| A: | The advantages of UDB over SDB Plus: 1. Supports massive data. 2. Cross-platform data sharing. 3. Efficient way to read and write. 4. Employs technologies like double encryption to ensure data safety. 5. Supports cross-thread operations, but not multi-thread access. |
| Q: | Why is there information loss during the browsing and query on attribute information? |
| A: | The encoding of the Chinese characters storage has some modification for better performance in SuperMap Objects .NET SP2.

| Q: | I created an Oracle datasource in SuperMap Deskpro .NET 6R or 7C (7.0.0), then opens it in the version 7.1.2 or above, and then open it in the old version, it will not be opened. Why? |
| A: | There are two solutions which need to operate the tables in the database. The projection information is needed to be set again, please make a backup for it. Solution 1: update smdatasourceinfo set mprojectinfo = emptyblob() where dbmslob.getlength(smprojectinfo)>199; update smregister set smprojectinfo = emptyblob() where dbmslob.getlength (smprojectinfo)>199; update smimgregister set smprojectinfo = emptyblob() where dbmslob.getlength(smprojectinfo)>199; commit; This method may cause an error ORA-00997. There is solution 2. Solution 2: alter table smdatasourceinfo drop (smprojectinfo); alter table smdatasourceinfo add (smprojectinfo blob); alter table smregister drop (smprojectinfo); alter table smregister add (smprojectinfo blob); alter table smimgregister drop (smprojectinfo); alter table smimgregister add (smprojectinfo blob); At last, please set the projection. |
| Q: | When copying the network dataset, if first copy the sub dataset to a new UDB datasource, then copy the parent dataset, close the UDB datasource then open it again, the sub dataset is missing and the father dataset can’t be opened well. |

| Q: | My operation system is Win10 or Win8, and I can not open my workspace, datasource, etc. by dragging the corrsponding files into SuperMap iDesktop, what should I do? |
| A: | The reason is that SuperMap can not obtain the dragging message. Win8 and Win10 adopts the User Account Control feature, and dragging is a lower-privilege operation, however is an administrative-privilege application which means it can not receive the information from a lower-privilege one. Solution: Change the UAC privilege to make your operation system supports the dragging operation. The detail operation is: execute Tools\EnableLUA\EnableLUA.reg in your product package and then restart your computer. |

You can have a try to resolve the problem by following three solutions: 1. Upgrade your Oracle client to 11g or above. 2. Use a 64-bits Oracle client and a 64-bits iDesktop. 3. Move your iDesktop program to make its path without ”)“. |
