6.4 Remote Database Problems

If you are using a centralized database server instead of the default local database, you may encounter

problems with connecting to the database or encounter performance problems. This section covers the

most common issues encountered.

You should also review the Using a Remote Database topic, which covers basic information on TCP/IP

ports used for the remote database and the correct naming conventions for assigning a remote

database server.

6.4.1 Problems Connecting to the Remote Database

If you experience difficulties connecting to the remote database you wish to maintain, it is likely that

one or more of the following issues are affecting the connection.

The remote database identity is incorrect

If the remote server address was manually entered, it might not have been entered correctly. There are

three distinct parts to the identity - a name, a separator (the "@" symbol), and the address. Of these,

the separator and address are the key elements. For more information on creating remote database

names (identities), see the topic on manually adding servers to the server list.

The database port number is incorrect

The port normally used (default port) to connect to a remote database is 16000. However, XStudio

supports user-defined port numbers for this connection, so you need to ensure the port you've

assigned for the remote database connection matches the remote database server port that has been

assigned.

The remote PC cannot be reached via TCP/IP

In order for XStudio to connect to a remote database server, it must be able to reach the host PC via

TCP/IP.

If the server address you are trying to reach uses an IP address or internet domain name, ensure that

you have a "route" to the host PC by attempting to "ping" the remote PC. Use the "address" element of

the remote database server identity as the address to ping.

If the server address you're trying to reach uses a machine name notation, ensure that you can browse

to the named machine (the name used in the "address" portion of the remote database identity) using

Network Neighborhood or File Explorer.

Access to the remote PC is blocked

If you are certain that the remote server identity is correct and that you can reach the remote PC,

ensure that both the PC running XStudio and the PC running the host application (and database

server) have port 16000 available for use and unblocked. See the topic on TCP/IP Port Information for

details on all ports used for database communications between XStudio and the host application.

6.4.2 Slow Database Performance

Database performance, meaning how quickly displays are updated and how long it takes to retrieve

information, is generally most affected when using XStudio to access a remote database not located

on your local area network (LAN).

Performance is directly affected by available bandwidth (data flow capacity) between you and the
