still five minutes of problems. In 9i, flashback query based on time is very easy to have a large error, but fortunately, 10g has improved this. in fact, the main reason is that it takes 5 minutes for the 9i scn to synchronize with the time. That is to say, if the newly inserted data is less than 5 minutes, flashback query will be made based on the time. No data can be found.

In Oracle's latest version of 10g R2, the most timely technology should be transparent data encryption technology (transparent data encryption,tde).
TDE is used to encrypt data, usually the application logic executed by SQL does not need to be changed to function properly. In other words, the application can use the same syntax to insert data into the application table, and the Oracle database will automat

INITTRANS: the initial pre-allocated size. The default value is 2 for indexes and tables. This value is added to a frequently modified table, and the PCTFREE value needs to be increased accordingly.
MAXTRANS: maximum value that can be extended. The default value is 255, that is, the maximum number of concurrent transactions in this block. Oracle 10g. this parameter is no longer used.

Appendix II:Oracle does not allow direct changes to the owner of the table, using Export/import to achieve this.First set up Import9.par,Then, when used, the commands are as follows: Imp Parfile=/filepath/import9.parExamples of Import9.par are as follows:

Export of Oracle 10g Data Pump Partition Table
In Oracle 10 Gb, Data Pump supports local export/import of Partition Table partitions, but NET_LINK does not support partition tables. The following are some export experiments.
Local export:
C: \ Users \ xionglang> expdp test/test dumpfile = test. dmp logfile = test. log directory = dir_dump tables = t: p1
Export: R
Historically, Oracle's import and export capabilities have used disk files as storage intermediaries for unloading and reloading databases. The way to "swap files" for larger databases is a big problem. Because a large file will exceed the operating system's limit on file size, the export cannot be implemented.
Some innovative data administrators use file compression, such as the compression feature in Unix, to obtain the maximum size of a swap file. The import and export features in later vers
