While doing emctl at DBTier, i encountered with undefined path.

/nfs/bld/d26/PRDXBLD9/db/tech_st/11.1.0/cfgtoollogs/emca/VIS1213/emca_repos_create_.log 

Reason:
The central inventory may be corrupt which may lead to undefined directories to be populated at the executable of bin directory.

Fix:
Manually edit the following files

vi $ORACLE_HOME/bin/emca
vi $ORACLE_HOME/bin/emctl
vi $ORACLE_HOME/bin/EMDeploy
vi $ORACLE_HOME/bin/emtgtctl
vi $ORACLE_HOME/bin/emutil
vi $ORACLE_HOME/bin/eusm
vi $ORACLE_HOME/bin/emagentdeploy.pl
vi $ORACLE_HOME/sysman/config/emomslogging.properties
vi $ORACLE_HOME/sysman/config/emca.properties
vi $ORACLE_HOME/sysman/config/emd.properties
vi $ORACLE_HOME/sysman/config/emd.properties.emca
vi $ORACLE_HOME/sysman/config/emagentlogging.properties
vi $ORACLE_HOME/sysman/lib/env_emagent.mk
vi  $ORACLE_HOME/bin/targetdeploy.pl

Then export ORACLE_BASE

then issue the command:
emca -config dbcontrol db -repos create

It should complete successfully
