用數(shù)據(jù)泵impdp往開(kāi)發(fā)數(shù)據(jù)庫(kù)導(dǎo)數(shù)據(jù)，但導(dǎo)入到INDEX時(shí)感覺(jué)卡住不動(dòng)了

查看導(dǎo)入任務(wù)對(duì)應(yīng)的會(huì)話做在等待什么
SQL> select * from DBA_DATAPUMP_JOBS; OWNER_NAME JOB_NAME OPERATION JOB_MODE STATE DEGREE ATTACHED_SESSIONS DATAPUMP_SESSIONS ---------- ------------------------------ ------------------------------ ------------------------------ ------------------------------ ---------- ----------------- ----------------- SYS SYS_IMPORT_FULL_01 IMPORT FULL EXECUTING 1 2 4 SQL> select sid,sql_id,event from v$session where action='SYS_IMPORT_FULL_01'; SID SQL_ID EVENT ---------- ------------- ---------------------------------------------------------------- 146 bjf05cwcj5s6p wait for unread message on broadcast channel 295 58rzgvcv6gnjs statement suspended, wait error to be cleared
從上面的查詢中可以看到“statement suspended, wait error to be cleared”等待事件，這個(gè)是一個(gè)不常見(jiàn)的等待事件。
繼續(xù)查看alert日志，發(fā)現(xiàn)如下報(bào)錯(cuò)：
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
看到上面的報(bào)錯(cuò)就能明白為什么導(dǎo)入會(huì)卡住不動(dòng)了，正在導(dǎo)入INDEX，創(chuàng)建索引會(huì)使用臨時(shí)表空間，但臨時(shí)文件太小又沒(méi)有設(shè)置自動(dòng)擴(kuò)展導(dǎo)致創(chuàng)建索引語(yǔ)句HANG住。啟用臨時(shí)文件的自動(dòng)擴(kuò)展問(wèn)題解決：
alter database tempfile '/oradata/dbs/temp01.dbf' autoextend on next 100m;
導(dǎo)入正常：
Import> status Job: SYS_IMPORT_FULL_01 Operation: IMPORT Mode: FULL State: EXECUTING Bytes Processed: 843,222,272 Percent Done: 99 Current Parallelism: 1 Job Error Count: 0 Dump File: /home/oracle/dump/wj_dev%u.dmp Dump File: /home/oracle/dump/wj_dev01.dmp Dump File: /home/oracle/dump/wj_dev02.dmp Dump File: /home/oracle/dump/wj_dev03.dmp Dump File: /home/oracle/dump/wj_dev04.dmp Dump File: /home/oracle/dump/wj_dev05.dmp Dump File: /home/oracle/dump/wj_dev06.dmp Dump File: /home/oracle/dump/wj_dev07.dmp Dump File: /home/oracle/dump/wj_dev08.dmp Dump File: /home/oracle/dump/wj_dev09.dmp Dump File: /home/oracle/dump/wj_dev10.dmp Worker 1 Status: Process Name: DW00 State: EXECUTING Object Schema: SUF3TEST Object Name: IDX_ORDER_MEMBER_CHARACTER_ID Object Type: SCHEMA_EXPORT/TABLE/INDEX/INDEX Completed Objects: 407 Worker Parallelism: 1
