I had upgraded from a very old version but the install failed. So I ran the upgrade callback manually:

::xowiki::upgrade_callback -from_version_name 0.38 -to_version_name 0.138

This only returned a similar error:

while executing
"ns_cache eval xotcl_object_cache ::xo::has_ltree {
if {[db_driverkey ""] eq "postgresql" &&
[db_string check_ltree "select count(*) f..."
(procedure "::xo::db::has_ltree" line 2)
invoked from within
(procedure "::xowiki::add_ltree_order_column" line 5)
invoked from within
(procedure "__upgrade" line 154)
invoked from within
"__upgrade $from_version_name $to_version_name"
(procedure "::xowiki::upgrade_callback" line 12)
invoked from within
"::xowiki::upgrade_callback -from_version_name 0.38 -to_version_name 0.138"
("uplevel" body line 2)
invoked from within
"uplevel 1 $script"

whooo, an upgrade over 100 versions, must be from something like end of 2006!

It seems, as if you do not have an xotcl_object_cache yet, which is created by xotcl-core. Most likely, some more of the support-functions needed by the upgrade script are not loaded in the version you are using. Did the upgrade of xotcl-core went well? Since the upgrade scripts use xotcl-core functions, it might be a good idea to upgrade first xotcl-core, restart the server and then continue with the upgrade of xowiki.

During the upgrade of xowiki, you will find entries "-- upgrading to ..." in your error-log. then you know, if you run the upgrade callback again from which number to start.

The upgrade of xotcl-core went fine. I'll try your suggestion. Thanks, Gustaf.

I was able to incrementally upgrade xowiki but a restart did not eliminate the problem.

I even re-installed xowiki without success. Why doesn't the cache rebuild on boot?

Not sure, i understand what's your state. I read from the first sentence that the error from the update script went away and you could upgrade; that would mean that ns_cache is apparently working... and then you say, you see the ns_cache error again when you fetch an xowiki page?

When you start the server and invoke then an xowiki page: what is the first error you see in your error.log?

What do you mean by reinstall? a fresh OpenACS installation?

who says, xowiki "rebuilds the cache". During startup of the server, every cache has to be created via ns_cache create.

You started the thread mentioning that you recently witched to aolserver 4.5.1. Are you aware, that this version has a built-in ns_cache? You must not load the nscache .so file in your configuration.

What do you get if you run the url /xotcl/version-numbers on your machine?
