Successfully upgraded a SDE database from ArcSDE 10.0/Oracle 11.2 (64 bit) to ArcSDE
10.2.2/Oracle 11.2 (64 bit). But unable to start the sde instance which resides
on a RHEL 6.2 server. The sdemon gives this error:
sdemon -o start -H /na1/software/esri/arcsde/sdeinstances/sdet_102 -p lk5js873j
DB_open_instance()::db_connect (OCI8) error: -1
init_DB DB_instance_open_as_dba: -51
DBMS error code: -1
Could not start ArcSDE -- Check Network, $SDEHOME disk, DBMS settings and dbinit.sde.
I don't have such a problem with ArcSDE 10.0/Oracle 11.2 on the same server. The upgraded 10.2.2 database
works fine with direct connect and has been used with ArcGIS 10.3 server and
Portal for 6 months with no issues. However, we need to start the sde instance
to support an application which only works with 3-tier (sde service)
connection.
