Unable to locate 'ar' utility in path
Unable to locate all utilities with system path.
PATH = /usr/bin::/usr/sbin

Investigation Done
The required operating system utilities such as 'ld', 'ar', 'make' are located in /usr/ccs/bin on most releases of unix. This path should be referenced in the unix PATH environment variable.

Resolution
1. Locate the missing utilities. On most releases of unix, they are in /usr/ccs/bin
2. Include a reference to the utilities path in the $PATH environment variable for the applmgr user used to manage the instance. Remember to export the PATH for changes to take effect.
3. Give the following command on terminal to set the path:
export PATH=/usr/ccs/bin:$PATH
