Reporting Services requirements
Reporting Services has requirements in addition to the primary Jazz™ for Service Management requirements.
- New Features
- Reporting Services is available as an IBM® Installation Manager offering.
- Supported IBM Installation Manager Versions are 1.7 and above
- IBM WebSphere® Application Server Version 8.5.5.4 is available for deployment.
- localhost network address resolution
- Ensure that your localhost network address resolves to 127.0.0.1 during the installation. To do this, edit the /etc/hosts file to contain 127.0.0.1 localhost.
- Separate logging ports for multiple Reporting Services instances
- Reporting Services uses
the 9362 port as the default
port for logging. If you want to install Reporting Services on
a machine that already has an earlier version of Reporting Services installed,
you must change the logging port of the existing installation; otherwise
a logging port conflict occurs if the existing installation already
uses the default port.To change the logging port for the existing installation:
- Open a command window and change to the c10_location/bin64 directory in the existing Reporting Services installation.
- Run the following command to open IBM Cognos® Configuration:
- tcr_cogconfig.bat
- tcr_cogconfig.sh
- Select . The Logging panel opens.
- In the Local log server port number field, change the value from 9362 to an available port number. See Change a Port or URI Setting in the IBM Cognos Business Intelligence Information Center.
- Ulimit settings
- Reporting Services requires
that the following settings are applied in the target environment:
- Ulimit Stack set to 2048 or greater
- Max user processes limit set to 256000 or greater
- Open files limit set to 32768 or greater
- Review the current values for the settings by using the ulimit command:
- ulimit -n
- The maximum number of open file descriptors.
- ulimit -s
- The maximum stack size.
- ulimit-u
- The maximum number of processes available to a single user.
- Change the settings only if your current values are lower than
the minimum values required by Reporting Services,
for example:
- To change the open file limits, change the value for the nofiles parameter to 32768 in
the /etc/security/limits file; alternatively,
run the following command:
chuser nofiles= 32768 user_id
- To change the maximum stack size, change the value for the stack property to 2048 in the /etc/security/limits file.
- To change the maximum processes per user, running the following
command:
chdev -1 sys0 -a maxuproc='256000'
- To change the open file limits, change the value for the nofiles parameter to 32768 in
the /etc/security/limits file; alternatively,
run the following command:
- Ulimit settings
- Reporting Services requires
that the following settings are applied in the target environment.
- Maximum user processes limit set to 256000 or greater
- Open files limit set to 32768 or greater
- Limit Stack set to 2048 or greater
- Review the current values for the settings by using the ulimit command:
- ulimit -n
- The maximum number of open file descriptors.
- ulimit -u
- The maximum number of processes available to a single user.
- ulimit -s
- The maximum stack size.
- Change the settings only if your current values are lower than
the minimum values required by Reporting Services,
for example:
- ulimit -n 32768
- Changes the open file limits to 32768.
- ulimit -u 256000
- Changes the maximum number of processes available to a single user to 256000.
- ulimit -s 2048
- Changes the maximum stack size to 2048.
Important: By running the command, you change the settings for the current session only. You can configure the open file limits globally. Open the /etc/security/limits.conf file and add the following line: * hard unfile 2048.
- Ensure that you have administrative privileges, that is, you must be an Administrator or belong to the Administrators group.
