A User Agent, like a web browser, uses HTTP to request a HTML document
Php Funzione mail()
In programming the danger of exploring the small details of coding is that you get obsessed with every line of code you write, thereby greatly reducing productivity.
In general, is not worth obsessing over code. On the other hand you should code with deliberation and intent. Steven Feurstein Oracle Magazine July /August 2004 A User Agent, like a web browser, uses HTTP to request a HTML document

Home >Oracle > Using data pump in interactive mode
Among all differences from the notorious exp utility, Data Pump, available allows to be run on backoground, to disconnect the client from the server without interrupting the import or export operation, to stop and restart the job. Scope of this example is using data pump to export all the objects of schema TEST using a parameter file and checking out the intercative mode main commands. 1) Make sure that user TEST has oracle grants on read and write on a directory. SYSTEM can create register on the database a directory, previously created with file system commands. create directory ora_dp as 'server1/u01/oracle_dp/#') Then SYSTEM allows Test read and write privileges : grant read,write on directory ora_dp to TEST) 2) Place the following parfile dp.par in the directory where you will issue the data pump command.
dumpfile=mydumpfile
3) Start datapump
directory=oracle_dir parallel=2 status=2 job_name=dpmyjob
server1/u01/oracle_dp/# expdp parfile=dp.par
On screen data pump shows the current status:
Job: MYJOB
Operation: EXPORT Mode: SCHEMA State: EXECUTING Byte elaborati: 0 Degree: 2 Job Error Count: 0 Dump dile: server1/u01/oracle_dp/MYDUMPFILE.DMP s byte scritti: 4.096 4) Data pump allows you to step into interactive mode with CRT+C while the job is still going on background. 5) The command EXIT_CLIENT for instance allows to exit and run, for example, some operative systems task. 6) To get back into the interactive mode use the ATTACH parameter:
server1/u01/oracle_dp/# expdp attach=dpmyjob
7) From interactive mode, you can check the current state: Export> Status 8) CONTINUE_CLIENT close the interactive mode prompt Export>CONTINUE_CLIENT 9) From interactive mode you actually can stop the job: Export> STOP_JOB 10) To restart a job use ATTACH parameter:
server1/u01/oracle_dp/# expdp attach=dpmyjob
9)Eventually, to kill permanently a job use KILL_JOB from the interactive mode prompt: Export> STOP_JOB 10) To monitoring data pump process DBA_DATAPUMP_JOBS and DBA_DATAPUNP_SESSION.
