![]() I suspect this is still the right direction, but I don't know what should go in place of MD2, or if this is really even the correct solution. After much Googling for similar errors the the best solution I could come up with was to add the following to /opt/sqldeveloper/sqldeveloper/bin/nf, which did not fix the problem or change the error:ĪddVMOption =MD2 I'm not a java developer and I don't really know how to correct this. I'm kind of at a loss as to how to get around this. Status : Failure -SSL error: : Certificates do not conform to algorithm constraints selinux has been disabled temporarily on the vm for testing purposes.Īfter installing SQL Developer, openjdk, openjfx, and passing the path of my openjdk installation as requested by SQL Developer, loading the postgresql JDBC driver, and attempting to connect to the database, I get this error: ![]() ![]() A certificate will then be requested from the client during SSL connection startup. I have confirmed that I can successfully connect to the database from the vm host via psql on command line. To require the client to supply a trusted certificate, place certificates of the root certificate authorities (CAs) you trust in a file in the data directory, set the parameter sslcafile in nf to the new file name, and add the authentication option clientcertverify-ca or clientcertverify-full to the appropriate hostssl line(s) in nf. On my Windows work computer, I can successfully connect to the database on a similar vm using SQL Developer. In production it would be deployed to bare metal, this vm is just for my own testing needs. It's part of the application I support for work, and I cannot make any configuration changes to the contents of the VM itself. I have a postgresql 9.3 database running in a RHEL 6.2 kvm virtual machine.
