PHP oci_connect()TNS:无法解析连接标识符(ORA-12154)

Question

我在Ubuntu服务器上测试一些PHP代码,并通过"tnsping"命令检查oracle数据库连接

Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.3.14)(PORT = 1521)) (CONNECT_DATA = (SERVICE_NAME = ORCL) (SID = ORCL)))
OK (10 msec)

但是,PHP中的oci_connect函数显示类似于的警告

警告:oci_connect():ORA-12154:TNS:无法解析第6行中/usr/local/ipm5/wui/manager/123.bih中指定的连接标识符2

当然,OCI8启用(通过检查的phpinfo)和一些环境(PATH,ORACLE_BASE,ORACLE_HOME,ORACLE_SID,TNS_ADMIN,LD_LIBRARY_PATH)变量被设置成/etc/bash.bashrc

有人推荐?? 问题是什么

Answer 1

而不是ORCL,您可能希望将整个字符串放在oci_connect中

(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.3.14)(PORT = 1521)) (CONNECT_DATA = (SERVICE_NAME = ORCL) (SID = ORCL)))

PHP代码:

oci_connect($username, $password, '(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.3.14)(PORT = 1521)) (CONNECT_DATA = (SERVICE_NAME = ORCL) (SID = ORCL)))');

检查phpinfo()输出"Environment"部分,如果你没有ORACLE_HOME,TNS_ADMIN,你需要让那些可用的PHP运行环境,对于用php_module编译的apache

export ORACLE_HOME=/path/to/oracle_home
export TNS_ADMIN=/path/to/tns_admin
apachectl start

对于php-cgi或php-fpm

export ORACLE_HOME=/path/to/oracle_home
export TNS_ADMIN=/path/to/tns_admin
/script/to/start/fpm
