We are looking for a MYSQL database expert to help rebuild and / or fix it. Main tasks will involve indexes, proxies, check out the queries, queues and load balance. This is what we think needs to be worked on, however, you are expected to look at the database and fix it according to your experience and expertise. Experience and Expertise is a Must!!!!!!!!!!! Just to give you a simple scenario of our poor performing database. We are an ecommerce website/app , still in beta stage, therefore no real users. However, we currently have about 4 million products. When you try and open a category that has very few products, the page will open very fast. And when you try and open a category with many products its slow. We recently imported about 26 million records to the database. This caused the table into which we imported the products into, not to open. We have since renamed the table, to enable us continue to use the site. These are a few of the issues we need dealt with. If you ...

I would like to process transactions and clear them for the intended destination. Clearing will be based on a set of criteria that will be defined. Ideally, from a high level perspective, the platform will sit between two types of platforms. on one side will be platforms that originate transactions and on the other end will be platforms that terminate. Every transaction will have certain information sets as field one, field two , firld three and field n., assuming that a transaction has the info required in those fields, then the transaction will be cleared for termination. Also depending on the info in one of the fields being less than a certain value, the cleared transaction will be terminated to a certain platform on the termination end. and depending on the info in the same field being greater than a certain value, the cleared transaction will be terminated on another platform on the termination end. In addition, the originating platform can indicate a field of the transaction so t...

Standard source persistence rule is not good enough. We need to make sure additional packets from same source and DICOM UID are sent to same destination. When next TCP session is establish with same source IP but different DICOM UID or differenct source IP then they are just send to next node in the pool which is least busy based on SNMP monitor results. The next connection must ALSO then maintain source persistence based on source IP and DICOM SUID. Need someone who can code an iRule that make all this work: 1. Check source IP and "DICOM UID" field in incoming TCP connections. If combination of source IP and DICOM UID has connected in last X ( configurable) minutes then forward to the same destination in the server pool as last time. ELSE 2.
