搜了一下，網上太多解決方案，最後在MOS上看到如下解決方案，與我的問題極為相似，資料庫版本都是一致的。

The alert logfile shows the following error:

The errors are occasional: if the load is re-run then it is likely that the sqlldr job now succeeds without errors.

CHANGES

You recently upgraded to 11.2.0.4 and are loading data to the database server with SQL*Loader.

The problem is caused by a inconsistency in the SQL*Net layer on the server side, when a data package from the client is read in two different modes (first part in non-fast path mode and second part in fast path mode).
As a result of that, the first part of the package data is lost, resulting in:
ORA-03137: TTC protocol internal error : [12333] [50] [9] [7] [] [] [] []
or
ORA-12592: TNS:BAD PACKET

References:
Bug 18841764 - ORA-12592 TNS:BAD PACKET OR ORA-3137 OR ORA-1 (not a public bug), fixed in 12.2.0.1
Note 18841764.8 - Bug 18841764 - Network related error like ORA-12592 or ORA-3137 or ORA-3106 may be signaled

Other references:
 - ORA-25408, ORA-25402, ORA-12152 AND ORA-12592 AFTER UPGRADE TO 11.2.0.4, closed as a duplicate of Bug 18841764
 - SQL*LOADER FAILS WITH ORA-3137, fixed with fix of Bug 18841764, closed as a duplicate of Bug 18841764
 - ORA-12592 ERRORS AFTER DATABASE UPGRADE TO 11.2.0.4

SOLUTION

1. Confirm that the workaround of Bug 18841764 actually fixes the problem.
Set in the Server side sqlnet.ora file following parameter:

This file is located in the directory: $ORACLE_HOME/network/admin

2. Retest the issue by re-running the SQL*Loader loads.

3. If the problem is fixed, and you need to remove the entry SQLNET.SEND_TIMEOUT from the sqlnet.ora file on the server, then apply  if available for your platform and version (or request this fix from Oracle Support), and re-run the SQL*Loader job.

4. Migrate the solution as appropriate to other environments.
