单机RAC修改主机名称后,has无法启动
问题:修改主机名称后,has无法启动
hostnamectl set-hostname hxlhost
grid修改主机名后报错误
[root@hxlhost bin]# ./crsctl start has
CLSU-00100: Operating System function: opendir failed with error data: 2
CLSU-00101: Operating System error message: No such file or directory
CLSU-00103: error location: scrsearch1
CLSU-00104: additional error information: cant open scr home dir scls_scr_getval
CRS-4000: Command Start failed, or completed with errors.
解决方案
1.删除Restart(Remove Oracle Restart configuration)
[root@hxlhost bin]# /u01/grid/grid_home/perl/bin/perl -I/u01/grid/grid_home/perl/lib -I/u01/grid/grid_home/crs/install /u01/grid/grid_home/crs/install/roothas.pl -deconfig -force -verbose
Using configuration parameter file: /u01/grid/grid_home/crs/install/crsconfig_params
CRS-4639: Could not contact Oracle High Availability Services
CRS-4000: Command Stop failed, or completed with errors.

2.ReconfigureOracle Restart
[root@hxlhost bin]# /u01/grid/grid_home/perl/bin/perl -I/u01/grid/grid_home/perl/lib -I/u01/grid/grid_home/crs/install /u01/grid/grid_home/crs/install/roothas.pl
Using configuration parameter file: /u01/grid/grid_home/crs/install/crsconfig_params

3.启动cssd
[root@hxlhost bin]# ./crs_stat -t -v
Name Type R/RA F/FT Target State Host
----------------------------------------------------------------------
ora.cssd ora.cssd.type 0/5 0/5 OFFLINE OFFLINE
ora.diskmon ora....on.type 0/10 0/5 OFFLINE OFFLINE
ora.evmd ora.evm.type 0/10 0/5 ONLINE ONLINE hxlhost
ora.ons ora.ons.type 0/3 0/ OFFLINE OFFLINE
[root@hxlhost bin]#
[root@hxlhost bin]# ./crsctl start resource ora.cssd
CRS-2672: Attempting to start 'ora.cssd' on 'hxlhost'
CRS-2672: Attempting to start 'ora.diskmon' on 'hxlhost'
CRS-2676: Start of 'ora.diskmon' on 'hxlhost' succeeded
CRS-2676: Start of 'ora.cssd' on 'hxlhost' succeeded
[root@hxlhost bin]#
4.将asm服务添加到grid,grid用户下添加(grid用户下操作)
[grid@hxlhost ~]$ srvctl add asm
[grid@hxlhost ~]$
重新配置asm参数然后启动
编辑初始化参数
[grid@oragrid dbs]$ vi /tmp/init+ASM.ora
asm_diskstring='/dev/asm*'
asm_diskgroups='DATA'
asm_power_limit=1
diagnostic_dest='/u01/grid/grid_base'
instance_type='asm'
large_pool_size=12M
remote_login_passwordfile='EXCLUSIVE'
关闭asm实例,若是没有关闭的话
SQL> shutdown immediate
ORA-15100: invalid or missing diskgroup name
ASM instance shutdown
创建spfile
SQL> connect / as sysasm
Connected to an idle instance.
SQL> create spfile from pfile='/tmp/init+ASM.ora';
File created.
然后启动
SQL> startup
ASM instance started
Total System Global Area 1135747072 bytes
Fixed Size 2260728 bytes
Variable Size 1108320520 bytes
ASM Cache 25165824 bytes
ASM diskgroups mounted
检查asm资源情况
[grid@hxlhost ~]$ crs_stat -t -v
Name Type R/RA F/FT Target State Host
----------------------------------------------------------------------
ora.DATA.dg ora....up.type 0/5 0/ ONLINE ONLINE hxlhost
ora.asm ora.asm.type 0/5 0/ ONLINE ONLINE hxlhost
ora.cssd ora.cssd.type 0/5 0/5 ONLINE ONLINE hxlhost
ora.diskmon ora....on.type 0/10 0/5 OFFLINE OFFLINE
ora.evmd ora.evm.type 0/10 0/5 ONLINE ONLINE hxlhost
ora.ons ora.ons.type 0/3 0/ OFFLINE OFFLINE
5.添加数据库(oracle用户下操作)
[oracle@hxlhost ~]$ srvctl add database -d restart -o /u01/oracle/app/product/11.2.0/db_1
参数说明
-d db_unique_name
-o oracle_home
启动数据库
[oracle@hxlhost ~]$ srvctl start database -d restart
root用户下查看数据库状态
[root@hxlhost bin]# ./crs_stat -t -v
Name Type R/RA F/FT Target State Host
----------------------------------------------------------------------
ora.DATA.dg ora....up.type 0/5 0/ ONLINE ONLINE hxlhost
ora.asm ora.asm.type 0/5 0/ ONLINE ONLINE hxlhost
ora.cssd ora.cssd.type 0/5 0/5 ONLINE ONLINE hxlhost
ora.diskmon ora....on.type 0/10 0/5 OFFLINE OFFLINE
ora.evmd ora.evm.type 0/10 0/5 ONLINE ONLINE hxlhost
ora.ons ora.ons.type 0/3 0/ OFFLINE OFFLINE
ora.restart.db ora....se.type 0/2 0/1 ONLINE ONLINE hxlhost
[root@hxlhost bin]#
6.修改监听文件(grid用户下操作)
[grid@hxlhost admin]$ cd /u01/grid/grid_home/network/admin
[grid@hxlhost admin]$ more listener.ora
# listener.ora Network Configuration File: /u01/grid/grid_home/network/admin/listener.ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = hxlhost)(PORT = 1521))
)
)
ADR_BASE_LISTENER = /u01/grid/grid_base
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER=ON # line added by Agent
[grid@hxlhost admin]$
6.启动监听器(该监听器即监听asm实例和数据库实例)
[grid@hxlhost ~]$ srvctl add listener
[grid@hxlhost ~]$ srvctl start listener
7.查看资源情况
[grid@hxlhost admin]$ crs_stat -t -v
Name Type R/RA F/FT Target State Host
----------------------------------------------------------------------
ora.DATA.dg ora....up.type 0/5 0/ ONLINE ONLINE hxlhost
ora....ER.lsnr ora....er.type 0/5 0/ ONLINE ONLINE hxlhost
ora.asm ora.asm.type 0/5 0/ ONLINE ONLINE hxlhost
ora.cssd ora.cssd.type 0/5 0/5 ONLINE ONLINE hxlhost
ora.diskmon ora....on.type 0/10 0/5 OFFLINE OFFLINE
ora.evmd ora.evm.type 0/10 0/5 ONLINE ONLINE hxlhost
ora.ons ora.ons.type 0/3 0/ OFFLINE OFFLINE
ora.restart.db ora....se.type 0/2 0/1 ONLINE ONLINE hxlhost
-- The End --
