Helping colleagues in OTN Forum I found a issue that have not been solved yet, but we must be aware of this issue before performing implementation.
When you are using policy-managed database Oracle Manage all instance automatically on demand without dba intervention. For the whole thing work well is mandatory use SCAN (IP and SCAN Listeners) and VIP (IP and Local Listeners) database use these resource to automatically register it's own services and that's way how the Oracle client will find a Oracle Instance.
When you Configure a SHARED SERVER on Policy-Managed Dababase one question arise:
SHARED SERVER don't use Parameter LOCAL_LISTENER to register database on Listener, but it use DISPATCHERS parameter.
DISPATCHERS parameter is NOT Like LOCAL_LISTENER parameter which automatically updated by Database Agent. Then you must set DISPATCHERS manually using VIP of current Node on each Instance. As explained in note How To Configure Shared Server Dispatchers For RAC Environment [ID 578524.1]. BUT this will work only if you have a ADMIN-MANAGED database because instance is fixed on that node.
Policy-managed database has not fixed a instance on specific node and also has not a specific INSTANCE_NAME, because INSTANCE_NAME can be changed automatically on demand or when you change configuration of your SERVER POOL.
The BIG QUESTION:
How configure DISPATCHERS parameter when database is POLICY-MANAGED ? Since DISPATCHERS can't be automatically configured dynamically, but the INSTANCE is dynamic and can be reloacated to any node on that server pool.
When I get the anwser I'll post here Oracle Solution. (If someone already has the answer please post here)
Recently we discovered a possible vulnerability on SCAN Listener, so we opened SR and Oracle give us a solution.
I recommend all apply this security. “As far as I know only the availability can be affected, none concern about data integrity” .
Thread: How prevent REMOTE LISTENER register on SCAN LISTENER
Oracle Security Alert for CVE-2012-1675
This security alert addresses the security issue CVE-2012-1675, a vulnerability in the TNS listener which has been recently disclosed as “TNS Listener Poison Attack” affecting the Oracle Database Server. This vulnerability may be remotely exploitable without authentication, i.e. it may be exploited over a network without the need for a username and password. A remote user can exploit this vulnerability to impact the confidentiality, integrity and availability of systems that do not have recommended solution applied.
Affected Products and Versions
Oracle Database 11g Release 2, versions 18.104.22.168, 22.214.171.124
Oracle Database 11g Release 1, version 126.96.36.199
Oracle Database 10g Release 2, versions 10.2.0.3, 10.2.0.4, 10.2.0.5
Recommendations for protecting against this vulnerability can be found at:
- My Oracle Support Note 1340831.1 for Oracle Database deployments that use Oracle Real Application Clusters (RAC).
- My Oracle Support Note 1453883.1 for Oracle Database deployments that do not use RAC.
Please note that Oracle has added Oracle Advanced Security SSL/TLS to the Oracle Database Standard Edition license when used with the Real Application Clusters and Oracle has added Oracle Advanced Security SSL/TLS to the Enterprise Edition Real Application Clusters (Oracle RAC) and RAC One Node options so that the directions provided in the Support Notes referenced above can be applied by all Oracle customers without additional cost.
Note: Please refer to the Oracle licensing documentation available on Oracle.com regarding licensing changes that allow Oracle Advanced Security SSL/TLS to be used with Oracle SE Oracle Real Application Clusters and Oracle Enterprise Edition Real Application Customers (Oracle RAC) and Oracle RAC OneNode Options.
Due to the threat posed by a successful attack, Oracle strongly recommends that customers apply this Security Alert solution as soon as possible.
Starting with Oracle Automatic Storage Management 11g Release 2 (188.8.131.52), Oracle ACFS supports RMAN backups (BACKUPSET file type), archive logs (ARCHIVELOG file type), and Data Pump dumpsets (DUMPSET file type). Note that Oracle ACFS snapshots are not supported with these files.
ASM best practices we recommend to have two ASM disk groups:
DATAOH Diskgroup contains:
- Database files (Database files must be stored directly in ASM and not on ACFS)
- Oracle Clusterware files (OCR/Vote files)
- ASM Spfile
- ADVM volumes/ACFS filesystems for database related data or general-purpose use
This disk group will be used to store database recovery related files; such as archived log files, RMAN backups, and Flashback logs
- Datapump dumpsets , RMAN backup files, etc. This was supported in ACFS 184.108.40.206 and above; however, ACFS does not currently support snapshots of filesystems housing these files.
- Additionally, database ORACLE_HOME backups (possibly zipped backups), can stored in a filesystem carved from the FRA disk group
