Oracle在修改参数后启动时报下列错误

SYS@PROD >startup
ORA-00119: invalid specification for system parameter DISPATCHERS
ORA-00111: invalid attribute DISPPATCHERS

解决方法

1.创建pfile

SYS@PROD >create pfile from spfile;

File created.

2.修改pfile

[oracle@edbjr2p1 dbs]$ vim initPROD.ora 

*.dispatchers='(PROT=TCP)(DISPATCHERS=2)'

3.从pfile启动

SYS@PROD >startup pfile='/u01/app/oracle/product/11.2.0/db_1/dbs/initPROD.ora';
ORACLE instance started.
