color combination. The switches passed to xterm are for the font, color combination, scroll-back configuration, and title-bar definition. All of these can be specified in the user s configuration file. The -e switch to xterm defines what you want to have executed within the xterm window. In our case, it will be either an ssh, rlogin, or telnet connection to the remote machine.

You can map each Scheduler job class to a specific resource consumer group. A resource plan is assigned to a resource consumer group, and thus indirectly to each job class as well, by the Database Resource Manager. The active resource plan (as determined by the currently open window) will apportion resources to groups, giving different levels of resources to different jobs, based on their job class. The Scheduler works closely with the Database Resource Manager to ensure proper resource allocation to the jobs. The Scheduler will start a job only if there are enough resources to run it. Within each Scheduler window, you can have several jobs running, with varying degrees of priority. You can prioritize jobs at two levels class and job. The prioritization at the class level is based on the resources allocated to each resource consumer group by the currently active resource plan. For example, the FINANCE_JOBS class might rank higher than the ADMIN_JOBS class, based on the resource allocations dictated by its active resource plan. Within the FINANCE_JOBS and ADMIN_JOBS classes, there will be several individual jobs. Each of these jobs has a job priority, which can range from 1 to 5, with 1 being the highest priority. You can use the SET_ATTRIBUTES procedure to change the job priority of any job, as shown here: SQL> BEGIN dbms_scheduler.SET_ATTRIBUTE( NAME => 'test_job', ATTRIBUTE => 'job_priority', VALUE => 1); END; The default job priority for a job is 3, which you can verify with the following query: SQL> SELECT job_name, job_priority FROM dba_scheduler_jobs; JOB_NAME JOB_PRIORITY ------------------------------ --------------------ADV_SQLACCESS1523128 3 ADV_SQLACCESS5858921 3 GATHER_STATS_JOB 3 PURGE_LOG 3

When you have more than one job within the same class scheduled for the same time, the job_priority of the individual jobs determines which job starts first.

The HelloWorld4 application was written to explain both kinds of transitions It is extremely helpful to have both these options and to control in a very fine-grained way when a transition from managed code to unmanaged code, or from unmanaged code to managed code, takes place In real-world applications, it is important to avoid these transitions, because method calls with these transitions are slower Reducing these transitions is key to avoiding performance penalties in C++/CLI To detect performance problems, it can be very important to identify transitions between managed and unmanaged code Reducing performance penalties is often done by introducing new functions that replace a high number of managed/unmanaged transitions with just one 9 gives you detailed information about internals of managed/unmanaged transitions The code samples used so far have used the simplest possible method signature.

Since windows might have overlapping schedules, you may frequently have more than one window open at the same time, each with its own resource plan. At times like this, the Scheduler will close all windows except one, using certain rules of precedence. Here is how the precedence rules work: If two windows overlap, the window with the higher priority opens and the window with the lower priority closes. If two windows of the same priority overlap, the active window remains open. If you are at the end of a window and you have other windows defined for the same time period with the same priority, the window that has the highest percentage of time remaining will open.
