Article Type: General
Product: Aleph
Product Version: 18.01

Description:
Because of a problem in the upgrade we needed to roll back to Aleph v18. I followed the instructions in Appendix D of the AIK manual for re-linking Cobol. However, now when I try to start Aleph I'm getting this error message:

/exlibris/aleph/a18_1/aleph/exe/rts32: error while loading shared libraries: libcobrts.so: cannot open shared object file: No such file or directory

Resolution:
Looking in the /exlibris/aleph/a18_1/product/local directory, I see this:

lrwxrwxrwx 1 aleph exlibris 24 Aug 16 10:47 cobol -> /exlibris/product/cobol5/
drwxrwxr-x 18 aleph exlibris 4096 Aug 16 11:57 cobol_old/

So it still has the link to /exlibris/product/cobol5/ created as part of the v20 install. It needs to be reverted to the cobol_old.

You do this by:

> cd /exlibris/aleph/a18_1/product/local
> rm cobol
> mv cobol_old cobol
