Help yourself or the bugtracking in WebSphere products for Dummies (Part 3)

 "Revenons a nos moutons..."

There is a bug in BPM 7.5.1.
It is looking as (in SystemOut.log):

[3/7/13 15:14:50:193 MSK] 0000003d servlet       E com.ibm.ws.webcontainer.servlet.ServletWrapper service SRVE0068E: Uncaught exception created in one of the service methods of the servlet AssetDownload in application IBM_BPM_Teamworks_BPMAPS.AppTarget. Exception created : com.lombardisoftware.core.TeamWorksRuntimeException: com.lombardisoftware.client.delegate.BusinessDelegateException: Snapshot.3360e049-5350-4d8c-8f7f-b5043046186b

Caused by: com.lombardisoftware.client.persistence.common.ObjectNotFoundException: Snapshot.3360e049-5350-4d8c-8f7f-b5043046186b

It means that some snapshot does not exist.

1. Check it:

SELECT PR.NAME, SN.ACRONYM

FROM LSW_SNAPSHOT SN INNER JOIN LSW_PROJECT PR

ON SN.PROJECT_ID     = PR.PROJECT_ID

WHERE SN.SNAPSHOT_ID = '3360e049-5350-4d8c-8f7f-b5043046186b';

NAME                                                             ACRONYM                                                         

---------------------------------------------------------------- ----------------------------------------------------------------

They killed Kenny! (IBM, I mean:) What to do?

2. Let's search this text string in the <profile folder>.
We found three files (not logs) with '3360e049-5350-4d8c-8f7f-b5043046186b', for example:

cd /ibm/bpm75/profiles/ProcessServer01/installedApps/PSCell/IBM_BPM_Portal_BPMAPS.AppTarget.ear/portal.war/jsp/css>
cat coach_designer_systoolkit.css

@import url("/teamworks/webasset/2064.3360e049-5350-4d8c-8f7f-b5043046186b/toolkit/TWSYS/W/coach_designer_base.css");

/* Leapfrog Coach skin override. */
@import url("/teamworks/webasset/2064.3360e049-5350-4d8c-8f7f-b5043046186b/toolkit/TWSYS/W/skin1.css");

3. Try to open our hyperlink, for example:

https://bpm-tst-ps-www1/teamworks/webasset/2064.3360e049-5350-4d8c-8f7f-b5043046186b/toolkit/TWSYS/W/coach_designer.css

What to be proved...

4. Let's continue. In one ffdc file we found these strings:

com.ibm.ws.webcontainer.servlet.CacheServletWrapper::cacheKeyStr:bpm-dev-ps-www1:443/teamworks/webasset/2064.e705fca0-1d30-4d53-ad80-4995d8486cd0/toolkit/TWSYS/W/coach_designer.css

com.ibm.ws.webcontainer.servlet.CacheServletWrapper::isValid:true

It means that the hyperlink:
https://bpm-dev-ps-www1:443/teamworks/webasset/2064.e705fca0-1d30-4d53-ad80-4995d8486cd0/toolkit/TWSYS/W/coach_designer.css
can be open...

What is this snapshot?

SELECT PR.NAME, SN.ACRONYM

FROM LSW_SNAPSHOT SN INNER JOIN LSW_PROJECT PR
ON SN.PROJECT_ID     = PR.PROJECT_ID
WHERE SN.SNAPSHOT_ID = 'e705fca0-1d30-4d53-ad80-4995d8486cd0';

NAME                                                             ACRONYM                                                         

---------------------------------------------------------------- ----------------------------------------------------------------

reports                                                          3.2.17

Oh, it is one of snapshots of one of my process applications. But I cannot use this id in the others servers (the snapshot exists only there).

But, possible, I can use some standard PA. What is it? Surely, Process Portal!!!

SELECT SN.SNAPSHOT_ID

FROM LSW_SNAPSHOT SN INNER JOIN LSW_PROJECT PR

ON SN.PROJECT_ID           = PR.PROJECT_ID

WHERE SN.ACRONYM           = '7.5.1.1'

AND PR.SHORT_NAME = 'TWP'

SNAPSHOT_ID                         

------------------------------------

30564a93-8ad4-485b-b356-b0d2c6f95b75

4. Try to open:

https://bpm-tst-ps-www1/teamworks/webasset/2064.30564a93-8ad4-485b-b356-b0d2c6f95b75/toolkit/TWSYS/W/coach_designer.css

BINGO!

5. There is a very simple solution.

Step 1. Run /<WAS_HOME_FOLDER>/BPM/Lombardi/tools/portal-app/redeployPortal.sh
Process Portal PA will be unpacked in this folder.

Step 2. Change IDs from 3360e049-5350-4d8c-8f7f-b5043046186b to 30564a93-8ad4-485b-b356-b0d2c6f95b75 in three files - coach_designer_systoolkit.css, coach_designer_base_systoolkit.css, skin1_systoolkit.css (I use mc in Linux for this. F4 - Edit File, F4 - Replace).

Step 3. Run redeployPortal.sh one more time. Portal will be packed and deployed.

Step 4. Repeat the step 2 for three files in TWSYS toolkit - coach_designer.css, coach_designer_base.css, skin1.css. Check your Process Applications - they must linked to correct files.

Step 5. Restart WAS and forget about this issue...
