Description

After upgrading the Operating System to RHEL 7 from RHEL 6 the Aleph 23 system is no longer accessible.

The following errors may be seen in this situation:

- In GUI: "Communication error (Global -7) - Failed to read reply."

- Execution error of batch services such as publishing

Execution error : file '/exlibris/aleph/a23_1/aleph/exe/ue_21_a.gnt' error code: 114, pc=0, call=1, seg=0
114 Attempt to access item beyond bounds of memory (Signal 11)

Resolution

1. Re-install Cobol license as discussed in article 'How to reinstall the licenses of the COBOL environment for Aleph'

2. Fix libxml 

As soon as the Cobol license is correctly installed:

a. Remove currently installed libxml

mv /exlibris/product/libxml2-2.9.2 /exlibris/product/libxml2-2.9.2.bak

remove any package that MAY have been downloaded,
note – this step sometimes returns an error as there is nothing to delete :

rm -f /exlibris/ftp_from_exlibris/libxml2-2.9.2*

the error you may see :

rm: No match.

b. Use Util SP to Download and install ThirdParty tools. See document 'The Aleph Service Pack Mechanism - sp 23', chapter 9 'Downloading and Installing Third-Party Product Updates'

c. check again, that the Cobol license installation is still intact and the following does not give any error message:

dlib usm01

util y/11/1 Main license file 

d. Restart the PC server (util w/3/3)
