(Doc ID 2461196.1)
Last updated on FEBRUARY 03, 2019
Applies to:Oracle WebLogic Server - Version 126.96.36.199.0 and later
Information in this document applies to any platform.
On : 188.8.131.52.0 version, WLS Core Components
Using Forms & Reports 184.108.40.206
Actual Issue : Using F&R 220.127.116.11 with collocated OHS.
And created softlink of OHS Document_Root (htdocs) directory pointing to NAS mount point.
/icesapp/apps/documents -> htdocs
Above “documents” directory have around 3Lac files and when we start the WLS AdminServer or any other managed server, it starts reading/opening files from “documents” directory and doesn’t come up.
Thereafter we copied 1Lac files from “documents” directory to htdocs directory after removing softlink (NAS to SAN) and then it took around 8-9 minutes to come up in RUNNING state.
Strace output shows like below:

Were completely STUCK until came SR # 3-13832807741 where customer resolved this by creating Alias directive mapping the URL alias with the physical directory. Worked perfectly as a workaround!
However, customer does not accept this workaround and wants to know why WLS starts reading and opening files from document_root(htdocs) folder and doesn’t come up.
