Windows Installation for Java

This page explains all the steps required to install the NCache Java Edition in Windows.

Install NCache for Java Edition

NCache Java Edition installation occurs via an interactive setup wizard by following these steps:

• Search for Command Prompt in the Windows Start menu. Right-click on the search result Command Prompt and select Run as Administrator as NCache must install with permission from an admin user.

• Install NCache: To install NCache you need to download .msi file from NCache Download Center and run it from Command Prompt using the command below. Please note that the .msi file may have a different name for the .NET Framework installation.

msiexec.exe /I "C:\NCacheSetuPath\ncache.ent.java.x64.msi"

• The following Welcome to the NCache Setup Wizard screen appears:

• Click Next.

• The next screen asks you to accept the license agreement.

• By clicking I accept the terms in the License Agreement, you are making a legal commitment to abide by the Alachisoft Software Agreement for NCache. You cannot proceed without accepting the license agreement.

• Click Next.

• The Select NCache Installation Type screen appears. Select the required installation and click Next.

• The installer auto-detects the Java's installation directory. If multiple Java versions exist on the system or JAVA_HOME is misconfigured, you'll need to manually enter the Java 17 installation path.

• The Installation Key screen appears, asking for the installation key.

The Installation Key screen only appears for the Cache Server installation type.

• This is the key you receive from Alachisoft Support when you register to download NCache Enterprise.

Enter all the required information and choose to Register or Log in before receiving an installation key via email. Enter that installation key in the above box and click Next.

  • NIC binding binding in case of multiple server IP addresses.
  • Configure NCache-specific ports in case of a firewall.

• From the dropdown menu, select the IP address you want to bind NCache services.

• By default, the firewall configures for all ports used by NCache. Disable the checkbox if you don't want to configure NCache ports with the firewall.

• Click Next.
  

• The next screen asks for user credentials with administrative privileges required to monitor PerfMon counters. Enter the account name and password, or use a local system account. Click on Next.

• By default, the NCache Service will create and start a demo cache named demoCache of topology Partition-Replica at the end of setup installation. You can disable this option from this screen by unchecking the "Start demo cache at the end of the process" option. Click on Install when done.

• After the installation is successful, the following screen is displayed. On this screen, there is an option to Launch the NCache Management Center which automatically launches the NCache Management Center at http://localhost:8251 after successful installation. Alternatively, you can choose the option to Launch the Getting Started Guide. After you have made your choice, click Finish.

• If you have used an expired installation key, you will get this screen instead of the exit installation screen:

• If you have a license key or extension key, you don't need to worry about this message. Use the Register NCache script to activate your license or extend your evaluation period. Otherwise, contact Alachisoft Sales to purchase an NCache license or extend your evaluation.

• You can refer to the Getting Started Guide to set up the NCache environment.

Installation Options for Java Edition

When setting up NCache in your environment, it's important to select the right installation type based on your particular requirements. NCache offers four different installation options, the following sections details these.

Cache Server

This option installs both the server and client portions of the NCache software. We recommend you install it on 2 or more servers for reliability - these can be dedicated servers or your web/app servers with a dedicated caching tier for 3 or more web/app server environments. Usually, we recommend a 4:1 or 5:1 ratio between web/app servers and cache servers. If you’re installing an NCache server on web/app servers, ensure you have sufficient memory and CPU power available for application and NCache.

Developer/QA

This option installs the NCache API, online help/documentation, and a local stand-alone cache. Note the following limitations for the Developer/QA Installation, while connecting to remote caches:

• Only 2 remote clients can connect to the local cache on the Developer/QA machine. However, you can connect with as many local clients as you want.
• Only 3 caches can run on the Developer/QA machine with a maximum combined size of 2GB.
• The total number of requests/second per local cache is 25.
• To add a client, the user must add the relevant configuration manually in the client.ncconf. The Developer/QA installation provides no support for command line or web-based tools.
• All clients licensed under Developer/QA license cannot make more than 100 requests/sec to the remote cache.
• There is a limited number of requests (200,000) a client can send to the remote cache. For instance, in the lifetime of a client application, if it is licensed with a Developer/QA license, the client will stop making requests to the remote cache after it has sent 200,000 previous requests to the same destination. The only workaround is to restart the application for another 200,000 requests. Once the client has made 200,000 requests, a licensing exception will occur saying “Clients running under a Developer/QA license cannot send more than 200,000 requests to the remote cache.”

Remote Client (Optional)

This option installs NCache on all web/app servers from where you want remote access to the cache servers. You are only required to install the Remote client if you want to have the following benefits:

• Install OutProc Client Cache.
• Client Monitoring from within NCache Monitoring.
• Client Management through Management Center.
• Client/Server Licensing.
