$ arsdb -u -I PROD arsdb: ARS4013E Unable to determine the database engine
Check to see that your ars.ini configuration parameters are correct and up to date. On some platforms, the values (especially User ID's) are case-sensitive, so you may need to use "archive" instead of "ARCHIVE".
Ensure that the ARS_DB_ENGINE parameter in the ars.cfg file is one of the three following values: DB2, ORACLE, MSSQL.
If you have a non-default CMOD instance name ("archive") then you **MUST** use the -I parameter with the correct IBM Content Manager OnDemand instance name.
Check to see that you have DB2 connectivity from the IBM CMOD instance owner account, and permission to access the tables:
# Can I run db2 and see the database directory? $ db2 list database directory System Database Directory Number of entries in the directory = 1 Database 1 entry: Database alias = ARCHIVE Database name = ARCHIVE Local database directory = /arsdb/SMS Database release level = 10.00 Comment =
# Do I have permission to connect to the database? $ db2 connect to BNC Database Connection Information Database server = DB2/LINUXX8664 10.5.8 SQL authorization ID = ARCHIVE Local database alias = ARCHIVE
If you're not able to see or connect to DB2, make sure you have the correct group membership (sysadm1 if your IBM CMOD installation was by-the-book), and check to make sure that the appropriate db2 links have been created with the
db2ln command. You will need administrative or root access to perform this task.
Also check to see that you have the correct environment variables, with the
setenv commands, depending on your command shell:
$ set DATABASE=ARCHIVE DB2DIR=/opt/ibm/db2/V10.5 DB2INSTANCE=archive DB2LIB=/home/archive/sqllib/lib DB2_HOME=/home/archive/sqllib DB2_NET_CLIENT_PATH= HOSTNAME=OnDemand.example.com HOSTTYPE=x86_64 IBM_DB_DIR=/home/archive/sqllib IBM_DB_HOME=/home/archive/sqllib IBM_DB_INCLUDE=/home/archive/sqllib/include IBM_DB_LIB=/home/archive/sqllib/lib
If you don't have these values, you will need to find the
db2profile script and execute it to set these variables -- it can be found inside the 'sqllib' directory of the database owner's home directory.
Finally, IBM CMOD updates have been known to have problems co-existing with prior versions of Content Manager OnDemand being installed at the same time. Removing old Content Manager OnDemand versions before configuring your newly-installed instance with the
uninstallod command may help eliminate this error. Make sure to back up your configuration files first!
