6. Step on the hole guide （ Problems encountered ）

It's on paper , We must know that we must do it .
I thought I was Windows Installing a database on is the easiest thing to do , But it took some trouble .

6.1. [DBT-50000] Unable to check available memory

During installation , Yes DBT-50000 The mistake was a bit unexpected , So an investigation was carried out .
In general , The solution is as follows ：

1. because Bug Influence , Cause problems , You can use the following command to avoid DBCA Check during operation .
   Solution example ：
   $ dbca -J-Doracle.assistants.dbca.validate.ConfigurationParams=false

2. Due to the influence of the default memory setting , You can use advanced configuration to set the memory to a smaller size .

3. Restart the computer

4. Use the administrator account to run dbca

The reason for my problem is that I have neglected “ Need to be To run with an administrator account ” this .
（ It's really important to look at online documents ）
