You enable debugging of the directory server by changing the attribute orcldebugflag , which is now in the instance-specific configuration entry, which has a DN of the form:. You can change orcldebugflag either by using the Server Properties page, Logging tab, in Fusion Middleware Control or by using ldapmodify.
For example, you could use the following LDIF file to configure the Oracle Internet Directory instance in system component oid1 for heavy trace debugging. You enable debugging of the replication server by changing the attribute orcldebuglevel in the replication configuration set.
Table , "Replication Configuration Set Attributes" lists and describes the attributes of the replication configuration set, which has the following DN:. You can use either ldapmodify or the Shared Properties, Replication tab, in Fusion Middleware Control to change orcldebuglevel.
Several Oracle Internet Directory administration tools and bulk tools take a connect argument that specifies the Oracle Database to connect to. In 11g Release 1, you must use the connect argument to specify the database. As a result, the path names of most configuration files and log files are different than in 10g Table A-2 lists some examples:. Section 7. The attribute orclAudFilterPreset has replaced the audit levels used in 10g Referential Integrity has be en completely reimplemented.
A separate Replication page enables you to adjust attributes that control the replication server. You can now use LDAP-based replication for multimaster directory replication groups. You no longer need Oracle Database Advanced Replication-based replication for this purpose. Oracle Database 12c - what is new? DataGuard enhancements - Detection of gasps and automatic resolution. DataGuard improvements - Realtime apply and log compressions - Fast start failover added.
Active DataGuard added - Standby Database can now be queried whilst redo apply is active. Backup and Recovery - Block level recovery - Improved reporting and automation.
Upgrade Assistants are being used to facilitate the process of upgrade ad provide more options and paths for performing the tasks related to upgrades.
The same goes for data migration between the different Oracle versions if necessary. Therefore, it makes good sense to get back your money's worth by going for the upgrade to Oracle 12c. Better Support Experience : The support for 12c seems to be better than that for older releases.
Even though the Extended Support programs related to 11g provided plenty of runway for 12c upgrade, the support resources are certainly more focused on the release of this version of Oracle. As only a negligible part of annual maintenance fees directly applies to software fixes, it is a good idea to maximize the value of support dollars by upgrading to newer versions as soon as possible.
This version offers reduced efforts and time, improved management, and more effectiveness for database upgrades, recovery, backup, etc. Better server resource utilization leads to enhanced levels of consolidation in 12c. Additionally, smart compression, storage tiering, and other related features automatically compress and arrange data based on its activity and age.
They allow for large quantities of memory-based data caching that goes beyond traditional buffer caches. The data thus cached can be saved in compressed columnar formats. The result lies in improved performance and better optimization of server resources. These features are elementary to implement as they are woven into database kernels and are transparent to applications. In case you have been thinking of a 12c upgrade, then it is indeed time to go through its functions, tools, and features in more significant detail.
We have tried our best to give you a closer look at why it is essential to prepare, upgrade, migrate, manage, and report to new 12c environments. In this article, we have thrown light on the difference between Oracle 11g and 12c, the difference between Oracle 10g vs.
Alongside, we have shed light upon oracle 11 g new features, Oracle 10g new features, and the new features Oracle 12 c for your benefit. In case you have any further inputs related to Oracle 12c vs. We shall wait to hear from you. Now 12 c cloud you can unplug your database from on premise and plug it to cloud at anytym without any pain.
Therefore 11g provides better performance and its release 2 has been geared for newer operating systems such as Windows 7, Server and latest versions of Linux, Unix, Solaris, etc.
Compared with 10g, 11g provides more simplified, improved and automated memory management and better ability to diagnose faults through inbuilt infrastructure to prevent, detect, diagnose, and help resolve critical database errors, as well as, low database performance issues.
It provides invisible indexes, virtual columns, table partitioning and the ability to redefine tables which have materialized view logs whilst online. A major difference in the two are the new security features found in 11g such as better password-based authentication with mixed case passwords, encryption on tablespace-level and enhancements for data pump encryption and compression. All in all, 11g is a good upgrade from 10g with many positive enhancements on an evolving technology.
The technical documentation which was good in 10g has become even better in 11g, a significant benefit for the DBAs, who depend on it daily.
