Migrating a PASOE instance from 11.6 to 11.7, shared-memory

I have just migrated one PASOE instance from 11.6.1 to 11.7.1 (Windows 7, 64bit). I read (https://community.progress.com/community_groups/openedge_general/f/26/t/33437) that the best way to do migration is to re-create the instance so I created a new instance with 11.7 OEE and redeployed the application. Everything went quite smoothly in this phase.

Then I configured security/authentication in oeablSecurity.properties and oeablSecurity.csv. We use form based authentication with oerealm. I had used this KB article for configuring our old instance: http://knowledgebase.progress.com/articles/Article/How-to-configure-OERealm-authentication-with-PASOE but that article is for pre-11.7 versions. It was not too hard to find the corresponding config files and settings in the new 11.7 instance but it took several trial & error iterations, so it took some time. I hope that article gets updated to be compatible with 11.7.  

After that I was able to start our application but then I started getting errors for some rest requests (that worked ok in 11.6). Server returned error 400. In catalina log file there was an error: "java.lang.IllegalArgumentException: Invalid character found in the request target". It took me a while to figure out that using curly braces in the URLs (e.g. /rest/si/Company?filter={"top":10}) caused the problem. I had to add this line into conf/catalina.properties:

tomcat.util.http.parser.HttpParser.requestTargetAllow={}

Another way would have been to escape/encode the braces in our javascript code (probably the recommended way).

Eventually I got the application running without any more errors. But I have still one more problem left: I can't use shared memory connection to the database from PASOE. From the client I can.  It seems similar to this issue: https://community.progress.com/community_groups/openedge_deployment/f/21/p/14077/51255#51255. I wonder if this is a bug or if I have missed a step in the configuration etc. Does anyone else have experiences with shared-memory connection between PASOE and DB in 11.7.1? Shared-memory connection worked in 11.6.1 Win64.

Another issue with 11.7.1 is that PASOE sometimes leaves a .pid file after shutdown and that prevents it from restarting. You have to manually delete the file before you can start the instance. According to this KB article: http://knowledgebase.progress.com/articles/Article/cannot-clear-pasoe-instance-log-files-check-for-locked-files the problem should be only in Windows 10 + 11.7.0 and fixed in 11.7.1, but I have it in Windows 7 + 11.7.1.

While writing this, I realized that I had 11.7.0 before upgrading to 11.7.1 and I have also 32-bit version of 11.7.1 installed. I might try to uninstall both 11.7 versions and make a clean install with 11.7.1 64-bit and see if that changes things.
