the system path c:\\private\\100012a5\\DBS_100065FF_Contacts.cdb

the system path c:\\private\\100012a5\\DBS_100065FF_Contacts.cdb

Then you would need to execute the deletion functions from a process having secure ID of 0x100012a5, othervise you actually would need to have AllFiles+TCB.

Hi,

If you just want to reset the db then a possible way is to open the database by the Symbian OS Database API (RDbs, RDbNamedDatabase), then clear all the db records, not tried but in theory it should requires only ReadUserData/WriteUserData capabilities.

There is an example in the following post shows how to use RDbNamedDatabase to read/write the db files managed by the database server (UID 0x100012a5).

provided that the process where the API is used has secure ID of 0x100012a5, then you do not need any capability, and if the proces does not have that specific SID, you still need AllFiles + TCB with those APIs as well.

Hi,

"No you didn't listen to me. I'm not asking anyone to read/write the file directly, actually the secure database files are managed by DBMS server (UID 0x100012a5) so it is absolute possible to access the database by Symbian OS DBMS API (client API like RDbs, RDbNamedDatabase, etc), the capabilities required are totally depends on the secure policies defined by the specific database. It just like you can use CRepository to access Central Repositories whose data files are stored in the private folder of the CenRep server (UID 0x10202be9)."

The words above are copied from the following thread:
