The Synchronizer has the ability to restart itself automatically in case of failure. This feature should be used carefully as it is undesirable to attempt a restart when the previous failure was caused by as a non-transient error, such as a database instance failure or a Tablespace running out of room.
Automatic restarts are enabled using the
-y
switch:
-yMax[,Wait]
where
Max
This is a positive number and represents the maximum number of restart attempts. A value of zero is treated as "unlimited".
Wait
This is optional and represents the number of seconds to wait before attempting a restart. This can be used as a throttling mechanism to prevent many restart attempts in quick succession. The default value is 0.
We recommend the values
-y10,60
. If the Update Synchronizer fails to restart after the specified number of retries, the error is unlikely to be transient and requires investigation and correction.
