After the installation of the CA-CCS 11.2 SP2 components, the Calendar and Event Management daemons are unable to start.

Error message is:

Unable to load library /opt/CA/SharedComponents/ccs/lib/libcajdbc.o

During the initial installation of the CA-CCS 11.2 SP2 components, there was a  file system full condition leading in a partial installation.

Consequence of this is that some symbolic links were missing in /opt/CA/CAlib directory.

A second installation attempt, without cleaning up the first partial installation, did not fix this problem.

Steps to find out what is missing in this particular case where library libcajdbc.o cannot be loaded. 

          ldd /opt/CA/SharedComponents/ccs/lib/libcajdbc.o

               /opt/CA/SharedComponents/ccs/lib/libcajdbc.o needs:
               /opt/CA/SharedComponents/JRE/1.5.0/bin/classic/libjvm.so
                Cannot find libetpki2.so
                Cannot find libetpki2_thread_posix.so
               /usr/lib/libs.a(shr.o)
               /usr/lib/librtl.a(shr.o)
               /usr/lib/libc_r.a(shr.o)

CA Common Services, CA-CCS 11.2 SP2 on AIX. But this problem might happen on any other Unix/Linux platform.

1) Create the missing symbolic links in /opt/CA/CAlib with these commands:

           ln -s /opt/CA/SharedComponents/ETPKI/lib/libetpki2.so /opt/CA/CAlib/libetpki2.so

           ln -s /opt/CA/SharedComponents/ETPKI/lib/libetpki2_thread_posix.so /opt/CA/CAlib/libetpki2_thread_posix.so

2) Verify that the OS loader is able to load library libcajdbc.o with:

           ldd /opt/CA/SharedComponents/ccs/lib/libcajdbc.o

               /opt/CA/SharedComponents/ccs/lib/libcajdbc.o needs:
               /opt/CA/SharedComponents/JRE/1.5.0/bin/classic/libjvm.so
               /opt/CA/SharedComponents/ETPKI/../lib/libetpki2.so
               /opt/CA/SharedComponents/ETPKI/lib/libetpki2_thread_posix.so
               /usr/lib/libs.a(shr.o)
               /usr/lib/librtl.a(shr.o)
               /usr/lib/libc_r.a(shr.o)
               /opt/CA/SharedComponents/ETPKI/../lib/libetpki_openssl_crypto.so
               /opt/CA/SharedComponents/ETPKI/../lib/libetpki_openssl_ssl.so
               /usr/lib/libdl.a(shr.o)
               /usr/lib/libc.a(shr.o)

3) Then start the CA-CCS components with either 'unistart all' or 'unisrvcntr start CA-CCS'

This technical document gives you some details to find out problems when the OS loader cannot load an executable or library due to missing symbolic links or missing dependent libraries.

The problem can also be related to wrong setup of LD_LIBRARY_PATH or LIBPATH variables.
