Module: ORADB-MIB
OID (symbolic): ORADB-MIB::oraDbSysTableScansShort

Description: the 'table scans (short tables)' parameter from v$sysstat
What is oraDbSysTableScansShort?
This counter reports the 'table scans (short tables)' statistic from v$sysstat, the number of full scans against small tables, which Oracle often favors over index access since the whole table fits easily in cache. A high count here is usually benign and not worth tuning.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.111.4.1.1.1.21 snmpwalk -v2c -c public <target> ORADB-MIB::oraDbSysTableScansShort
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.111.4.1.1.1.21.1 snmpget -v2c -c public <target> ORADB-MIB::oraDbSysTableScansShort.1
