I am using Redhat Linux 4 Now the problem is solved.I installed Postgres 8.1.5 from source code previously it was installed using rpm on slave machine. but then i am having one problem : I am left with following details I am having two machine 1)Master machine : Redhat linux PostgreSQL 8.1.5 -- installed using RPM Slony 1.2.1---installed using Source code 1)Slave machine : Redhat linux PostgreSQL 8.1.5 -- installed using source code Slony 1.2.1---installed using Source code. Its running fine now. but will there be any problem in future as the master and slave PostgreSQL server are installed using diffrent pacakage i.e. master with RPM and slave with source code? I know this is not the solution but for time being its working fine. also could you please suggest me if I installed PostgreSQL with RPM on redhat Linux then which object was that xxid.so (failed to map segemnt from shared object -permission denied)function was refering ? with regards Ashish Karalkar --- Chris <dmagick@xxxxxxxxx> wrote: > Ashish Karalkar wrote: > > Thanks Chris , > > I ahve checked the permissions on the xxid.so file > and > > it ids having all permission i.e. 0777 > > I think its not getting the permission from the > object > > which xxid.so is refering, any idea which object > it is > > refering.... > > Are you running SeLinux by any chance?
