expdp时遇到ora-39097&ora-39065&ora-39079&ora-06512&ora-24033
expdp时各种报错，，我也是醉了，版本为11.2.0.1，expdp命令为：
nohup expdp hq_x1/hq_x1 dumpfile=hq_x1%u.dmp directory=dir1 parallel=8  flashback_scn=10838324803 &
ora-39097: data pump job encountered unexpected error -39079

报这个错往往跟aq_tm_processes=0有关，查看了aq_tm_processes参数，发现果然设置为0，
于是将其set为aq_tm_processes>1的值,问题解决。
