Hi Matt,

You are using the wrong syntax, this option I mentioned above is meant to be used only on Exadata platform.

You probably should use this (if you have the advanced compression licenses):

alter table t compress for all operations;

I just want to compress the entire table and I am getting ORA-64307. I am not even trying to compress a single column. I have used compression in 10G just fine, but using the new syntax in 11G is not working out so well.

Running: alter table compress for query high;

I want new data to be compress and my old 10G syntax does not accomplish that.

[...] from the field of what levels of compression are actually realistic. (Edit: Actually, it seems that hybrid columnar compression only works with Exadata, at least at this time.) But for now, we don’t have much to go on except Oracle’s [...]

[...] PPT: Data Warehousing with Oracle Database 11g Release 2 Filed under: Oracle Business Intelligence — H.Tonguç Yılmaz @ 8:10 am There are several exciting new features with 11.2 on BI topics: http://download.oracle.com/docs/cd/E11882_01/server.112/e10881/chapter1.htm#AREANO02555. It is sad to test columnar compression new feature and now to know that it is only available with Exadata: ORA-64307: hybrid columnar compression is only supported in tablespaces residing on Exadata storage [...]

I wonder how this will affect vendors like SAND Technology (www.sand.com)? It seems so many companies out there do not want to upgrade on Oracle due to costs, but an independent product like SAND could be a nice compromise…

Oracle’s is the third hybrid row/column storage scheme announced in the last month. It’s time for a taxonomy: http://dbmsmusings.blogspot.com/2009/09/tour-through-hybrid-columnrow-oriented.html

I understand, Tanel. It is true data “is stored one column at a time.” That phrase doesn’t insinuate rows are totally out of the picture though. Picture, for instance, a hypothetical database implementation where rows have nothing in them except pointers to tablespaces where columns are stored on per partition basis and then sub-partitioned by range or something. I could refer to such a database as organizing the data in a columnar orientation but I still have rows. Now, this hypothetical is not aimed at describing what HCC does, but it is an easily understood example of a hybrid.
