postgresql.conf ships with quite modest defaults so be sure to august it for anything more than light use. We recommend for ~4k users;

  • Available Memory = System Memory - OS (1GB for Windows) - Java (100 to 512)
  • effective_cache_size = Available Memory / 2
  • shared_buffers  = effective_cache_size / 4
  • max_locks_per_transaction = 512
  • max_connections =  60
  • checkpoint_segments 30
  • log_min_duration_statement = 10000
  • log_line_prefix =  ''%m: ''

There is a convenient config creator here.

When something unexpected happens Noodle will ask you what you were doing and email a stack trace to Vialect. Bug reports may also be sent to techsupport@vialect.com. Please use saleshelp@vialect.com for any other inquiries.

Please provide the following to help us reproduce and correct issues faster:

  • Minimal steps to reproduce the issue from scratch. Possibly relevant details:
    • The URL
    • The version of Noodle
    • The version of Web Browser
    • The version of Operating System
    • A username and password
    • An ordered list of buttons/links clicked
    • Sample file/data
  • Expected behavior, possible details:
    • 720p mockup of desired appearance with min and max sample data.
  • Actual behavior, possible details:
    • A full resolution screen shot including address and scroll bars
    • Web Browser console output
    • Web Browser network log (HAR)
    • The source of any warning pages (wrong format, missing parameter)
    • The source of any email
    • A zip of the Noodle/log folder
  • Observe email educate
    • A short descriptive email subject
    • Reply to the email thread only for the same issue
    • Don't make new threads for the same issue.
    • Avoid requesting thread history review.
    • Do not place legal or print notes in signatures or otherwise bloat them.
    • Use text in favor of images
    • Use attachments not overlays/embeds of images or text
    • Be concise.

Leaving out information leads to Vialect spending less time creating solutions and more time attempting to reproduce issues and linking to this page.

The first encrypted request after starting Noodle can be 3 orders of magnitude slower than normal due to random entropy pool depletion. If your server suffers from this issue (most EC2 servers) you can verify by checking the pool size:

cd /proc/sys/kernel/random/ && cat poolsize entropy_avail

There are at least 3 solutions to a depleted pool:

1 Hardware

Some hardware includes random generators (like the rdrand CPU flag):

grep -ic rdrand /proc/cpuinfo

You can enable its use with:

Debian/Ubuntu

apt install rng-tools
systemctl start rng-tools.service
systemctl enable rng-tools.service

Fedora/RedHat

yum install rng-tools
systemctl start rngd.service
systemctl enable rngd.service

2 urandom

If you don't have a hardware generator or you don't trust it you can edit /opt/Noodle/multiserver to use:

-Djava.security.egd=file:///dev/urandom

Or edit java.security in $JRE8/lib/security or $JRE9/conf/security to use:

securerandom.source=file:/dev/urandom

3 haveged

For higher throughput and lower CPU usage than urandom haveged can be used but it can still block:

Debian/Ubuntu

apt install haveged
systemctl start haveged.service
systemctl enable haveged.service

Fedora/RedHat

yum install haveged
systemctl start haveged.service
systemctl enable haveged.service
