Denis R.'s questions

I would like to know the syntax to call datapump commands (expdp/impdp) logged as 'sys as sysdba' from a remote machine.

I know that when logged on the machine which runs the database, I can use :

expdp \"/ as sysdba\"

However, I cannot find how to do this from a remote machine, for example, these does not work :

expdp 'SYS@SID AS SYSDBA'
expdp "SYS AS SYSDBA"@SID

In both case, the error message is :

LRM-00108: invalid positional parameter value [...]

I am using RHEL 6.1 and I would like to configure SELinux to authorize httpd to read all files in some folders (My goal is to make log files available via web access).

• Is this possible without listing explicitely all files ?
• Is this possible without disabling SELinux for httpd ?

I need solution which could be made persistent.

Thanks by advance.
