  • Database triggers / referential integrity and in-memory caching

    - by Ran Biron
    Do you see database triggers / referential integrity rules being used in a way that changes actual data in the database (changing row w in table x causes a change in row y in table z)? If yes, How does this tie-in with the increasing popularity of in-memory caching (memcache and friends)? After all, these actions occur inside the database but the caching system must be aware of them in order to reflect to correct state (or at least invalidate the possibly changed state). I find it hard to believe that callbacks are implemented for such cases. Does anyone have real-world experience with such a setup / real-world experience with considering such a setup and abandoning it (which way did you go? if caching, how do you enforce integrity?)

  • static images aren't caching with php-generated page

    - by scootklein
    Our website was just converted to being generated by mod_rewrite and php scripts. Images aren't caching in browsers when they seemingly should be. All images follow format: <img src="/images/header.png" /> I must avoid the script completely caching because the PHP parser needs to handle each page dynamically on each request; however, the download overhead of the large images is cumbersome on every single page load. I would ideally provide headers for "Cache-Control: no-cache, must-revalidate" and "Expires: some_date_in_the_past" to force revalidation of the PHP script. Why isn't the browser caching static images with consistent href values across all pages?

  • Performance-optimizing Oracle 10g on a server that is also a Tomcat JSP app server?

    - by PKHunter
    I have inherited a simple RedHat 5 - 64bit platform. It has SCSI disks on RAID1, with 16GB of RAM. Double Core CPU. Oracle 10g, Release 2. This would be a decent platform for running the DB only, perhaps, but the same server in an "A-A mode" clustering (very simple) also runs Tomcat and there are several Java servlets running on this. Sadly there is no caching platform etc. We only use an external CDN for some html caching. I am personally more familiar with web environments on the LAMPP platform (apache, php, mysql, postgresql). PROBLEM: Because the server has both Tomcat JSP/Java and Oracle 10g running on the same server, with no caching, I have some issues of the server going down. Often, sadly. QUESTION: What are my options in terms of improving performance of all these different apps? Connection Pooling? Example, in Postgresql world we have PgBouncer, which really helps things. Does Oracle have something similar? Or is there a famous Java-based external pooler that people use in production environments? (I'm not familiar with Java) Any "SQL cache" as in the MySQL and Postgresql world? Any other kind of application cache, as "APC" or "eAccelarator" in the PHP world? The "OSCache" stuff from the Java world (JSP thingie I found on Google: http://onjava.com/pub/a/onjava/2005/01/05/jspcache.html?page=2) ... What else? Sorry if this is a noob question. I have googled and googled, but problem is I don't know what to google for, other than the broad general concepts above. So if not full answers, I would even appreciate basic pointers and I am happy to JFGI myself. Thanks!

  • test php disabled caching

    - by user1691389
    My site had a problem in that certain browsers (especially opera and gecko) were "over-caching" (caching far too much for my taste). I've just added the following PHP snippet to hopefully disable caching in all browsers: <?php header("Expires: Tue, 01 Jan 2000 00:00:00 GMT"); header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0"); header("Cache-Control: post-check=0, pre-check=0", false); header("Pragma: no-cache"); ?> Question: How would you test this out, to make sure it actually works?

  • How to enable caching on Apache2 (using as load balancer)

    - by csl
    I'm using Apache 2 as my load balancer (mod_jk). I've 2 Tomcat servers behind my load balancer. What I'm trying to do is to enable caching of my static pages in my load balancer using mod_cache but nothing seems to be working. I confirmed this by creating a simple JSP page that prints out current date time and I always get the latest date time (indicating that the JSP page is not cached). OS: Ubuntu

  • Monitoring apache's caching.

    - by Synchro
    I'm running mod_mem_cache with mod_cache, but I don't seem to have any way of telling whether images are served from the cache or not, so I can't tell how well it's working. Is there some way of seeing via mod_status, adding cache status headers to responses or similar? The servers it's on are quite happily handling sustained loads of about 200 requests/sec, but I can't tell if/how much the caching is helping that.

  • Caching issue with Centos forwarding DNS server

    - by Paddington
    I installed a Forwarding DNS server on Centos 5.10 and it is resolving addresses e.g google.com. When I stopped named (service named stop) and tried to dig (dig @localhost A google.com) there was a failure to resolve the address. I checked and see the caching daemon nscd is running. Does this mean the server is not caching at all? How can I get it to cache? named.conf options { // Those options should be used carefully because they disable port // randomization // query-source port 53; // query-source-v6 port 53; // Put files that named is allowed to write in the data/ directory: listen-on port 53 {127.0.0.1; 10.0.0.4;}; directory "/var/named"; // the default dump-file "/var/named/chroot/var/named/data/cache_dump.db"; statistics-file "/var/named/chroot/var/named/data/named_stats.txt"; memstatistics-file "/var/named/chroot/var/named/data/named_mem_stats.txt"; // allow-query {localhost; 192.168.0.0/24; 10.0.0.0/8;}; recursion yes; //allow-query { localhost; 10.0.0.0/8;}; allow-query { localhost; any; }; allow-query-cache { localhost; any; }; forward only; forwarders {8.8.8.8; 8.8.4.4;}; dnssec-enable yes; // dnssec-lookaside auto; /* Path to ISC DLV key */ // bindkeys-file "/etc/named.iscdlv.key"; // managed-keys-directory "/var/named/dynamic"; }; logging { channel default_debug { file "data/named.run"; severity dynamic; }; }; **

  • setting up bind to work with nsupdate (SERVFAIL)

    - by funny_ha_ha
    I'm trying to update my DNS-Server dynamically using nsupdate. Prerequisite I'm using Debian 6 on my DNS-Server and Debian 4 on my client. I created a public/private key pair using: dnssec-keygen -C -a HMAC-MD5 -b 512 -n USER sub.example.com. I then edited my named.conf.local to contain my public key and the new zone i wish to update. It now looks like this (note: I also tried allow-update { any; }; without success): zone "example.com" { type master; file "/etc/bind/primary/example.com"; notify yes; allow-update { none; }; allow-query { any; }; }; zone "sub.example.com" { type master; file "/etc/bind/primary/sub.example.com"; notify yes; allow-update { key "sub.example.com."; }; allow-query { any; }; }; key sub.example.com. { algorithm HMAC-MD5; secret "xxxx xxxx"; }; Next, I copied the private key file (key.private) to another server I want to update the zone from. I also created a textfile (update) on this server which contained the update information (note: I tried toying around with this stuff too. no success): server example.com zone sub.example.com update add sub.example.com. 86400 A 10.10.10.1 show send Now I'm trying to update the zone using: nsupdate -k key.private -v update The Problem Said command gives me the following output: Outgoing update query: ;; ->>HEADER<<- opcode: UPDATE, status: NOERROR, id: 0 ;; flags: ; ZONE: 0, PREREQ: 0, UPDATE: 0, ADDITIONAL: 0 ;; ZONE SECTION: ;sub.example.com.

The zone isn't updated, nor does my nsupdate change anything. I'm not sure if the file /etc/bind/primary/sub.example.com should exist prior to the first update or not. I tried it without the file, with an empty file and with a pre-configured zone file. Without success. The sparse information I found on the net pointed me towards file and folder permissions regarding the bind working directory, so I changed the permissions of both /etc/bind and /var/cache/bind (which is the home dir of my "bind" user).

  • Public DNS redirect subdomain to Windows Server 2003 DNS

    - by user125248
    I'm a programmer by trade but often dabble in sysadmin tasks and responsibilities. I have recently been tasked with setting up a Windows Server 2003 networking environment for a small business with multiple branches. The business already has a domain name they use to host a website at www.example.com. Currently the DNS nameservers are at Zerigo and I would very much like it to remain that way (as they specialize in just providing DNS services and they do this very well). We also have a bunch of other subdomains we use to conviniently connect to the various branches that have static IPs assigned from ISPs, so we're able to connect easily to branch1.example.com. Is it possible to 'redirect' all intranet.example.com DNS requests to a Windows box? I've been doing a little reading and I see there are NS records that might be able to do this, and the Windows DNS server could then perform all of the lookups for that subdomain, say, server1.intranet.example.com or client5.intranet.example.com. This would seem better to me, than registering a new domain name for the organisation, as keeping a single domain name makes more organizational sense.

  • For Australian audiences, would an uncached .com.au domain resolve faster than an uncached .com?

    - by thomasrutter
    Is there any speed benefit to using a .com.au domain rather than a .com if your customers, hosting and DNS services are in Australia, specifically in the worst typical case (domain is not cached in any local DNS relay for customer)? Assuming that both domains pointed to the same nameservers in the end. I know this is mostly academic because we are talking about a DNS lookup that would take at most a few hundred milliseconds and would only be relevant once at the beginning of a session. I just was curious. I know that an uncached .com lookup will involve consulting at least one ?.gtld-servers.net. server and an uncached .com.au will involve consulting at least one ?.au. server. Now, what I guess I'd need to know is Are the various ?.gtld-servers.net. servers using anycast technology that would have local fully authoritative nodes in Australia, making them just as fast to Australians as ?.au. and avoiding a 200ms+ overseas latency, or are some or all of them hosted only in the US or in the northern hemisphere?

  • Why would I be getting IXFR and AXFR transfer denied on my DNS server?

    From everything I've researched and tried, it appears that my named.conf is configured correctly, including the allow-transfer section. Here is a sample of the errors. It is only happening with a couple of my secondary servers, but it is happening for every zone for those servers that are failing. One of the servers is attempting IXFR, the other AXFR. The result is the same: 18-Mar-2011 14:27:51.372 security: error: client 84.234.24.90#59208: zone transfer 'juansgaranton.com/IXFR/IN' denied 18-Mar-2011 14:32:18.015 security: error: client 174.37.196.55#50783: zone transfer 'cheshirecat.net/AXFR/IN' denied Here is the relevant part of named.conf. options { directory "/etc/bind"; pid-file "/var/run/named/named.pid"; files 4096; allow-transfer { 140.186.190.103; 84.234.24.90; 207.246.95.34; 203.20.52.5; 140.186.190.103; 127.0.0.1; 174.37.196.55; }; }; logging { channel "bind" { file "/var/log/bind.log" versions 3; print-time yes; print-severity yes; print-category yes; severity info; }; category lame-servers { null; }; category "default" { "bind"; }; };

  • Is there a method to instantly, dynamically switch between several sets of name servers on a single domain with code?

    - by trnsfrmr
    I usually set name servers at an ISP, they often take 24 - 48 hours to resolve. If one has 2 separate sets of name servers (say from 2 domain parking companies) they want to send traffic to, is it possible to switch between the sets instantly without any delays? To be clear, how do you switch mydomain.com (ns1.nameserver1.com, ns2.nameserver1.com) to mydomain.com (ns1.nameserver2.com, ns2.nameserver2.com) instantly?

  • Best in-memory cache of DB objects for Silverlight [closed]

    - by Jon
    Hi, I'd like to set up a cache of database objects (i.e. rows in a table) in memory in silverlight, which I'll do using WCF and linq-to-sql. Once I have the objects in memory, I'm planning on using MSMQ to receive new objects whenever they have been modified. It's a somewhat complex approach but the goal is to reduce trips to the database and allow instant data communication between Silverlight applications that are connected to the MSMQ. My Silverlight applications are meant to be long-running and the amount of data to be cached will not be large. I'm planning on saving the in-memory cache using local storage. Anyway, in order to process the updated objects that come in, I'd like to know if the user has changed the existing object. Could I use some event relating to data-binding to set a flag indicating that the object has changes? Maybe there's a better way to do the cache entirely? Thanks!

  • Complex knowledge management system with CRM..written internally

    - by JonH
    We've all heard of salesforce and sugarcrm and the likes of systems like this. Unfortunately at my workplace we have been asked to write a similiar system (rather then license or purchase). Basically the database is fairly large. Think of modules such as: Corporate groups, customers, programs, projects, sub projects, and issue management. In simple terms a corporate group has one to many customers. A program has one or more projects. A project has one or more sub projects. And an issue can be created on many sub projects. Of course the system is a bit more complex but instead of listing every single module I think its best to keep it simple. In any event, the system in its current state has only two resources to be working on it (basically we have to do it all: CSS, database, jquery, asp.net and C#). We've started off well by defining the UI master and footer pages that way we can reuse those across all of our pages. Now comes the hard part. The system will have about 4k end users with say 5-10% being concurrent users. We are wondering if it makes sense to cache our database data (For say 5-10 minutes) rather then continously hit our database. The reason being is some of these pages may have 5-10 search filters associated with the page. Imagine every time a selection is made from a search box how many database hits. Also some of these search fields cascade so selecting for instance an initial drop down may cascade several drop down boxes under them. Is it wrong to cache because I am not finding too many articles on whether it is a good idea or not. Remember the system is similiar to say a CRM system where we manage our various customers, projects, sub projects, issues, etc.

  • Point dns server to root dns servers [duplicate]

    - by Dhaksh
    This question already has an answer here: What is a glue record? 3 answers Why does DNS work the way it does? 4 answers I have setup a custom authoritative only DNS server using bind9. Its a Master ans Slave method. Assume DNS Servers are: ns1.customdnsserver.com [192.168.91.129] ==> Master ns2.customdnsserver.com [192.168.91.130] ==> Slave Now i will host few shared hosting websites in my own web server. Where i will link above Nameservers to my domains in shared hosting. My Question is: How do i tell root DNS servers about my own authoritative only DNS server? So that when someone queries for domain www.example.com and if the domain's website is hosted in my shared hosting i want root servers to point the query to my own DNS Server so that the www.example.com get resolved for IP address.

  • Specifying an Internal (LAN) DNS Server in Netgear DGND3700 (N600) router

    - by Mus
    I have a DNS server running on a linux machine on my LAN which has domains for a few devices in my LAN. The resolve.conf file has google and the isp nameservers in it, as well as itself. Dunno if that helps or hinders but this setup has worked for years. I used to have a Thomson 585 ADSL router where I set the internal DNS Server as the primary DNS and the ISPs DNS server as the secondary. True enough all connected devices could access domains specified in the internal DNS. Recently I had to replace the Thomson router with a Netgear DGND3700 (N600) ADSL router. The problem is that if I specify the internal DNS server in this router, I lose internet connection as well as connection to the router itself. Does anyone know how I can use the internal DNS as the primary in the router?

  • Excessive CPU Utilization for Bind 9.8.1 `named` processes

Or how to debug this. top top - 14:13:08 up 25 days, 14:16, 1 user, load average: 1.04, 1.04, 1.05 Tasks: 149 total, 1 running, 148 sleeping, 0 stopped, 0 zombie %Cpu(s): 17.3 us, 4.3 sy, 0.0 ni, 78.2 id, 0.1 wa, 0.0 hi, 0.0 si, 0.0 st KiB Mem: 2042776 total, 1347916 used, 694860 free, 249396 buffers KiB Swap: 3976080 total, 30552 used, 3945528 free, 574164 cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 17445 bind 20 0 244m 42m 3124 S 99.4 2.2 2345:03 named rndc stats +++ Statistics Dump +++ (1352931389) ++ Incoming Requests ++ 65869 QUERY ++ Incoming Queries ++ 31809 A 241 NS 3 CNAME 27455 SOA 276 PTR 123 MX 462 TXT 5400 AAAA 7 A6 1 DS 14 DNSKEY 15 SPF 55 AXFR 8 ANY ++ Outgoing Queries ++ [View: internal] 22206 A 509 NS 10 SOA 25 PTR 12 MX 524 TXT 4851 AAAA 62 DNSKEY 19 SPF 3157 DLV [View: external] 87 A 2 NS 80 AAAA 120 DNSKEY 7 DLV [View: _bind] ++ Name Server Statistics ++ 65869 IPv4 requests received 27670 requests with EDNS(0) received 112 TCP requests received 65652 responses sent 20 truncated responses sent 27670 responses with EDNS(0) sent 62920 queries resulted in successful answer 37117 queries resulted in authoritative answer 28482 queries resulted in non authoritative answer 7 queries resulted in referral answer 591 queries resulted in nxrrset 53 queries resulted in SERVFAIL 2081 queries resulted in NXDOMAIN 14530 queries caused recursion 162 duplicate queries received 55 requested transfers completed ++ Zone Maintenance Statistics ++ 109536 IPv4 notifies sent ++ Resolver Statistics ++ [Common] [View: internal] 29362 IPv4 queries sent 2013 IPv6 queries sent 28531 IPv4 responses received 4209 NXDOMAIN received 6 SERVFAIL received 31 FORMERR received 32 EDNS(0) query failures 3359 query retries 836 query timeouts 5348 IPv4 NS address fetches 3271 IPv6 NS address fetches 83 IPv4 NS address fetch failed 2779 IPv6 NS address fetch failed 17421 DNSSEC validation attempted 12731 DNSSEC validation succeeded 4690 DNSSEC NX validation succeeded 21104 queries with RTT 10-100ms 7418 queries with RTT 100-500ms 3 queries with RTT 500-800ms 1 queries with RTT 800-1600ms [View: external] 192 IPv4 queries sent 104 IPv6 queries sent 192 IPv4 responses received 2 NXDOMAIN received 104 query retries 44 IPv4 NS address fetches 44 IPv6 NS address fetches 1 IPv4 NS address fetch failed 1 IPv6 NS address fetch failed 4 DNSSEC validation attempted 3 DNSSEC validation succeeded 1 DNSSEC NX validation succeeded 152 queries with RTT 10-100ms 40 queries with RTT 100-500ms [View: _bind] ++ Cache DB RRsets ++ [View: internal (Cache: internal)] 2007 A 652 NS 131 CNAME 1 MX 32 TXT 421 AAAA 28 DS 244 RRSIG 110 NSEC 3 DNSKEY 2 !A 2 !TXT 89 !AAAA 2 !SPF 14 !DLV 148 NXDOMAIN [View: external (Cache: external)] 55 A 12 NS 34 AAAA 2 DS 10 RRSIG 1 DNSKEY [View: _bind (Cache: _bind)] ++ Socket I/O Statistics ++ 82958 UDP/IPv4 sockets opened 2118 UDP/IPv6 sockets opened 4 TCP/IPv4 sockets opened 1 TCP/IPv6 sockets opened 82956 UDP/IPv4 sockets closed 2117 UDP/IPv6 sockets closed 58 TCP/IPv4 sockets closed 15 UDP/IPv4 socket bind failures 2117 UDP/IPv6 socket connect failures 29554 UDP/IPv4 connections established 59 TCP/IPv4 connections accepted 2117 UDP/IPv6 send errors 5 UDP/IPv4 recv errors ++ Per Zone Query Statistics ++ --- Statistics Dump --- (1352931389)

  • nameservers one domain one VPS and one VMCloud

    - by Dave
    I 'had' just a single VPS with nameservers ns1 & ns2.mydomain.com. I've now taken a VMCloud package as I need space etc. Ultimately I will carefully transfer all accounts from my VPS to Cloud but in the short term I'm running both. In the new WHM on Cloud I have set hostname bla.domian nameservers as ns3 & ns4.mydomain.com with the two new ip addresses. Question is do I need to do anything else - eg where mydomain.com is registered? I want ns1 & 2 point to VPS and ns3 & 4 to point to Cloud.

  • Possible to direct naked domain to external IP

    - by Luke
    So I found this post: configure Bind to have a custom domain on tumblr and I was trying to ask a related question: Would it be possible to set up an A record pointing traffic to domain.com to Tumblr and feed.domain.com to the IP address of my choice? In other words, by setting up a naked domain A record to Tumblr's IP, will I inherently lose traffic to feed.domain.com? Can I write another A record for the specific subdomains I want to point to my server? I hope this makes sense.
