Dear fellow DBA's and Experts,
Good Day.
We presently have an existing database registered (on V2 Exadata) with global database name as BIDEV.domainname.com. It has 4 instances viz., BIDEV1 and BIDEV2 which have the same service name as the instance name.
Last week, on our new X4-2 Exadata, we tried to create a fresh database. While doing so, we entered the details as below in the installer:
Global Database Name: BIDEV
SID Prefix: BIDEV
Service Name: BIDEV.
Then upon the successful installation of the database, when we query
1. (SELECT * FROM GLOBAL_NAME), it shows BIDEV as the global database name.
2.
SQL> sho parameter service
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
service_names string BIDEV1
3. Sho parameter name gives the below details:
SQL> sho parameter name;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
cell_offloadgroup_name string
db_file_name_convert string
db_name string BIDEV
db_unique_name string BIDEV
global_names boolean FALSE
instance_name string BIDEV_1
lock_name_space string
log_file_name_convert string
processor_group_name string
service_names string BIDEV1
Curious to know why it created an instance name as BIDEV_1 instead as BIDEV1.
Had tried another attempt on our test environment with SID prefix as BIDEV1, then the instance was created with the name as BIDEV1_1.
Also, would like to know what happen if we give the Global Database Name as BIDEV.domainname.com for installing the same BIDEV database on a different server while the 1st server is still functional.
Appreciate if someone could throw some light on the above confusion. Any reference material or source to the clarify the doubt.
Warm Regards,
Vikram.
