OBIEE Cache Purge in Unix Environment

Question

Hi,
We are trying to purge OBIEE cache using unix shell script and purgecache.txt which contains call to SAPurgeAllCache().
We are using below script
export MW_HOME=/qa/middleware/
. $MW_HOME/instances/instance1/bifoundation/OracleBIApplication/coreapplication/setup/bi-init.sh
$MW_HOME/Oracle_BI1/bifoundation/server/bin/nqcmd -d AnalyticsWeb -u weblogic -p weblogic1 -s /users/home/test/purgecache.txt
We are gettting below error message After executing script
/qa/middleware/instances/instance1/tmp/OracleBIODBCComponent/coreapplication_obiodbc1/obis_temp is not a valid Oracle BItemp directory path
is it required to call sa-init64.sh ?? Are we missing anything?? What could be another way to purge cache from command line?
# it is required to run bi-init.sh (UNIX) or bi-init.bat before launching any command line utilities. This sets the environment variables like ORACLE_HOME and ORACLE_INSTANCE correctly. We have used it.
# Commented sa-init64.sh
# as it is giving below error
# syntax error at line 7: `(' unexpected
Thanks in advance

You can try this
Create a text file with a name e.g: say purgecache.txt with below code in it
Call SAPurgeAllCache() and save the file in /<MW_HOME>/Oracle_BI1/bifoundation/server/bin directory.
Before running nqcmd, you must first run bi-init.cmd (or bi-init.sh on UNIX) to launch a command prompt or shell window that is initialized to your Oracle instance. You can find this utility in:
<MW_HOME>/ORACLE_INSTANCE/bifoundation/OracleBIApplication/coreapplication/setup
Then, run nqcmd from the resulting shell window with the desired options.
For example:
nqcmd –d my_dsn –u my_username [-p my_password] –s sql_input_file –o my_result_file
You can pass a text file with SQL statements to the utility (script mode), or you can enter SQL at the command line (interactive mode). Queries are run against the default subject area, unless the object names used in the query are fully qualified.
For example to purge BI Server cache run below command
In windows:
nqcmd -d AnalyticsWeb -u <weblogic_admin user> -p <weblogic_admin password>-s purgecache.txt
In Unix:
./nqcmd -d AnalyticsWeb -u <weblogic_admin user> -p <weblogic_admin password>-s purgecache.txt
