Frequently facing critical object proplem

Dear All,

We are using ERP 6 EHP5 with Oracle 11G and windows 2008 on VMware environment.

We are scheduling every month cost-run report and It would be completed time one days or more than 35 hrs.So that time we facing critical objects alert and also background job had been canceled immediately.

We are facing frequently this problem. Please any body give us good solution.

Temp solution:

If I extended 3 or 4 GB for the particular table space then it will complete the job successfully.

Note :

We don't have more space in our storage.

Normally our database's all table space size less than 60 %.

Our database size is 2 TB.

Please see the below alert screen

    It's been while I did not see the old tablesapce layout (=>355771 - Oracle: Explanation of the new tablespace layout )

    You can easily save 25 Gb by deleting table CNVCLU as explained in the here under note

    719989 - SLO: Deleting data from CNVCLU after conversion

    Table TST03 is quite big, make sure you have scheduled the report to cleanup TemSe

    48400 - Reorganization of TemSe and Spool

    Data from table EDI40 could be archived/reorganized

    You can easily save space by activating index compression on the biggest index.

    This will save space and increase index access speed.

    You can also activate advanced (OLTP) compression on the biggest tables

      DMTS to LMTS conversion need a database/tablespace export and import.

      Better you do with compression so that you can get other benefits as well.

      For one of our system we followed the same to achieve both, scenario is below:

      1) Extend storage (Add 60% of additional storage to your system)

      2) Create new tablespaces in new storage (New tablespaces will be created as LMTS by default)

      3) Migrate the data from old to new tablespace with compression option ON

      4) Swap the tablespace names

      5) Drop old tablespaces and then the old storage

      Above activity will migrate all of your tablespaces to LMTS and it compress your database (you will get a good benefits in terms of storage cost saving, performance improvements etc.).
