Oracle数据库使用出现错误-状态: 失败 ORA-01034: ORACLE not available ORA-27101: shared memory realm does not exist
解决办法:
1.确认Oracle相关服务已启动:
2.修改pfile文件:
pfile根据Oracle安装的路径而定 ,本文路径:C:appAdministratoradminorclpfileinit.ora.8172019101639
3.pfile文件修改内容:
找到Network Registration,修改下面的local_listener="(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))",这个 (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521)) 内容可以从C:appAdministratorproduct11.2.0dbhome_1NETWORKADMINtnsnames.ora文件找到
4.执行以下命令:
sqlplus /nolog
conn system/manager as sysdba
startup
startup pfile=’C:appAdministratoradminorclpfileinit.ora.8172019101639’
