Trying to connect Excel 2013 with Oracle - ORA-12154

I am trying to connect MS Excel into Oracle through Data Source ODBC
and im getting error ORA-12154

When I try to connect using ODBC it works find but
when I try to connect using TNS within Excel I get the error:
Message=ORA-12154
"could not resolve the connect identifier"

how to solve it??

here it's

To clarify Hambone's response, to connect Excel to Oracle via Oracle client driver without using TNS Names:

    1.Go to Control Panel > Administrative Tools > ODBC Data Sources
    2.Go to File DSN tab
    3.Choose Oracle driver (e.g. Oracle11gr1)
    4.Provide a name for the new data source (any name)
    5.When prompted for Service Name, enter host:port/servicename e.g. db123:1521/service123

Counter Strike: Source, Closure, Psychonauts And Shank 2 Available On Steam For Linux

After Counter-Strike 1.6 and Half-Life 1, another important game is now available in Steam for Linux: Counter-Strike: Source (CS: S), a popular first-person shooter developed by Valve.

Counter-Strike: Source is a remake of the original Counter-Strike, using the Source game engine, in which the gameplay is basically the same as in the original Counter Strike: the counter-terrorists team plays agains the terrorists in a series of rounds.

Counter Strike: Source

Since both Counter-Strike: Source and Team Fortress 2 use the Source engine, it is likely to see more games using this engine available on Linux, like Half-Life 2 and others.

For now, Counter Strike: Source doesn't show up when selecting Linux for the OS in Steam, but the game is available and can be played on Linux - simply don't select Linux for the OS when searching for it.

There's no news on Counter-Strike Global Offensive (CS:GO), the game released in 2012, but considering the rate at which Valve is making their games available on Steam for Linux, it shouldn't be too long until CS:GO will be available for Linux users.

Psychonauts

Shank 2

Along with Counter Strike: Source, Valve has made some other games available for Linux recently: Closure, Psychonauts and Shank 2 (this one doesn't seem to work right now, according to SteamDB, it's missing the executable), but just like CS: S, they don't show up in Steam for Linux if you restrict the search to Linux.
