Installed solution manager 7.2 abap and java under one container

Recently I installed asolution manager 7.2 abap and java under one container Oracle multitenant 19c, here I am sharing some important tips, hope can help in the future. Especially second system installed into container is more interested.

SAP NOTES:
2336881-Using Oracle Multitenant with SAP NetWeaver based Products
2884255 – Using Oracle Database Services for SAP NetWeaver for Multitenant Databases
2333995-BR*Tools support for Oracle multitenant database

System structure:

OS user:
oracle => still oracle user as oracle software owner, which also used to install oracle software
oracdb => containder database ora<sid>
a07adm => abap/A07 admin user <sid>adm, which can admin database as well
j07adm => java/J07 admin user <sid>adm, which can admin database as well

there is no ora<sap sid> user for each SAP system any more

ABAP system installation SID=A07, I will only pasted database relevant parts:

then in swpm click continue

JAVA system installation SID=J07, I will only pasted database relevant parts:

here you give existing CDB ID, SWPM will detected it, and install pdb into it

here has option value PDB in “Inlstall Additional Pluggable Database”, not sure what it means, and selecting PDB gives error:
