在本身的虛擬機的作實驗,忽然發現使用PL/SQL Developer沒法鏈接到數據庫,報錯ORA-12514,說是監聽沒有啓動。css
先介紹虛擬機一下環境:redhat7.2+GI 12.2.0.1+Oracle 12.2.0.1,爲了測試12.2的ASM特性安裝了GI。平時監聽程序默認是開啓啓動的。可是今天不知道爲何沒有啓動。使用crsctl查看資源狀態:發現監聽的狀態確實是OFFLINE狀態數據庫
[root@rhel7 .oracle]# crsstat -------------------------------------------------------------------------------- Name Target State Server State details -------------------------------------------------------------------------------- Local Resources -------------------------------------------------------------------------------- ora.DATA.dg ONLINE ONLINE rhel7 STABLE ora.LISTENER.lsnr ONLINE OFFLINE rhel7 STABLE ora.asm ONLINE ONLINE rhel7 Started,STABLE ora.ons OFFLINE OFFLINE rhel7 STABLE -------------------------------------------------------------------------------- Cluster Resources -------------------------------------------------------------------------------- ora.cssd 1 ONLINE ONLINE rhel7 STABLE ora.diskmon 1 OFFLINE OFFLINE STABLE ora.driver.afd 1 ONLINE ONLINE rhel7 STABLE ora.evmd 1 ONLINE ONLINE rhel7 STABLE ora.ora12c.db 1 ONLINE ONLINE rhel7 Open,HOME=/u01/app/o racle/product/12.2/d b_home1,STABLE --------------------------------------------------------------------------------
嘗試手動啓動監聽,依然報錯:bash
[grid@rhel7 ~]$ srvctl start listener PRCR-1079 : Failed to start resource ora.LISTENER.lsnr CRS-5016: Process "/u01/app/grid/bin/lsnrctl" spawned by agent "ORAAGENT" for action "start" failed: details at "(:CLSN00010:)" in "/u01/app/12.2/grid/diag/crs/rhel7/crs/trace/ohasd_oraagent_grid.trc" CRS-5016: Process "/u01/app/grid/bin/lsnrctl" spawned by agent "ORAAGENT" for action "start" failed: details at "(:CLSN00010:)" in "/u01/app/12.2/grid/diag/crs/rhel7/crs/trace/ohasd_oraagent_grid.trc" CRS-2674: Start of 'ora.LISTENER.lsnr' on 'rhel7' failed
根據提示查看trc文件,看到以下報錯:oracle
LSNRCTL for Linux: Version 12.2.0.1.0 - Production on 15-NOV-2017 20:03:28 Copyright (c) 1991, 2016, Oracle. All rights reserved. Starting /u01/app/grid/bin/tnslsnr: please wait...

See the error message(s) above...
看到Insufficient privilege for operation這個字樣以爲很納悶,怎麼會權限不足呢,因而嘗試用root直接啓動監聽,依然報錯:app
[root@rhel7 .oracle]# lsnrctl start LSNRCTL for Linux: Version 12.2.0.1.0 - Production on 15-NOV-2017 20:22:30 Copyright (c) 1991, 2016, Oracle. All rights reserved.

因而各類百度,下面把百度到內容列出來,可能會對看此文的同窗有用,可是對我這種狀況沒有用:
tcp
主要是說 /var/tmp/.oracle、/tmp/.oracle 這兩個目錄的權限訪問問題。 進入 一看,個人/var/tmp/.oracle權限 沒問題,而/tmp/.oracle壓根就沒有這個文件。ide
因而直接查MOS,看有沒有相關的文檔,找到兩篇文檔:測試
Starting the Listener Fails With: TNS-12557 or TNS-12555: TNS:Permission Denied (文檔 ID 343253.1)this
Listener Fails To Start With IPC Permission Errors (TNS-12546 TNS-12555 TNS-00516 TNS-00525) (文檔 ID 434062.1)spa
對比了文檔中列出的問題,跟個人狀況也不一相,看到最後發現這樣一句話:
4. If you find that there are no adapters linked or they have errors (such as "Permission denied") then issue a "relink all"
Reference:
Doc ID 1467060.1
因而只有用這種方法來試試了,因爲crs使用的是grid home下的監聽命令因此對grid home作relink all操做。但是又出現報錯:
[grid@rhel7 bin]$ relink all The Oracle home in which you are running this relinking tool does not have proper write permissions. Please run this relink script as the same user who owns the Oracle home and ensure that the Oracle home has the permissions from the original installation. If this is a Grid Infrastructure home, please refer to the documentation for the proper steps to relink and apply oneoff patches.
意思是說權限不足,使用root執行,又報錯說不能用root執行
[root@rhel7 bin]# relink all The relink script cannot be run as root.
又查看grid home目錄權限
[root@rhel7 app]# ls -ld grid total 8 drwxr-x--- 84 root oinstall 4096 Jul 18 20:26 grid
原來owner是root,怪不得第一次執行不成功,修改owner(應該直接chmod也能夠,這裏沒有作測試),從新執行relink all
[root@rhel7 app]# chown grid grid [grid@rhel7 ~]$ relink all writing relink log to: /u01/app/grid/install/relink.log
成功後再次啓動監聽,啓動成功。

至次問題解決。
