informatica的服务起不来，报错代码CCM_10322，DOM_10022

背景：因为要备份服务器，我们将INFA的测试环境服务器停掉以后开始备份，等备份完成起infa服务时发现服务起不来，当时就判断

检查：我去查看日志exceptions.log，发现以下错误

错误：以下为部分错误信息

2019-01-17 10:01:44,874 ERROR [Monitor Guaranteed Message Logger Thread] [CCM_10322] While logging messages to the Log Service, the following error occurred: [[DOM_10022] The master gateway node for the domain is not available.

 问题原因：

由于在停止应用服务器的时候忽略了资料库服务，没有正常停止资料库，导致资料库没有正常自启动（数据库设置了自启动）（在我上篇文章中特别强调了启停的注意事项）

查看数据库时发现数据库异常：

ERROR:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Process ID: 0
Session ID: 0 Serial number: 0

解决方案：

用Oracle用户登陆服务器，查看监听，并启动监听，登陆Oracle数据，启动数据库，验证，然后启动好数据库后启动infa应用服务

查看监听：lsnrctl status，若没有启动

启动监听：lsnrctl start

无用户登陆数据库：sqlplus  /nolog

管理员账户登陆：conn / as  sysdba

启动数据库：startup

检查：select * from dba_users;
