Resolved problems

The following problems have been corrected:


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.


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.


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


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.

If a shutdown process fails to restart even after the restart request has

attempting to restart the component and starts monitoring other

components.

[Text after change]

If an inter-process connection failure occurs even after a restart request

has run for the specified number of times, the restart request fails.

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
