6.2.1 Starting and terminating HiRDB Dataextractor when using TCP/IP

When TCP/IP is used, the HiRDB Dataextractor startup and termination procedures depend on whether HiRDB Dataextractor is on the data source system or the data import/file creation system.

Organization of this subsection
(1) Starting and terminating HiRDB Dataextractor on the data source system
(2) Starting and terminating HiRDB Dataextractor on the data import/file creation system

(1) Starting and terminating HiRDB Dataextractor on the data source system

In the case of data extraction from a HiRDB or ORACLE database, the HiRDB Dataextractor on the source system is started by the xtrep or xtrepO command and terminates when import or file creation processing is completed.

In the case of data extraction from a HiRDB or ORACLE database and import into XDM/RD or creation of a sequential dataset, the HiRDB Dataextractor on the source system is started by XDM/XT using the inetd OS command according to information specified in /etc/inetd.conf. HiRDB Dataextractor terminates when the import or sequential dataset creation processing is completed.

(2) Starting and terminating HiRDB Dataextractor on the data import/file creation system

The HiRDB Dataextractor on the data target/file creation system is started by the inetd OS command according to information specified in /etc/inetd.conf when extracted data is sent from a source system. When the processing is completed, HiRDB Dataextractor terminates automatically.

For details about the /etc/inetd.conf specification, see 2.2.4 Files required in order to use HiRDB Dataextractor.
