TMA-TDSQL-1.9

Ensure Appropriate System Resource Limits Are Configured

MittelStufe 1Automatisierttdsql

Beschreibung

Operating system resource limits (ulimits) should be properly configured for TDSQL processes, particularly the number of open file descriptors, maximum processes, and memory locking. Passes when /etc/security/limits.conf or limits.d sets hard nofile and nproc limits of at least 65535 for the tdsql user (the benchmark baseline). For systemd-managed components also confirm LimitNOFILE/LimitNPROC in the unit.

So wird geprüft

Prüfmethode: Shell-Befehl

shell

out=$(cat /etc/security/limits.conf /etc/security/limits.d/*.conf 2>/dev/null) || exit 1; printf '%s\n' "$out" | awk '$1 == "tdsql" && $2 == "hard" && $3 == "nofile" && ($4 == "unlimited" || $4 + 0 >= 65535) {f++} $1 == "tdsql" && $2 == "hard" && $3 == "nproc" && ($4 == "unlimited" || $4 + 0 >= 65535) {p++} END {print (f && p) ? "compliant" : "noncompliant"}'

Erwartete Ausgabe: compliant

So wird behoben

Behebungsmethode: Anleitung oder Infrastruktur-Patch

Add to /etc/security/limits.conf: tdsql soft nofile 65535; tdsql hard nofile 65535; tdsql soft nproc 65535; tdsql hard nproc 65535; tdsql soft memlock unlimited; tdsql hard memlock unlimited; then restart the components.
