ORA-29701: unable to connect to Cluster Synchronization Service and ORA-01078

Hi,

After Oracle 18c Automatic Storage management software is completed, i tried to start ASM instance but i got ” ORA-29701: unable to connect to Cluster Synchronization Service ” error.

 

ORA-29701: unable to connect to Cluster Synchronization Service

[oracle@MehmetSalih ~]$ sqlplus / as sysasm

SQL*Plus: Release 18.0.0.0.0 - Production on Tue Feb 19 12:58:59 2019
Version 18.3.0.0.0

Copyright (c) 1982, 2018, Oracle. All rights reserved.

Connected to an idle instance.

SQL> startup
ORA-01078: failure in processing system parameters
ORA-29701: unable to connect to Cluster Synchronization Service
SQL> exit
Disconnected
[oracle@MehmetSalih ~]$

 

To solve this problem, you need to enable has ( high availability services ) and start ora.cssd resource like below. If you execute following script then you can startup asm again. It will be started.

 

 

 

 

[oracle@MehmetSalih ~]$ crsctl enable has
CRS-4622: Oracle High Availability Services autostart is enabled.
[oracle@MehmetSalih ~]$
[oracle@MehmetSalih ~]$


[oracle@MehmetSalih ~]$ crsctl start res ora.cssd -init
CRS-2672: Attempting to start 'ora.cssd' on 'mehmetsalih'
CRS-2672: Attempting to start 'ora.diskmon' on 'mehmetsalih'
CRS-2676: Start of 'ora.diskmon' on 'mehmetsalih' succeeded
CRS-2676: Start of 'ora.cssd' on 'mehmetsalih' succeeded
[oracle@MehmetSalih ~]$

 

problem has been solved.
