Of course you have an SQL script: The SQL command:
Code:
ALTER SESSION set container='new_container';

is one line in that SQL script. All of the commands being processed by the sqlplus command you are invoking constitute an SQL script!

pvm_setsbuf

SETSBUF(3PVM)							  PVM Version 3.4						     SETSBUF(3PVM)

NAME

       pvm_setsbuf - Switches the active send buffer.

SYNOPSIS

       C    int oldbuf = pvm_setsbuf( int bufid )

       Fortran	 call pvmfsetsbuf( bufid, oldbuf )

PARAMETERS

       bufid   Integer the message buffer identifier for the new active send buffer.  A value of 0 indicates the default receive buffer.

       oldbuf  Integer returning the message buffer identifier for the previous active send buffer.

DESCRIPTION

       The  routine  pvm_setsbuf  switches the active send buffer to bufid and saves the previous active send buffer oldbuf.  If bufid is set to 0
       then the present active send buffer is saved and no active send buffer exists.

       The routine is required when managing multiple message buffers.	For example switching back and forth  between  two  buffers.   One  buffer
       could be used to send information to a graphical interface while a second buffer could be used send data to other tasks in the application.

EXAMPLES

       C:
	    sbuf1 = pvm_setsbuf( sbuf2 );
       Fortran:
	    CALL PVMFSETSBUF( NEWBUF, OLDBUF )

ERRORS

       These error conditions can be returned by pvm_setsbuf

       PvmBadParam
	      giving an invalid bufid.

       PvmNoSuchBuf
	      switching to a non-existent message buffer.
