Using Read-Only Hardware

This example describes read-only hardware operations in a typical scenario.

Note: Read-only hardware functionality does not require WORM disk array hardware. You may remove write privilege from a raw device or file system file after the dbspace is altered read-only.
  1. Create an Archive
    For this example, consider an IQ database consisting of a single catalog store dbspace named db.db with three main IQ dbspaces: A, B and C.
  2. Create New Dbspaces
    You may create new dbspaces after creating the archive.
  3. Examine Archived Data
    Suppose that you need to examine the archived database as of time t0.
  4. Update the Working Archive
    If years have passed since time t0, you may upgrade the db.db0.working as long as ALTER DATABASE UPGRADE modifies no objects in the IQ main store.
  5. Create More Archives
    Create a new archive at time t1 as follows.
