Missing Channel

Hi,
In my Luminis portal, i found a missing channel link. I am posting the snapshot/picture of the error message that i am getting. The error numbers are:

In an administrator layout - this is the error number/message i am getting:
Channel ID: u12l1n150
Message: The 'Unknown' channel is no longer available. Please remove it from your layout.
Error type:Channel not available (code 7)

In an student-lo layout - this is the error number/message i am getting:
Channel ID:n150
Message: The 'Unknown' channel is no longer available. Please remove it from your layout.
Error type:Channel not available (code 7)

I tried to delete the channel in the student-lo layout and it didn't give me an option to delete the channel.

I was wondering if anybody encountered this situation before and if you did, what did you do to take care of it.

Thank you,
ask0500

This happened us a while

This happened us a while ago, it occurs when someone deletes the channel, before it is removed from layouts, here is the solution we got from Sungard, it's not ideal but it did work:
David,

One of the workarounds for this would be to create another dummy channel, then modify that channelID to match the ID of the missing channel.
So if you query the UP_LAYOUT_STRUCT table for the NAME of a structure ID of the missing channel (You should see it in the empty frame where channel should've been Ex u27l1n19 )
select * from UP_LAYOUT_STRUCT where NAME = 'u27l1n19'
See if there is an entry in CHAN_ID column for this channel.
If there is, go to UP_CHANNEL and modify an ID of existing (dummy) channel to match this ID.

IF there is no CHAN_ID value in the structure record, try to modify this UP_LAYOUT_STRUCT record and update CHAN_ID, NAME, TYPE to match another existing channel.

Please check with your DBA if you have further questions regarding queries that need to be run in your environment.
Also, please make sure to have all the DB tables backed up before making changes.

Thank You

Hello david

We followed your proposed course of action and it worked. Thank you very much for your help. I would never have thought this on my own.

somwhat related - can't delete a tab in allusers-lo

We ran into the same problem as the OP.

As a work around, I attempted to create a new tab in the all users fragment to replace the tab containing the bugged "missing channel".

Unfortunately I ran into a new problem as a result - no matter what rights I set on the tabs/columns/channels in the layout, the option to "delete this tab" is not presented in the layout fragment. It's just simply not there.

Furthermore, this is happening for every tab on the layout fragment (not just the one containing the missing channel.)

So now I have basically two copies of the same tab (one with the "missing channel") ... and I can't remove either tab!

Oddly enough, non-layout-owners do see the option to "delete this tab" for the tabs we have that permitted on...it's just the layout owners that are missing that option.

According to the sungard documentation, I should have the "delete this tab" option under content/layout while logged in as the owner of the layout fragment in question (in this case, the All Users fragment, logged in as allusers-lo).

Has anyone seen this? Is there a config/perm. we can set to restore that option?

Make sure the column

Make sure the column permissions do not have anything unchecked, e.g. delete column etc (Check by selecting the column in Content/Layout)
