/lib64/libstdc++.so in [email protected]_2.4 not found. Problem: GLIBC is a 2.17 library and the connection is looking for a 2.14 library. Workaround: Change to static link. See if/USR/LIB64/LIBC.A exists. Modify the ORACLE installation directory: $ORACLE _HOME/CTX/LIB/INS_CTX.MKCTXHX: $ (ctxhxobj)
$ (LINK_CTXHX) $ (ctxhxobj) $ (inso_link) modified to: Ctxhx: $ (ctxhxobj)
-static $ (LINK_CTXHX) $ (ctxhxobj) $ (inso_link)/USR/LIB64/LIBC.A then click Retry Pass.
Problem: undefinied reference symbol ' B_destroykeyobject ', view the log, the actual is not found Nnz11 this library. Workaround: Modify/opt/oracle/product/11.2.0.1/sysman/lib/ins_emagent$ (MK_EMAGENT_NMECTL) to: $ (mk_emagent_nmectl)- Lnnz11 then click Retry to pass.
