GI - Grid Infrastructure Maintenance for Restart Server
1. How to Stop and Start Database?
2. How to Stop and Start ASM Instance?
3. How to Stop and Start HAS?
Database:
==========
SQL> shut immediate
SQL> startup;
SQL> startup force;
$srvctl status database -d TESTDB
$srvctl config database -d TESTDB
$srvctl stop database -d TESTDB
$srvctl start database -d TESTDB
ASM:
====
SQL> shut immediate
SQL> startup;
$srvctl status asm
$srvctl config asm
$srvctl stop asm
$srvctl stop asm -f
$srvctl start asm
ASMCMD> shutdown ---immediate/--abort
ASMCMD> startup
HAS/OHASD:
==========
$crsctl check has
$crsctl stop has
$crsctl stop has -f
$crsctl start has
$crsctl stat res -t -init
#systemctl status ohasd
#systemctl stop ohasd
#systemctl start ohasd
