12c Grid Agent installation issues - Shell path is incorrect or not defined

I am installing 12c Grid Control agent on my server via Enterprise manager. The targer server is a UNIX server with AIX OS on it. I add target host manually, enter authentication information, host name, installation directory, etc. and all goes well untill I click "Deploy Agent" button, then I get the following error: "Shell path is incorrect or not defined.:/bin/bash(SH_PATH),-c(SH_ARGS) on host MyHostName" and details are : "Check the property values in the following files in this order, ssPaths_.properties or sPaths.properties or Paths.properties, in "/u02/app/oracle/middleware/oms/oui/prov/resources" There isn't /u02/app" directory on my target server, only /u01/app/oracle" so I assume the above directory is on the same server as Enterprise manager. Although I did find a directory where I have files of the format ssPaths_.properties - /u01/app/oracle/product/11.2.0.3/oui/prov/resources Since my platform ia AIX, I used file ssPaths_aix.properties On my target server if I run which bash I get /usr/bin/bash and which ssh returns /usr/bin/ssh ahd which sh returns /usr/bin/sh So I edited the ssPaths_aix.properties file so that SH_PATH=/usr/bin/sh but still getting the same error. I have also tried setting to SH_PATH=/usr/bin/bash but nothing seems to make any difference. I am thinking one possibility would be I am editing wrong file. Can anyone help?
