Refresh (F5) Operation Hangs At 'Loading Summary Data' And Opening Project(s) Hang At 98% Due To High Wait Event In P6 Optional Client

(Doc ID 1369370.1)

Last updated on DECEMBER 14, 2017

Applies to:

Primavera P6 Enterprise Project Portfolio Management - Version 8.1 4.2 and later
Primavera P6 Professional Project Management - Version 8.1.1.0 and later
Information in this document applies to any platform.

Symptoms

After working in the P6 Optional Client and when selecting Refresh (F5), the application appears to present a 'Loading Summary Data" dialog box repeatedly and can hang at certain times causing perceived performance degradation.

Another symptom of this issue is that when opening project data the 'Loading Data' window will hang at the 98% marker and when reviewing a trace of the operation, a high "SQL*Net message from client" wait event is occurring at the following SQL statement causing the delay:

SELECT st.risk_id,st.scoretype_id,st.proj_id,st.threshold_id
FROM
RISKIMPACT st,PROJSHAR prj WHERE (st.proj_id = prj.proj_id and SESSION_ID =
22916 AND LOAD_STATUS = 'L') ORDER BY 1,2
This will occur the most when User Preference start-up filters for Resources are set to 'View All Data'.
