Of course the problem was with my code: I've written the (temp) cursor handle to dataArr, not the address of it! Although this has nothing to do with allocation, but convinced me to clean up my code, as that has the error. Re-read the available documentation, and the last line of Table 5-1 at http://docs.oracle.com/cd/B12037_01/appdev.101/b10779/oci05bnd.htm#438183 said I need to write the address of the *OCIStmt, and I wrote only *OCIStmt, not **OCIStmt... I've tried, and it works now!
