I did a reorgchk and it showed a few indexes needed reorg. So i ran this script:
FORCE APPLICATIONS ALL;
CONNECT TO DOMINOS;
-- [SYSIBM].[SYSTABLES].[INDTABLES01]: [*----];
REORG INDEXES ALL FOR TABLE SYSIBM.SYSTABLES REBUILD;
-- [SYSIBM].[SYSPLAN].[INDPLAN03]: [*----];
REORG INDEXES ALL FOR TABLE SYSIBM.SYSPLAN REBUILD;
-- [SYSIBM].[SYSVIEWDEP].[INDVIEWDEP01]: [*----];
REORG INDEXES ALL FOR TABLE SYSIBM.SYSVIEWDEP REBUILD;
-- [SYSIBM].[SYSPLANAUTH].[INDPLANAUTH02]: [*----];
REORG INDEXES ALL FOR TABLE SYSIBM.SYSPLANAUTH REBUILD;
-- [SYSIBM].[SYSVARIABLES].[INDVARIABLES03]: [*----];
REORG INDEXES ALL FOR TABLE SYSIBM.SYSVARIABLES REBUILD;

Then ran reorgchk again, only to find out they still need a reorg (scroll to the right):

As you can see, they all show an exceed (*) in the F4 formula, and according to the documentation:
If the results of the calculations for Formula 1, 2 and 3 do not exceed the bounds set by the formula and the results of the calculations for Formula 4, 5 or 6 do exceed the bounds set, then index reorganization is recommended.
