I was looking at Oracle doc 169706.1 for swap space on AIX, and I saw this note for 11.2.0.2: Between 1GB and 2GB then 1.5 times RAM Between 2GB and 16 GB then match RAM More than 16 GB then 16GB RAM In prior versions, it says If RAM = 1024MB to 2048Mb then 1.5 times RAM elseif RAM > 2048MB and < 8192MB then match RAM else RAM > 8192MB then .75 times RAM Since 10.2 I have generally recommended that swap space equal RAM on Unix based OS versions. (twice RAM on SUN-SPARC with ism). What are other peoples experience/recommendations? -- Andrew W.
