1 Certification Information

The latest certification information for Oracle Database 10g release 2 (10.2) is available on OracleMetaLink at:

http://metalink.oracle.com

Products and Components Not Certified at the Time of This Publication

At the time of this publication, Oracle Cluster File System version 2 is not certified on Red Hat Enterprise Linux 4.0 and SUSE Linux Enterprise Server 9.

2 Raw Devices on Red Hat Enterprise Linux 4.0

When you restart a Red Hat Enterprise Linux 4.0 system, raw devices revert to their original owners and permissions by default. If you are using raw devices with this operating system for your Oracle files, for example, for ASM storage or Oracle Clusterware files, you need to override this default behavior. To do this, add an entry to the /etc/rc.d/rc.local file for each raw device containing the chmod and chown commands required to reset them to the required values.

As an example, here are sample entries in a /etc/rc.d/rc.local file that control the restart behavior of raw devices for two ASM disk files (/dev/raw/raw6 and /dev/raw/raw7), two Oracle Cluster Registry files (/dev/raw/raw1 and /dev/raw/raw2), and three Oracle Clusterware voting disks (/dev/raw/raw3, /dev/raw/raw4, and /dev/raw/raw5):

# ASM
chown oracle:dba /dev/raw/raw6
chown oracle:dba /dev/raw/raw7
chmod 660 /dev/raw/raw6
chmod 660 /dev/raw/raw7
# OCR
chown root:oinstall /dev/raw/raw1
chown root:oinstall /dev/raw/raw2
chmod 660 /dev/raw/raw1
chmod 660 /dev/raw/raw2
# Voting Disks
chown oracle:oinstall /dev/raw/raw3
chown oracle:oinstall /dev/raw/raw4
chown oracle:oinstall /dev/raw/raw5
chmod 644 /dev/raw/raw3
chmod 644 /dev/raw/raw4
chmod 644 /dev/raw/raw5

3 Unsupported Products

The following products are not supported with Oracle Database 10g release 2 (10.2):

4 Support for 64-Bit JDBC

disable_cap_mlock = 1

6 ASMLib Package Requirements

Install oracleasm-support package version 2.0.0.1 or later to use ASMLib on Red Hat Enterprise Linux 4.0 Advanced Server or SUSE Linux Enterprise Server 9.

7 Network Attached Storage for RAC Databases

This section contains issues that apply to RAC databases on NAS devices.

The following note in section "Requirements for Using a File System for Oracle Clusterware" of Oracle Database Oracle Clusterware and Oracle Real Application Clusters Installation Guide for Linux is not true and should be ignored for all Database installations on Oracle Clusterware:

If you are using a shared file system on a NAS device to store a shared Oracle home directory for Oracle Clusterware for RAC, then you must use the same NAS device for Oracle Clusterware file storage.

8 Installation, Configuration, and Upgrade Issues

Review the following sections for information about issues that affect Oracle Database installation, configuration, and upgrade:

8.1 Upgrading Oracle Real Application Clusters Release 9.2

If you upgrade a 9.2 RAC environment to Oracle Database 10g release 2 or install Oracle Database 10g release 2 on a computer running 9.2 RAC, then install the mendatory patch for Oracle bug 4656840 on all the nodes before installing 10g release 2 Cluster Ready Services (CRS). Ensure that you run the rootpre.sh script when prompted by Oracle Installer.

8.2 Correction to "Configuring Kernel Parameters" in RAC Install

In the RAC installation book, in the table in the section "Configuring Kernel Parameters," the following parameters have incorrect names:

net.core.rmem_default
net.core.rmem_max
net.core.wmem_default
net.core.wmem_max

The correct parameter names are as follows:

rmem_default
rmem_max
wmem_default
wmem_max

This issue is tracked with Oracle bug 4586020.

8.3 Installing Enterprise Security Manager

To install Enterprise Security Manager (ESM), install Oracle Client and then select the Administrator installation type.

8.4 Upgrading to Oracle Clusterware 10.2

When upgrading from 10.1.x to 10.2, if the host name directory under the /etc/oracle/scls_scr directory includes the domain name, then the following error message is displayed when you run the rootupgrade.sh script and the Oracle Clusterware stack does not start:

A file or directory in the path name does not exist.
/etc/init.cssd[509]: /etc/oracle/scls_scr/host_name/root/cssrun: 0403-005
Cannot create the specified file.

Workaround: Move the directory /etc/oracle/scls_scr/hostname.domain_name to /etc/oracle/scls_scr/hostname and rerun the rootupgrade.sh script.

This issue is tracked with Oracle bug 4472284.

8.5 extjob Executable Required Directory Permissions

To enable the extjob executable to locate required libraries, the $ORACLE_HOME/lib directory and all of its parent directories must have execute permissions for group and other.

8.6 Modifying a Virtual IP Address Node Application

When modifying the name, IP address, or netmask of an existing virtual IP address (VIP) resource, use the following command:

srvctl modify nodeapps

and include the existing interfaces for the VIP in the -A argument. For example:

srvctl modify nodeapps -n mynode1 -A 100.200.300.40/255.255.255.0/eth0

This issue is tracked with Oracle bug 4500688.

9 Other Known Issues

The following sections contain information about issues related to Oracle Database 10g and associated products:

9.1 Building Pro*C Applications if PostgreSQL is Installed

If the postgresql-devel package is installed on the system, then you must add the following directory to the beginning of the sys_include parameter in the $ORACLE_HOME/precomp/admin/pcscfg.cfg file before building Pro*C applications:

$ORACLE_HOME/precomp/public

If you do not make this change, then you may encounter errors similar to the following when linking the applications:

/tmp/ccbXd7v6.o(.text+0xc0): In function `drop_tables': 
: undefined reference to `sqlca'

This issue is tracked with Oracle bug 3933309.

9.2 European Language Locale

If the system uses a European language, then you must not use the UTF-8 locale. For example, if the system uses German, set the LANG and LC_ALL environment variables to de_DE instead of de_DE.UTF-8.

This issue is tracked with Oracle bug 3957096.

9.3 Oracle Clusterware Files Issues

The following note applies if you are using Red Hat Enterprise Linux 4.0 and using raw devices to store the Oracle Cluster Registry (OCR) and the voting disk for Oracle Clusterware, or using raw devices for Automatic Storage Management (ASM) database files. For each raw device used for the purposes listed, you must add two entries in the /etc/rc.d/rc.local file after running the root.sh script following the installation of Oracle Clusterware.

For each OCR file, the entries should look as follows, where oinstall is the Oracle install group and /dev/raw/rawn is an individual device file:

chown root:oinstall /dev/raw/rawn
chmod 640 /dev/raw/rawn

For each voting disk file, the entries should look as follows, where oracle is the Oracle user, oinstall is the Oracle install group, and /dev/raw/rawn is an individual device file:

chown oracle:oinstall /dev/raw/rawn
chmod 644 /dev/raw/rawn

For each ASM file, the entries should look as follows, where oracle is the Oracle user, oinstall is the Oracle install group, and /dev/raw/rawn is an individual device file:

chown oracle:oinstall /dev/raw/rawn
chmod 660 /dev/raw/rawn

9.4 Cluster Verification Utility Issues

This section lists the issues with Cluster Verification Utility on Red Hat Enterprise Linux 4.0 and SUSE Linux Enterprise Server 9:

  • Cluster Verification Utility (CVU) does not support shared checks for raw disks used for Oracle Cluster File System version 2 on Red Hat Enterprise Linux 4.0 and SUSE Linux Enterprise Server 9.

  • Cluster Verification Utility (CVU) does not detect SMP-Kernel rpms for the hosts and displays the "Kernel check failed" message. In verbose mode, the status for kernel is dislpayed as "missing".

    This issue is tracked with Oracle bug 4685951.

  • The preinstallation stage verification checks for Oracle Clusterware and Oracle Real Applications Clusters and reports missing packages. Ignore the following missing packages and continue with the installation:

    compat-gcc-7.3-2.96.128
    compat-gcc-c++-7.3-2.96.128
    compat-libstdc++-7.3-2.96.128
    compat-libstdc++-devel-7.3-2.96.128
    

9.5 Removing Metrics for Wait Classes Removes Them Permanently

Do not remove the key values for the wait class metrics. Doing so removes them permanently and currently there is no easy way to recover them.

This issue is tracked with Oracle bug 4602952.

9.6 Patch for CRS Configuration with Voting Disk on Network Attached Storage

To resolve the CRS configuration issue when voting disk is on Network Attached Storage, you need to apply the patch tracked through Oracle bug 4697432.
