By default when you receive your appliance from Cisco and boot it up, the appliance is running in single mode In single mode, the appliance acts as a stand-alone firewall To use contexts (assuming you have the appropriate licensing on the appliance), you have to switch to multiple mode As you will see later in the Switching to Multiple Mode section, you have the option of importing the appliance stand-alone (single mode) configuration into a context

s 19 and 20) The response time for a query-evaluation plan (that is, the clock time required to execute the plan), assuming no other activity is going on on the computer, would account for all these costs, and could be used as a good measure of the cost of the plan In large database systems, however, disk accesses (which we measure as the number of transfers of blocks from disk) are usually the most important cost, since disk accesses are slow compared to in-memory operations Moreover, CPU speeds have been improving much faster than have disk speeds Thus, it is likely that the time spent in disk activity will continue to dominate the total time to execute a query Finally, estimating the CPU time is relatively hard, compared to estimating the disk-access cost Therefore, most people consider the disk-access cost a reasonable measure of the cost of a query-evaluation plan We use the number of block transfers from disk as a measure of the actual cost To simplify our computation of disk-access cost, we assume that all transfers of blocks have the same cost This assumption ignores the variance arising from rotational latency (waiting for the desired data to spin under the read write head) and seek time (the time that it takes to move the head over the desired track or cylinder) To get more precise numbers, we need to distinguish between sequential I/O, where the blocks read are contiguous on disk, and random I/O, where the blocks are noncontiguous, and an extra seek cost must be paid for each disk I/O operation We also need to distinguish between reads and writes of blocks, since it takes more time to write a block to disk than to read a block from disk A more accurate measure would therefore estimate 1 The number of seek operations performed 2 The number of blocks read 3 The number of blocks written and then add up these numbers after multiplying them by the average seek time, average transfer time for reading a block, and average transfer time for writing a block, respectively Real-life query optimizers also take CPU costs into account when computing the cost of an operation For simplicity we ignore these details, and leave it to you to work out more precise cost estimates for various operations The cost estimates we give ignore the cost of writing the nal result of an operation back to disk These are taken into account separately where required The costs of all the algorithms that we consider depend on the size of the buffer in main memory In the best case, all data can be read into the buffers, and the disk does not need to be accessed again In the worst case, we assume that the buffer can hold only a few blocks of data approximately one block per relation When presenting cost estimates, we generally assume the worst case.

When you boot up in multiple mode from the CLI, you are taken into the system area The system area is used to configure the physical properties of the interfaces, create VLANs for trunking, create resource classes to restrict the context system resource usage, and initially to create the contexts themselves You can also password-protect the system area to restrict access to it, as well as other administrative functions In other words, the system area is where you configure system resources that affect the security appliance as a whole; however, the individual security policies are configured within the contexts themselves The system area doesn t count as a context itself and thus doesn t affect your licensing

In query processing, the le scan is the lowest-level operator to access data File scans are search algorithms that locate and retrieve records that ful ll a selection condition
