Error in aleph_shutdown: "Warning (tab_library_group): Invalid library in tab_library_group"

  • Article Type: General
  • Product: Aleph
  • Product Version: 20
  • Relevant for Installation Type: Dedicated-Direct; Direct; Local;

Description:

After upgrading Aleph with Upgrade Express, when running aleph_shutdown, the following messages appear in the aleph_shutdown log:


stopping batch queue
Load: /exlibris/aleph/u20_1/alephe/tab/tab_library_group
Warning (tab_library_group) : Invalid library in tab_library_group - XXX20
Warning (tab_library_group) : Invalid library in tab_library_group - XXX21
Warning (tab_library_group) : Invalid library in tab_library_group - XXX01
Warning (tab_library_group) : Invalid library in tab_library_group - XXX10
Warning (tab_library_group) : Invalid library in tab_library_group - XXX20
Warning (tab_library_group) : Invalid library in tab_library_group - XXX30
Warning (tab_library_group) : Invalid library in tab_library_group - XXX50
Warning (tab_library_group) : Invalid library in tab_library_group - XXX60

(etc.)
Is this indicative of a problem? What can be done to correct the warnings?


Cause:

When shutting down the queues and daemons, aleph_shutdown reads ./alephe/tab/tab_library_group, as that file contains a list of libraries which share the same lib_batch and UE processes.

These messages occur when tab_library_group contains a library which is not in $aleph_libs. It may contain libraries that are now obsolete (USM20, for instance, is the ILL library used prior to Aleph 20).

These messages are just warnings and have no real effect.

Resolution:

To correct, perform the following commands on the server after signing in as the "aleph" user:

1. echo $aleph_libs
To display a list of all libraries.

2. aet
To move to the ./alephe/tab directory.

3. vi tab_library_group
To open the tab_library_group table for editing.

4. Remove any libraries that appear in the warning messages from aleph_shutdown. If needed, add in any libraries that are in $aleph_libs that do not appear in this list.

5. :wq
To save changes.

No further actions are needed. The next time aleph_shutdown is performed, these warnings will not appear.
