db2 command not found in unix - unix

I am trying to execute a simple db2 command in Linux command prompt. but Linux command prompt is not recognizing the command it is giving - bash db2 command not found. but db2 is installed in the Linux machine.
command I am trying to execute from Linux command line processor is db2 "create database smaple"
Error I am getting is below "If db2 in not a typo you can run the following command to lookup the package that contains the binary" command-not-found db2 -bash: db2: command not found"
Is this because of environment variable problem ?? or there is only one instance of db2 ie db2inst1 is running in the machine.my user name in appsusr and db2 instance name is db2inst1 are different is this causing problem?? and I am not having super user access.Is this is causing any problem?? do I need super user access is required ??

Just type, echo $PATH in your command prompt , where you can see all the exported paths in your system.
If the db2 path is not found in your environment variable list, then do the following.
export PATH=$PATH:/opt/IBM/db2/V10.1/bin
and then press enter.
I hope this will resolve your issue.

On Linux and UNIX DB2 platforms, the proper way to set your environment variables to run DB2 commands is to source the sqllib/db2profile script belonging to the local DB2 instance owner. That will set not only your PATH but also other important variables that DB2 requires.
In your case, the instance is owned by the db2inst1 user, so your login startup file or batch script should run this command:
. ~db2inst1/sqllib/db2profile
The leading dot is necessary to set the variables in your current shell process, not the sub-process that quickly vanishes after db2profile finishes.

It's more than likely that, if DB2 is installed, it's simply not in your path.
Your path should contain something like:
/opt/IBM/db2/V10.1/bin
which is where the executables live (depending on which version you're running).
Changing your path will probably entail changes to one of the startup files, such as .bashrc or .bash_profile.

Cannot execute sqlite command on remote host via Ansible - [Errno 2] No such file or directory: b'sqlite3'"

I am trying to run a simple query on many servers. I know 100% that the file and directory in question exist.
I can do simple commands, such as ls, pwd, whoami, etc, and I can run the sqlite command on the remote host itself.
The playbook task:
- name: Do a test SELECT statement
become: yes
become_user: root
command: sqlite3 /usr/local/share/sqlite/dbfile.sqlite3 "SELECT * FROM db WHERE hostname="{{ db_server_prompt }}""
register: query_result
- debug: var=query_result.stdout_lines
The error I'm receiving is "msg": "[Errno 2] No such file or directory: b'sqlite3'",.
Is there something wrong with my syntax? Why is it telling me there's "No such file or directory" when using the sqlite3 command? I've tried the absolute path to the executable (/usr/bin/sqlite3), but I get the same error.
I tried to use chdir as an argument per this answer, but I get Unable to change directory before execution. None of these things are working. I would really like to use Ansible, since there are 20+ servers where this is needed.
Update I can run it as an adhoc command:
ansible sqlite_servers_test -m command -a "sqlite3 /usr/local/share/sqlite/dbfile.sqlite3 "SELECT * FROM db_pool WHERE hostname=myhostname" "
What is the difference in trying to run it via a playbook?
If you are working with window and do not want to install sqlite3 permanently (in my case, I just want to update some table fields of *.db sqlite file stored in window, do not want to install sqlite3 at the window), I downloaded sqlite3.exe and copy to window to execute my ansible. After that sqlite3 is deleted from window.

Unable to run sqlplus commands from jenkins

I have a shell script at Unix Server which contain sqlplus commands to do some validation.and I can run script using putty and see required result.In Unix server I have set up Oracle path and Library path in .bash_profile file. So when I start putty , it get loaded and can understand sqlplus command.
Now Challenge is
when I call that shell script from Jenkins(Windows node) then I get error "sqlplus command not found". Here I call .bash_profile file first then my shell script which have sqlplus commands.
Please help.
Set up the PATH as an environment variable in your Jenkins job definition. More details here:

sqlite3 - getting trouble with SQLite3 shell

I am new to SQLite3.
I am trying to create a DB in the shell. When I run the shell, it already shows:
SQLite version 3..
Enter ".help" for instructions ..
Enter SQL...
Enter SQL statements terminated with a ";"
I read somewhere that I should be able to type "$" and codes like "$ sqlite3 mynotes.db"
Now, I need to be able to name my DB (like "mynotes.db") and be able to decide in which folder I want it to be saved.
Can someone help me? Cheers!
The $ somewhere was supposed to be a prompt of some shell (command processor), where you start sqlite3 and specify database name (which is created if does not exists).
If you're running sqlite3 without a shell (by clicking on sqlite3.exe?), it's time to try another way. CMD.EXE on Windows is as good for this job as a typical Unix shell.
As of the folder where the database will be: either cd to this folder before you run sqlite3 mynotes.db, or specify full pathname to the database: sqlite3 "C:\Users\Me\Documents and Settings\mynotes.db" (double quotes are needed when argument contains spaces).
When sqlite3 is started with no parameters, the database will be in memory. Sqlite3 supports "attaching" other databases (see ATTACH DATABASE description). This way, you can create and open on-disks databases even if starting sqlite3 with parameters is impossible for some reason (or too hard).

How to run Unix command from Oracle Forms

OS: UNIX Solaries, Oracle Application Server 10g
To run shell script from Oracle Forms, I used the following host('/bin/bash /u01/compile.sh') and it works well
Now, I need to run unix command something like
host('mv form1.fmx FORM1.FMX') but it's not working
I tried to append the command mv form1.fmx FORM1.FMX' to the compile.sh shell script but also it's not working although the rest lines of the shell script is running well
The solution is to just add the full path of the mv command and it worked well, as follow
/bin/mv /u01/oracle/runtime/test/form1.fmx /u01/oracle/runtime/test/FORM1.FMX
In case anyone else encounters the same problem, the cause is that Forms process creates a subprocess to execute host() command, and that subprocess inherits environment variables of the parent process, which are derived from default.env (or other env file as defined in server config). There is a PATH variable defined in that file, but it doesn't contain usual /bin or /usr/bin, so the commands will not execute unless full path is specified.
The solution is to set the correct PATH variable either in the executed script (via export PATH=$PATH:...) or in default.env. I set it in the script, since, knowing Oracle, there's no guarantee that modifying default.env won't break something.

Windows Command prompt shell for sqlite3

The documentation states that there is a command-line shell for sqlite3:
To start the sqlite3 program, just type "sqlite3" followed by the name the file that holds the SQLite database."
When I try this, in the Windows Command Prompt I get the error message:
'sqlite3' is not recognized as an internal or external command,
operable program or batch file.
Windows explorer reveals several 'Sqlite3" folders in various places:
backends(C:/Python26/Lib/site-packages/django/db)
Lib(C:/Python26)
backends(C:/Django-1.1.1/Django-1.1.1/build/lib/django/db
backends(C:/Django-1.1.1/Django-1.1.1/django/db)
How do I access the shell, can anyone help?
Download sqlite3 binary for windows here. Unzip it and put it somewhere in your path.
That's the error message you get if you try to run any executable that's not in your current directory or in the path.
To correct the problem, find the SQLite executable (SQLITE3.EXE), and run it from the directory in which it resides, or add SQLITE3.EXE to your PATH environment variable.
You have to properly set your PATH environment variable to include one of the locations where sqlite3.exe resides. Usually SQLite seems to set that environment variable upon install but the list of paths where you found it indicates that it just came as a library for various other applications. Therefore it's not too surprising that the path isn't set.
I have sqlite3 on my machine, and as others have mentioned it must be located within a folder specified by your PATH environment variable. Since I use it a lot, I threw it in windows\system32, which is where I place a lot of utilities like pstools.
