This article details a two‑day troubleshooting process that identified missing SSL certificates and TLS configuration as the cause of Jenkins Artifactory plugin upload failures on AIX, and explains how setting the SSL_CERT_FILE environment variable and a JVM option restored successful artifact uploads.
This article outlines the origins of UNIX, its trademark evolution, major branches such as BSD, System V, and the various commercial UNIX-like systems—including Mac OS X, AIX, Solaris, HP‑UX, IRIX, Xenix, A/UX—and the rise of Linux and its many distributions.
When a critical Oracle 10g database on AIX spikes to 100% CPU, this detailed case study walks through emergency actions, AWR analysis, hidden bottlenecks, and practical tuning steps that reduced CPU usage by half and restored system stability.
The article compiles thirteen post‑mortem case studies of severe system outages—from AIX NTP misconfiguration and backup appliance driver issues to PowerHA node ID conflicts and hardware failures—detailing symptoms, root‑cause analysis, and practical remediation steps for each incident.
An Oracle 11g instance on AIX 6100‑07 unexpectedly restarted due to a memory‑management bug triggered by the numperm_global=1 setting, which caused massive paging despite ample free memory; the article analyzes logs, OS metrics, and offers four remediation options including parameter changes and OS patches.
This article explains IBM PowerHA (formerly HACMP) for AIX, covering its architecture, heartbeat‑based failover mechanisms, topology and resource components, dual‑active HyperSwap solutions, and the role of the HMC management console in providing enterprise‑grade high availability.
In this detailed DBA case study, the speaker explains how improper settings of Oracle's parallel execution parameters on an AIX‑based 10gR2 database led to process saturation, undo‑related wait events, and temporary connection issues, and describes the step‑by‑step diagnosis, parameter adjustments, and lessons learned for future tuning.
An Oracle RAC 11g installation on AIX failed intermittent queries with ORA‑04030 errors, and a deep dive revealed that missing shell limits for the grid user capped process memory at 128 MB, causing PGA allocation failures despite ample system resources.
Expert DBAs discuss critical Oracle 11.2.0.4 parameters to watch before production, covering generic, performance, deprecated, and OS‑level settings for AIX and Linux, with concrete examples such as shared pool sub‑pools, mutex tuning, cursor thresholds, and real‑world incidents like streams_pool_size misconfiguration.
