    Talking of eportal ...

    Anyone else having any issues with the Tomcat memory leak ?

    apparantly its a known issue an *should* be fixed in the next release of eportal but it doesent appear to be affecting everyone as its not been classed as a major issue, so for now am just reboot the admin server now and again
    just wondering tho if anyone else has this an if its having much of an effect on performance of eportal / cmis ?

    We had terrible problems with this - and the advice we had was to put more memory in, which just meant it took longer for the leak to take hold.

    We now use IIS for dishing eportal out and all of these kinds of problems seem to be solved and the performance overall is very good - it dishes our the inconsistent and incorrect pages much quicker than it used to and without the daily / weekly reboot.

    I was going to say a scheduled services restart and clearing out the audit log seem to be the thing until they fix it.

    Did you do this yourself or did you/the school have help to go to IIS?

    The longer the system was running for the slower it got - reboot the services and everything was fine.

    I think the problem was that when it opened a connection it never really closed it or released the memory associated with that connection.

    We increased the memory in the server (to lots and lots) and the same thing would happen, but over a longer time frame - so reboot once a week rather than once a day.

    oh what excellent advice they do give us :P lets not fix the problem just waste money extending how long it takes b4 you have to do the next reboot

    perhapse i should inquire about changing it to IIS i think this is also affecting my backups as the memory leak prevents the backup from running due to the insufficent memory #-o over night thus casuing even more problems

    thanks for the advice

    Do you run eportal on the same server as the CMIS install? If so then it really is worth splitting it out accross two servers - one for CMIS one for eportal.

    If not then is there anything on the eportal server that needs backing up? Other than a few settings files and perhaps student pictures - none of which changes very often or takes up much room - it is probably as the original install and not really worth backing up.

    We do not back up our eportal server here - all the important data is on the CMIS box.

    Re: Talking of eportal ...

    Why is it not wise to back up the eportal server - there is no data on it and it can be reinstalled in a matter of minutes?

    Re: Talking of eportal ...

    You would need to back-up the webapps/eportal/conf folder and the images folders as these contain any customised xml - ie two week timetables etc etc and student photos etc

    Re: Talking of eportal ...

    @AndyCope - I have copies of all these files on another server which I do everytime I do an upgrade - but they never ever change so there is no need to do a daily or even weekly backup of the eportal server - particularly considering the problems many of you are still having with eportal.

    Re: Talking of eportal ...

    @all Ok this has kinda popped up here but you mind listing (in your opinion) pro's and cons of single or seperate installations please.

    Single:
    Pros: Quicker upgrades
    Less network traffic
    Runs faster

    Cons: Greater strain on server
    Memory leaks
    Problems with ePortal could affect CMIS usage

    Seperate:
    Pros: Can use a lower spec machine
    Can restart eportal server without any affect of CMIS
    Cons: Slower
    Network overheads / traffic
    Slower upgrades

    Re: Talking of eportal ...

    I currently have a two server setup - and it was necessary for a while because of the resources eportal used up.

    But now I would consider going back to a powerful single server setup for all the advantages you listed above - but at the moment it works and I do not want to mess with it.
