Before Oracle Database 10g, executing a DROP TABLE command would result in the immediate removal of the table and all its dependent objects, and all of the related space in that table segment would be released back to the database. As of Oracle Database 10g, however, the table and dependent objects aren t immediately removed. They are renamed, but they temporarily stay in the same location, and Oracle will retain them for as long as possible, based on space pressure. As noted earlier, these dropped objects are listed in the Recycle Bin, which is simply a logical container (a data dictionary table that maintains information about dropped tables, such as their new and original names). You can query it as you would a normal table to view its contents with a simple SELECT * FROM DBA_RECYCLEBIN command. As long as a table is still listed in the Recycle Bin, it can be restored at any time using the Flashback Drop feature. java qr code generator Java : Simple QR Code Generator Example - Now you Could have ...

Oct 25, 2018 · A QR Code is a 2-dimensional bar code. They're generally used to encode a URL so someone can just scan the code and visit a site. 1. Patrick Th. Eugster, Rachid Guerraoui, and Christian Heide Damm, On Objects and Events (proceedings of the Conference on Object-Oriented Programming, Systems, Languages, and Applications (OOPSLA), Tampa Bay, FL, October 2001). As of Oracle Database 10g Release 2, you can use the RECYCLEBIN initialization parameter to turn the Flashback Drop capability off. By default, the parameter is set to ON, which means that all dropped tables go into the Recycle Bin and you can recover them using the Flashback Drop feature. By setting the parameter s value to OFF, you turn the Flashback Drop feature off, and tables won t go into the Recycle Bin upon being dropped. qr code java program How to Make QR Codes with JS - YouTube

A query on the DBA_FREE_SPACE view will tell you that the space previously occupied by these dropped objects is now free. In fact, however, this space is not immediately reclaimable by the database it is potential free space that is reclaimed later, once the objects have been removed for good. So, despite what the DBA_FREE_SPACE view tells you, these objects will continue to take up their original space allocation in their tablespaces until they are permanently deleted from the Recycle Bin. This deletion can occur in the following circumstances: A user can permanently remove the objects from the Recycle Bin using the PURGE command (DROP TABLE table_name PURGE). Oracle automatically removes the dropped objects in the Recycle Bin due to space pressure when Oracle doesn t have enough available free space in a tablespace to create a new object or to extend more space to an existing object. The Flashback Drop feature is automatically enabled in an Oracle Database 11g database. You don t have to configure a thing in order to use the feature. qr code generator java download How to Write and Read QR Code with ZXing in Java - Code Pool

Payload marshaling is required when the sender and receiver of a notification are in different process spaces Marshaling entails organizing and converting the data types defined in one process space for use in another Marshaling is a two-step affair: Data is packaged up on the sender s side and unpackaged on the receiver s side (Regarding the spelling of the word marshaling, in this book I use the American version with one l ) Marshaling is sometimes confused with serialization The two are related, but distinct Serialization is the process of converting a data structure into a sequence of bytes What those bytes are used for may have nothing to do with marshaling Deserialization is the reverse process of reconstituting a data structure from a sequence of bytes Data structures must be serialized before they can be written to a stream or sent over a network connection. In summary, on issuing a DROP TABLE (or DROP INDEX) command in Oracle Database 11g, the objects in question are not truly dropped. Oracle simply hides them, and you can restore them at a later point using Flashback Drop. If you truly do want to permanently remove an object, you can use the PURGE option with the DROP command: SQL> DROP TABLE test PURGE; Let s take a look at all this in a bit more detail. As mentioned earlier, the Recycle Bin is a logical structure a data dictionary table named RECYCLEBIN$. You can view the contents of the Recycle Bin for the currently logged in user via the USER_RECYCLEBIN view (RECYCLEBIN is a synonym for USER_RECYCLEBIN). Alternatively, you can view the contents of the Recycle Bin for the entire database via the DBA_RECYCLEBIN view. The following code shows an example of the latter: SQL> SELECT owner, original_name, object_name, ts_name, droptime FROM dba_recyclebin; OWNER ORIGINAL_NAME OBJECT_NAME TS_NAME ---------------------------------------------------------------------sam PERSONS BIN$xTMPjHZ6SG+1xnDIaR9E+g==$0 USERS At the user level, you simply select from the RECYCLEBIN view, instead of the DBA_ RECYCLEBIN view. You can also use the SHOW RECYCLEBIN command from SQL*Plus: SQL> SHOW RECYCLEBIN ORIGINAL NAME ---------------LOGIN_INFO TEST5 SQL> RECYCLEBIN NAME -----------------------------BIN$5oAI+vnANcTgNABgsLLCaA==$0 BIN$+rR0/h2APITgNABgsLLCaA==$0 OBJECT TYPE -----------TABLE TABLE DROP TIME ------------------2008-06-29:15:48:31 2008-06-29:15:44:53 java applet qr code Generate QR Code in java using zxing | CalliCoder
