[oracle@alpha111 bin]$ oerr ora 1031
01031, 00000, "insufficient privileges"
// *Cause: An attempt was made to change the current username or password
// without the appropriate privilege. This error also occurs if
// attempting to install a database without the necessary operating
// system privileges.
// When Trusted Oracle is configure in DBMS MAC, this error may
occur
// if the user was granted the necessary privilege at a higher label
// than the current login.
// *Action: Ask the database administrator to perform the operation or grant
// the required privileges.
// For Trusted Oracle users getting this error although granted the
// the appropriate privilege at a higher label, ask the database
// administrator to regrant the privilege at the appropriate label.
