https://www.ibm.com/developerworks/community/wikis/home?lang=en#!/wiki/Anything%20about%20Tivoli/page/To%20load%20the%20sample%20DB2%20database%20after%20Control%20Desk%207.6%20installed
But I didn't find those steps before I started, so I took my own path.
Specifically, I didn't drop the database, and that meant that I encountered errors BMXAA7025E and BMXAA8313E when running the 'maxinst.sh' script. What I found is that the cleandb operation doesn't really delete all of the tables and views in the MAXIMO schema (I'm on DB2/WebSphere/RHEL 6.5), so when maxinst gets to running the files under:
/opt/IBM/SMP/maximo/tools/maximo/en/dis_cms
It fails because a few of these SQL files try to create tables and views that still exist. I found this link about the problem:
https://www-01.ibm.com/support/docview.wss?uid=swg21647350
But I didn't like it because it tells you to re-create the database. So with a little digging, I found that after I hit the error, I could run the following db2 commands to delete all of the tables and views that were not automatically deleted:
db2 connect to maxdb76 user maximo using passw0rd
db2 DROP TABLE ALIASES
db2 DROP TABLE ATTRIBUTE_TYPES
db2 DROP TABLE BNDLVALS
db2 DROP TABLE BUNDLENM
db2 DROP TABLE CDM_VERSION
db2 DROP TABLE CHANGE_EVENTS
db2 DROP TABLE CLASS_TYPES
db2 DROP TABLE CMSTREE
db2 DROP TABLE CMSTREES
db2 DROP TABLE DESIRED_SUPPORTED_ATTRS
db2 DROP TABLE DESIRED_SUPPORTED_MAP
db2 DROP TABLE ENUMERATIONS
db2 DROP TABLE FTEXPRSN
db2 DROP TABLE FTVALUES
db2 DROP TABLE INTERFACE_TYPES
db2 DROP TABLE LAPARAMS
db2 DROP TABLE LCHENTR
db2 DROP TABLE LCHENTRY
db2 DROP TABLE ME_ATTRIBUTES
db2 DROP TABLE METADATA_ASSN
db2 DROP TABLE MSS
db2 DROP TABLE MSS_ME
db2 DROP TABLE MSS_RELATIONSHIPS
db2 DROP TABLE NAMING_IDENTIFIERS
db2 DROP TABLE NAMING_POLICIES
db2 DROP TABLE NAMING_RULES
db2 DROP TABLE RELATIONSHIPS
db2 DROP TABLE RELATIONSHIP_TYPES
db2 DROP TABLE SBSTVALS
db2 DROP TABLE SUPERIORS
db2 DROP TABLE VALID_REL_TYPES
db2 DROP VIEW ATTR_PRIORITIES
db2 commit
And then I could re-run the maxinst.sh script and it worked like a champ. Please feel free to use my super secure password for yourself.
