Last updated on FEBRUARY 27, 2018
Applies to:Oracle Database - Enterprise Edition - Version 188.8.131.52 to 184.108.40.206 [Release 8.1.7 to 12.1]
Information in this document applies to any platform.
There are cases when a database was started from an environment that did not have all the variables set correctly and this can cause troubles afterwards. Typical examples are :
- starting a database from an environment where ORACLE_HOME has a path with a final forward slash ( "/u01/oracle/220.127.116.11/db_1/" rather than "/u01/oracle/18.104.22.168/db_1")
- starting the database from an environment that points with the TNS_ADMIN parameter to the wrong sqlnet configuration files
- starting the database with the incorrect value for LD_LIBRARY_PATH (LIBPATH for AIX or SHLIB_PATH for HP)
- starting the database from an environment that does not have the ORACLE_UQNAME variable set, although this is used to derive the path to a TDE( or SSL ) wallet.
This note presents the methods to be used to find out the values of the environment variables used by the database processes.
