Shulou(Shulou.com)06/01 Report--

In fact, this is a very common problem, write it down as a souvenir.

Description:

After 11GR2, the WORKER process of EXPDP and IMDP starts on multiple INSTANCE when setting the parallel parameter, so the DIRECTORY must be on the shared disk. If the shared disk is not set, you need to specify cluster=no to prevent errors.

Tonight is a tough day. We need to synchronize data with ogg tomorrow. Because there is a large amount of data, it will be exported at night, and then imported to other databases at work tomorrow. Therefore, we choose expdp as the synchronization tool. Please refer to the following blog post:

^ C

Thinking about taking a bath, I forgot that this is a set of rac databases and the exported files are not on shared storage, so press ctrl + c to terminate the export immediately:

Export > kill_job

Are you sure you wish to stop this job ([yes] / no): yes

^ CUDE-00001: user requested cancel of current operation

Then add a sentence to re-export, everything is fine:

Cluster=no
