded into each row of the table, articles_formatted.
Each line contains a comma separated list of the fields to be loaded in articles_formatted. The last field of every line names the file to be loaded in to the text column:
Ben Kanobi, plaintext,Kawasaki news article,../sample_docs/kawasaki.txt,
But i don't know to where should I put my pdf file on the server.
for example:
,../sample_docs/kawasaki.txt,
Where is the file 'kawasaki.txt'??
I try my local path, it didn't work. like c:\temp.
then I loaded teh PDf file into our server(/findev20/olmtest/orafin/11.5.7/olmtestcomn/temp) , and In my data file. I put the path
1, pdf_emp1,../findev20/olmtest/orafin/11.5.7/olmtestcomn/temp
but I got the error: the system can not find the file specified.
Where should I put the PDf files on the server and how to specify the path in the data file?
Thanks!

Script to Stop and Start Oracle Meter Data Management

Hi,
This is my first post in Oracle forums so if i open this in the wrong thread please forgive me.
I tried to create a windows batch script to stop and start Oracle Meter Data Management but i can´t.
@echo off
D:\spl\MDMDEV\bin\splenviron.cmd -e MDMDEV
D:\spl\MDMDEV\bin\spl.cmd stop
D:\spl\MDMDEV\bin\splenviron.cmd -e MDMDEV
D:\spl\MDMDEV\bin\spl.cmd stop
The batch exits in the first command and i can´t understand why.
Another thing is if i use spl.cmd stop command it doesn´t do nothing, is this normal?
Thanks in advanced for all replies.
Best Regards.
Nuno

I had to put a call command in mine. I think it is because you are trying to run a .cmd file within your bat file. You're actually changing shells. Thats why you need the call.
call d:\spl\mdmdev\bin\splenviron.cmd -e mdmdev
call d:\spl\mdmdev\bin\spl.cmd start
I actually set mine up to use variables so all I had to change from script to script was the environment...
<snip>
SET SPLENV=MDMDEV
SET INSTALLDRIVE=D:
SET INSTALLDIR=SPL
SET BINDIR=%INSTALLDRIVE%\%INSTALLDIR%\%SPLENV%\bin
%INSTALLDRIVE%
cd %BINDIR%
REM Set envornment
call %BINDIR%\splenviron.cmd -e %SPLENV%
REM Wait a few seconds for environment to setup
ping localhost -n 5 > nul
REM Start SPL Web
call %BINDIR%\spl.cmd start
</snip>
I was unable to find a way to get this to run as a service. Have you?
I'm currently running these scripts in the startup/shutdown script section of the local machine policy (gpedit.msc).

Where should one install Oracle Database and the Grid Infrastructure in order to adhere to OFA?

I've downloaded the two zipped install folders for Oracle Database, and the two zipped install folders for the Grid Infrastructure. The book I'm following for installation says to use one directory for the database, and one directory for the Grid Infrastructure, but it doesn't explain where they should be located in OFA. Presumably they should both end up somewhere in the same Oracle Base (since everything Oracle related on a single file system should go in the same base, according to my understanding), but it isn't clear where they should be installed in relation to each other. For example, is the Grid Infrastructure a separate product that gets its own Oracle Home? Can anyone shed light on this process?
Also, does it matter to which location the zipped files are unzipped? For example, are any of these files used after the installation process, or does OFA only care about post-installation location?

I think this links may be helpful -- ORACLE-BASE - Oracle Database 11g Release 2 RAC On Oracle Linux 5.8 Using VirtualBox, http://www.oracle.com/technetwork/articles/hunter-rac11gr2-iscsi-088677.html.
OFA -- Optimal Flexible Architecture standard. The standard is a set of configuration guidelines created to ensure well organized Oracle installations that are easier to maintain (http://docs.oracle.com/cd/B28359_01/install.111/b32002/app_ofa.htm#LADBI440).
It relates to location of the grid and dbms files location. Actually you should specify base directory and follow installer. System will be installed in correct directories.
It does not matter where you will unzip your distributives. You may delete them after installation to free space.

How to install Snow Leopard on Macbook Pro? keep getting msg- cannot install Internal HD is used for Time Machine- this was reset to external HD and still get msg?

At some point, your internal HD was selected for use as Time Machine backups, and a Backups.backupdb folder was created at the top level. So OSX thinks you're trying to install it on the same drive as your backups.
Open your internal HD with the Finder (you won't find it via a Spotlight or Finder search) and delete that folder.
