The Autokey operations vary somewhat between the dances, but generically the protocol performs the following functions in the course of facilitating secure authentication: Detection of packet modifications via keyed message digests: Functionally, this process is the same as with private key cryptography in NTPv3 The difference is that Autokey is based on public key cryptography and is available only in NTPv4 Source identity verification via digital signatures: This feature is unique to the Autokey protocol and is not available in NPTv3 Cookie encryption: In the context of NTP, cookies are 32-bit values that are used as one of the four components from which autokey values are computed The other autokey components include the source and destination IP addresses and the key ID..

You can use Oracle s Flashback Transaction Backout feature to roll back or undo even committed statements. You can roll back a transaction and its dependent transactions as well, without having to take the database offline. The database uses the undo data to create what are called compensation transactions to return the data to its before-change state. If a set of related transactions involve complex insert, update, and delete operations, the Flashback Transaction Backout feature lets you undo the entire set of changes with literally a single click (using the Database Control). Use the TRANSACTION_BACKOUT procedure from the DBMS_FLASHBACK package to perform a transaction backout. Here s the structure of the procedure: PROCEDURE TRANSACTION_BACKOUT Argument Name -----------------------------NUMTXNS NAMES OPTIONS TIMEHINT Type ----------------------NUMBER TXNAME_ARRAY BINARY_INTEGER TIMESTAMP In/Out Default ------ -------IN IN IN DEFAULT IN

Note that the ASH is really a rolling buffer in the SGA; it is an in-memory active session history. Thus, in a busy database, older information is frequently overwritten, since ASH collects data every second from the V$SESSION view.

The transaction backout feature relies primarily on the undo data saved in the undo tablespace. However, the database also needs the redo generated by the undo blocks. Thus, you need both the undo segments and the archived redo logs to perform a Flashback Transaction Backout operation.

The DBA_HIST_ACTIVE_SESSION_HISTORY data dictionary view provides historical information about recent active session history. In other words, this view is nothing but a collection of snapshots from the V$ACTIVE_SESSION_HISTORY view, which itself is a sample of active session data. There are two ways in which the DBA_HIST_ACTIVE_SESSION_HISTORY view is populated: During the course of the regular (by default, hourly) snapshots performed by the AWR, the MMON background process flushes the ASH data to the AWR. Oracle may also need to transfer data to the DBA_HIST_ACTIVE_SESSION_HISTORY view in between the regular snapshots if the memory buffer is full and the database can t write new session activity data to it. In this case, the new MMNL background process will perform the flushing of data from the memory buffer to the data dictionary view.

Before you can use the Flashback Transaction Backout feature, you must enable supplemental logging in the database, as shown here:

You can use the ashrpt.sql script, located in the $ORACLE_HOME/rdbms/admin directory, to get an ASH report. The use of the script is similar to the AWR script awrrpt.sql described earlier in this chapter. The script generates information about the SQL that ran during the time you specify, and it includes blocking and wait details. Here s how you run the ashrpt.sql script to get an ASH report: $ $ORACLE_HOME/rdbms/admin/ashrpt.sql You are prompted for the time frame for collecting ASH information, whether you d like an HTML or text report, and the name of the report. Listing 18-9 shows a portion of an ASH report. Listing 18-9.
