remote shell execution

Hi Can anybody help me on this If I execute ESQL program from server everything is OK, but when try to execute through remote shell from another machine after trying to connect to db had error message 354, -354 Incorrect database or cursor name format. This statement contains the name of a database or a cursor in some improper format. If the statement is part of a program, the name may have been passed in a host variable. Database names should be no longer than 18 characters for OnLine and no longer than 10 characters for INFORMIX-SE (less in some host operating systems). Cursor names must not exceed 18 characters. Both database and cursor names must begin with a letter and contain only letters, numbers, and underscore characters. Starting with Version 6.0, database and cursor names can begin with an underscore. In DOS systems, file names can be a maximum of 8 characters plus a 3-character extension. Env. variable INFORMIXDIR and INFORMIXSERVER are setup properly Thank you Dusan Mijavec
