Ongoing Stability Issues

jclark58

Both client and my development version is running Version 3.0 Build 1044

If the same application has been running fine on Linux and has problems in shared environment, then the problem is lack of memory - it's as simple as that

jclark58

So you are saying that 256 MB memory allocated to Each process (JBOSS TOMCAT and AWAREIM) as identified in my post in 30 Feb above, is not enough? How much should be allocated and how should I determine when I do have enough?

aware_support

It doesn't matter how much you allocate if there is not enough physical memory!! Or if the shared environment has only so much to spare.

jclark58

OK apart from reiterating that the shared environment has something in the order of 64GB physical RAM and the VM has 4GB allocated and total RAM and seems to be operating at about 32% capacity, the system admin has now agreed to build a physical machine to prove me / us wrong.

Catch is I get to do the work for free if the problems are still there - Im suggesting to him that the cost will be exactly the price of the update to V4 if I / we (meaning you and me) are right. I guess this means I still get to do the work for free but at least we will resolve one impasse.

I hope this at least will make you guys feel better.

Hi jclark58 and all,

Firstly, I empathise completely with jclark58. There is nothing as bad as a disgruntled customer - especially when the supplier has done nothing wrong.

Secondly, I empathise completely with AwareIM support. There is nothing as bad as a disgruntled customer - especially when the supplier has done nothing wrong. Have I said that before ?

As a newbie user and learner of AwareIM, I want to record fairly my experience thus far (about 5 months of using the product till now).

Support from AwareIM is simply the best I've encountered in my 30 years + of the IT industry. They respond quickly and professionally to queries and display a positive inclination to resolve their customers' issues in a manner too rarely experienced in this industry.

The product is stable, reliable and robust, and certainly one of the most user-friendly in its class.

This is my experience and also the overwhelming experience of the many users and contributors who feature on the forums. It's actually difficult to find negative comment from anyone. So fair is fair, no-one should take jclark58's issue as an imbalanced reflection on AwareIM's product or support service.

I'm sorry that jclark58 is having such site-specific issues (we've all encountered similar), but must admit that I don't think the forum is a place to discuss such specifics.

The forum and contributions from people like tford and pbrad is a souce of much assistance and learning. Every post you read has some useful knowledge to be gleaned by the reader. Regrettably this particular thread has nothing to offer, and consequently I feel the discourse between customer and supplier contained herein would be better addressed in direct correspondence between the two.

To jclark58 - I hope you get your customer's problem sorted.

To Aware support - I hope you get your customer's problem sorted.

To all - Keep up the good work !!

OK this may be related to some of the errors we have been seeing with "inconsistent operation" - when clicking on an item in a query to open its edit form the query is redisplayed and the form does not open.

Browser error reporting was turned off but when we turned it on we noticed thet the page was displaying two errors

Line 63 Unterminated string constant
Line 161 Object expected

here is a copy of the link - using right click Copy Shortcut

Any ideas?

Just to keep everybody posted Support have looked at our site and have seen the problems. They remain of the opinion that this is a memory issue so we are building a separate physical machine to test outside the VMWare environment.

A Google for "java vmware" has resulted in the following interesting links in case anyone else is exploring this area.

Some investigations into different Java memory management behaviour between VMs and physical machines.
http://communities.vmware.com/thread/104899

A whitepaper from VMware on how to optimise for Java applications http://www.vmware.com/resources/techresources/1087

This is a comprehensive document with some quite detailed information on determining memory sizes for java applications and the heap in particular. There is an interesting comment suggesting only running one java vm per VMware virtual machine to allow it to do better memory management.

I assume this means running the TOMCAT, JBOSS and AWAREIM processes on separate virtual machines. I would be interested in thoughts about this and in particular what config changes would need to happen.

After a support ticket has been purchased we had a look at the server remotely. It turned out that the problem was related to MySQL connection issues - there was an object configured to use an external connection and this connection didn't work (presumably because it was configured incorrectly or the machine was not available).

jclark58

Yes there was a reference to an external mysql table that was used to populate a dropdown box in the form that was not opening. The domain for this database was redelegated about a week ago and it was decided not to transfer the database. I knew a there was a BO that I was using to look at data in this database but had forgotten about the reference.

This could possibly affect some of the other preexisting issues too - as the mysql database was being accessed over the Internet there could well be latency issues as a result that caused some of the other behaviours.

At least the client is happier now. Thanks AwareIM.
