一、集群与资源启动顺序
启动流程步骤层次梳理
第一层:OHASD 启动:
-
cssdagent - 负责启动 CSSD 的 Agent。
-
orarootagent - 负责启动所有 root 用户下的 ohasd 资源 的Agent。
-
oraagent - 负责启动所有 oracle 用户下的 ohasd 资源的 Agent。
-
cssdmonitor - 监控 CSSD 以及节点健康(和 cssdagent 一起)。
第二层:OHASD rootagent 启动:
-
CRSD - 管理集群资源的主要后台进程。
-
CTSSD - Cluster Time Synchronization Services Daemon
-
Diskmon
-
ACFS (ASM Cluster File System)驱动
第二层:OHASD oraagent 启动:
-
MDNSD - 用来实现 DNS 查询
-
GIPCD - 用来做节点间通信
-
GPNPD - Grid Plug & Play Profile Daemon
-
EVMD - Event Monitor Daemon
-
ASM - ASM 资源
第三层:CRSD 启动:
-
orarootagent - 负责启动所有 root 用户下的 crsd 资源的 Agent。
-
oraagent - 负责启动所有 oracle 用户下的 crsd 资源的 Agent。
第四层:CRSD rootagent 启动:
-
Network resource - 监控公共网络
-
SCAN VIP(s) - Single Client Access Name Virtual IPs
-
Node VIPs - 每个节点1个
-
ACFS Registery - 挂载 ASM Cluster File System
-
GNS VIP (optional) - VIP for GNS
第四层:CRSD oraagent 启动:
-
ASM Resouce - ASM 资源
-
Diskgroup - 用来管理/监控 ASM 磁盘组
-
DB Resource - 用来管理/监控数据库和实例
-
SCAN Listener - SCAN 监听,监听在 SCAN VIP 上
-
Listener - 节点监听,监听在 Node VIP 上
-
Services - 用来管理/监控 services
-
ONS - Oracle Notification Service
-
eONS - 加强版 Oracle Notification Service
-
GSD - 为了向下兼容 9i
-
GNS (optional) - Grid Naming Service - 处理域名解析
