Logical Standby out of sync after archiver stuck (how to resync)

Question

Hi,
I had an archiver stuck on my logical standby database for about 4 hours this night.
2 hours later my primary db also had an archiver stuck.
After solving the problem by repairing the backup mechanism and startup of the archivelog backup I realised
that some tables are out of sync.
How can I get back all things back in sync again?
DB: 11gR2 EE
OS: RedHat Linux 5.5
Thanks

Hi,
I don't sure have or not resyncronization whole schema, but you can use with PL/SQL as
Stop SQL Apply on logical  standby  database
SQL> ALTER DATABASE STOP LOGICAL STANDBY APPLY;
on primary
SQL>  begin
  2> for t in (select table_name from db_tables where owner = '<your schema name>')
  3> loop
  4>   DBMS_LOGSTDBY.INSTANTIATE_TABLE(shema_name => '<your schema name>', object_name => T.Table_name, dblink => '<you dblink name>');
  5> end loop;
  6>end;
Start SQL Apply on logical standby database
SQL> ALTER DATABASE START LOGICAL STANDBY APPLY IMMEDIATE;If you skip DML and DDL for your schema, then you must UNSKIP DML and DDL on this tables you must add following script to PL/SQL block before INSTANTIATE_TABLEs.
DBMS_LOGSTDBY.UNSKIP(stmt => 'DML', schema_name => '<your schema name>', object_name => T.Table_Name);
DBMS_LOGSTDBY.UNSKIP(stmt => 'DDL', schema_name => '<your schema name>', object_name => T.Table_Name);Regards
