The GGSCI command INFO EXTRACT <group> shows that the RBA is not increasing and the LAG is increasing. Extract seems to be hanging.
Extract may be processing a long transaction.
To check, issue this command:
GGSCI> SEND EXTRACT <group>, STATUS
It should show that Extract is processing a transaction with a large number of records. To verify, issue this command:
GGSCI> SEND EXTRACT <group>, REPORT
View the report file (VIEW REPORT <group>). If WARNLONGTRANS has been implemented in the params then the report file should show messages like “Repositioning for Long Transaction” and “Finished Long Transaction, Processed nnnnn records.” This indicates that Extract is running and processing long transactions.
