合 在Oracle中，如何彻底停止expdp或impdp进程？
Tags： Oracle故障处理数据泵杀会话expdpimpdp杀进程
👉 本文共约3746个字，系统预计阅读时间或需15分钟。
许多同事在使用expdp或impdp命令时，不小心按了CTRL+C组合键，然后又输入exit命令（或者网络中断等异常现象），导致expdp或impdp进程不存在，但Oracle数据库的会话仍存在，所以dmp文件也一直在增长（或数据一直在导入到数据库中）。
处理过程
在这种情况下的处理办法如下所示：
1、检查expdp进程是否还在
1 2 | ps -ef | grep expdp ps -ef | grep impdp |
若存在，则可用kill -9 process命令杀掉expdp或impdp的进程。
2、杀会话、删表
检查会话是否仍存在，若存在则把相关的会话杀掉（注意：先使用命令“ALTER SYSTEM KILL SESSION '22,33' immediate;”在数据库级别杀掉会话，然后在OS级别使用kill -9杀掉进程），如无杀会话的权限则可以将相关的表DROP掉，表名可以使用如下的SQL来查询：
1 2 3 4 5 6 7 8 9 10 | -- pdb或非cdb SELECT * FROM DBA_DATAPUMP_SESSIONS; SELECT * FROM DBA_DATAPUMP_JOBS; SELECT 'drop table '||d.OWNER_NAME||'.'||JOB_NAME||' purge;' FROM DBA_DATAPUMP_JOBS d where STATE='NOT RUNNING'; -- cdb查询 SELECT * FROM CDB_DATAPUMP_SESSIONS; SELECT * FROM CDB_DATAPUMP_JOBS; |
例如：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | SYS@orclasm > SELECT * FROM DBA_DATAPUMP_SESSIONS; OWNER_NAME JOB_NAME INST_ID SADDR SESSION_TYPE ---------- ------------------------- ---------- ---------------- -------------- LHR SYS_EXPORT_SCHEMA_04 1 00000000A8B71D98 MASTER LHR SYS_EXPORT_SCHEMA_04 1 00000000AB98AFC8 WORKER SYS@orclasm > DROP TABLE LHR.SYS_EXPORT_SCHEMA_04 PURGE; Table dropped. SYS@orclasm > SELECT * FROM DBA_DATAPUMP_SESSIONS; no rows selected SYS@orclasm > SELECT * FROM DBA_DATAPUMP_JOBS; no rows selected |
使用相同的办法也删除从视图DBA_DATAPUMP_JOBS中查询出来的表，直到2个视图无记录。
3、删除导出的dmp文件。
如不删除，则重新执行expdp命令时，会报dmp文件已存在。
使用kill_job停止
如果没有退出expdp或impdp会话，则可以输入kill_job来直接停止导出导入进程也是可以的。
1 2 3 4 5 | expdp \'/ AS SYSDBA\' attach=SYS_EXPORT_SCHEMA_03 Export> kill_job Are you sure you wish to stop this job ([yes]/no): yes |
若是已经退出会话，则也可以通过如下方式重新进入会话：
1 2 3 4 5 6 7 8 9 10 | -- pdb或非cdb SELECT * FROM DBA_DATAPUMP_SESSIONS; SELECT * FROM DBA_DATAPUMP_JOBS; -- cdb查询 SELECT * FROM CDB_DATAPUMP_SESSIONS; SELECT * FROM CDB_DATAPUMP_JOBS; expdp \'/ AS SYSDBA\' ATTACH=SYS_EXPORT_FULL_01 kill_job |
这里的SYS_EXPORT_FULL_01就是DBA_DATAPUMP_JOBS查询出来的JOB名称。
总SQL语句
这里，麦老师给出自己常用的一个SQL语句，可以查询expdp和impdp的相关会话的详细信息，如下所示：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 | SET LINE 9999 COL OWNER_NAME FOR A10 COL JOB_NAME FOR A25 COL OPERATION FOR A10 COL JOB_MODE FOR A10 COL STATE FOR A15 COL OSUSER FOR A10 COL "DEGREE|ATTACHED|DATAPUMP" FOR A25 COL SESSION_INFO FOR A20 SELECT DS.INST_ID, DJ.OWNER_NAME, DJ.JOB_NAME, TRIM(DJ.OPERATION) OPERATION, TRIM(DJ.JOB_MODE) JOB_MODE, DJ.STATE, DJ.DEGREE || ',' || DJ.ATTACHED_SESSIONS || ',' ||DJ.DATAPUMP_SESSIONS "DEGREE|ATTACHED|DATAPUMP", DS.SESSION_TYPE, S.OSUSER , (SELECT S.SID || ',' || S.SERIAL# || ',' || P.SPID FROM GV$PROCESS P WHERE S.PADDR = P.ADDR AND S.INST_ID = P.INST_ID) SESSION_INFO FROM DBA_DATAPUMP_JOBS DJ -- GV$DATAPUMP_JOB FULL OUTER JOIN DBA_DATAPUMP_SESSIONS DS -- GV$DATAPUMP_SESSION ON (DJ.JOB_NAME = DS.JOB_NAME AND DJ.OWNER_NAME = DS.OWNER_NAME) LEFT OUTER JOIN GV$SESSION S ON (S.SADDR = DS.SADDR AND DS.INST_ID = S.INST_ID) ORDER BY DJ.OWNER_NAME, DJ.JOB_NAME; |
