The following table describes the event IDs, trace collection points, and PRF trace collection levels.

Table 8-20 Details of trace collection points of the request processing for updating an HTTP session (database session failover functionality)

Event ID	No. in the figure^#1	Trace acquisition points	Level
0x8200	1	Immediately after the acquisition of a request, or after the completion of the request header analysis (via the Web server)	A/B
0x8202	6	Immediately before invoking a servlet or JSP	A/B
0x8203	6	Immediately before invoking the filter that is executed before the execution of the servlet or JSP that receives the request (filter for which the [[dispatcher]] tag of the [[filter-mapping]] tag of web.xml is omitted, or for which REQUEST is specified in the [[dispatcher]] tag)	B
0x8207	6	Immediately before invoking the static contents (DefaultServlet)	B
0x8211	1	Immediately after the acquisition of a request, or after the completion of the request header analysis (via the in-process HTTP server)	A/B
0x8219^#2	8	Immediately before starting the serialization of the HTTP session property information with the database session failover functionality	A
0x8220	4	Immediately before starting the de-serialization of the HTTP session property information with the database session failover functionality	A
0x8221	2	Immediately before starting database access before the Web application processing with the database session failover functionality	A

0x8300	12	Immediately after the completion of request processing (via the Web server)	A/B
0x8302	7	Immediately after the completion of processing of the servlet or JSP	A/B
0x8303	7	Immediately after the completion of processing of the filter that is executed before the execution of the servlet or JSP that receives the request (filter for which REQUEST is specified in the [[dispatcher]] tag of the [[filter-mapping]] tag of web.xml)	B
0x8307	7	Immediately after the completion of processing of the static contents (DefaultServlet)	B
0x8311	12	Immediately after the completion of request processing (via the in-process HTTP server)	A/B
0x8316	7	Immediately after the completion of processing of the filter executed during transfer to the error page is complete (filter for which ERROR is specified in the [[dispatcher]] tag of the [[filter-mapping]] tag of web.xml)	B
0x8319^#2	9	Immediately after the termination of serialization of the HTTP session property information with the database session failover functionality	A
0x8320	5	Immediately after the termination of de-serialization of the HTTP session property information with the database session failover functionality	A
0x8321	3	Immediately after the termination of database access before the Web application processing with the database session failover functionality	A
0x8322^#2	11	Immediately after the termination of database access after the Web application processing with the database session failover functionality	A
