Zero Based Budgeting (ZBB) Considerations within Hyperion Planning

Zero based budgeting (ZBB) applications are becoming increasingly popular as a way to develop a budget, especially for lower growth organizations that are interested in cutting costs. The most significant difference between ZBB applications and traditional budget applications are the level of details captured. Where traditional budgeting applications plan an expense item directly or using a price X quantity formula, ZBB applications will plan every line item related to that expense. For example, when budgeting supply expenses, a ZBB application will include values for each detailed line item, including pencils, pens, paper clips, etc. Given the level of detail required for ZBB applications, careful consideration needs to be taken in order to have optimal performance within Hyperion Planning

EPM 11.1.2.x - Binding Host Name to have Essbase bind only to the IP address

Specify a Binding Host Name to have Essbase bind only to the IP address for the specified Binding Host Name. Otherwise, at startup, Essbase binds on all available IP addresses.

In EPM 11.1.2.2 / 11.1.2.3 releases, use "ESSBASESERVERHOSTNAME server_name" that identifies the host where your Essbase application process runs. The value must be a valid host name and must map to an IP address assigned to the computer. If ESSBASESERVERHOSTNAME is not specified in essbase.cfg, Essbase and the applications listen on all interfaces (IP_ANY).

For details on this refer to Essbase Tech Ref

In EPM 11.1.2.4 release, in Configure Essbase Server specifies the host name (in Binding Host Name field) to which Essbase Agent and Essbase Server bind and where an Essbase application process runs.

For details refer to http://docs.oracle.com/cd/E57185_01/epm.1112/epm_install/essbaseAgentPortPanel.html

Adding trim functions to the column expressions in ODI

When OBIA adaptors extracts data from PSFT source, the data can be padded with spaces. The PSFT system stores the data in db with padded spaces and when it is taken across OBIA warehouse without applying trim function in the ODI maps, the warehouse will also have the data with padded spaces. Blog gives an example of how to fix these type of issues at the implementation time.

For VM guest (DomU) VIF interface, by increasing the Send Queue Length (txqueuelen) from 32 or 500 to 10000 can increase network performance 50%.

a. How to Increase Send Queue Length in Dom0:

In Dom0, you need to perform following permanent changes to make the txqueuelen to 10000:
1. Run below ifconfig script by crontab and it will automatically set 10000 for all the VIFs:
ifconfig | grep -P '^vif\d+\.\d+' |  awk '{system("ifconfig "$1" txqueuelen 10000")}'

2. Edit /etc/rc.local and append the following setting per interface:
ifconfig eth0 txqueuelen 10000
ifconfig eth1 txqueuelen 10000

3. It is recommended to perform sanity check that txqueuelen is set to 10000 for all the VIFs in Dom0 when VM guest (DomU) is restarted.

b. How to Increase Send Queue Length in VM Guest (DomU):

In VM guest (DomU), you need to perform following permanent changes to make the txqueuelen 10000:
1. Edit /etc/rc.local and append the following setting eth0 interface only:

OBIEE 11.1.1 - In case of Firewalls, OBIEE Scheduler may fails to Restart via OPMN or during BI configuration

Issue:

If you have Firewall between OBIEE Server and Oracle Database machine, the OBIEE Scheduler component may fails to restart via OPMN or during BI configuration.

Workaround:
The firewall is setup with 'Urgent Flag'. As per firewall documentation, the Urgent Flag cannot be disabled. It is a global setting and would affect all traffic going in and out in organization. So the issue can be resolved by setting DISABLE_OOB=ON in the SQLNET.ora for BI Scheduler.

The firewall is clearing this Urgent Bit in the communication, the message is not transferred from the Scheduler (DB Client) to the Oracle database so by setting DISABLE_OOB=ON the Urgent flag is not sent from Scheduler and the connection works normally.

How-to: On BIServer side only, set DISABLE_OOB=ON in SQLNET.ora file > …/Oracle_BI1/network/admin
