碰到这个情况，在alert会出现：
LSP0: rolling back apply server 3
LSP0: apply server 3 rolled back
LSP0: can't recover from rollback of multi-chunk txn, aborting..
LOGSTDBY Analyzer process P004 pid=28 OS id=19298 stopped
LOGSTDBY Apply process P009 pid=32 OS id=19308 stopped
LOGSTDBY Apply process P005 pid=29 OS id=19300 stopped
LOGSTDBY Apply process P006 pid=27 OS id=19302 stopped
LOGSTDBY Apply process P007 pid=30 OS id=19304 stopped
LOGSTDBY Apply process P011 pid=34 OS id=19312 stopped
LOGSTDBY Apply process P008 pid=31 OS id=19306 stopped
然后逻辑备库就停止apply，解决方法是重起一下apply，真不行把备库重起一次再开始apply

Applies to:
Oracle Server - Enterprise Edition - Version: 9.2.0 to 11.1.0
This problem can occur on any platform.
Symptoms
You face Logical Apply suddenly aborting. Logical Standby ALERT.LOG shows:
LSP0: rolling back apply server 4
LSP0: apply server 4 rolled back
LSP0: can't recover from rollback of multi-chunk txn, aborting..
LOGSTDBY Apply process P004 pid=25 OS id=176 stopped
LOGSTDBY Apply process P005 pid=26 OS id=179 stopped
LOGSTDBY Apply process P007 pid=27 OS id=183 stopped
LOGSTDBY Analyzer process P003 pid=24 OS id=174 stopped
LOGSTDBY Apply process P008 pid=28 OS id=185 stopped
LOGSTDBY Apply process P006 pid=12 OS id=181 stopped
Cause
In order to reduce Memory Consumption on the Logical Standby Database, large Transactions to be applied are splitted into smaller Pieces (Chunks). Those Chunks can be applied to the Logical Standby Database before the Commit/Rollback has been reached by the LogMiner in the Redo. Once a Chunk is applied, the LCR's belonging to this Chunk get deleted and so the Memory is freed up.
However, sometimes it is possible that such a Transaction is blocking another Transaction. So in this Case, the splitted large Transaction is rolled back in order to let the other Transaction apply.
After that we are missing the LCR's from the already applied, then rolled back Chunks. In order to make the LogMiner being able to read those again, the Logical Apply needs to be aborted and restarted so that the LogMiner can read the large Transaction again (typically starting from the READ_SCN).
Solution
This is not a Bug or Problem. It's just as per the Design of the Logical Apply (see description above).
