ORA-01078: failure in processing system parameters

LRM-00109: could not open parameter file '/oracle/app/oracle/product/12.1.0.2/db_1/dbs/inittestdb1.ora'

一、在/oracle/app/oracle/product/12.1.0.2/db_1/dbs/目錄下，沒法找到inittestdb1.ora文件。

二、將/oracle/app/oracle/admin/testdb/pfile/init.ora.816201714541文件複製到

   /oracle/app/oracle/product/12.1.0.2/db_1/dbs/目錄下,並更名爲：inittestdb1.ora

$cp init.ora.816201714541 /oracle/app/oracle/product/12.1.0.2/db_1/dbs/inittestdb1.ora

三、sqlplus "/as sysdba"
