   2. On Web/App servers.
2.  Run in a Tc command window
   1. clearlocks -assert_all_dead
   2. install -lock_db
3.  Delete the shared memory directory
   1. TC_SHARED_MEMORY_DIR
4.  In custom env file (or directly in tc_profilevars.bat)

5.  Run in a Tc command window
   1. generate_metadata_cache -u=infodba -p=infodba -g=dba -force
6. Optionally clean u

8. Restart the environment (servicesprocesses)

Default Values

TC_NO_TEXTSRV_SHARED_MEMORY = FALSE

TC_USE_LOV_SHARED_MEMORY = TRUE

TC_USE_METADATA_SHARED_MEMORY = TRUE

TC_USE_PREFS_SHARED_MEMORY=TRUE

Notes

The side effect of turning off shared memory is that each tcserver takes additional memory as below.
