ORA-16018解决办法

gtdfe

因为11g归档日志默认路径是：DB_RECOVERY_FILE_DEST  空间大小是2G 导致日志撑满，数据库hang住了
修改归档日志报ORA-16018错误：
先创建归档日志存放目录：

orahost:root:[/oracle]#mkdir arch_log
orahost:root:[/oracle]#chown –R oracle:oinstall ./arch_log
orahost:root:[/oracle]#chmod 775 ./arch_log
orahost:root:[/oracle/arch_log]#su – oracle
然后修改路径：
SQL> alter system set log_archive_dest='/arch_log';
alter system set log_archive_dest='/arch_log'
*
ERROR at line 1:
ORA-02097: parameter cannot be modified because specified value is invalid
ORA-16018: cannot use LOG_ARCHIVE_DEST with LOG_ARCHIVE_DEST_n or
DB_RECOVERY_FILE_DEST
[oracle@bsqkpi dbs]$ oerr ora 16018
16018, 00000, "cannot use %s with LOG_ARCHIVE_DEST_n or DB_RECOVERY_FILE_DEST"
// *Cause:  One of the following events caused an incompatibility:
//          1) Parameter LOG_ARCHIVE_DEST or LOG_ARCHIVE_DUPLEX_DEST
//          was in use when a LOG_ARCHIVE_DEST_n (n = 1...31) parameter
//          was encountered while fetching initialization parameters.
//          2) An ALTER SYSTEM ARCHIVE LOG START TO command was in effect when
//          a LOG_ARCHIVE_DEST_n parameter was encountered while fetching
//          initialization parameters.
//          3) A LOG_ARCHIVE_DEST_n parameter was in use when an ALTER SYSTEM
//          command was used to define a value for either the LOG_ARCHIVE_DEST
//          or LOG_ARCHIVE_DUPLEX_DEST parameter.
//          4) Parameter DB_RECOVERY_FILE_DEST was in use when an attempt
//          was made to use an ALTER SYSTEM or ALTER SESSION command to
//          define a value for LOG_ARCHIVE_DEST or LOG_ARCHIVE_DUPLEX_DEST.
// *Action: Eliminate any incompatible parameter definitions.
提示有冲突
进入pfile把DB_recovery_FILE_DEST=……***掉
然后

File created.
SQL> shutdown immediate
