Initial Catalog Creation

The catalog itself is placed on the HOST filesystem. If it doesn't exist, it's automatically created.

We will start by cataloging the CYBIS/R1 system by issuing the following command: 

 cdc.io c.catalog -d demodatabase.sqlite3 -c "E:\Emulation\TH.CybisRelease1\disks" TH.CybisRelease1

where:

-d demodatabase.sqlite3 is the name of the catalog database

-c “E:\Emulation\TH.CybisRelease1\disks” is the path-type cluster of disks to be scanned/cataloged

TH.CybisRelease1 is the character string (your choice) which names this inventory/collection.

For each PLATO file that is found, an entry is created in the database.

The first time a cluster is cataloged, the procedure takes a bit of time and depends (mostly) on CPU speed because each entry is being cryptographically hashed, defining a unique signature for the file.

Get some coffee…

When the process ends - you'll see:

Module 'cdc_io' Completed

Now do the same thing for the CYBIS/R2 instance. 

 cdc.io c.catalog -d demodatabase.sqlite3 -c "E:\Emulation\CybisRelease2.Prod\disks" CybisRelease2

Get some more coffee…

Once you see:

Module 'cdc_io' Completed

Check Your Work

Check your work by issuing the following command 

 cdc.io cat.list -d demodatabase.sqlite3

The response should be:

Cluster Name 0 CybisRelease2 1 TH.CybisRelease1

Test Compare

Now all of your hard work pays off! If you want to compare the two instances, issue the following command: 

cdc.io cat.compare -d demodatabase.sqlite3 "TH.CybisRelease1" "CybisRelease2"

The response should be:

There are 30 differences between TH.CybisRelease1 and CybisRelease2.

Success!

You have now:

  • cataloged two different instances (took some time)
  • listed the names of the instances from the database (took no time)
  • compared the FULL contents of two separate instances (in under a second)!
