According to the GG documentation:
"Performance testing also confirmed that the logmining server runs faster when _log_
buffer_size is set to 128 (the default is 8) when the source database runs in a system
with high redo volume. To set this parameter, use the following command.
SQL> alter system set _log_buffer_size=128;"
Is _log_buffer_size a typo? If not where is the parameter? If it is a typo what is the parameter?
Thanks,
