Solutions for this Error:
1) Check if your application server can reach the tuxedo installed directory. Proper permissions must be there on the Middleware directory where the tuxedo installation is done.

2) Since this issue arrives at application server level check the database server is up and running and is accessible to application server or not. TNSPING and LSNRCTL status can be checked to verify the connectivity between application server and database server.

3) Environment variable can be checked for Tuxedo TUXDIR path.

4) Disk space can be checked at the application server machine. Due to low disk space also this kind of initialization failure can come.

5) Check the Application Server and Tuxedo logs for the exact error where it happens.
