ORA-12154: TNS: unable to handle service name, painful memories ......

When I modify someone else'sProgramAfter the: "ORA-12154: TNS: unable to handle service name" exception, my first reaction was that Oracle's configuration went wrong.

As a result, I had to go around for more than half an hour.

Continue to toss the firewall, 5 minutes, fruitless.

Find answers online, find a lot, and then step by step! Fruitless.

Then I thought about what program or set the path to harmony? The directory is changed and the result is OK. Depressing ~

Later I followed the original path, God! There is a pair of parentheses! Is its error! After the brackets are removed, the original directory can also run normally!

 

Look at my original path!

 
  E: \ work \ k_pbonline \ document \ 040 _ creation \ 047_10 month opening score(Too many threads)\ Users use strongswan
 

Change it to the following.

 

  E: \ work \ k_pbonline \ document \ 040 _ creation \ 047_10 month opening score_ Blank Blank\ Users use strongswan
 

In addition, when the path is too long, there may be some small accidents ~Wine is not afraid of alley depth, good programs are afraid of deep paths!

I hope some friends can help you when they come in.
