当我们在oracle中导入数据时，报类型如下错误：

此时该怎么办呢？
这时候我们应该先去查询磁盘空间是否使用完，使用命令 df -Th 查询，即
[root@fzoracle ~]# df -Th
Filesystem Type Size Used Avail Use% Mounted on
devtmpfs devtmpfs 16G 0 16G 0% /dev
tmpfs tmpfs 16G 0 16G 0% /dev/shm
tmpfs tmpfs 16G 9.1M 16G 1% /run
tmpfs tmpfs 16G 0 16G 0% /sys/fs/cgroup
/dev/vda1 ext4 79G 75G 315M 100% /
tmpfs tmpfs 3.2G 0 3.2G 0% /run/user/0

使用 lsblk 命令查看根分区，即
[root@fzoracle ~]# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
vda 253:0 0 200G 0 disk
└─vda1 253:1 0 80G 0 part /
vdb 253:16 0 500G 0 disk

磁盘空间不够就需要扩容，具体如何扩请查看这篇文章：https://support.huaweicloud.com/usermanual-evs/evs_01_0072.html#evs_01_0072__section143412109355 鄙人是根据它的相关步骤来进行扩的

扩完空间后，还想继续执行导入，该如何操作呢？
How to restart Datapump

1. 在impdp 命令行下，执行 ctrl + c 来进行 导入任务的停止。

2. 之后再import命令行进行如下操作进行停止
   Import> stop_job=immediate
   Are you sure you wish to stop this job ([yes]/no): yes

3. 修复表空间错误

4. Attach again the job. Check sqlplus>SELECT * FROM DBA_DATAPUMP_JOBS;
   使用类似于"SYS_IMPORT_FULL_*" 的名称

$impdp system/**** attach=SYS_IMPORT_FULL_01
5. 在导入的命令行中输入 start_job ，如下：
Import> start_job
6. Check sqlplus>SELECT * FROM DBA_DATAPUMP_JOBS; It is running again.
