| firstchild| Rightsib | |-----------|-----------|-----------| Where data is the domain, FirstChild is the pointer field, storing the node's first child node storage address, Rightsib is the pointer field, storing the node's right sibling node storage address. The structure definition code is as follows. typedef struct CSNODE { Telemtype data; struct Csnode *fir

When exporting data for a oracle11.2.0.2 server, the "EXP-00003: storage definition for segment (0,0)" error was reported. The initial analysis is due to the fact that the data table is empty and the table causes the problem.An empty table cannot be exported when Oracle 11G is exported with exportThere is a new feature in 11GR2 that does not allocate segment when

When I back up an oracle tableWhen you export a table with a clob type field: EXP-00003: A storage definition of segment (11,419) not foundOthers can be exported normally.

The following issues occurred when using the Oracle database for the first two days, using the DBA user to export table structures in the tool in PL/SQL, when exporting tables:A lot of table "error (EXP-00003) did not find the segment (0,0) storage Definition", the results, after finding relevant data, comparison table structure, and finally found that all reported this error table is empty table---the tabl

Strict mode (strict mode), all variable definitions need to use the var keyword. If you do not use strict mode, then when the JS program to an undefined variable to assign a value, the program will be in the JS global object to create a name and the same variable property, that is, create a new global variable. This practice will bring a lot of problems (for example, a number of JS program to produce global variable pollution, etc.), to the maintenance of the later bring no small trouble, so in

While most recent news about Microsoft has focused on Windows 8 and Surface tablet devices, Windows Storage Server 2012, which was included in a new version of Windows Server 2012 a few weeks ago, also deserves our attention. This product is categorized in two versions, working with the Standard Edition. The workgroup version is primarily for small groups of user

Redundancy of storage spaceIn the high-availability architecture of the storage controller server, there is a difference in the degree of redundancy that is achieved by using a different number of JBOD or different ways of storage space layout. If you cannot turn on storage
