Oracle:impdp导入等待statement suspended, wait error to be
用数据泵impdp往开发数据库导数据,但导入到INDEX时感觉卡住不动了

查看导入任务对应的会话做在等待什么

146 bjf05cwcj5s6p wait
for
unread message on broadcast channel
295 58rzgvcv6gnjs statement suspended, wait error to be cleared
从上面的查询中可以看到“statement suspended, wait error to be cleared”等待事件,这个是一个不常见的等待事件。
继续查看alert日志,发现如下报错:
statement
in
resumable session
'SYS.SYS_IMPORT_FULL_01.1'
was suspended due
to
ORA-01652: unable
to
extend
temp
segment
by
128
in
tablespace
temp
看到上面的报错就能明白为什么导入会卡住不动了,正在导入INDEX,创建索引会使用临时表空间,但临时文件太小又没有设置自动扩展导致创建索引语句HANG住。启用临时文件的自动扩展问题解决:
alter
database
tempfile
'/oradata/dbs/temp01.dbf'
autoextend
on
next
100m;
导入正常:
