NAME

tcarecv - Trusted Collective daemon task for receiving newly generated records of critical information

SYNOPSIS

tcarecv blocks_group_number

DESCRIPTION

tcarecv is a background "daemon" task that receives new critical information records multicast by user nodes of the TC application identified by blocks_group_number. It records those assertions in a database for future processing by tcacompile. It is spawned automatically by tcaadmin in response to the 's' command that starts operation of the TC authority function for this application on the local node, and it is terminated by tcaadmin in response to an 'x' (STOP) command.

EXIT STATUS

"0"

tcarecv terminated, for reasons noted in the ion.log file. If this termination was not commanded, investigate and solve the problem identified in the log file and use tcaadmin to restart tcarecv.
"1"

tcarecv was unable to attach to DTKA operations, probably because tcaadmin has not yet been run.

FILES

No configuration files are needed.

ENVIRONMENT

No environment variables apply.

DIAGNOSTICS

The following diagnostics may be issued to the ion.log log file:

tcarecv can't attach to DTKA.

tcaadmin has not yet initialized the authority database for this TC application.
