Version Bug ODBC Recordset. Oracle ODBC driver Oracle ODBC driver in Migrating an Oracle Database 11 g Release 2 Oracle ODBC driver after upgrade to Array insert of type LOB resulted in inserting the last element into all the rows. ODBC data Source Administrator never use to show the fully qualified service name in the drop down box.
Oracle ODBC driver use to throw pop up window of change-password repeatedly when database password expired. The threaded version of the application use to take more time than the process version. Memory leak was reported in the ODBC driver while returning a result set from a stored procedure.
ODBC driver use to fail in updating the output parameter of a stored procedure when it contained a large CLOB parameter as the input parameter. ODBC driver use to fail in updating the output parameter of a stored procedure when it contained a large CLOB parameter as an input parameter. ODBC driver use to return old data on requering the data for a read-only connection. This problem appears only on the Solaris platform, but the software fix is generic.
ODBC driver use to result in an application crash while executing a stored procedure having a large number of parameters. This is a port specific Linux and Solaris bug. ODBC driver use to report a crash for executing queries in a multithreaded application. Access to Oracle Support.

Do not use the installation media from a later release to remove Oracle software from an earlier release. For example, do not run the deinstall from the After upgrading to Oracle Database 12 c Release 1 One workaround for this issue is to apply the patch for bug This workaround eliminates the need for the patch for bug Gathering statistics for tables that have all of the following scenarios can also cause suboptimal plans:.
After a downgrade to In Then, follow the steps for catrelod. The pre-upgrade tool, preupgrd. For example:. The workaround is to manually create the output directory before running preupgrd.
If the root configuration script is run from a directory for which the user running the script does not have write permission or the file system does not have enough space to create the file containing the exported contents of the Oracle Local Registry, then the script will fail with the following error reference Bug :. To workaround this problem, run the configuration script from a directory to which the installing user has write permission.
The file system must also have sufficient space to write the exported file. In an Oracle Exadata environment, if the database being upgraded has a large number of tablespaces for example, 64, and corresponding data files and if each tablespace has one data file stored on Oracle ASM, when the Database Upgrade Assistant DBUA starts up the service it may fail or take a long time to start due to the large number of data files reference Bug This book is part number E When downgrading from release Oracle Database 12 c to This patch can be applied to the You must apply the fix in the original release When a node crash occurs during an upgrade, a -force upgrade can be performed to upgrade a partial cluster minus the unavailable node reference Bug After performing a -force upgrade, the node list of the Grid home in inventory is not in sync with the actual Oracle Grid Infrastructure deployment.
The node list still contains the unavailable node. Because the node list in inventory is incorrect, the next upgrade or node addition, and any other Oracle Grid Infrastructure deployment, fails. After performing a -force upgrade, manually invoke the following command as a CRS user:. When upgrading from release Oracle Database 11 g Release 1 You may ignore this error.
However, ensure that the Oracle ASM disks are visible using the default discovery string. The following sections discuss components that are not available or are restricted in this release of Oracle Database 12 c Release 1 The following is a list of features that are not available or are restricted for a multitenant container database CDB in this release of Oracle Database 12 c Release 1 The following is a list of components that are not available or are restricted in this release of Oracle Database 12 c Release 1 Interval partitioning is not supported with XMLIndex.
XMLIndex only supports range, list and hash partitioning schemes. In the initial release of Oracle Database 12 c , replay is not supported for Application Continuity when using proxy authentication. The connections between the ONS server in the database tier and the notification client in the mid-tier are usually not authenticated.
It is possible to configure and use SSL certificates to setup the authentication but the steps are not clearly documented. Update the ONS configuration file on all nodes in the database tier to specify the location of the wallet created in Step Add the walletfile parameter to the ons.
If you are running a client-side ONS daemon on the mid-tier, there are two possible configurations:. ONS started standalone like using onsctl , which uses ons.
This involves modifying the opmn. The client-side ONS daemon can potentially run of different machines. Copy the wallet created in Step 1 to those client-side machines and specify the path on that client-side machine in the ons. Alternatively, you can specify the following string as the setONSConfiguration argument:.
The Java properties file should contain one or more of the ONS Java properties listed below, but at least the oracle. The values for these Java properties would be similar to those specified in the "Remote ONS Subscription" subsection previously noted in this step:.
The privilege can be granted by the database administrator using the following call:. The host parameter can be a host name, an IP address, a domain name, or an IP subnet.
For additional details, refer to the Oracle Database Security Guide. Oracle Database 12 c introduces behavior changes for your database in addition to new features. Changes in behavior include deprecated and desupported initialization parameters, options, syntax, and the deprecation and desupport of features and components. For more information, see the Oracle Database Upgrade Guide. This section describes some of the differences in behavior between Oracle Database 12 c Release 1 The majority of the information about upgrading and downgrading is already included in the Oracle Database Upgrade Guide.
To avoid this, OTT has to be invoked, as shown below, in the Windows batch scripts. See platform-specific release notes for details. Scoring capabilities in the storage layer permit very large data sets to be mined quickly, thus further increasing the competitive advantage already gained from Oracle in-database analytics.
This error is expected and can be ignored. It does not affect Oracle Database Vault functionality in any way.
If there are invalid objects, then run the utlrp. If the utlrp. If the script terminates abnormally without giving any instructions, then run it again. Upgrade to Oracle Enterprise Manager to 12 c Release 2 Run discovery or manually add the target to Oracle Enterprise Manager after creating the database using the Grid Control or Cloud Control console.
Note that if you do not upgrade to Oracle Enterprise Manager to 12 c Release 2 Go to the Targets page and click All Targets. Select a menu item, click Target Setup , and then click Monitoring Configuration. Oracle Database 12 c Release 1 Oracle Database 12 c offload libraries are present only in the Oracle Exadata Storage Server software version Therefore, smart scan offload for Oracle Database 12 c is available only with Exadata Storage Server software version You must register online before using My Oracle Support.
Some non-Oracle Grid Infrastructure usage of mount points prevents unmounts and volume disables in the kernel reference Bug Examples include:. If this reflects your situation, ensure that you discontinue usage of these features before trying to initiate a stack shutdown, file system unmount, or volume disable. Additionally, certain user space processes and system processes may use the file system or volume device in a way that prevents the Oracle Grid Infrastructure stack from shutting down during a patch or upgrade.
The feature remains the same, only the name has changed. References to Oracle inter Media were replaced with Oracle Multimedia, however some references to Oracle inter Media or inter Media may still appear in graphical user interfaces, code examples, and related documents in the Oracle Database 12 c Release 1 Note the following when working with Oracle Text.
An Oracle Text knowledge base is a hierarchical tree of concepts used for theme indexing, ABOUT queries, and deriving themes for document services. The following Oracle Text services require that a knowledge base be installed:. If you plan to use any of these Oracle Text features, then you should install the supplied knowledge bases, English and French, from the Oracle Database Examples media, available for download on OTN.
Note that you can extend the supplied knowledge bases, or create your own knowledge bases, possibly in languages other than English and French. For more information about creating and extending knowledge bases, refer to the Oracle Text Reference. For information about how to install products from the Oracle Database Examples media, refer to the Oracle Database Examples Installation Guide that is specific to your platform.
For tables created prior to When using or refreshing certain materialized views, you must ensure that your NLS parameters are the same as when you created the materialized view. Materialized views that fall under this restriction contain the following constructs:.
Expressions that may return different values, depending on NLS parameter settings. The result of this equijoin depends on collation which can change on a session basis, giving an incorrect result in the case of query rewrite or an inconsistent materialized view after a refresh operation. Expressions that generate internal conversion to character data in the select list of a materialized view, or inside an aggregate of a materialized aggregate view.
Databases that enabled tablespace encryption in Oracle Database 11 g Release 1 This ensures that a unified TDE tablespace and column encryption key is available for use if a rekey command was not previously executed. In Oracle Database 12 c , this can be done with the following commands:. This section lists known bugs for this release.
A supplemental list of bugs may be found as part of the release documentation specific for your platform. In such cases, the failover fails with the ORA error. Workaround: Shut down all nodes at the standby database; then mount one node and rerun the failover DDL.
If the failover operation continues to fail, then refer to steps 8 and 9 in Section 9. If you upgrade your database to Oracle Database 12 c Release 1 This occurs because, in a The error occurs because the PDB is automatically executing an old program which comes from the upgraded database. The problem does not exist for a brand new PDB. Shared servers cannot be enabled or disabled at the pluggable database PDB level.
Therefore, either all PDBs or none of the PDBs must use shared servers unless one of the following workarounds is used. Workaround: Any of the following workarounds can be used if only some PDBs in a multitenant container database CDB should use shared servers:. If the connections that should be dedicated share a sqlnet. This may not be sufficient when creating a multitenant container database CDB with a higher number of pluggable databases PDBs.
Higher values may be necessary depending on the workload. Workaround: Re-create the temporary files. Per-PDB session counts or limits are not sent to the listener. Thus, it is possible for a listener to direct a connection to an instance where the PDB is at the limit while the PDB on a different instance is not at the limit. Note that this only matters if the PDB is at its session limit. If it is not, there is no impact from this bug.
Workaround: Do not use per-PDB session limits. Once chosen, you cannot change the option for the lifetime of the CDB. When a PDB with an offline tablespace is plugged into a CDB, the tablespace cannot be brought online after the plug in is done. Currently, a warning is raised during plug in time to indicate this limitation. Workaround: Before plugging in a PDB make sure there are no offline tablespaces.
If there are any offline tablespaces make sure they are brought online before doing the plug in. If the primary database is a CDB and the control file is re-created such that it does not have all of the data file names, it will crash or interrupt the recovery process on the standby databases. Workaround: Take the following steps on the primary database:.
Execute database recovery for the missing files on the primary database and open the database and the PDBs. When running the deinstallation tool to deinstall the database, you will be prompted to expand the Oracle home and to select a component. If you select the top level component, Oracle Database Server , and do not select the Oracle home, OUI does not show the message to run the deinstall utility and proceeds with the deinstallation of the database.
Workaround: Run the deinstallation tool to deinstall the Oracle home. That is, each consecutive "? This incorrect format can cause inconsistent behavior during query translation.
Workaround: The incorrectly documented behavior will be fixed in a future release. Any translation with parameters working in Oracle Database 12 c is a coincidence and is not consistent. Any translator relying on binds may be impacted. Several changes were made to local transaction processing for compliance with the JDBC spec 4. If setAutoCommit true is called and a local transaction exists, the transaction is automatically committed in earlier releases, no action was taken.
It is possible that your application will have these situations and it may be difficult to immediately change the software. Find centralized, trusted content and collaborate around the technologies you use most. Connect and share knowledge within a single location that is structured and easy to search. Just a simple question I guess. Here, we've been using Oracle 10g database with ojdbc6 for Oracle 11g Now, my questions.
If I upgrade my application server to use ojdbc7 for Oracle 12c, is it too risk? Does the Oracle maintains compatibility of their drivers with previous versions?
