Web Server

AS 9.1 b50e.Linux. Can not start WS after AS LB installation: libjvm.so:cannot open shared (6572654)

Description

This issue only applies you are using the Sun Java System Web Server with Application Server 9.1 and Load Balancer on a Linux system. In such a case, after installing Application Server and a load balancer, the Web Server may fail to start because libicui18n.so.2 and libicuuc.so.2 are in conflict. These libraries are present in both /opt/sun/private/lib and /opt/sun/appserver/lib.

Solution

The correct libraries to use are the ones in /opt/sun/appserver/lib because lbplugin is built against those libraries. Once you remove the two libraries from /opt/sun/private/lib, Web Server should start without error.

Alternatively, if you do not want to delete the libraries from /opt/sun/private/lib, you can instead put /opt/sun/appserver/lib before /opt/sun/private/lib in LD_LIBRARY_PATH in the Web Server startserv script; that is, replace:

# Add instance-specific information to LD_LIBRARY_PATH for Solaris and Linux
LD_LIBRARY_PATH="${SERVER_LIB_PATH}:${SERVER_JVM_LIBPATH}:${LD_LIBRARY_PATH}:
/opt/sun/appserver/lib:/opt/sun/appserver/lbplugin/lib"; export LD_LIBRARY_PATH 

with:

# Add instance-specific information to LD_LIBRARY_PATH for Solaris and Linux
LD_LIBRARY_PATH="/opt/sun/appserver/lib:/opt/sun/appserver/lbplugin/lib:
${SERVER_LIB_PATH}:${SERVER_JVM_LIBPATH}:${LD_LIBRARY_PATH}"; export LD_LIBRARY_PATH
