  1. 7. Oracle networking • Cấu hình cho listener : Oracle Listener là một chương trình liên tục lắng nghe các yêu cầu kết nối với CSDL Oracle. Để Oracle Listener biết cấu hình hệ thống, Oracle Listener sẽ đọc cấu hình trong thư mục: $ORACLE_HOME/network/admin • /u01/app/oracle/product/10.1.0.2.0/network/admin/listener.ora • Files /etc/hosts listener.ora tnsname.ora

  2. listener.ora CPA A • # listener.ora Network Configuration File: /u01/app/oracle/product/10.1.0.2.0/network/admin/listener.ora • # Generated by Oracle configuration tools. SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = AMSS) (ORACLE_HOME = /u01/app/oracle/product/10.1.0.2.0) ) ) LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = server11)(PORT = 1521)) (ADDRESS = (PROTOCOL = TCP)(HOST = server12)(PORT = 1522)) ) ) )

  3. listener.ora CPA B • # listener.ora Network Configuration File: /u01/app/oracle/product/10.1.0.2.0/network/admin/listener.ora • # Generated by Oracle configuration tools. SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = AMSS) (ORACLE_HOME = /u01/app/oracle/product/10.1.0.2.0) ) ) LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = server21)(PORT = 1521)) (ADDRESS = (PROTOCOL = TCP)(HOST = server22)(PORT = 1522)) ) ) )

  4. tnsname.ora # tnsnames.ora Network Configuration File: /u01/app/oracle/product/10.1.0.2.0/network/admin/tnsnames.ora # Generated by Oracle configuration tools. AMSS2 = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = server22)(PORT = 1522)) ) (CONNECT_DATA = (SID = AMSS) (SERVER = DEDICATED) ) ) AMSS1 = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = server12)(PORT = 1522)) ) (CONNECT_DATA = (SID = AMSS) (SERVER = DEDICATED) ) )

  5. tnsname.ora tiếp AMSS = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = server12)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = AMSS) ) )

  6. 8. Oracle replication • SERVER B • SQL>update global_name set global_name = ‘AMSS2.WORLD’ • SERVER A ( MASTER SITE ) • SQL>update global_name set global_name = ‘AMSS1.WORLD’ run script SQL>@replicate SQL>@addrepjtable

  7. Oracle replication monitor • $oemapp console
