Manage data center resources more easily using a simplified, central ISPF interface

IBM® Operating System Environment Manager for z/OS® (OSEM for z/OS) is a dynamic exit manager and a set of optional, standard control exits for the OS/390 and z/OS environments. As a dynamic exit manager, it provides a consistent, easy-to-use interface to most exit points provided by IBM to enhance the OS/390 and z/OS environment.

OSEM for z/OS offers data centers improved systems manageability. Driven by an easy-to-use ISPF interface, this solution makes it easier for you to manage your data center resources and control how they are used. OSEM offers a methodology and interface that enables you to manage your data center environment and ensure 24/7 availability as an administrative task, rather than a technical programming issue.

Features

• **Job routing and job classing controls: **With this powerful function, you can have job routing between CPUs based on defined resource names (subsystems like IBM® DB2® or IMS™) and their availability (up or down). You can manage resource availability on each system running IBM Operating System Environment Manager job routing and you can control the routing with JECL statements in the job or by assigning routing control information through the ISPF interface.
• **Dataset name conflict resolution: **This function prevents jobs from being selected until all needed datasets are available.
• **Job limiting controls: **Using the End User Computing Job Scheduling and Limiting options, you can limit the number of jobs that a user can be running concurrently.
• **Catalog account controls: **This function can be used to place up to 32 bytes of JOB or STEP accounting information into the catalog record for a newly created VSAM dataset or SMS-managed non-VSAM dataset. Additionally, the user ID of the job is placed into the Owner field of the catalog record. Neither of these fields is overridden if the information has already been provided.
• **Dynamic STEPLIB: **This function helps you migrate to LE/370 and any new version of most program products such as FILE/AID, SAS and others. You can modify or replace existing STEPLIB DD statements or add a new STEPLIB DD based on job class, job name, user ID, step name or program name.
• **Estimated cost: **Use this function to calculate an approximate charge for running each step of a job and an approximate total cost of running the job.
• **TIME controls: **Use this function to enforce CPU time limitations. Extend CPU time, JOB wait time and TSO wait time. Control, by job class, the insertion of a missing time parameter, overriding the time specified on the job card. Cancel the job if the job time is greater than the JES2 time value.

Benefits

• **Manage your data center: **Offers a methodology and interface to manage your data center environment and ensure 24/7 availability.
• **Maximize return on investment: **Get the most out of z/OS technologies thanks to improved system throughput and service levels and reduced costs.
• **Dynamic operating environment: **One that is easy for both technical and operations staff to use.
