retrive error Ice.MemoryLimitException

[jmoore]

If you have the group id, then you can use adminServicePrx.containedExperimenters(groupID). That returns a list. On each of those, you can call: experimenter.getId().getValue() to get the id.

P.S. Sorry for having missed your comment on the 3rd!

thanks a bunch for the help, josh, really quick one.

A new problem. No data can be retrieved rather than the log in user.

I would like to retrieve all user's data in one shared group as a admin.

here is the summary again,

// connect as admin;
myClient = new client (hostName, portNo);
myEntry = myClient.createSession(userName,passwd);

// how many groups in;
List <Long> allGroupIds = myEntry.getAdminService().getEventContext().memberOfGroups;
for (int n=0; n<allGroupIds.size(); n++)

// experimenter ids in one group;
List <Experimenter> expts =myEntry.getAdminService().containedExperimenters(groupId_);
Iterator <Experimenter> i = expts.iterator();

// obtain one experimenter's data in one project
IContainerPrx proxy = myEntry.getContainerService();
ParametersI param = new ParametersI();
(*) // myEntry.getAdminService().getEventContext().userId;

(**) long userId =lon_userId;
param.exp(omero.rtypes.rlong(userId));
param.noLeaves();


List<IObject> results = proxy.loadContainerHierarchy(Project.class.getName(), new ArrayList<Long>(), param);

Iterator<IObject> i = results.iterator();


The problem is that if the userId at (**) is other than the id got by (*), the Project brings back nothing.

I assume myEntry is specified by log in user, cannot shared with other users.

How can i modify this please?

cheers

Hi Jiez,

I'm not sure exactly what's going wrong in your snippet, though it's likely caused by looking at other groups at the same time. I've updated my gist, perhaps that will help. If you could provide a complete running example (perhaps by forking that gist), it would make it much easier to know what's going wrong.

The output for that change when I run it begins like this:

Code: Select all

The connection is set up and userId is:15**.

groupId is:8**.

thanks Josh.

A little bit weird. I made no changes to previous version but log in to count image numbers in one project with OMEROinsight, and after this, It CAN retrieve other users' data now.

anyway , i'll try your new template .

I would assume that's an issue of your default group changing. Perhaps your group wasn't what you expected when testing previously?

Anyway, good to hear that it's working. Let us know if there's anything else you need.

I read through the permission doc
https://www.openmicroscopy.org/site/support/omero4/sysadmins/server-permissions.html

cannot figure out the admin's roles in manipulating group member's data. what methods are available for admins ?

for example, when I log in as a admin

Code: Select all

// connect as admin;
myClient = new client (hostName, portNo);
myEntry = myClient.createSession(admin,admin_passwd); 
// do stuff of groups, experimenters, projects, datasets;
.........



Then later on, I need to change the role as a specific group member grp_mb_1 to do something ,e.g.,

Code: Select all

ServiceFactoryPrx  myEntry_mb = myClient.createSession(grp_mb_1,grp_mb_1_passwd);
ThumbnailStorePrx store = myEntry_mb.createThumbnailStore();
// doing thumbnails;

...... 


Why changes the role ? I found myEntry (admin) cannot retrieve rp_mb_1 's thumbnails properly, but myEntry_mb does.

So, is there a way to obtain grp_mb_1's password as a admin? We not use LADP accession, but user(passwd) . OR, are there simple methods that allow admin acting as grp_mb_1 temporarily like myEntry_mb.createThumbnailStore()?

thanks.

Each session is in a specific security context, usually a group. By changing this value, you can view data from a different group. Here is how insight makes the change:

thanks josh. i need some time to digest that.

A quick question,

is method available in Experimenter for password similar to getPassword() like id "Experimenter.getId().getValue()" ?

http://hudson.openmicroscopy.org.uk/job/OMERO/javadoc/slice2html/omero/model/Experimenter.html

does not mention them .

Sorry, but the password is not exposed via the API at all. You can only set the password for the current user via IAdmin.changePassword(RString) or for another user via IAdmin.changeUserPassword(string name, RType newPassword). If you are using LDAP, you can't change the passwords via OMERO at all.

~Josh.
