How To Get A Job At Oracle – By defining new job types, you can extend the utility and flexibility of the Enterprise Manager job system. Adding new job types also allows you to improve corrective actions. This chapter assumes that you are already familiar with the Enterprise Manager job system.
Enterprise Manager allows you to define jobs of various types that can be executed using the Enterprise Manager job system, thus expanding the number and complexity of tasks you can automate.
How To Get A Job At Oracle
By definition, a job type is a specific category of jobs that perform a well-defined unit of work. A job type is uniquely identified by a string. For example, OSCommand can be a job type that runs a remote command. You define a job type using an XML specification that defines the steps in a job, the work (order) that each step performs, and the relationships between the steps.

An Enterprise Manager job consists of a set of steps, and each step runs a command or script. The job type defines how the steps are assembled. For example, which steps run in series, which run in parallel, order of steps and dependencies. You can express a job type, steps, and commands in XML (for more information, see “Specifying a new job type in XML”). The job system then constructs an execution plan from the XML specification that allows it to run the steps in the specified order.
A new job type is specified in the XML. The job type specification provides the following information to the job system:
The XML job type specification is then added to a metadata plug-in archive. After the metadata plug-in is added to Enterprise Manager, the job system has enough information to schedule the job steps, as well as what to run in each step.

A job type can have one of the following categories, depending on how it performs tasks on the targets to which it is applied:
An agent-bound job type is one whose jobs cannot be executed unless the Management Agent of one or more targets in the target list is running and responding. A job type that falls into this category must declare itself agent bound by setting the agentBound attribute of the jobType XML tag to true.
If a job type is agent bound, then the job system does not schedule any execution if one or more management agents corresponding to the targets in the job execution target list do not respond. The job (and all its scheduled steps) is set to a special state called Suspended/Agent Stopped. The job is kept in this state until the Enterprise Manager repository tier detects that the Management Agent has restarted.
At this point, the job and its steps are set back to the scheduled state and the job can run. By declaring their job types to be agent bound, a job type writer can ensure that the job system will not schedule the job when it has detected that the management agent is down.

If an agent-bound job has multiple targets in its target list, then it is marked as Suspended even if one of the management agents fails.
An example of an agent-bound job type is the OSCommand job type, which executes an OSCommand using the Management Agent of a specified target. However, not all types of jobs are related to the agent. For example, a job type that executes SQL in the Management Repository is not agent bound.
Enterprise Manager has a heartbeat mechanism that allows the warehouse tier to quickly determine when a remote management agent has failed. After a Management Agent is marked as Inactive, all job executions related to the Agent that have this Management Agent in their target list are marked Suspended/Agent Down. However, there is still a possibility that the job system may try to submit some remote operations during the time that the Management Agent is down and the management archive detects this fact. In cases where the management agent cannot be reached and the step is executing, the step is reset to the SCHEDULED state and retried by the job system. The series of retries continues until the heartbeat mechanism marks the node as down, at which point the job is suspended.
When a job is marked as Suspended/Agent stopped, by default the job system keeps the job in that state until the Management Agent restarts. However, there is a parameter called grace period which, if defined, can override this behavior. The grace period is the maximum amount of time (in minutes) that a job can start running. If the job cannot start within this grace period, job execution is skipped for that schedule.

The only way to resume execution of a job in a Suspended/Agent Stopped state is for the management agents to come back. You cannot use the resume_execution() APIs to resume the job.
The unit of execution in a job is called a step. A step has a command, which determines what the step will do. Each command has a Java class, called a command executor, that implements the command. A command also has a set of parameters, which will be interpreted by the executor of the command.
Steps are grouped into sets called step sets. Step sets can contain steps or other step sets and can be classified into the following types:
The default algorithm by which the status of a stepset is calculated from the state of its steps can be changed by the job type, using the stepsetStatus attribute of a stepset. By setting stepsetStatus to the name (ID) of a step, stepset, or job contained within it, a stepset can indicate that the state of the stepset depends on the state of the specific step, stepset, or job named in the stepStatus attribute. This feature is useful if the author of a job type wants a set of steps to succeed even if certain steps within it fail.

An example is a step that runs as the final step in a set of steps in a job that sends job status emails to a list of administrators. The job status must be set to the status of the step (or steps) performing the job, not the status of the step that sent the email. Only steps that are executed unconditionally can be named in the stepsetStatus attribute. A step, set of steps, or job that is executed as a successOf or failureOf dependency cannot be named in the stepsetStatus attribute.
To pass job parameters to steps, enclose the parameter name in a placeholder (contained in two %) symbols. For example, %patchNo% represents the value of a parameter named patchNo. The job system overrides the value of this parameter when passed to a step’s command executor.
Substitutes can also be defined for vector parameters using the  notation. For example, the first value of a vector parameter named patchList is referenced as %patchList%, the second is %patchList%.
The job system provides a predefined set of placeholders that can be used. These are always prefixed by job_. The following substitutes are provided:

The above placeholders are not interpreted by the job system, but by the management agent. For example, when %emd_root% is used in remoteCommand parameters or ai args
A step consists of a status (indicates whether it succeeded, failed, or ended), an output (the step log), and an error message. If a step failed, the command executed by the step might indicate the error in the error message column. By default, the standard output and standard error of an asynchronous remote operation are set to the output of the step that requested the remote operation.
This section describes the available commands and their associated parameters. Targets of any type can be provided for the target name and target type parameters described in the following sections. The job system automatically identifies and contacts the management agent monitoring the specified targets.

Is the use of the credential that is understood by the command. For example, the Java code in the command makes a call for credentials with this string, while
The standard output generated by the executed command is stored by the job system as the result corresponding to this step.
In some cases, you may need to submit additional credentials for a remote operation. These credentials are called auxiliary credentials because they are used in addition to the host credentials required to connect to the Management Agent where the remote operation must be generated.
The processing of auxiliary credentials depends on the process that is generated at the Management Agent. The job system provides a mechanism to extract the column values of a credential into variables that can be used for substitution within the input parameter of the remote operation command (
