Paravirtualization delivers an efficient method by which to virtualize an environment. However, a clear disadvantage to paravirtualization is that the guest operating system must be modified to be virtualization-aware. In terms of Linux, it is now necessary to work with a different version of the operating system compared to the native environment. However, the modifications are minimal. Operating systems that are not open source cannot be paravirtualized, which means they cannot run under the Xen hypervisor in this way. Full virtualization or hardware-assisted virtualization is a method by which unmodified nonvirtualization aware operating systems can be run in an Oracle VM Server environment. With a Linux guest operating system, this means being able to run exactly the same version of the Linux kernel that would be run on the native platform. To do this requires a processor with virtualization technology features. Intel calls this technology Intel VT; for Oracle VM server on the x86 and x86-64 platform, the

Semaphores are used by Oracle for resource management. They serve as a post/wait mechanism by enqueues and writers for events, such as free buffer waits. Semaphores are used extensively by Oracle, and they are allocated to Oracle at instance start-up in sets by the Linux kernel. Processes use semaphores from the moment they attach to an Oracle instance waiting on semop() system calls. Semaphores are set with the sysctl command or in the /etc/sysctl.conf file. This behavior differs from that of other Unix operating systems, where the different values are often allocated individually. You can view the semaphore limits on your system with the command ipcs ls: [root@london1 ~]# ipcs -ls ------ Semaphore Limits -------max number of arrays = 128 max semaphores per array = 250 max semaphores system wide = 32000 max ops per semop call = 100 semaphore max value = 32767 You use the kernel.sem parameter to control the number of semaphores on your system. The Oracle Validated RPM sets the value of kernel.sem to the following values: kernel.sem = 250 32000 100 142 This setting allocates values for the semmsl, semmns, semopm, and semmni parameters, respectively. Semaphores can be viewed with the operating system command ipcs ls .The semmsl parameter defines the total number of semaphores in a semaphore set. This parameter should be set to the Oracle Validated RPM value of 250. Setting semmsl should always be considered in terms of semmns because both parameters impact the same system resources.

The semmns parameter sets the total number of semaphores permitted in the Linux system, and 32000 is the recommended default high-range value. The previously discussed semmsl value sets the maximum number of semaphores per set, while semmni sets the maximum number of semaphore sets. This means that the overall number of semaphores that can be allocated will be the minimum value of semmns or semmsl, multiplied by the value of semmni. A default value of 32000 for semmns ensures that this value is used by the system for its total semaphore limit. The semopm parameter defines the maximum number of semaphore operations that can be performed by the semop() system call. In Linux, semop() can set multiple semaphores within a single system call. The recommended setting for this value is 100. The semmni parameter sets the maximum number of total semaphore sets defined, and it should have a minimum value of 128. Multiplying this value by a semmsl value of 250 precisely equals the semmns setting of 32000. Although the Oracle Validated RPM sets this value to 142, it is overridden by semmns. Unless an extremely large number of Oracle user connections are required on each node, the Oracle Validated RPM semaphore settings should be sufficient.

try { OracleConnection _connObj = new OracleConnection(); _connObj.ConnectionString = _connstring; _connObj.Open(); OracleGlobalization info = OracleGlobalization.GetClientInfo(); info.Territory = "Sweden"; info.Language = "Swedish"; OracleGlobalization.SetThreadInfo(info); _connObj.SetSessionInfo(info); OracleCommand _cmdObj = _connObj.CreateCommand(); _cmdObj.CommandText = "SELECT TO_CHAR(Price,'L99G999D99') PriceDefCurrency, TO_CHAR(Price,'U99G999D99') PriceDualCurrency, TO_CHAR(ExpiryDate, 'DL') ExpiryDate FROM Products WHERE ID='B1'"; OracleDataReader _reader = _cmdObj.ExecuteReader(); if (_reader.HasRows) { if (_reader.Read()) { String _priceDefCurrency = _reader.GetString (_reader.GetOrdinal("PriceDefCurrency")); String _priceDualCurrency = _reader.GetString (_reader.GetOrdinal("PriceDualCurrency")); String _expiryDate = _reader.GetString (_reader.GetOrdinal("ExpiryDate")); _result = _priceDefCurrency + "\n" + _priceDualCurrency + "\n" + _expiryDate; MessageBox.Show(_result); } } _reader.Dispose(); _cmdObj.Dispose(); _connObj.Dispose(); _reader.Close(); _connObj.Close(); _reader = null; _connObj = null; _cmdObj = null; } catch (Exception ex) { MessageBox.Show(ex.ToString()); } } If you run this code sample, you can see the message box shown Figure 6-14. That message box shows all the appropriately formatted data for Sweden.

To handle the exception yourself, you code two catch clauses:

Setting network parameters correctly is especially important in a RAC environment because of its reliance on a local high-performance network interconnect between the Oracle instances. The next section describes the kernel parameters modified by the Oracle Validated RPM.
