When you are removing a node from a cluster, use the SearchService.removeIndexingNode
wsadmin command to remove the node from the index management table.
Before you begin
You must remove the node from the cluster before using the
SearchService.removeIndexingNode command to remove it from the index
management table. For information about how to remove nodes, see Removing
nodes from a cluster.To use the SearchService.removeIndexingNode
command, you must use the IBM® WebSphere® Application Server
wsadmin client. See Starting
the wsadmin client for details.
About this task
You can use the removeIndexNode command to remove an entry
from the SR_INDEX_MANAGEMENT table that is added or updated by Search
servers at start-up time.Procedure
To remove a node from the index management table, complete
the following steps.
- Start the wsadmin client from the following
directory of the system on which you installed the Deployment Manager:
app_server_root\profiles\dm_profile_root\bin
where app_server_root is
the WebSphere Application
Server installation directory and dm_profile_root is
the Deployment Manager profile directory, typically dmgr01.You
must start the client from this directory or subsequent commands that
you enter do not execute correctly.
- After the wsadmin command environment
has initialized, enter the following command to initialize the Search
environment and start the Search script interpreter:
execfile("searchAdmin.py")
If prompted to specify a service to connect to, type 1 to pick
the first node in the list. Most commands can run on any node. If
the command writes or reads information to or from a file using a
local file path, you must pick the node where the file is stored.When
the command is run successfully, the following message displays:
Search Administration initialized
- Use the following command:
- SearchService.removeIndexingNode(String nodeName)
Removes the specified node from the index management table.
This
command takes a single argument:
- nodeName. The name of the node to be removed. This argument is a string value that takes the
following format:
nodeName:serverName
To
retrieve a list of the indexing nodes in your deployment, run the SearchService.listIndexingNodes()
command. For more information, see Listing indexing nodes.
For example:
SearchService.removeIndexingNode("Node01:cluster1_server1")
When
the command runs successfully, 1 is printed to the wsadmin console.
If the command does not run successfully, 0 is printed to the wsadmin
console.
