Hi,

if I understand you want to take a different library (path) form the embedded one.
1) change SHLIB_PATH so your new library is on the path.
2) chatr +s enable +b disable
This will enable the search on SHLIB_PATH 1st.

But this is by no way a guarantee it will work properly. Upgrades between major releases, and sometimes even between minor releases, will lead to (binary) incompatibilities.

Sometimes the application will not work at all with the new DB environment, but this is still better than when it /appears/ to work fine, but in fact ruins your valuable data in the background.

Personally I'd not advice *anyone* to walk this road, and /IF/ you decide top go there anyway, be sure to

1. Have a good (and tested) backup
2. Run as many tests as possible before going life
3. Run the edge cases

Enjoy, Have FUN! H.Merijn [ being bitten by far too many incompatibilities in version land in the past ]

As Merijn metioned it, because you change the libraries you require the full UAT cycle.

I've done it in the past not for new libraries but for a new location for the libraries.
