前天，业务反应数据库不能连接
在操作系统通过字符串尝试登陆数据库报：ORA-00257: archiver error. Connect internal only, until freed
解决思路：
1.操作系统清理归档
2.rman清理expired归档
遇到日志不能切换，且归档目录未满的情况，且数据库不能正常关闭的解决思路：
1.查看log group 状态，如果处于inactive状态但是报需要归档的错误
2.强制clear未归档的日志
3.删除clear的日志组，并重建
4.如果还不能switch logfile，重启数据库
详细步骤如下：
查看alert日志：
*********************************************************************** Fatal NI connect error 12170. VERSION INFORMATION: TNS for HPUX: Version 11.2.0.3.0 - Production Oracle Bequeath NT Protocol Adapter for HPUX: Version 11.2.0.3.0 - Production TCP/IP NT Protocol Adapter for HPUX: Version 11.2.0.3.0 - Production Time: 17-MAR-2015 17:28:08 Tracing not turned on.

哦，原来是归档满了
1.数据库查询归档位置：
SQL> archive log list Database log mode Archive Mode Automatic archival Enabled Archive destination USE_DB_RECOVERY_FILE_DEST Oldest online log sequence 5 Next log sequence to archive 5 Current log sequence 7 SQL> show parameter db_recovery_file_dest NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ db_recovery_file_dest string /Oracle/apps/oracle/recovery db_recovery_file_dest_size big integer 4977M SQL> select * from v$recovery_file_dest NAME SPACE_LIMIT SPACE_USED SPACE_RECLAIMABLE NUMBER_OF_FILES -------------------------------------------------- ----------- ---------- ----------------- --------------- /Oracle/apps/oracle/recovery 5218762752 4405968896 0 3
2.进入操作系统，手动删除所有归档
3.rman检查并清理归档
RMAN> crosscheck archivelog all; using target database control file instead of recovery catalog allocated channel: ORA_DISK_1 channel ORA_DISK_1: SID=235 device type=DISK validation failed for archived log archived log file name=/Oracle/apps/oracle/recovery/GJJS/archivelog/2015_02_03/o1_mf_1_2_bf1o3ohr_.arc RECID=1 STAMP=870732036 validation failed for archived log archived log file name=/Oracle/apps/oracle/recovery/GJJS/archivelog/2015_02_12/o1_mf_1_3_bfqxh0sz_.arc RECID=2 STAMP=871461477 validation failed for archived log archived log file name=/Oracle/apps/oracle/recovery/GJJS/archivelog/2015_02_19/o1_mf_1_4_bgcv464n_.arc RECID=3 STAMP=872114452 Crosschecked 3 objects RMAN> list expired archivelog all; List of Archived Log Copies for database with db_unique_name GJJS ===================================================================== Key Thrd Seq S Low Time ------- ---- ------- - --------- 1 1 2 X 28-JAN-15 Name: /Oracle/apps/oracle/recovery/GJJS/archivelog/2015_02_03/o1_mf_1_2_bf1o3ohr_.arc 2 1 3 X 03-FEB-15 Name: /Oracle/apps/oracle/recovery/GJJS/archivelog/2015_02_12/o1_mf_1_3_bfqxh0sz_.arc 3 1 4 X 12-FEB-15 Name: /Oracle/apps/oracle/recovery/GJJS/archivelog/2015_02_19/o1_mf_1_4_bgcv464n_.arc RMAN> delete expired archivelog all; released channel: ORA_DISK_1 allocated channel: ORA_DISK_1 channel ORA_DISK_1: SID=235 device type=DISK List of Archived Log Copies for database with db_unique_name GJJS ===================================================================== Key Thrd Seq S Low Time ------- ---- ------- - --------- 1 1 2 X 28-JAN-15 Name: /Oracle/apps/oracle/recovery/GJJS/archivelog/2015_02_03/o1_mf_1_2_bf1o3ohr_.arc 2 1 3 X 03-FEB-15 Name: /Oracle/apps/oracle/recovery/GJJS/archivelog/2015_02_12/o1_mf_1_3_bfqxh0sz_.arc 3 1 4 X 12-FEB-15 Name: /Oracle/apps/oracle/recovery/GJJS/archivelog/2015_02_19/o1_mf_1_4_bgcv464n_.arc Do you really want to delete the above objects (enter YES or NO)? yes deleted archived log archived log file name=/Oracle/apps/oracle/recovery/GJJS/archivelog/2015_02_03/o1_mf_1_2_bf1o3ohr_.arc RECID=1 STAMP=870732036 deleted archived log archived log file name=/Oracle/apps/oracle/recovery/GJJS/archivelog/2015_02_12/o1_mf_1_3_bfqxh0sz_.arc RECID=2 STAMP=871461477 deleted archived log archived log file name=/Oracle/apps/oracle/recovery/GJJS/archivelog/2015_02_19/o1_mf_1_4_bgcv464n_.arc RECID=3 STAMP=872114452 Deleted 3 EXPIRED objects
4.改变归档目录，是归档不放入闪回目录中
alter system set log_archive_dest_1='location=/Oracle/apps/oracle/arch';
OK
到这里，归档空间已经清理完成，但是在操作系统上再次测试的时候依然报ORA-00257: archiver error. Connect internal only, until freed，很奇怪~~
尝试数据库中切换日志
SQL> select group#,sequence#,status from v$log; GROUP# SEQUENCE# STATUS ---------- ---------- ---------------- 1 7 INACTIVE 2 8 CURRENT 3 6 INACTIVE SQL>alter system switch logfile; ----夯住不动，alert日志中也未出现任何错误
希望通过重启数据库解决：
但是执行shutdown immediate后，数据库无反应，看alert日志
License high water mark = 45 Stopping Job queue slave processes, flags = 7 Tue Mar 17 16:42:09 2015 Errors in file /Oracle/apps/oracle/diag/rdbms/gjjs/gjjs/trace/gjjs_j002_28185.trc: ORA-12012: error on auto execute of job "EXFSYS"."RLM$EVTCLEANUP" ORA-01089: immediate shutdown in progress - no operations are permitted ORA-01089: immediate shutdown in progress - no operations are permitted Process ID: Session ID: 0 Serial number: 0 Tue Mar 17 16:42:09 2015 Errors in file /Oracle/apps/oracle/diag/rdbms/gjjs/gjjs/trace/gjjs_j001_17723.trc: ORA-12012: error on auto execute of job "EXFSYS"."RLM$SCHDNEGACTION" ORA-01089: immediate shutdown in progress - no operations are permitted ORA-01089: immediate shutdown in progress - no operations are permitted Process ID: Session ID: 0 Serial number: 0 Job queue slave processes stopped
CTRL+C结束，奇怪~~~
可能是日志文件出现错误，下面进行清理，并重建日志文件

难道是修改log_arch_dest_1参数需要重启数据库？？？说不通！！！
