General Information
SAP Upgrade means a scenario, when the SAP application (S/4, ECC, BW, CRM, DMIS, etc.) or major NW version is being upgraded, while Glue is installed as an add-on on the system.
...
In an ideal scenario, Glue triggers are only inactive during periods in which no transactions are happening in the system. In scenarios when this is not possible, after the upgrade is finished replications that use trigger delta need to be fully reloaded (full load + delta init).
Before upgrade
Stop any currently running Schedulers (and legacy watchdogs).
Stop Java Connector in
/DVD/JCO_MNG.Disable any active triggers in
/DVD/GL_DBT. If possible, do this after any interaction with the system is forbidden.
| Note |
|---|
SAP Software Update Manager (SUM) does not allow upgrade to proceed, while any database triggers outside SLT namespace exist on SAP tables. Therefore, Glue triggers need to be disabled before SUM upgrade. Please note, that this does not include SLT Add-on scenario, in which SLT triggers are used for delta capture. |
After upgrade
If the NetWeaver release or installation number changed during the upgrade, request and apply for a new Glue license.
Activate Glue triggers in
/DVD/GL_DBT, preferably before any interaction is resumed.Reload any tables on which you might have missed changes.
Start Java Connector in
/DVD/JCO_MNG.Start schedulers.
