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 attempting to use a Packaged Solution for my Access 2010 application that has its backend linked to SQL Server. At the moment, I'm using the .accdb file as the frontend, and I would like to distribute my application to some other Windows computers, but the Packaged Solution does not work. I had the package include Access Runtime, so their version of the frontend is running on Runtime and not full Access. However, once the application makes a request to the backend, the application does nothing, as I am not even prompted for the SQL Password as per usual with the full version. I've read on about including a .dsn file in the package can secure the SQL connection (see here), but going through steps of other tutorials to create .dsn files hasn't led to any results. Would anyone know how to correctly generate the .dsn file or if I've done something else wrong at this point?
(And yes, I understanding using Access 2010 in the year 2019 is almost a joke at this point, but I'm doing this for testing purposes. I plan to completely remake the frontend in Angular in the future.)
One other unrelated note... would it be a better idea to have the frontend hosted as a .html file like through the "Publish to Access Services" process? I did read that Access Services was discontinued last year, so would that not be possible?
Edit: This is not a duplicate of "DSN Less Connection (MS Access to SQL2016)" because A) I want to utilize a DSN Connection, not DSN-less and B) I am not using connection strings in my code to hook up with SQL.
You should be able to just create FILE dsn, link your tables, and then distribute the compiled accDE to each desktop.
However, what SQL odbc source provider did you use? If you use the SQL server ODBC provider, then that is by default installed on each computer.
However, if you linked using Native 11 (or later), then that driver is NOT installed on each workstation by default. So, I HIGH recommend you create a FILE dsn (not a user or system DSN), and link the table using that. (Access will create DSN-less links for you)
And you should NOT be seeing a logon prompt with your application. This suggests you forgot or missed the save password option.
So, I would re-link your tables, creating a new FILE DSN. And if you using the linked table manager, then make sure you check the prompt for new location to force creating of a NEW DSN. If you just re-fresh, then you DO NOT get a chance to click on the save password option during the linking process.
So, what odbc driver are you using? The native 11 or later are better, but they are not installed by default on each workstation. However, CAUTION is required here, since the older sql driver does NOT support the newer datetime2 formats. If you used these newer sql column types, they will be returned as string data types in Access and create a mess of issues.
So, first, I would re-link using a FILE dsn.
Make sure you check the save password during the re-link.
You then compile your accDB into an accDE, and then distribute that. You don’t really need to use the package wizard, since once each workstation has the runtime installed, then a simple copy of the accDE to each person’s computer will thus work fine. There is NO special connection between your accDE and the package wizard. Once the runtime is installed, then any and all mdb, accDB, and your accDE can simply be clicked on to launch + run. So for testing, you can skip the package wizard, and just copy the accDE to the target machine, click on it, and see if it works.
Edit
The prompt and check box during this process is this:
So you have to check that box to save the password. Note that you ONLY get this dialog WHEN you create a new FILE dsn.
Hi there hopefully this makes sense.
I have split the database into backend and Frontend.
In the frontend i also have added some linked tables from a SQL Database which are on the network. The DNS files are in the same folder as the front. Now when ive copied across the frontend to the end users desktop when they try to open the table via a form they get the error: "ODBC Call failed" anyone know why that might be?
1 of the end users is using the free version of ms access(2016 runtime) and other has full MS Access but both get the same error.
As it wasnt happening during the development stage on my computer and my collegues. I am a bit lost on how to fix the issue other than convert the linked tables to local tables and do a weekly update of them from the SQL server via my computer where the links work.
Seeing as a normal backend table that is linked to the front works fine. Just would like it to directly call the information from the SQl Server.
Make sure on your development workstation you link the table using a FILE DSN. When you link, Access then converts the links to what we call DSN-less.
The above means then you don’t have to copy or setup or use ANY kind of DSN on each workstation. So do NOT use a “system” DSN – that uses settings in the registry that you have to setup on each workstation.
The next issue to be aware of is which SQL driver you use to link the tables. If you use the “standard” SQL Driver when linking, then you can be SURE those drivers are installed by default on each workstation.
If you use “Native 11” (or later), then you have to ensure that the Native 11 (or later) drivers are installed on each workstation for this to work. The native drivers are better choice, but they are not by default installed on each workstation.
So I suggest you delete the links, or use the linked table manager to re-link the tables – just make sure you use a FILE dsn – since once the tables are linked, then Access ignores and does not use the DSN anymore – you don’t need it, and you could even delete the DSN and you linked tables will still work.
We want to migrate written 4gl programs (with their .per, form files) to Genero Studio so it can be with Windows Forms. How could we create a connection so the .4gl files can retrieve the needed databases? I just want to connect to it, I don't want to copy paste the whole database to my PC. Is there any tutorial step by step? The Genero Documentation is giant and not very clear. Maybe it is if your starting from nothing, but we already have written programs that we just want to make more visual with Windows Forms.
In your Genero Studio configuration, there should be a list of environment sets listed. One of them should be for your backend. Make sure it is configured properly. Then make sure it is checked for your preferred configuration.
There are different ways to connect to a DB, make sure you review the following doc:
http://www.4js.com/online_documentation/fjs-fgl-manual-html/User/Connections.html
From there, I would write a simple BDL program to test:
main
define mystatus smallint
database mydb # this is where you can adapt based on your preferred connection method
end main
Make sure that in your environment set, Debug is check since this will provide SQL driver debug info (FGLSQLDEBUG=9)
From there, check your output panel and see what needs to be configured
When the connection is working, you can extract a schema (needed at compile time) or maybe you already have a schema (.sch file) already created that you simply want to import
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.
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.
