Ensure 'AUDIT_TRAIL' is not set to NONE

HighLevel 1Automatedoceanbase

Description

The audit_trail setting determines whether or not OceanBase's basic audit features are enabled. It can be set to OS(Operating System); DB; DB_EXTENDED; or DB, EXTENDED. The value should be set according to the needs of the organization. NONE means audit is disabled. The benchmark rates this recommendation Manual; the automated check covers its objective pass criterion. Oracle-mode tenant, using the benchmark query. Passes when audit_trail is OS, DB, DB_EXTENDED or DB,EXTENDED on every server. Runs obclient against an Oracle-mode tenant using the connection options in OB_ORA_CONN (default "-h127.0.0.1 -P2881 -uSYS@oracle"); supply the password via OB_ORA_CONN (-p...) or ~/.my.cnf.

How it is checked

Audit method: SQL query

sql_query

out=$(obclient ${OB_ORA_CONN:--h127.0.0.1 -P2881 -uSYS@oracle} -N -B -e "SELECT svr_ip, name, value FROM oceanbase.GV\$OB_PARAMETERS WHERE name = 'audit_trail'" 2>/dev/null) || exit 1; printf '%s\n' "$out" | awk -F'\t' 'NF >= 3 {n++; v = toupper($3); if (v != "OS" && v != "DB" && v != "DB_EXTENDED" && v != "DB,EXTENDED") b++} END {print (n > 0 && b == 0) ? "compliant" : "noncompliant"}'

Expected output: compliant

How it is fixed

Fix method: Guidance or infrastructure patch

ALTER SYSTEM SET AUDIT_TRAIL = 'DB_EXTENDED'; (or OS / DB / 'DB,EXTENDED' per policy).
