An interesting and an important tip on SMTP relay

Friday, 20 April 2018 02:57

 

We had a peculiar issue in one of the SAP environment where the emails were failing intermittently, upon further detailed analysis, we understood that mails were failing whenever SAP server used a particular exchange server to process them.  As you all may know that we generally check  telnet 25 to check whether the SMTP is relayed for a particular client (SAP Server/host) or not, but in our case telnet to SMTP host was working absolutely fine, but still the problem was occurring intermittently.  In this article, I have described few other important steps to be taken to understand whether your SAP server is really authenticated to send mails through the exchange server configured in SCOT settings.

Never Attempt to Add Support Pack Related Transport Requests into Buffer Manually @ OS Level,

Friday, 20 April 2018 02:57

 

Once we had a situation where the transport buffer got corrupted after the DDIC_ACTIVATION phase of Support Pack Upgrade, according to SAP, it is not possible to reset the queue if the DDIC_ACTIVATION phase is crossed, the only option is to roll back using the backup taken prior to Support Pack upgrade. But in our situation, we did not want to reset the queue/roll back, but wanted to try to add the support package related transport requests into buffer manually using tp addtobuffer command. SPAM did not really detect that we added the transport requests manually and it let us to proceed further without any warnings/errors. To our surprise, each and every step of support pack upgrade got completed successfully, but at the end of all the necessary upgrade steps, SPAM introduced an additional step called "Generation of Programs and Screens" which is nothing but  Compilation/SGEN for every object stored in each of the support package requests.

Table Buffering - ST02

 

Buffering Types

Single-Record

 

Single-record buffer (what you see in ST02) contains the data that is needed for accesses that are performed using all table keys of a table, for example, query with all the primary keys specified in the where clause.  The buffering concept works as usual, each record that is fetched from the database for the first time is placed in the buffer, whenever the same record is requested by the query, it can be read from the buffer instead of disk.

 

For example
