SYMPTOMS

Case 1 PGA_AGGREATE_LIMIT lowering

Starting with 12.2, if pga_aggregate_limit parameter is set to a value smaller than 2G, the instance cannot be started due to below error:

SQL> startup
ORA-01078: failure in processing system parameters
ORA-00093: pga_aggregate_limit must be between 2048M and 100000G

Case 2 RAC Instance startup failure

RAC instance startup fails with error ORA-00093 ORA-01078.

Example

ORA-00093: pga_aggregate_limit must be between 5500M and 100000G
ORA-01078: failure in processing system parameters

SOLUTION

Solution for Case 1

The workaround is to manually set pga_aggregate_limit larger than 2G.

SQL> alter system set pga_aggregate_limit = 2G;

Solution for Case 2

Check and take note of current database configuration by 'srvctl config database -db '.

Example

srvctl config database -db orcl
Database unique name: orcl
Database name: orcl
Oracle home: /u01/app/oracle/product/21.3.0
Oracle user: oracle
Spfile: +DATA/ORCL/PARAMETERFILE/spfile.280.1083267531
Password file: +DATA/ORCL/PASSWORD/pwdorcl.264.1083264595
Domain:
Start options: open
Stop options: immediate
Database role: PRIMARY
Management policy: AUTOMATIC
Server pools:
Disk Groups: DATA
...

Try login to another instance.

If login is successful, descrease PROCESSES or increase PGA_AGGREGATE_LIMIT value for the failed instance.
   
Example: Assuming the failed instance name is 'orcl1'   

alter system set pga_aggregate_limit=5800m scope=spfile sid='orcl1' --加不加这个都可以

Restart the failed instance.

   
If you cannot login to other RAC instance(s), then perform the following:

1. Open the instance alert log and move to the last successful startup time,
extract 'System parameters with non-default values' to a text init file.
   
This should contain a lower PROCESSES value.
   
Modify or add the following to file:

.thread
.instance_number
.undo_tablespace
.processes
.pga_aggregate_limit
*.cluster_database=true
*.cluster_database_instances=  
   

Note: cluster_database_instances is desupported in Oracle Database 21c.--19C R20 also

Example with partial parameters

orcl1.instance_number=1
orcl2.instance_number=2
orcl1.thread=1
orcl2.thread=2
*.cluster_database=true
*.cluster_database_instances=2    <--- For versions prior to 21c
orcl1.undo_tablespace='UNDOTBS1'
orcl2.undo_tablespace='UNDOTBS2'

2. Startup the instance with the text init file

3. Create spfile '+' from pfile

4. Shutdown instance

5. From 'srvctl config database -db '' you will find a changed spfile name.

Example  

srvctl config database -db orcl
Database unique name: orcl
Database name: orcl
Oracle home: /u01/app/oracle/product/21.3.0
Oracle user: oracle
Spfile: +DATA/ORCL/PARAMETERFILE/spfile.297.1100014747
...

6. Run srvctl start database -db
