All Receiving Transactions Fail with rvtptcontrol Error

Applies to:

Oracle Application Install - Version: 11.5.10.0 and later.

Oracle Inventory Management - Version: 11.5.1 to 12.1.3

Description:

All Receiving transactions fail with rvtptcontrol. After some research work I found that the error occurs when many transactions fail with same error it is usually because the receiving executables (RVCTP and RCVOLTM) are out of sync.

Solution:

1. Resolve INVALID Objects

1.1 Set environment

1.2 cd $ORACLE_HOME/rdbms/admin

1.3 sqlplus / as sysdba

1.4 SQL>@utlrp.sql

2. Relink Receiving executables

2.1 cd $AD_TOP/bin

2.2 sh adrelink.sh force=y ranlib=y "PO RCVOLTM"

2.3 sh adrelink.sh force=y ranlib=y "PO RVCTP"

3 Bounce Receiving Transaction Manager:

3.1 (System Administrator > Concurrent > Manager > Administer)

3.2 Deactivate Receiving Transaction Manager

3.3 ps -ef | grep RCVOLTM (repeat until no processes are running)

3.4 Restart Receiving Transaction Manager

4 Perform transactions and retest the issue

5 If the transaction still fails, bounce the database and then perform another transaction.

6 If bouncing the database or flushing Shared Pool resolves the issue only for a few days (or a few weeks) and bounce database (or flush Shared Pool) must be repeated periodically to resolve the issue, please log a Service Request.
