Maintenance Mode - OBIEE

Maintenance Mode is used for administration of Presentation Services. When Maintenance Mode is turned ON, users will not be able to save changes in Presentation Catalog- it goes in to a read-only mode at this point. This will make sure that webcat is consistent and no one is making changes to reports or saving new ones while you do your maintenance activities.

Set Minimum Length for Passwords

When we create a Repository, Administrator account will be the default account with no password and we can create as many user accounts we need. By default Administrator will not be having any password. We have to set password for user accounts, there is no restriction on password length, i.e password may contain any number of characters.

We can set the minimum length for passwords in the NQSConfig.INI file using the MINIMUM_PASSWORD_LENGTH setting.

By default, value of MINIMUM_PASSWORD_LENGTH is 0.

If you want the minimum length for password is 5, then set MINIMUM_PASSWORD_LENGTH = 5. 

Note : ensure that the existing passwords length must be greater than and equal to 5. Otherwise login will be failed. So before changing the value for MINIMUM_PASSWORD_LENGTH, make sure that all passwords length is more than or equal to that value.

ERROR 1064 on OBIEE.

Today I came across this error when I tried to restart the Oracle BI Server on my local system. The actual error I got is-

Could not start Oracle BI server service on Local system.

Error 1064 : An exception occurred in the service when handling the control request.

After searching some blogs I got the solution for this issue.

Solution  :

Open NQSConfig.INI  file, and check  each  section and make necessary changes.

In my case, I had given the wrong repository name (instead of text.rpd I had given tex.rpd), so I changed the name of the RPD, after that restart was successfull.
