Features and benefits
Key features include:
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.
IBM Operating System Environment Manager provides numerous technology and business benefits:
Improved manageability with simplified standards enforcement, software upgrades and system and data center consolidation; enhanced storage management and the facilitation of accounting and charge back
Improved system throughput and service levels with automatic resource overrun handling, optimized resource availability, increased system availability and improved responsiveness
Reduced hardware costs with delayed CPU upgrades, reduction in the number of required tape devices, improved use of DASD and reduction in the number of required special devices
Reduced software licensing costs with a reduction in required software licenses and facilitated migration from JES3 to JES2
Reduced human resources costs with a reduction in effort for system upgrades and exit development and maintenance and increased automation of storage administration
