Couple of OpenWorks variables

hollyghozi — Wed, 12 Aug 2009 13:46:34 +0000

Today, I’ve learned two OpenWorks environment variables.
1. OW_DEFAULT_DISTRICT
You will have to set the value of this environment variable, if you want to set the default DISTRICT.

export OW_DEFAULT_DISTRICT=OWSIDEAST

After you set the variable, then start your OpenWorks > Project Status, you’ll see the DISTRICT already been choosen.

2. OW_ADMIN_UTILS_PW
You will need to set the value of this environment variable, if you change the password of OW_ADMIN_UTILS.

export OW_ADMIN_UTILS_PW=owadminutilspassword

OpenWorks: Create default Wallet

As addition to the OpenWorks: OS Authentication in R5000. You can create default wallet without having to login into OpenWorks by running the script below.

Before you run the script, you have to make sure that the following environment variable is populated correctly:
OWHOME OWSYSSID ORACLE_HOME OW_HOME_DIR

From your linux shell, please run the following:
Bash$ ${OWHOME}/jre/bin/java \ -classpath ${OWHOME}/jar/com_lgc_ow_devkit.jar \ com.lgc.ow.credentials.OracleWallet \ ${OWSYSSID} ${ORACLE_HOME} ${OW_HOME_DIR}

If it’s not exist, it will create ${HOME}/wallet directory with user and password entry. The password created by the script has to be equal as the user. If you have different password value, you’ll need to use the default OpenWorks user dialog.

OpenWorks: OS Authentication in R5000

OpenWorks R2003 use traditional external user as the authentication. By simply, creating user via sqlplus:
create user osuser identified externally
And you can connect to OpenWorks Oracle database by:
sqlplus /@openworksdb

In R5000, end user is still able to logon without password but the method is slightly different. R5000 uses Oracle Secure External Password Store. There’s a good tutorial on this created by oracle-base.com.

The wallet directory is set by ${OW_HOME_DIR} environment variable. By default the value is equal as ${HOME}. You would see wallet directory in your home directory. So, if your R5000 environment is set correctly, you will able to do:
sqlplus /@openworksdb

OpenWorks: Create interpretation project failed (2)

In addition to my post earliear, there’s something else that we can do to minimize the error:
chmod -R o+rx $ORACLE_HOME
By make sure everyone has access to the Oracle’s library and executable, it’ll enable the user to create the Interpretation project.

OpenWorks: Create interpretation project failed

Holly — Tue, 13 Jan 2009 22:38:09 +0000

It’s failed when creating interpretation project in OpenWorks R5000. The error message says:

Create interpretation project failed:
Failed to insert information in project PROJECTNAME using
begin
PROJECTNAME.ow_prj_utils_pkg.ow_store_password(?,?,);
end;

The ow_prj_utils_pkg.ow_store_password will call java store procedure. This java store procedure is loaded into interpretation project. To load java class into database, OpenWorks will call loadjava utility. The loadjava is oracle utility.

To fix this issue, you have to make sure that you correctly install Oracle 10g.
1. Check the $ORACLE_HOME
2. Make sure loadjava is in your $PATH, check with which loadjava
3. Check the content by calling: more loadjava
