Content Hosting, Resource Conversion : SAK-????

  • From the 2-5-x installation guide: 
    Moving from 2.4 to 2.5 requires adding several columns to the database tables used by the Content Hosting Service
(the service used by the Resources tool, Dropbox, filepicker and webDav). The conversion scripts contain DDL
statements to accomplish those changes. The new columns enable a switch from XML serialization to "binary-entity" 
serialization, which is faster and requires less memory. They also enable improved performance of quota calculations. 
You can get the benefits of binary-entity serialization without running the conversion utility, but you will never get 
the quota-calculation improvements without doing the full conversion.

There are two start up modes:

1. Dual mode - if the code detects the binary entity upon start up, it will run in dual mode. This means it will be 
capable of reading xml but will only writing to binary. This would give you the benefits of binary-entity serialization 
without running the conversion utility, but you will never get the quota-calculation improvements without doing the full conversion.

2. Binary only - The system will only reads and write binary and occurs only after a full database migration. Only 
once this is done, will a system be able to fully realize all the performance enhancements that binary entity serialization 
offers.  This occurs upon start up when it's detected that all of the xml fields are null.

There are two methods to get a fully database conversion.

1. Run the conversion utility which can be run on a live system.  Systems running oracle with large amounts should not attempt this right now.
2. Run the conversion upon start up. This is only recommended for implementations with smaller datasets.
