Known Issues for Release 2.4.0.0.0

For additional information about known issues for this patch, refer to My Oracle Support Note 888888.1. The following summarizes the known issues for release 2.4.0.0.0:

  • By default, Oracle installs Enterprise Manager DB Console for the database. For Grid Infrastructure patching, Oracle stops all DB Consoles. However, if you installed the Oracle Database Grid Control 12c agent, then it remains operational. If you have installed Oracle Database Grid Control 12c, then run the command emctl stop agent to stop the Oracle Database Enterprise Manager Agent before applying Grid Infrastructure patching. This avoids running into the issue – copy failed for crsctl.bin.

  • It is not necessary to run emctl stop dbconsole, because the patching process stops the console. Intermittently, some DB Console processes continue running, and Grid Infrastructure patching fails because a copy operation for crsctl.bin failed. If this happens, then ensure that the DB Console process is stopped before performing Grid Infrastructure patching.

  • After the infrastructure is updated, run dmidecode -t 1|egrep Serial Number|Version|Product Name|SKU Number on both nodes. If either node responds with a Not Available message, then reboot the node. This issue should be resolved in this release.

  • After the infrastructure updates, run fwupdate list controller | grep –v Intel on both nodes. If no information appears under FW Version for SAS LSI Logic 0x0072 Type Manufacturer Model controllers, then reboot the node. The firmware version should be 11.05.02.00. This issue should be resolved in this release.

  • In deployments for the version prior to Oracle Database Appliance 2.3, the parameter use_large_pages is set to TRUE. For new deployments, Oracle adopts the best practice of setting use_large_pages to ONLY. If you did not properly size your environment based on Appendix C of the Oracle Database Appliance Getting Started Guide and your database has a larger SGA, then you might see related messages in your alert log file. Oracle does not recommend that you revert the setting of use_large_pages to TRUE. Instead, Oracle recommends that you let the system notify you with the early warning that your database might run into memory issues; eventually this limitation will affect your system's performance. In this case, Oracle recommends that you avoid creating and starting additional databases.
