數據庫 實例 監聽 自動重啟
自動重啟,需要grid的支持
自動管理資源
[oracle@edsir1p8-+ASM ~]$ crs_stat -t Name Type Target State Host ------------------------------------------------------------ ora.DATA.dg ora....up.type ONLINE ONLINE edsir1p8 ora.asm ora.asm.type ONLINE ONLINE edsir1p8 ora.cssd ora.cssd.type ONLINE ONLINE edsir1p8 ora.diskmon ora....on.type ONLINE ONLINE edsir1p8
通常2種方式自動啟動數據庫
1.
[oracle@edsir1p8-+ASM ~]$ tail -3 /etc/oratab PROD4:/u01/app/oracle/product/11.2.0/db_1:N EMREP:/u01/app/oracle/product/11.2.0/db_1:N +ASM:/u01/app/oracle/product/11.2.0/grid:N ---這種方式通常不好用
2.crs_stat
這是個資源表,讓數據庫和監聽註冊到這個表裏
[oracle@edsir1p8-+ASM ~]$ srvctl add database -d PROD4 -o /u01/app/oracle/product/11.2.0/db_1 [oracle@edsir1p8-+ASM ~]$ srvctl config database --查看哪些數據庫已經註冊
關監聽,註冊
[oracle@edsir1p8-+ASM ~]$ srvctl add listener -l listener -p 1521 -o /u01/app/or acle/product/11.2.0/db_1PRCN-2061 : Failed to add listener ora.LISTENER.lsnr PRCN-2065 : Port(s) 1521 are not available on the nodes given PRCN-2035 : Port 1521 is not available on node(s) or virtual host(s): edsir1p8.us. oracle.com
--關監聽
[oracle@edsir1p8-+ASM ~]$ lsnrctl stop [oracle@edsir1p8-+ASM ~]$ srvctl add listener -l listener -p 1521 -o /u01/app/oracle/pr oduct/11.2.0/db_1 [oracle@edsir1p8-+ASM ~]$ srvctl config listener --查看監聽是否註冊成功
[oracle@edsir1p8-+ASM ~]$ crs_stat -t Name Type Target State Host ------------------------------------------------------------ ora.DATA.dg ora....up.type ONLINE ONLINE edsir1p8 ora....ER.lsnr ora....er.type OFFLINE OFFLINE ora.asm ora.asm.type ONLINE ONLINE edsir1p8 ora.cssd ora.cssd.type ONLINE ONLINE edsir1p8 ora.diskmon ora....on.type ONLINE ONLINE edsir1p8 ora.prod4.db ora....se.type OFFLINE OFFLINE
