Using Debugging Parameters in the Registry to Troubleshoot Errors
The Netscape Application Server registry contains several parameters that help you in debugging. When you experience problems with a certain module, turn on the appropriate debugging registry switch to collect information in the error logs. After you change a registry parameter, be sure to restart the Netscape Application Server.

All parameters that affect the error logs should be turned on only when diagnosing existing problems. Remember to turn the parameters off after you finish debugging. Otherwise, the log file will continue to rapidly increase in size and take up disk space on your machine.

The following table lists Netscape Application Server debugging parameters in the registry.

Module
Parameter
Description
Acceptable Values
Data Access Engine (DAE)
CacheDebugMsgs
Enables DAE to output information to the error log about each of the supported drivers (ODBC, DB2_CLI, INFORMIX_CLI, ODBC_CLI, and SYBASE_CTLIB). The number in parenthesis at the end of a debug message is the connection number to which the message applies.

0 - Turns debugging off
1 - Turns debugging on.

Data Access Engine (DAE)
SQL DebugMsgs
Enables printing of all SQL statements executed on Netscape Application Server consoles.
0, 1

Web Connector Plug-in (HTTPAPI)
DebugMode
Determines the amount of information that is dumped to the error log of the Web Connector Plug-in.
0 (default) - Provides the minimum amount of error information.
1, 2 - Provide increasing amounts of information beyond what 0 provides.
3 - Provides the maximum amount of error information.

DSync
SyncDebug
Controls debugging for data synchronization

0 - Turns debugging off.
1- Turns debugging on.

Load Balancer (LOADB)
Log
Determines the kind of information that the Load Balancer outputs to the error log.

1 - Provides more information about request redirections.
2 - Provides more host statistics
4- Provides more AppLogic statistics

Values are bit positions that can be OR'd together, depending on the level of debugging detail you want. For example, a value of 3 (1 2) provides a combination of request redirection and host information.

Connection Manager
(CONN)
DebugLevel
Outputs more information on CONN-related events such as Connections, sends, receives, connection breakage, etc.
A value of 1 through 4, with 1 being least verbose and 4 being most.
1 - Logs information about a new connections and connection close.
2 and 3 - Log information about activity that checks if other machines in the cluster are active.
4 - Logs information about every packet sent and received.
