Please refer to the CABI Cleanup Guide attached to this article.

As of March 28, 2024, the attached Cabi Cleanup Script is applicable to both 20.4 and 23.4 versions, including Windows Authentication.

Oracle

Post cleanup script execution, if your backend UIM database is Oracle, you MUST add this sequence after running the script otherwise cabi will fail:

CREATE SEQUENCE  "CA_UIM1"."HIBERNATE_SEQUENCE"  MINVALUE 1 MAXVALUE 9999999999999999999 INCREMENT BY 1 START WITH 204000 CACHE 1000 NOORDER  NOCYCLE  NOKEEP  NOSCALE  GLOBAL ;

Windows Authentication

If you're using Windows authentication to access the backend database, permission to access and delete the following folders/files needs to be provided, otherwise, the script will fail to do proper cleanup of cabi:

1. c folder 
2. lib folder
3. jre folder
4. probes/service/cabi 
5. probes/service/wasp

Additional changes in case of reinstall of CABI when CABI is also deployed with OC on same server ( which is supported from 23.4)
 
Sometime if CABI probe is deployed on OC robot ,wasp may not start in that case we need to delete the below section inside wasp.cfg 
and these steps need to be followed before installing CABI.
 
1.
 
 cabi = /xxx/xxx_hub/xxx-cabi/cabi
 
2. 
 
 <cabi>
        reloadable = true
        cross_context = true
        load_on_startup = true
        unpack_war = true
        path = /cabi
 
 </cabi>
 
3. 
 
 <cabijs>
         cross_context = true
         load_on_startup = true
         skip_jar_scan = false
         path = /cabijs
 
</cabijs>
 
 
Note: Please take a backup of the wasp folder before the above procedure 

        Redeploy the ump_cabi probe on the OC server after the cabi reinstall
