During an Installation of SAP Business Objects 4.1 SP07 with DB2 11.1 Database, we have encountered an error after giving CMS DB & Port & click on Continue –
Database access error. Reason Loading shared object failed. First tried to load library db2 and failed because of error: [db2: cannot open shared object file: No such file or directory]. Second tried to load library libdb2.so and failed because of error: [/usr/lib64/libxml2.so.2: symbol gzopen64, version ZLIB_188.8.131.52 not defined in file libz.so.1 with link time reference]. (FWB 00090)
As this error is misleading where SAP suggest to perform some steps at DB2 level for SAP note search for BO 4.1 but in our case this error is something related to Library files which are missing in Installation Folder.
We found the solution in SAP BO 4.2 SAP notes which are listed below –
As per SAP Note – 2689156 – BI 4.2 SP05 installation failed with DB2 11.1 on Linux 7.3&7.4
Download the 3 files libxml2.so, libxml2.so.2, libxml2.so.2.9.5 from the attachments.
Place these 3 copied lib files in the dunit folder of the downloaded setup files of SBOP BI PLATFORM
ex: BusinessObjectsServer/dunit/platform.services.cms.cpp.dbcheck-4.0-core-64. (So that we have both the compatible versions of libxml2.so and its dependents libz.so files in DU directory.)
Run the install setup.sh, It should smoothly proceed with the installation after replacing.
The above solution works like CHARM in our case & we have successfully installed BO 4.1 SP7.
I believe this post helps.
