Upgrading the First Platform Server to the HA Cluster
When you upgrade the first Platform Server to the HA cluster, follow a procedure based on the approach you choose:
Make sure you know the IP Name of the primary and secondary Platform Servers. The first Platform Server migrated to the HA Cluster should be the primary Platform Server.
Approach 1: Copying Log and Transnum Files
Procedure
|
1.
|
Run the install script or the hainstall to convert to HA mode, indicate your PS machine as a primary one. |
|
2.
|
Manually copy or move log files from old log folder to a new one on the shared drive. |
|
3.
|
If you are installing TIBCO MFT Platform Server 8.1.1 over an existing version, the config files and transnum file are copied to the common HA config directory. |
|
4.
|
If you re installing a brand new TIBCO MFT Platform Server 8.1.1, the default config files and transnum file are copied to the common HA config directory. |
|
5.
|
If you are installing TIBCO MFT Platform Server 8.1.1 in a directory different from your existing Platform Server, you should manually copy the config files to the common HA config directory. Otherwise, you have only a default configuration files in the common HA folder. You should also manually copy or move the old transnum file to a new trn folder on a shared drive. |
|
6.
|
You do not need to change any Collection setting on Command Center Server definition side, unless you plan to use the Load Balancer (LB) which is in front of this new Platform Server running in HA Mode. If you plan to use LB with your new HA cluster, then reconfigure the Command Center Server definition to point to the IP name and port of the LB. |
Approach 2: Resetting the Collection History
Before migrating to HA mode, make sure that all platform transfer records have been collected by Command Center.
Procedure
|
1.
|
Stop the old version of TIBCO MFT Platform Server. |
|
2.
|
Run the install script or the hainstall to convert to HA mode, indicate your PS machine as the primary one. |
|
3.
|
If you are installing TIBCO MFT Platform Server 8.1.1 over an existing version, the config files and transnum file are copied to the common HA config directory. |
|
4.
|
If you are installing a brand new TIBCO MFT Platform Server 8.1.1, the default config files and transnum file are copied to the common HA config directory. |
|
5.
|
If you are installing TIBCO MFT Platform Server 8.1.1 in a directory different from your existing Platform Server, you should manually copy the config files to the common HA config directory. Otherwise, you must have only a default configuration file in the common HA folder. You must also manually copy or move the old transnum file to a new trn folder on a shared drive. |
|
6.
|
If you want to use the Load Balancer (LB) with your new HA cluster, then re-configure the Command Center Server definition to point to the IP name and port of the LB. Also, you must select the Reset Collection History check box. Or, if you do not plan to use LB with your new HA cluster, then the only thing you must do on the Command Center Server definition is to clear the Reset Collection History check box. |
After your first Platform Server is migrated to HA mode, you can add other Platform Servers to the HA Cluster by running the install
or the hainstall
script on those machines. However, do not designate the new Platform Servers as a “Primary”. Their existing configuration files are not used in HA mode. If you do not want to lose transaction history from those machines, make sure that all log records are collected by Command Center Collector before HA migration.
