If you root then execute su – oracle
Then > . oraenv
Write down: +ASM
Before start with the Oracle Restart process you must stop the listener:

Remove the existing configuration calling Oracle Restart as root (with ORACLE_HOME set to the grid home), set GRID environment:

Change Hostname
It’s the moment to change the hostname of your Server
/etc/sysconfig/network
Edit this file and set the new name
vim /etc/sysconfig/network NETWORKING=yes HOSTNAME=DB-TEST-NEW
or use nmtui tool
/etc/hosts
Update /etc/hosts as appropriate
vim /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.50.4 DB-TEST-NEW DB-TEST-NEW.local.lan
ifcfg-ethX
Change the IP address. Copy first file to .bak
[[email protected] ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE="eth0" HWADDR="00:1F:4C:02:B3:03" ONBOOT="yes" IPADDR=192.168.100.10 NETMASK=255.255.255.0 GATEWAY=192.168.100.1
listener.ora
Change the hostname in the listener configuration file. Copy file first to .bak
cat $ORACLE_HOME/network/admin/listener.ora
# listener.ora Network Configuration File: /u01/app/19.3.0.0/grid/network/admin/listener.ora
# Generated by Oracle configuration tools.

)
ADR_BASE_LISTENER = /u01/app/grid

Reboot to pickup the changes
Recreate the Configuration
After change the HOSTNAME and Restart the configuration is the moment to re-configure your Grid and Oracle installations.
GRID
Call Oracle Restart as root (with ORACLE_HOME set to the grid home) to configure your GRID installation, set GRID environment:
[[email protected] ~]# export ORACLE_HOME= from upper [[email protected] ~]# export ORACLE_SID=+ASM
[[email protected] ~]# $ORACLE_HOME/perl/bin/perl -I $ORACLE_HOME/perl/lib -I $ORACLE_HOME/crs/install $ORACLE_HOME/crs/install/roothas.pl 2019-05-17 22:48:56: Checking for super user privileges 2019-05-17 22:48:56: User has super user privileges 2019-05-17 22:48:56: Parsing the host name Using configuration parameter file: /u01/app/19.3.0.0/grid/crs/install/crsconfig_params LOCAL ADD MODE Creating OCR keys for user 'oracle', privgrp 'oinstall'..

Listener,ASM,DB,Services
Exit from root user and log-on as oracle or su – oracle (with ORACLE_HOME set to the grid home) add the listener, ASM, database and services into the Oracle Restart configuration.
[[email protected] ~]$ . oraenv +ASM
LISTENER
Add the listener and start it
[[email protected] ~]$ srvctl add listener [[email protected] ~]$ srvctl start listener
ASM diskgroups
The ASM diskgroups (+DATA & +FRA) are not automatically added back to the Oracle Restart configuration add the candidate disks and start ASM:
[[email protected] ~]$ srvctl add asm -d '/dev/sd[a-h]1' [[email protected] ~]$ srvctl start asm
As you can see no diskgroups are added
[[email protected] ~]$ asmcmd lsdg
You must add it manually:
[[email protected] ~]$ sqlplus /nolog SQL> conn / as sysasm SQL> alter diskgroup data mount; SQL> alter diskgroup fra mount; SQL> exit
– If this doeasn’t work, run from GUI asmca and find candidate
/dev/oracleasm/disks/* and mount
If you don’t see disk groups:
[[email protected] ~]$ oracleasm deletedisk DATA1
and run from GUI asmca and find candidate
/dev/oracleasm/disks/* and mount
As shown by the output of srvctl status below, the diskgroup +DATA & +FRA is running on DB-TEST-NEW
[[email protected] ~]$ srvctl status diskgroup -g data Disk Group data is running on DB-DES [[email protected] ~]$ srvctl status diskgroup -g fra Disk Group fra is running on DB-DES

Database
Add the database to Oracle Restart, and configure:
[[email protected] ~]$ srvctl add database -d DB19C -o $ORACLE_HOME -n DB19C -p +DATA/DB-DES/spfileDB19C.ora -a DATA,FRA
[[email protected] ~]$ srvctl config database -d DB19C Database unique name: DB19C Database name: DB19C Oracle home: /u01/app/19.3.0.0/grid Oracle user: oracle Spfile: +DATA/DB-DES/spfileDB19C.ora Domain: Start options: open Stop options: immediate Database role: PRIMARY Management policy: AUTOMATIC Disk Groups: DATA,FRA Services:
Finally start your Database:
[[email protected] ~]$ srvctl start database -d DB19C
