1. +++++++++++++++++++++++++++++++++++++++
++ + Create a TimesTen in memory database +++
+++++++++++++++++++++++++++++++++++++++
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]

2. 2. Specify New data Source definition
===================================
edit sys.odbc.ini to add source definition and save
Driver - location of the TimesTen direct linked ODBC driver
DataSource - location and name of the database files
LogDir - directory for the transaction logs
PermSize - Permanent partition of the database size in MB
TempSize -Temporary partition of the database size in MB
DatabaseCharacterSet - Character Set of the database
3. Verify that database daemon is running
================================

3. 4. ttisql to connect database and create the database store
============================================

4. So mono_ttdb database has been created and loaded into memory.
Check the TimesTen in memory Database status
+++++++++++++++++++++++++++++++++++++
[oracle@cloud bin]$ ./ttstatus
TimesTen status report as of Tue Nov 19 05:09:33 2013

End of report
[oracle@cloud bin]$ ./ttisql mono_ttdb

Type ? or "help" for help, type "exit" to quit ttIsql.

5. connect "DSN=mono_ttdb";
Connection successful:
DSN=MONO_TTDB;UID=oracle;DataStore=/u01/app/ttdata/datastores/mono_ttdb;DatabaseCh
aracterSet=AL32UTF8;ConnectionCharacterSet=US7ASCII;DRIVER=/home/oracle/TimesTen/t
t1122/lib/libtten.so;LogDir=/u01/app/ttdata/logs;PermSize=40;TempSize=32;TypeMode=0;
(Default setting AutoCommit=1)
Current size of the permanent and temporary data stores
+++++++++++++++++++++++++++++++++++++++++
Command> dssize
PERM_ALLOCATED_SIZE:
40960
PERM_IN_USE_SIZE:
9389
PERM_IN_USE_HIGH_WATER: 9389
TEMP_ALLOCATED_SIZE:
32768
TEMP_IN_USE_SIZE:
9442
TEMP_IN_USE_HIGH_WATER: 9505
Create a user and then object under that user
=================================

6. Now check the DataStore and LogDir
============================
[oracle@cloud datastores]$ ls -ltra

Note: TimesTen maintain two complete images on the disk and known as checkpoints
Transaction logs for recovery
