Custom index on GL_BALANCES table
We are planning to create index on gl_balances
updating the existing Index GL_BALANCES_N2 on GL_BALANCES table with 3 columns (Period_name, ledger_id, currency_code ).
This is to improve the performance of the programs , and in testing we observed a good results ..
Do this effect this index in any other scenarios or will it effect me if any patch oracle releases on gl_balances in future ??
Which one is better .. create new index or update the Existing N2 index
Thanks,
Rajesh P
