Since the in the above example rv libraries are not found. To check if all the varriables are loaded please start the adapter in the debug mode and check which varriables are not set. For example in the below debug log snippet since the RV_HOME varriable is not set due to which "ldd libadmqs.so" has "not found" error for the rv libaries.

key: tibco.env.RV_HOME
value:
Setting env variable RV_HOME=

To solve this issue please set the value of Tibco environment variable which is not set. In the above-illustrated example if you set the value of RV_HOME in the admqs.tra file which is present in the adapter's bin directory.
