temporary system tablespace. The default temporary system tablespace created with the database is named TEMPSPACE1.User temporary tablespaceThe user temporary tablespace stores declared global temporary tables. The user's temporary tablespace does not exist when the database is created. At least one user temporary tablespace should be created to allow the definition of declared temporary tables. The user's temporary tablespace is optional and is not created by default.
operation is very large, it will lead to competition for logs, resulting in very slow operations. If you insert, update, or delete a table without logs, the log is rarely used. However, if the operation fails, the table cannot be rolled back. Therefore, the consistency is not guaranteed and the table can only be deleted and rebuilt.
4) Create Table-level locks for tables to minimize the number of locks. Because the maximum number of database locks is

applied separately. The lock IS not applied only when the UR isolation level IS used. This ensures that the data read by different applications and users is consistent.2 ). while supporting high concurrency, DB2 and Oracle have different locking mechanisms: Oracle uses design techniques such as intention locks and lock marks on data rows, this reduces the cost of Oracle's Row-Level Lock maintenance and makes it advantageous in database concurrency co
Tags: database DB2What isREORG?We know that there are many tables in the database, and we may often need to do operations such as pruning table data, and after a series of changes, logically contiguous data may be on a discontinuous physical data page, especially when many insert operations create overflow records. When you organize data in this way, the database manager must perform additional read operations to access the sequential data. When you delete
