• Welcome to Configuring Red Hat Linux for Health Connect

    This job aid references chapters of the documentation for HealthShare Health Connect as an HL7 integration engine and provides links as appropriate to enable you to install HealthShare Health Connect on Red Hat Linux.

    • There should be a review of all requirements prior to configuring your environment. While InterSystems typically provides best practice configurations, on occasion, we are asked to quote or provide configurations that allow for an apples to apples comparison with systems that are not enterprise grade and do not provide such features as mirroring. In these circumstances you will want to confirm your configuration is not decided by such a request, but rather what is in the best interest of your facility. If you believe this to be the case for your configuration please request a new configuration, that follows InterSystems best practices guidelines, be provided by your assigned sales team.

    • In Step 8, you determined routine and database (or global) buffer values. Let’s use as an example a database buffer of 8 GB and routine buffer of .5 GB. We will use these to calculate settings appropriately.
      • You will not be using Kerberos Authentication, so no need to worry about that section in the documentation. 
      • It is recommended that you set SHMMAX equal to the size of: ((database buffer) +(routine buffer) +( 4 MB)).
      • Huge Pages default to 2 MB in size. For example, if you had 9 GB of shared memory, you would want about 5000 of them allocated, since it is slightly more than the 9 GB of shared memory allocated as Huge Pages.
      • Since we will be using Huge Pages, you do not need to consider the "Locked In Memory” chapter of the RHL notes.
      • We should follow the advice for Dirty Page Cleanup per documentation.
      • To ensure sufficient swap space, it is recommended to allocate at least 10 GB of swap space.
