Execute at the command prompt pdm_vdbinfo we would see these informations
Num Requests pending = 900
Actual num idle = 0
-> This information show lot of queries are on pending, there is no free dbagent to process query. We could be in situation of bottleneck on the database.
1/ Verify on the local SDM server to see if we have many long queries.
Search "milliseconds" in the local NX_ROOT\log\stdlog.* , we would see the tables with long queries.
2/ If we do not have long query on the local SDM server, verify if we are in AA mode and the database is slow due to queries from other Application servers. Then search on the other application servers for long queries.
3/ Check if any index is missing on the slow table (not created due to error on cloning the mdb)
This query could be executed with your dba via sqlplus
set pagesize 0
set long 90000
set linesize 9000
set feedback off
set echo off
FROM USER_INDEXES u;
This will generate the create index in mdbadmin_schema.sql
Do the same for the mdb source and compare the create index from source and target mdb. Would help to identify missing index
