As far as I can understand, regardless of Oracle releases, there are only 2 versions of OCI, OCI7 and OCI8. Someone to aprove or correct me.
So this means that since we have Oracle 11.2g I can activate client caching on the existing OCI ? Sounds strange, if Client caching is a new functionality, wont it require a new function call or something?
Omg you moved it in here, with 1 reply every 2 weeks! :'( Its dead
Two weeks later If you link with the Oracle 11.2 OCI libraries you will be able to use the Oracle 11.2 features. It's the library version, not the "OCI version" that counts for that. The "OCI version" defines the core API but not the full feature set.
Yes but Isn't the use of the 2 new functions PrepareStatement2 FetchRows2 mandatory ?
I ve red so I think in oracle manuals. And I tried altering an example using these 2 functions with the oolder ones but I ve failed (old dont support scrollable cursors e.g. dont know if its mandatory for client caching)
Ok waiting reply next 2 weeks
I haven't actually used the client result cache. PrepareStatement2 & FetchRows2 are mandatory for the client STATEMENT cache, not the client RESULT cache. I've used statement caching but not client result caching. If your application prepares statments and then re-uses the statement handles, it can still use result caching. If it prepares the statement fresh each time it executes it, then it will need to either change to reuse handles, or use PrepareStatement2 & FetchRows2 to get OCI to cache the handles.
Was your program written with calls to olog(), oparse(), oexec() etc. ? Those were made obsolete in the late 1990's, but it is still possible that client result caching will work with them if you enable it via ALTER SESSION SET
RESULT_CACHE_MODE,/*+ result_cache */ hints, ALTER TABLE ... RESULT_CACHE statements if it re-uses handles in the correct (efficient) way.
Hmm so you havent actually used it. Because OCI Manual says that these 2 new functions are for providing Client Result Caching.
So probably they re needed fro client caching.
In that case you would nee both the libraries and latest oci to use these latest functions probably
(Sorry for the late reply, this zombie place rate its affecting me )
