Replicated Caching

Why use shared cache?

There is no more efficient way to increase the scalable performance of applications then the use caching to unload deeper layers.

Server configuration for replicated caching

In Shared Cache Topology section we have listed advanteges of replicated caching. Lets assume we have 3 IIS WebServers in the same zone and we want to configure them for replicated caching where on each server an instance of indeXus.Net Shared Cache Server is installed.

Server details:

Server no. 1	Server no. 2	Server no. 3
Name: WebSrv20 IP: 192.168.1.20	Name: WebSrv30 IP: 192.168.1.30	Name: WebSrv40 IP: 192.168.1.40

Example of a replicated server configuration file

The following configuration fits for server no: 1.

Notice: The most important thing is that you add your server nodes and set ServiceFamiliyMode="1" to enable replication. If you only configure the replicatedServers will be not enough and will not work without to enable familiy mode.

<replicatedSharedCache defaultProvider="ServerSharedCacheProvider">

    <serverSetting

        ServiceCacheIpAddress="127.0.0.1"

        ServiceCacheIpPort="48888"

        SharedCacheVersionNumber="2.0.3.268"

        LoggingEnable="1"

        ServiceFamilyMode="1"

        CacheAmountOfObjects="200"

        CacheAmountFillFactorInPercentage="90"

        ServiceCacheCleanup="LRU"

        ServiceCacheCleanupThreadJob="1"

        TcpServerMaxThreadToSet="-1"

        TcpServerMinThreadToSet="-1"

/>

<replicatedServers>

    <add key="WebSrv30" ipaddress="192.168.1.30" port="48888" />

    <add key="WebSrv40" ipaddress="192.168.1.40" port="48888" />

</replicatedServers>

<providers>

    <add

    name="ServerSharedCacheProvider"

    type=">

MergeSystem.Indexus.WinServiceCommon.Provider.

Server.IndexusServerSharedCacheProvider,

MergeSystem.Indexus.WinServiceCommon"

    </add>

</providers>

</replicatedSharedCache>

For the other 2 server nodes you alwasy take the 2 other servers which you add to replicatedServers.

Server node no. 2:

<replicatedServers>

    <add key="WebSrv20" ipaddress="192.168.1.20" port="48888" />

    <add key="WebSrv40" ipaddress="192.168.1.40" port="48888" />

</replicatedServers>

Server node no. 3:

<replicatedServers>

    <add key="WebSrv20" ipaddress="192.168.1.20" port="48888" />

    <add key="WebSrv30" ipaddress="192.168.1.30" port="48888" />

</replicatedServers>
