TimesTen in memory database Creation
Download as DOCX, PDF0 likes550 views
The document outlines the steps to create a TimesTen in-memory database, starting with defining a data source name (DSN) in the sys.odbc.ini file. It details the specifications needed for data source definition, verifying the database daemon status, and using ttisql to connect and create the database. Additionally, it includes commands to check the status and logs of the database after creation.

Assumption: TimesTen database software has been installed
Oracle user has been used for TimesTen installed. So OS user Oracle is the administrator user for
creating TimesTen database.
1. Define a Data Source Name (DSN)
==============================
DSN defines the configuration of the database and must be defined before creating Database.
Modify the sys.odbc.ini [Add DSN anywhere in the ODBC DATA Sources section]](https://image.slidesharecdn.com/createatimestendatabase-131119064252-phpapp02/85/TimesTen-in-memory-database-Creation-1-320.jpg)
