CHANGES
The use of the PARALLEL command line option triggers this issue.
CAUSE
The cause of this problem has been identified in:
Bug:8734963 - ORA-31693 AND ORA-922 OCCURS IN EXPDP WITH PARALLEL PARAMETER.
closed as duplicate of:
Bug:9243068 - EXPDP RETURNS ORA-00922: MISSING OR INVALID OPTION WHEN USING CONSISTENT=TRUE
The cause of the issue is an incorrect PARALLEL value for an external table to be exported when using deferred segment creation.
Bug:9243068 is fixed in RDBMS 12.1.
SOLUTION
To implement a solution for Bug:9243068, please execute any of the below alternative solutions:
Upgrade to 12.1 in which Bug:9243068 is fixed.
OR
Apply patchset release 11.2.0.4 in which Bug:9243068 is fixed.
OR
Download and apply interim Patch:9243068, if available for your platform and RDBMS release. To check for conflicting patches, please use the MOS Patch Planner Tool. If no patch is available, file a Service Request through My Oracle Support for your specific Oracle version and platform.
OR
Do not use the PARALLEL command line option.
BUG8734963導致了報錯，如果要避免報錯，或者禁用parallel，或者打patch，先把patch下下來之後，發現這個patch可以線上apply:
<instance_shutdown>false</instance_shutdown>
<instance_shutdown_message></instance_shutdown_message>
<online_rac_installable>true</online_rac_installable>
該patch僅僅是更新一個pld檔案，並更新了一個package.抽個系統空閒時段，apply patch:
