Dear valued Oracle DBA community,

after enabling Oracle Autonomous auto indexing feature some months ago for testing purposes, I recently realized that since this time SYSAUX space usage is continously increasing. It is already consuming ~16GB space in a very small testing project with just some tables.


My Analysis:

SELECT  occupant_name, space_usage_kbytes/1048576 spaceused, schema_name FROM v$sysaux_occupants ORDER BY spaceused DESC;
"Item"		"SPACEUSED"		"Schema"
"SM/ADVISOR"	15.99029541015625	"SYS"
"SM/AWR"	1.9677734375		"SYS"
...


SELECT TASK_NAME, COUNT(*) CNT FROM DBA_ADVISOR_OBJECTS GROUP BY TASK_NAME ORDER BY CNT DESC;
"TASK_NAME"			"CNT"
"SYS_AUTO_INDEX_TASK"		1536028
"SYS_AI_VERIFY_TASK"		1314294
"SYS_AUTO_SPM_EVOLVE_TASK"	50
"ADDM:949429955_2_4612"		4
"ADDM:949429955_2_4577"		4
"ADDM:949429955_2_4620"		4
"ADDM:949429955_2_4925"		4
...

Howdy, Stranger!
