WORKLOAD ANALYSIS (INTROSCOPE DATA) - Error when opening an RFC connection

Hi all SDNers,

Help is needed on error "WORKLOAD ANALYSIS (INTROSCOPE DATA) - Error when opening an RFC connection".

This error occured on RCA -> Extractor FWK administration and go to managed system (PI) and from the log, i can see some extraction failed due to error message " Error when opening an RFC connection"

consequently, JAVA performance data is not appearing in RCA -> workload analysis but work fine for ABAP and adapter engine.

I've followed below notes and perform the troubleshooting step by step by still to no avail:

Note 1332428 - Missing data in service sessions from BI/CCDB

Note 1257308 - FAQ: Using EarlyWatch Alert

Note 1274287 - End-to-End Diagnostics 7.0 EHP1 SP18 to SP27

Note 1265070 - Diagnostics - Setup of Managed Systems

Note 1010428 - End-to-End Diagnostics

steps that have performed:

restarted agent

enlarge RFC resource cap for solmandiag and none

delete entire SID in SMSY and pull again from SLD, re-setup managed system

restart PI system

i've spent 2 days on troubleshooting this issue but lack of information in SMP and SDN, even in google.

in table E2E_EFWK_STATUS and extractor E2E_JAVA_EXTRACTOR_IF, i see all WLI_ID ended with RC 96, MESSAGE = Error when opening an RFC connection and LASTRECORDS = 0

I strongly believe this is the issue that causing no applicable data found for JAVA data.

fyi, we are on SOLMAN EHP1 SPS27.

Any kind advise is most welcome.

Thanks,

Nicholas Chang
