Two different list of databases on MySQL-cluster-7.1.22 while putting the 2 different commands (no replies)

Hi All,

I installed the MySQL-Cluster-7.1.22 versin on Windows 7.
As per the installation guide that is on MySQL website ie."installation of MySQL-Cluster" I installed the mysql.

Here my problem is :

CASE:1 :

When I tried to login using command : mysql -uroot -proot
It was logedin successfully.

I got the following trace:

mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| capv2routedb |
| eceaccore |
| ecedatabase |
| ecegeodatabase |
| mysql |
| sigdb |
| sigdb1 |
| test |
+--------------------+
9 rows in set (0.00 sec)

These number of databases we have.

CASE:2 :

When I am login with command: mysql -uroot -P500
-----------
[This command for up the ndbcluster storage engine]

We got the different set of databases:

mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| ndbinfo |
| performance_schema |
| sigdb |
+--------------------+
5 rows in set (0.00 sec)
==========================================================
I have following questions:

Question1:
why we are getting the different set of databases. I have only installed the MySQL-cluster-7.1.22.

Question2:

In CASE:1, If I tried to create a table which having a PRIMARY KEY value varchar(500), then It throws error like:

"Specified key was too long; max key length is 1000 bytes"

because we were using the UTF8 character-set encoding.

BUT in CASE:2, if I created the table which having the PRIMARY KEY value varchar(500), then It crated successfully with any error.

Here my finding is, It is also using the UTF8 chatacter-set encoding.

Why these above tow CASES behaves different ?

I am not sure the above explanation is clear, but if any one have query, please let me know...

Please share your inputs on this.


Thanks,
Upendra
