In ArcGIS 10.2 with I type n the command line:
sdemon -o info -I users -s <server number> -i <service number> it works,
but when I type the the same command using Oracle Direct Connection it fails
sdemon -o info -I users -s <server number> -i sde:oracle11g:<instance>
I get the following error message:
Entry for SDE instance not found in services file, Unable to get users
This last syntax worked in ArcGIS 10.0
Which version of Oracle are you using? What client are you using (Administrator or Instant)? In case of Administrator client, see if the entry of the service in services file is there in client TNSNAMES.ORA file as well. If not copy it from Oracle home services file.
I hope that works.
I am using Oracle 11G, with ArcSDE 9.3 for one instance and ArcSDE 10.0 fopr other instances.
The client is ArcGIS 10.2.2
From ArcCatalog I am able to see all the isntances. Yes I do ahve the Geodatabase Administrator opetion in the menu, but I aam not SDE suepr suer only wht owner of the schema.
