Upgrading to 0.21.0 and beyond from a pre-0.21.0 version

This procedure has to be done always as long as your database contains at least one entity document.

  • Stop contextBroker

  • Remove previous contextBroker version

    yum remove contextBroker 

  • Take a backup of your DBs (this is just a safety measure in the case some problem occurs, e.g some script gets interrupted before finished and your database data ends in a incoherent status)

  • Download the following scripts:

  • Install pymongo (it is a script dependency) in the case you haven't it previously installed

    pip-python install pymongo

  • Apply the fix_location_gjson.py to your DBs, using the following (where 'db' is the database name). Note that if you are using multitenant/multiservice you need to apply the procedure to each per-tenant/service database. The script can take a while, an interactive progress counter is shown.

    python fix_location_gjson.py orion

  • If you get the following message, there is some problem that needs to be solved before going to the next step. Check the Troubleshooting section below.

    WARNING: some problem was found during the process.

  • Apply the attrsvector2attrsobject.py to your DBs, using the following (where 'db' is the database name). Note that if you are using multitenant/multiservice you need to apply the procedure to each per-tenant/service database. The script can take a while, an interactive progress counter is shown.

    python attrsvector2attrsobject.py orion

  • If you get the following message, there is some problem that needs to be solved before going to the next step. Check the Troubleshooting section below.

    WARNING: some problem was found during the process.

  • Install new contextBroker version (Sometimes the commands fails due to yum cache. In that case, run "yum clean all" and try again)

    yum install contextBroker

  • Start contextBroker

Note that the rpm command demand superuser privileges, so you have to run them as root or using the sudo command.

Troubleshooting

Two different kind of problems may happen:

  • Due to duplicated attribute names in a given entity while running attrsvector2attrsobject.py. The symptom of this problem is getting errors like this one:

    - <n>: dupplicate attribute detected in entity {"type": "...", "id": "...", "servicePath": "..."}: <AttrName>. Skipping

    This may correspond to entities created with Orion 0.17.0 or before, which were using the name-type combination to identify attributes. The solution is to remove the duplicate attribute and re-run attrsvector2attrsobject.py again. The procedure to remove duplicate attributes is documented in this post at StackOverflow.

  • Due to some unexpected problem during DB updating. The symptom of this problem is getting errors like this one:

    - <n>: ERROR: document <...> change attempt failed!

    There is no a general solution for this problem, it has to be analyzed case by case. If this happens to you, please have a look to the existing questions in StackOverflow about fiware-orion in order to check if your problem is solved there, otherwise create your own question (don't forget to include the "fiware-orion" tag and the exact error message in your case).
