Information in this document applies to any platform.
Primary and Logical Standby database are at 22.214.171.124
1) When started logical apply on standby side, it says in the alert.log file that it is waiting for a log :
On primary Db side :
*** 2011-10-09 07:51:17.760
Log read is SYNCHRONOUS though disk_asynch_io is enabled!
2) the archive logs from primary database are properly sent to standby location, but SQL APPLY doesn't apply anything and so it doesn't erase applied redo logs.
