Resolved problems
The following problems have been corrected:
© 2016 Hitachi, Ltd. All rights reserved. 5
RN-93HSDP005-08 (May 2016)
In the following cases, operation is not guaranteed:
true is specified for the hsdp_restart property in the SDP manager
definition file.
The default value of the hsdp_restart_watch_time property in the SDP
manager definition file is changed.
The default value of the hsdp_retry_interval property in the SDP
manager definition file is changed.
If you executed the hsdpcql command with the -thread option with the
option argument of at least 2, and then started the external adaptor while the
query group is starting, the external adaptor does not send data to some
query groups.
The hsdpcdaset command cannot be executed when both the -host and -
port options are omitted.
If one cascading adaptor is connected to the same input stream and query
group of multiple working directories on the same host or if multiple
cascading adaptors are connected to the same input stream, the
hsdpstatusshow command outputs one of the following sets of items:
destination server cluster name
destination host name
destination adaptor name
destination query group name
destination stream name
adaptor connection status
Response from the hsdpcqlstart and hsdpcqlstop commands is delayed in a
scale-up configuration.
If the hsdpsetup command is executed with the -host option and with the
host name or IP address of a non-local host as the option argument, then the
hsdpstatusshow command outputs the operation information of the SDP
server on another host.
If the cascading adaptor receives a character string constant as the analysis
result from the stream data processing engine, the cascading adaptor sends
an empty string to the external output adaptor instead of the received string.
If an input stream contains one or more CHAR type columns, and the SELECT
clause selects the specified CHAR type column from the input stream, the
column of CHAR type is converted to the VARCHAR type.
From the SDP coordinator, the SDP broker searches for the stream of the
locked query group.
© 2016 Hitachi, Ltd. All rights reserved. 6
RN-93HSDP005-08 (May 2016)
The cascading adaptor does not connect to the SDP broker on the local host
under the following circumstances:
The hsdpsetup command is executed with the -host option and with the
host name or IP address of a non-local host as the option argument, and
the host name or IP address of the SDP broker is omitted in the
stream.output.stream-name.link property in the query group
properties file.
Two output streams are specified in the stream.output.stream-
name.link property in the query group properties file. The host name or
IP address of a SDP broker other than the local host is specified in the first
output stream, and is omitted in the second output stream.
If the hsdpsetup command is executed with the -host option and with the
host name or IP address of a non-local host as the option argument, the
hsdpstatusshow command outputs the KFHD92110-E message with an
incorrect host name or IP address of the SDP broker when it fails due to a
communication error with the SDP broker.
When one of the following statistical functions is called in a query, the
function inputs one or more tuples, and the number of the tuples that are
being processed by the function temporarily becomes zero, an error occurs in
the query group and the query group is locked up:
CORREL()
COVAR()
COVAR_POP()
STDDEV()
STDDEV_POP()
VAR()
VAR_POP()
Known problems
Restriction on this release
(1) In the following cases, operation is not guaranteed:
An invalid value is specified for a property in the following files:
Query group property file
SDP manager definition file
External adaptor definition file
Multiple internal adaptors open the same output stream.
© 2016 Hitachi, Ltd. All rights reserved. 7
RN-93HSDP005-08 (May 2016)
Multiple external adaptors open the same output stream.
An external adaptor opens one output stream through multiple registered
callbacks.
An HSDP file is named by using invalid characters.
Installation precautions
Installation
(1) Log on to the installation-target machine as a root user.
(2) Insert the installation medium.
If it is not mounted automatically, mount the directory manually.
(3) Change to the directory where the HSDP installer is placed:
# cd <CD-ROM-mount-directory>/HSDP/
(4) Execute the following command:
# install.sh
or
# install_runtime.sh
When the installation is complete, HSDP is installed in the following directory:
/opt/hitachi/hsdp/
Uninstallation
Prerequisites
(1) All SDP servers must be stopped.
Run the hsdpstatusshow command with no option specified, and then verify that
the SDP servers in all working directories have stopped.
(2) The SDP manager must be stopped.
Run the hsdpstatusshow command with no option specified, and then verify that
the SDP manager has stopped.
Procedure
(1) Log on to the target machine where you want to uninstall the software as a
root user.
(2) Execute the following command:
# /opt/hitachi/hsdp/uninstall/uninstall.sh
© 2016 Hitachi, Ltd. All rights reserved. 8
RN-93HSDP005-08 (May 2016)
Note:
Move to a directory other than /opt/hitachi/hsdp/ before executing the above
command.
Port numbers
Port numbers always used
HSDP Port number
Specify 8 ports beginning from the base port number as the -port argument of
the hsdpsetup command.
Port numbers conditionally used
To use the dashboard output connector:
Dashboard output connector port number
Specify the dashboardPortNo attribute of either
InprocessGroupDefinition tag
or
RMIGroupDefinition tag
in the adaptor composition definition file, or 20421 by default.
Usage precautions
Notes on the virtualization platform environment
This product design was based on a standard environment (an OS environment
on an actual machine). In a virtualization platform environment, this product may
behave differently from a standard environment due to the effect of virtualization
on hardware resources, deteriorating performance caused by shared I/O, or other
causes. Use this product after you have accepted the following conditions for use:
Usage conditions
This product has been verified to ensure that it operates without error. However,
performance deterioration can occur. In addition, functions such as those to
obtain CPU times might be adversely affected. For this reason, in order to use
this product in a virtualization platform environment, you must conduct a full
operation evaluation and performance verification of the system. Perform these
checks after the system has been built, and confirm that it uses the appropriate
hardware, virtualization software, guest OS, this product, and applications.

In the above case and other failure cases, if a process of a component
does not start in the monitoring period after failure of the restart request,
the SDP manager determines that the process is down and retries the
restart request.
If the SDP manager detected that a process of a component is down three
times within the time set for the hsdp_restart_watch_time property in
the SDP manager-definition file, the SDP manager stops monitoring the
component. After that, the SDP manager does not attempt to restart the
component. The SDP manager continues monitoring other components.
