错误描述
ORA-00843: Parameter not taking MEMORY_MAX_TARGET into account ORA-00849: SGA_TARGET 4194304 cannot be set to more than MEMORY_MAX_TARGET 0.
错误原因
memory_max_target memory_target 两个参数关闭时，不能同时显式的指定为0，同时指定为0，启动时将会发生上面错误，导致ASM启动失败，进而导致CRS启动失败 SQL> alter system set sga_target=700M scope=spfile; System altered. SQL> alter system set sga_max_size=800M scope=spfile; System altered. SQL> alter system set pga_aggregate_target=200M scope=spfile; SQL> alter system set memory_target=0 scope=spfile sid='*'; System altered. SQL> alter system set memory_max_target=0 scope=spfile sid='*'; System altered. SQL> alter system reset memory_max_target scope=spfile sid='*'; System altered.
当发生ASM由于上面报错无法启动时解决
/* 独占模式启动crs /* 11.2.0.1 # crsctl start crs -excl /* 11.2.0.2以后 # crsctl start crs -excl -nocrs /* 手工编写asm pfile，指定pfile启动asm实例 $ sqlplus / as sysasm SQL > startup pfile='/tmp/asm.pfile'; /* 手工修改pfile之后，创建spfile SQL> create spfile='+OCRDG' from pfile=''; /* 启动测试 $ sqlplus / as sysasm SQL> shutdown immediate; SQL> startup; /* 关闭ASM实例，启动集群 # crsctl stop crs -f # crsctl start crs
