This command creates a Text Extender instance.

Authorization

Command syntax

For UNIX:

>>-txicrt--instance-name--db2-instance-name--------------------->
 
>-----+----------------------------+---------------------------->
      '-port-start--+-----------+--'
                    '-port-end--'
 
>-----+-----------------------+---+-----------+----------------><
      '- -nodes--identifiers--'   '- -client--'
 

For Windows NT:

>>-txicrt--db2-instance-name----+----------------------------+-->
                                '-port-start--+-----------+--'
                                              '-port-end--'
 
>-----+-----------------------+---+-----------+----------------><
      '- -nodes--identifiers--'   '- -client--'
 

Command parameters

instance-name
(UNIX only) The user ID of the instance owner.

db2-instance-name
The name of the DB2 instance to be associated with the instance being created.

port-start/port-end
The TCP/IP port range to be used if you are working with more than one physical node. Not required if you are using only logical nodes.

The port range must be equal to the number of nodes you want to work on. If you are working with one node, specify only a port-start parameter. To support a subset of nodes, use the port-last parameter.

Do not specify a port range if the instance is created on a single-partition database.

Use only port numbers that are not already listed in the TCP/IP etc/services file. Do not specify port numbers for client-only installations.

-nodes identifiers
A list of node identifiers. Example: -nodes 0 1 2.

Use this parameter if your table belongs to specific nodes in a nodegroup.

If this parameter is not specified, all nodes are used, that is, all the nodes defined in db2nodes.cfg.

Do not specify node identifiers for client-only installations.

-client

Specify this parameter if you have a Text Extender client-only installation. If you do not specify this parameter, TXICRT configures a client/server instance of Text Extender.

Usage notes

Enabling text tables or columns is possible only on nodes where you have created a Text Extender instance.

A DB2 instance must already have been created for the user ID.

In UNIX installations, this instance-specific command is in the /usr/lpp/db2tx_05_02/instance directory.
