Problem on SQLplus command ""bash: sqlplus: command not found""

Hi all,
i face an error related to my server ""it's running server"" when i use sqlplus command

[oracle@srv1 bin]$ sqlplus
bash: sqlplus: command not found

the data base is up and running i just need to access the sqlplus to import the dump file as a daily backup.

i already check the directory '/u01/app/oracle/product/11.2.0/db_1/bin' and test sqlplus but the same error exist

appreciate any help

Thanks in advanced

also i try to change the permission 777 for sqlplus

Well not found is quite clear...
Whatever shell you use typiing

which sqlplus

should return the path of where the shell found the command/program...
If not there then you have to add the path to the command to your $PATH variable

thanks the problem solved after add the path to $PATH

Thanks in keeping us up to date!

I'm not sure that just setting the path is the right way. Oracle has a script you should source to set the right environment for the instance you're connecting to.
