OSCAR IT support for Ontario practices.
OSCAR is one of the most widely used Canadian EMRs and one of the most flexible. The trade-off is that the underlying Linux, MySQL, Tomcat, and Java stack needs a team who actually knows it.
What slows OSCAR clinics down.
OSCAR is slow and the server is fine
Usually MySQL: missing indexes after years of data growth, slow queries in custom forms, or table fragmentation. We profile the database, find the bottleneck, and fix it without breaking anything clinical.
HRM, OLIS, or lab feeds stopped flowing
An eHealth Ontario certificate expired, a network rule changed, or the integration agent crashed. We chase down which link in the chain is broken and get the feed restored.
Disk on the OSCAR server is filling up
Document attachments, lab PDFs, and database logs all grow. We separate user data from system files, expand storage cleanly, and put monitoring in place so the next warning comes before the outage.
Nobody is sure if the backup actually works
We do a real restore into a separate environment, validate that a recent date can be loaded, and document what good looks like. That document becomes your evidence for insurance and your audit response.
Where Medibyte fits.
If the clinic runs self-hosted OSCAR, the clinic owns the server, the database, the backups, and the security. Medibyte runs that stack day-to-day, from operating system patches to OSCAR upgrades to integration certificates.
If the clinic is on OSCAR Pro through WELL Health, the application and database live with the host. The workstations, network, scanners, printers, Microsoft 365, backups of local data, and security around the connection are still the clinic's responsibility, and that is what we handle.

OSCAR EMR questions.
OSCAR is the open-source EMR maintained out of McMaster and used by many Canadian clinics on self-hosted Linux servers. OSCAR Pro is the commercial distribution operated by WELL Health, with hosting, support, and a managed billing layer included. Both share the same underlying codebase but differ on how the clinic gets support, who hosts the database, and which add-ons are available.
Yes. Self-hosted OSCAR runs on a Linux server inside the clinic or in a Canadian data centre. The clinic is responsible for the server, the database, the backups, and the security. Medibyte sets up and maintains self-hosted OSCAR environments, including verified backups, restore testing, and version upgrades.
The most common issues are MySQL database performance drift over time, disk space running out on the server, backups that have not been verified by an actual restore, and Java or Tomcat configuration problems after a software upgrade. None of these are clinical issues but they all stop the clinic from working until they are sorted.
Yes. OSCAR version upgrades are planned in a test environment first, validated against a current database copy, and rolled out with a documented rollback. The clinic gets a window where the old version is preserved so a rollback is possible if anything turns up after go-live.
OSCAR running slowly? Backup never tested?
