The 64 bit version of the minimal install of Centos 6.5 is used for the Rep Attack RepAttack operating system. This is a minimal install with no X Windows software or graphical user interface. The ISO image used for the install can be found by following the links on the Centos isoredirect page.

Operating System Accounts

Oracle Express Edition

Oracle Express Edition has already been installed via it's RPM package using all default values.
An additional tablespace called REPOE_DATA has been added to hold the application data used by Rep AttackRepAttack. 

It can be downloaded from the Oracle Database Express Edition 11g Release 2 downloads page. It requires you to sign up for a (free) Oracle Account if you don't already have one.

...

Each machine has the default Oracle XE database installed as it it's default configuration. The default database installed with Oracle XE always has the ORACLE_SID of XE but to make it less confusing between the source and target databases, two TNS alias have been set up in the tnsnames.ora files of both the source and target machines.

sourcettorcl_src =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = source)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = XE)
    )
  )
targetttorcl_trg =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = target)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = XE)
    )
  )

Database User Passwords

These are the same on both the source and target databases. The passwords are set not to expire and are case sensitive in lowercase.

...

ARCHIVELOG Mode

One of the requirements for Dbvisit Replicate is that the source database be in ARCHIVELOG mode. The database on the RepAttack source machine has been placed into ARCHIVELOG mode and is using the USE_DB_RECOVERY_FILE_DEST as it's archive destination which is /u01/app/oracle/fast_recovery_area and has been sized at 10 Gb.

The database on the RepAttack target machine is not in ARCHIVELOG mode.

SwingBench

SwingBench is a free load generator and benchmark utility designed by Dominic Giles to stress test an Oracle database (10g,11g,12c).  Rep Attack .  SwingBench version 2.5.0.932 has been installed on the RepAttack source machine in /u01/app/oracle/swingbench. RepAttack uses SwingBench to generate test data and provide a transaction load for the Dbvisit Replicate.  

REPOE Schema

The Rep Attack RepAttack machines come pre-loaded with an application schema and test data generated by SwingBench that you will 'll be using to perform the Rep Attack RepAttack exercises.

The schema is called REPOE and it's based on the Order Entry (OE) example schema that comes with Oracle. It's Entity Relationship diagram is shown below.

...

oewizard -cl -create -cs //source-int/orclXE -scale 0.5 -u repoe -p repoe -ts users -tc 7 -v -dba system -dbap manager

...

For example, this is the output of the script at the start of Rep AttackRepAttack. The source schema (REPOE) has been created with the tables and loaded with the initial data, while the target schema (also called REPOE) has been created but contains no tables.

...

In the $HOME/replicate directory of the oracle user on the source machine is a script called run_swingbench.bash. This script is used on the source machine to generate DML transactions against the REPOE schema so Dbvisit Replicate has something to do.
