To abort all Teradata Database transactions for a particular host, after starting aborthost type the following and press Enter:
ABORT HOST nnn
where nnn is the identifier of the host that originated the database transactions you want to abort.
For logon and start requests to a host that has been aborted in this manner, the system displays this error message:
Host quiesced by operator
After running Abort Host, the only way to re-establish host communication with the Teradata Database is to restart the appropriate TDP.
