    You can create/drop tables in PL/SQL block with Execute immediate command
    actually any programming language follows pre/post validations for host variable
    here pre checking wl be done,so at the time of compilation we have to submit all host variables,but we can't with ddl stms,so where ever we keep Execute immediate stmt that stmt wl be validate at runtime only.
    this is nothing but Dynamic SQL.previously we are using in-built pakage ,now execute immediate command .

Background Process in ORACLE Database

Background Process in ORACLE Database Database Writer Process (DBWn) Log Writer Process (LGWR) Checkpoint Process (CKPT) System Monitor Process (SMON) Process Monitor Process (PMON) Recoverer Process (RECO) Job Queue Processes Archiver Processes (ARCn) Queue Monitor Processes (QMNn) Database Writer Process (DBWn) The database writer process (DBWn) writes the contents of buffers to datafiles. The DBWn processes are responsible for writing modified (dirty) buffers in the database buffer cache to disk. Although one database writer process (DBW0) is adequate for most systems, you can configure additional processes (DBW1 through DBW9 and DBWa through DBWj) to improve write performance if your system modifies data heavily. These additional DBWn processes are not useful on uniprocessor systems. When a buffer in the database buffer cache is modified, it is marked dirty. A cold buffer is a buffer that has not been recently used according to the least recently used (LRU) algorith...
