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 Environment > Logging. 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'
```

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.
