• OSI protocol
  HiRDB Dataextractor supports only the TCP/IP protocol; it does not support the OSI protocol.
  

• LANG
  If you omit the LANG environment variable, HiRDB Dataextractor assumes ja_JP.eucJP.
  
• LD_LIBRARY_PATH
  When you use the xtrep command to extract and import HiRDB data, specify the absolute path of the directory containing the extracting HiRDB's common library in the user environment where the xtrep command is entered. Use this environment variable instead of the existing SHLIB_PATH environment variable.
  

• When XDM/XT is linked to extract data from HiRDB or to import data into HiRDB, the character code set specified in the LANG environment variable must be the same as the character type specified in the CONVERT XDM/XT control statement. If they are not the same, the results may not be correct.
• If the null value information file is omitted, HiRDB Dataextractor assumes ## (SJIS codes X'81948194') as the default null value for the NCHAR and NVARCHAR attributes. If you omit the LANG environment variable or specify ja_JP.eucJP, ja_JP, or ja_JP.ujis as its value, the data ## on the extracting HiRDB will not be stored as the null value by the importing HiRDB. To import ## data as the null value, specify ## in UJIS codes as a literal in the null value information file. For details about how to specify a null value information file, see 4.2.4 Contents of files specified with the xtrep command.
• If you specify SPACE for a column with the NCHAR or NVARCHAR attribute in the null value information file, HiRDB Dataextractor uses a space (SJIS code X'8140') as the default null value. Therefore, if you omit the LANG environment variable or specify ja_JP.eucJP, ja_JP, or ja_JP.ujis as its value, blank data on the extracting HiRDB will not be stored as the null value by the importing HiRDB. To import a space as the null value, specify the space in its UJIS code as a literal in the null value information file. For details about how to specify a null value information file, see 4.2.4 Contents of files specified with the xtrep command.

This item describes a setup file for using HiRDB Dataextractor that has different settings from the normal settings.

If you use RedHat 7 or later, use the following inetd configuration file:

/etc/xinetd.d/xxxx

xxxx: Create the file using the service name registered in the /etc/services file.

(a) Contents

This file sets up the startup of HiRDB Dataextractor.

(b) Examples

• If the service name is hxt000, the file name would be /etc/xinetd.d/hxt000.

Example 1: Definition for starting HiRDB Dataextractor

 
# HiRDB Dataextractor
service hxt000
{
  disable       = no
  socket_type   = stream
  wait          = no
  user          = root
  server        = /opt/HIRDBXT/bin/pxtcntl
  server_args   = /opt/HIRDBXT/conf/xtenv0
}
 

Example 2: Definition for starting HiRDB Dataextractor with environment variables specified

 
# HiRDB Dataextractor
service hxt000
{
  disable       = no
  socket_type   = stream
  wait          = no
  user          = root
  server        = /usr/bin/env
  server_args   = XTLOGNAME=XTLOG /opt/HIRDBXT/bin/pxtcntl /opt/HIRDBXT/conf/xtenv0
}
 

Note: If you have added or modified files, make sure that you restart xinetd with the following command:

 
/etc/rc.d/init.d/xinetd restart
