For late-breaking updates and best practices about preupgrade, post-upgrade, compatibility, and interoperability discussions, refer to Note 601807.1 on My Oracle Support (formerly OracleMetaLink) (
https://support.oracle.com) that links to "Oracle 11gR1 Upgrade Companion" page.
Use the Oracle Fusion Middleware Web Tier Utilities 11g (18.104.22.168.0) media to install Oracle HTTP Server.
When you start upgrading second node from Oracle Database 10g Release 2 to Oracle Database 11g, an error message is displayed while copying files during the upgrade process.
Workaround: Run the upgrade session from the node on which you initially installed Oracle RAC.
This issue is tracked with Oracle bug 6501871.
Oracle database instance and listeners are not started after the installation is complete if you perform any of the following tasks:
Oracle 11g Database installation or upgrade on a cluster into an existing
ORACLE_BASE directory that has other Oracle home(s)
Custom installation to install additional components in an existing Oracle RAC database home on Oracle Clusterware
You can run the
/bin/srvctl command to display the status of Oracle database instance and listeners. When you try to start the listener for the remote node, the following error message is displayed:
TNS-01151: Missing listener name, LISTENER_NODE_NAME, in LISTENER.ORA
Workaround: Complete the following procedure for the remote node(s) on which the listener displayed an error message:
For each node selected in step 1, use the following command to backup
/network/admin.orig before proceeding with the installation:
$ cp -R Oracle_home/network/admin Oracle_home/network/admin.orig
For each node selected in step 1, use the following command to restore
/network/admin after completing the installation:
$ cp -R Oracle_home/network/admin.orig Oracle_home/network/admin
Run the following command on local node for each nodes selected in step 1:
$ Oracle_home/bin/srvctl start listener -n node_name
If the Oracle Database instance for the remote node is down because of the listener, then start the Oracle database an instances that are down using the following command:
$ Oracle_home/bin/srvctl start databse -d database_name
These issues are tracked with Oracle bugs 6412150 and 6612571.
If you install Oracle Clusterware on share Oracle home, the
/etc/oratab file lists multiple Automatic Storage instances.
Workaround: Oracle Universal Installer detects this issue during the pre-requisition checks. You can either edit the
/etc/oratab file or ignore the error during installation.
The issue is tracked with Oracle bug 5942123.
If you have downloaded Oracle Database 11g Release 1 before January 18, 2008 from Oracle Technology Network or media and were prompted to execute the
rootpre.sh script, then you must install the
rootpre_aix.zip file available on Oracle Technology Network:
New customers do not have to download the
rootpre_aix.zip file. You can directly download the Oracle Database 11g release 1 software available on Oracle Technology Network:
When upgrading Oracle Clusterware from release 10.2.0.4 to release 22.214.171.124, the
rootupgrade script gives the following error:
Failed to retrieve VIP details.
In addition, the output of
crs_stat -t shows that the Oracle Notification Service resource is offline on one or more nodes.
/jdk/jre/bin/sovvm.bak before running the the rootupgrade script.
This issue is tracked with Oracle bug 7034395.
The following sections contain information about issues related to Oracle Database 11g and associated products:
When using Oracle 11g Release 1 Direct NFS client, the
ORA-494 errors are displayed intermittently under certain load conditions.
Workaround: Oracle recommends that you apply the patch mentioned in the Oracle bug 6530092 to Oracle Database 11g Release 1 installation. The Oracle bug contains the details of the patch and application instructions.
This issue is tracked with Oracle bug 6530092.
Monitoring in Memory Access Mode is not supported for this release on this platform. This option is disabled by default. If you enable this option, then the performance charts are not displayed and an error connection to collector memory is displayed at times.
Workaround: Use SQL Mode monitoring instead of Memory Access Mode.
This issue is tracked with Oracle bug 6498439.
OC4JADMIN user is deactivated during the Oracle Database 11g installation process. After the installation is complete, you must modify the
$ORACLE_HOME/oc4j/j2ee/OC4J_SEARCH/config/system-jazn-data.xml file. Replace the following content of the file:
<user deactivated="true"> <name>oc4jadmin</name> <display-name>OC4J Administrator</display-name> <description>OC4J Administrator</description>
<user> <name>oc4jadmin</name> <display-name>OC4J Administrator</display-name> <description>OC4J Administrator</description>
Use the following commands to restart the Oracle Ultra Search middle tier in the Oracle Database:
$ $ORACLE_HOME/bin/searchctl stop $ $ORACLE_HOME/bin/searchctl start
When adding a node to the Oracle Clusterware in a vendor cluster environment that uses host names with fully qualified domain names, the
rootaddnode.sh utility displays the following error message:
PRKO-2006 : Invalid node name: NODE_NAME
Workaround: For each node that is being added to the Oracle Clusterware, run the following command:
srvctl add nodeapps -n node_name_without_fully_qualified_ domain_name -A node-vip/netmask/Interfaces
Note:To find the node name and virtual IP address/netmask/interface to be used for the newly added nodes, you can refer to values set for the following variables in the
CRS_NEW_NODE_NAME_LIST= CRS_NEW_NODEVIPS= NETMASK= NETIFs=
To find if the vendor clusterware is configured, run the
$ORA_CRS_HOME/bin/lsnodes command. The
lsnodes command displays the list of nodes in this case.
You can refer to
rootaddnode.sh for the value that
ORA_CRS_HOME is set to.
This issue is tracked with Oracle bug 6617499.
Due to a JDK bug, online help pages appear blank when running Java applications such as, Oracle Database Configuration Assistant or Oracle Database Upgrade Assistant in a
zh_TW environment (Chinese, Taiwan locale).
This issue is tracked with Oracle bug 7408773.
Due to an IBM JDK issue, Oracle Database Configuration Assistant fails to re-register Oracle Database with Oracle Internet Directory, resulting in one of the following error:
Wallet Exception - Could not open wallet - Check password
Unable to create database entry in directory service - Wallet Exception - ArrayIndexOutOfBoundsException. error.
Workaround: Make a copy of the Oracle Database Configuration Assistant script, then edit the last line of the script to pass
-Xjit:disableTreeSimplification flag to Java command line.
This issue is tracked with Oracle bug 7443504
This section lists the following correction to the installation guide for AIX:
The "Operating System Requirements" section in chapter 2 of the Oracle Database Installation Guide for AIX 5L Based Systems (64-Bit), lists incorrect value
AIX 5L version 5.3, TL 05, Service Pack 06.
The correct value is
AIX 5L version 5.3, TL 05, Service Pack 06 or later.
Appendix H, "Database Limits" of Oracle Database Administrator's Reference for Linux and UNIX guide states incorrect value for control files as 10000 database blocks. The correct value is 25000 control file blocks with a block size of 4096 bytes.
The last two paragraphs of Appendix A.2.4, "Input-Output Slaves" of Oracle Database Administrator's Reference for Linux and UNIX guide have been modified as follows:
There are times when you must turn off asynchronous I/O. For example, if instructed to do so by Oracle Support for debugging. You can use the
TAPE_ASYNCH_IO parameters to switch off asynchronous I/O for disk or tape devices.
TAPE_ASYNCH_IO support is only available when the Media Manager software supports it and for Recovery Manager, if
BACKUP_TAPE_IO_SLAVES is true.
DBWR_IO_SLAVES parameter to greater than 0 only if the
DISK_ASYNCH_IO parameter is set to false. Otherwise, the database writer process becomes a bottleneck. In this case, the optimal value on AIX for the
DBWR_IO_SLAVES parameter is 4.
