1。查询注册表,获取oracle安装根目录
HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\ORACLE_HOME REG_SZ E:\ORACLE\ORA92
得知oracle服务名文件所在地:根目录\network\ADMIN\tnsnames.ora
2。解析该文件,该文件结构如
# ------------------------------------------------
PORTAL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 134.104.52.6)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = portal)
)
)
一行一行获取再解析
跳过以#打头的注释行
过滤掉空格后,首字符在A~z之间的行就包含了Oracle服务名
截取该行第一个“=”号左边的字符串,trim处理后就是Oracle服务名了
