Memory problem
Locked
 
|
Hi All,
I have some issues with the memory. I have an application which does some DB selects, open some external files to read data and to open up in a Text Editor. But i does this the physical memory shoots up. After i finish with my application also the physical memory of the system doesn't comes down.
When i open the external files i properly close that and there are no undeclared variable or Singleton classes.
Can anyone suggest me what might be cause that my application is not dumping the physical memory after the execution of the program. I use VW7.6.
Thanks and Regards,
Sree

Without knowing more specifics, perhaps the problem is that memory was
allocated that later cannot be freed because it is still holding on to some information that does not fit somewhere else. You may want to read the docs about memory management that are in the doc folder. On 8/5/2010 4:09 AM, Sreenath G K wrote: > Hi All, > I have some issues with the memory.

In reply to this post by Sreenath
Are you looking at the DB2 ( presume DB2/ Oracle ) having some issues because their parameters are not correctly set..? Especially as mem remains high after VW quits. -Skrish

HI all,
Hope my previous post are bit vague and i will try to explain what i I am working windows XP professional.. and all the memory related 1) I opened a new fresh Image VW 7.6. Loaded the PostgresSQLEXDI 2) I opned ADHOC connected to my postgres DB on which it have a record 3) I used the select * from my_table and the memory shoot upto 75MB. 4) I closed the connection closed ADHOC and still the memory is not
dumping which is used in the select. 5) I did the forced GC collect.. but still its not resturning to the
previous state of close to my 23MB when i opened the image. If i do the select again the mmeory will be raised from 75MB to some 100+
I did the same steps ( 2-4) which ADHOC connected to SQL databese. When i effect the select the memory shoot up and as soon as i disconnected the connection to DB the memory was dropped close to my 23 MB mark, but a little up to be precise its 25MB. So anyone have some idea why this happens and any solutions to this Thanks and Regards, On Mon, Aug 9, 2010 at 6:37 PM, Sudhakar Krishnamachari <[hidden email]> wrote:
