From the JMX console whenever I try to run startTarOptimization() or runDataStoreGarbageCollection(java.lang.Boolean delete) , it is throwing the below exception.

Can somebody throw some light on this. We are on AEM6.0 SP2.

Hi,

the effect of online compaction averages over a few days(not as immediate as offline compaction), so you will not see an effect straight away.

For offline compaction, you should have at least twice the size of your repository, so for a 72GB repository, 50GB free space would not have been enough. Personally I would have preferred a bit more than double the size, but then I'm quite cautious :)

Regards,

Opkar

If you are not using CRX2 with AEM6, then there is no need to run tarOptimization with AEM6, as Oak does not use tar files. The equivalent is TarMK Compaction
