ARC not working; server not available; "unable to connect"

• Article Type: General
• Product: Aleph
• Product Version: 18.01

Description:
In order to test ALEPH v18 SP 925 on test, I was asked to copy all the tabs from prod to test. I copied the contents of the /tab directories for all of the following: xxx50s, xxx30s, xxx01, plus alephe/tab. After the fact, I realized that
a) I should have backed up alephe/tab before copied into it and
b) I should not have copied all of prod's files in that directory to test.

Although we restored alephe/tab from a recent backup, we're still having some problems. For example, we cannot connect to ARC. We get an error message about the server not being available. Specifically, all we see when connecting to test for ARC, we get:

Unable to connect
Firefox can't establish a connection to the server at xxxxxxxxx.edu:8080.
* The site could be temporarily unavailable or too busy. Try again in a few
moments.
* If you are unable to load any pages, check your computer's network
connection.
* If your computer or network is protected by a firewall or proxy, make sure
that Firefox is permitted to access the Web.

Resolution:
I connected to xxxxxxxxxxx.edu as user crn:

crn@fcat~>hostname
xxxxxxxxxxx.edu

And did the following connection tests:

crn@fcat~>telnet localhost 390
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'. <------------ this message indicates success

crn@fcat~>/usr/iplanet/servers/slapd-arc/check-slapd
crn@fcat~>echo $status
0 <------ status 0 is OK


crn@fcat~>ps -ef | grep ~crn/apache
crn 7855 7776 0 11:26 pts/3 00:00:00 grep /exlibris/crn/apache

The preceding ps command should display multiple ..../exlibris/crn/apache/bin/httpd lines. The fact that it does not indicates that the arc apache is not running.

Therefore, I did:

crn@fcat~>cd ~crn/apache/bin

crn@fcat~/apache/bin>./apachectl stop
httpd (no pid file) not running

crn@fcat~/apache/bin>./apachectl start

Now when I do the ps it shows the proper crn/apache processes:

crn@fcat~/apache/bin>ps -ef | grep ~crn/apache
crn 8325 1 0 11:52 ? 00:00:00 /exlibris/crn/apache/bin/httpd -k start
crn 8326 8325 0 11:52 ? 00:00:00 /exlibris/crn/apache/bin/httpd -k start
crn 8327 8325 0 11:52 ? 00:00:00 /exlibris/crn/apache/bin/httpd -k start
crn 8328 8325 0 11:52 ? 00:00:00 /exlibris/crn/apache/bin/httpd -k start
crn 8329 8325 0 11:52 ? 00:00:00 /exlibris/crn/apache/bin/httpd -k start
crn 8330 8325 0 11:52 ? 00:00:00 /exlibris/crn/apache/bin/httpd -k start
crn 8334 7776 0 11:53 pts/3 00:00:00 grep /exlibris/crn/apache

Please try connecting again.
