Oracle-labs Alternatives

oracle-labs reviews and mentions

• Oracle Patching, Demystified: CPU, RU, RUR — and What Changed in 2026
  1 project | dev.to | 8 Jul 2026

  Practice reading patch state. The no-Docker patching forensics lab hands you six real opatch lspatches / DBA_REGISTRY_SQLPATCH transcripts to diagnose — the datapatch gap above, a stale RU, a RAC node mismatch, a WITH ERRORS status, and the "apply the RUR" trap — with a grade.sh self-check. Just text and bash; no database required.

• ORA-00060 Deadlock: Find It, Fix It, Prevent It
  1 project | dev.to | 8 Jul 2026

  Want to see one for real? The deadlock lab induces an actual ORA-00060 on Oracle Database Free — two sessions lock the same two rows in opposite order — and prints the deadlock graph straight from the trace. Then a fixed drill runs the same workload in a consistent order so the deadlock never forms. One command each; no Diagnostics Pack.

• The Oracle HA Decision Tree: RAC vs Data Guard vs Both
  1 project | dev.to | 8 Jun 2026

  The full lab — the docker compose file, the run.sh driver, every drill script, and the optional Enterprise Edition Data Guard module — is the ha/ lab in github.com/pyaroslav/oracle-labs. Clone it, run it, break things on purpose. (No spare RAM on your laptop? The repo includes a guide to run the whole thing free on an OCI Always Free cloud VM.) Discovering that your runbook references a decommissioned host is a great thing to learn in a lab on a Tuesday afternoon — and a terrible thing to learn at 2am.
