Oracle Automatic Storage Management Cluster File System and Oracle Automatic Storage Management Dynamic Volume Manager are supported only on Oracle Enterprise Linux 5.0 and Red Hat Enterprise Linux 5.0 on Linux x86 and Linux x86-64.
Oracle Automatic Storage Management Cluster File System and Oracle Automatic Storage Management Dynamic Volume Manager are not supported on Linux Itanium, Linux on POWER, and IBM zSeries Based Linux.
Although Oracle Automatic Storage Management Dynamic Volume Manager supports raw disks in Oracle Automatic Storage Management disk groups, Oracle Automatic Storage Management Dynamic Volume Manager device special files created through raw(8) are not supported; Oracle Automatic Storage Management Dynamic Volume Manager only supports block device special files.
A single Oracle Database Client can request only a specific SCAN listener to connect to a database using SCAN and easy connect method. As a result, load balancing by the DNS round-robin is not available.
Connect to a database using the following configuration, specifying
LOAD_BALANCE=on, in the
ORCL = (DESCRIPTION = (LOAD_BALANCE=on) (ADDRESS = (PROTOCOL = TCP)(HOST = stscan1)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = srv.world) ) )
This issue is tracked with Oracle bug 8256753.
When upgrading from Oracle Database release 10.1.0.5 on Linux x86-64, the following errors may occur in the Database Upgrade Assistant:
ERROR at line 1:
ORA-00604: error occurred at recursive SQL level 3
ORA-00060: deadlock detected while waiting for resource
Workaround: Complete the following steps before upgrading to avoid the errors:
Before starting the release 11.2 upgrade, purge the
dba_recyclebin through SQL*Plus using the following command:
SQLPLUS> purge dba_recyclebin;
Disable the recycle bin using the following command:
ALTER SYSTEM set "_recyclebin"=FALSE;
Perform the upgrade.
Enable recycle bin after the release 11.2 upgrade using the following command:
ALTER SESSION SET recyclebin=ON;
This issue is tracked with Oracle bug 8475185.
While upgrading Oracle Clusterware of a previous release to Oracle Grid Infrastructure 11g Release 2 (184.108.40.206.0), Cluster Verification Utility (CVU) may fail if the permission and ownership on the raw devices configured with Oracle Cluster Registry and Voting Disks are incorrect.
Check CVU's output in the installation log file and fix the permissions and ownership on the raw devices. Then, click Retry to run CVU again.
This issue is tracked with Oracle bug 8737732.
When Oracle Database is installed on a Linux environment configured with Oracle VM, Oracle Universal Installer may show package check failures, and the RPM command returns the following error:
# rpm Floating point exception
Upgrade the RPM package to 220.127.116.11 or later.
This issue is tracked with Oracle bug 8626425.
The C++ XDK demos and Pro*C++ Static demos fail to link with the
-lstdc++ library giving the following error on Linux x86-64 with SUSE Linux Enterprise Server 10, SUSE Linux Enterprise Server 11, and Red Hat Enterprise Linux 5:

This issue is tracked with Oracle bug 8742500.
The following section contains information about issues related to Oracle Database 11g and associated products:
On Linux systems, if the operating system
/dev/shm mount size is too small for the Oracle system global area (SGA) and program global area (PGA), then you encounter the following error:
ORA-00845: MEMORY_TARGET not supported on this system.
The cause of this error is an insufficient
/dev/shm allocation. The total memory size of the SGA and PGA, which sets the initialization parameter
MEMORY_MAX_TARGET, cannot be greater than the shared memory file system (
/dev/shm) on your operating system.
Automatic Memory Management (AMM) has been updated in Oracle ASM 11g Release 2. It manages both the SGA and PGA together. It is managed by the Memory Manager Process (MMAN). In this release, note the following changes to AMM:
MEMORY_TARGET instead of
MEMORY_MAX_TARGET instead of
SGA_MAX_SIZE (defaults to
It uses memory allocated by
If the value of
max_target is set to a value greater than the allocation for the
/dev/shm size, then you may encounter the error ORA-00845: MEMORY_TARGET not supported on this system.
Note:An ORA-00845 error can also occur if
/dev/shmis not properly mounted. To rule out this possibility, run the command
df -kto ensure that
/dev/shmis mounted. For example:
$ df -k Filesystem 1K-blocks Used Available Use% Mounted on shmfs 6291456 832356 5459100 14% /dev/shm
/dev/shm mountpoint size.
# mount -t tmpfs shmfs -o size=7g /dev/shm
To make this change persistent across system restarts, add an entry in
/etc/fstab similar to the following:
shmfs /dev/shm tmpfs size=7g 0
