writeDiagnostics() method of OAF

Hi All, for the first time I am writing any blog. In this I've tried to share my OAF knowledge with all. Kindly bear with me and my language :). Your comments will be highly appreciated to improve it.

For creating logs from OAF java pages  writeDiagnostics() method is used.

writeDiagnostics(Object module ,String message,int logLevel);

module - current module, usually the "this" pointer

messageText - message to be included in the log. Limit 4000 characters.

logLevel - category or type of log message. Valid values are are from OAFwkConstants. (UNEXPECTED,ERROR, EXCEPTION,EVENT,PROCEDURE,STATEMENT,PERFORMANCE)

In controller this method can be accessed by OAPageContext class object
pageContext.writeDiagnostics(this,"Write Log",OAFwkConstants.STATEMENT) ;

While in AM, VO and EO the method can be accessed by the OADBTransactionImpl class object
OADBTransactionImpl.writeDiagnostics(this,"Log Message",OAFwkConstants.STATEMENT) ;


Set the profile option FND: Debug Log Level at user-level.


The logs written through this method can be viewed by enabling the Diagnostics on the OA Pages.

In DB the logs can be accessed by querying FND_LOG_MESSAGES.
