Oracle software installation 86% error:
Error in invoking target 'agent nmhs' of makefile
Solution Add the parameters to link the libnnz11 library in the makefile and modify $ORACLE_HOME/sysman/lib/ins_emagent.mk,
Change $(MK_EMAGENT_NMECTL) to: $(MK_EMAGENT_NMECTL) -lnnz11
It is recommended to backup the original file before modification [~]$ cd $ORACLE_HOME/sysman/lib
[ lib]$ cp ins_emagent.mk ins_emagent.mk.bak
[lib] $ vi ins_emagent.mk
After entering the vi editor
Enter /NMECTL in command mode to find,
Quickly locate the line to be modified and append the parameter -lnnz11
The first is the letter l, the next two are the number 1
Retry after save and exit
# To avoid this problem: MOS provides patches
Patch 19692824
During installation of Oracle Database or Oracle RAC on OL7, the following linking errors may be encountered:
Error calling target 'agent nmhs' of makefile '<ORACLE_HOME>/sysman/lib/ins_emagent.mk'. See "<installation log>" for details.
If this error is encountered, the user should choose to continue . Then, after installation is complete, users must download Patch 19692824 from My Oracle Support and apply it according to the instructions contained in the patch readme.
