These results are quite poor. While writing this blog over the course of a few days, I have seen the round trip latency for this database vary from 25-500 ms. If this were a real production database rather than a throw away test database, it would be a good time to call in a network engineer. Now that we know the db ping test is fairly accurate, we can trust the results when used with an ATP database.

There is extra overhead for the database ping as compared to the ping utility, so it would be expected to take a more time. Just how much more time seems to vary with internet performance, as the remote databases are accessed via the internet. Multiple Row Set Ping If the extra time is due to database overhead, we should be able to devise a test that minimizes the database overhead. One way to do this is to use a single SELECT statement that returns many rows, so that only 1 SQL execution is required. Craft the SQL so that each row requires an entire TCP packet. Then get the total time required to retrieve the rows, and calculate the average latency. The following SQL was used: select systimestamp at local as ping_timestamp, rpad(''X'',1500-35-28,''X'') as filler from dual@dblink_name connect by level The standard TCP packet size is 1500 bytes, the length of `systimestamp at local` is 35, and the ICMP header is 28 bytes (on Linux anyway). When this new test is run, as the number of packets increases, the average time per row should be close to the times seen by using the ‘ping’ utility. This script was used to do that: ping-remote-db-multirow.sql Results of the multirow db-ping test: $ echo exit | sql -S -L jkstill/XXX@orcl/pdb1 @ping-remote-db-multirow.sqlLocal Seconds Begin: 1641644528.779681Local Seconds End: 1641644528.849177Round Trip: 0.069496==============================Local Seconds Begin: 1641644528.849205Local Seconds End: 1641644529.350788Round Trip: 0.501583==============================Local Seconds Begin: 1641644529.350817Local Seconds End: 1641644530.000492Round Trip: 0.649675==============================Local Seconds Begin: 1641644530.000530Local Seconds End: 1641644530.042419Round Trip: 0.041889==============================Local Seconds Begin: 1641644530.042447Local Seconds End: 1641644530.146593Round Trip: 0.104146==============================Local Seconds Begin: 1641644530.146621Local Seconds End: 1641644530.264522Round Trip: 0.117901==============================Local Seconds Begin: 1641644530.264549Local Seconds End: 1641644530.625663Round Trip: 0.361114==============================Local Seconds Begin:

TRIP Database – Free Access – Trip Database Blog

Whenever you import a database into UModel as shown in Importing SQL Databases into UModel, your project becomes bound with the database, and you can synchronize elements either from the database into the model, or vice versa.If you want to synchronize only from the database into the model, there is no need for any extra configuration—UModel takes care of all required mappings behind the curtains. For example, after each synchronization, new database tables will become new classes in the model, changed database column definitions will be updated in the model, and so on. All your database diagrams will also be updated automatically to reflect this.However, if you make changes to the model and want to synchronize them back into the database, some additional configuration might be necessary in the UModel project. This configuration may also be necessary if you want to prevent the project (or certain tables) from synchronizing with the database.A synchronization can either merge or overwrite changes—you can always configure this by running the menu command Project | Synchronization Settings.Note:Some database kinds do not allow changing the database structure by virtue of their design. For example, renaming tables and columns is not supported by Microsoft Access databases. Likewise, renaming columns is not supported in SQLite. Therefore, such changes in the model will not trigger a database update, and UModel may display warnings in the Messages window.Round-trip engineering for databases is very similar to round-trip engineering for program code—it revolves around a component in the "Component View" package that.
