OBIEE: Date Difference Excluding Weekends

We need to calculate the difference between two dates excluding weekends. Here we have considered Friday and Saturday as weekends.

We can create a function in database which can be used to do the same job.

 CREATE OR REPLACE Function WORKINGDAY( DATE1 IN DATE,DATE2 IN DATE )
   RETURN number
IS
   workingday number;
 
BEGIN

  select (CASE WHEN (COUNT(ROW_WID)-1)<0 then COUNT(ROW_WID) else COUNT(ROW_WID)-1 end) INTO workingday
 from w_day_d where   CALENDAR_DATE between DATE1 and DATE2
 AND  DAY_NAME NOT IN ('Friday','Saturday');

RETURN workingday;
END;

We can call this PL/SQL function in OBIEE report.

EVALUATE('WORKINGDAY(%1,%2)' as double, DATE1,DATE2)


Stay well and enjoy !!

OBIEE Out of Disk Space

Error Details

Error Codes: AAD5E5X3:OPR4ONWY:U9IM8TAC
Odbc driver returned an error (SQLFetchScroll).
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 46118] Out of disk space. (HY000)

We can overcome this issue by clearing up some cache files. 

1) WebLogic Server Log Files

Check your Admin and Managed server log directories and remove any old log files that you no longer exist:

[Middleware Home]/user_projects/domains/bifoundation_domain/servers/bi_server1/logs
[Middleware Home]/user_projects/domains/bifoundation_domain/servers/AdminServer/logs

2) Oracle BI System Log Files

Check all the sub-folders underneath the following directory and remove any old .log files:

[Middleware Home]/instances/bi_instance/diagnostics/logs

3) Oracle BI "tmp" Folder for Cache Entries

If an Oracle BI process dies unexpectedly for any reason it mean that tmp and cache files do not get cleared up.   So check all the folders and sub-folders in the following location and remove any old files:

[Middleware Home]/instances/bi_instance/tmp

4) Core Dump Files

Some processes will create core dump files/folders to be created if they ever die unexpectedly.     So it would be worth removing any "core_" files and folders which exist in the following locaiton:

[Middleware Home]/instances/bi_instance

5) Oracle BI Patch Files

After you have applied a patch to Oracle BI 11g, you can remove the extracted patch folders once they have been applied.   The patch files would have probably been extracted into sub-folders within the following locations:

[Middlware Home]/Oracle_BI1                   e.g. /app/oracle/middleware/Oracle_BI1/7843472

[Middlware Home]/Oracle_common

If issue still not resolved then we can change the workdirectory to the new mount point in NQSconfig.ini and restart the services.
