procedure for resetting a CCM


Dave Marsico (451914) | asked Oct 15 '13, 11:13 a.m.
I have an RTC 4.0.3 environment (linux)  with 1 JTS and multiple CCMs (using oracle DB) with a datawarehouse configured...  I'm interested in clearing the data from "ccm1",   perhaps by running repotools-ccm.sh -dropTables...  But curious what needs to be done for the data warehouse in this case... and of course if there are other/different steps for accomplishing this successfully.  Are there any documented procedures for this type of scenario?

Hi Dave,

The DW has information of the dropped CCM projects, but it will not be confused as all Projects are uniquely identified by a UUID(26 character long alpha numeric value). Sure the DW will still contain the data but it will not affect the function of other existing CCM's and their projects.

If you concern is the amount(size) of data i.e you want to trim down the DW and remove the records of the dropped CCM's projects, there is no special utility of function to achieve that. The only solution would be to drop the DW, create a new one and populate it using the ETL.

Hope that helps.
Sandy

Many thanks, that really addresses my concern perfectly.  My DW content is quite small, so I think I can live with leaving some residue if it will cause no harm.

Can you elaborate on what exactly do you want to accomplish? Dropping CCM tables will simply delete all the data from the DB (which I'm sure you are aware of), so perhaps it would be easier to simply retire the application, archive all the projects and unregister it? Then you could start from scratch using a new CCM

Piotr,  thanks for the reply/interest,   to elaborate, yes this CCM contained 100's of GB of data associated with "trial migrations" from another SCM...  So at this point the data is no longer necessary (including the project areas), so  my goal is to just wipe it clean and start over.  and reuse that ccm "URL"...   So while I believe I can  execute drop tables to wipe this CCM clean,   I'm suspecting that I am also "need" to drop the Data Warehouse as well, as it contains data from this CCM (as well as the JTS and other CCM)... Suspecting the DW may be confused if I don't...   So thats really my goal understand what all might be required...
