i work for a company as java developer, they gave me laptop that was previously used by another person, to test my java application i need to have oracle on laptop and create some sample database with sample data. when I got the laptop i found that there is oracle installed on it, but i don't know if this is only oracle client or full oracle installation (server + client)
please can you tell me how to figure out if there is only oracle client on laptop or full database installation, plus i need to know if there is some default username and password so that i can access the database and create schema and tables in it, so that i can test my java application.
i thinking to see DBA but i thought of dropping a question here first, maybe i can solve the problem by myself
If it is an Oracle Client, it doesn't have bin/dbca
Oracle Home may indicate the installation's type. The default Oracle Home folder names are:
Oracle Database: dbhome_1
Oracle Client: client_1
Although to make sure, you should check the services looking for OracleServiceSID entry on Windows.
Run Command sqlplus on command prompt.
Check services of windows to know that the oracle database was installed on laptop or not.
Try to find oracle universal installer in all programs by this also you can get which version of database is installed.
Your second question is about default username/password
For this you can give username : "/ as sysdba".
It will not ask for password because it will authenticate thorugh OS authentication.
after login you can able to create new schema or user and tables.
You can check simply using command prompt. Open command prompt and type connect. Provide the username and password and press Enter. It will show "connected" if the database is in your system.
Username: system (default)
Password: (what you provided while installing)
Firstly goto my computer/ this pc and then click on
downloads option and see your app and check that Oracle
is available there or not.

Having an issue getting a SQL Server linked server to Oracle working while using a tnsnames.ora file on a network share.
If I copy the tnsnames.ora file to the local server, the linked servers work fine. However, we keep the file on a network share. My sql service accounts have read access to the share. I configure TNS_ADMIN system variable to the network share, the linked servers no longer work. I get ora-12154: could not resolve the connect identifier specified. tnsping and sqlplus work on the server. When I use process monitor to investigate further, I see:
Operation: createFile
Result: ACCESS DENIED
...
Impersonating: domain\MyLogin
This seems like an issue, but is maybe a false positive? If a process is trying to impersonate my account and access a remote resource it will fail since we don't have Kerberos configured to handle double-hop.
SQLPlus and TNSPing work just fine with the network share configured.
I've looked at this post and tried the items that seemed relevant, but had no success.
Additional Info:
sqlnet.ora has this:
SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
I am able to open a file browser as a service account and open the tnsnames file.
I had this same issue while trying to connect a oracle 10g database via my WCF serivce developed in .NET 4.0 framework.
I was having multiple instances of ORACLE installed in my system. So, I modified the ORACLE_HOME to point to the Oracle 10g and it worked.
Also check the following:
Your service name might have an alias, so Make sure that your listener is listening for the same service name that you are using and check for both local and global entries. Check:
$ORACLE_HOME/network/admin/tnsnames.ora
Check your global_name setting with this SQL:
select * from global_name;
Also, Please make sure you add the Key TNS_ADMIN in the registry and create a enviroinment variable with name TNS_ADMIN
Regedit->HKEY_LOCAL_MACHINE->Software->Oracle->RightClick NEW->StringValue and name
Specify the correct path where the oracle is installed for Example
X:oracleproduct32bit10.0.1.0.0NETWORKADMIN
Edit
The below video also looks quite helpful. Please check.

As an Oracle DBA I sometimes have to work with Windows. Maybe you can adopt from my experiences with Oracle on Windows.
Scenario:
An Oracle DB runs under a domain user. I want to restore a database from a backup which is located on a Windows share (sounds like "read" but it obviously isn't). I (or let's say the windows team) did not manage to find the proper way to grant the required permissions.
After many tries, the admins grant "everything" to the entire Oracle server.
Even though the Oracle process runs in a user context we did not find a set of permissions for the user only. Only the permissions for the entire server enabled the restore process to access the data.
From security point of view this is a horrible solution! But maybe it will help you to come closer to a solution (and if so, please share :-)).
I have a problem with my database. I installed postgreSQL 9.5 on my Ubuntu server. I changed the postgresql.conf file to allow binding the postgreSQL server to the localhost. This allows me to run pgAdmin and connect to my database by forwarding also the port 5432, where I run my postgreSQL.
The problem I am experiencing is that I only see the default table 'postgres', but not my newly created one 'games' (I created this table by running create database games with the postgres user connected to the server).
And here is my screen shot of the pgAdmin application with all the property value I use to connect to my server.
As you can see from the first picture I use the same permissions as for the postgres database - it is blank, which should grant access to everyone. I know I have to change that later and limit it to the postgres user I have, but for now I will let it that way. Once I manage to see my 'games' database, then I will start to tighten the security more.
UPDATE I granted all access to the database 'games', which is visible right on the third screen shot down. The access privilege is different. This did not help me, I would still not see the database, when connecting to the server with pgAdmin. A saw someone had a similar problem and run the right click on the server and clicked 'New database'. This seems created a new database, because as you can see from the pgAdmin, the application manage to find the score table I create inside pgAdmin. The reason I believe this is the case is, because running the same SQL connected to the server postgres=# select * from score; results in ERROR: relation "score" does not exist LINE 1: select * from score;.
I manage to find the problem. One of my problems was that I had (unaware of that) installed a postgreSQL server on my machine. Seems I installed it with my pgAdmin install. So everytime I would connect to my server, I would establish a connection to my localhost server and not my remote server. So I just uninstalled the server and installed only the pgAdmin client.
The second problem I had was that the file /etc/postgresql/9.5/main/pg_hba.conf had to be changed. So I run:
sudo vi /etc/postgresql/9.5/main/pg_hba.conf
and changed the line
# Database administrative login by Unix domain socket
local all postgres peer
to
# Database administrative login by Unix domain socket
local all postgres md5
Once that was changed, I had to restart the configuration by executing:
sudo /etc/init.d/postgresql reload
I would also point out that it is important to have postgres user as a unix and DB user with same passwords. I found all this information here.
Try granting access privileges explicitly for your new table.
I believe a blank access privileges column means the table has DEFAULT access privileges. The default could be no public access for tables, columns, schemas, and tablespaces. For more info: http://www.postgresql.org/docs/9.4/static/sql-grant.html
I need to install an ODBC database on a few computers and was hopeing to do it all via a batch file. I can get it to install the database connection string like so.
ODBCCONF.exe CONFIGSYSDSN "SQL Server" "DSN=DSNNAME | Description=Descriptionname| SERVER=ServerName | Trusted_Connection=Yes | Database=dbname"
pause
#CLS
#Exit
But i need to add that it should log in with with an Login ID and password NOT with the network login ID.
Anyone know how i can fix this?
also its on 64 bit windows 7
Thanks
http://social.msdn.microsoft.com/Forums/en-US/sqldataaccess/thread/53f689c1-53c8-45c6-b9ce-c44bce46cd9d/ says "Persistence of login credentials in a DSN is not supported (it's insecure). Using trusted connection would be the best way to achieve connecting without specifying credentials since the logged on user credentials is used for authenticating to the server."
If you change to Trusted_Connection=No it will add the DSN, but you'll then need to run the ODBC Data Source Admin and add the user and pwd to the new DSN by hand.
btw, according to http://msdn.microsoft.com/en-us/library/windows/desktop/ee388579%28v=vs.85%29.aspx "ODBCCONF.exe will be removed in a future version of Windows Data Access Components. Avoid using this feature, and plan to modify applications that currently use this feature."
I installed db2 client in my system for personal use. I am not able to understand from where to create the database so that i can create tables on that db and play around with sql queries as of now.
This is totally related to my personal use and learning purpose.
Please inform how to create a dummy database and play around with it with db2 client?
Regards,
Are you on Windows? Are you using DB2 Express-C? I'm assuming you are, since you say this is for personal work.
After you have the DB2 binaries installed, you should have been prompted with the "DB2 First Steps" application, where you could have the application go through a GUI to create the database for you. If you missed it, you should be able to find it in your start menu with Start -> Programs -> IBM DB2 -> DB2COPY1 (Default) -> Set-up Tools -> First Steps.
If you prefer the command line, you can use the following:
First, determine if your installation created a default instance (on Windows, this will be called DB2) by using the db2ilist command. In the DB2 Command Window, if you're not on the instance you want to create a database in, you can switch with the following command:
set db2instance=DB2
Be sure to not include spaces around the equal sign.
Now, in order to create a database in the current instance, you use this command:
db2 create database mydatbase
For further reading, IBM has produced a Getting Started ebook, and I would highly recommend you check it out!
The DB2 client is just that - a client only. It does not include the database engine.
To create a database you have to install the server. The server includes the client portions.
I am a software developer with devlopment experience in C#, C++ .Net alongwith SQL Server 2005/08, Oracle and mysql. But somehow i dont get jBASE to work at Windows XP SP3 machine.
My goal is setup user accounts, create database on a JBASE ainstallation, authenticate and backup/restore few table via a C++ program. And i dont need to do it with builtin backup/restore tools of jBASE.
I am able to install jBASe 4.1 aling with all its accessories on my WINXPSP3 machine. I was able to run the jSlimserver and TEMENOUS server along with licnesing server. I was able to add the license key as well. But after that what i was supposed to do? i have no idea about it.
The docs and online help doesnt answer a simple question of how to create a database! The google search results from the jbase site all go to the 404 Pages!
Can a jBASE expert guide to the following steps:
Create a jBASE database.
Create users
Authenticate via those users
Connect to database
Create tables and insert data.
Connect via a C++ or C# program to connect to jBASE DB and backup/restore tables.
I know that this is too much too ask but i dont get to get the JBASE system. I cant get it to work on my System somehow. Btw, jdc and jexloree doesnt seem to do anything. I have checked that enironmental variables for jBASE are setup correctly and i have verified them. There are no extra JRE or JDK installations on my system. Besides all that, only licensing client, slim server and temenous server seem to run and listen for connections and no other execuatable ever seems to work.
A simple tutorial to achieve the objective will be highly appreciated. Also if anyone can point out the mistake that i have done or anything i might need to check, then please do so. I will be highly encouraged and obliged.
Thanks
Steve
I hope this will help, if you have not already found a why to do this.
Setup jBase User and Database
Create a Security Group called
'Jbase' or what every you want to
call it
Add a User to this group. I would
recommend adding your administrator
user to it as well
Create a folder in you file system
to save the database information
into
Assign the 'Jbase' Security group to
the folder, and give it "Full"
read/write/execute access.
Creating the database:
Make sure the current users you
are logged on with is the 'Jbase'
security group.
go to the command prompt, and CD
to the folder you create to store
the database
run the jShell 'jsh' from that
location
use CREATE-FILE to create the
files/tables you want to store your
information in.
Inserting data:
There are several ways to enter data. You can use ED, your can your programming environment, or you can create a quick MultiValue/jBase compiled server script to ask for the data and write them to a file/table.
