B is not correct answer
B is the correct one.
Use the LAGINFOSECONDS, LAGINFOMINUTES, or LAGINFOHOURS parameter to specify how often to report lag information to the error log. If the lag is greater than the value specified with the LAGCRITICAL parameter, Manager reports the lag as critical; otherwise, it reports the lag as an informational message. A value of zero (0) forces a message at the frequency specified with the LAGREPORTMINUTES or LAGREPORTHOURS parameter.
Use the LAGREPORTMINUTES or LAGREPORTHOURS parameter to specify the interval at which Manager checks for Extract and Replicat lag.
Hi Swall,
A is the correct one (i guess).
The question asks for which parameter “writes a critical message for any Extract/Replicate with a lag over 60 minutes”. As you have stated: “If the lag is greater than the value specified with the LAGCRITICAL parameter, Manager reports the lag as critical”. So, the correct answer is A.
Regards,
B is correct as per Swall’s explanation.
