I got slony for the Linux hosts from from slony1-1.2.10.tar, the Windows
hosts from slony-I-1.2.11R-pg82.zip
<http://developer.pgadmin.org/%7Ehiroshi/Slony-I/slony-I-1.2.11R-pg82.zi
p>  , so that might be the problem.

 

I tried installing PostgeSQL 8.2.4 and slony-I-1.2.10R-pg82 on a new
Windows host (not previously installed with PostgreSQL or Slony) and got
the same "Module C:\Program Files\PostgreSQL\8.2\lib\slevent.dll failed
to register. HRESULT -2147023898.  Contact your support personnel."
error.

 

Since this error is being thrown prior to interacting with the Linux
host, it looks like there is more to my difficulty than simply
incompatible versions of Slony.  Either there is something that I don't
understand about the installation procedure or there must be something
about these hosts that is incompatible with the Slony installation.

 

I tried changing the selected features and this error happens if (and
only if) I select the feature "Slony-I server module".  Guessing by the
name, I think I need this feature.

 

As an experiment, I tried installing the various versions from
http://developer.pgadmin.org/~hiroshi/Slony-I/

slony-I-1.2.9R-pg82.zip
<http://developer.pgadmin.org/%7Ehiroshi/Slony-I/slony-I-1.2.9R-pg82.zip
>     didn't throw the HRESULT error the first time I ran it, but
subsequently did.

slony-I-1.2.8R-pg82.zip
<http://developer.pgadmin.org/%7Ehiroshi/Slony-I/slony-I-1.2.8R-pg82.zip
>     , slony-I-1.2.7R-pg82.zip
<http://developer.pgadmin.org/%7Ehiroshi/Slony-I/slony-I-1.2.7R-pg82.zip
>  , and slony-I-1.2.6R-pg82.zip
<http://developer.pgadmin.org/%7Ehiroshi/Slony-I/slony-I-1.2.6R-pg82.zip
>           did throw the error.

 

It seems as though I've mangled something on my computer that prevents
the install script from working correctly, despite cancelling or
uninstalling each time.  I'm inclined to assume the registry as the item
mangled, but am fairly ignorant of how to go about repairing it without
making things worse.

 

I'm running Microsoft Windows XP Professional Version 5.1.2600 Service
Pack 2 Build 2600 .

 

HR Plus decodes the HRESULT as coming from FACILITY_WIN32, defined as
ERROR_NOACCESS, with the text "Invalid access to memory location.".
This makes it sound as though something was trying to access an
inappropriate memory location.

 

Any suggestions would be appreciated.

	I don't understand what you mean by "both of time must not be
different".  Perhaps you meant that they should be the same version; the
Windows host is running "PostgeSQL 8.2.4 on i686-pc-mingw32, compiled by
GCC gcc.exe (GCC) 3.4.2 (mingw-special)", the Linux host is running
"PostgeSQL 8.2.4 on i686-redhat-linux-gnu, compiled by GCC gcc (GCC)
4.1.1 (Red Hat 4.1.1-51)".  This seems like as close to the same version
as is feasible for Windows/Linux, so I hope it's close enough. 


The version of PostgreSQL doesn't matter terribly much (one of the
design goals of slony was to provide a smooth upgrade path between
PostgreSQL major revisions). However the version of slony must match
exactly between all nodes in your cluster.
