But after copying files the installer process displayed an error. Below excerpt from the log.

As this is 18.104.22.168 version and the AIX is 7.1 I was afraid this may be due to some lacks in system filesets or so. It seems not so - all the details You may find in "AIX: ERROR IN INVOKING TARGET 'LINKS PROC GEN_PCSCFG' OF MAKEFILE, ld: 0711-593 SEVERE ERROR: Symbol C_BSTAT (Doc ID 985563.1)" on the Metalink.
