Re: JNDI Failure - OutOfMemoryError

Works for me (Well, I get an error because I have no LDAP server. But I do not get the OutOfMemory exception)

I am using 8.1.7.0 on Linux.
SVRMGR> show parameter pool_size

NAME                                TYPE    VALUE
----------------------------------- ------- ------------------------------
java_pool_size                      string  41943040                      
large_pool_size                     string  1024000                       
shared_pool_size                    string  52428800                      

As far as I remember, JNDI does not work on JServer on anything less than 8.1.7.
