  • Requires disaster recovery
  • Entail a large volume of stored data
  • Demand rapid response time for transaction or analytical processing

The z Systems platform consists of:

  • 10 GB network connections
  • No single point of failure
  • Parallel Sysplex design for redundancy and reliability
Mainframe Computer

Highlights

  • No need to purchase or manage servers, system software, storage or network equipment
  • Customers focus on supporting their application product, not the hardware or operating system
  • 24/7 Service Desk support

Infrastructure Capacity

We review workload growth monthly to determine capacity needs and annually increase the capacity of CPU/DASD/VTS and network components to keep pace with increases in workload demand.

  • Conduct system level performance tuning as necessary.
  • Provide performance reporting regarding processor utilization, memory consumption, and disk utilization.
  • Monitor system throughput, usage, and capacity.

Support of z Systems Application, Database, and Software

We have implemented industry best practices in support of the z Systems platform to ensure that the operating system and third-party software are at vendor supported versions. The application, database and software support includes, but is not limited to, installation, testing, maintenance, software licenses (keys), user exits, local mods, procurement, and migration to production.

Support of z Systems Infrastructure OS and Hardware

We have developed industry best practices in support of the z Systems platform to ensure that any hardware components (CPU, DASD, VTS, network components, etc.) are maintained via warranty, or are on an annual hardware refresh cycle. The OS and hardware support includes, but is not limited to the installation, testing, maintenance, software licenses (keys), user exits, local mods, procurement, and migration to production.

Database

We offer a number of database management system (DBMS) technologies.

  • ADABAS
  • Db2 – We support IBM’s relational database management system – Db2 – and its associated products. Db2 Data Sharing Groups are available and IBM’s Db2 Analytics Accelerator (IDAA). IDAA hardware and software allows for data analytics, data reporting and data warehouse functionality for application processes requiring these features. Access to the Db2 Tools and Utilities is currently available via 3270 emulation and will be available via web browsers in the future. The current version of Db2 includes REST services. Db2 REST services enable your web, mobile, and cloud applications to interact with Db2 data through a set of scalable RESTful Application Program Interfaces (API). These API’s are fully integrated into the Db2 distributed data facility (DDF).  The APIs can create, discover, execute, and manage user-defined services in Db2.

Middleware

We provide a number of middleware technologies, including:

Printing

We offer multiple printing options:

  • Printing on a printed page, on impact printers or laser printers
  • Printing on a printed form
Go-Online

Go-Online provides Customers an efficient and secure alternative to view and manage output via a web browser on a desktop, mobile devics, etc. Customers can immediately access documents/reports stored in their z System repository utilizing Output Management Web Viewer (OMWV), CA-View and CA-Deliver. This provides an economical and “green” alternative to printed reports.

For additional information, FAQs and training demonstrations visit the Go-Online training webpage.

Other Services

  • Stand-by Services – We are available, upon a Customer’s advance request, to provide standby support. In some cases, stand-by services may be billable to the Customer.
  • Consulting Services – We provide customer training on specific technical items.
  • Vendor Liaison Services – We can communicate with vendors, as requested, to ask questions on behalf of a Customer.

Data Backup

Incremental backups are performed regularly on all data that resides in data center managed pools, i.e. all volumes except dedicated volumes. (Dedicated volumes are assigned and billed to a customer who is responsible for all storage management activities for that volume.) All backups are written to high capacity tapes.

Incremental Backups

Incremental Backups are performed by a software product called Hierarchical Storage Manager (HSM) and are done at the dataset level. These are logical backups of the datasets that are newly created or have changed since they were last backed up. All SMS datasets in the general pools are backed up by HSM.

Frequency – Datasets are backed up late evening/early morning after they are created or modified, every day of the week at Gold Camp.

Retention – The seven (7) latest versions of a dataset are retained for a maximum of 30 days. If a dataset is deleted, the last backup copy is retained for 90 days.

Off-site Replication- All backups are replicated off-site using Virtual Tape Server (VTS) for the defined retention period.

Exceptions – Datasets in use at the time of the backups are skipped and NOT backed up.

Restore – Customers can do their own restores via the HRECOVER panel. If additional help is needed, Customers can submit an incident ticket using the CDT Service Request tool, or contact the Service Desk at (916) 464-4311.

Customer Responsibilities

  • More frequent backups, if required, of critical data stored on DASD volumes.
  • Creating long-term (retention period) backups, if needed, of data stored on DASD volumes.
  • All backups of data stored on Customer dedicated volumes.
  • Datasets that are in use during the CDT backup window.
  • Database files.

Full Volume Backups

Full Volume Backups are performed by a software product called FDR. All system volumes are backed up on a weekly basis and kept for 30 days. The Service Continuity Mainframe Services (SCMS) offering enables us to provide Disaster Recovery for the z Systems platform and for Customers’ whose systems are hosted at one of the two CDT campuses (Rancho Cordova & Vacaville).
