AUTORESTART
Use the AUTORESTART parameter to start one or more Extract and Replicat processes automatically after they fail. AUTORESTART provides fault tolerance when something temporary interferes with a process, such as intermittent network outages or programs that interrupt access to transaction logs.
You can use multiple AUTORESTART statements in the same parameter file.
To apply this parameter to an Extract group that is created in PASSIVE mode, use it for the Manager that is on the target system where the associated alias Extract group resides. Oracle GoldenGate will send the start command to the source system. If AUTORESTART is used locally for a passive Extract group, it is ignored.
If Manager encounters an out-of-order transaction upon restart, it will not restart Extract. Instead, it will log a warning that notifies you to use the ETROLLOVER option of SEND EXTRACT to advance the trail to skip the transaction that caused the error.
AUTORESTART {EXTRACT | REPLICAT | ER} group_name
[, RETRIES number]
[, WAITMINUTES {minutes | seconds}]

EXTRACT-
Restarts Extract automatically.
REPLICAT-
Restarts Replicat automatically.
ER-
Restarts Extract and Replicat automatically.
group_name-
A group name or wildcard specification for multiple groups. When wildcarding is used, Oracle GoldenGate starts all groups of the specified process type on the local system that satisfy the wildcard, except those in
PASSIVEmode. RETRIESnumber-
The maximum number of times that Manager should try to restart a process before aborting retry efforts. The default number of tries is 2.
WAITMINUTES{minutes|seconds}-
The amount of time, in minutes or seconds, to pause between discovering that a process has terminated abnormally and restarting the process. Use this option to delay restarting until a necessary resource becomes available or some other event occurs. The default delay is 2 minutes or 120 seconds.
RESETMINUTES{minutes|seconds}-
The window of time, in minutes or seconds, during which retries are counted. The default is 120 minutes (2 hours) or 7200 seconds. After the time expires, the number of retries reverts to zero.
