Oracle Cloud Announcement‏ (September 2017)

Image
The bottom line: Oracle are inventing aggressively on PaaS and starting to neglect the IaaS.  They are doing it by: - Reducing price of the PaaS. - More automation to reduce dramatically the TCO (migration to cloud, patches, upgrades, tuning)  - Higher performance.  - Simpler pricing and contract (a pool of cloud cedits you can use for anything)  - New autonomous database will be commercial soon. - You can bring your own license.  And again Oracle claim that their cloud is  faster than Amazon   for database   with much lower price.

Creating Far Sync instance step by step

These are the steps of creating Far Sync instance in the command line: Create 12.1 primary db Create 12.1 physical standby Create regular standby DG broker configuration modify network file (on primary and standby) and add entries for the far_sync instance, add to tnsnames.ora on Primary hosts and standby hosts: FarSyncInst =   (DESCRIPTION =     (ADDRESS_LIST =       (ADDRESS = (PROTOCOL = TCP)(HOST = FarSyncHost)(PORT = 1521))     )     (CONNECT_DATA =       (SERVER = DEDICATED)       (SERVICE_NAME = FarSyncInst)       (UR=A)     )   )     Note: (UR=A) is needed to connect to a BLOCKED unmounted database instance. Copy tnsnames.ora to new farsync server – ensure all hosts mentioned in tnsnames are written also in /etc/hosts Add to listener.ora in far sync server LISTENER =   (DESCRIPTION_LIST =     (DESCRIPTION =       (ADDRESS = (PROTOCOL = TCP)(HOST = 0.0.0.0 )(PORT = 1521))       (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))     )   ) SID_LIST_LISTENER=
