oracle impdp时卡死Processing object type SCHEMA_EXPORT/TABLE/INDEX/INDEX

今天在用impdp导入时，Processing object type SCHEMA_EXPORT/TABLE/INDEX/INDEX卡在建索引的过程一直不动，也不报错，重试了好几遍还是这样。

于是登录到oracle的导入日志查看是什么情况。查看alert日志发现:

statement in resumable session 'SYSTEM.SYS_IMPORT_FULL_06.1' was suspended due to
ORA-01652: unable to extend temp segment by 1024 in tablespace USERS

USERS表空间不足导致的报错，随后加大表空间:

alter tablespace USERS add datafile '/data/oradata/eas/user06.dbf' size 31g

但是导到一半的时候又报错了:

Completed: alter tablespace USERS add datafile '/data/oradata/eas/user06.dbf' size 31g
Thu Apr 30 09:52:04 2020
statement in resumable session 'SYSTEM.SYS_IMPORT_FULL_06.1' was resumed

Thread 1 cannot allocate new log, sequence 12255
Private strand flush not complete
Current log# 2 seq# 12254 mem# 0: /data/oradata/eas/redo02.log
Thread 1 advanced to log sequence 12255 (LGWR switch)
Current log# 3 seq# 12255 mem# 0: /data/oradata/eas/redo03.log

很明显这是日志组被写满了，需要增加日志组:

1、select group#,sequence#,bytes,members,status from v$log;  查看每组日志的状态

GROUP#  SEQUENCE#      BYTES    MEMBERS STATUS
---------- ---------- ---------- ---------- ----------------
         1      16946   52428800          1 INACTIVE    ##  空闲的
         2      16947   52428800          1 INACTIVE    ##  空闲的
         3      16948   52428800          1 CURRENT   ##正在使用的

2、alter database add logfile group 4 ('/opt/oradata/orclbj/redo04.log') size 200M;   增加1组日志组 视情况而定增加日志组的大小。

alter database add logfile group 5 ('/opt/oradata/orclbj/redo05.log') size 200M;

alter database add logfile group 6 ('/opt/oradata/orclbj/redo06.log') size 200M;

3、alter system switch logfile;  切换日志组

4、alter database drop logfile group 1; 删除日志组1  在线增加日志组的时候，删除日志组的时候只能删除 日志组状态为 INACTIVE 的日志组。

随后导入数据成功
