Hi Ricardo,
1- can i delete this microfiles.
If you are getting the same error what I was getting and the files are similar as I've attached in my post, then you can delete those. There will be no issues in deleting those.
2 how to can i resolve this problem.
This is how it was solved:
Execute from command prompt, command similar as :
D:\usr\sap\<SID>\ERS<NR>\exe\sapcpe.exe
list:\\<HOSTNAME(Virtual)>\sapmnt\<SID>\SYS\exe\uc\NTAMD64\scs.lst
pf="D:\usr\sap\<SID>\ERS<NR>\profile\START_ERS<NR>_<Hostname of NODE>"
This had to run from both of the nodes in cluster for both ERS services and then it got resolved..no more .pfl files.
Hope this helps you.
Regards,
Sujit
