I found the causes of my problems.
One is that libsqlora8 need to be configured with '--with-threads=posix' option because cyrus
imapd runs in multithreaded way.
The other is that environment variables for OCI connection need to provided to the `master'
The first problem is very clear.
However, the second problem is still in question.
When I tested some getenv() function in `master.c', I found that every environment variable such
`ORACLE_HOME' or `LD_LIBRARY_PATH' was missing, though I set those variables for the cyrus user.
Therefore, I added some test codes in the main() function of master.c using `putenv()' function to
add some environment variables ($ORA_HOME, $TNS_ADMIN, $LD_LIBRARY_PATH, etc.), then it finally
My question is why `master' process eliminates the environment variables for the cyrus user.
Is it intended for some reason?
Could anybody comment on my question?
Thanks in advance.
