JTA resource impact

Enabling the database as a JTA resource manager increases the consumption of the following database resources:

After-image and before-image files — Additional notes support JTA transactions and table lock acquisition. AI and BI files need to be increased at least 30% when JTA is enabled.
Lock Table (-L) — JTA transactions will may hold onto locks for a longer period of time than local transactions.
Transaction Table — The number of rows in the transaction table is increased by the maximum number of JTA transactions. The maximum number is controlled by the -maxxids startup parameter.
Xid Table — An additional table for storing JTA transaction information. The size of the table is determined by the maximum number of JTA transactions allowed, and is controlled by the -maxxids startup parameter.
