After a patch/hotfix is applied on the TIBCO Data Virtualization(TDV) 8.3.1, the TDV Server may fail to start again. This article provides the remedy for it.   

Follow the below steps:

(#1) Stop the TDV Server services: repo, monitor and cache.  

(#2) Backup the original files: Make a copy of the following files and save it at another location outside TDV Server Installed directory:
a. [TDV_Server_dir]/apps/server_files.xml
b. [TDV_Server_dir]/conf/server/server_values.xml
c. [TDV_Server_dir]/conf/server/server.properties
d. [TDV_Server_dir]/bin/composite_server.sh

(#3) Replace the following values in each of the above file to point to your TDV Installation Server Directory.
Change 1:  /home/svcdv03/dev/projects/dvtools/java/jdk-11.0.7   to [TDV_Server_dir]/jdk
Change 2: /home/dv/svcdv03/dev/projects/dvtools/postgresql/postgresql-9.6.8   to [TDV_Server_dir]/repository
Change 3: /home/dv/svcdv03/dev/projects/dvtools/postgresql/data/postgresql.conf  to [TDV_Server_dir]/repository/data/postgres.conf
Change 4: /home/dv/svcdv03/dev/projects/dvtools/postgresql/data_cache/postgresql.conf to [TDV_Server_dir]/repository/data_cache/postgres.conf
Save the changes to the files.
Note: [TDV_Server_dir] is the path to the TDV Server installation directory without the box brackets.  

Example for Change 1:
For TDV Server on Windows, will update  '/home/svcdv03/dev/projects/dvtools/java/jdk-11.0.7' to 'C:/Program Files/TIBCO/TDV Server 8.5-9010/jdk' (without quotes)
For TDV Server on Linux, will update  '/home/svcdv03/dev/projects/dvtools/java/jdk-11.0.7' to '/TIBCO/TDV_Server_84/jdk' (without quotes)

(#4) Restart the TDV Server services and follow the steps to apply patch/hotfix.
