Troubleshooting the installation

Troubleshooting the installation

If you encounter issues while installing Zero Downtime (ZDT), clean your environment and try again. If the problem persists, contact Informatica Global Customer Support.
  1. In the command line, run the
    sip_ant.bat undeploy_zdt
     command to clean the environment, uninstall the ZDT baseline, and remove ZDT replication.
  2. To clean the passive environment, perform the following manual tasks:
    1. Remove all the files related to the environment. 
      <GoldenGate install directory>/dirchk
del *

<GoldenGate install directory>/dirdat
del enva/*
del envb/*

<GoldenGate install directory>/dirrpm
del e_env*.prm*
del *.def

<GoldenGate install directory>dirrpt
del *.dsc
del e_env*.rpt
del r_env*.rpt
del rqenv*.rp
    2. Remove the ZDT event queue in the environment.
      Do not drop the GGS_CHECKPOINT and GGS_CHECKPOINT_LOX tables. If you drop these tables, the REPLICAT service does not start. 
      /* Repository tables for ZDT */
delete from C_REPOS_ZDT_EVENT_QUEUE;
delete from C_REPOS_ZDT_REPLICAT_EXCEPTION;
update C_REPOS_ZDT_ENV_STATE set state = NULL, state_ts = NULL, state_desc = NULL, updated_by=NULL, update_date=NULL;

/* Tables for Oracle GoldenGate */
delete from GGS_CHECKPOINT;        -- Do not drop this table
delete from GGS_CHECKPOINT_LOX;    -- Do not drop this table

drop table GGS_EVENT_CHECKPOINT cascade constraints;
drop table GGS_EVENT_CHECKPOINT_LOX cascade  constraints;
drop table GGS_EVENT_TRACE cascade  constraints;
commit;
    3. Search for %GGS% tables. Verify that the GGS_CHECKPOINT and GGS_CHECKPOINT_LOX tables exist. If you find any other tables with GGS in the table name, including TMP_GGS_* tables, you can drop these other tables.
  3. Install ZDT.
