Sizing and scalability considerations

To plan your BMC Digital Workplace deployment, use the recommendations in this topic.

BMC Digital Workplace server cluster

To calculate the size of the environment required for BMC Digital Workplace, BMC uses these factors:

  • Total number of users
  • Estimated concurrent connections (usually 10% of the total users)

BMC recommends that you have one BMC Digital Workplace server (with 4 GB and 2 CPUs) for 15,000 registered users, which includes an estimated 1,500 concurrent users. For each environment, consider one extra BMC Digital Workplace server to allow for rolling maintenance and handling of peak loads for events (such as a system outage).

To determine sizing for your environment, use the following formula:

(Total users X 10% / 1500) + 1 = Number of BMC Digital Workplace servers

For example, for 75,000 users, the formula would look like this:

(75000 users X 10% / 1500) + 1 = 5 + 1 = 6 BMC Digital Workplace servers

For the 19.08 release, the above formula applies up to total of 90,000 users.

  • 100 GB HDD

BMC Digital Workplace Catalog database

The application platform requires a database in one of the following configurations:

  • Oracle 11.2.04+
    • SID name 8-characters or fewer, case-insensitive
    • Service name supported in Oracle RAC environments linked through a Single Client Access Name service.
      For more information, see the following resources on the Oracle website:
      • Oracle Single Client Access Name  (PDF 610 KB)

Note

These sizing estimates should be used as a starting point. You should conduct benchmarks in your environment because sizing will vary depending on the specific workload mix, data volumes, and data composition.

BMC Digital Workplace Catalog scalability

See the note on sizing and scalability in Multi-user workload test results in the BMC Digital Workplace Advanced 19.05 documentation. Performance testing was performed for version 19.05.

High Availability for BMC Digital Workplace Catalog

BMC Digital Workplace Catalog

can be run in a cluster for high availability (HA) using a load balancer, but note that:

  • All BMC Digital Workplace Catalog servers in a cluster can provide catalog items to BMC Digital Workplace Catalog
    .
  • Only one BMC Digital Workplace Catalog server can be used to manage the service catalog.

For instructions on setting up a cluster, see Configuring BMC Digital Workplace Catalog for high availability.
