Description:

When trying to run a search on z39.50 message "Temporary system error" returns. This might also happen when trying to display a record.

In addition you'll find the following in the log file $LOGDIR/z39_server_log:

10:42:51-21/11: /exlibris/aleph/a18_2/aleph/exe/z39_server(8058) [log] find_request_buf=wau=(rushdie), adjacency=N
recv: Interrupted system call
10:42:51-21/11: /exlibris/aleph/a18_2/aleph/exe/z39_server(8058) [warn] Search: communication failure (code -7)
10:42:51-21/11: /exlibris/aleph/a18_2/aleph/exe/z39_server(8058) [log] [2] Temporary system error

Resolution:

(1)   The following line is missing from $alephe_tab/tab_version:
SER1.0 ALEPH Y 0

Adding the line solves the problem.

(2)   The record to display is very long. In some cases this happened because there are too much CAT fields in the record. Solution is to avoid the CAT fields to be displayed. Add the following to your configuration:
 

xxx01/tab/tab_expand (New line) 
Z39_SERVER fix_doc_do_file_08 cat_fix 

xxx01/tab/import/cat_fix (New table) 
! 2 3 4 5 6 7 8 9 
!-!!!!!-!!-!-!!!-!!!-!!!!!-!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!-!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 
1 CAT## DELETE-FIELD 

For both 1 and 2, restart of pc server and z39.50 server is required in order to activate the modifications.
