Find Size of PeopleSoft Tables and indexes [SQL]

What is the biggest pain for PeopleSoft Admins/DBA or any PeopleSoft consultant supporting the application? That's when performance of PeopleSoft application is really sluggish. There are hundreds of things that could go wrong and one of those is directly related to size of your PeopleSoft database. 

PeopleSoft database consists of PeopleSoft Tables, indexes and few other objects but primarily the size is determined by tables and indexes. 

For Oracle database, DBA could utilize OEM (Oracle Enterprise Manager) to keep a check on your database size and you could setup triggers or scripts to alert when it reaches a threshold. 

PeopleSoft Tables are the PeopleSoft record definitions that are built and have database definition. PeopleSoft Indexes are created for these PeopleSoft tables. 

Below are couple of SQLs that can be used together to estimate the size of PeopleSoft database (size of PeopleSoft tables & size of PeopleSoft indexes)

Output of below SQLs will show the size in MB and GB (approx).

-- Find PeopleSoft Table size
SELECT DS.TABLESPACE_NAME,
SEGMENT_NAME,
ROUND (SUM (DS.BYTES) / (1024 * 1024)) AS MB,
ROUND (SUM (DS.BYTES) / (1024 * 1024 * 1024)) AS APPROX_IN_GB
FROM DBA_SEGMENTS DS
WHERE SEGMENT_NAME IN (SELECT TABLE_NAME
FROM DBA_TABLES
WHERE OWNER = 'SYSADM'
AND TABLE_NAME LIKE 'PS_%'
AND NUM_ROWS > 0)
AND SEGMENT_TYPE = 'TABLE'
AND OWNER = 'SYSADM'
GROUP BY DS.TABLESPACE_NAME, SEGMENT_NAME
-- Find PeopleSoft Index size
SELECT DS.TABLESPACE_NAME,
SEGMENT_NAME,
ROUND (SUM (DS.BYTES) / (1024 * 1024)) AS MB,
ROUND (SUM (DS.BYTES) / (1024 * 1024 * 1024)) AS APPROX_IN_GB
FROM DBA_SEGMENTS DS
WHERE SEGMENT_NAME IN (SELECT TABLE_NAME
FROM DBA_TABLES
WHERE OWNER = 'SYSADM'
AND TABLE_NAME LIKE 'PS_%'
AND NUM_ROWS > 0)
AND SEGMENT_TYPE = 'INDEX'
AND OWNER = 'SYSADM'
GROUP BY DS.TABLESPACE_NAME, SEGMENT_NAME
ORDER BY ROUND (SUM (DS.BYTES) / (1024 * 1024 * 1024)) DESC;
