Hi:
From the Informix Guide to SQL, SET EXPLAIN:
"If the client application and the database server are on the same machine, the sqexplain.out file is stored in your current directory.
When the current database is on another machine, the sqexlain.out file is stored in your home directory on the remote host. If you do not have a home directory on the remote host, the progroam stores sqexplain.out in the directory from which the database server was started"
