ORA-06553: PLS-553: character set name is not recognized, while starting Content Store
今天用PLSQL的时候通过EXCEL导入数据，发现中文均显示为?
确认是数据库字符集没有设置正常：对比正常的数据库发现NLS_CHARACTERSET为ZHS16GBK
SQL> select name,value$ from props$ where name like 'NLS%'; NAME VALUE$ ------------------------------ ---------------------------------------- NLS_LANGUAGE AMERICAN NLS_TERRITORY AMERICA NLS_CURRENCY $ NLS_ISO_CURRENCY AMERICA NLS_NUMERIC_CHARACTERS ., NLS_CHARACTERSET ZHS16GBK NLS_CALENDAR GREGORIAN NLS_DATE_FORMAT DD-MON-RR NLS_DATE_LANGUAGE AMERICAN NLS_SORT BINARY NLS_TIME_FORMAT HH.MI.SSXFF AM NAME VALUE$ ------------------------------ ---------------------------------------- NLS_TIMESTAMP_FORMAT DD-MON-RR HH.MI.SSXFF AM NLS_TIME_TZ_FORMAT HH.MI.SSXFF AM TZR NLS_TIMESTAMP_TZ_FORMAT DD-MON-RR HH.MI.SSXFF AM TZR NLS_DUAL_CURRENCY $ NLS_COMP BINARY NLS_LENGTH_SEMANTICS BYTE NLS_NCHAR_CONV_EXCP FALSE NLS_NCHAR_CHARACTERSET AL16UTF16 NLS_RDBMS_VERSION 10.2.0.4.0
网上提供的方式是直接update这个列的值，但update以后
SQL> update props$ set value$='AL32UTF8' where name='NLS_CHARACTERSET';
查看一下当前数据库的字符集信息，虽然视图显示修改成功了。但
SQL> col value for a40 SQL> Select * from NLS_DATABASE_PARAMETERS; PARAMETER VALUE ------------------------------ ---------------------------------------- NLS_LANGUAGE AMERICAN NLS_TERRITORY AMERICA NLS_CURRENCY $ NLS_ISO_CURRENCY AMERICA NLS_NUMERIC_CHARACTERS ., NLS_CHARACTERSET AL32UTF8 NLS_CALENDAR GREGORIAN NLS_DATE_FORMAT DD-MON-RR NLS_DATE_LANGUAGE AMERICAN NLS_SORT BINARY NLS_TIME_FORMAT HH.MI.SSXFF AM PARAMETER VALUE ------------------------------ ---------------------------------------- NLS_TIMESTAMP_FORMAT DD-MON-RR HH.MI.SSXFF AM NLS_TIME_TZ_FORMAT HH.MI.SSXFF AM TZR NLS_TIMESTAMP_TZ_FORMAT DD-MON-RR HH.MI.SSXFF AM TZR NLS_DUAL_CURRENCY $ NLS_COMP BINARY NLS_LENGTH_SEMANTICS BYTE NLS_NCHAR_CONV_EXCP FALSE NLS_NCHAR_CHARACTERSET AL16UTF16 NLS_RDBMS_VERSION 11.2.0.1.0
进行DDL等操作的时候会出现ORA-06553: PLS-553 的错误提示：
CM-CFG-5029 Content Manager is unable to determine whether the content store is initialized. ORA-06552: PL/SQL: Compilation unit analysis terminated ORA-06553: PLS-553: character set name is not recognized
可以判断是字符集冲突导致的，查看
ALTER DATABASE CHARACTER SET ZHS16GBK; ALTER DATABASE CHARACTER SET INTERNAL_USE ZHS16GBK;
修改的时候还遇到一个错误提示：
ERROR at line 1: ORA-12719: operation requires database is in RESTRICTED mode [oracle@021Y-SH-BKAP ~]$ oerr ora 12719 12719, 00000, "operation requires database is in RESTRICTED mode" // *Cause: This command can only be run when the database is in RESTRICTED mode // *Action: Ensure that the system is in RESTRICTED mode
解决方式：
SHUTDOWN IMMEDIATE; STARTUP MOUNT EXCLUSIVE; ALTER SYSTEM ENABLE RESTRICTED SESSION
确认修改成功后，重启数据库。注意如果是生产环境重启前也要关闭工作计划。
show parameter job_queue_processes; show parameter aq_tm_processes; alter database set job_queue_processes=0;
